A fish skin extraction device

Abstract

This utility model discloses a fish skin extraction device, relating to the field of fish skin extraction technology. The utility model includes an extraction cylinder, a heating component, a scraping component, and a stirring component. The scraping component is disposed inside the extraction cylinder, and the stirring component is disposed inside the scraping component. The scraping component includes a first sleeve block, a second sleeve block, a third sleeve block, four side scraping plates, and four lower scraping plates. By configuring the scraping component, after the fish skin is boiled into a gel and discharged into the extraction cylinder through the gel discharge hole, the four side scraping plates and the four lower scraping plates can respectively scrape the inner wall and the arc-shaped inner wall of the extraction cylinder. Because the four side scraping plates and the lower scraping plates are all in contact with the inner wall of the extraction cylinder and the scraping movement is circular, it can effectively prevent residual material from accumulating in areas that the side scraping plates and the lower scraping plates cannot reach during the scraping process, resulting in a better scraping effect on the inner wall of the extraction cylinder.

Description

Technical Field

[0001] This utility model belongs to the field of fish skin extraction technology, and in particular relates to a fish skin extraction device. Background Technology

[0002] Fish skin extraction equipment extracts gelatin from fish skin through a series of processing steps. This gelatin is commonly known as fish glue.

[0003] A Chinese patent application (or patent) with publication number CN220110841U discloses a fish skin gelatin extraction device, comprising: a box body, on which two fixed plates are fixedly installed on the outer surface of the box body; and a guide rod, fixedly installed on one side of the opposite face of the two fixed plates; and a threaded rod, movably installed on the other side of the opposite face of the two fixed plates. The desired material, fish skin, is poured into the box body. The heating plate is turned on and the temperature is adjusted to 60℃~70℃ to heat the box body for gelatin extraction. First, the drive motor is started to rotate the stirring rod. Simultaneously, the rotation of the stirring rod rotates multiple stirring blades fixedly installed on the outer surface, thereby better extracting the fish skin material inside the box body. Stirring is performed to prevent the fish skin from sticking together. A protective box is fixedly installed on the outer surface of the drive motor to prevent damage to the drive motor. After stirring stops, the servo motor is started to rotate. The servo motor rotates at the same time, driving the threaded rod to rotate. The threaded rod drives the sliding plate, which is movably sleeved on the outer surface, to move back and forth. The movement of the sliding plate drives the U-shaped side scraper fixed at the bottom to scrape the inner wall and bottom of the box. This can better prevent the fish skin stuck to the inner wall and bottom from sticking to the bottom during cooking and causing it to burn. Moreover, the stirring rod moves along with the sliding plate driven by the threaded rod. This can achieve stirring in different parts of the box and better improve the extraction of fish skin gelatin.

[0004] The existing box is a rectangular box, but when using a U-shaped side scraper for scraping, the inner side of the U-shaped side scraper will continuously accumulate material during the reciprocating scraping. Since the U-shaped side scraper can only move back and forth, the accumulated material can only be manually processed later, which makes the scraping effect on the fish skin material inside the box relatively limited.

[0005] To address these issues, we provide a fish skin extraction device. Utility Model Content

[0010] The present invention is further configured such that the inner walls of the first sleeve block, the second sleeve block, and the third sleeve block are all slidably connected to the side wall of the drive shaft rod.

[0013] The present invention is further configured such that the side walls of the four side scraping plates are slidably connected to the inner wall of the extraction cylinder.

[0017] 1. This utility model, by setting up a scraping component, allows four side scraping plates and four lower scraping plates to scrape the inner wall and the inner wall of the arc-shaped surface of the extraction cylinder after the fish skin is boiled into glue and discharged into the extraction cylinder through the glue discharge hole. Since the four side scraping plates and the lower scraping plates are all in contact with the inner wall of the extraction cylinder and the scraping movement is a circular motion, it can effectively prevent the accumulation of residual material in places that the side scraping plates and the lower scraping plates cannot reach during the scraping process, and the scraping effect on the inner wall of the extraction cylinder is better.
