In food enterprises, the quality of compressed air is very important to the hygiene and safety of the production process. For the oil content of compressed air, although different food companies may have different specific requirements, they usually follow certain standards and specifications to ensure that the quality of compressed air meets production needs.
Generally speaking, the standard of food-grade compressed air is mainly concerned with the content of pollutants such as oil, moisture, microorganisms and dust in the compressed air. Among them, the oil content is one of the important indicators. Since the oil that may be contained in the compressed air can cause contamination to the food, the oil content in the compressed air must be strictly controlled.
Specifically, for compressed air that is in direct contact with food, its oil content should be as low as possible, and it is best to achieve a state of no oil or very low oil content. This usually requires the use of oil-free compressors or the use of efficient air-oil separators to remove the oil from the compressed air.
In addition, for compressed air that is not in direct contact with food, its oil content should also be controlled within a certain range to avoid pollution to production equipment or the environment. In general, the oil content of such compressed air should be below specific limits, such as the oil content classes specified in ISO 8573-1.
In general, the requirements of food companies for the oil content of compressed air depend on specific production needs and product quality standards. In order to ensure that the quality of compressed air meets the production requirements, enterprises should regularly test the compressed air and take corresponding measures to control the oil content and other pollutants according to the test results.
Please note that for specific oil content standards, different countries or regions may have different regulations, so in actual operation, enterprises should follow the relevant local regulations and standards.
Should be able to calculate the pressure vessel, the general air compressor is conjoined with a gas storage tank, the gas storage tank is a pressure vessel. If the air compressor is an oil-free screw machine, there is no need to consider the pressure vessel inside the machine, because it does not have an oil and gas separation cylinder. If it is spray
Air compressor does need regular maintenance, regular maintenance is to ensure the normal operation of the air compressor, extend the service life and improve the efficiency of the key measures. The following are some detailed information and suggestions on air compressor maintenance: the importance of maintenance air compressor is a complex
Permanent magnet variable frequency air compressor and ordinary variable frequency air compressor have their own advantages, the specific choice depends on the use of scenarios and needs. Permanent magnet variable frequency air compressor adopts permanent magnet motor, which has the advantages of high efficiency, high power factor, low noise and low vibration. At the same time, the permanent magnet motor
PPM is the abbreviation of the English part per million, which means the number of parts per million or parts per million. It is usually used to express the content of trace substances in the mixture, with weight ratio (PPMw) and volume ratio (PPMv). In the field of air compressor, mentioned
Air compressors are widely used in factories, covering almost all aspects of factory production and operation. The following is a detailed summary of the main application areas of air compressors in the factory: 1. Power supply pneumatic tools and equipment: air compressors are pneumatic drills and pneumatic screwdrivers
The noise level of the screw air compressor varies depending on the type, power, design, manufacturing process and noise reduction measures taken. Generally speaking, the noise of the screw air compressor is between 60 and 90 decibels. 1. noise level range Small screw air compressor: e.g. 7
In the forging industry, the air compressor is like a tireless "pneumatic assistant", providing continuous and stable power for the production of forgings. Imagine those hot metal blanks, gradually deformed under the blow of the forging hammer, and finally became exquisite
The maintenance time and frequency of the air compressor mainly depend on the type of air compressor, the use environment, the working load and the manufacturer's recommendation. Generally speaking, the maintenance of air compressor includes daily inspection, regular maintenance and overhaul. Daily inspection: built
Granklin's water-lubricated air compressor head: the power of independent research and development and manufacturing, Shanghai Granklin Group, as a leader in the air compressor industry, has won wide acclaim for its excellent technical strength and innovative product design. In many air pressure
In the field of air compressors, the difference between oil-free and oil-free is not only reflected in the technical level, but also related to air quality and environmental protection standards. The water-lubricated screw air compressor produced by Shanghai Granklin Group has led the new fashion of the air compressor industry with its unique oil-free design.
