However it is worth mentioning that some problems should be paid attention to in the use of vacuum dryernbspFor example the environmental requirements of vacuum dryer should be considered such as temperature relative humidity voltage and the influence of strong vibration strong electric magnetic field and corrosion gasIn order to ensure the normal operation of vacuum drying it is suggested to add filter between vacuum box and vacuum pump to prevent wet gas from entering vacuum pump resulting in vacuum pump failure.

In addition due to the relatively high surface temperature of the spray dryer during operation or after shutdown please do not touch cyclone separator atomizer exhaust fan air duct and other parts directly by handAt the same time when the temperature of the spray drying tower does not drop to room temperature please do not enter the towerWhen the oxygen does not reach a certain concentration it is strictly forbidden to open and check the spraydrying machine door otherwise it is easy to cause oxygen deficiency.
