The present invention relates to a system and method for manufacturing processing a food product.
It is known to produce large quantities of a food product by forming the food product in a mold, then (for certain food products) partially or fully cooking the food product, and then slicing the food product into desired portions or quantities. Such food products included, for example, meat, sausage, ham, cheese and the like.
Devices and methods are generally known for slicing such food products. For example, a cutting apparatus or slicer cuts the products into slices and then transports the sliced portions away for further processing (e.g., packaging) from a collection area adjacent to the slicing apparatus. Some known devices move one or more elongated segments of the food product (e.g., “logs” or “loaves”) through similarly shaped apertures in a cutting head to be sliced by a blade. These food product logs typically have circular, rectangular, or semi-circular cross-sections.
However, such food products are not configured for improving efficiency of the slicing operation. For example, the amount of food product sliced per movement (e.g., rotation) of the blade is a metric representative of the efficiency and costs associate with the food manufacturing operation. The known cross-sections leave an undesirable amount of area unoccupied by food products. Accordingly, it would be advantageous to provide a slicing operation that slices more food product per movement of the blade to improve efficiency and reduces costs. It would also be advantageous to provide the food product in a shape that more efficiently uses the space available to be cut (i.e., occupies most of the cutting zone). It would be desirable to provide for a food product processing method and apparatus having one or more of these or other advantageous features. To provide an inexpensive, reliable, and widely adaptable food product processing method and apparatus that avoids the above-referenced and other problems would represent a significant advance in the art.
The present invention relates to a food product formed in a mold to undergo cooking and processing operations. The food product includes an elongated body having a longitudinal axis, a first side providing a substantially planer surface, a second side extending substantially perpendicular to the first side, a third side extending substantially perpendicular to the first side and substantially parallel to the second side, and a fourth side extending between the second side and the third side and having a convex curvature extending away from the first side. The first side, second side, third side, and fourth side form a substantially D-shaped cross-section taken perpendicular to the longitudinal axis.
The present invention also relates to a method for slicing elongated food products into a plurality of slices with a slicing apparatus that is coupled to a product supply system. The slicing apparatus provides a cutting zone defined at least partially by a cutting head and by a range of movement of a cutting element. The method includes the step of providing a first food product, a second food product, a third food product, and a fourth food product. Each of the food products has an elongated body and an longitudinal axis, a first side providing a substantially planer surface, a second side extending substantially perpendicular to the first side, a third side extending substantially perpendicular to the first side and substantially parallel to the second side, and a fourth side extending between the second side and the third side and having a convex curvature extending away from the first side. The first side, second side, third side, and fourth side form a substantially D-shaped cross-section taken perpendicular to the longitudinal axis. The method also includes the step of arranging the first, second, third, and fourth food products in a series laterally across the cutting zone so that first food product and the fourth food product are located at the outer portion of the cutting head, the second food product is located between the first food product and the third food product, and the third food product is located between the second food product and the fourth food product. The method also includes the step of orientating the fourth side of the first food product and the fourth side of the fourth food product to face in an opposite direction from each other that is outward and away from the second food product and third food product. The method also includes the step of moving the cutting element to slice the food products.
The present invention further relates to an apparatus for slicing a plurality of food products. Each food product has an elongated body having a longitudinal axis, a first side providing a substantially planer surface, a second side extending substantially perpendicular to the first side, a third side extending substantially perpendicular to the first side and substantially parallel to the second side, and a fourth side extending between the second side and the third side, and having a convex curvature extending away from the first side. The first side, second side, third side, and fourth side form a substantially D-shaped cross-section taken perpendicular to the longitudinal axis. The improvement includes a cutting head having a plurality of “D”-shaped apertures. Each “D”-shaped aperture is configured to receive one of the “D”-shaped food products. The improvement also includes a cutting element with a cutting edge configured to move through a cutting path adjacent the cutting head. The D-shaped apertures occupy a substantial portion of the cutting zone.
The present invention further relates to a system for manufacturing a food product. The system includes a plurality of food product molds. The system also includes a food product cooking system having plurality of tanks configured to receive the food product molds and to cook the food products within the molds using a heated water solution. The system also includes an apparatus to unload food product logs from the food product molds and onto a first conveying system. The system also includes a buffering and equilibrating apparatus coupled to the plurality of tanks by the first conveying system, and configured to cool core temperatures of the food product logs to a predetermined temperature. The system also includes a slicing apparatus configured to receive food products logs from the buffer and equilibrating apparatus by a second conveyor system and configured to slice the food product logs into a plurality of slices. The cycle time for cooling the food product logs is greater than the cycle time for slicing the food product logs. The buffering and equilibrating apparatus is further configured to compensate for the difference in cycle times between the food product cooking system and the slicing apparatus.
