Chinese herbal medicine drying technology

Abstract

The invention discloses a Chinese herbal medicine drying technology. The drying technology involves a cut-off collator, a plate-strip type drying chamber, a forced cooling chamber, a circulating fan,a dehumidifier, a heat pump and a slicing collator. The drying technology comprises the following steps that the heat pump utilizes air as a heat source to prepare heat and sends the heat into the plate-strip drying chamber, heat is reserved through the circulating fan to circularly heat and dry materials, meanwhile, the heat pump utilizes the cold-hot symbiosis characteristic of the heat pump toinput cold generated during drying and heating into the forced cooling chamber, the dried materials are cooled, moisture absorption and moisture regain are avoided, the crispy effect is achieved, andquick packaging is facilitated. According to the drying technology, the process is simple, the combined use is convenient, the applicability is wide, the modular combined design is adopted, differenttemperature gradients can be controlled according to a material drying curve, the graded drying process is achieved, and the loss of effective components of Chinese herbal medicine raw materials in the dewatering and drying process is reduced to the maximum extent; and the problem of operation of a universal automatic and modular combined pretreatment unit for dewatering and drying multiple varieties of Chinese herbal medicine raw material is solved.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical production technology, and in particular relates to a drying technology applied to Chinese herbal medicinal materials. Background technique [0002] There are many kinds of raw materials of raw Chinese herbal medicine with different specifications. There are rhizome medicinal materials with large proportion, grass stems and grass leaves with light weight, branch or bark medicinal materials, and fruit medicinal materials, etc. The pharmaceutical production plant They need to be dehydrated and dried in the pre-treatment unit before they can be stored or used in the subsequent process; due to the complexity of the original raw materials of Chinese herbal medicines, the dehydration and drying process of the materials has a wide range of temperature changes in the drying process and different cycle lengths. The active ingredients of the material are easily lost. At present, such materials are u...
