A method for softening Chinese medicinal materials before slicing

Abstract

The invention belongs to the processing field of traditional Chinese medicine decoction pieces, particularly relating to a method for softening a traditional Chinese medicinal material before slicing. According to the method for softening the traditional Chinese medicinal material before slicing, complete infiltration of water into the drug can be realized, water supply volume in softening of the traditional Chinese medicinal material is reduced, production water is saved, and substance loss amount in the softening process of the traditional Chinese medicinal herbs is reduced. According to the method for softening the traditional Chinese medicinal material before slicing, superiorities of two ways, namely, pressure-reduced cold soaking and pressure-boosted cold soaking, are combined, special equipment is not needed, production site is saved, heating and special pressure boosting and reducing equipment are unnecessary, a common vacuum packaging machine and common air compression equipment are only necessary, so that the production cost is low.

Problems solved by technology

[0002] In the traditional method of softening Chinese medicinal materials before slicing, the water for softening the medicinal materials cannot be completely absorbed by the medicinal materials, resulting in the loss of some water-soluble components without being absorbed by the water, resulting in a decrease in the content of the labeled ingredients in the slices after cutting compared with that of the medicinal materials. In actual production, it is very difficult to make the medicine penetrate water, especially the soaking softening method and soaking softening method cannot achieve "drug penetration", the water consumption in production is also large, and a special softening production site is required; Modern softening of traditional Chinese medicine before cutting includes vacuum heating and softening method, decompression cold soaking softening method, and pressurized cold soaking softening method, all of which require professional equipment. Heating and pressurizing equipment are used, which consumes a lot of energy and production input. The cost of equipment is high, and heating and softening is not suitable for medicinal materials whose active ingredients are unstable when exposed to heat and contain volatile ingredients; both pressurized cold soaking and decompression cold soaking require special equipment, and the investment in production equipment is high. Another disadvantage is that the production Chinese herbal medicines are enclosed in a rigid container. If the container is filled with softening water, the medicinal materials will be over-softened and the water content will be too high. The cut pieces will not be easy to dry, and will also cause the loss of water-soluble components. The medicinal materials are not softened uniformly, and when the decoction pieces are cut, there are many fragments and fragments. It is more difficult to improve the rigid container, because decompression cold soaking requires a certain degree of vacuum to remove the air in the gaps between the medicinal materials, and it is easy to penetrate into the tissue of the medicinal materials. Therefore, a rigid container must be used; pressurized cold soaking uses equipment to press water into the tissue of medicinal materials, and rigid equipment must also be used. Although the two methods can increase the softening speed, neither of the two types of equipment can solve the problem of allowing the medicinal materials to meet their needs. The problem of uniform distribution of softened water on the surface of medicinal materials, and the problem of water volume control in the softening process and consistent softening of medicinal materials did not follow the softening principle of traditional Chinese medicine preservation and drug penetration.
