Abstract

The invention provides a vacuum drying oven, and belongs to the field of drying devices. The drying oven which can conduct vacuumizing in the heating process is provided for the problem that because in the prior art, a drying oven cannot conduct the vacuumizing operation during heating, a series of inconvenience is caused. According to the main scheme, A cooler is arranged on an exhaust pipeline, and meanwhile a humidity sensor is arranged to monitor the humidity in the drying oven; on the basis of the scheme, the vacuum degree is precisely controlled by regulating the vacuum degree at any time; and meanwhile, humidity is monitored and regulated in real time, and therefore the drying efficiency can be improved, and energy can be saved.

Description

technical field [0001] The invention belongs to the field of drying equipment, and in particular relates to a vacuum drying oven. Background technique [0002] The vacuum drying oven is specially designed for drying heat-sensitive, easily decomposed and easily oxidized substances. When working, it can maintain a certain degree of vacuum in the working room and can fill the interior with inert gas, especially for some items with complex components. Fast drying, using intelligent digital temperature regulator for temperature setting, display and control. [0003] The existing vacuum drying oven needs to be evacuated before being used, and then heated and dried; this can prevent the heated air from being sucked into the vacuum pump, causing the pump temperature to be too high and resulting in abnormal operation. But in reality, the moisture in the wet material changes from liquid to gas, which will reduce the vacuum degree; at the same time, when the humidity is too high, the ...
