The invention provides a system and a method for drying thick-layer traditional Chinese medicine by the aid of variable-temperature alternate airflow, and relates to the technical field of traditional Chinese medicine drying and storing. The system for drying the thick-layer traditional Chinese medicine by the aid of the variable-temperature alternate airflow comprises a drying chamber, an air supply system and a temperature and humidity detecting system. A left air supply hole and a right air supply hole are respectively formed in the left side and the right side of the drying chamber, and the drying chamber further comprises a left air box, a right air box, a ventilating disc and a material disc; the air supply system comprises an air supply fan, a heater, a temperature control module and an air supply control module. The method for drying the thick-layer traditional Chinese medicine by the aid of the variable-temperature alternate airflow includes forwardly drying the thick-layer traditional Chinese medicine at moderate temperatures; reversely drying the thick-layer traditional Chinese medicine at moderate temperatures; forwardly drying the thick-layer traditional Chinese medicine at high temperatures; reversely drying the thick-layer traditional Chinese medicine at high temperatures, and repeatedly carrying out high-temperature forward drying and high-temperature reverse drying procedures until moisture contents of traditional Chinese medicine materials reach preset moisture contents. The system and the method have the advantage that problems of poor traditional Chinese medicine drying effect and low traditional Chinese medicine drying efficiency at present can be solved by the aid of the system and the method.
Description
technical field [0001] The invention relates to the technical field of drying and storing Chinese medicinal materials, in particular to a system and method for drying thick-layer Chinese medicinal materials with variable temperature and alternating air flow. Background technique [0002] China is the birthplace and largest producer of traditional Chinese medicine. In my country, Chinese herbal medicines have always maintained the traditional model of farmers planting, decentralized storage, and farmer's market operations. The essence of drying Chinese herbal medicines is the complex heat-mass coupling transfer process of Chinese herbal medicines under the action of drying medium, and the moisture content of Chinese herbal medicines is reduced to about 14% during the drying process to facilitate safe storage. Due to the backward drying machinery technology in the pre-treatment process of Chinese herbal medicines after harvesting, the quality of Chinese herbal medicines and t...
