Description

An Improved Solar Drying Device

technical field

The invention relates to the technical field of solar energy, in particular to an improved solar drying device.

Background technique

Chinese herbal decoction pieces are Chinese herbal medicines that have been processed and processed according to the theory of traditional Chinese medicine and traditional Chinese medicine processing methods, and can be directly used in Chinese medicine clinics. This concept shows that there is no absolute boundary between Chinese herbal medicines and Chinese herbal decoction pieces. The traditional Chinese medicine slices (including cut sections, blocks, petals) processed at the place of origin, the original herbal decoction pieces, and the sliced (based on the processing at the place of origin) and roasted decoction pieces, the first two types of management should be regarded as Chinese herbal medicines, but only according to The theory of traditional Chinese medicine is understood as decoction pieces in formulas and preparations, while the concept of decoction pieces in the sense of management should be understood as the finished product that is further cut and roasted from the clean medicinal materials processed in the place of origin according to the needs of deployment or preparation, which is called traditional Chinese medicine. Decoction pieces, Chinese medicine decoction pieces are one of the three pillars of China's traditional Chinese medicine industry. They are a necessary traditional weapon for clinical syndrome differentiation and treatment of traditional Chinese medicine. They are also important raw materials for Chinese patent medicines. Their unique processing theories and methods all embody the profound wisdom of ancient Chinese medicine. With the continuous improvement and maturity of its processing theory, it has become an important means of clinical disease prevention and treatment in traditional Chinese medicine. However, there is no good design for the drying equipment of Chinese herbal pieces. In order to solve the above problems, the existing patent announcement number A kind of drying device is announced for the patent of CN105353301A, but does not have material turning effect, and drying effect is relatively poor.
