The Heat Pump Dryer's Dehumidification Process

How does the air-energy heat pump dryer dehumidify? 

It mainly depends on the temperature in the dryer room.If the temperature is less than 38 degrees Celsius, it is recommended to use a general refrigeration dehumidification unit. The working temperature is 5–38 degrees Celsius. When the temperature exceeds 40 degrees Celsius, it will automatically shut down for protection. If the temperature is between 38 and 50 degrees, it is recommended to use a special dehumidification unit for the drying room, which has strict restrictions on the temperature.

In order to reduce energy consumption, heat pipe technology has been added to the drying market in recent years, and the effect is very good. If a heat pipe heat exchanger is added to recover the energy in the exhaust air, That is, through the heat pipe heat exchanger, the sensible heat in the exhaust air is absorbed and released in the supplementary fresh air.

The heat pump dryer advantage

1.Suitable for a wide range of temperatures;

2.Remove the humid air in the drying room through ventilation.

3.Supplement fresh air with dry and hot air;

4.Good energy-saving effect;

5.Low equipment investment;

How to dehumidify the heavy humidity?

A dehumidifier with super dehumidification capacity is undoubtedly the best way to remove moisture in the drying room and can also control the indoor humidity; however, the temperature in the general drying room must be 40°C or even above 50°C; therefore, it is necessary to use a special high-temperature dehumidifier for the drying room to dehumidify the drying room normally, which can greatly speed up the drying time, thereby effectively improving the drying efficiency. The utilization rate of the drying room and the quality of drying.

Generally, the working environment temperature of the refrigerated dehumidifier is 5–38 °C, and the dehumidifier will be automatically protected and shut down if it exceeds 38 °C. However, in the material heat pump dryer and drying room, the indoor temperature generally exceeds 40°C. Therefore, ordinary refrigerated dehumidifiers cannot work in this environment. The current drying method in general enterprises is to force the hot and humid air in the drying room to be discharged outside through the fan. In this way, the heat in the room is also discharged outside.

For the needs of drying rooms, heat pump dryers, air energy dryers, high-temperature heat pump dryers, energy-saving dryers, and special high-temperature dehumidifiers for drying rooms (suitable for indoor temperatures higher than 38°C and lower than 55°C) It can be widely used in heating, curing, drying, and dehydrating materials and products in pharmaceutical, chemical, food, light industry, heavy industry, and other industries. Such as: wood, dried fruits, edible fungi, agricultural and sideline products, paper products, raw materials, crude drugs, Chinese herbal medicines, powders, granules, pigments, dyes, dehydrated vegetables, dried melons and fruits, sausages, plastic resins, electrical components, baking paint, etc.
