Roots water ring vacuum unit as vacuum precooler

Roots water ring vacuum unit is composed of Roots vacuum pump and water ring vacuum pump. The vacuum degree that a single water ring pump can reach is 3300pa. If you want to reach higher vacuum degree requirements, it is necessary to equip roots pump so that it can pump at a higher speed. Roots water ring vacuum unit as a vacuum precooler in the use of time demand of vacuum degree and pumping speed requirements are relatively high, so in the selection of time must be based on the actual situation of the ratio. 

In a cubic reactor, 1 / 3 of cooked meat is required to be placed in the reactor, and the temperature of cooked meat is about 90 ℃. The temperature of cooked meat should be reduced to about 20 ℃ by vacuumizing. The required time is less than or equal to 30 minutes. The transpiration of steam is 20kg every 30 minutes under the condition of vacuum negative pressure.

In the selection of such vacuum units, the need to pay attention to the amount of gas in the reaction, the vacuum requirements for cooling and other factors, so as to correctly select roots water ring vacuum unit and then reach the intention of vacuum precooling.
