The Furnace Wind Dehumidifier Dryer, inspired by the natural "Furnace Wind" phenomenon, significantly enhances the dehumidification and heating capacity of the unit. The unit and wind wall are independently installed, offering greater air volume and lower air resistance. The wind wall size can be customized to meet requirements, providing flexible installation options; available in 13P, 15P, 20P, and 25P models.
Closed-loop Dehumidification Heat Pump Dryer Drying Principle
Closed-loop dehumidifying heat pump dryers are used in the drying process. Their main principle is to use the heat pump compressor to work, repeatedly circulating and heating the hot air inside the drying room, absorbing moisture from the material. While the heat pump evaporator condenses and removes water, it also absorbs heat from the humid air, providing heat for drying and dehumidification. This process repeats, achieving continuous drying of the material.
Closed-loop dehumidifying heat pump dryer, utilizing a patented constant temperature dehumidification technology, significantly enhances dehumidification capacity compared to conventional heat pump dryers. The closed design ensures stable operation at low temperatures with minimal impact from environmental temperatures. It can maintain drying time and effectiveness even in cold and humid regions.
Principle of Heat Pump Dryer
Heat Pump Dryer Principle: The heat pump dryer utilizes the reverse Carnot principle to absorb heat from the air and transfer it indoors, thereby increasing the temperature of the drying room and facilitating the drying of materials with the help of corresponding equipment. The heat pump dryer consists of a compressor—heat exchanger (indoor unit)—throttle valve—heat absorber (outdoor unit)—compressor, and other components, forming a closed-loop system (main unit + drying room).
The refrigerant circulates within the system under the action of the compressor. It undergoes a pressurization and heating process in the compressor (with temperatures reaching up to 115℃), then enters the indoor unit to release the high-temperature heat, warming the air inside the drying room. Meanwhile, it cools down and turns into a liquid state. As it reaches the outdoor unit, the liquid rapidly absorbs heat and evaporates back into a gas state, with the temperature dropping to -20℃ to -30℃. At this point, the surrounding air around the heat absorber continuously transfers heat to the refrigerant. The continuous circulation of the refrigerant accomplishes the transfer of heat from the air to the drying room, thereby heating the air inside.
Heat Pump Dryer Application Range
The heat pump dryer is suitable for a wide range of materials. Materials primarily suitable for drying include those that can withstand temperatures between 20-80°C during the drying process, or those that can tolerate higher temperatures but are more energy-efficient or safer to dry using a heat pump. Materials that have been extensively researched and applied include wood (such as oak), grains, seeds, edible fungi (like mushrooms, wood ear), seafood (such as fresh oysters, scallops), bioactive products (such as cells, enzymes), tea, paper, and more.
