Separating device for sea fish and sea shrimps

Abstract

The invention provides a separating device for sea fish and sea shrimps and belongs to the technical field of aquatic product processing. The separating device solves the problem of separating sea fish and sea shrimps in the prior art. The separating device for sea fish and sea shrimps comprises a groove for fish, shrimps and seawater to pass through and fish and shrimp collecting devices. The separating device is characterized in that the groove comprises a bottom plate, a left lateral plate and a right lateral plate; electrodes are arranged on the left lateral plate and the right lateral plate; a magnet is arranged under the bottom plate; and the left fish and shrimp collecting device and the right fish and shrimp collecting device are arranged at the outlet position of the groove. The separating device separates the fish and the shrimps through electric stimulus response difference of the shrimps and fish, is not limited by relative sizes of the fish and the shrimps and is suitable for live fish and live shrimps.

Description

technical field [0001] The invention belongs to the technical field of aquatic product treatment, and relates to a fish and shrimp separation device, in particular to a sea fish and shrimp separation device. Background technique [0002] When fishing in the ocean with fishing nets, the fish and shrimp coming from the net are mixed together and difficult to separate, which brings inconvenience to the subsequent handling, processing and storage. Manual sorting is usually required, but the efficiency is low and the labor intensity is high. [0003] Due to the existence of this problem, after searching, it is found that the existing artificial fish and shrimp separation methods have gravimetric method, size method, etc., and these methods are to utilize the difference of fish and shrimp size or weight to separate fish and shrimp. This method is only applicable to the situation that the size or weight of fish and shrimp differ greatly, and the effect of sorting is better. For the...

AI Technical Summary

Problems solved by technology

This method is only suitable for the situation where the size or weight of fish and shrimp is quite different, and the sorting effect is better. For the situation of similar weight or size of fish and shrimp, it is not easy to separate

These methods usually require the fish and shrimp to be separated from the water, which will increase the damage to the fish and shrimp, and easily cause injury or death of the fish and shrimp

In addition, these methods are not suitable for the separation of live fish and shrimp, because live fish and shrimp will jump and are not suitable for machine separation
