[0001] The utility model relates to the technical field of dryers, in particular to a dryer with a preheating function. Background Art

[0002] A dryer is a mechanical device that uses heat energy to reduce the moisture content of materials. It is used to dry objects. The dryer heats the material to vaporize the moisture (generally water or other volatile liquid components) in order to obtain solid materials with a specified moisture content.

[0003] According to a disclosed disc dryer with a preheating function (publication number: CN 219756870 U), the device is provided with a feed hopper on the top of a protective cylinder, and a preheating chamber connected to a steam connecting pipe is provided at the position where the protective cylinder is connected to the feed hopper, as well as a fixed partition rotating inside the preheating chamber, so that the exhaust gas after being utilized by the drying disc can be directly discharged into the preheating chamber to directly heat the feed hopper, thereby preheating the material inside the feed hopper.

[0004] However, the device heats the feed hopper and then transfers the heat to the material through the feed hopper. The heat transfer through the feed port will cause heat loss. At the same time, the material will pass through the feed hopper quickly, resulting in less heat received by the material, which in turn leads to poor preheating effect on the material.
