Changemakers

We continuously talk to suppliers of feed processing technologies that have important know-how on how to create the smarter, better, and greener feed products we need to kickstart a better tomorrow. Are you into making animal feed or pet food and looking for ways to improve your production process? Let’s navigate the world of feed production technologies together!

With the increase in the world population and rising concerns for environmental sustainability, the market for suitable new protein sources is expanding rapidly. Traditional agricultural methods alone can’t deliver sufficient protein to meet the projected food demand over the next decades. Insects provide an alternative source of nutrients. But insect protein does not mean direct insect consumption. Extracting protein and amino acids from farmed insects is more sustainable and efficient. Specialized insect protein processing technology is driving the transformation toward new protein sources.

Insect protein

Pet food is a specialty food mostly based on formulated ingredients for various nutritional and dietary requirements. Pet food formulas are becoming more diverse and complex, considering the special health conditions and needs of young and aging pets that live in cities. The production of pet food is similar to processing food in general when it comes to fresh feedstock and flesh products.

Industrial separation equipment encapsulates the separation process which is to separate components of a liquid mixture, for recovering dissolved solids from liquids. The choice of a suitable technology depends on the identification of the key physical or chemical property, such as size, mass, density, or boiling point, which sets the product of interest apart from the rest of the components. Separation technology is widely used in the pharmaceutical and chemical industries for the isolation of active ingredients and high-purity chemicals. As well as in waste management and recycling industries.

Separation

Especially designed for flue gas desulphurization, applications in coal fired power plants and waste incineration plants.


<h2>High-quality gypsum with minimal residual moisture</h2>
Gypsum centrifuges from Ferrum are used for the cleaning of the raw flue gas in a wet process with slurry of limestone to form gypsum; this process is called dewatering in desulphurization.

Dewatering is effected discontinuously in a sequence of specific process steps, which are filling, intermediate centrifugation, washing, centrifugation, scraping/solids discharge and residual heel removal.

With this system you will realize trouble-free solid-liquid separation with maximum performance, minimum energy consumption and consistent, reproducible product quality.

Also the gypsum centrifuges can be used in the construction industry instead of being dumped in environmentally harmful landfill sites.

Gypsum centrifuge

Industrial centrifuges are widely used for mechanical solid-liquid separation of components in the pharmaceutical and chemical industries. This is achieved by rapidly rotating the contents within a container to separate fluid of different densities or to remove liquids from solids.

Centrifuging

Industrial drying machines are designed to remove moisture from your product. But the drying process must cater to variations in the state of matter and molecular structure of the input material. Industrial dryer technology exploits the modes of heat transfer (convection, conduction, radiation, evaporative cooling) to control the moisture content.

Drying

Ventilex Drygenic air dehumidifier is easy to operate, eliminates airborne micro-organisms, and saves energy and investment costs.

Air dehumidifier for bulk products

Industrial dehumidification involves the process of removing moisture as well as controlling humidity. For example, warehouses that store grains need a controlled climate to avoid mildew and other moisture-related issues that can ruin or spoil the product. Refrigerant and desiccant dehumidifiers are used to reduce or maintain the level of humidity. Refrigerant dehumidifiers pass the air over a cold coil, cooling the air to the point where its water vapor begins to condense. Instead, desiccant dehumidifiers pass the air through a rotor containing a moisture-absorbing material. Commercial dehumidifiers are somewhat similar to their industrial counterpart in terms of function. The only big difference is the scale at which the equipment is being used.

Dehumidifying

Bagging is the process of packaging measured portions of a product into bags that protect it from spoilage, enable easy and safe transportation, and secure the product against tampering and pilferage. The choice of bagging equipment depends on the desired mass or volume per bag, the flow characteristics of the product, and bag construction and design. Bags vary in size from small sachets to bulk flexible containers. Bagging systems are often the last processing step that is generally integrated into a production line.

Bagging

Dosing systems are a line of hoppers, feeders, filling machines, and checkweighers that operate in sync to dispense materials accurately. Dosing is an essential feature of the packaging process, whether you’re filling shampoo bottles or tea bags. But dosing equipment is critical for formulations, too, particularly in the pharmaceutical and chemical industries. Imprecise dosing may cause quality degradation in the best-case scenario. In the worst scenario, it creates serious health risks.

