Multi-cavity separated taking type vacuum drying box

Abstract

The invention provides a multi-cavity separated taking type vacuum drying box. The multi-cavity separated taking type vacuum drying box comprises a box body, an electric controller and a vacuum pump. The internal space of the box body is divided into a front material storage cavity and a rear vacuumizing cavity, and a deflation valve and a vacuum joint connected with the vacuum pump are arranged on the rear vacuumizing cavity; the front material storage cavity is evenly divided into four branched cavities, and switch control valves are arranged on the rear side walls of the branched cavities; the branched cavities are communicated with the rear vacuumizing cavity by opening the switch control valve. A temperature and humidity sensor and a vacuum degree sensor are arranged in each branched cavity, and a frame plate which is horizontally arranged and used for containing materials is arranged in each branched cavity and is of a hollow-out structure. The temperature and humidity sensors and the vacuum degree sensors are connected with the electric controller, and the vacuum pump, the deflation valve and the switch control valve are controlled by the electric controller. The multi-cavity separated taking type vacuum drying box has the beneficial effects that the structural design is reasonable, and the materials can be taken and put respectively.

Description

technical field [0001] The invention relates to a multi-chamber separating type vacuum drying oven. Background technique [0002] In the existing technical pharmaceutical industry, various dryers and drying ovens are very important equipment. The raw materials or semi-finished products of medicinal materials must go through the drying process to remove all or part of the water or solvent and meet the humidity requirements of the process before subsequent processing. Therefore, the performance of the drying box determines the drying quality of the medicinal materials; for pharmaceutical and chemical laboratories. In other words, the vacuum drying oven is an indispensable drying equipment, but because there are many varieties studied in the laboratory, the drying time and drying temperature of the products vary greatly, and it is often the case that a variety of materials are stored in a drying oven. At this time, if a material needs to be taken out, the air release valve of ...

The raw materials or semi-finished products of medicinal materials must go through the drying process to remove all or part of the water or solvent and meet the humidity requirements of the process before subsequent processing. Therefore, the performance of the drying box determines the drying quality of the medicinal materials; for pharmaceutical and chemical laboratories. In other words, the vacuum drying oven is an indispensable drying equipment, but because there are many varieties studied in the laboratory, the drying time and drying temperature of the products vary greatly, and it is often the case that a variety of materials are stored in a drying oven. At this time, if a material needs to be taken out, the air release valve of the box needs to be opened to restore the pressure in the whole box to a normal value before opening the box, which will definitely affect the drying effect of other materials in the box
