The invention discloses a belt-type infrared radiation drying system which comprises an infrared radiation drying unit, a control system and a main body, wherein the infrared radiation drying unit adopts a multilayer structure, and comprises infrared radiation light wave boards, a conveying belt, an L-shaped supporting rack, a fixing device, a supporting rack, a heating module clamping groove, a driving roller, a driven roller, a power chain and a motor; the infrared radiation light wave boards are mounted in the infrared radiation drying unit, and are correspondingly arranged above and below the conveying belt, and is used for uniformly radiating energy to a material on the conveying belt in an infrared radiation manner during work; the control system is used for matching of infrared wave wavelength and peak of the infrared energy according to the infrared spectrography of the material to be dried. The infrared radiation drying system has the advantages that the production cost is very low; the service life is long; the electro-thermal conversion efficiency reaches up to 99 percent; compared with those of the traditional infra-red drying equipment, the drying time of the infrared radiation drying system is shortened by 30 percent or higher, and the energy conservation effect is improved by 35 percent or higher.

Description

technical field [0001] The invention relates to a far-infrared drying system, in particular to a belt-type infrared radiation drying system and a drying method thereof. Background technique [0002] Infrared radiation drying technology is a drying method that relies on electromagnetic radiation to transmit energy, and its electromagnetic wavelength range is usually between 0.76 and 1000 μm. Infrared radiation can penetrate the surface of the material and heat the material from the inside, and the energy of infrared radiation is directly coupled with moisture, thus effectively improving the drying efficiency of the material. Infrared drying and infrared combined hot air drying technology are technologies developed in recent years, which have the advantages of strong heating capacity and fast heating speed. It can combine the enzyme inactivation and dehydration processes into one, and has been applied in the drying of crops, special agricultural products, fruits and vegetable...
