Description

technical field [0001] The invention relates to the technical field of aquatic product drying, in particular to a multi-energy cooperative self-adaptive drying system and a drying method. Background technique [0002] Generally, the water content of aquatic products is more than 70%, and they are easy to rot and deteriorate at room temperature. Therefore, timely and effective processing and reasonable storage and transportation methods must be adopted to maintain the quality of aquatic products. [0003] At present, the storage and processing methods of aquatic products are mainly drying processing and freezing processing. Among them, the technical advantage of freezing processing is to better preserve the original quality of aquatic products, but the upfront cost of freezing equipment is high, and the storage and transportation process is complicated and expensive; In contrast, dried and processed aquatic products are light in weight and small in size, which can not only re...

Problems solved by technology

However, single solar drying has obvious shortcomings. It is greatly affected by conditions such as day and night, sunny and rainy, and seasons. The stability of the working process is poor. The temperature and humidity in the solar radiation drying room fluctuate greatly, making it difficult to achieve the predetermined drying process.

Heat pump drying technology is a new type of environmental protection, high efficiency and energy saving technology. It has the advantages of high energy utilization rate, environmental friendliness, and wide adjustable range. However, due to the high moisture content of aquatic products, using heat pump drying technology alone still has problems such as high energy consumption and high initial investment.
