Heat Pump Dehumidifier with 5-99% RH Adjustable Humidity and 22KG/Hour Dehumidification for Low Temperature Drying

Our low-temperature dehumidifying fruit drying oven utilizes advanced low dew point dehumidification technology, designed to simulate the physical characteristics of northern winter's northwest wind. Through two-stage dehumidification, the system generates cold, dry air with low temperature and humidity—an environment that maximizes preservation of materials' original shape, color, and flavor during drying. This makes it particularly ideal for heat-sensitive fruits, aquatic products, and Chinese herbal medicines that require low-temperature, slow drying.

This heat pump low-temperature dehumidifying fruit drying oven provides heating, cooling, and dehumidification for the drying chamber through an efficient operational cycle:

• Moist, hot air from the drying chamber enters the system through the return air duct
• Air passes through the high-temperature side of the heat exchanger for initial temperature reduction
• Second cooling stage via surface cooler brings air close to dew point temperature
• Final cooling through evaporator triggers condensation and dehumidification
• Condensed moisture is collected and drained away automatically
• Dehumidified air transforms into low-temperature, low-humidity drying air
• Heat exchange warms the air while further reducing humidity
• Conditioned air is distributed back into drying chamber to continue the cycle

Widely used for drying and extracting cell liquid from various materials including:

• Roses, chrysanthemums, honeysuckle
• Gardenia, jasmine, American ginseng
• Cistanche and many other Chinese herbal medicines

• Precise temperature control: 15-30°C adjustable range
• Accurate humidity control: 5-99% RH adjustable
• Efficient dehumidification: Average 22KG/hour at 25°C and 70% RH
• Automatic adjustment of fan air pressure and speed based on conditions
• Negative pressure cold-air circulation drying mode ensures uniform drying
• Closed room low temperature dehumidification maintains stable quality
• Energy efficient and environmentally friendly operation

The high temperature heat pump consists of compressor, condenser, throttling device and evaporator. The refrigerant absorbs air heat from the evaporator, transforming from low pressure liquid to steam, then pressurized into high temperature steam by the compressor. In the condenser, the refrigerant releases heat and condenses into high pressure liquid. The throttling device reduces pressure and temperature, completing the cycle that transfers low temperature heat to high temperature medium.