The present invention further relates to various features and combinations of features shown and described in the disclosed embodiments. Other ways in which the objects and features of the disclosed embodiments are accomplished will be described in the following specification or will become apparent to those skilled in the art after they have read this specification. Such other ways are deemed to fall within the scope of the disclosed embodiments if they fall within the scope of the claims which follow.

Molds 102 are generally configured to receive food materials or ingredients and form, compact, press, or squeeze them into a defined shape, for example a D-shape. Food product cooking system 104 typically includes one or more processing tanks 105 and is configured to receive molds 102 and wash and cook the food product in molds 102 using a heated water solution. According to various exemplary embodiments, the heated water solution may be any water-based solution capable of washing and cooking the food products when heated. Apparatus 106 then unloads the formed food product logs from molds 102 onto first conveyer system 108. First conveyor system 108 transports the food product logs to buffering and equilibrating system 110.
Buffering and equilibrating system 110 may be configured to chill/cool the core temperatures of the food product logs to a predetermined temperature. Buffering and equilibrating system 110 may also provide for more efficient transport of the collected food product logs to slicing apparatus 114 via second conveyor system 112. Slicing apparatus 114 receives the food product logs and slices them into a plurality of slices, which may then be packaged and shipped for sale and/or use. According to one exemplary embodiment, the cycle time cooking the food product or for cooling the food product log in buffering and equilibrating system 110 may be greater than the cycle time for slicing the food product logs in slicing apparatus 114. According to other exemplary embodiments, the cycle time for cooling the food product log in buffering and equilibrating system 110 may be less than or equal to the cycle time for slicing the food product logs in slicing apparatus 114. To prevent back-log of food product or down time for an apparatus, the buffer correlates the operating rates for a continuous and efficient operation.

In raw manufacturing process 208, binder materials and meat (e.g., whole muscles) are processed in parallel. The binder materials are emptied out of containers by a dumper 222. A screw loader or auger 224 then meters out the materials to roughly a specific portion. A metering belt and metal detector 226 meter the materials more finely so that the individual pieces can be scanned for foreign material contamination (e.g., metal). A fine grinder/emulsifier 228 then reduces larger pieces of fresh or frozen materials to smaller pieces, for example approximately three-eighths of an inch in diameter. The materials are then deposited into a storage hopper 232 by a dumper 230 for later processing.
Similar to the binder materials, the meat is emptied out of containers by a dumper 234. A screw loader or auger 236 then meters out the meat to roughly a specific portion. A metering belt and metal detector 238 meter the meat more finely so that the individual pieces can be scanned for foreign material contamination. An injector 240 pumps liquid brines into the meat to provide flavoring and enable the curing process. A masscerator 242 cuts slits into the raw meat to create more surface area for protein to form. The materials are then deposited into storage hopper 232 by a dumper for later processing.
Any fresh and dry materials are processed in dual pickle making systems 206, for example using a polar induction system, are also deposited in storage hopper 232. Polar massagers 244 are used to extract protein from the binder materials and meat in storage hopper 232 to facilitate binding of the individual pieces of meat. The meat is then stored in a storage hopper 246 for use by a stuffing process 248.
Meat is transferred from storage hopper 246 of raw manufacturing process 208 to stuffing process 248 via a pipeline 250. A vacuum load hopper 252 receives the transferred meat and acts as a storage buffer for stuffing process 248. A portion element 254 (e.g., a Handtmann HVF 670 available from Handtmann Inc. of Buffalo Grove, Ill. or a Marlen Opti 340 available from Marlen Research Corp of Shawnee Mission, Kans.) is configured to pump and portion raw meat into a plastic casing. A [pipeline metal] detector 256 scans the pumped product for metal contamination and may reject product when it senses a foreign material (e.g., metal) in the meat. A casing element 258 forms a casing from flat material and it rolls it into a tube with a welded seam so that the meat can be stuffed into it. A crimper 260 cuts the formed casing from above and seals the ends of the casing by attaching a metal clip that crimps both ends of the stuffed casing. A dual lane check scale 262 weighs the stuffed casing and rejects any stuffed casing that is out of specification for a given weight range.
A material handling process 264 receives stuffed logs from stuffing process 248 via a conveyor 266. A D-shaped log roller 268 rolls the stuffed casings into a D shape and a mold loader 270 loads the D-shaped logs into molds 102 for thermal processing.
