Abstract

The invention discloses a frequency and voltage modulation device and method for a poultry electric stunning device. The frequency and voltage modulation device comprises a three-phase voltage isolation transducing unit (1), a three-phase bridge-type rectifying circuit (2), a DC / DC double-path direct-current power outputting module (3), a voltage modulation controlling unit (4), a PLC (Programmable Logical Controller) functional module (5), an upper computer controlling system (6), a frequency modulation controlling unit (7), a direct-current pulse outputting module (8), a liquid crystal display unit (9) and a direct-current pulse output controlling unit (10). According to the technical scheme of the invention, a novel frequency and voltage modulation technical scheme is provided; as high-frequency and low-voltage direct-current pulse electric output is adopted, the speed of electric stunning is high, and requirements of a slaughter assembly line are satisfied; meanwhile, wing breaking and extravasated blood of poultry caused by nervous flapping can be reduced, bleeding is facilitated, and the sanitation safety of meat products and the reliability of the production quality are ensured.

Description

Technical field

[0001] The invention relates to the field of poultry electric hemp machines, in particular to a frequency and voltage regulation device and method for poultry electric hemp machines. Background technique

[0002] With the improvement of economic conditions, consumers' requirements for poultry products have also been further improved. They not only require meat products to be safe and nutritious, but also have better taste and flavor. Pre-slaughter stress has a certain effect on meat quality. Pre-slaughter stunning can make animals feel no pain during the slaughter process, so as to reduce the pre-slaughter stress of animals and improve meat quality.

[0003] At present, on the poultry slaughter line, most companies use water bath electric stunning to stun the poultry. When the hanging poultry passes through the electric hemp machine, the head of the bird touches the water and connects with the fire line, and the claws pass through the contact guide rod. Connect wit...
