Latest company news about Precautions for using refrigerants in fruit and vegetable freeze dryers

Refrigerant is a very important additive when the fruit and vegetable freeze dryer is running, but the following matters must be paid attention to when using it:


① Before the refrigerant, the quality of the refrigerant must be determined, and the refrigerant can be charged only after the quality is no problem. The poor quality refrigerant is very destructive to the compressor and the refrigeration system, which will affect the operation of the refrigeration system at light level, and damage the compressor at worst.


②If the refrigerant is azeotropic, it is not necessary to turn the cylinder upside down and lay flat, and directly charge it into the system; if it is a non-azeotropic refrigerant, consider turning the cylinder upside down and laying flat (that is, the outlet is liquid), but the refrigerant The tank valve i] should be closed as small as possible to avoid the liquid hammer phenomenon of the compressor.


③ Observe the pressure of each pressure gauge, the number of air bubbles on the sight glass and the amount of defrost of the compressor to determine the refrigerant charge.
