working principle
The SZG double cone rotary vacuum dryer is a double cone rotary tank body. In a vacuum state, the tank body is heated by introducing heat transfer oil or hot water into the jacket, and the heat contacts the wet material through the inner wall of the tank body. The water vapor or other gases evaporated from wet materials after absorbing heat are extracted through a vacuum pump and a vacuum exhaust pipe. Due to the vacuum state inside the tank and the continuous up and down, internal and external flipping of the material caused by the rotation of the tank, the drying speed of the material is accelerated, and the drying rate is increased to achieve uniform drying.
characteristic
The double cone rotary vacuum dryer is a new type of dryer that integrates mixing and drying. Combine the condenser, vacuum pump, and dryer to form a vacuum drying device. If solvent recovery is not required, the condenser can be omitted. This machine has advanced design, simple internal structure, easy cleaning, and can discharge all materials, making operation simple. Can reduce labor intensity and improve working environment. At the same time, due to the rotation of the container itself, the material also rotates, but there is no material accumulation on the wall, resulting in a high heat transfer coefficient and a high drying rate. This not only saves energy, but also ensures uniform and sufficient drying of the material, resulting in good quality. It can be widely used for drying in industries such as pharmaceuticals, chemicals, food, dyes, etc.
Application scope
This machine is suitable for vacuum drying and mixing of powder and granular materials in industries such as medicine, food, and chemical engineering, especially suitable for drying required by the following:
※ High temperature thermosensitive materials are not acceptable
Materials that require solvent and toxic gas recycling
※ Easy to oxidize, hazardous materials
※ Materials with requirements for crystalline morphology
※ Materials with extremely low residual volatile matter content are required

Note: For materials with significant volume changes before and after drying, the loading coefficient can be appropriately increased or decreased, and the large loading volume should not come into contact with the bottom of the vacuum tube.
The motor can be equipped with a variable speed motor according to user requirements, with a speed range of 0-6rpm; The above technical parameters are calculated based on a material specific gravity of 0.6g/c m3. If it exceeds this limit, it must be raised when placing an order; If the user needs a pressure vessel certificate, they need to request it when placing an order; If the inner liner material is made of enamel glass, it needs to be specified when placing an order; If the material is flammable and explosive, it must be clearly stated when ordering, otherwise its use is strictly prohibited.
Ordering Notice
There are two forms of heating: hot water heating and heat transfer oil heating.
Please indicate the temperature that the material can withstand or the operating temperature of the dryer when placing an order, so that our factory can select or provide a heat source for you.
When drying viscous materials, our factory will specially design a "copying board" structure inside the tank.
The accessories involved in the vacuum drying system can be provided and installed by our factory for users. Please specify in the order.
Our factory can provide design, manufacturing, and installation services for special requirements raised by users.
