Abstract: A portable apparatus having a tank having an internally treated surface for containing at least 500 liters, a pump connected to the exit of the tank for pumping solution to a nozzle through a reducing coupling, a water meter means for controlling the quantity of solution entering the steer, a cut-off valve at the water meter, and a cut-off valve at the nozzle, a manometer means for reading pressure passing through the system which is substantially equal to or greater than the pressure developed in the animal's arterial system, and a return pipe from the pump to the tank. By means of the present invention there is provided means for injecting solution into a slaughtered animal when a veterinarian, who controls the quantity of the solution administered according to the weight of the animal such as a steer, and, when the appropriate amount of solution has entered and passed through the steer, the veterinarian closes his valve and the nozzle is shut and removed from the slaughtered animal.

Abstract: A method for injecting an additive material into the flesh of a poultry carcass by inserting a comb-like instrument comprising a hollow manifold and a plurality of hollow tines extending therefrom, longitudinally of a poultry carcass between the skin and flesh, thereof, and the tines are forced into the flesh without penetrating the skin. Thereafter, a liquid additive is forced through the manifold and tines and through orifices therein and ejected into the flesh.

Abstract: An injection system for injecting a liquid material into a meat product comprises a double acting pneumatic drive cylinder, an injection cylinder the piston of which is connected to the piston of the drive cylinder and at least one injection needle connected to an outlet valve from the injection cylinder. A first stop member is fixed relative to the drive piston and a second stop member is fixed relative to the cylinder and there is an air supply control means that is actuated when the first stop member meets the second stop member to reverse the air supply to the drive cylinder.
