The "green pearl" Xinjiang green raisin, which is renowned both at home and abroad, will bid farewell to "grey heads and dirt" together with many other fruits and vegetables to advance into high-quality products. This is due to the scientific research project undertaken by the Planning and Design Institute of the Ministry of Agriculture that “the hybrid solar-powered multifunctional fruit and vegetable drying equipment” and the “productive high-efficiency solar-heating chamber-type fruit and vegetable drying room” passed the expert appraisal on January 20. Experts believe that this achievement is in line with the requirements of China's energy-saving and emission-reduction strategies and meets the urgent needs of the development of the agricultural product processing industry; it is technically a domestic initiative and has reached the international advanced level; it is recommended to promote it.
Professor Zhu Ming, dean of the Ministry of Agriculture Planning and Design Institute, who is in charge of researching the project, told reporters that some of China's fruit and vegetable-producing areas are far away from the market, and the transportation costs of fruits and vegetables are high and losses are high. %-30%, equivalent to RMB 75 billion; and the related agricultural product processing industry has high input, high energy consumption, high material consumption, high pollution, poor quality of processed products and low selling price, which is not conducive to environmental protection and increasing farmers' income.
Experts said that these two projects will apply solar energy collector and automatic control technology for the first time in the drying of specialty fruits and vegetables in Xinjiang. "Hybrid solar multifunction fruit and vegetable drying equipment" combines hybrid solar energy collection technology, van-kiln kiln double ventilation technology, automatic control auxiliary heating and air filtration-ultrasonic cleaning-ozone sterilization technology The integration has greatly improved the quality of raisins, shortened the drying cycle by more than two-thirds, solved the problems of long production cycle and poor sanitation quality caused by traditional air drying and open-air drying, and researchers have also used the equipment for jujube, Apricot and wolfberry have been subjected to a drying test, the energy-saving effect has been remarkable, and the drying quality has also been significantly improved. "Production-type high-efficiency solar-heating box-type fruit and vegetable drying room" can also greatly improve the quality of Xinjiang green raisins, drying cycle is reduced by more than half.
