研究背景我国绝大多数农产品加工属于高投入、高消耗、高排放、低效率的增长方式,已经形成“资源难以为继,环境难以承受”的现状,安全环保、节能减排指标越来越具体和硬化,传统农产品干燥的粗放型、高消耗、高污染发展模式受到严重挑战。针对目前农产品传统干燥存在干燥周期长、效率低、耗能大、污染重、成本高、品质低等问题,采用太阳能干燥技术对农产品进行干燥是理想的方式之一,太阳能干燥温度在60℃以下,不会破坏农产品的营养价值,能满足大多数农产品在
Research Background Most agricultural products processing in our country belong to the mode of growth with high investment, high consumption, high emission and low efficiency, and have formed the status quo that “resources are unsustainable and the environment is unbearable”, safety and environmental protection and energy saving and emission reduction targets are increasingly coming The more concrete and hardened, the extensive, high-consumption and high-pollution development model of traditional agricultural products is seriously challenged. Aiming at the problems such as long drying cycle, low efficiency, heavy energy consumption, heavy pollution, high cost and low quality, traditional drying of agricultural products is one of the ideal ways to dry agricultural products by using solar drying technology. The solar drying temperature is below 60 ℃ , Will not undermine the nutritional value of agricultural products, to meet the majority of agricultural products in the
