PRODUCTION FLOW-RATE MEASUREMENT OPTIONS FOR FOOD PROCESS LINES

Abstract

A transfer conveyor for food process lines has an endless conveyor belt characterized by an upper, food-product carrying run and a lower, return run. The upper, food-product carrying run defines a transit plane. The upper, food-product carrying run also extends between an intake end and a discharge end. The upper, food-product carrying run furthermore has a first pleat below the transit plane proximate the intake end and a second spaced-away pleat below the transit plane proximate the discharge end. These spaced-away pleats partitioning the upper, food-product carrying run into an intake-end span and a discharge-end span cooperatively flanking a mid-span. Wherein the transfer conveyor additionally includes one scale servicing the intake-end span of the upper, food-product carrying run and another scale servicing the discharge-end span.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0051] FIGS. 1 through 4 show a first embodiment of mechanized food-process line equipment arranged in a working food process line 100 and furnished with production flow-rate measurement options 150 in accordance with the invention. FIG. 5 is comparable to FIG. 4 except showing an alternate embodiment of a production flow-rate measurement option 150 in accordance with the invention.

[0052] To turn to FIG. 9, it shows in block diagram format a series of food process line machines 107-113 configured in a non-limiting example of a working food process line 100.

[0053] In series, from right to left, the machines in FIG. 9 comprise: [0054] a food-product 104 load station 107; [0055] a food-product 104 spreading station 108; [0056] a weighing transfer conveyor 150; [0057] a pre-dust coating 102 coating machine 109; [0058] a weighing transfer conveyor 150; [0059] a batter 103 batter-coating station 110; [0060] a weighing transfer conveyor 150; [0061] a seasoning 102 applying/coating machine 111; [0062] a weighing transfer conveyor 150; [0063] a batter 103 batter-coating station 110; [0064] a weighing transfer conveyor 150; [0065] a Panko-crumb 102 coating machine 142; [0066] a weighing transfer conveyor 150; [0067] a fryer 112 providing a bath of hot oil 101;
and so on. The fryer 112 might be set/limited to fry for a twenty-thirty second dwell time, which corresponds to a par-fry.

[0068] FIGS. 6-9 provide several non-limiting examples of food process line 100 configurations in accordance with the invention and show a like the series of stations/machines as outlined above.

[0069] It is an object of the invention to provide the supervisory attendant (superintendent) with weight-flow (˜ mass-flow) of product across any weighing transfer conveyor 150 in accordance with the invention for real-time feedback of weight-flow values.

[0070] FIG. 4 shows a weighing transfer conveyor 150 in accordance with the invention. The weighing transfer conveyor 150 has scales 152 and 156 at both the intake end 154 (eg., to the right in the view) and outflow end 158 (to the left in the view). For example, the intake scale 152 might indicate that past one or another coating machine 109-113, there was a 5% pick-up of coating material 101-103. However, the outflow scale 156 might indicate that some coating material 101-103 shook off across the transit of the weighing transfer conveyor 150, showing that there was only a 4.8% pick-up of coating material remaining. This issue is not just limited to dry coating material 102, albeit it is more typical with dry coating material 102.

[0071] Preferably, several such weighing transfer conveyors 150 are used to space the various process machines 107-113 apart.

[0072] FIG. 5 is a side view comparable to FIG. 4 except showing an option with flip or agitation sections 160 so this could possibly remove some coating material (eg., 102) and then, when the proper weight pick-up is reached as specified in the production instruction, the food product 102, 104 conveyance is returned to a flat transit mode.

[0073] Hence the weighing conveyor 150 not only provides weight-flowrate measurements at both the intake and outflow nose end 154 and 158, the weighing conveyor 150 might be equipped with various provisions 160-163 to increase or decrease the pick-up percent.

[0074] The following techniques can be employed to adjust the pick-up percent. For dry particulate coatings 102, techniques which would increase pick-up percent include: [0075] add more breading material 102 into the coating machine (eg., 111); [0076] add finer breading material 102 into the coating machine (eg., 111); [0077] use a compression roller 161 at the outflow; [0078] increase the pressure of the compression roller 161; [0079] turn down the flowrate of air knives 162 at the outflow; [0080] add moisture 163′ to the food product 104 at the inflow; [0081] reduce/eliminate shaking/thumping/agitation 160 of the outflow; and so on.
For dry particulate coatings 102, techniques which would decrease pick-up percent include: [0082] eliminate addition of moisture 163′ to the food product 104 at the inflow; [0083] decrease the pressure of the compression roller 161; [0084] increase shaking/thumping/agitation 160 of the outflow to knock-off excess; [0085] increase the blast from the air knifes 162 to blow-off excess; and so on.
For batter, a further technique for adjusting increase or decrease of pick-up percent includes thickening or thinning the batter 103. The batter 103 is readily made thicker by adding more powder. In the other direction, the batter 103 is readily made thinner by adding more water.

