Can oil injection screw air compressor be used in food factory

Oil-injected screw air compressors are generally not recommended to be directly used in the core production links of food factories, but they can be used indirectly through post-processing equipment in specific scenarios, while oil-free screw air compressors are more recommended in food factories to ensure absolute safety. The following is a specific analysis:

limitations of oil injection screw air compressor in food factory

1. oil pollution risk the oil-injected screw air compressor will use lubricating oil during operation. These oil may enter the food processing link through compressed air, causing food contamination. The food industry has extremely strict requirements for compressed air. It is necessary to ensure that the gas is pure, oil-free and water-free to avoid the adverse effects of oil on food quality.
2. Does not meet industry standards: The food industry usually requires compressed air to comply with ISO 8573-1 Class 0 oil-free standards to ensure food safety and hygiene. Oil injection screw air compressor is difficult to directly meet this standard, even through the post-processing equipment to remove oil, it is difficult to ensure that absolutely no oil.

Potential application scenarios of oil-injected screw air compressors in food factories (to be handled with caution)

in a food factory, if some links do not require high oil content of compressed air and can effectively remove oil content through post-processing equipment, the oil injection screw press can be used indirectly in these links. For example:

1. non-direct contact with food links: Such as driving some pneumatic equipment, valves, etc., these equipment is not directly in contact with food, but it is necessary to ensure that the post-processing equipment can effectively remove oil and avoid indirect pollution of food through the equipment.
2. as a backup air source in a food factory, if the main air source is an oil-free screw air compressor, but a backup air source is required to cope with emergencies, the oil-injected screw air compressor can be used as a backup air source, but it is necessary to ensure that it will not pollute food production when switching air sources.

Food factory is more recommended to use oil-free screw air compressor

1. ensuring food safety oil-free screw air compressor adopts special oil-free lubrication design, which can eliminate the risk of lubricating oil contaminating food and meet the strict hygiene standards of the food industry.
2. Compliance with industry standards: The oil-free screw air compressor can output compressed air that meets the ISO 8573-1 Class 0 oil-free standard to ensure the gas purity during food processing.
3. stable and reliable the oil-free screw air compressor has stable operating performance, which can ensure the purity of compressed air and provide a strong guarantee for food safety.
