Classification standard for air pressure in food processing plants

The demand for compressed air in food processing plants varies according to process links. Scientific setting of air pressure grading standards is crucial to ensuring production efficiency, product quality and stable operation of equipment. Thanks to its oil-free pollution and stable pressure output, Granklin water-lubricated single-screw air compressor can flexibly adapt to the pressure requirements of different scenarios, helping enterprises achieve precise gas management.

Generally, compressed air pressure in food processing plants can be divided into three levels:
Low pressure section (0.2-0.4MPa): Suitable for basic cleaning and drying, such as surface dust removal during raw material pretreatment stage and residual moisture purging of containers or products before packaging. This range of pressure can effectively complete the cleaning task and avoid material damage caused by excessive pressure.
Medium pressure section (0.5-0.8MPa): Mainly used for material transportation, mixing and basic pneumatic control, such as pipeline transportation of powdery materials such as flour and powdered sugar, or power drive of fermentation tanks and mixing equipment. This pressure range can balance transportation efficiency and energy consumption and ensure process continuity.
High-pressure section (above 0.8MPa): For special process needs, such as auxiliary air sources for some vacuum packaging equipment, pneumatic support for blow molding of high-speed bottling lines, or power supply for precision testing equipment, such scenarios require higher pressure to ensure process accuracy and speed.

Reasonable pressure grading can not only avoid energy waste caused by “high pressure and low use”, but also reduce the risk of long-term overload operation of equipment and extend the service life of air compressors and gas terminals. Through the efficient cooperation of a single screw and a star wheel plate, combined with the stable pressure output characteristics of water lubrication technology, Granklin air compressor can accurately match the pressure requirements of all levels. At the same time, due to its oil-free characteristics, it ensures that the compressed air meets the food processing industry. Strict requirements for cleanliness provide reliable guarantee for production safety and product quality.
