Double Tapered Rotary Vacuum drier

Description of Double Tapered Rotary Vacuum drier

Double cone rotating vacuum drier is a new drier that integrates mixing and drying in the one body and equips with condenser and vacuum pump. Therefore the vacuum drier is formed (If the solvent does not recover, the condenser may be not used). The drier is advanced in design, simple in inner structure, easy for cleaning, to discharge all raw materials, convenient in operation, low the strength of labor and improving work environment. Meanwhile raw material is rotating accompanying with the rotating of container; raw materials cannot be accumulated onto the wall of container, so it has high efficiency heat transfer and high speed drying which save energy. Raw materials are dried evenly and have good quality. It can widely apply to dry raw materials of pharmaceutical industry, chemical industry, foodstuff industry, and dyestuff industry and so on. The equipment is in conformity with the requirements of "GMP".

Applications of Double Tapered Rotary Vacuum drier

The drier is suitable for drying and mixing powder or granule raw material of pharmaceutical industry, foodstuff industry and chemical industry and so on. Especially it is suitable for the following raw materials that have special requirements:
1)thermal sensitive raw material that cannot in high temperature;
2)raw materials that are easy to be oxidized or to be dangerous;
3)raw materials in which the solvent needs to recover and there is toxic gases;
4)raw material that have the requirement of containing rather low content of residue volatized materials;
5)raw materials that need to mix evenly and fully.


Principle of Double Tapered Rotary Vacuum drier

Double cone rotating vacuum drier has double cone rotating tank. Under the state of vacuum inside the tank, pass steam or hot water into to jacket for heating. The energy can contact with the damp raw material through the inner wall. The vaporized steam can be pumped out through vacuum exhaust pipe when the damp raw material absorbed heat. Because the inner of tank is in the state of vacuum and the raw material is turned over all the time caused by the rotating of tank, the dry speed of raw material is quickened and drying efficiency is raised too and the purpose of uniform dry can be raised.

Features of Double Tapered Rotary Vacuum drier

When oil is used to heat, use automatic constant temperature control. It can be used for drying biology products and mine. Its temperature of operation can be adjusted from 20~200C and within ±2C.
Compared with ordinal drier, its heat efficiency will be over 2 times;
the heat is indirect. So the raw material cannot be polluted. It is in conformity with the requirement of GMP. It is easy in washing and maintenance.
