Everything tastes like porridge, the saying goes. That may be an exaggeration, but in theory, reaction flavors could make everything taste the same. Thankfully, flavorists and chemists in the flavor industry are more inventive than that, and colorful process flavors treat our taste buds to a broad palette of sensations, flavors and aromas.

A juicy piece of fruit evokes images of sunlight and warmth. But manufacturers take the reverse route and freeze the harvested products to keep their nutritious mix of minerals, fibers, and vitamins intact. Frozen fruit processing equipment takes temperatures down to around -18 °C, giving the foods an extended lease of life. Many smoothies, jams, and purees we consume are the fruit of frozen labor.

Drying meat was the prevalent method of conserving meat cuts when food could not be chilled. But dried meat products developed into delicacies and remained a culinary mainstay long after the functional need for preservation was answered with refrigeration. The ancient techniques have been replaced by dried meat processing equipment, but the time-honored recipes remain unchanged.

Fruit dehydration is the earliest form of food preservation, with the earliest written record of dried fruits dating back to ancient Mesopotamian tablets, which contain the world’s earliest known recipes. Today, some of the most popular dried fruit snacks are raisins, dates, mango, pineapple, prunes, figs and apricots. Dried fruit processing equipment helps preserve the nutrients and sweetness of the fruit and prolongs its shelf life.

From cassava to sweet potatoes, various types of vegetables are processed to make one mixed bag of vegetable chips. Mainly consisting root vegetables like taro and parsnip, vegetable chips are often introduced as a healthy alternative to potato chips. To make these chips, you first need to slice the vegetables and cook them depending on your product; you can simply bake them or fry them, deep fry them, or dry them. After this process, flavorings are added to the chips.

Made from bananas, apples, strawberries and other tasty fruits, fruit purees are beloved by both children and adults around the world. Fruits that make it into the puree go through a strict selection process. Fruit puree processing line incorporates all machinery used for selecting, washing, cleaning, crushing and sieving the fruit which ensures the quality of the fruit puree.

Basically, to make milk powder, you need to remove the water content from the liquid milk and turn it into powder. How to do it? After pasteurizing and homogenizing the milk, milk’s water content is removed through filtration, evaporation, and drying. You have then to cool and sieve it before filling the containers. Here's how you get milk powder.

A sophisticated yet autonomous three-stage lyophilization cycle

It goes by many names. Freeze drying, lyophilization, or cryodesiccation is a form of dehydration that involves freezing the product to remove its water content and then removing the ice by sublimation – this means going from the solid to the gaseous state without going through the liquid phase. Freeze dryers are widely used in the pharmaceutical industry to increase the shelf life of products such as vaccines and other injectables. Due to their ability to best preserve the flavors, freeze dryers are used for food preservation in the food industry by dehydrating high-value products such as seasonal fruits or coffee. Industrial freeze drying systems are usually comprised of multiple components including vacuum pumps, stainless steel condensers, some form of heating and lastly, a chamber for drying where the materials are placed and processed.

Food

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

Our food chain starts in the soil, growing crops and livestock. But between the fields and the stores, there is a line of industrial food processing equipment. Processes may be as minimalistic as cleaning fruit and as complex as homogenizing milk alternatives made from pressed legumes. In each case, processing technology is an important link in the food production chain.

Fruit pulp is a mass of pressed fresh fruit not meant for immediate consumption. Production of fruit pulp avoids wasting food and preserves the flavors and nutrient value of the fruit product. Processed fruit pulp is an ingredient in beverages, sauces, baby foods, jellies, smoothies, and bakery products.

Tradition and manufacturing procedures dictate the distinction between fruit juice, puree, and pulp. Still, naming and labeling are complex and depend on regulations, type of fruit, texture, consistency, preservation methods, and sugar or solid content (measured in Degrees Brix). Depending on your desired output, there are various fruit pulper machines for different stages of production that make the process quicker and more efficient.

If Popeye needed spinach for his power, you need healthy snacks to boost your energy! From dried fruit chips to nuts and protein bars, healthy snacks have become more popular since the 2000s, and the global healthy snack market will reach USD 98 billion by 2025. In the wide range of healthy snacks, raw fruits and vegetables appear as the main ingredient, and these snacks focus on the high protein content and reduced fat or carbohydrate percentages. Also, “less processed” and “less amount of added chemicals” are the primary trend in making healthy snacks as the clean eating movement began after the 2000s.

Healthy snacks

A snack is a small portion of food ready to eat and simple and fast to prepare. People usually consume snacks during the day between traditional meals such as breakfast, lunch, or dinner. Snack foods include simple products such as nuts, dried fruits, peanuts as well as packaged and processed foods. Puffed corn products made by extrusion or flavored potato chips are examples of processed foods.
