Introduction to the operating procedures of the rotary vacuum dryer

A rotary Vacuum Dryer is a commonly used Dryer. When the drying process is performed, the inside of the dryer is in a vacuum state, which is heated by heat transfer oil, hot water or steam into the jacket, and is in contact with the wet material in the box. The vaporized water after the wet material absorbs heat is pumped through the vacuum exhaust pipe through the vacuum pump, and the thermal efficiency is very high. The operation of the rotary vacuum dryer should also be carried out according to certain operating procedures.

Rotary vacuum dryer

1. Check before starting: Before starting, it is necessary to check whether the position of the filter in the tank rises, whether the filter meets the technical requirements, and whether there is an industrial filter cloth.

2. Close the feed and discharge ports. Remove the cap of the feed tube and attach the feed tube.

3. Turn on the vacuum pump, when a certain degree of vacuum is reached, insert the feeding tube into the powder, suck it into the tank by vacuum, and feed the material according to the standard that the bulk density of the material does not exceed 40% of the total volume, and the material cannot be mixed with hard lumps shape.

4. After feeding, remove the feeding pipe and install the cover of the feeding pipe to ensure the sealing performance.

5. Open the valve of the vacuum pipeline to make the tank reach a certain degree of vacuum. Turn on the host start button to rotate the container around the horizontal axis at the appropriate speed.

6. Open the jacket heating steam inlet valve to heat and dry the material. It should rotate intermittently during drying to reduce the material agglomeration.

7. According to the operating conditions, when it is confirmed that the drying process of the materials in the tank has been cut off, cut off the steam and vacuum pipeline valves, and then slowly cool the jacket cooling water and materials to an appropriate temperature. to rotate the cylinder to the desired angle.

9. Turn off the vacuum pump, open the valve of the vacuum line, and open the exhaust valve of the vacuum system, so that the cylinder can be connected to the atmosphere. Open the discharge cover to discharge.

10. Clean the remaining material box in the box and close the discharge cover to prevent dust from entering the cylinder. Remove the cyclone and clear out the fines.

The operation process of the rotary vacuum dryer is also very important, which is an important part of the operation. The above is a brief introduction to the operation steps of the rotary vacuum dryer. The correct operation steps allow us to better understand.
