Abstract
A poultry stunning apparatus and method, the apparatus including an electrical control module configured to apply a DC current to the poultry at a voltage sufficient to stun the poultry and to apply AC current to the stunned poultry at a user-selectable voltage, current level, and/or frequency and for a period of time sufficient to immobilize and relax the muscles of the stunned poultry, while at the same time avoiding or minimizing damage to the poultry tissue.
Claims20
A poultry stunning apparatus, comprising:
- an electrical control module configured to apply a DC current to the poultry at a stunning voltage to stun the poultry and to apply immobilizing AC current to the stunned poultry at a voltage and for a period of time to immobilize and relax the muscles of the stunned poultry, while at the same time avoiding or minimizing damage to the poultry tissue, wherein the electrical control module is operative to apply the AC current at a selectable variable amperage and/or selectable variable frequency, wherein the AC current is applied at a selectable voltage of between 60 VAC and 250 VAC and wherein the AC voltage/current is applied at a frequency of 200-400 Hz.
A poultry stunning apparatus, comprising:
- an electrical control module configured to apply a DC current to the poultry at a stunning voltage to stun the poultry and to apply immobilizing AC current to the stunned poultry at a voltage and for a period of time to immobilize and relax the muscles of the stunned poultry, while at the same time avoiding or minimizing damage to the poultry tissue, wherein the electrical control module is operative to apply the AC current at a selectable variable amperage and/or selectable variable frequency.
