Intelligent adhesive spraying equipment for crayfish ice coating and freshness locking

Abstract

The invention relates to the field of freezing and fresh keeping of aquatic products, in particular to intelligent spraying equipment of an adhesive for crayfish ice coating and fresh keeping. Wherein the control panel is arranged on the side wall of the shell and is used for setting different spraying modes of an adhesive; the CCD industrial camera is mounted on a sliding block mounting seat of the moving device and is used for collecting the spraying condition of the adhesive on the surface of the crayfish in the shell; the moving device is fixedly installed on the top of the inner side of the shell, and translation of the CCD industrial camera is facilitated. The adhesive groove pipe is fixedly installed on the upper portion of the shell, and the pressure pump is used for spraying and boosting adhesive and communicated with the adhesive groove pipe through the connecting bent pipe. The adhesive spraying device is fixedly arranged in the shell and is connected and communicated with the adhesive groove pipe; according to the device, manual spraying is replaced with industrial control intelligent spraying, it is guaranteed that the crayfish adhesive is sprayed evenly, it is further guaranteed that ice coating of crayfishes is even, and the freshness locking effect of crayfish individuals is good.

Description

technical field [0001] The invention relates to the field of freezing and fresh-keeping of aquatic products, in particular to an intelligent spraying device for an adhesive used for ice-locking freshness of crayfish wrapped in ice. Background technique [0002] At present, the main preservation methods include low temperature preservation, chemical preservation, modified atmosphere preservation and ionizing radiation preservation, among which the low temperature preservation method is the most widely used in the preservation of aquatic products. Frozen preservation uses low temperature to reduce the central temperature of aquatic products to below -15 °C, and then store them in the range of -40 to -18 °C, which greatly extends the shelf life of aquatic products. [0003] The existing preservation method of crayfish adopts the frozen preservation method with the longest preservation period. During the freezing process, the ice crystals formed by the water destroy the internal...

AI Technical Summary

Problems solved by technology

[0003] The existing crayfish preservation method adopts the frozen preservation method with the longest preservation period. During the freezing process, the ice crystals formed by the water destroy the internal structure of the crayfish, resulting in the deformation of the crayfish and the loss of nutrients, and the quality is not as good as fresh Crayfish, the meat is loose and shrinking, and the taste is poor

The crayfish preserved by ice-packing technology will not deform the crayfish, and at the same time, it can well lock the nutrients of the crayfish. The meat is firm and tastes good, which can solve the above problems. In the fresh-keeping process, the crayfish need to be refrigerated by ice coating for many times. In order to ensure the uniform and reliable ice coating of the crayfish, it is necessary to spray the adhesive on the crayfish many times so that the ice layer on the surface of the crayfish will not fall off easily. The adhesive is sprayed manually by the workers. The amount of spraying is determined by the experience of the workers. The process is difficult to monitor, and it is easy to cause large differences in the ice coating of individual crayfish, and the thickness of the ice coating is uneven, which in turn leads to large differences in the freshness of the crayfish. Affects the quality of each batch
