Overview
Double cone rotary vacuum dryer is a new type of dryer that integrates mixing and drying. The condenser, vacuum pump, and dryer are matched to form a vacuum drying device. (If the solvent does not need to be recovered, the condenser can be omitted) This machine has an advanced design, simple internal structure, and easy cleaning, and all materials can be discharged. It is easy to operate, which can reduce labor intensity and improve the working environment. At the same time, because the material rotates when the container itself rotates, but there is no accumulation of material on the wall, the heat transfer coefficient is high and the drying rate is large, which not only saves energy but also makes the material dry evenly and fully with good quality. It can be widely used in the drying of materials in the pharmaceutical, chemical, food, dye, and other industries. It meets the "GMP" requirements.
Application range
This machine is suitable for vacuum drying and mixing of powder and granular materials in the pharmaceutical, food, chemical, and other industries, especially for materials with the following requirements:
Thermosensitive materials that cannot withstand high temperatures:
Easily oxidized and dangerous materials;
Materials that require recovery of solvents and toxic gases:
Materials that require extremely low residual volatile content;
Materials that require full and uniform mixing;
Working principle
SZG double-cone rotary vacuum dryer is a double-cone rotary tank. In the vacuum state, steam or hot water is introduced into the jacket for heating, and the heat contacts the wet material through the inner wall of the tank. The water vapor evaporated by the wet material after absorbing heat is pumped away through the vacuum exhaust pipe by the vacuum pump. Since the tank is in a vacuum state, and the rotation of the tank makes the material constantly flip up and down, inside and outside, it speeds up the drying speed of the material, improves the drying efficiency, and achieves the purpose of uniform drying.
Features
When the oil is heated, it adopts automatic constant temperature control, which can dry biochemical products and mineral raw materials. The temperature can be between 20-160℃, and the temperature is within ±2℃.
High thermal efficiency, more than 2 times higher than that of ordinary ovens.
Indirect heating, the material will not be contaminated, which meets the requirements of "GMP". The equipment is easy to maintain and easy to clean.
