Prawn shelling qualified rate detection device based on multi-touch identification

Abstract

The invention relates to a prawn shelling qualification rate detection device based on multi-touch identification. The prawn shelling qualification rate detection device comprises a quantitative introduction device, a hardness detection system, a roughness detection system, a conveyor belt and a data processing system, the quantitative guide-in device, the hardness detection system and the roughness detection system are sequentially arranged in the conveying direction of the conveying belt; and the hardness detection system and the roughness detection system are connected with the data processing system, so that the shelling qualification rate of the mechanically shelled prawns is detected. According to the method, the prawn meat and shell characteristics are obtained in a multi-touch mode, the accuracy of prawn shelling qualification rate detection is guaranteed, and the method belongs to the field of aquatic product processing.

Description

technical field [0001] The invention relates to the field of aquatic product processing, in particular to a detection device for qualified rate of prawn shelling based on multi-touch recognition. Background technique [0002] Shrimp peeling is one of the most important links in the deep processing of prawns. Manual peeling is labor-intensive and low in production efficiency. At this stage, more prawn shelling equipment is used, which effectively improves the productivity of prawn products and reduces production costs. However, due to the imperfection of the existing shrimp peeling equipment technology and equipment, the peeling performance is not stable enough, it is necessary to manually sort the unpeeled unqualified shrimp, but the manual operation is easy to cause the shrimp body to be contaminated by bacteria, which affects the freshness of the product and quality. Therefore, it is of great significance to realize the automatic detection of the pass rate of shrimp pee...

AI Technical Summary

Problems solved by technology

Regarding the morphological characteristics, according to the different shelling requirements of prawns, there are tailed prawns, butterfly prawns, Western-style prawns with tails, and whole-shelled prawns, etc., which makes it difficult to fully characterize the species of prawns peeled off by morphological characteristics. The identification of prawn meat shells needs to be based on specific requirements. Different features are used, and the universality is poor; for the color feature, the color of shrimp meat and shrimp shell is similar, and it varies with different shrimp species, processing methods, freshness, etc., and it is difficult to obtain an accurate identification threshold for effective distinction. The recognition accuracy is low; for texture features, the shelling environment of prawns is relatively special, and it is difficult to obtain high-quality texture features of prawns due to the influence of the operating environment such as reflection of production and treatment water, uncertain vibration of conveying machinery, and dynamic changes in the position and posture of prawns.

[0004] To sum up, the visual perception method is easily disturbed by factors such as shrimp species and environment in the identification of prawn meat shells, and it is not universal
