The heat pump food drying equipment
is specially designed for industrialized food processing and mass production. It has a wide range of applications, green and environmentally friendly, low energy consumption, and is simple to operate and convenient. GELGOOG can offer customized food processing solutions.
Introduction of heat pump drying equipment
※ The heat pump dryer euipment uses the principle of reverse Carnot cycle to absorb heat from the air and transfer it to the room, thereby increasing the temperature in the drying room, and cooperating with fans and other equipment to achieve drying of materials.
※ The heat pump is mainly composed of condenser-compressor-throttle valve-condenser-compressor and other devices to form a circulating system. The refrigerant circulates in the system under the action of the compressor.
※ The liquid refrigerant absorbs heat from the environment in the evaporator and quickly evaporates into a gaseous state; the gaseous refrigerant is compressed in the compressor and enters the condenser, and the refrigerant enters the condenser The high-temperature heat is released to heat the air in the drying room, and at the same time it is cooled and converted into liquid; the liquid refrigerant enters the evaporator again to absorb heat and convert it into gas.
※ The air around the condenser continuously transfers heat to the refrigerant. The circulation of the refrigerant realizes the continuous transfer of the heat in the air to the drying room.
Working Principle of heat pump drying equipment
The heat pump condenser transfers heat to the air in the heat pump drying room, and the hot air heats the dried materials under the action of the circulating fan, and at the same time takes away the moisture of the materials.
1. The heating process of the heat pump drying room system: during the drying process of the material, the heat pump host cyclically heats the drying room. When the temperature in the drying room reaches the setting (for example, the temperature is set to 60°C), the heat pump host stops heating, and when the temperature in the drying room is lower than the set value, the heat pump host starts to supply heat.
2. The process of dehumidification
: Dehumidification system, with automatic system control. For example: set temperature: 55℃; humidity: 60%; when the temperature and humidity in the drying room reach the set value, the exhaust fan will automatically start to discharge the humid air in the drying room into the environment; When the temperature and humidity of the dry room are lower than the set value, the dehumidification system will automatically shut down.
The drying dehydrator equipment can be used to process mango, lemon, banana, ginger, garlic, fig, chili, onion, moringa leaves, tomato, pineapple, coconut flakes, mint herbs, seaweed etc.
The heat pump drying equipment adopts a PLC automatic control system to control the temperature and humidity in the drying room, and can set the temperature, humidity and drying time of the drying, so as to adapt to different drying materials. There is a temperature and humidity sensor in the drying room to monitor the temperature and humidity changes in the drying room in real time. The finished dehydratored products after drying should be sorted, packaged and stored in time to avoid moisture regain affecting the quality and storage time of the final products.
