1Working principle: SZG double conical revolving vacuum drier has double conical rotating cylinders. Under the state of vacuum in the cylinder, it passes steam of hot water into the jacket to heat. The heat will be contacted with damp raw material through inner wall. The evaporated steam after the raw material absorbing heat will be exhausted through vacuum pump. Because the inner of cylinder is in vacuum state and the cylinder makes raw material turn over up to down, and from inner to outer. The drying speed in increased, and the drying efficiency is raised, and the purpose of uniform dry can be reached. Features: This is a new style dryer integrating mixing and frying as a whole. It is equipped with condenser and vacuum pump to consist of vacuum drying device (if the solvent does not recover, the condenser may not be used). The design of this machine is advanced, and its inner structure is simple. So it is very convenient to clean, and the raw material can be discharged fully, and its operation is very simple. It can reduce labor strength and improve working environment. When the cylinder is rotating, the raw material is rotated as well, and the wall of cylinder cannot be accumulated on the wall. Its coefficient of thermal transmission is high and the drying speed is high. Not only it can save energy, but also the raw material can be dried fully and uniformly, and the quality of product is high. It can be used widely for foodstuff industry, pharmaceutical industry and chemical industry. it is in conformity with the requirements of GMP. Scope of applications: The machine is suitable for vacuum mixing and drying of powder and granule raw materials of pharmaceutical industry, chemical industry and foodstuff industry. Particularly, it is suitable for raw materials that have the following requirements: 1) Thermal sensitive raw materials that cannot withstand high temperature 2) Raw materials that are easy to oxidize but with dangers 3) Raw materials that the solvent and toxic gases are needed to recover 4) Raw materials that have special requirements for crystal shape 5) Raw materials that have special requirements for the content of residual volatile Notice in order: 1) Hearing has 3 ways: steam, hot water, heat conduction oil 2) When order, please indicate the temperature of raw material to be undertaken, or the operation temperature of drier in order to choose or provide suitable heat source for you 3) When dry viscous raw material, our factory will design special stirring device in the chamber 4) The auxiliary parts of vacuum drying system can be supplied and installed by our factory. Please indicate when order 5) If having special requirements, our factory can also design, manufacture and install as per requests 6) The cost of complete equipment should be increased in accordance with the needs drying machine
