Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dryer material stirring, in particular to a screw belt vacuum dryer with pre-stirring structure. BACKGROUND

[0002] A vacuum dryer is a device that performs material drying in a low-pressure (vacuum) environment. Its working principle is to extract air inside the device, allowing the material to be heated in a vacuum environment, thereby reducing the evaporation temperature of the material. This method not only reduces the thermal damage of heat-sensitive materials, but also significantly improves drying efficiency. It is commonly used in pharmaceutical, chemical, food and other industries, and is particularly suitable for materials that need to be dried at low temperatures, such as pharmaceuticals, fruits and vegetables, chemicals, etc. Through the vacuum environment, the drying process of the material can be more uniform, and the drying time is shorter.

[0003] The pre-stirring mechanism on the vacuum dryer can effectively improve the uniformity and drying efficiency of the material. The pre-stirring mechanism can reduce the agglomeration of the material by stirring the material in advance, avoiding incomplete drying of the material due to accumulation or uneven distribution during the drying process. At the same time, stirring can also accelerate heat transfer, making the drying process more balanced and efficient, and improving overall production efficiency.
