Abstract
Abstract Apparatus for injecting seasoning and flavoring liquids into poultry meat composed of a storage reservoir or hydraulic accumulator from which fluid is pumped at a pressure between about 1,000 and 5,000 psi to injection nozzles under the control of a solenoid valve. Each solenoid valve is turned rapidly on and off by an electronic timer. As the nozzles are moved at the same speed of the meat to be injected, a high velocity jet of liquid lasting 0.1 to 0.5 seconds is shot from the nozzle into the meat and is dispersed in the tissue.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
232 words
A meat injection apparatus comprising in combination a supporting framework, a drive motor, a conveyor connected to the drive motor and mounted upon the framework for advancing the meat products from one end of the apparatus to the other, nozzles mounted intermediate the ends of the conveyor, said nozzles being supported for movement upon the framework upon axes parallel to the path of movement of meat products as they are carried through the apparatus by the conveyor, drive means operatively connected to the nozzles for moving the nozzles back and forth along the axes, the speEd of movement of the nozzles moving on said axis when traveling in the same direction as the meat products being on the same order as the speed of the meat products themselves and timing means operatively associated with the nozzles for opening the nozzles when the nozzles move in the same direction as the meat products, the meat products being given stable support by the conveyor at all times as they travel through the apparatus to thereby prevent excessive weep of injected liquid said nozzles being mounted upon the ends of longitudinally extending arms, the opposite ends of the arms being mounted upon the throw of a crank journalled for rotation upon a laterally extending axis and the drive motor being connected to the crank whereby the nozzles are moved back and forth along said axis.
Claim 2
Dependent Claim
232 words
A meat injection apparatus comprising in combination a supporting framework, a drive motor, a conveyor connected to the drive motor and mounted upon the framework for advancing the meat products from one end of the apparatus to the other, nozzles mounted intermediate the ends of the conveyor, said nozzles being supported for movement upon the framework upon axes parallel to the path of movement of meat products as they are carried through the apparatus by the conveyor, drive means operatively connected to the nozzles for moving the nozzles back and forth along the axes, the speEd of movement of the nozzles moving on said axis when traveling in the same direction as the meat products being on the same order as the speed of the meat products themselves and timing means operatively associated with the nozzles for opening the nozzles when the nozzles move in the same direction as the meat products, the meat products being given stable support by the conveyor at all times as they travel through the apparatus to thereby prevent excessive weep of injected liquid said nozzles being mounted upon the ends of longitudinally extending arms, the opposite ends of the arms being mounted upon the throw of a crank journalled for rotation upon a laterally extending axis and the drive motor being connected to the crank whereby the nozzles are moved back and forth along said axis.
Claim 3
Dependent Claim
39 words
The apparatus of claim 1 wherein a means is provided for periodically raising the nozzles to lift them away from the meat products when traveling counter to the direction of the travel of the meat products through the apparatus.
Claim 4
Dependent Claim
69 words
The apparatus of claim 1 wherein laterally extending nozzle elevating members are operatively associated with the arms for raising the nozzles periodically, a crank is operatively connected to the elevating members for raising the elevating members periodically in synchronization with the longitudinal movement of the arms, the elevating members being raised when the crank moves the nozzles counter to their direction of movement of the meat through the apparatus.
Claim 5
Dependent Claim
169 words
A meat injecting apparatus comprising a supporting framework, an endless belt conveyor for transferring meat products from one end of the apparatus to the other, drive means for the conveyor, guide mounted adjacent the conveyor and extending parallel thereto for defining at least first and second segregated channels for movement of the products from one end of the apparatus to the other upon the conveyor, a first set of nozzles mounted upon the apparatus for injecting fluid into meat products traveling along the first channel, a second set of nozzles for injecting meat products traveling along the second channel, means for increasing the quantity of expelled fluid for the first set of nozzles relative to the second set of nozzles whereby the first set of nozzles will inject a larger total quantity of liquid over a period of time than the second set of nozzles and the meat products traveling in the first channel will contain a greater level of injected liquid than those traveling in the second channel.
Claim 6
Dependent Claim
169 words
A meat injecting apparatus comprising a supporting framework, an endless belt conveyor for transferring meat products from one end of the apparatus to the other, drive means for the conveyor, guide mounted adjacent the conveyor and extending parallel thereto for defining at least first and second segregated channels for movement of the products from one end of the apparatus to the other upon the conveyor, a first set of nozzles mounted upon the apparatus for injecting fluid into meat products traveling along the first channel, a second set of nozzles for injecting meat products traveling along the second channel, means for increasing the quantity of expelled fluid for the first set of nozzles relative to the second set of nozzles whereby the first set of nozzles will inject a larger total quantity of liquid over a period of time than the second set of nozzles and the meat products traveling in the first channel will contain a greater level of injected liquid than those traveling in the second channel.
Claim 7
Dependent Claim
44 words
The apparatus according to claim 4 wherein said nozzles are spaced apart longitudinally of the apparatus and some of said longitudinally spaced apart nozzles are rendered inactive while others remain active thereby injecting a reduced total quantity of liquid over a period of time.
