Efficient drying equipment for preparation of traditional Chinese medicine decoction pieces

Abstract

The invention discloses efficient drying equipment for preparation of traditional Chinese medicine decoction pieces. The efficient drying equipment comprises a drying oven, a plurality of supporting columns are symmetrically and fixedly connected to the bottom side wall of the drying oven, a drying cavity is formed in the drying oven, an air inlet flow dividing cavity and an air outlet flow gathering cavity are formed in the two ends of the drying cavity correspondingly, and an air inlet pipe communicating with the air inlet flow dividing cavity is fixedly connected to the end, close to the air inlet flow dividing cavity, of the drying oven. According to the efficient drying equipment, an electrified thin resistance wire is adopted as a drying assembly, the characteristic that the electrified thin resistance wire emits heat and emits red light after being electrified is utilized, and heating and drying treatment is carried out on the traditional Chinese medicine decoction pieces mainly by means of a heat radiation mode; compared with a traditional hot air drying mode and a high-temperature environment drying mode, the mode has the characteristics that the heat utilization rate is higher, more energy is saved, and the drying efficiency is remarkably improved; and in the drying process, the drying cavity is in a negative pressure state, so that water is easier to evaporate, then the drying work of the traditional Chinese medicine decoction pieces can be efficiently completed, the drying speed is high, and the drying effect is good.

Description

technical field [0001] The invention relates to the technical field of preparation of decoction pieces of traditional Chinese medicine, in particular to a high-efficiency drying equipment for preparation of decoction pieces of traditional Chinese medicine. Background technique [0002] Decoction pieces refer to traditional Chinese medicines that are processed and processed according to the needs of traditional Chinese medicines for formulas, or can be directly used in Chinese medicine clinics. When preparing Chinese medicine decoction pieces, it is necessary to first soak the Chinese medicine decoction pieces in water to soften them for slicing. After slicing, since the decoction 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 the preparation of Chinese herbal medicines is in use, two methods of hot air drying and high...

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
