The main unit of the double cone rotary vacuum drying machine is a double cone tank body. Under vacuum, steam or hot water can be introduced into the jacket to process the inside of the tank. The heat is transferred to the wet material through the inner liner, causing the moisture in the wet material to vaporize. The low-speed motor drives the tank body to rotate, causing the material to continuously move up and down, flipping inside and outside, and replacing the heating surface. At the same time, water vapor is continuously pumped out through the vacuum exhaust pipe, accelerating the drying rate of the material and ultimately achieving the goal of uniform drying.
The double cone rotary vacuum drying machine mainly has the following characteristics:
1. Due to being dried under vacuum, it has a higher speed at lower temperatures, which is twice as fast as general drying equipment, saving energy and high heat utilization. It is particularly suitable for drying heat sensitive materials and easily oxidizable materials.
2. Closed and dry, with no leakage or pollution of the product, suitable for strong stimulation and the dryness of toxic and harmful materials
3. The material is mixed and dried during rotation, and can be dried to a very low moisture content (less than or equal to 0.5%) with good uniformity, suitable for different material requirements
4. The equipment has a compact structure, occupies a small area, is easy to operate, reduces labor intensity, and saves labor.
5. Users can choose between stepless speed regulation (1-10 revolutions per minute) and stepped speed regulation (rated speed 6-10 revolutions per minute), making it easy to adjust and adapt to different requirements.
The double cone rotary vacuum drying machine is suitable for vacuum drying and mixing of powder and granular materials in industries such as medicine, food, and chemical engineering, especially for materials with the following requirements:; Heat sensitive materials that cannot withstand high temperatures; Easy to oxidize and hazardous materials; Materials that require the recovery of solvents and toxic gases; Require materials with extremely low residual volatile matter content; Materials with specific requirements for crystal shape; Require thorough and uniform mixing of materials.
