When the work is put into the vacuum dryer, it should be evacuated first and then heated up and heated. The purpose of this is to avoid the pressure generated by the expanding gas from bursting the tempered glass of the observation window. If you heat up and then vacuumize, then When the heated air is pumped out by the vacuum pump, the heat will be brought to the vacuum pump, which will cause the temperature rise of the vacuum pump to be too high, which may reduce the efficiency of the vacuum pump. The vacuum pressure gauge produces an indication error. So need to do this, stay away from potential dangers. Therefore, we need a normal operation process, first vacuuming and then heating up, which is also beneficial for the extended use time of the machine. When the vacuum dryer is in operation, start the stirrer first, add the material to be dried, close the feeding port, and at the same time pass steam for heating. The pressure of the heating steam is generally 0.2~0.4Mpa.
In normal use, you also need to pay attention. In addition to the standardized operation, you also need to do daily maintenance work. When the vacuum drying is completed, you need to take out the debris left in the machine, and the filter bag is often cleaned, so that The purpose is to make the filter and vacuum pipeline unblocked. If possible, it is necessary to regularly check whether the motors, pressure gauges, etc. are normal, and frequent inspections can prevent danger.
