Duplex skin-removing device and method for poultry paws

Abstract

The invention relates to a duplex skin-removing device and method for poultry paws. The duplex skin-removing device for poultry paws comprises a rack, two vertical paw-removing apparatuses, a feed distribution mechanism, a power mechanism and a programmable PLC (programmable logic controller) control device, wherein the two vertical paw-removing apparatuses are arranged on the rack side by side, the feed distribution mechanism is arranged on the two vertical paw-removing apparatuses, the power mechanism is arranged below the rack, and the programmable PLC control device is used for controlling the vertical paw-removing apparatuses and the feed distribution mechanism. In the invention, two vertical paw-skin removing cylinders are connected together side by side, the feed distribution mechanism is added on the two vertical paw-skin removing cylinders, a manual discharge door of an original vertical paw-skin removing machine is changed into a pneumatically-controlled automatic door, and an alternating operating order of feeding, paw machining and discharging of the two vertical paw-skin removing cylinders is controlled by the programmable PLC control device. In such a way, the device disclosed by the invention inherits the advantage (the paw-broken rate is low) of a vertical paw-skin removing machine and the advantage (the machine can carry out continuous production) of a horizontal paw-skin removing machine, and solves the problem of high paw-broken rate existing in the horizontal paw-skin removing machine and the problem that the vertical paw-skin removing machine is required to be operated by labor power. The reduction of the paw-broken rate means that a large amount of economic losses (caused by a chicken-paw broken rate) of a factory using the device disclosed by the invention can be reduced, and the production efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of poultry slaughtering and processing, and specifically relates to a device and method for automatically removing yellow skin of chicken feet by adopting double-connected vertical chicken feet peeling cylinders to work alternately to realize continuous feeding operation. Background technique [0002] Peeling chicken feet is a by-product processing in the poultry processing industry. But for the Chinese market, although chicken feet are a by-product, the market price is not low. Therefore, Chinese companies have very strict requirements on the claw breaking rate during the peeling process of chicken feet. More than 3%. [0003] In foreign countries, chicken feet are generally disposed of as waste, and even if they are processed, the rate of broken feet is not high. Therefore, chicken feet peeling equipment is seldom studied by people. [0004] At present, the existing chicken paw peeling equipment that poultry proc...

AI Technical Summary

Problems solved by technology

[0004] At present, the existing chicken paw peeling equipment that poultry processing plant uses has two kinds: a kind of is the chicken paw cleaning machine announced by CN2057555U, also known as the horizontal claw peeling machine. However, the rate of broken claws is as high as 5-7%. Due to the breakage rate of chicken feet, the product price is discounted, which brings great losses to the enterprises that use it; The claw rate does not exceed 3%, but the disadvantage is that it cannot be continuously produced, manual feeding and discharging are required, and the production efficiency is low
