What are the air compressors in the food factory?

This depends on your request! If you require a high degree of oil-free cleanliness, buy an oil-free screw machine; if you can accept micro-oil, you can buy an ordinary screw machine with a refrigerated dryer, an adsorption dryer, and a 4-stage precision filter.

If the food industry is not in direct contact with food, but only pneumatic tools, it can use micro-oil, and then install a cold dryer and a suction dryer to treat oil pollution. If it is in direct contact with the product, it must be completely free of oil and water lubrication screw air compressor.

Food and beverage is important to ensure the health of consumers. In the increasingly stringent environment of environmental protection and health requirements, it is imperative to improve the food production process, especially the application of compressed air in the food and beverage industry.

According to relevant regulations and guidance, the requirements for compressed air in food and beverages are basically the same as those in the pharmaceutical industry (refer to GPM requirements). In the field of food processing, food material filling, packaging and filling machinery automation (cylinder), material transportation, ventilation, drying, fermentation, cooling and other processes need to be completely clean, dry, oil-free compressed air.

Once the compressed air contains oil, water, dust and other impurities, it will cause food pollution, which may cause hidden dangers to the health of consumers. On the other hand, food contamination can also lead to food taste, shortened warranty period, and even material scrap. If contaminated products enter the market, the health of consumers will be affected, which can lead to expensive and embarrassing product recalls or legal claims, resulting in huge property and reputation losses.

For machines without oil and water lubrication, pay attention to several points:

the lubrication part is water, and it is pure water, preferably pure water;

2, absolutely does not contain oil, but contains water;

3. Water-lubricated air compressors are single-screw air compressors, which are not a bit cheaper than dry oil-free machines.

More than 90kw, it is best to use water-cooled; water-cooled air compressor, whether it is oil-free or oil-free, need to build a simple water tower for cooling, of course, the cooling effect should be strictly better than air-cooled.
