A kind of Chinese medicine drinking tablet for preparation and efficient drying equipment

Abstract

The invention discloses a high-efficiency drying device for preparing Chinese herbal decoction pieces. The two ends of the oven are respectively provided with an intake air distribution chamber and an air outlet concentrating chamber, and an air inlet pipe communicating with the air intake distribution chamber is fixedly connected to one end of the oven close to the air intake distribution chamber. The invention adopts the energized thin resistance wire as the drying component, and takes advantage of its characteristic of heating and glowing red after energization, and mainly uses heat radiation to heat and dry the Chinese herbal medicine pieces. Compared with the traditional hot air drying and high temperature environmental drying methods In other words, the heat utilization rate is higher, the energy saving is more, and the drying efficiency has been significantly improved. During the drying process, because the drying chamber is in a negative pressure state, the water is easier to evaporate, so that the drying of the Chinese herbal medicine pieces can be efficiently completed. Work, not only the drying speed is fast, but also the drying effect is good.

Description

technical field [0001] The invention relates to the technical field of preparation of traditional Chinese medicine pieces, in particular to a high-efficiency drying device for the preparation of traditional Chinese medicine pieces. Background technique [0002] Decoction pieces refer to traditional Chinese medicines that are processed and processed according to the needs of traditional Chinese medicines for formulation, or Chinese medicines that can be directly used in the clinical practice of traditional Chinese medicine. When preparing decoction pieces of traditional Chinese medicine, it is necessary to soak the decoction pieces of traditional Chinese medicine in water to soften them for slicing. After the slicing is completed, since the pieces contain moisture, they need to be dried. In order to improve the production and processing efficiency, the drying method is generally used to dry them. [0003] When the existing drying equipment for preparing Chinese herbal medicin...

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: when the existing drying equipment for the preparation of Chinese herbal medicines is in use, two methods of hot air drying and high-temperature drying are mainly used to dry the Chinese herbal medicines. During hot air drying, since it is used to dry the Chinese herbal decoction pieces with the help of circulating high-temperature hot air, it is necessary to preheat the fresh air, and then heat the Chinese herbal medicine decoction pieces through cold and heat exchange, which involves two heat transfers. The heat loss is relatively high. When drying at high temperature, because it is also dried by means of cold and heat exchange, and in order to avoid excessive humidity in the drying chamber due to water evaporation during the drying process and thus inhibit water evaporation, continuous drying is required. Supplementary dry fresh air comes in, and dry fresh air needs to be preheated, so it also has the disadvantages of high heat loss and insufficient energy saving. At the same time, the drying efficiency is low and it is not convenient for small-scale drying operations
