Before the use of the machine, in order to ensure the normal operation of the machine, it is required to do the following performance test:

First, the first to open the vacuum pump circulating water pump cooling water, so that the supply of cooling water.

Two, check the cooling water tank, confirmed that there is water in the tank. Check whether the vacuum gauge in the zero and the pump interface, the four section of the sterilization device interface is the interface, the interface is free of loose dew, check the error, and then carry out the next step.

, first don't turn on the pump vacuum pump, water in four type sterilizer from the flash evaporator cycle to be heating temperature rising can feed.

Four, to open at the same time four type sterilization feeder pump and flash evaporator feed pump, the flash evaporator feed liquid to maintain in the mirror below the median line position, the material liquid level to be stable after the next step work.

Five, open the cooling water circulation system, so that the cooling water level in the cooling water to keep the water level in the cooler line to start the cycle.

Six, open the vacuum pump before the pump, the first vacuum valve and then gradually open the vacuum pump to increase.

Seven, in the process of increasing the vacuum pump, vacuum pump affects the flash device for a feed pump, discharge decreases, liquid level rise must close the fourth section sterilizer feed mouth, stable liquid level. Therefore, the vacuum pump does not have to reach the maximum (0.08).
