Abstract

The invention discloses a vacuum microwave drying oven for powder drying. The vacuum microwave drying oven for the powder drying is characterized by comprising a drying oven; the drying oven comprises a feed inlet and a discharge outlet; a microwave generator, a vacuum generator and a stirring device which are connected with a PLC (Programmable Logic Controller) device are arranged inside the drying oven. The vacuum microwave drying oven for the powder drying has the advantages of saving energy due to the fact that microwaves can be used to dry and meanwhile to sterilize; enabling powder preparations to be well dried under a low temperature condition due to the added vacuum generation device which vacuumizes the drying oven; reinforcing the drying effect due to the added stirring device which can coordinate dispersing of the powder under the vacuum state and fully scatter and stir the powder preparations; being rapid in drying speed, small in energy consumption efficiency ratio, uniform in material drying effect and not easy to get damp.

Description

technical field [0001] The invention relates to a drying oven, in particular to a vacuum microwave drying oven for powder drying. Background technique [0002] Some powder preparations such as traditional Chinese medicine powder and pharmaceutical preparations need to be dehydrated and dried in the subsequent process of preparation. Usually, the dried powder is dried by microwaves. For example, the patent 201320120751. The moisture in the material evaporates and is taken away. However, this kind of dryer has a cumbersome process, is more complicated to use, and cannot specifically dry powder preparations, and cannot accurately control parameters, and the drying effect is mediocre. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a vacuum microwave drying oven for powder drying, which can efficiently and quickly dry powder preparations. [0004] In order to achieve the above object, ...
