Description

Technical Field

[0001] The utility model relates to the technical field of powder drying, in particular to a powder multi-layer drying structure. Background Art

[0002] Existing dryers are generally divided into three types: belt type, drum type and box type. Among them, the belt type dryer mainly focuses on continuous drying of the production line and is usually not suitable for drying different raw materials. The drum dryer is also for a single raw material, and during the dehumidification process, water vapor occasionally returns to the raw material after the dryer temperature drops.

[0003] Box drying is a widely used drying equipment in food production. The drying temperature of box dryers occasionally appears in two forms. For example, the temperature inside the drying chamber is uniform, which may cause some raw materials to be over-dried when the raw materials are different; for example, the temperature inside the drying chamber is uneven, and the temperature near the heating component inside the dryer is high, and the temperature far away from the heating component is low, resulting in the temperature difference being difficult to control, and it is impossible to effectively dry different raw materials. Even for the same raw materials, drying quality deviations are prone to occur; therefore, how to optimize the drying method of the dryer is worth studying. To this end, the utility model proposes a multi-layer drying structure for powder materials to solve the above problems. Utility Model Content
