[0002] In the initial processing of biological resources, in order to increase the shelf life or production needs, drying is basically a necessary process. However, the current drying equipment mostly uses a single humidity control method to dry materials. This single control There are many problems in the wet method, and the practicability and applicability are poor

[0003] In the existing drying technology, when the drying method is mostly used in the drying process, the humid and hot gas in the drying room is directly discharged out of the drying room, and there is no waste heat recovery function, resulting in large temperature loss and heat loss in the drying room, increasing equipment capacity. consumption; the loss of volatile value components reduces the quality of materials

[0004] When the existing drying technology adopts a separate dehumidification method during the baking process, the moisture in the drying room will decrease in the later stage of drying, so that the latent heat value will become smaller and smaller, increasing energy consumption, and when the drying equipment is insufficient or drying some When it is necessary to quickly remove a large amount of moisture from the material, it is difficult to meet the drying demand only by dehumidification

[0005] Chinese patent 201710727891.4 discloses a drying heat pump system with dual modes of air-energy open dehumidification and closed dehumidification. Materials are dried through two humidity control modes. On the barn, there is no waste heat recovery and secondary heat recovery function, resulting in large heat loss and high energy consumption; when the closed dehumidification is running, due to the lack of an evaporator, if the temperature in the barn is too high, the barn cannot be heated. The internal temperature can be adjusted accurately in real time, and the drying heat pump system disclosed in this patent can only operate the dehumidification mode and the dehumidification mode alone, and cannot operate the two modes at the same time, which is difficult to meet special baking needs
