Many industries now use freeze dryers, which is a method of freezing water-containing substances into a solid state, and then sublimating the moisture from the solid state into a gas state to remove the moisture and preserve the substance. The maintenance of each equipment can be divided into daily maintenance and periodic maintenance. In order to ensure the normal operation of the machine and the quality of the air, it is necessary to maintain and maintain the machine.
　　(1) Daily maintenance items
　　1. Check whether the condenser on the back of the machine is clean before starting to avoid poor heat dissipation.
　　2. Check whether the safety device is reliable before starting.
　　3. Check whether the working pressure and working current are normal after the machine runs for 10 to 20 minutes.
　　4. After 10 minutes or 20 minutes of running with compressed air, check whether the automatic drain is draining.
