Staggered inner claw tooth type shrimp head removing method and system

Abstract

The invention discloses a staggered inner claw tooth type shrimp head removing method and system. The method comprises the steps that S1, shrimps enter a conveying roller to be conveyed only through a feeding opening; s2, image information of the shrimps is obtained, shrimp information of the batch of shrimps is identified according to the image information of the shrimps, and the shrimp information comprises shrimp types, shrimp body lengths, shrimp body diameters and weak connection positions of shrimp bodies and shrimp heads; s3, according to the obtained shrimp information, the distance between the inner shifting teeth in the conveying roller and the adjacent outer rake teeth is adjusted; s4, the outer rake teeth and the inner shifting teeth form cross shearing motion; s5, in the process that the shrimps are conveyed in the conveying roller, the weak positions where the shrimp heads and the shrimp bodies are connected are continuously cut, and the shrimp heads and the shrimp bodies are separated. According to the invention, high-efficiency low-loss separation of shrimp heads and shrimp bodies can be automatically realized, manual material arrangement is not needed, continuous automatic processing is realized, the most appropriate distance between the inner shifting teeth and the outer rake teeth can be adjusted, and the head removal rate of 98% or above is realized.

Description

technical field [0001] The invention relates to the technical field of shrimp processing, in particular to a method and system for deheading shrimp with staggered inner claws. Background technique [0002] When shrimps are processed into foods such as peeled shrimps, breaded shrimps, and spicy shrimps, it is generally necessary for shrimps to be headed, gutted, and shelled. At present, most shrimp processing enterprises use manual processing in the shrimp deheading process, and a small number of large-scale enterprises use mechanized shrimp decapitation equipment, mainly including knife-cut decapitation equipment, tooth decapitation equipment and roller decapitation equipment. There are three kinds of head equipment. [0003] But the inventor finds that there are following problems in the prior art in the process of realizing the present invention: [0004] 1. Manual removal of shrimp heads requires a lot of labor, and increases the risk of cross-contamination between huma...

AI Technical Summary

Problems solved by technology

[0004] 1. Manual removal of shrimp heads requires a lot of labor, and increases the risk of cross-contamination between humans and shrimps during operation

[0005] 2. Knife-cut head removal equipment and tooth-stripping type head removal equipment require manual feeding and manual placement of the shrimp to a suitable position. Since the back of the shrimp is mostly curved, it is easy to cut off the head when using the knife-cut method. More shrimp meat, resulting in greater waste

The roller-type deheading equipment does not need to manually swing the shrimp. The shrimp head is separated from the shrimp body by rubbing. However, this method will cause the shrimp body to separate from the shrimp tail, which is not suitable for subsequent processing into butterfly shrimp, anchovy shrimp and other products.