Dosing

Industrial measurement equipment is used as a crucial step before products leave the production line. These measuring instruments check for correct dosage and standards. Equipment for measurement and control employs a wide range of technologies to detect inconsistencies in volumes, sizes, weights, and fill levels as well as to inspect goods for quality against a set of criteria. Specialized measuring tools allow you to minimize the probability for error to its lowest possible, ensuring that both products and packaging meet your benchmarks.

Many industries that process materials in pellet, powder, or crumble form need a closely controlled drying and/or cooling process to ensure product quality. This line of cooling/drying conveyors provides this function in a highly flexible, modular design configurable to any industry.


<h2>A completely modular line of drying and cooling conveyors</h2>
Amandus Kahl’s line of cooling /drying conveyors is configurable to meet the cooling and drying needs of any industry that deals with pelletized or granular dry bulk material. Process air is drawn through a layer of the customer’s bulk product as it travels along a conveyor. The conveyor bed is either composed of slotted plates attached to driven chains, or a full fabric belt depending on the characteristics of the product being cooled or dried. The belt speed is adjustable and used along with configuration of the overall belt length to precisely determine the product retention time. For enhanced drying, process air can be heated to 200 C, but drying can also be achieved using only air at ambient temperature. Cooling is also controlled and enhanced by the characteristics of the process air and overall product retention time. The modular design of the line allows the use of several layers of belts to be stacked on top of one another and a wide variety of belt widths and lengths are available. Airflow through the array of belts can also be uniquely configured to accommodate a wide variety of process needs.

Belt dryer/cooler for pellets and granules

Industrial cooling equipment varies according to the consistency and temperature conversion demands the material you are handling, but the process typically involves heat exchange treatment as your products are conveyed through a cooling chamber equipped with extraction fans or circulating water. Temperature control is a crucial aspect of your commercial production and cooling systems are applied to a range of industries.

Cooling

Pelleting equipment transforms powdered, mashed, or grounded material into a denser cylindrical shape. Pellet processing compresses the fine material against a perforated die, where it will be shaped and cut. Although granulating and extrusion also produce pellet-like products, manufacturing pellets is a distinct process.

Pelleting

Processing of wood and biomass into pellets or other volume reduced products requires careful and consistent moisture level control. This is a line of drying conveyors specifically designed for precisely controlled biomass drying.


<h2>A fabric belt dryer for Biomass</h2>
Amandus Kahl’s Fabric belt dryers use a closely knit plastic fabric belt to both transport a layer of product and allow hot air to pass through it for drying. The fabric belt also acts as an exhaust air filter to ensure limited dust loading as dust particles are trapped in the belt as the air is drawn through it. The dryers are particularly efficient, requiring inlet air temperatures of less than 120 C making them particularly well suited to make use of waste heat from other processes. The dryers operate automatically and relevant process parameters are monitored to ensure optimum and efficient drying.  To ensure a consistent and uniform final moisture content of the dried product even as the input raw materials vary in distribution of moisture content, a product supply system is included which evenly distributes material across the belt and turns it over during the drying process.

Belt dryer for wood

Utilization of biomass for energy and other applications requires consistent and reliable compaction to increase bulk density and provide a consistent an easy to handle input product to subsequent processes such as combustion. This line of pelleting presses has been under development since the energy crisis of the 1970’s and is well suited for today’s renewable raw materials industry needs.


<h2>Robust biomass pelletizers with impeccable pellet quality and high up-time</h2>

Tablets, pellets, or briquets are formed by compactors but powder presses also help form cosmetic eyeshadow or face powder.

Compaction

Grinders use a spinning blade or rotating abrasive elements to reduce the size of various materials. The specifications, RPM and grit of the engineered grinder, will result in various particle sizes. As a result, what you want to make will determine the type of grinder you need. Grinding is used for improving the texture and flow properties of various products and to enhance the flavor of food products such as coffee, spices, sugar, nuts, sesame, poppy seeds, lentils, wheat, and rice. Choosing the right rotational speed, grinding elements, and processing power allow the grinding and shredding of a wide range of materials into coarse or fine powders. Popular types of heavy duty grinders in food processing include angle grinders, bench grinders and meat grinders.

