Cyclic heating drying cabinet

Abstract

The invention belongs to medical equipment and provides a cyclic heating drying cabinet. The cyclic heating drying cabinet comprises a cabinet body, wherein the cabinet body is sequentially provided with a first drying layer, a second drying layer and a third drying layer from top to bottom; each of the first drying layer, the second drying layer and the third drying layer is provided with a drying chamber and a detection chamber, a wavy drying conveyor belt is arranged in the drying chamber, heating pipes are arranged on the drying conveyor belt, an air blower is mounted at an inlet of the drying chamber, a humidity sensor is mounted at an outlet of the drying chamber and connected with a single chip microcomputer, a discharge port is formed in the detection chamber, and an electronically operated gate at the discharge port is connected with the single chip microcomputer; the discharge port of the first drying layer is connected with the inlet of the second drying layer through a spiral feeding belt I, and the discharge port of the second drying layer is connected with the inlet of the third drying layer through a spiral feeding belt II. The cyclic heating drying cabinet has the benefits as follows: gradual heating of medicinal materials is facilitated, heating drying efficiency and quality of the medicinal materials are improved, and resources and cost are saved.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a circulating heating drying oven. Background technique [0002] The medicinal materials need to be processed and dried before the finished products are sold and manufactured, but the traditional drying and processing of medicinal materials is convenient, especially for some Chinese herbal medicines, the fine powder in the medicinal materials is likely to fly around and cause pollution when blast drying is used. Moreover, in the traditional drying process of medicinal materials, it is impossible to detect the degree of drying of medicinal materials at any time, so that it is impossible to confirm whether the medicinal materials are qualified and whether they need to continue drying. If the medicinal materials are overdried, the efficacy of the medicinal materials will be reduced, and resources will be wasted. Contents of the invention [0003] In view of the above-men...
