2023/03/31

1. The vacuum drying oven is mainly a static drying process, and the double-cone rotary vacuum dryer is a dynamic drying process.

2. The material in the vacuum drying box is not moving. In the vacuum state, the moisture inside the material is transformed from liquid to gaseous when heated; the material in the double-cone rotary vacuum dryer is constantly moving, and the moisture in the material Under the heat transfer of the interlayer, the gasification process occurs continuously, and at the same time, the vacuum pumps out the water.

3. The vacuum drying oven is suitable for drying liquid materials, such as the drying of extracts, and the double-cone rotary vacuum dryer is suitable for low-temperature drying of solid materials.



4. During the drying process of the vacuum drying oven, the material is easy to stick to the plate and it is difficult to clean up. The double cone rotary dryer does not have this problem.