In a thermal processing system 272, a conveyor/crane 274 loads the molds into a thermal processing tank 105. In the processing tank, the molds are first heated in a step 276 by hot water pumped from storage tanks 278 to cook the meat. At a step 280, tanks 105 and meat are pre-cooled by introducing cold water from a storage tank 282 into tanks 105. At a step 284, tanks 105 and the meat are chilled using a cold salt brine from a storage tank 286. At a step 288, a suction device removes the cooked and chilled logs from the molds. At a step 290, the empty molds are washed and sanitized for reuse. The clean molds are then sent to a mold storage magazine 292 for storage. At a step 294, the demolded logs are rinsed and conveyed to buffering and equilibrating system 110.
Buffering and equilibrating system 295 is configured to distribute logs to individual clean rooms and act as a buffer to equalize the differences in production rates between thermal processing system 272 and slicing apparatus 114. In the illustrated exemplary embodiment, buffering and equilibrating system 295 includes four sequential buffers 296 with five tiers and 42 logs per tier. A four tier conveyor 298 transfers the logs to clean rooms for slicing. It is noted that according to other exemplary embodiments, more or fewer than four buffer may be used. According to other exemplary embodiments, more or fewer than five tiers per buffer may be used. According to other exemplary embodiments, more or fewer than 42 logs may be placed on each tier.
Slicing and packaging process 300 receives food product logs from buffering and equilibrating system 110. A sanitizer 302 sanitizes the cased log in preparation for peeling. A peeler 304 removes the clips and casing from the cooked and chilled log. A buffer conveyor 306 provides for an area where any remaining casing may be removed by hand and transports the logs to an autoloader 308. Autoloader 308 loads the logs into a high speed slicer 310. Slicer 310 is configured to slice multiple logs at one time into predefined portions or slices. A check scale 312 then verifies the weight of the sliced portions and those portions out of specification may be rejected. A conveyor 314 moves the sliced portions to a loader 316 that inserts the portions into a seal machine 318 for packaging. Seal machine 318 may, for example, form a film around the portions, vacuumize the formed pockets, flush the pockets with gas, and seal the film, which may be cut into individual packages. A coder 320 then prints information related to a processing and/or expiration date/time onto the packing. A detector 322 scans each package for contamination (e.g., metal) and may reject any suspect packages. A package flipper 324 flips the packages over so the non-forming web of the package is facing down. A tub dispenser/loader 326 places a plastic tub on a conveyor so that the sealed food product can be placed inside of it. A tamper tape applicator 328 places a lid on the tub and seals it with tamper tape. A card stock applicator 330 places a label on top of the sealed lid to identify the contents of the package. A tub code dater 332 places a coded date on the label to identify production date, lot, etc. An automatic case loader 334, packs the plastic tubs that have been lidded, labeled, dated, and sealed into a box. A palletizer 336 then places the packed boxes onto a wood pallet for shipment to another location, for example for sale or use.

A fourth side 410 of food product log 400 extends between second side 406 and third side 408 and has a convex curvature extending away from first side 404. Fourth side 410 generally defines a semi-circular cross-sectional area. First side 404, second side 406, third side 408, and fourth side 410 define a substantially D-shaped cross-section taken perpendicular to the longitudinal axis. According to one exemplary embodiment, the dimensions of first side 404, second side 406, and/or third side 408 relative to the dimension of fourth side 410 may be configured to allow food product log 400 to rest on first side 404, second side 406, or third side 408 without tipping over. According to another exemplary embodiment, second side 406 and third side 408 may provide more than 50 percent of the total height of the D-shaped cross-section and fourth side 410 may provide less than 50 percent of the total height of the D-shaped cross-section. According to another exemplary embodiment, second side 406 and third side 408 may provide less than or equal to 50 percent of the total height of the D-shaped cross-section and fourth side 410 may provide more than or equal to 50 percent of the total height of the D-shaped cross-section.

It is noted that while the use of four food product logs and apertures is illustrated, according to other exemplary embodiments, more or fewer than four food product logs may be sliced and slicing apparatus 114 may define more or fewer than four apertures. According to one exemplary embodiment, each aperture may be spaced apart along a line exiting across the cutting head. According to another exemplary embodiment, the apertures may be spaced in a staggered or uneven alignment that is not across a single line. According to another exemplary embodiment, the fourth side of first food product 500 and the fourth side of fourth food product 506 may be orientated to face in an opposite direction from one another that is generally outward and away from second food product 502 and third food product 504. According to another exemplary embodiment, the first sides of first food product 500 and second food product 502 may be orientated to face an opposite direction towards one another. According to another exemplary embodiment, each food product may be orientated on a like side. According to still other exemplary embodiments, the food products may be orientated in any combination of the orientations described above.
