the heat pump drying technology uses a working medium (such as ammonia, water, etc.) to evaporate under reduced pressure in the evaporator, so that the surface temperature of the evaporator is lower than the indoor air dew point, so that when the air flows through the evaporator, it is cooled and lowered below the dew point. When the excess steam in the air is condensed and precipitated on the surface of the evaporator, the condensed water is poured into the water tray and then drained into the water container by the drain pipe. after the liquid working medium is heated and vaporized, it is sent to the condenser through the compressor, and the condenser emits a large amount of latent heat of vaporization under high temperature and high pressure. When the air cooled in the evaporator passes through the condenser, the endothermic temperature rises, and is discharged in a dry state, and is mixed with the room air. Thereby reducing the indoor air humidity and achieving the purpose of drying and dehydrating.

4.Hot air circulation oven application range:
Hot air circulation oven is suitable for heat curing, drying and dehydration of materials and products in pharmaceutical, chemical, food, agricultural and sideline products, aquatic products, light industry, heavy industry and other industries. Such as raw materials, traditional Chinese medicine, Chinese medicine decoction pieces, extracts, powders, granules, granules, water pills, packaging bottles, pigment dyes, dehydrated vegetables, dried fruits, sausages, plastic resins, electrical components, baking varnish and so on.
Remarks: the company's deep oven and fresh vegetables special oven can be set to different drying temperatures and time control.
the company produces chemical fiber and paper special ovens, which can control different dry relative humidity and control time and temperature.

6.Composition of heat pump drying system

1. Main machine (heating system): absorbs free heat from the air with little electric energy input, and USES it to dry materials.

2, drying room: used for placing materials, and insulation to avoid heat loss.

3. Circulating air system: bring heat to every corner of the drying room to raise the temperature of the drying room, and take away moisture from the materials.

4. Moisture drainage system (drying system): the purpose of drying is to discharge the moisture with high humidity in the drying room.

5. Waste heat recovery system: the drying system has a total of 3 waste heat recovery lines, which can minimize the loss of heat and achieve high efficiency.

6. Drainage system: condensate water is discharged to the outdoor to avoid increasing the humidity of indoor air.

7, programmable intelligent control system: according to the most appropriate drying process curve, automatic adjustment of temperature and humidity, drying time, intelligent operation.
