Method for slaughtering poultry through electric shock and variable-frequency electric anesthesia machine

Abstract

The invention discloses a method and a device for slaughtering poultry through the electric shock. The device comprises a control system, a bridge rectifier circuit, an output adjusting circuit and a frequency adjusting circuit, wherein a data server and a plurality of PWM (Pulse Width Modulation) controllers in communication connection with the data server are arranged in the control system, the bridge rectifier circuit comprises a drive part and a rectification part connected with an electrical bridge, the output adjusting circuit comprises an adjusting end detection circuit, a voltage detection circuit, an overvoltage reference circuit and an overvoltage protection circuit, and the frequency adjusting circuit comprises a register and a microprocessor. Through the adoption of the device and the method disclosed by the invention, to-be-slaughtered poultry on a production line can be automatically and accurately identified and tracked, the sanitary safety of meat products and the reliability of the production quality are ensured, and meanwhile, the production efficiency is improved greatly.

Description

technical field [0001] The invention relates to poultry slaughtering and processing industry, in particular to a method and equipment for slaughtering poultry by electric shock. Background technique [0002] With the rapid development of the poultry processing industry, the poultry processing output has reached a capacity of 12,000 per hour, and the slaughtering capacity of a large poultry slaughtering factory has reached 120,000 per day. With such a large number of poultry, domestic and foreign poultry processing industries have already set their goals on the modularization and flexibility of equipment production and the informatization of production management and product quality control. According to the modular concept of slaughtering and processing equipment, the slaughtering and processing process is divided into eight modules: live poultry receiving, electric anesthesia slaughtering, viscera processing, cooling, cutting, deboning, measuring and packaging, and quality ...

AI Technical Summary

Problems solved by technology

All three types of electric anesthesia machines can realize the stunning slaughter of poultry, but in the long-term practical application, it was found that during the slaughter process, due to the different number of birds in the water tank, when the three types of electric anesthesia machines were used for electric anesthesia, the poultry passed through. The amount of current varies, so that sometimes the birds will not be stunned, or there will be congestion

[0006] The utility model patent with the Chinese patent announcement number CN202122049U discloses an electric anesthesia device for poultry slaughtering. This electric anesthesia device uses high-frequency voltage, and the frequency and voltage can be adjusted depending on the livestock. Although it improves the disadvantages of the previous fixed voltage output, However, its shortcomings are still obvious: it is impossible to achieve precise electric anesthesia slaughter according to the number of livestock in the same tank to ensure that the current is consistent, and the problem of livestock bloodletting standards is still unsolved
