Energy-saving drying device for aquatic products

Abstract

The invention provides an energy-saving drying device for aquatic products. The energy-saving drying device comprises an air pump, a compressor connected with the air pump, a drying box connected with the compressor and a heat pump system. The left side of the air pump is sequentially connected with a first control valve, the compressor and a condenser through a pipeline. The condenser is connected with the drying box. The right side of the drying box is sequentially connected with an evaporator, a fifth control valve and a plate heat exchanger through a pipeline. The plate heat exchanger is connected with the air pump. The air pump is further connected with a solar module. The solar module is composed of a solar panel and a storage battery. The heat pump system comprises the compressor, the condenser and the evaporator. A pipeline on one side of the evaporator is provided with a fourth control valve and a fan. According to the drying device, operation is convenient, aquatic products in multiple suspension cages are dried at a time, space is saved, the resource utilization rate and drying efficiency are improved, green energy resources are used, and the dried aquatic products are high in quality.

Description

technical field [0001] The invention belongs to the technical field of aquatic product processing, and in particular relates to an energy-saving drying device for aquatic products. Background technique [0002] Drying is a very important processing method and preservation technology. Hot air drying is currently the most widely used and most economical drying method. However, due to the large temperature gradient formed inside and on the surface of the dried material, it is easy to cause quality degradation and solute loss. Great influence on food quality. [0003] Existing technologies such as Chinese Invention Authorized Patent Literature, Authorized Notice No. CN 103610214 B, the invention discloses an energy-saving device for normal-temperature circulation drying of aquatic products, which belongs to the field of aquatic product processing equipment, including an air pump, a first control valve, a second Control valve, condenser, third control valve, drying chamber, four...

[0003] Existing technologies such as Chinese Invention Authorized Patent Literature, Authorized Notice No. CN 103610214 B, the invention discloses an energy-saving device for normal-temperature circulation drying of aquatic products, which belongs to the field of aquatic product processing equipment, including an air pump, a first control valve, a second Control valve, condenser, third control valve, drying chamber, fourth control valve, evaporator, fifth control valve, plate heat exchanger, fan, sixth control valve, compressor and heat pump system, the air pump left The side is connected with the first control valve, compressor and condenser in turn through the pipeline, and then enters the drying room. A third control valve pipeline is also connected in parallel between the left drying room and the air pump. The two ends of the machine are connected in parallel with the pipeline of the second control valve; the right side of the drying room is connected with the evaporator, the fifth control valve, and the plate heat exchanger in turn through the pipeline, and then enters the air pump, and the air pump is between the right drying room and the air pump. The pipeline with the sixth control valve is connected in parallel; the pipeline built in the plate heat exchanger is connected in parallel on the pipeline between the drying chamber and the evaporator, but there is no sterilization facility in the drying chamber of the device, which is in terms of sterilization and energy saving and emission reduction There is still room for improvement
