Continuous turnover type vacuum drying oven

Abstract

The invention relates to the technical field of medicine powder drying equipment, in particular to a continuous overturning type vacuum drying box. The device comprises a drying oven, a vacuum air extracting pump and a turnover device, the air extracting end of the vacuum air extracting pump is communicated with the interior of the drying oven, and the turnover device is arranged on the drying oven; the overturning device comprises an overturning driving assembly arranged on the drying oven, a grid plate arranged on the overturning driving assembly and a product container detachably connected to the grid plate, the product container is used for storing product powder, a limiting hole is formed in the peripheral surface of the product container in a penetrating mode, and the aperture of the limiting hole is smaller than the particle size of the product powder; the grid plate is contained in the drying oven, and the turnover driving assembly drives the product container to turn over through the grid plate. The vacuum drying box has the function of improving the removal effect of the vacuum drying box on the moisture of the product powder.

Description

technical field [0001] The invention relates to the technical field of medical powder drying equipment, in particular to a continuously turning vacuum drying oven. Background technique [0002] The vacuum drying oven is a device that removes the moisture inside the container by pumping out the air inside the packaging container to achieve a predetermined vacuum degree. The vacuum drying oven is specially designed for drying heat-sensitive, easily decomposed and easily oxidized substances, so it is widely used in dehydration and drying of agricultural and sideline products, health care products, food and medicinal materials, fruits and vegetables, chemical raw materials, etc., low-temperature concentration of chemical products, and removal of crystal water , drying of enzyme preparations, vacuum extraction of Chinese herbal medicines, etc. [0003] refer to figure 1 , is a kind of vacuum drying oven in the related art, and it mainly comprises base 1, oven 2 and vacuum pump ...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that when the product powder is dried in a vacuum drying oven, since the product powder remains stationary for a long time, the internal product powder is prone to agglomeration and locks water, resulting in the internal product powder. Moisture is difficult to evaporate completely
