[0040] First embodiment (handling method for slaughtering animals)

[0041] In this embodiment, the above-mentioned conventional processing steps are adopted, and the voltage waveform is changed in the electrical stimulation application step S41b, and by this change, the time required for maturing the slaughtered animal can be shortened from about four hours to half a day required by the conventional processing method to about two hours, and can obtain the same results as traditional methods. The first embodiment of the treatment method of the present invention includes a transporting step and an electrical stimulation applying step. The transporting step is for transporting a carcass that has undergone the treatment of the evisceration step S40 and is in a state before and during the onset of stiffness, wherein the carcass is in the state of stiffness. Applying an electrical stimulation voltage having a plurality of voltage application cycles of different application duration...

[0045] Second embodiment (processing method for slaughtering animals)

[0046] In this embodiment, a second electrical stimulation application step is also provided after the cooling step (low temperature cooling step) S42a and before the thigh cutting step S42b. That is, this embodiment of the processing method includes the step of removing the internal organs, the first electric stimulation application step of applying electric shocks to the slaughtered animals in the state before the onset of stiffness and the state of the stiffness process, the low-temperature cooling step, and the cooling step after the cooling step. A second electrical stimulation application step of applying an electric shock to the slaughter animal. The electrical stimulation voltage application pattern in each electrical stimulation application step can be determined to optimize the electrical stimulation effect.

Abstract

The present invention discloses a device and method for processing meat carcass. In order to shorten a long aging time required for meat processing and reducing the viable cell count of a carcass before cooked, an electric stimulus is imparted by applying an ac voltage from electrode rails (1, 2, 3) to the neck, chest and legs of the meat carcass respectively. The ac voltage is turned on for a time Ton and then turned off for a time Toff and the application of the voltage is repeated a predetermined number of cycles. Ton is not longer than Toff, the voltage is not higher than 100V and the frequency is not higher than the commercial frequency (maximum, 60 Hz). A needle (51) for chest is supported by a metal support (52) and brought into pressure contact with the electrode rail (2), and a needle (53) for neck is supported by a metal support (54) and brought into pressure contact with the electrode rail (1) through a meal support (57). Legs of the meat carcass are energized by the electrode rail (3). Aging effect is improved by stimulating the entire meat carcass electrically from at most three points.

Description

technical field [0001] The present invention relates to an apparatus and method for treating carcass, and more particularly to an apparatus and method capable of reducing the time required for aging and sanitizing poultry carcass for consumption, and more particularly to A device and method for shortening the aging time and reducing the viable cell count by applying electric current before and during rigor mortissets in sets in. Background technique [0002] Traditionally, edible poultry is stunned, often by electric shock, and then bled, scalded in boiling water, plucked, eviscerated, cooled, and aged at low temperature for a long period of time. In the traditional method, the carcass is usually scalded with boiling water to make hair removal easier. Then, the slaughtered animal is shaved, and the internal organs are removed. At evisceration, the temperature of the carcass is often reduced to about 4.4°C by cooling it in a pool of ice or cold water due to concerns about t...
