Fermentation Industry

Air compressors perform a variety of functions in the fermentation industry. Air compressors are frequently used in the following are the areas of fermentation industry:

Sorting 

Air compressors sort the ingredients for the production of desired products and move them forward for further processing. Powdered ingredients are usually hard to sort. Compressed air sorts and forces them into pipes. 

Peeling and Cutting

Peeling and cutting of fruits and vegetables are also accomplished with the help of high-pressure compressed air. Pressurized air removes the peel of fruits and vegetables. It also cracks the shells of nuts and pulls out their peel. 

Mixing 

On a large scale, the mixing of dry ingredients is achieved efficiently by air compressors. The mixing process is carried off gently for preventing damage to the ingredients. 

Filling

Compressed air also assists in evenly distributing fillings into the cakes, pastries, pie, and cookies. The fillings look smoother and more consistent when filled with compressed air. The filling process by air compressors also prevents the wastage of the fillings. 

Cooling

Air compressors are also used for cooling baked or cocked products in the fermentation industry. A steady stream of compressed air quickly cools the food that leaves the oven and makes it ready for packaging. 

Freezing

Air compressors are used in refrigerating plants for freezing purposes. A cold and dry stream of compressed air cools and freezes various processed foods and beverages in the fermentation industry. 

Packaging

Time-taking and strenuous process of packaging is not done easily by air compressors. Compressed air conveniently cleans cans, bottles, containers, and bags and packs food and beverages in them. 

Fermentation is a vast industry. Various fermentation processes employ different types of air compressors. Following three types of air compressors are used in the fermentation industry:

Rotary Screw Compressor

Rotary screw compressor operates as a positive displacement compressor. In this type of compressor, two meshing oil-folded helical screws referred to as rotors, are used to compress air. One of the two rotors is the male rotor and the other is the female rotor. 

While rotating, the leading strip of the male rotor approaches the contour of the female rotor and traps air. As the air moves down the grove of the female rotor, the volume of air is compressed. The male rotor approaches the end of the groove and the trapped air is released via the airend. The rotary screw compressor is also equipped with an internal oil-cooling system to maintain the internal temperature. 

This type of compressor is used for sorting and peeling raw materials, filling cakes, pastries, and cookies, mixing, and freezing food products. 

Reciprocating Compressor

The reciprocating compressor also functions as a positive displacement compressor and reduces the volume of air by increasing the pressure. 

This type of compressor takes in an adequate quantity of air in large cylinders. The crankshaft drives the pistons in cylinders and the pressure over the air increases.  Increased pressure compresses the air and reduces its volume. 

Reciprocation compressors are either water-cooled or air-cooled. Mostly they are also lubricated for smooth functioning by oil, but non-lubricated compressors are also available. Variable capacities and pressures are also available. These compressors are often used for the freezing and packaging of fermented food. 

Centrifugal Air Compressor

Centrifugal compressor operates as a dynamic compressor. These types of compressors increase the velocity of air by a rotating impeller. The kinetic energy of fast-moving air is used to elevate the pressure by slowing it down with the help of a diffuser. 

Centrifugal air compressor is designed for continuous use and has a higher capacity than other types of compressors. It is an oil-free compressor and thus requires little maintenance. This compressor is used for various processes of aerobic fermentation where a continuous flow of oil-free air is required. 

Air compressors are widely used in the fermentation industry for the effective processing of food and beverages to meet market demands. Compressed air provides clean, fresh, and quality food by improving the efficiency, productivity, and cleanliness of various processes of food production. Consult the experts to learn about the type of compressor that will suit your fermentation product. With the proper use of the right type of air compressors, your fermentation product will surely hit the market.

• If the compressed air will be applied to the fermentation industry, we suggest using a 100% Oil-free type air compressor with an air dryer and filters.
• If the requirement for dew point is -20~-40℃, we suggest using a adsorption air dryer.
