Abstract
This invention relates to an apparatus for injecting a fluid substance into a portion of meat. In particular, this invention relates to an apparatus for injecting a fluid substance having a paste-like consistency through needles into a portion of meat wherein a uniform dose of fluid is injected through each needle.
Claims8
A machine for injecting a fluid substance into a portion of meat comprising;
- (a) a needle support base,
- (b) a plurality of injection needles each having a proximal end mounted in said needle support base and a distal end projecting from said needle support base, each of said needles having an injection passage opening longitudinally therethrough from its proximal end to its distal end,
- (c) a fluid manifold chamber in said needle support base for receiving the fluid substance,
- (d) a plurality of dosage chambers in said needle support base, one of said dosage chambers being associated with each needle for supplying an individual dose of fluid to its associated needle,
- (e) one-way flow control means between the fluid manifold chamber and each dosage chamber and between each dosage chamber and the injection passage of its associated needle, said one-way flow control means being operable to permit fluid to pass from the manifold chamber into each dosage chamber while preventing the passage of fluid from each dosage chamber through the injection passage of its associated needle and to prevent the passage of fluid from the fluid manifold chamber into the dosage chambers while permitting fluid to pass from the dosage chambers through the injection passages of the needles whereby substantially uniform predetermined dosages of fluid are dispensed through each injection needle during injection.
In a machine for injecting a fluid substance into a portion of meat, a plurality of injection needles mounted in a support base, each needle having an injection passage opening therethrough which has an input end and a discharge end, first passage means in the needle support base for supplying a fluid substance to said needles for injection therethrough and closure means normally closing the input end of each needle, the improvement of;
- (a) a plurality of dosage metering chambers formed in said needle support base, each needle having a dosage metering chamber associated therewith,
- (b) one-way means for admitting said fluid substance from said first passage into each metering chamber to fill each metering chamber with a predetermined dosage of said fluid substance, said
- (c) means for expelling said predetermined dosage of fluid substance from each dosage metering chamber and opening said closure means of the injection needle which is associated therewith to discharge the predetermined dosage through said associated injection needle.
