Hot air circulating oven for medicinal materials

Abstract

The invention provides a hot air circulating oven for medicinal materials. The hot air circulating oven comprises an oven, wherein a placing platform is arranged in the oven and is arranged on the inner wall of the oven through sliding tracks at two sides; the oven is provided with an air heater; a movable track is arranged between the air heater and the inner wall of the oven; the air heater moves left and right through a moving device arranged on the movable track; and two sides of the upper end surface of the placing platform are provided with detecting devices through which the position of the air heater on the movable track is controlled. The medicinal materials are dried through the oven, the movable track and the moving device drive the air heater to move left and right, and furthermore, the medicinal materials are dried on a fixed point by virtue of hot air; the residual heat is recovered by using a heat recovery device, so that resource waste is avoided, and the drying uniformity of the medicinal materials is improved; and a dehumidifying device is arranged for dehumidifying the inside of the oven, so that the drying efficiency is increased.

Description

technical field [0001] The invention relates to the field of preparation of traditional Chinese medicines, in particular to a medicine hot air circulation oven for drying medicines. Background technique [0002] At present, when manufacturing traditional Chinese medicine, it is necessary to dry the medicinal materials to ensure that the medicinal materials can be used in the next process. At present, when drying medicinal materials, conventional ovens are usually used. The heating of the products is not uniform enough during drying, and when drying a small amount of products, it is still necessary to open a large oven, resulting in waste of resources. Therefore, it is particularly important to solve the problem of uneven heating and waste of resources when the medicinal materials are dried. Contents of the invention [0003] The purpose of the present invention is to provide a medicinal material hot air circulation oven for drying the medicinal material. The medicinal mat...

Problems solved by technology

[0003] The purpose of the present invention is to provide a medicinal material hot air circulation oven for drying the medicinal material. The medicinal material is dried through the oven, and the hot air blower is driven to move left and right through the moving track and the moving device, and then the medicinal material is dried with hot air at a fixed point. And the remaining heat is recovered through the heat recovery device, which solves the problem of uneven heating and waste of resources when the medicinal materials are dried
