Description

Technical Field

[0001] The utility model relates to the technical field of vacuum drying ovens, in particular to a novel vacuum drying oven. Background Art

[0002] The vacuum drying oven is specially designed for drying heat-sensitive, easily decomposable and easily oxidizable materials. It can maintain a certain vacuum degree in the working room during operation and can be filled with inert gas. In particular, some items with complex ingredients can also be dried quickly. An intelligent digital temperature regulator is used for temperature setting, display and control. Vacuum drying ovens are mostly used for medium and small trial production or heat treatment of packaging materials.

[0003] When the existing vacuum drying box is used to dry articles, the moisture inside the articles evaporates quickly, but the moisture is not discharged from the drying box in time. When the articles are completely dry, some water droplets still remain on the inner wall of the drying box. When the drying plate is taken out, the articles on the surface are easily in contact with the inner wall of the drying box, causing the articles to be dampened again, affecting the drying effect. The height of the existing drying rack cannot be adjusted, resulting in the inability to fully utilize the internal space of the drying box. Therefore, a new vacuum drying box is needed to solve the above problems. Utility Model Content

[0006] Preferably, the absorbent cotton is in contact with and connected to the inner end surface of the drying box, and the absorbent cotton is made of polyester fiber foam, which has good water absorption and air permeability.

[0007] Preferably, the support frame is located at the lower end of the absorbent cotton, and the support frame is a honeycomb structure, so that water vapor can pass through the support frame and be absorbed by the absorbent cotton.

[0008] Preferably, the support frame is slidably connected to the drying box so that it can be taken out for cleaning.

[0009] Preferably, the top of the sliding rod is rotatably connected to a screw rod, the bottom of the sleeve is provided with a screw hole, the screw rod is inserted into the screw hole and threadedly connected thereto, and a spherical level is provided at the center of the drying rack, and the height of the legs is adjusted by rotating the screw rod.

[0010] Preferably, the top of the sliding rod is rotatably connected to a screw rod, the bottom of the sleeve is provided with a screw hole, the screw rod is inserted into the screw hole and threadedly connected thereto, and a spherical level is provided at the center of the drying rack, and the height of the legs is adjusted by rotating the screw rod.

[0011] Preferably, a pulley is provided at the bottom of the slide rod.

[0012] Preferably, three sides of the side end surface of the drying rack are provided with guard edges to prevent items from sliding off.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model arranges a defogger frame on the inner end surface of the drying box to absorb the water droplets remaining on the inner wall of the drying box into the absorbent cotton, thereby preventing the items on the surface from easily contacting the inner wall of the drying box when taking out the drying plate, causing the items to be dampened again, thereby improving the drying effect.
