Chicken processing method and chicken processing system

Abstract

The invention provides a chicken slaughtering and processing method for laying hens and a chicken slaughtering and processing system. The chicken slaughtering and processing method for laying hens includes: taking out live chickens from the farm cage, putting them into a plastic box, moving the plastic box, and loading it on a live chicken transport vehicle; mooring the above plastic box to a blue light with blocked external light Atmospheric mooring equipment; hanging the chickens contained in the above-mentioned plastic boxes on the hooks of the conveyor; passing the chickens through a stun machine, thereby being stunned by electricity with a gradually increasing voltage; bleeding steps; implementing scalding and depilation; passing the chickens through mowing head machine to cut off the chicken neck; pass the chicken through a flame machine to burn the chicken fluff; pass the chicken through the eviscerator to remove the giblets; ankle cutting step; cool the chicken in cooling water; ripen the chicken in the ripening chamber ; moving the chickens on belts and screening by weight; and packing the chickens.

Description

technical field [0001] The invention relates to a chicken slaughtering and processing method for laying hens and a chicken slaughtering and processing system. Background technique [0002] In general, chickens can be broadly classified into two types: chickens raised for eating chicken are called "broilers" and chickens raised for laying eggs are called "laying hens". [0003] When the growth period of broiler chickens (from feeding chicks to culling) is within 18 days to 40 days, the slaughter time varies according to different uses, while the growth period of layer chickens is within 1 year, 6 months to 2 years, if If the egg production rate drops below 65%, the farmers will slaughter the laying hens because of no profit. [0004] In the process of chicken slaughtering and processing, although the weight of the surviving 1.8kg broiler chicken and the surviving 1.8kg laying hen are the same, there are differences in the growth period, so the picking machine and picking met...

AI Technical Summary

Problems solved by technology

[0017] In this way, the conventional slaughtering and processing equipment includes the first line, the second line and the third line. After the processing of each line, the work of hanging the chickens on the next line is cumbersome, and thus there is a problem that it takes a lot of processing time.

[0018] In addition, conventionally, in order to hang the chicken whose ankles have been cut off on the first line on the hooks on the second line, it is necessary to hang the chicken knees on the hooks on the second line, so an expensive transfer machine is required, and there is a problem that a lot of equipment costs are required.

[0019] In addition, in the past, the total length of the usual first chain line, second chain line, and third chain line is 700-1950m (the first line is 300-600m, the second line is 200-350m, and the second line is 250-500m) , so there is a problem that the scale of the slaughterhouse needs to be large and the cost rises, which requires a lot of equipment expenses.

[0020] In addition, the structure of the conventional slaughtering and processing equipment is as follows, that is, if the chicken (chicken carcass) cooled by a chiller (chiller) is released after the internal organs are removed, it is immediately re-suspended on the third line and put in by weight. Therefore, the chicken There is a disadvantage that the incidence of damaged chickens increases due to the impact caused by the fall and fall, and the skin is bruised and so on.
