Equipment functions and features

Features

1. Multifunctional drying: The unit has four functions: heating, dehumidification, dehumidification and automatic.

2. High efficiency and energy saving. The heat of heating the air in the heat pump dryer mainly comes from the sensible heat and latent heat contained in the warm and humid air discharged from the recovery drying room. The energy that needs to be input is only the power consumption of the heat pump compressor, and the heat pump can consume a small amount of work Taking advantage of a large amount of heat, the SMER (the amount of moisture in the wet material removed by the unit energy consumed) of the heat pump drying device is usually 1.0 ~ 4.0kg/kWh, while the SMER value of the traditional convection dryer is about 0.2 ~ 0.6kg/kWh.

3. Precise control of temperature and humidity: when the material has high requirements on the temperature and humidity of the air entering the drying room, the evaporating temperature and condensation temperature of the working fluid in the evaporator and condenser can be adjusted to meet the texture and appearance of the material. and other requirements.

4. Recovery of useful volatile components: some materials contain volatile components (such as fragrance), when using heat pump drying, in the drying room, volatile components and moisture are vaporized into the air together, and the air containing volatile components When the evaporator is cooled, the volatile components in it are also liquefied and discharged together with the condensed water, collect the condensed water containing the volatile components, and separate the useful volatile components by an appropriate method.

5. Environmental protection and pollution-free: the drying medium in the heat pump drying device is in a closed cycle, and there is no pollution caused by material dust, volatile substances and odors discharged to the environment with the drying exhaust gas; the waste heat in the exhaust gas of the drying chamber is directly recovered by the heat pump To heat the cold and dry air, there is no thermal pollution of the unit to the environment.

6. Low temperature drying: By controlling the working conditions of the device, the temperature of the hot dry air in the drying chamber is between 20 and 80 °C, which can meet the high-quality drying requirements of most heat-sensitive materials; the closed cycle of the drying medium can avoid Impurity contamination that may be brought to the material by the exchange with the external gas, which is especially important for food, medicine or biological products.

7. Drying of flammable materials: When the material is sensitive to oxygen in the air (easy to oxidize or burn and explode), an inert medium can be used instead of air as the drying medium to achieve anaerobic drying.

8. The heat pump dryer is suitable for a wide range of materials. The materials suitable for drying are mainly materials that can withstand temperatures between 20 and 80 °C during the drying process, or materials that can withstand higher temperatures but are more energy-efficient or safe to use heat pump drying. Materials that have been researched and applied more, such as wood, grains, seeds, edible fungi, medicinal materials, seafood, biologically active products, tea, paper, etc.

9. Compared with other low-temperature (air temperature in the drying chamber < 40℃) drying devices (such as microwave drying, vacuum drying, freeze drying), due to the small initial investment of equipment and low operating costs, the heat pump dryer device has obvious advantages. economical. The equipment cost of the heat pump drying device is mainly the heat pump part and the drying chamber part, of which the drying chamber part has the same requirements as the ordinary convection drying chamber, and there is no special air tightness and pressure bearing requirements.

10. Compared with ordinary drying devices (air temperature in the drying room > 40 °C), the initial investment of heat pump dryers is generally higher than that of electric air heating devices, gas or coal-fired hot blast stoves, and the initial investment of drying devices is generally higher. Compared with ordinary drying devices, heat pump dryer drying devices have high energy efficiency, low operating costs, and still have certain advantages in overall economy.

Drying and insulation room

The drying room insulation room is made of polyurethane rigid foaming process. Using the principle of rolling barrels, the metal plate is placed on a specially designed plate feeding belt, and the polyurethane foaming agent is sprayed on the metal plate by a spraying device. After high temperature treatment The foaming agent is foamed between the metal plates to complete the three-layer one-time integrated polyurethane (PU, PIR) metal sandwich panel.

Polyurethane is currently internationally recognized as the best thermal insulation material. It has low thermal conductivity, good load resistance, high flexural strength, no water absorption, no decay, no moth and rat bite, good flame retardancy and large temperature resistance range. The heat transfer due to the temperature difference between inside and outside can be reduced to achieve greater efficiency of the drying system.

Optional foam thickness：60、75、100、120、150、180、200mm。

Metal plate specifications are optional: embossed aluminum plate, stainless steel plate, color zinc steel plate, salted steel plate, galvanized plate.
