The working principle of agricultural and sideline product dryers is to use the reverse Carnot principle. The refrigerant (mostly a mixed refrigerant) is compressed by the compressor to become a high-temperature and high-pressure gas, with a gas temperature of 100-110 ℃. This high-temperature gas enters the heat exchanger (condenser) through a pipeline (copper pipe), and then through a fan, the heat generated by the heat exchanger (condenser) is sent to the drying room to heat and dry the materials, The moisture of the heated materials inside the drying room evaporates and is discharged outside the drying room through a dehumidifier or dehumidifier, thereby achieving the purpose of drying. Characteristics of agricultural and sideline product dryers: 1. Easy to install: It is easy to install, occupies a small area, and can be installed indoors or outdoors. 2. Energy saving: With only a small amount of electricity, it can absorb a large amount of heat in the air, saving 75% of energy compared to electric heating dryers; Energy saving 66% compared to fuel and gas drying equipment; Compared to coal-fired dryers, it saves 30% energy and uses 1 kWh of electricity as 4 kWh. 3. Environmental protection: The combustion and emissions of *********** comply with food hygiene standards and are a sustainable and environmentally friendly product. 4. Safe and reliable operation: The entire system operates without the potential hazards of flammability, explosion, poisoning, short circuit, etc. that may exist in traditional dryers (fuel, gas, or electric heating), making it a safe and reliable fully enclosed drying system. 5. Long service life, low maintenance cost: It is developed on the basis of traditional air conditioning technology, with mature process technology, stable and reliable performance, long service life, and safe and reliable operation. 6. High degree of intelligence: Adopting PLC computer intelligent control, the drying process can be set according to the characteristics of the material, without the need for manual supervision, and can operate continuously for 24 hours. 7. Wide applicability: suitable for all products or materials in various industries that require drying, dehumidification, and dehydration.
