What is the use of air compressor in food processing plant
Compressed gas for refrigeration and gas separation:The gas is liquefied by compression, cooling, and expansion, used for artificial refrigeration (refrigeration and air conditioning), such as ammonia or Freon air compressor. The compression pressure of more than 8 ~ 12 kg / cm2, this type of air compressor is usually a "refrigerator" or "ice machine"". In addition to the liquefied gas for gas mixture, in the separation device, the components were separated, qualified to get all kinds of gas lip reading. For example, the pure oxygen, pure nitrogen, pure xenon, krypton, argon, helium and other rare gases can be obtained after the air separation of the air compressor.
Air compressor used in food factory is mainly reflected in the following aspects:1, compressed air as power:A total of all kinds of pneumatic driving machinery, Sullair air compressor accessories pneumatic tool exhaust pressure is 7 to 8 kg / square centimeter, used to control instrumentation and automation equipment, the pressure is about 6 kg / cm2, automatic doors and windows, opening and closing, the pressure is between 2 and 4 kg / cm2, the pharmaceutical industry, stir in wine brewing industry the pressure of 4 kg / cm2, weft in jet loom blowing pressure is 1 ~ 2 kg / cm2, in the large diesel engine starting pressure is 25 ~ 60 kg / cm2, wells fracturing pressure of 150 kg / cm2, the "two law" about oil pressure 50 kg / cm2, high pressure blasting mining pressure is about 800 kg / cm2, the defense industry in the pressure of the compressed air as its power. The ups and downs of the submarine, the torpedo shooting and driving, as well as salvage of the wreck, and so on, are compressed air with different pressure for its power.
The air is compressible, and the air compressor is used to make the mechanical work to reduce the volume. Compressed air is an important source of power. And other than energy, it has the following obvious characteristics: clear and transparent, convenient transportation, no harmful special performance, no fire danger, not afraid of overload, in many unfavorable environment, the air on the ground everywhere, inexhaustible.
Synthesis and polymerization of compressed gases;In the chemical industry, the gas is compressed to high pressure, often beneficial to synthesis and polymerization. For example, the synthesis of ammonia nitrogen, hydrogen and carbon dioxide to synthesize methanol, carbon dioxide and ammonia synthesis of urea, etc.. Chemical industry, such as high pressure polyethylene pressure of 1500 ~ 3200 kg / cm2.4, compressed gas hydrogenation of oil refining:In the petroleum industry, the hydrogen is heated by artificial means, which is pressurized to react with the oil, so that the hydrocarbons can be broken down into the light components of hydrocarbons, such as the light of the heavy oil, the hydrogenation of lubricating oil, etc..
