Embodiment Construction

[0025] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0026] For small fish with a body length of about 10cm, especially the "small miscellaneous fish" caught in the ocean, there are not only many varieties but also large differences in body characteristics. The manual method of removing the head and viscera is time-consuming and inefficient. It is very difficult to remove the head and viscera, so according to the characteristics of small fish, we have invented a mechanical processing method for removing the head and viscera of small fish, which may include the following steps:

[0027] (1) The step of placing the small fish on the fish conveyor belt through the fish directional feeder unit, which orients the heads of the small fish in the same direction and makes each small fish parallel Falling into the fish body adjustable distance positioning groove set on the fish body conveyor belt;

Abstract

The invention relates to a machining method and machining equipment for removing heads and viscera of small fishes and belongs to the field of fish processing. The machining method includes the followings steps of firstly, placing small fishes on a fish body conveying belt via a directional fish body feeder unit; secondly, placing the small fishes in distance-adjustable positioning grooves of the fish body conveying belt in a manner that the backs of the fish bodies face upwards and the bellies of the fish bodies face downwards, cutting off spines and peripherally connected muscular tissues via a disc cutter of a head cutting device while guaranteeing that the heads and the bodies of the backs of the fish bodies are cut off without cutting off flesh tissue of the bellies of the fish bodies and throat tissues connected with the viscera and the heads; thirdly, conveying the fish bodies not completely cut off and separated to a viscera remover device via a synchronous feeder, clamping and conveying the fish bodies, pulling and removing the heads, the viscera and connected throat tissues; and fourthly, conveying the fish bodies to a fish container, and feeding the heads and the viscera into other containers.

Description

technical field [0001] The invention relates to a fish processing method, in particular to a mechanical processing method and processing equipment for removing heads and viscera of small fish. Background technique [0002] Small fish, commonly known as "small miscellaneous fish", usually refer to small and low-value marine fishes, which are characterized by: many varieties, large differences in body characteristics, large output, and low market prices. In order to make good use of such low-value marine fishery resources, the small miscellaneous fish are usually treated first by removing the head and viscera, and then the rinsed fish body is used to process frozen surimi, various surimi products, and fish oil health products. and seasoned snack foods and other deep-processed products, while discarded fish heads, viscera and bone spurs and other leftovers are used to process fish meal. [0003] Although the operation method of artificially removing the head and viscera of sma...
