The heat pump room dryer is a kind of enclosed dryer. The hot air is sent into the heat pump room through a fan to dry the indoor materials. Put another layer of the baffle on the material and the return air moisture exhaust port to facilitate the removal of moisture from the room and prevent the moisture from returning to the room again.
For materials such as fruits, vegetables, meat, etc., use 304 stainless steel trays to mount the materials, or use 304 stainless steel cart brackets to hang the materials on the cart.
Use 304 stainless steel trays or 304 stainless steel carts for fruits, vegetables, meat, and other materials placed in the dryer in the heat pump room
Heat pump food dryer temperature control system
Food dryers have high requirements for temperature control. High or low-temperature control will be detrimental to the drying effect of food. The high temperature easily damages the food and destroys the internal nutrition and taste of the food. Low temperature will result in incomplete drying of food, which may result in excessive moisture content or residues of certain meat microorganisms.
The heat pump room dryer is set with a temperature range of 20~80°C inside the dryer, which can satisfy most of the food drying work, and is a gentle drying method close to natural drying.
The heat pump food dryer machine can make the evaporation speed of the surface water of the material close to the migration speed of the internal water to the surface, so that the quality of the dried material is good, the color is good, and the product quality is high.
When the food dryer is drying materials, it is very important to maintain the indoor temperature. Poor thermal insulation results in the loss of heat, which will cause the dried materials to fail to achieve the expected results, and also extend the time for drying the materials. This is a very unfriendly behavior to the environment and resources.
Guoxin food dryer adopts 100mm polyurethane insulation board, which has an excellent insulation effect, and the temperature in the dryer room can hardly be lost.
Polyurethane insulation board has super strong self-adhesive performance, strong adhesion to roof and external wall, good wind resistance and negative wind pressure resistance, and has many functions such as heat preservation, waterproofing, sound insulation, vibration absorption, and moisture resistance. It is often used for the insulation of refrigerators, cold storage, and incubators.
The working principle of the heat pump room dryer
The working principle of the heat pump dryer is that the refrigerant is compressed by the compressor to become high-temperature and high-pressure gas, which enters the condenser to release heat, and the heat from the condensation is sent to the barn by the circulating fan to heat the barn air (the highest air outlet The temperature can reach 75°C). As the temperature in the air increases, the moisture in the material will gradually evaporate, and then the fresh air dehumidification system will dehumidify, so as to achieve the effect of drying.
The inside of the dryer is a circulating system, and there is a layer of baffle between the air inlet and the air outlet to help the airflow to circulate and dehumidify, which can efficiently complete the drying of the material.
The heat pump food dryer is a powerful dryer that can be used to dry fruits, vegetables, meat, refractory materials, nuts, and other materials.
