Mechanical separation device for shells and meat of crab legs

Abstract

The invention relates to a mechanical separation device for shells and meat of crab legs, belonging to the field of fishery machinery. The mechanical separation device comprises a worktable, a vibration feeding mechanism and a rolling shaft extrusion mechanism, wherein the vibration feeding mechanism and the rolling shaft extrusion mechanism are fixed at the front and rear ends of the worktable, respectively; the vibration feeding mechanism comprises a feeding hopper, a vibration generation device and a conveying slide rail; the rolling shaft extrusion mechanism comprises a support seat, an upper rolling shaft, a lower rolling shaft, a driving mechanism, a front scraping plate and a rear scraping plate; the upper rolling shaft and the lower rolling shaft are distributed up and down, the driving mechanism is used for driving the upper rolling shaft and the lower rolling shaft to rotate, and the front scraping plate and the rear scraping plate are arranged on the front and rear sides of the lower rolling shaft and downwards incline from front to back. To-be-processed crab legs are poured into the feeding hopper, enter the conveying sliding rail and downwards slide to the rolling shaft extrusion mechanism from a discharging hole of the conveying hopper by virtue of vibration of the vibration generation device, and are extruded by the upper rolling shaft and the lower rolling shaft, and then the shells and the meat of the crab legs are separated. The mechanical separation device is high in automation degree and applicable to crab legs of various sizes, the labor intensity of workers in the separation process of the shells and the meat of the crab legs is greatly reduced, and the production efficiency and the economic benefit are increased.

Description

Technical field [0001] The invention belongs to the field of fishery machinery, and particularly relates to a mechanical crab leg shell meat separation device. Background technique [0002] Crabs are deeply loved by consumers because of their rich protein and trace elements and their delicious taste. At present, my country's crab products are still mainly sold fresh, mainly for individuals with a weight of more than two to two, and the market demand for individuals below two to two is not strong, and the price is very low. At present, most of the low-value and small-size crabs are deep-processed, and the crab meat is processed into crab meal and other storage-resistant foods. As an intermediate material, this can not only increase the utilization value of low-value and small-size crabs, but also greatly improve crab breeding. Overall economic benefits. [0003] At present, most crabs are separated manually. The main method is to squeeze and scrape the cleaned and steamed crabs wi...

Problems solved by technology

Using this method not only has high labor intensity and low processing efficiency, but also causes product pollution and affects the quality and safety of food.

Patent 201210232757.4 proposes a mechanical shell-meat separation method for different body parts of river crabs, such as crab body and crab legs. It cannot be completed automatically. At the same time, different specifications of crab legs correspond to different sizes and thicknesses. Therefore, different equipment needs to be used to adapt to different crab leg sizes, which increases the processing cost.
