In the field of food production, the quality of compressed air is directly related to food safety and product quality. In view of the problem of whether the air compressor of the food factory can use the micro-oil air compressor, it is necessary to make a comprehensive analysis from the aspects of food safety risk, regulatory requirements and industry practice.
micro-oil air compressor, as the name suggests, refers to the air compressor that releases trace oil during use. This oil may come from the lubricating oil system inside the air compressor to reduce friction and wear between components. However, in food production environments, these trace amounts of oil can pose serious food safety risks:
Oil contamination risk: The oil released by the micro-oil air compressor may contaminate food or packaging materials, affect the sensory quality and shelf life of food, and even cause food safety problems.
Microbial breeding risk: oil may become a source of nutrients for microbial breeding, increasing the risk of food contamination.
Regulatory compliance risks: The use of micro-oil air compressors may result in food factories violating relevant regulations and standards, and face legal penalties and reputation damage.
in order to ensure food safety, food plants have strict requirements for the use of air compressors:
Oil-free requirements: compressed air must not contain oil to prevent oil contamination of food or packaging materials. This requires the use of oil-free air compressor design, from the source to eliminate the risk of oil pollution.
Cleanliness requirements: compressed air shall not contain moisture, particles and other impurities to ensure the cleanliness of the food contact surface.
Microbiological control requirements: compressed air shall not contain bacteria, viruses and other microorganisms to prevent microbial contamination of food.
in view of the strict demand for air compressors in food plants, the application of micro-oil air compressors in food plants requires careful evaluation:
Direct contact with food process: in the process of food fermentation, stirring, blowing, bagging, drying and other direct contact with food, it is strictly prohibited to use micro oil air compressor. These processes require extremely high quality of compressed air, and any oil contamination may have a serious impact on food safety.
Indirect contact with food process: in the food production workshop environment, driving pneumatic equipment and other indirect contact with food process, although the oil released by the micro-oil air compressor may not directly contact the food, but still need to strictly assess its potential risks. If the micro-oil air compressor must be used, follow-up treatment and monitoring must be strengthened to ensure that the air quality meets food safety standards.
in the food industry, in order to ensure food safety and product quality, food plants usually give priority to oil-free air compressors. The oil-free air compressor adopts advanced water-lubricated screw technology or other oil-free design, which fundamentally avoids the risk of oil pollution and ensures that the output compressed air is pure and oil-free.
For food plants, food safety risks and regulatory requirements should be fully considered when selecting air compressors. The application of micro-oil air compressor in food factory should be carefully evaluated, and the follow-up treatment and monitoring should be strengthened. In order to ensure food safety and product quality, it is recommended that food factories give priority to oil-free air compressors to meet the high standards of compressed air in food production.
The medical air compressor must be controlled within 60 decibels, and the sound of the general household air-conditioning compressor (about 55 decibels), medical staff will not feel uncomfortable working in such an environment. In view of the relatively quiet environment required by the hospital, air compressors with noise higher than 60 decibels cannot be used in hospitals.
View detailsThe water-lubricated air compressor produced by Shanghai granklin group does not need to be treated. because water lubrication is adopted, it can be used only by matching the cold dryer and air storage tank at the back end and configuring filters according to special needs.
View detailsOil-free air compressor is divided according to whether the compressed air contains oil, which corresponds to oil air compressor or micro-oil air compressor. Oil-free air compressors are distinguished according to different compression forms or different host structures, and manufacturers often choose suitable models according to actual needs. Several common oil-free air compressors are: oil-free piston air compressor, no
In the field of high gas quality requirements, such as textile, metallurgy, food, chemical industry, medicine, petroleum and air separation and other places that need pure oil-free compressed air, oil-free screw compressor can provide high-quality compressed gas to meet various needs, so the application prospect
In the hospital environment, air compressors (referred to as air compressors), as important auxiliary equipment, provide stable and clean compressed air for various medical scenarios, and are the key infrastructure to ensure the smooth progress of medical activities. The following are the main application areas of air compressors in hospitals
In the compressed air industry, one of the most important developments is the use of oil-filled and oil-free air compressors. Each has advantages, depending on the application. Both are major markets. A key difference is that oil-free compressors are not as easy as oil-injected compressors.
The working principle of water-lubricated oil-free screw air compressor. Oil-free water-lubricated screw air compressor is widely used in industries requiring high-quality air sources such as medicine, food, electronics, chemical industry, packaging, etc. 10O% pure compressed air is a necessary measure to ensure the technological process and product quality. You can produce your high-grade products safely without risks.
View detailsSpraying processes are often seen in daily life, such as the surface of vehicle bodies, hardware and rubber products, and the main function is to prevent corrosion. In the painting stage often use screw air compressor to do power device. Then the painting field is on the air compressor.
Which is better, single screw air compressor or twin screw air compressor? Let's analyze it. Principle: The single-screw air compressor uses a single-screw rotor to drive two symmetrically distributed star wheels to rotate, relying on the spiral groove and the inner wall of the shell to form a closed basic volume,
At present, the completely oil-free air compressor equipment that can be seen in the market mostly adopts two schemes: "water lubrication oil-free" or "dry oil-free". Different lubrication methods lead to great differences in power consumption and machine loss and maintenance of oil-free air compressors.
