Technical Field
[0001] The utility model relates to the field of energy-saving cold-drying devices, in particular to an energy-saving cold-drying device capable of recovering cold energy. Background Art
[0002] A refrigerated dryer, also known as a freeze dryer, primarily uses a refrigerant to exchange heat with the gas to be dried (such as compressed air), removing moisture from the gas by lowering its temperature. This process typically includes pre-cooling, condensation, drainage, and reheating to effectively dry the gas.
[0003] During operation, traditional cold drying systems generate a large amount of cold air, which is often directly discharged into the environment, resulting in significant energy waste. Furthermore, the cooling, compression, and condensation processes also consume significant amounts of electricity, further increasing operating costs. With rising energy prices and growing environmental awareness, reducing the energy consumption of cold drying systems and improving their efficiency has become a pressing issue. During the cold drying process, traditional systems are unable to control the flow of cold and hot air inside, leading to internal heating, uneven cooling, and concentrated thermal stress within the equipment. Because the placement frame of traditional cold drying systems is fixed, it cannot be customized to the size and shape of the items being dried. This prevents some items of unusual shapes or sizes from being effectively placed, reducing the versatility and adaptability of the equipment. After prolonged use, dust, dirt, and residue easily accumulate inside the housing. Failure to effectively clean the interior of the housing compromises the sanitation of the cold drying system and may even cause secondary contamination of the dried items.
[0004] In response to this technical problem, the present application proposes an energy-saving cold-drying device that can recover cold energy. Utility Model Content
