Problems solved by technology

However, because the traditional process is a manual intermittent operation, the labor intensity is high, and the quality is difficult to guarantee, especially when it involves the drying process of traditional Chinese medicine extracts. The traditional vacuum box drying and spray drying have long cycles and low output. , low efficiency, high energy consumption, and the use of manual handling during the drying process makes the traditional Chinese medicine very susceptible to bacterial infection. It can be seen that the production method is relatively backward, which greatly restricts the development of my country's traditional Chinese medicine pharmaceutical industry

Embodiment 1

[0034] For the heat-sensitive material, it is first stirred in the batching mixer 101, and then sent to the batching pot 102, and the heat-sensitive material is heated by adjusting the temperature-regulating device 104 of the batching pot jacket to the heat treatment level, according to different process requirements , the heating temperature can be between 20 and 50°C; then the heat-sensitive material is sent to the drying belt drive by the single-screw 103 pump, and the heat-sensitive material is evenly spread on each layer of the drying belt at a certain speed through the distributor and the distribution nozzle 201, the uniform thin layer is generally 0.5 ~ 2mm thick, according to the properties of different heat-sensitive materials, adjust the drying belt drive motor 202 to adjust the translational speed of the drying belt 201; at this time, the vacuum degree in the drying belt drive -0.09Mpa (800pa~500pa), when the heat-sensitive material is conveyed to the upper part of t...

Embodiment 2

[0036]For the biological preparation, it is first stirred in the batching mixer 101, and then sent into the batching pot 102, and the biological preparation is frozen by adjusting the temperature adjustment device 104 of the batching pot jacket to the cooling treatment level, and the cooling temperature is 0~ Between -5°C; afterward, the single-screw 103 pump sends the biological preparation to the drying belt transmission device, and spreads the biological preparation evenly on the drying belt 201 that each layer moves at a certain speed through the distributor and the distributing nozzle. The uniform thin layer is generally 0.5-2mm thick, and the translational speed of the drying belt 201 can be adjusted by adjusting the drying belt drive motor 202 according to the properties of different biological agents; at this time, the vacuum degree in the drying belt drive device is -0.09Mpa (800pa ~500pa), when the biological agent is transported to the upper part of the temperature-a...

Abstract

The invention comprises a charging device, a drying belt driving device and a vacuum plant. The charging device includes a charger mixer, a dosage pot and a single-screw pump mounted one by one. The drying belt driving device is disposed in an enclosed vacuum chamber and has several layers of drying belts with the driving device inside. The vacuum plant includes a vacuum distributor and vacuum pipelines.

Description

technical field [0001] The invention relates to an automatic continuous belt dryer for vacuum low temperature freezing. Background technique [0002] Traditional Chinese medicine preparations are national treasures in my country's pharmaceutical industry, and their curative effects have attracted worldwide attention. However, because the traditional process is a manual intermittent operation, the labor intensity is high, and the quality is difficult to guarantee, especially when it involves the drying process of traditional Chinese medicine extracts. The traditional vacuum box drying and spray drying have long cycles and low output. , low efficiency, high energy consumption, and the manual handling in the drying process makes the traditional Chinese medicine very susceptible to bacterial infection. It can be seen that the production method is relatively backward, which greatly restricts the development of my country's traditional Chinese medicine pharmaceutical industry. How...
