Problems solved by technology

[0003] The purpose of the present invention is to overcome the disadvantages of uneven drying, unstable drying quality, long drying cycle, and large energy consumption in the prior art, and seek to design and prepare a drying equipment that uses a rotating cylinder as a drying chamber to place quilts. For dry materials, the materials are automatically and evenly turned over in the rotating cylinder with the rotation of the cylinder; a far-infrared energy radiation device or a microwave gen

Abstract

The invention relates to a drying equipment for heat sensitive material with speediness, uniformity, high efficiency and energy saving, comprising rotating cylinder, heating technology of far infrared radiation or microwave generator and vacuum drying technology. The equipment is widely applied in the drying process for multiple materials of industry and agriculture, especially the material with the highest temperature limited rigidly, such as Chinese traditional pill, Chinese medicinal material and several chemical materials with heat sensitivity so on. By the invention, uniform drying is accomplished in lower temperature so as to ensure the quantity of drying production and quickly drying can be accomplished to shorten the drying period, decrease the energy cost in drying process and improve production efficiency.

Description

technical field [0001] The invention belongs to the technical field of material drying, is widely used in the drying process of various materials in production, and relates to a drying equipment for heat-sensitive materials suitable for drying materials with strict restrictions on the maximum temperature allowed in the drying process. In particular, it is a drying equipment that organically combines rotating cylinder, far-infrared energy radiation or microwave generator heating technology and vacuum drying technology. Background technique [0002] Due to the extensiveness and importance of the drying process, humans have invented a variety of drying equipment, such as fluidized bed dryers, tube bundle dryers, paddle dryers, spin flash dryers, moving bed dryers, tunnel dryers, Vacuum dryers, etc., each existing drying equipment has its specific scope of use. However, so far, there is no ideal process for the drying process of materials (hereinafter referred to as heat-sensit...
