Vacuum refrigeration of vacuum unit

Vacuum unit is made up of Roots vacuum pump and water ring vacuum pump. The vacuum degree of a single water ring pump is 3 300 Pa. If you want to achieve higher vacuum degree, you must equip Roots pump, which can also increase the pumping speed.

Vacuum unit in the use of vacuum pre-cooler when the vacuum and pumping speed requirements are relatively high, so the selection must be based on the actual situation proportioning. Vacuum unit is used as vacuum precooler in cooked meat processing to describe: cooked meat needs to be placed in a cubic reactor for 1/3 of the temperature of cooked meat is about 90 degrees Celsius, the temperature of cooked meat needs to be reduced to 20 degrees Celsius through the purpose of vacuum, the required time is less than or equal to 30 minutes, every 30 minutes in vacuum negative The evaporation of steam is 20kg under pressure.What-is-liquid-ring-vacuum-pump

Because of the high pressure resistance of the molecular booster pump, the former stage pump can easily be in a high flow state; while the molecular booster pump has a high suction pressure, which reduces the pre-pumping burden of the former stage pump. Molecular booster pump can work in 100-50Pa, the former pump from the atmosphere to this pressure, basically obey the pressure every time to reduce an order of magnitude, so the unit can have a high pumping efficiency. To simplify the high vacuum unit and cancel the roots pump is another advantage of the molecular booster pump.high-temperature-problem-of-vacuum-pump