Grinding

Milling machines are used to reduce the size of material by cutting, crushing, or grinding it. The choice of industrial milling equipment depends on the industry and the materials to work with. Besides, there is a significant difference between those aimed to remove layers from metal or other materials workpieces and those designed to reduce particle size for materials that come in bulk.

Using this device allows the customer to test pellet softness and immediately adjust the process parameters to achieve the desired results without delays and lost production time caused by waiting for more sophisticated laboratory equipment.

The pellet hardness tester allows a simple in-the-field quality control for the pelletizing process. The pellet tester comes in two versions, manual and automatic. An operator can periodically rotate the adjusting screw on the manual version at different speeds to retrieve multiple readings. The automatic unit is motorized and works independently, offering more consistency and better comparison of the hardness values taken by different operators due to potential variation in operator handling of the manual version.

Pellet hardness tester

Complex processes call for continuous tracking and monitoring systems that help you to keep the manufacturing operation under control. The technology analyzes the components in the production phase for divergence in behavior or changes in conditions. Based on advanced software applications, monitoring platforms make sure that your products satisfy the quality criteria while they are being developed.

Monitoring

Drawing samples and testing them for conformity with preset quality standards allows manufacturing units to produce a consistent quality of the product. In a batch process, sample testing systems ensures that each batch meets the specified standards. In a continuous process, product and materials testing helps in the early identification of quality issues, saving significant time and resources, and preventing a sub-standard product from reaching the market. The selection of industrial testing equipment depends on the identification of key quality parameters. These parameters may include volume, weight, viscosity, hardness, particle size distribution, sterility, gauge and containment, among other parameters. Testing machinery need regular calibration to ensure that the parameters being tested are accurate. Some of the more common testing solutions include thermal imagers, scratch testers, optical inspectors and texture analyzers.

Testing

Production of certain pelletized products requires working with output products of a pasty consistency. These products include pigments, clay, detergent additives, vitamin products, and many other products where problems of adhesion of fresh pellets are often encountered. Processing of these types of products requires a pelletizing press that allows the fresh pellets to be directly deposited on a gently transporter such as a conveyor.


<h2>A pelletizing press for depositing pellets directly onto your conveyor</h2>
Amandus Kahl produces pelletizing presses with overhead drives that allow pellets to be deposited directly onto a conveyor from above-eliminating the adhesion issues of fresh pellets often encountered with pasty products. This line of presses uses the proven technology of Amandus Kahl’s other pelletizing presses but the drive unit is above the pelletizing die rather than below it allowing gentle direct deposition of the fresh pellets onto a conveyor. The presses use pan grinder rollers to compact the input material and force it through a pelletizing die forming continuous strands of compacted product. The strands are then cut to the desired length using rotating knives.

The pan grinder rollers and knives rotate slowly ensuring optimum pellet quality and minimizing generation of noise and heat. The grinder roller speed is infinitely adjustable. The grinder roller gap and strand cutter are also adjustable for optimized pellet quality for the customer’s particular needs.

Pellet dies are readily changeable without specialized tools for easy experimentation and process development aiding the customer in developing a process that is optimized for their product. A Kahl variable speed proportion screw is often used in conjunction with these units to ensure consistent and uniform feeding of raw materials.

Pelleting press with overhead drive

Compound feed processing often requires a means of kneading and mixing input substrates with added liquid ingredients.  Careful application of pressure and temperature is needed to achieve a feed with all the desirable characteristics. Product expansion is also often desirable to achieve certain feed characteristics and lower production costs.


<h2>Use high levels of liquids to improve pellet quality without compromising throughput</h2>
Amandus Kahl’s annular gap expander consists of a thick walled tube and concentric shaft that is fitted with proportioning, mixing, and kneading elements that propel input ingredients along the tube as the shaft is rotated. The output end of the tube is partially blocked by a cone shaped adjusting element. The adjusting element is driven towards and away from the tube based on user inputs and the gap between them.

