A double cone dryer is a dryer that integrates mixing and drying. It is equipped with a condenser, vacuum pump, and dryer to form a vacuum drying device. It is based on the technology of traditional vacuum rake dryers in China, and is designed to strengthen and improve various materials such as slurry, paste, particle, powder, fiber, etc. The internal structure is simple, easy to clean, and all materials can be discharged. The operation is simple, which can reduce labor intensity and improve the working environment (if solvent recovery is not required, the condenser can be omitted). At the same time, due to the rotation of the container itself, the material also rotates but there is no accumulation of material on the container 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, with good quality. Can be applied to the drying of materials in industries such as pharmaceuticals, chemicals, food, dyes, etc. Complies with GMP requirements. The double cone dryer uses a stirring screw belt to rotate and lift the material, and heat transfer media such as hot water, thermal oil, steam, etc. are simultaneously introduced into the conical jacket.

The double cone dryer is a rotary tank with a double cone shape. Under vacuum, steam or hot water is introduced into the jacket for heating, and the heat comes into contact with wet materials through the inner wall of the tank. The water vapor evaporated after absorbing heat from wet materials is pumped out through a vacuum exhaust pipe through a vacuum pump. Due to the vacuum state inside the tank, and the rotation of the tank causing the material to constantly flip up and down, inside and outside, the drying speed of the material is accelerated, the drying efficiency is improved, and the goal of uniform drying is achieved.

The drying speed is fast, usually only a few seconds to a dozen seconds, with the characteristic of instant drying. The temperature of the droplets during the drying process is relatively low, making it particularly suitable for drying thermosensitive materials, which can maintain the color, aroma, and taste of the materials. To prevent wall sticking in the drying tower, this device is equipped with a special structure, effectively eliminating the phenomenon of product wall sticking. The unique finished product air supply system separates the dried finished product from the hot and humid air inside the system in a timely manner, avoiding the possibility of moisture absorption or agglomeration of the dried finished product. The boiling point of the material solution under vacuum decreases, which increases the heat transfer driving force of the evaporator. Therefore, a certain amount of heat transfer can save the heat transfer area of the evaporator; The heat source for evaporation operation can be low-pressure steam or boiling steam; The evaporator has low heat loss and can be disinfected before drying. There is no impurities mixed in during the drying process, which meets GMP requirements; The use of a condenser can effectively recover solvents from materials.
