The spiral stirring vacuum drying furnace developed by our company is a specialized equipment for drying granular materials. The granular material to be processed is placed in a drying furnace and continuously contacted with the inner wall of the furnace through spiral stirring to obtain the required heat energy for drying. The stirring continuously exposes the granular material to the evaporated water in the furnace space, which is then discharged from the furnace by a vacuum pumping unit. After such a short period of processing, very dry particles can be obtained. This method is an advanced drying treatment method, and the developed equipment is also advanced. As a result, we obtained a national patent (patent number: 7）
