Abstract

Abstract A meat tendering machine particularly adapted to keep most of the blood within the meat and including a safety feature protecting against undesired access to the meat tendering rollers. This meat tendering machine includes a base, a hollow column mounted on the base, a casing projecting in cantilever fashion from the hollow column, a pair of meat tendering rollers in the casing and removably engaging with a drive in the hollow column, and meat tendering teeth on the periphery of the rollers. The meat tendering teeth of each roller are disposed in a plurality of annular rows, the teeth in any one row being spaced from one another circumferentially of the roller by intervening notches having a convex bottom coinciding with the cylindrical outer face of the roller, the teeth of each second row being in substantial register longitudinally of the roller, the teeth of any one row being in substantial register with the notches of adjacent rows longitudinally of the roller, the several rows being spaced from one another longitudinally of the roller by an intervening annular zone. The teeth of one roller are staggered relative to the teeth of the other roller, such that the teeth of one roller engage the annular zone of the other roller, and vice versa. The teeth of one roller, when engaging said annular zones of the other roller, are in register with the teeth of the other roller longitudinally of the rollers, the teeth of the two rollers cooperatively formed with the annular zones, meat holding cavities in which the meat is not subjected to the compression effect of the teeth, and wherein the blood from the compressed meat zones can flow.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 358 words
A meat tenderizing machine comprising a pair of cylindrical rollers extending alongside each other, drive means connected to the rollers and counterrotating the latter at the same speed, each roller having similar meat tenderizing teeth projecting outwardly at the periphery thereof and disposed in annular rows with the teeth equally separated by intervening free spaces within said annular rows and with the bottom of said free spaces substantially coinciding with the outer cylindrical surface of the roller, the annular rows of teeth being spaced axially of the roller to define free annular zones between the annular rows of each pair of annular rows, the teeth of each second annular row of any one roller being in substantial register axially of the roller, the teeth of any one annular row of any one roller being in substantial register with the intervening free spaces of adjacent annular rows axially of the roller, the teeth of one roller engaging the annular zones of the other roller and the teeth of the other roller engaging the annular zones of the one roller, the teeth of any one roller, when fully engaging the annular zones of the other roller, being, axially of the roller, in register with, close to but out of contact with, a tooth of the other roller on one side of said teeth and being, axially of the roller, in register with one intervening free space and with one annular zone of the other roller, on the other side of said teeth, the width of the teeth of any one roller, axially of the roller, being smaller than the sum of the widths of said intervening free space and of the adjacent annular zone and being greater than the space separating said teeth from the teeth of the other roller on said one side, this registering intervening space and adjacent annular zone defining a meat holding cavity wherein meat is free of compression by the teeth to enable flowing into the portion of the meat in said cavity of the internal blood of the meat compressed out by the action of the teeth on the remaining zones of the meat.
Claim 2
Dependent Claim 358 words
A meat tenderizing machine comprising a pair of cylindrical rollers extending alongside each other, drive means connected to the rollers and counterrotating the latter at the same speed, each roller having similar meat tenderizing teeth projecting outwardly at the periphery thereof and disposed in annular rows with the teeth equally separated by intervening free spaces within said annular rows and with the bottom of said free spaces substantially coinciding with the outer cylindrical surface of the roller, the annular rows of teeth being spaced axially of the roller to define free annular zones between the annular rows of each pair of annular rows, the teeth of each second annular row of any one roller being in substantial register axially of the roller, the teeth of any one annular row of any one roller being in substantial register with the intervening free spaces of adjacent annular rows axially of the roller, the teeth of one roller engaging the annular zones of the other roller and the teeth of the other roller engaging the annular zones of the one roller, the teeth of any one roller, when fully engaging the annular zones of the other roller, being, axially of the roller, in register with, close to but out of contact with, a tooth of the other roller on one side of said teeth and being, axially of the roller, in register with one intervening free space and with one annular zone of the other roller, on the other side of said teeth, the width of the teeth of any one roller, axially of the roller, being smaller than the sum of the widths of said intervening free space and of the adjacent annular zone and being greater than the space separating said teeth from the teeth of the other roller on said one side, this registering intervening space and adjacent annular zone defining a meat holding cavity wherein meat is free of compression by the teeth to enable flowing into the portion of the meat in said cavity of the internal blood of the meat compressed out by the action of the teeth on the remaining zones of the meat.
Claim 3
Dependent Claim 72 words
A meat tenderizing machine as claimed in claim 1, wherein each tooth has a substantially rectangular base with its longer dimension extending annularly of the roller and each tooth tapering radially outwardy and terminating in a blunt end, the inter-engaging teeth of both rollers leaving free spaced therebetween and the blunt ends of the teeth of any one roller leaving a free space with the outer cylindrical surface of the other roller.
