Technical Field

Traditional open solar drying (i.e. natural sun drying) is the most common method of processing agricultural products, in which the material is laid in the sun to remove moisture. The method is simple to operate and low in drying cost, but the drying process is easily influenced by climate change and external environment, so that the dried product is easily subjected to secondary pollution of microorganisms, dust, rainwater and the like.
In addition to traditional open solar drying, drying techniques such as heat pump drying, freeze drying, infrared drying, etc. have also been widely used in the processing of food on an industrial scale. These technologies require large investments and are also associated with large fossil fuel consumption and greenhouse gas emissions. Drying is an industrial operation unit with energy-intensive and high-temperature chamber gas emission, and the consumed energy accounts for about 7-15% of the total industrial energy consumption in one country. The renewable energy source is used for drying the agricultural products, and the method can play an important role in food safety, low-carbon footprint, sustainable development and climate change inhibition. Thus, solar energy is a dry renewable energy source suitable for agricultural products.
