The support is equipped with multiple layers of grid fenders connected to the transmission device, the transmission device is connected to hanger brackets, the support is provided with a soaking tank, a spray pipe, a seasoning tank and the drying box from left to right in order, the transmission device comprises a motor, belt pulleys and a conveyor belt, the top and the end of the support are equipped with belt pulleys, the grid fenders of the support are provided with uniformly distributed belt pulleys, the hanger brackets are connected to the conveyor belt, and are composed of cross rods and connecting rods, the connecting rods are provided with clips, and the surfaces of all components on the hanger brackets are provided with a rust-proof and heat resistant coating. The drying device provided by the invention improves the quality of large yellow croakers, greatly increases the product yield and reduces damage of large yellow croakers, can realize pipelined operation, and has very remarkable economic benefits and application prospects.

Description

technical field [0001] The invention belongs to the technical field of aquatic product processing, and in particular relates to a drying device for large yellow croaker. Background technique [0002] my country has a long coastline and rich fishery resources. In Zhejiang Province alone, there are more than 1 million tons of dried aquatic products every year, and the electricity consumption reaches 400-500 million kWh. Due to the high water content and high protein content of aquatic products, the muscle fibers will gradually shrink and be closely connected during the drying process. Therefore, the traditional hot air drying makes the outer layer of aquatic products crusted, which is not conducive to water evaporation, slow drying speed and huge energy waste (heat The gas is directly discharged into the atmosphere). In addition, if the drying temperature is too high, it will cause fat oxidation and Maillard browning, resulting in bad smell and great damage to heat-sensitive i...

Problems solved by technology

Therefore, the existing drying methods are not conducive to the development of the dried aquatic products industry, and are also an urgent problem to be solved at present.

[0003] Existing technologies such as Chinese Invention Authorized Patent Documents, Authorized Notice No. CN 102488240 B, this invention relates to a device for processing aquatic products, and aims to provide a device for processing fish products that realizes single hanging cleaning, seasoning and drying, including Cleaning-seasoning device, mobile drying rack and several groups of unit suspension devices; the unit suspension device is composed of a square outer frame and a plurality of cross bars installed in parallel inside the outer frame, and the clamps are installed on each cross bar Above, the outer frame of each single suspension device has the same external shape and external dimensions; the cleaning-seasoning device is a continuous production equipment integrating cleaning and seasoning, the single suspension device and the cleaning-seasoning device, mobile drying rack There is a good matching relationship between them. This invention overcomes the problems of serious damage, low yield and low degree of mechanization in the processing of instant small miscellaneous fish, and realizes the assembly line processing of cleaning, seasoning and drying; ensures the integrity of the product, It improves the quality of the product and has extremely significant economic benefits and application prospects. However, the device is prone to rust and deformation after long-term use of the single suspension device, and there is still room for improvement in drying and sterilization.
