Food Compressor

Air compressors in the food industry
The food industry has high requirements for the purity of compressed air, which must meet the ISO 8573-1 Class 0 oil-free standard. Oil-free screw air compressors completely avoid the risk of lubricating oil contamination through dry screw design, and the oil content can be reduced to 2ppm.

The application of permanent magnet variable frequency air compressors controls the pressure fluctuation within ±0.1bar, and with the dryer cooling system, it can achieve 24-hour continuous and stable air supply, which saves 28% energy compared with traditional air compressor models.

Application of air compressors in the food industry
1. Production and processing links
Raw material processing: compressed air is used for power transmission of flour and sugar, and the 100% oil-free design avoids raw material contamination.

Fermentation process: Provide sterile oxygen for yogurt and alcohol fermentation, and oil residue will inhibit microbial activity.

Equipment cleaning: high-pressure air purges molds and air pipes.

2. Packaging and preservation system
The vacuum packaging machine relies on a stable air source to achieve rapid vacuuming in 3-5 seconds, and the nitrogen replacement technology extends the shelf life of meat products by 8 times.

During the bottle blowing process, 0.45-0.3MPa oil-free air ensures the molding accuracy of the PET bottle.

3. Automated control
The pneumatic actuator drives the filling valve and sorting robot, and the dry air with a pressure dew point of -40℃ prevents the parts from being corroded.

Types of air compressors used in the food industry
Generally, the main compression technologies widely used by food companies are screw and scroll compressors.

Rotary screw compressors: Rotary screw compressors are suitable for continuous operation and are mainly used in large facilities. They generally use twin helical screws to compress the air.

Scroll compressors: Scroll compressors are known for their ultra-quiet operation. They use two staggered spiral blades to compress the air.

The right air compressor is the key to the success of a food processing plant. Ensuring that the compressed air system is optimized according to actual production needs can save costs.
