Description

Technical Field

[0001] The utility model relates to the technical field of drying, in particular to an adjustable blast drying box. Background Art

[0002] The blast drying oven is a device used to dry materials. Its main principle is to use a fan to blow hot air into the box, and evaporate the moisture in the material through circulating heating to achieve a rapid drying effect. The blast drying oven is widely used in food processing, chemical, pharmaceutical, electronics and other industries.

[0003] Adjustable blast drying oven generally refers to drying equipment with adjustable parameters such as temperature, humidity, wind speed, etc. By adjusting these parameters, the drying process can be controlled more accurately to meet the drying requirements of different materials. Adjustable blast drying oven is suitable for a wider range of drying needs, improving the flexibility and versatility of the equipment.

[0004] The patent "Electric Constant Temperature Blast Drying Oven" (publication number CN114234595A, hereinafter referred to as prior art 1) discloses a drying oven. By controlling the second servo motor, the output shaft of the second servo motor drives the clamping assembly to rotate, and then drives the product to be dried on the clamping assembly to rotate, which is conducive to improving the uniformity of heating and drying, and at the same time can improve the drying speed. By controlling the second driving member, the gap between two adjacent trays can also be adjusted, which is convenient for workers to place the product to be dried, and improves the convenience of operation. The tray is provided with air holes, which is conducive to air flow through the tray, improving the uniformity and efficiency of drying; however, the air supply of the blower used in prior art 1 is insufficient, and each blower is powered separately for driving, and the adjustment is unchanged. When it needs to work at the same time, it needs to be turned on one by one, which is inconvenient when a relatively large space is required; and the air supply of a single blower is relatively small, which can only be applied to working conditions with less materials or smaller spaces, and cannot fully cover working conditions with more materials or larger spaces.
