Today I would like to introduce a vacuum pump, which is sold in Syria. Interested friends can read on.
Liquid ring vacuum pump on food
There are many foods which are not suitable for vacuum packing. Such as crisp food, lumpy food, deformed greasy food, sharp edges or higher hardness of food will Pierce the packaging bag, etc., after the food through vacuum ventilation packaging, the air pressure inside the bag is greater than the air pressure outside the bag. Can effectively avoid food crushing deformation, does not affect the appearance of packaging bags and printing decoration. Vacuum gas packing is nitrogen, carbon dioxide, oxygen or two or three gas mixture into the water ring vacuum pump.
Nitrogen is an inert gas, which fills the bag with positive pressure to prevent the air from entering the bag and maintain the food. Its carbon dioxide can be dissolved in various fats or water, resulting in weak acidity of carbonate, which has the activity of inhibiting microorganisms such as fungi and corrosive bacteria. Its oxygen content can inhibit the growth and reproduction of anaerobic bacteria, adhere to the novelty and color of fruits and vegetables, high concentration of oxygen content can produce new. Under its working pressure, the liquid ring vacuum pump shall be able to discharge all gases generated in the process of vacuum equipment. Understand the composition of the extracted gas, the gas does not contain condensable steam, particle dust, corrosion, etc. In the selection of vacuum pump, it is necessary to know the gas composition, and choose the right pump for the pumped gas.
If the gas contains steam, particles and corrosive gases, it should be considered to install condenser, dust collector and other auxiliary equipment in the inlet pipe of the pump. What are the environmental effects of oil vapor from liquid ring vacuum pumps? If the environment is not allowed to be polluted, you can choose the oil-free vacuum pump or discharge the oil vapor to the outdoor. Whether the vibration of liquid ring vacuum pump during operation has any influence on the process and environment. Do not allow, should choose no vibration pump or take anti – vibration measures. Vacuum pump price, operation and maintenance costs.
Oil pollution requirements for vacuum equipment. If the equipment is strictly oil-free, you should choose all kinds of oil-free pumps. If the requirements are not strict, you can choose a pump, plus some measures to prevent oil pollution, such as the addition of cold trap, baffle, oil collector, can also meet the requirements of vacuum cleaning.
The vacuum packing of liquid ring vacuum pump is a method of putting the articles into airtight container. This kind of packing can prevent moisture from entering the packing container, and can also avoid moisture in sealed moisture-proof packing and dew when the temperature drops.
Liquid ring vacuum pump adopts vacuum packing, and attention should be paid to prevent excessive vacuum. Ordinary grains and processed goods can be packed in vacuum. Vacuum packaging not only prevents or reduces oxidation, discoloration and flavor of grains, but also inhibits the growth of certain fungi and bacteria.
The vacuum packaging of liquid ring vacuum pump not only controls the external temperature and sterility, but also controls the gas environment suitable for grain to achieve the ideal preservation purpose. The main methods are mechanical extrusion and suction tube degassing. Liquid ring vacuum pump, in any way, is to take the air out of the package, and then heat seal. Its main characteristics are: reduce the oxygen content of the bag, inhibit the growth and development of fungi and bacteria, control the deterioration of grain, achieve the purpose of preservation and quality. In addition, vacuum packaging, but also can resist mechanical pressure, reduce vibration, conducive to long-distance transportation and sales. The main function of liquid ring vacuum pump is not only to protect oxygen and quality, but also to protect pressure, gas and freshness. It can maintain the original color, aroma, taste, shape and nutritional value of food for a long time.
