SANITARY CUTTING APPARATUS, SYSTEM AND METHOD FOR PRE-COOKED MEAT PRODUCTS
A vertical cutting apparatus for cooked meat products which can be installed on the outlet of a spiral oven or other heating apparatus for directly receiving and cutting the cooked product in sterile condition while still hot in order to prevent cross-contamination of either the (a) sliced, cubed, diced, or shred cut product or (b) the cutting apparatus. The hot product can also be delivered directly from the vertical cutting apparatus into its final product packaging and immediately vacuum seal for further product safety.
1 . An apparatus for vertically cutting a food product comprising:
a housing having an upper product inlet opening;
a cutting head driveably installed in the housing for driven rotation of the cutting head in a cutting direction;
a roller rotatably installed in the housing adjacent and parallel to the cutting head;
an upwardly facing product receiving nip formed between the cutting head and the roller; and
a vertical cutting path defined in the apparatus which travels downwardly into the upwardly facing product receiving nip and then continues downwardly between the cutting head and the roller.
2 . The apparatus of claim 1 further comprising a drive motor which drives the cutting head in the cutting direction.
3 . The apparatus of claim 1 wherein the cutting head comprises a series of radially extending circular cutting blades.
4 . The apparatus of claim 3 wherein:
the radially extending circular cutting blades have outer circular cutting edges and
the roller comprises a series of circular exterior grooves corresponding to the series of circular cutting blades for receiving the outer circular cutting edges of the circular cutting blades as the outer circular cutting edges meet the roller at the upwardly facing product receiving nip.
5 . An assembly for cutting a sterile cooked meat product comprising;
a heating apparatus having a product outlet and
a vertical cutting apparatus installed on the heating apparatus beneath the product outlet of the heating apparatus, wherein the vertical cutting apparatus comprises:
a housing having an upper product inlet opening;
a cutting head driveably installed in the housing for driven rotation of the cutting head in a cutting direction;
a roller rotatably installed in the housing adjacent and parallel to the cutting head;
an upwardly facing product receiving nip formed between the cutting head and the roller; and
a vertical cutting path defined in the vertical cutting apparatus which travels downwardly into the upwardly facing product receiving nip and then continues downwardly between the cutting head and the roller.
6 . The assembly of claim 5 wherein the heating apparatus is an oven.
7 . The assembly of claim 6 wherein:
the oven has a product conveyor for carrying product through the oven;
the product conveyor has an outlet end which projects from the product outlet of the oven; and
the outlet end of the of the product conveyor is positioned above the upper product inlet opening of the vertical cutting apparatus and above the upwardly facing product receiving nip formed between the cutting head and the roller.
8 . The assembly of claim 5 wherein the heating apparatus is a spiral oven.
9 . The assembly of claim 8 wherein:
the spiral oven has a conveyor therein for carrying product upwardly through the oven in a spiral pattern;
the conveyor has an outlet end which projects from the product outlet of the spiral oven; and
the outlet end of the of the conveyor is positioned above the upper product inlet opening of the vertical cutting apparatus and above the upwardly facing product receiving nip formed between the cutting head and the roller.
10 . The assembly of claim 9 further comprising:
an exterior hood positioned over the product outlet of the spiral oven and
a shield structure which extends upwardly from the vertical cutting apparatus to substantially enclose a bottom opening of the exterior hood.
11 . The assembly of claim of claim 8 wherein the vertical cutting apparatus is movably installed on the spiral oven for movement from an operating position beneath the product outlet of the spiral oven to a non-operating position removed from the product outlet of the spiral oven.
12 . A method of producing a pre-cooked meat product comprising the steps of:
delivering a meat product through a heating apparatus to a product outlet of the heating apparatus and
cutting the meat product into separate smaller pieces by delivering the meat product vertically downward from the product outlet of the heating apparatus through a vertical cutting apparatus positioned below the product outlet of the heating apparatus.
13 . The method of claim 12 wherein, in step (b), the meat product is received from the product outlet of the heating apparatus through a top opening of the vertical cutting apparatus and travels vertically downward through the vertical cutting apparatus to a bottom discharge opening of the vertical cutting apparatus.
14 . The method of claim 12 wherein
the heating apparatus has an product conveyor which conveys the meat product through the heating apparatus;
the product conveyor has an outlet end which projects from the product outlet of the heating apparatus; and
the outlet end of the of the product conveyor is positioned above a top opening of the vertical cutting apparatus.
15 . The method of claim 12 wherein the meat product delivered through the heating apparatus in step (a) is a cooked meat product and the heating apparatus is a surface pasteurizer which kills pathogens on an outer surface of the cooked meat product.
16 . The method of claim 12 wherein the heating apparatus is an oven in which the meat product is cooked in step (a).
17 . The method of claim 16 wherein the heating apparatus is a spiral oven.
18 . The method of claim 16 wherein the separate smaller pieces of the cooked meat product produced in step (b) are discharged directly from the vertical cutting apparatus into product packages.
19 . The method of claim 18 wherein the product packages into which the separate smaller pieces of the cooked meat product are discharged are next vacuum sealed without being further processed prior to sealing.
20 . The method of claim 18 wherein, after the separate smaller pieces of the cooked meat product are discharged into the product packages, a sauce or marinade is next added to the product packages and the product packages are then vacuum sealed without being further processed prior to sealing.