The annular gap determines the rate and characteristics of material flow as it leaves the tube. As raw materials are driven through the tube by the rotating shaft but restricted from exiting the tube by the relatively small annular gap, the temperature and pressure of the material in the tube rise to as high as 140 C and 40 bar. As the material moves through the annular gap, its pressure and temperature rapidly fall and excess liquids are flash-evaporated leaving an output product that does not require subsequent drying. Careful control of the pressure and temperature profile.

The substrate can achieve many desirable product characteristics like inactivation of harmful substances and retention of value-add ingredients like proteins. The process can absorb large quantities of liquid ingredients and other conditions that would otherwise make a substrate difficult to pelletize.

Annular gap expander for compound feed

Products can be extruded with a variety of shapes and characteristics by controlling the nozzle geometry and pressure and temperature characteristics of substrates as they are propelled through a screw style mixing machine. Precise control of pressure at the point of extrusion is essential to predictable, desirable results.


<h2>Small scale, precisely controlled extrusion of animal feed</h2>
Amandus Kahl’s Extruder OE 8 is a small batch or laboratory extruder that works on the same principal as the successful Annular gap expander design where a conical stop is used to restrict flow out of a tube as materials are driven through it by a rotating shaft. The stop is moved towards and away from the tube creating an adjustable sized gap through which material leaves the tube. Controlling the size of this gap relative to the material throughput determines the pressure under which the material is extruded and influences many of the product’s final characteristics.

These units can be provided with heating or cooling jackets and provisions for monitoring temperature and pressure. Precisely controlled product extrusion is thus achieved by applying Amandus Kahl’s patented gap control technology from the annular gap expanders to this simpler machine.

Laboratory extruder

The extruder was first developed to make lead pipes in the late 18th century. But the extrusion process technique quickly spread to other manufacturing sectors, including food, feed, and biomass products. An extruder machine presses a fluid or solid material through a die. Depending on your use case, extruders adopt single- or twin-screw systems to push the premixed feed material through a barrel. Thermal pressure applied in this step can chemically modify the mixture, so the screw system must be precisely calibrated to achieve the desired result. Finally, a knife head cuts the extruded material into your designed dimensions. Extrusion machinery produces items of a uniform size, shape, and consistency.

Extrusion

Products can be extruded with various shapes and characteristics by controlling the nozzle geometry and pressure and temperature characteristics of substrates as they are propelled through a screw-style mixing machine. Precise control of pressure at the point of extrusion is essential to predictable, desirable results.


<h2>Product shaping with easy start-up and less waste</h2>
Amandus Kahl’s Extruder OE series is an extruder line that works on the same principle as the successful annular gap expander design. A conical stop restricts the flow out of a tube as materials are driven through it by a rotating shaft. The stop is moved towards and away from the tube, creating an adjustable-sized gap through which material leaves the line. Controlling the size of this gap relative to the material throughput determines the pressure under which the material is extruded and influences many of the product’s final characteristics.

Heating or cooling jackets can be added to these units for monitoring temperature and pressure. Precisely controlled product extrusion is thus achieved by applying Amandus Kahl’s patented gap control technology from the annular gap expanders to this more straightforward machine.

Handling

A loading system feeds your continuous or batch processing machine with the specified material or item in line with the flow of production. Loaders transfer the articles from one stage of preparation to the next with uniformity and accuracy.

Loading

A hose or loading arm is needed when you load or unload fluids from a ship or transfer fluids between vessel and shore. If you want a safer, easier to operate and longer service life than a hose, a marine loading arm is the ideal solution.


<h2>Marine loading arms to meet liquid loading needs</h2>
Kanon Marine loading arms are manufactured in line with the latest requirements of OCIMF and major oil companies.

Marine loading arm

Load or unload liquids from the top of the tanks safely and securely for trucks, railcars, small or big containers, ISO containers, drums of 220 liters, etc.


<h2>Safe, hassle-free loading from the top of the tank</h2>
KANON top loading arms come in different designs depending on the application. These can be open filling systems as they are commonly used in for a wide range of products across all industry sectors. But they can also be designed for closed filling for highly aggressive liquids associated with the chemical and petrochemical industries.

