A vacuum drying oven

Abstract

The invention discloses a novel vacuum drying oven which belongs to the technical field of material drying. A drying cabinet is mounted inside a main box body; a plurality of drying chambers are arranged inside the drying cabinet; a heating assembly is mounted on the back surface of the drying cabinet; a vacuum compression assembly is mounted on a position, inside the base, below the drying cabinet; the bottom end inside the each drying chamber is equipped with a clearing assembly; and the position, at one side of the main box body, above the base is equipped with a control switch. The novel vacuum drying oven is scientific and reasonable, and is safe and convenient in use; a way of vacuum-pumping the inner parts of the drying chambers and performing runner heating is utilized, so that material heating efficiency is improved; indirect heating is performed inside the drying chambers, so that pollution on materials in a drying process is avoided; moreover, vacuum-pumping gas is filtered,so that pollution, on environment, by pumped gas is also avoided, and environmental sanitation is effectively protected; and meanwhile, through chamfering transition treatment on the drying cabinet,clearing of the drying cabinet is more convenient.

Description

technical field [0001] The invention relates to the technical field of material drying, in particular to a vacuum drying oven. Background technique [0002] With the continuous development of society and the continuous advancement of science and technology, the medical level of the society is also constantly improving, and the improvement of medical level is inseparable from the production and manufacture of medicines. Drying is an essential step, and the existing drying devices for pharmaceutical production have the following disadvantages in use: [0003] 1. When the existing drying ovens for pharmaceutical production are used, the drying efficiency of pharmaceutical raw materials is low, which increases the drying time of pharmaceuticals and reduces the output of pharmaceutical production; [0004] 2. When the existing drying oven for pharmaceutical production is in use, the inside of the drying oven is heated unevenly, resulting in uneven drying of the medicine, which w...

AI Technical Summary

Problems solved by technology

[0003] 1. When the existing drying ovens for pharmaceutical production are used, the drying efficiency of pharmaceutical raw materials is low, which increases the drying time of pharmaceuticals and reduces the output of pharmaceutical production;

[0004] 2. When the existing drying oven for pharmaceutical production is in use, the inside of the drying oven is heated unevenly, resulting in uneven drying of the medicine, which will affect the drying effect of the medicine, cause inconsistent humidity of the raw material of the medicine, and affect the normal production of the medicine;

[0005] 3. It is inconvenient to clean the inside of the medicine drying box when the existing drying box for medicine production is in use, so that when different medicines are dried inside the same drying box, it is easy to cause pollution to the medicine;
