Pharmaceutical compressed air to be flushed or purged

Food enterprise air compressor selection suggestion: there is a risk of oil compressor, oil-free technology is more in line with safety standards

in the food production process, compressed air is the key power source and process medium, and its quality directly affects product safety and compliance. According to industry experience and health standards, food enterprises should give priority to oil-free compressed air equipment granklin water lubricated screw air compressor with its zero oil pollution characteristics, can provide a reliable guarantee for food production.

1. the application risk of oil compressor in food industry

1. product safety risk due to oil contamination
   the oil compressor realizes the cooling and sealing of the metal parts through the lubricating oil, and the oil molecules will be mixed into the compressed air in the form of aerosol during the compression process. In food contact scenarios (such as pneumatic conveying, packaging sealing, mixing), oil may directly contaminate the product, causing the following problems:
   • changes in the taste or appearance of food (e. g., oil residues causing product deterioration)
   • hazards to consumer health (long-term intake of trace oil may cause chronic diseases)
   • violation of food safety regulations (such as the clear requirements for the cleanliness of compressed air in the National Food Safety Standard General Hygienic Code for Food Production)
2. high maintenance costs and poor stability
   • the lubricating oil, oil filter element and oil and gas separator need to be replaced regularly, and the cost of consumables accounts for more than 30% of the total operating cost of the equipment.
   • Oil system is prone to failure due to temperature changes or improper maintenance, affecting the continuity of production
   • waste oil treatment needs to meet environmental requirements, increasing corporate compliance costs

technical Advantages of 2. Grantkering Water Lubricated Screw Air Compressor

1. root causes put an end to oil pollution
   adopt single screw plus star wheel the compression structure uses water as a lubricating and cooling medium. The water forms a liquid film in the compression chamber, completely isolating the metal parts from contact with the air, avoiding the generation of oil from the compression principle, and the oil content of the output gas is zero.

2. Meets food industry cleanliness standards

   • output compressed air cleanliness up ISO 8573-1 Class 0(Oil-free standard), can be directly used:
     • pneumatic transportation of raw materials (such as pipeline transportation of flour and powdered sugar)
     • packaging machinery drive (e. g. bottling, canning and sealing)
     • food mixing and aeration (e. g. carbonated drinks aerated, cream whipped)
   • no additional oil-water separator or activated carbon filter is required, simplifying system design

3. operation Economy and Environmental Protection

   • zero oil consumable design reduces maintenance costs by more than 40%
   • water lubrication technology reduces mechanical friction and extends equipment life to 1.5 times that of traditional models
   • wastewater discharge meets industrial water standards, no waste oil pollution risk

suggestions on Selection of 3. Food Enterprises

1. direct contact food scene
   such as pneumatic conveying, packaging sealing, mixing and other processes, must use oil-free compressed air. Grantklin water-lubricated screw air compressor can ensure product safety and avoid quality accidents caused by oil pollution.

2. Non-contact but high cleanliness scene
   such as instrument control, pneumatic valve drive, etc., it is recommended to give priority to oil-free equipment. Granklin air compressor provides a stable gas source can reduce equipment failure rate, improve the overall reliability of the production line.

3. Scenarios for special process requirements
   for food production lines that require high-temperature sterilization or low-temperature processing, ensure stable compressed air quality.

Conclusion
the selection of compressed air system in food enterprises needs to be based on product Safety and compliance as a core principle. Granklin water-lubricated screw air compressor provides zero oil pollution, efficient and stable compressed air solutions for the food industry through innovative water lubrication technology, helping enterprises to achieve a win-win situation of safe production and cost control. It is suggested that food enterprises should give priority to evaluating the application value of oil-free compressed air technology when building or transforming production lines.
