Drying device for traditional Chinese medicine preparation

Abstract

The invention discloses a drying device for traditional Chinese medicine preparation. The drying device comprises a frame, a drying drum and a screening box, wherein the drying drum and the screening box are arranged in an inner cavity of the frame; a feeding inlet is formed in the center of a top plate of the frame; the drying drum is rotatably arranged on the upper portion of the inner cavity of the frame; the drying drum is provided with a feeding and discharging port; a hot air box is installed on the exterior of the frame and connected with a hot air pipe, a rotation shaft arranged on the end face of the front side of the drying drum is designed to be hollow, and the hot air pipe penetrates through the rotation shaft from the axis of the rotation shaft to stretch into the drying drum and then extend; the screening box is located under the drying drum, and an air suction inlet is formed in the left side of a top plate of the screening box; a dehumidifying box is installed on the portion, corresponding to the air suction inlet, of the top of the screening box and connected with an exhaust fan through a pipeline, the exhaust fan is connected with an air pipe, and the air pipe is connected with the hot air box. According to the drying device, medical materials are heated uniformly, and then the drying effect is guaranteed; meanwhile, reutilization on heat can be completed, and therefore energy conservation and environment protection are achieved.

Description

technical field [0001] The invention relates to the field of preparation of traditional Chinese medicines, in particular to a drying device for preparation of traditional Chinese medicines. Background technique [0002] Processing of traditional Chinese medicinal materials refers to the primary processing of medicinal plants or medicinal animals in the place of origin. Chinese herbal medicine, Chinese medicine is mainly composed of plant medicine (root, stem, leaf, fruit), animal medicine (viscera, skin, bone, organ, etc.) and mineral medicine. Because herbal medicines account for the majority of traditional Chinese medicines, Chinese medicines are also called Chinese herbal medicines.

Problems solved by technology

[0004] Chinese medicine slices need to be dried during the preparation process. At present, the most widely used method is to use electric heating to dry Chinese medicinal materials. This method has a good drying effect, but most of the existing drying devices have problems during the drying process. The uneven heating of the medicinal materials leads to the unsatisfactory drying effect; at the same time, the dried medicinal materials carry more heat, and most of the heat is lost to the air to cause waste, resulting in low energy utilization
