Air Compressor in Food Industry

The Application of Air Compressors in Food Production
In the modern food industry system, compressed air has become the third largest industrial energy source after water and electricity. As the core equipment for providing compressed air, air compressors meet the food industry's demands for air purity, operational stability, and energy efficiency through their unique technology. Especially with the revolutionary upgrade of oil-free screw technology, compressed air systems have become an important link in ensuring food safety.


Standard requirements for compressed air in the food industry
1.Class-0 Oil Free
According to ISO 8573-1 Class 0 certification requirements, compressed air that comes into direct contact with food must be 100% oil free. The residual oil content of traditional oil containing air compressors is generally 0.1mg/m ³, which can cause food contamination. Oil free screw air compressors have achieved completely oil-free technology, eliminating pollution risks from the source.

2. Microbial control
It is necessary to ensure that the total number of bacteria in compressed air is less than 100 CFU/m ³, and the activated carbon filter and ultraviolet sterilization device equipped with oil-free air compressors can effectively inhibit the growth of microorganisms.

3. Stable operation of air compressor
The food production line requires air pressure fluctuations not exceeding ± 0.1 bar, and Airfler's permanent magnet variable frequency screw air compressor can achieve a pressure accuracy of 99%.


The specific application of air compressors in the food industry
1. Raw material processing
The pneumatic conveying system for powdered materials uses 0.6-1.5MPa oil-free compressed air, which increases the conveying efficiency by 43%. In the fermentation process, oil-free air provides pure oxygen for microorganisms, and yeast activity is increased by about 18%.

2. Packaging
The vacuum packaging adopts an oil-free vortex compressor, and the residual oxygen content can be controlled below 0.45%.

3. Cleaning and disinfection
15bar high-pressure oil-free air is used for blowing processing equipment, which saves 63% of water compared to traditional water washing methods and has no risk of secondary pollution.

Daily maintenance of air compressor components for food use
1. Filter element
Every 1000 hours of operation

2. Oil filter
Every 1-2 months of work

3. Working environment
The working environment temperature should be between 3~50 ℃, avoiding humidity, and daily machine cleaning should be done well. Discharge the sewage from the gas storage tank at least once a week and keep it dry.
