How are oil-free screw air compressors used in the food industry?

Application in Food Industry Oil-free screw air compressor is widely used in food industry due to its many advantages. The air generated by the oil-free air compressor can be directly used in food processing, as oil-less air can prevent contamination of food, and therefore help maintain the cleanliness of the production environment. It also helps to reduce the added cost of cleaning up the oil particles left by traditional air compressors. In addition, oil-free screw air compressor is energy efficient. With its two-stage compression design, oil-free screw air compressor can save energy by about 30% compared with traditional air compressor. This helps reduce the operational costs and maintenance costs of food processing, and at the same time helps reduce carbon emissions. Because the air compressor used in the food industry must conform to the characteristics of low noise and clean natural environment, oil-free screw air compressor is a widely used in the food industry. Its use in the food industry shows this, the way pneumatic equipment is used. The compressed gas with a certain working pressure is used to promote the operation of the machine and equipment afterwards. At this time, the compressed gas is generally not immediately in contact with the food, so the quality of the compressed gas is not very high. In this use, the exhaust pressure of compressed gas is about 0.6mpa, and the gas supply is generally defined according to the business scale of the enterprise. Using the mode of air source device, the high quality compressed gas produced by oil-free screw air compressor provides continuous power for food processing and manufacturing enterprises, and indirectly operates the equipment directly in contact with food. In simple terms, indirect contact refers to the compressed air does not immediately contact the food or drink, but through other media contact with the food or drink, such as coke bottles, mineral water bottle cleaning and beverage canning. At this moment, although there is no immediate contact with food, but the quality of compressed gas requirements are also very high. The exhaust pressure of compressed gas is about 0.5-0.6mpa. According to the above two applications, it is confirmed that the application of oil-free screw air compressor in the food industry has the characteristics of convenience, low noise, easy maintenance and so on. Features of Oil-free Screw Air Compressor A oil–free screw air compressor is a common type of air compressor, which can compress air by the rotation of the screw without using lubricating oil for lubrication and cooling of the screw. Its working principle and advantages and disadvantages are as follows: Working Principle The oil-free screw air compressor is a volumetric compressor mechanical for reciprocating motion. The compression of gas relies on the change of volume, and the change of volume is achieved by a pair of rotors rotating in the housing of the air compressor. Overview of Working Principle In the compressor body, a pair of meshing helical rotors are arranged in parallel, usually the rotor with the external teeth is called the sun rotor or the sun screw. The rotor with the internal teeth is called the moon rotor or the moon screw, and the sun rotor is usually connected to the prime mover to drive the moon rotor to rotate and realize the axial positioning and bear the axial force in the compressor. The cylindrical roller bearing at both ends of the rotor realizes the radial positioning of the rotor and bears the radial force in the compressor. At both ends of the compressor body, openings of certain shape and size are opened. One for suction, called intake port; the other for exhaust, called exhaust port. Air inlet Detailed analysis of the working process of the screw air compressor: when the rotor rotates, the groove space between the sun and moon rotors is the largest when it turns to the intake end wall opening. At this time, the groove space of the rotor is connected with the intake port. When the air is completely discharged during the exhaust, when the rotor reaches the intake port, the external air is sucked in and enters the grooves of the sun and moon rotors along the axial direction. When the gas fills the entire groove, the rotor intake end face rotates away from the intake port of the housing, and the air in the groove is closed. Compression Detailed analysis of the working process of the screw air compressor: at the end of the suction, the sun and moon rotor teeth will be closed with the casing, and at this time the gas will no longer flow out of the groove. The meshing surface gradually moves to the exhaust end. The groove space between the meshing surface and the exhaust port gradually decreases, and the air in the groove is compressed and the pressure is increased. Exhaust gas Detailed analysis of the working process of the screw air compressor: when the meshing end face of the rotor turns to be connected with the exhaust port of the housing, the compressed gas begins to be discharged until the tooth tip and the meshing surface between the groove move to the exhaust end face. At this time, the meshing surface between the sun and moon rotors and the exhaust port groove space is 0, that is, the exhaust process is completed, and at the same time, the meshing surface between the rotor and the intake port of the casing The length of the grooves reaches the longest, and the intake process is carried out again.
