Application of Oil-free Air Compressor in Food Processing Industry

Air compressors have a variety of uses in food processing. Food-grade compressed air can be used to cut and prepare products or create clean and consistent packaging. The following are some common applications of air compressors in the food industry:


· Classification and Mobile Products:

Air compressors can be used to move food and ingredients down the production line. For example, compressed air is often used to push powdered products into pipes. Compressed cylinders and air lifters are also able to move the product down faster to keep up with the necessary production speed. In the automatic classification of products, compressed air can also be used to power control valves and other pneumatic systems.

· Peel and cut products:  

Compressed air can be used to peel fruits and vegetables (such as onions) in preparation for packaging. The high-pressure air jet effectively and cleanly removes the peel from the product. Compressed air can also be used to remove shells or peels from nuts. High-pressure compressed air can be used to cut food and can often replace a knife or blade.

· Filled pastry: 

Cakes, pies, cookies and other baked goods can be filled with compressed air to help distribute the liquid evenly each time it is filled. This produces consistent fill volumes and reduces waste.

· Cooling products:  

Air knives are devices located above the conveyor belt. When the product moves down the production line, they use compressed air to cool the product. After the baked goods leave the oven, they are usually cooled using a stream of compressed air. Other foods that need to be roasted, such as nuts or coffee beans, can be cooled with compressed air. Cooling the product with compressed air can make it packaged faster after baking or baking, thereby improving production efficiency.

· Mixed products:  

Compressed air may be used to mix dry foods, such as cereals. The air compressor provides an efficient and clean way to mix the product, which is also gentle enough not to damage the product.

· Frozen Products: 

Many frozen food processing plants use air compressors to freeze products. The air compressor produces a stream of cold dry air that effectively cools and freezes the product.

· To create a wrapper:  

Blow molding can be used to create food packaging containers using an air compressor. The glass or plastic is heated inside the mold, and then high-pressure compressed air is used to press the material into the mold shape. The container is then cooled, typically using compressed air, and the mold is then removed.


Before filling the container with the product, the container can be cleaned using compressed air. This can include cans, bottles, bags and other containers. The use of compressed air in the packaging ensures that the packaging remains consistent. The air compressor can also be used for vacuum sealing after filling the package.

· Nitrogen generation:  

When packaging fragile items (such as wood chips), nitrogen is sometimes used to prevent the product from being crushed. Nitrogen is pumped into the package by means of an air compressor to pressurize the atmosphere inside the package.

· Maintain cleanliness:  

An air compressor can be used to remove excess debris or food from the production line. This is common in commercial bakeries because compressed air can be used to remove crumbs from equipment and baked goods (such as bread).
