Apparatus and method for automatically removing neck skin of poultry

Abstract

The invention relates to an apparatus and method for automatically removing neck skin of poultry. The apparatus comprises the following components: a suspension hook for reversing a chicken body with a back part outward; a device for separately fixing legs and a device for fixing a chest for fixing the chicken body; a wing holding apparatus for supporting chicken wings and leading the chicken body; a cutting knife apparatus for cutting a root part of the neck; a neck skin removing hand apparatus for fixing the chicken neck and tearing the neck skin downward; an inner track and an outer track for adjusting closure of the neck skin removing hand apparatus and up-and-down motion; an inner blocking rod of the suspension hook and an outer blocking rod of the suspension hook for adjusting suspension hook positions according to size of the chicken body. The apparatus and the method can be used for automatically separating the neck skin and the neck simultaneously on line, tracheae, oesophaguses and craws remain on the chicken necks and are pulled out with internal organs later, so that damages to neck skin and necks during subsequent processing of remaining tracheae, oesophaguses and craws of chickens are prevented.

Description

technical field [0001] The invention belongs to the field of poultry slaughtering and processing, and specifically relates to a device and method for performing on-line automatic neck skin removal on chicken bodies before automatic evisceration. Background technique [0002] Food safety regulations require that during poultry evisceration, the crop, trachea, esophagus, and lymph should be completely removed. [0003] Because the customs and habits of our country are different from those of developed countries, especially the neck, neck skin, crop and trachea of ​​poultry can be processed into by-products, and there is a certain market. In developed countries, the neck, neck skin, crop, and trachea are all treated as waste. Therefore, when using automated equipment, there is no need to consider the damage and weight loss caused by the equipment to the poultry neck. The current division method in China is the hanging neck division, and the neck must be preserved during the ev...

AI Technical Summary

Problems solved by technology

This method, used in developed countries for waste can, in China, does not meet the requirements of the evisceration process to retain the neck

Moreover, after the equipment separates the neck from the skin, a lot of manpower is needed to pick out the crops, esophagus, and trachea.

[0007] The third method is to squeeze and break the neck, separate it from the poultry carcass, and then cut the neck skin, such as US4091503, US4184230, NZ221946A, and US3965534.

The crops are damaged at the same time, and the crops flow out, causing pollution to the chicken body, which does not meet the food safety regulations
