Abstract

The invention relates to the technical field of dryers, in particular to a hollow type cylinder vacuum drying box. The hollow type cylinder vacuum drying box is provided with a hollow interlayer cylindrical box body. A box cover is arranged at one end of the box body, the box cover is provided with a sealing ring sealed with the box body, a drying frame sliding rail is arranged on the box cover, and a drying frame is connected to the portion above the drying frame sliding rail. A hot water inlet, an extraction opening and a hot water outlet are formed in the outer wall of the box body. The extraction opening is connected with a vacuum pump through a pipeline, and a temperature meter monitoring the temperature in the box and a pressure meter monitoring the pressure in the box are arranged above the box body. The hollow type cylinder vacuum drying box is reasonable in design, the temperature and vacuum degree can be accurately adjusted, the drying rate is high, heat is sufficiently utilized, mixing of impurities can be avoided in the drying process, the static vacuum drying is achieved, and therefore the quality of dried materials cannot be affected.

Description

technical field [0001] The invention relates to the technical field of dryers, in particular to a hollow cylindrical vacuum drying oven used for low-temperature or high-temperature drying in pharmaceutical, chemical, food, light industry, plastic and other industries. Background technique [0002] The vacuum drying oven is specially designed for drying heat-sensitive, easily decomposed and easily oxidized substances. It can flush inert gas into the interior, especially some items with complex components can also be dried quickly. Vacuum drying is the heating and drying of the dried material under vacuum conditions. It uses a vacuum pump to pump air and dehumidify to form a vacuum state in the working room, reduce the boiling point of water, speed up the drying speed, and can dry at a lower temperature. , high drying rate is obtained, the heat is fully utilized, and no impurities are mixed in the drying process. It belongs to static vacuum drying, so it will not damage the sh...