Loading arms can be executed with or without vapour return or pressure line. They can outfit with top level detection (bubble pipe sensing or electronic). A telescopic drop pipe can be integrated to prevent foaming or electrostatic build up. Adding a press down cylinder will prevent arm lifting or add a drop pipe deflector to prevent dripping.

Kanon top loading arms are provided with four swivel joints for the product line and a counterweight or multi-coil spring cylinder balance system.

Top loading arm

Bottom loading/unloading arms are designed to be connected on the side or on the rear of the tanker and sometimes for both.


<h2>Safe, hassle-free loading from the side or the rear of the tank</h2>
Kanon bottom loading arms are used both for open loop and closed loop fluid transfer. The “open loop” product transfer uses a single bottom loading arm. A combination of two bottom loading arms is used simultaneously for “closed loop” product transfer. Closed loop product transfer is necessary for low density liquids.

Kanon loading arms are equipped with five swivel joints and a multi-spring balance cylinder. The use of Kanon balance cylinders ensures that bottom loading arms can be maneuvered through all positions with minimal effort.

Quality of gypsum and stucco products are highly influenced by the quality of the calcining process employed in production. Consistent grinding, purification, and drying of raw mineral inputs prior to their being entrained in the hot gas flow of the calcining equipment ensures efficient calcining and a resultant high-quality final product.


<h2>Grinding, purifying, drying, and calcining from a single piece of equipment</h2>
Claudius Peters’ EM Mill is a calcining system for gypsum and stucco with an integrated grinding mill. The mill uses free moving steel balls rather than stationary rollers which ensures uniform fine grinding while avoiding the need for any bearings inside the mill. The grinding system employed requires very little maintenance and has been known to achieve a service life of over 40,000 hours. At the base of the grinding system, a scraper acts on the ball track conveying foreign material out of the mill into the reject box.

The efficiency of the grinding system allows low material time inside the mill enhancing the controllability of the process and ensuring uniform product quality. After sufficient grinding material is entrained in a calcining gas flow of unusually high temperature which yields lower gas volumes and optimal energy consumption. The constant randomized motion of the ball grinding system ensures even and constant distribution of raw gypsum for exposure to the calcining flow.

Mill for calcining gypsum

Purification is the removal of contaminating substances and by-products to increase the level of purity of the desired substance. Considerations for choosing a suitable purification system in the industry, include the physical state of the mixture, the desired product, required level of purity, the type of mixture, heat sensitivity of the product, number of purification steps needed, and the production volume. Industrial purification systems are used for the production of pure water in the food pharmaceutical and biotech industries.

Purification

The quality of gypsum and stucco products is highly influenced by the quality of the calcining process utilized in the production. Post-processing of calcined gypsum can further enhance the product's quality and reduce production costs, all at once.


<h2>Enhanced product quality through better mixing and homogenization under controlled conditions</h2>
Claudius Peters’ Smart Gypsum homogenizer receives a fresh calcined gypsum continuously at a full temperature from the calciner and improves its quality through post-processing. The material is fed through a vertical reactor chamber with a fabric floor which evenly distributes the fluidizing air allowing the gypsum to float freely in the reactor. Additional air is injected through nozzles in a way that ensures complete mixing of the material in the reactor and outflow of a homogenous product. Moisture content of product outflow is also influenced by the characteristics of the fluidizing and additional air streams. The system can be operated at ambient or under pressurized conditions. Careful control of the processing pressure can be used to determine some characteristics of the product's outflow.

Gypsum homogenizer

Homogenization is the process of reducing particle size in mixtures to improve the consistency, uniformity, and stability of the product. The choice of a homogenizer depends on the nature of the product, desired particle size, the physical state of the ingredients, and pressure requirements during the process. Homogenization is widely used in the biotech industry for cell lysis and in the pharmaceutical industry for the emulsification of creams and ointments; it also finds applications in the cosmetics and food industries for improving the consistency and uniformity of various products.

