Amount, is prevented effectively from loss of material, with high practical value.
What the purpose of this utility model was realized in：A kind of vacuum drying oven, including casing, set on described roof box
Bleeding point is put, air inlet is set on described box bottom, described cabinet front arranges safety door, arranges in described casing
There is multilamellar coil pipe, on described coil pipe, place drip pan, support bar, described casing top and casing are set between described coil pipe
Bottom is respectively provided with flow distribution plate, and passage is uniformly arranged on described flow distribution plate, and described bleeding point passes through pipeline and surge tank phase
Even, described air inlet connects gas drier, described gas drier connection nitrogen tube and air hose by pipeline,
Described nitrogen tube is connected with nitrogen pot.
The distance between described two-layer coil pipe is 15-20 centimetre.
Pressure vacuum meter is provided with described safety door, temperature measuring equipment on described safety door, is provided with, it is described
Safety door and casing between rubber washer is set.
This utility model produce beneficial effect be：Drying device is set on the pipeline of air inlet, to into baking oven
Gas is dried, it is to avoid the moisture in air enters into the quality that product is affected in baking oven, the quality of material is effectively ensured, together
When casing inner top and bottom arrange flow distribution plate, make the air-flow Uniform Flow in baking oven, effectively avoid the material quilt in baking oven
The loss of material that air-flow blows out drip pan and causes, with high practical value.
