Method for preparing traditional Chinese medicine decoction pieces based on freeze-drying technology

Abstract

The invention relates to a method for preparing traditional Chinese medicine decoction pieces based on a freeze-drying technology, a bottom plate, support frames and a dehydration device are included,the support frames are symmetrically mounted at the upper end of the bottom plate, the upper ends of the support frames are of arc-shaped structures, and the dehydration device is mounted between theupper ends of the support frames. The method can solve the problems that when existing equipment dries traditional Chinese medicine decoction pieces, moisture in medicinal materials is removed by adopting a high-temperature baking mode generally; however, high-temperature baking easily causes deformation and inactivity of active substances in the traditional Chinese medicine decoction pieces; meanwhile, the traditional Chinese medicine decoction pieces are easily combined with oxygen in the air to generate oxidation reaction; and when the traditional Chinese medicine decoction pieces are dried by the existing equipment, the traditional Chinese medicinal materials are usually stacked together, and the flaky traditional Chinese medicinal materials cannot be turned over, so that the traditional Chinese medicinal materials are poor in drying effect and low in efficiency, and the processing efficiency of the traditional Chinese medicine decoction pieces is influenced, and the like.

Description

technical field [0001] The invention relates to the field of processing traditional Chinese medicine decoction pieces, in particular to a method for preparing Chinese medicine decoction pieces based on freeze-drying technology. Background technique [0002] Freeze-drying technology is a drying method that freezes medicinal materials in water below the freezing point, turns the water into ice, and then turns the ice into steam under a relatively high vacuum to remove it. Chinese herbal medicines can be frozen in the freezer first, and then dried. It can also be frozen directly in the drying room by quickly evacuating it, and the water vapor generated by sublimation is removed by the condenser. [0003] At present, the following defects usually exist in the preparation and processing of the existing Chinese herbal pieces: 1. When the existing equipment is drying the Chinese herbal pieces, it usually uses high-temperature baking to remove the moisture inside the medicinal mate...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the problem that the existing equipment usually uses high-temperature baking to remove the moisture inside the medicinal material when drying Chinese herbal pieces. Oxygen in the air combines with an oxidation reaction, resulting in the loss of nutrients at all levels in the Chinese herbal medicine pieces, and when the existing equipment is drying the Chinese medicine medicine pieces, the Chinese herbal medicines are usually piled up together, and the flake Chinese herbal medicines cannot be turned over , leading to poor drying effect and low efficiency of Chinese herbal medicines, and affecting the processing efficiency of Chinese herbal medicines, etc.
