Ancient civilizations discovered that plant extracts were useful for the treatment of pathologies. The origin of plant extraction cannot be specifically verified, but we can infer that the earliest attempts at plant extraction were more intuitive than scientific. Today, the extraction of compounds is a precise process with plant extraction systems complimenting traditional knowledge.

Plant extracts

Essential oils are known as the liquid gems of nature. The sweet-smelling essences impact not just our senses but also our biochemical and cellular make-up. Besides aromatherapy, the products of an essential oil extraction system found applications in pharmaceuticals and foods.

Detergents are cleaning agents that help remove dirt and grease from porous and non-porous surfaces. Industrial production of detergents began after World War I. Still, it was after the 1950s and 1960s that the detergent industry grew exponentially due in part to the development of new detergent manufacturing equipment.

Detergents

Liquid

Evaporation technology is used to reduce or remove the moisture content of a mixture. Considerations for choosing suitable evaporation equipment include the moisture content in the mixture, the boiling point of the solvent, heat sensitivity of the product, and the amount of material to be processed. Evaporators are used for applications such as obtaining fruit and vegetable concentrates in the food industry, concentrating aromas and herbal extracts in the cosmetics industry, and isolating active ingredients in the pharmaceutical industry.

Industrial

Concentration

Evaporation

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

Recovery

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.

<span style="font-weight: 400">The heating process is a step of raising the temperature of food, pharma, cosmetics, and many other types of products. You may employ different heating solutions for this process, depending on the type of product you intend to manufacture. Selecting the appropriate heater machine for your product is quite important since various products require different ranges of temperatures and different ways of heat transfer using exchangers. Industrial heating equipment varies in two ways - the type of material it can process and the reaction you want to achieve.</span>

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

Industrial extraction equipment unlocks the valuable compounds hidden away in natural materials. Automated extraction equipment is applied in the pharmaceutical and cosmetic industries to extract active compounds from medicinal plants or herbs. For example, extracting cannabinoids from cannabis plants. But the process is also fundamental to the food industry, recovering various components like aromas, oleoresins, and proteins.  Considerations for selecting suitable extraction technology include the type of plant material to be processed, the extract's heat sensitivity, and the production volume.

Extraction

When producing high-quality fruit jams or purees, ensuring uniform heating and preserving the integrity of the fruit pieces can be challenging. Traditional vertical systems often result in overcooked spots and loss of fruit integrity.
<h2>Enhance uniform heating and fruit integrity</h2>
The Horizontal Bowl JPB 205 by Boema S.p.A. is an advanced evaporation solution designed to overcome the limitations of traditional vertical systems.

For active ingredients, like proteins in food products, a high temperature could even lead to loss of nutrient value.


<h2>Concentrating products with steam and rotation, under vacuum</h2>
The Evapor by Okawara is a single effect, thin-film centrifugal evaporator that works under vacuum. For the concentration of heat sensitive products, viscous products, products that tend to foam and other high value products, this equipment is a good fit. The system consists of a hollow disc cone, rotating on a horizontal cantilevered shaft, using steam as a heating medium. The material that needs to be concentrated is pumped into the machine with a feed tube to have it transported to the bottom of the rotating spinning cone. Centrifugal force spreads the liquid over the heating surface in a thin layer of less than 0,1 millimeter. It passes across the heating surface in less than one second. The material like a fruit juice, dairy or other cosmetic, pharma or chemical products, is heated to the boiling point. This is controlled by the vacuum in the system. The concentrated material is then collected on the outskirts of the spinning cone by a paring tube. The product vapor will flow to a condenser where it will condensate and discharged by a pump.

The machine has a comparatively small heat transfer surface in relation to its heat transfer capacity. This results in a compact design that still has the capability to evaporate more water per unit area and doing so in less time than a more traditional evaporator. Additionally, the application of centrifugal force also helps to minimize generation of foam in a more effective way than falling film or scraped film evaporators. The evaporation temperature is between 35 to 90 C. Operating pressure is between 5,5 to 78 kPa/ 0.055 to 0.78 bar. The heating temperature can be between 60 to 100 C. Evaporation capacity is between 30 to 1,200 kilos per hour.
