Abstract

The invention discloses a solar phase change heat storage drying device for Chinese medicinal materials and a drying method. The thermal device is a solar heat collection and heat storage device using phase change materials as heat storage working medium. A heat exchange tube is pre-embedded in the heat storage medium of the solar heat collection and heat storage device. One end of the heat exchange tube It is connected with the drying chamber, and the other end is connected with the blower. While meeting the drying temperature and humidity requirements of the traditional Chinese medicinal materials, the invention retains the original ingredients and medicinal properties of the medicinal materials.

Description

technical field [0001] The invention belongs to the field of solar heat utilization, and relates to a low-temperature multi-stage Chinese medicinal material drying system and a drying device for solar energy phase change heat storage. Background technique [0002] Affected by the COVID-19 epidemic, traditional Chinese medicinal materials have received widespread attention, and the demand for traditional Chinese medicinal materials represented by Lianhua Qingwen Granules has been rising all the way. In the preparation process of these traditional Chinese medicines, the drying of Chinese medicinal materials is a key link, that is, the shelf life is extended through dehydration treatment, while retaining the original ingredients and medicinal properties of the medicinal materials. However, some Chinese herbal medicines will lose their efficacy if they exceed a certain temperature, so temperature control during the drying process is very important. Therefore, the high-efficienc...
