What are the purity and safety requirements for food grade gases?

The purity and safety of food-grade gases are directly related to food quality and consumer health. Its core requirements are reflected in the following aspects. Granklin water-lubricated single screw air compressors provide standard-compliant compressed air solutions for the food industry through technological innovation. solution:

1. Purity requirements

Food-grade gases need to meet high cleanliness standards, as follows:

1. low impurity content: Solid pollutants such as dust, microorganisms, and metal particles in compressed air need to be controlled at a very low level to avoid physical pollution to food.
2. no chemical residue: The gas must not contain chemical pollutants such as lubricating oil, heavy metals, and volatile organic compounds to prevent reactions with food or odors.
3. Stable humidity control: The compressed air needs to be effectively dried to avoid excessive moisture causing moisture, deterioration or damage to packaging materials.

2. Safety requirements

Food-grade gases need to meet strict safety standards to ensure:

1. non-toxic and harmless: Gas components must comply with the safety regulations for food contact materials and must not contain any substances that may endanger human health.
2. Aseptic environmental support: In food packaging, nitrogen filling and preservation and other scenarios, compressed air needs to be in direct or indirect contact with food and needs to avoid becoming a carrier for microbial transmission.
3. Process adaptability: Gas pressure, flow and other parameters need to be stable and controllable to meet the precise needs of food processing, transportation, packaging and other aspects.

Adapting advantages of Granklin equipment

Granklin water-lubricated single-screw air compressor is designed to accurately match food-grade gas requirements:

• Oil-free core: Use water lubrication technology to replace traditional oil lubrication. No grease is involved in the compression process. Clean air without oil is directly output to eliminate the risk of oil pollution from the source.
• low-particle generating: The low-friction structural design of single screw and star wheel blade reduces metal particles generated by mechanical wear, and cooperates with the sealing and filtering effect of water media to further reduce the content of solid pollutants.
• Intelligent humidity management: The equipment can be equipped with a condensing drying device to continuously remove moisture from the compressed air through automatic drainage function to ensure that the gas humidity meets food process requirements.
• Easy to clean and maintain: The design of the waterway system is simple, and daily maintenance only needs to pay attention to water quality cleaning and filter replacement to avoid secondary pollution that may be caused by complex oil circuits.

Granklin water-lubricated single screw air compressor builds a safe and reliable compressed air supply system for the food industry with its oil-free, clean and stable performance, helping companies meet the high standard demand for food-grade gases and ensure product quality and consumer health.
