Spiral belt vacuum dryer is a multifunctional fully enclosed vertical vacuum drying equipment that integrates drying and mixing. Its drying efficiency is 3-5 times that of the same specification "double cone rotary vacuum dryer".

Internal heating of the screw belt increases the overall heating area of the equipment by 30%.
The spiral belt vacuum dryer can achieve the effect of bottom-up circulation stirring and obtain forced heat transfer performance. When the material loading rate is between 30% and 100%, 100% heating utilization can be achieved. Suitable for mixing and drying delicate materials.
Fully enclosed system, free of foreign matter contamination, high cleanliness, especially suitable for mixing and drying sterile biological products, drugs, etc.
The gap between the spiral belt vacuum dryer and the container wall is small, which can effectively prevent materials from sticking to the surface of the wall.
Adopting a small angle conical cylinder structure, the unloading speed is fast, clean, and does not accumulate material.
The tank body and discharge valve can achieve online cleaning (CIP) and online sterilization (SIP).
The equipment has a compact structure, smooth operation, good sealing, no lubrication leakage, easy operation, and long service life.

This machine is driven by an explosion-proof motor and a FAF series parallel helical gear reducer, which drives the spiral belt agitator to rotate. The animal material rotates along the conical cylinder wall and is lifted from bottom to top. After reaching the highest point, the material flows automatically to the center of the vortex and returns to the bottom of the conical cylinder by gravity and inertia. The series of processes forcibly heats the material inside the conical cylinder, causing it to diffuse, convective, shear, displace and mix with each other, resulting in irregular reciprocating motion of the material in all directions, completing high-frequency heat exchange between the material and the spiral belt and cylinder wall surface, and achieving the effect of heating and drying in a short time.
