In order to implement the national “Twelfth Five-Year Plan†energy saving and emission reduction policy guidelines and promote the wide application of new energy sources such as solar energy in the agricultural product processing industry, the Ministry of Agriculture Products Processing Bureau of the Ministry of Agriculture is particularly concerned about energy saving, emission reduction and drying equipment for agricultural product processing. Solar drying equipment The most recently admired is the direct thermal solar fruit and vegetable drying equipment, which has a heat collection area of ​​192 square meters. Each batch can handle 3-5 tons of fresh materials with a maximum temperature of 75 degrees Celsius. The drying time of the equipment for beans, tomatoes, eggplants, peppers and other agricultural products is about 5-7 hours, and the power consumption is only 30-42 degrees; it can make the dry raisin green grade product rate more than 60% higher than the natural air-curing house. And the quality of the finished product is good. The currently promoted solar drying facilities are mainly divided into direct-heat solar energy fruit and vegetable drying equipment, hybrid solar energy multifunctional fruit and vegetable drying equipment, and production-type high-efficiency solar heat collecting van fruit and vegetable drying rooms. In order to promote the application of solar drying technology in the agricultural product processing industry, the Department of Agricultural Products Processing of the Ministry of Agriculture has conducted in-depth research on solar energy fruits and vegetables drying technology, processes, and equipment, and has made important progress. The new solar energy fruit and vegetable drying technology promoted by this demonstration is a solar energy drying comprehensive utilization technology that integrates functions of dust removal, cleaning, sterilization, drying, solar heat collection, drying, and self-control of fruit and vegetables. It has a short drying cycle and high efficiency. Good product quality and other advantages will play an important role in the development of the rural economy, saving conventional energy sources, avoiding environmental pollution, improving product quality, changing outdated production and processing methods, and getting rich farmers. News link: Solar drying is to make the material to be dried, either directly absorb solar energy and convert it into heat energy, or obtain heat energy through convective heat exchange through the air heated by the solar heat collector, and then go through the surface of the material and the internal of the material described above. During the heat transfer and mass transfer process, the moisture in the material is gradually vaporized and diffused into the air to finally achieve the purpose of drying.
