A vacuum rake dryer is a type of drying equipment that uses vacuum technology to remove moisture from materials. It consists of a cylindrical vessel with a heating jacket and a rotating rake inside. The material to be dried is placed on the bottom of the vessel and heated by the jacket. The vacuum creates a low-pressure environment that reduces the boiling point of the water in the material, causing it to evaporate more easily. The rotating rake stirs the material to ensure even drying. The dried material is then removed from the vessel.
The working principle of a vacuum rake dryer is to use the continuous stirring of a rake stirrer in a vacuum environment to evaporate and extract the moisture in the material, thereby achieving the purpose of drying.
Specifically, the working process of a vacuum rake dryer is as follows:
- Put the material to be dried into the dryer, close the lid of the dryer to form a closed space.
- Start the vacuum pump to extract the air in the dryer to create a vacuum environment.
- The heating device starts to heat, transfers the heat to the material, causing the moisture in the material to evaporate.
- The rake stirrer starts to stir, constantly turning the material to evenly evaporate the moisture.
- The evaporated moisture is extracted by the vacuum pump, cooled by the condenser, and then discharged outside the dryer.
- When the moisture content of the material reaches the set requirements, stop heating and stirring, turn off the vacuum pump, open the lid of the dryer, and remove the dried material.
The vacuum rake dryer has the advantages of fast drying speed, good drying effect, and low energy consumption, and is widely used in the chemical, pharmaceutical, food, and other industries.
