Description

Technical Field

[0001] The utility model relates to the technical field of dryers, and particularly relates to a cloth feeding device and a microwave vacuum low-temperature liquid dryer. Background Art

[0002] Vacuum continuous belt dryers are a type of drying equipment that is widely used. They are widely used in industries such as food, pharmaceuticals, and chemicals. The heat source of existing vacuum continuous belt dryers is media such as steam, superheated water, and heat transfer oil, and supporting infrastructure such as steam is required. Its heat transfer method mainly relies on conduction. The heating plate transfers heat to the track, and then the track transfers heat to the material, with a low heat transfer coefficient, seriously affecting the drying efficiency. For heat-sensitive materials (such as traditional Chinese medicine powders), due to the limitation of the temperature upper limit, the temperature of the heating medium needs to be maintained at a low temperature to prevent damage to the internal molecular structure of the product to be evaporated, etc. Therefore, its drying efficiency will be even lower. Therefore, technical personnel have developed microwave vacuum low-temperature drying equipment, which can evaporate the moisture in the product to be dried at a low temperature, thereby achieving the drying purpose.

[0003] In order to improve the drying efficiency of drying equipment, multiple belt conveyors are often arranged in the cavity of the drying equipment. However, how to evenly distribute liquid cloth on each belt conveyor has become an urgent problem to be solved. Summary of the Invention
