Slaughtering and processing device and slaughtering and processing method for chilled chicken

Abstract

The invention discloses a slaughtering and processing device and slaughtering and processing method for chilled chicken. The method comprises the following steps: manually fixing chicken on a hook ofa conveying device; sending the hung chicken into a stunning and killing device through the hook and the conveying device for welfare slaughtering, draining blood after slaughtering, and then performing soaking, scalding and unhairing, and sending the treated chicken into a first cleaning tank for cleaning; performing evisceration to remove internal organs after cleaning, and then performing cleaning again; and sending the chicken into a bone removing device to remove the head and feet after cleaning, sending the chicken into a cooling tank for pre-cooling, and sending the chicken into a low-temperature freezing box after per-cooling. The slaughtering and processing method is clean and rapid, ensures sanitation of slaughtering sites, reduces bacterial colony on the chicken, and avoids chicken taste deterioration caused by the huge change from the high temperature for unhairing to the freezing temperature, breeding of bacteria is prevented by a plasma electrostatic field, and the purpose of continuous insurance is achieved. Moreover, juice loss and surface browning are avoided, quality is ensured, the shelf life is prolonged, and the slaughtering and processing method has wide applicability in the field of chicken processing.

Description

technical field [0001] The invention belongs to the field of food processing, in particular, the invention relates to a processing device for chicken. Background technique [0002] Chicken, duck, and goose are one of the poultry that is often eaten in daily life. With the continuous improvement of living standards, chicken is the second largest meat product in the world after pork, maintaining an annual consumption growth rate of 3%. However, traditional artificial Slaughtering, scalding and hair removal can no longer meet the needs of the society. Poultry slaughtering lines have been widely used. The slaughtering lines are made of stainless steel, which has a high degree of automation, stable performance, simple and convenient operation, time-saving and labor-saving, safe and convenient, and long service life. The slaughter of poultry forms factory production, which greatly improves the efficiency of poultry slaughter and meets people's demand for poultry meat products. ...

AI Technical Summary

Problems solved by technology

[0006] The present invention aims at the technical problems of juice loss, surface browning, and serious pollution caused by incomplete cleaning of chilled meat in the chicken slaughtering line in the prior art. The present invention provides a chilled chicken slaughtering and processing device and its slaughtering and processing method. Through reasonable design of the slaughtering and cleaning process, and the use of immersion cooling to clean and cool the chicken, the ketone body of the chicken is pre-cooled, avoiding the temperature change from depilation to quick freezing, which will cause the juice in the meat to crystallize and lock the meat in the body. To avoid the loss of juice, plasma sterilization and electrostatic field freezing are used at the same time during the low-temperature freezing process to decompose the negatively charged bacteria on the surface of the chicken and prevent the growth of bacteria to achieve the effect of continuous insurance. It is widely applicable in the field of poultry meat processing sex
