Electric heating type traditional Chinese medicine drying room and drying method

Abstract

The invention discloses an electric heating type traditional Chinese medicine drying room. The drying room comprises a room body and drying equipment arranged in the room body; the room body comprisesa drying room outer wall, a drying room inner wall and a hot air circulation cavity arranged between the drying room outer wall and the drying room inner wall; and a draught fan is arranged on the position, located at the top of the room body, of the drying room inner wall, a first electric heating bar and a second electric heating bar are arranged in the hot air circulation cavity, a hot air pipe communicating with the hot air circulation cavity and the interior of the room body is arranged on the side wall of the drying room inner wall, and the middle part of the room body is provided witha traditional Chinese medicine storage rack. According to the drying room, the electric heating bars are utilized for heating, environment-friendly and cleanness effects are realized, the temperatureis easy to control, and the drying room is convenient to popularize and apply in the industry. Accordingly, the invention further provides a drying method applied to the above electric heating type traditional Chinese medicine drying room.

Description

technical field [0001] The invention belongs to the technical field of processing Chinese herbal medicines, in particular to an electrically heated drying room for Chinese herbal medicines and a drying method. Background technique [0002] The existing drying equipment for the drying room of traditional Chinese medicine uses a fuel burner, which is connected to the hot gas pipe arranged in the drying room of traditional Chinese medicine through a furnace structure, so as to increase the temperature in the drying room of traditional Chinese medicine and achieve the goal of drying. the goal of. However, the oil pipeline using the fuel oil technology is complicated, the oil pressure is unstable for long-distance pressure delivery, the overall combustion equipment occupies a large area, and the fuel oil is not fully burned, the fuel value is low, and the production efficiency is low, so that the temperature of the drying room cannot meet the requirements of the drying process. ...

AI Technical Summary

Problems solved by technology

However, the oil pipeline using the fuel oil technology is complicated, the oil pressure is unstable for long-distance pressure delivery, the overall combustion equipment occupies a large area, and the fuel oil is not fully burned, the fuel value is low, and the production efficiency is low, so that the temperature of the drying room cannot meet the requirements of the drying process. The requirements of the medicine process have caused great difficulties in drying the medicinal materials, or the drying time needs to be continuously increased, or other methods are needed to meet the process requirements.

At the same time, fuel oil also pollutes the environment relatively large. The black smoke generated during incomplete combustion not only pollutes the environment and equipment, but also contaminates medicinal materials, causing great losses.