Homogenization

Industrial mixing equipment is used to combine two or more solid, liquid or gaseous segregated ingredients into a homogenous single product. The choice of mixing technology depends largely on the physical state of the ingredients and the desired final product. But the sensitivity of the ingredients, the process temperature, and pressure requirements are also critical factors. All these parameters result in a wide range of industrial mixers.

Mixing

Quality of synthetic gypsum and stucco products is highly influenced by the quality of the calcining process employed in production. Even feeding into the hot gas flow and well-controlled retention times determine the quality of the process and the final product is stucco, wall-board, or plaster.


<h2>State-of-the-art, direct calcining technology from a single staged process</h2>
Claudius Peters’ Horizontal Impact Calciner can directly process up to 100 tonnes per hour of fine raw materials used in the production of synthetic gypsum. The design is based on Claudius Peters’ successful EM Mill calciner housing, but includes no grinding elements. Instead, fine raw materials are evenly fed to the hot gas flow via an impact plate which crushes any larger or agglomerated particles. Material flow is based on the proven EM Mill calcifier and optimized for ideal retention times and responsive controls.

Horizontal impact calciner

Quality of gypsum plaster products is highly influenced by the quality of the calcining process employed in production. Production of basic and multi-phase plaster products requires carefully controlled high-temperature processing from dedicated equipment.


<h2>Efficient high temperature calcining for plaster production</h2>
Claudius Peters’ Flash calciner is a highly efficient and reliable calciner for the production of gypsum based basic and multi-phase plasters. The equipment uses single or multiple cyclone stages to suspend raw materials for processing at temperatures up to 500 C. Using cyclone technology avoids the need for any internal moving parts and allows for reliable operation with minimal maintenance even at the high operating temperatures. Calcining at these temperatures ensures controlled formation of defined gypsum anhydrite and anhydrite II phases required for the production of plasters with short setting times. A high degree of efficiency is achieved though continuous recirculation of exhaust gasses, reclaiming otherwise wasted heat and reducing energy consumption.

Flash calciner

After the calcining process gypsum products must be cooled from temperatures of 150 C in preparation for further processing. This is a line of quick and efficient cooling systems based on proven heat-exchanger technology.


<h2>Efficient high temperature calcining for plaster production</h2>
Claudius Peters’ Rotary Drum Coolers can process up to 100 tonnes per hour of calcined gypsum products. The hot material is cooled via the counter-current indirect principal in whom cooling air is moved along through a bundle of tubes in the direction opposite the material flow. As material moves through rotating drum its heat energy is indirectly transferred to the air through the tube walls and exhausted from the system. This exhaust airflow can readily be captured and use as pre-heated combustion air for other plant processes greatly increasing efficiency. The rotating action of the drum also serves to mix and further homogenize the output product. Retention time of the material in the cooling unit is carefully controlled to avoid the formation of unwanted by-products like soluble anhydrite and dihydrite.

Rotary drum cooler for calcined gypsum products

Waste products and rejected materials are inevitably generated from any gypsum products manufacturing process. This efficiency can be greatly reduced however, with the use of a specialized crusher designed for recycling them back into the production process.


<h2>A recycling crusher specifically designed for the gypsum processing industry</h2>
Claudius Peters’ Reclaim Crusher is a milling machine specifically designed for processing wet and dry waste products from the gypsum processing industry into materials that can be blended with raw gypsum and re-introduced into the primary production process. The unit consists of a heavy duty housing and two independently rotating screws. The slow rotation action of the screws breaks the materials into pieces ideally suited for further processing into gypsum products. Each screw’s rotation is reversible and is controlled by a shaft mounted gearbox and variable frequency drive motor.

Reclaim crusher

Crushing is the process of applying an amplified force to a material to break it down into smaller pieces. A crusher is a machine designed to crush large chunks of material into smaller bits or a powder. They are used to reduce mineral rocks to smaller rocks, gravel, or dust. They are also used to reduce the size of waste materials for easier disposal/recycling or to reduce the size of a solid mix of raw materials. Crusher equipment selection depends on the physical properties of the material to be processed, the in-feed size, and the desired output particle size.

Crushing
