Apparatus for injecting fluid into meat products
View Patent ↗A method for injecting fluid into meat products comprises taking a plurality of hollow fluid injection needles having sharpened discharge ends, and connecting the needles to a source of pressurized liquid; penetrating the sharpened ends of the needles into the product and thence withdrawing the same while discharging fluid into the product and vibrating the needles for a period of time while they are within the product to enlarge the size of a penetration hole within the product caused by the penetration of the needles to a size greater than the size of the needles to create at least a partial space around the needles to permit fluid from the needles to migrate into the spaces around the needles. The needles have a roughened outside surface.
1. A meat injection machine comprising a frame,
an injection head having a plurality of downwardly extending hollow fluid injection needles having sharpened lower fluid discharge ends to penetrate a meat product for injecting fluid therein, with a source of pressurized fluid connected to the needles, the invention comprising,
a vibrating mechanism on the machine operatively connected to the needles to cause the needles to vibrate laterally as they penetrate a meat product to create at least a partial space around the needles to permit fluid from the needles to migrate into the spaces around the needles to facilitate the dispersion of the fluid into the meat product.
2. The meat injection machine of claim 1 wherein the needles have a roughened outside surface to facilitate the creation of the enlarged size of the penetration hole.
