Novel medicine drying machine

Abstract

The invention provides a novel medicine drying machine which is capable of controlling the proportion of dried water and controlling the drying temperature and capable of preventing medicine products from deforming in the drying process. The novel medicine drying machine comprises a combustion chamber and a drying chamber. A hot air pipe is arranged in the combustion chamber. One end of the hot air pipe is connected with an air blower, and the other end of the hot air pipe communicates with an air inlet of the drying chamber. Air outlet holes are formed in the peripheral wall of the drying chamber. Each air outlet hole comprises a main air outlet hole body and multiple auxiliary air outlet hole bodies. The auxiliary air outlet hole bodies are formed in the periphery of each main air outlet hole body at even intervals. The corresponding auxiliary air outlet hole bodies are circumferentially formed. According to the novel medicine drying machine, by reasonably designing the air outlet holes, in the early stage of the drying process, the main air outlet hole bodies and the auxiliary air outlet hole bodies are all opened, the maximum air outlet capacity is achieved in the drying process, and at the moment the water vapor evaporation spillover of water is maximum; and in the later period of the drying process, the main air outlet hole bodies are closed, water vapor overflows slowly from the auxiliary air outlet hole bodies, and thus the water loss speed of the medicine products is controlled precisely, and the deformation of the medicine products is prevented.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine pharmaceutical equipment, in particular to a novel medicinal material drying machine. Background technique [0002] The raw materials of Chinese medicinal materials are mostly plant roots, stems and leaves, which are usually dried to remove excess water before making medicine. At present, most of the dryers used for medicinal materials use electric dryers with heating wires or dryers heated by oil tanks. These dryers have relatively complicated structures and high costs, and the heat source directly faces the raw materials of Chinese medicinal materials, which is easy to burn Chinese herbal medicine raw materials, causing economic losses. In order to solve this problem, a dryer that dries medicinal materials with hot air has been developed. The structure of this dryer includes a combustion chamber and a drying chamber. There is a hot air pipe in the combustion chamber, and on...

Problems solved by technology

However, for dryers with this structure, the air outlet is generally fixed, and the amount of hot air in the combustion chamber is generally difficult to accurately control, so it is difficult to adjust the drying temperature in the drying chamber; and the functions of the air outlet also include Take away moisture, and some precious medicinal materials will cause product deformation with the rapid loss of moisture, so it is necessary to reasonably control the moisture content of medicinal materials to prevent product deformation