[0086] FIG. 11 shows an exemplary series of processes and operations that move batch-stored food product in the vats 120 shown in FIG. 10 onto a loading zone 107 and/or 108 of a food process line 100. Ice 106 is preferably scooped/shoveled off the surface of the slurry 104-106 in the vats 120. The meltwater 105 is left behind with the chicken tenders 104. The vat 120 is poured/emptied likely into a holding tank 132 of some sorts at the start. The contents of the holding tank 132 are pumped (by a pump 124) into a marinade tumbler 126. The meltwater 105 is put to good use to dissolve the powdered marinade 128. The outflow of the marinade tumbler 126 is pumped/poured onto a landing conveyor 107 and/or 108 of some sort. The landing conveyor 107 and/or 108 will be of an open construction 172 like a chain link belt, or drag link belt and so on. The excess water 105 at this point is allowed to flow through the belt 172 and into an underlying drain 174. Food product 104 has hence landed onto the initial inflow end of the food process line 100.

[0087] FIG. 12 shows one version of what can functionally transpire in detail XII/XIII-XII/XIII in FIG. 11. A food product loader 107 in accordance with the prior art is loading food product (which food product is not visible in the view) onto a landing conveyor 107 and/or 108 also in accordance the prior art. The landing conveyor 107 and/or 108 affords a longitudinal run of conveyor transit which allows some implementation of some form of product spreading technology. This can be manual. Typically two to three workers would stand on each side of the conveyor 107 and/or 108 and move product 104 apart so that single pieces are not touching each other. There are other options to accomplish this which are not manual.

[0088] Here in FIG. 12, the landing conveyor 107 and/or 108 discharges to a weighing transfer conveyor 150 in accordance with the invention, and the weight-flowrate measured here is the inflow flowrate of raw chicken tenders 104. The flowrate can be adjusted practically immediately at start-up to the max flowrate of the ‘bottleneck’ of the food process line 100. This was mentioned above to be nearly always the maximum throughput flowrate through the fryer 112.

[0089] FIG. 13 shows an alternate option to FIG. 12. FIG. 13 is a side elevational view comparable to FIG. 4 and providing an alternate functional representation of detail XII/XIII-XII/XIII in FIG. 11.

[0090] Here in FIG. 13, the loading of raw food product is poured/pumped directly onto a weighing transfer conveyor 150 in accordance with the invention. Wherein the weighing transfer conveyor 150 likewise has a mid-span which affords implementation of some form of product spreading technology, whether it be manual or otherwise.

[0091] For weighing conveyors 150 situated before or after coating apparatus 109-113, the mid-span can accommodate the mounting of some technology like thumpers/shakers/agitators 160 for knocking off excess coating material (eg., 102), or air knives 162 for blowing off excess coating material (eg., 102), or else compression rollers 161 for driving in the particulate to increase retention, misters 163 to moisten the product 104 and so on.

[0092] FIGS. 14 and 15 are schematic side elevation views of a further embodiment of a weighing transfer conveyor 180 in accordance with the invention. FIG. 14 shows this weighing transfer conveyor 180 in an expanded position. FIG. 15 shows this weighing transfer conveyor 180 in a contracted position.

[0093] FIG. 16 shows that this further embodiment of a weighing transfer conveyor 180 allows pivoting about a vertical axis in addition to being reversibly expanding-contracting.

[0094] FIG. 17 is a top plan view, partly in section, taken in the direction of arrows XVII-XVII in FIG. 16, showing aspect of the pivot hardware 182 and turntable 184.

[0095] FIG. 18 is a perspective view comparable to FIG. 16 except showing the transfer conveyor 180 situated between two machines which do not pivot (any of 107-113) and showing the transfer conveyor 180 pivoted obliquely away from the main axis 190 of the food process line 100.

[0096] The role for pivoting is not during production run time, but during down time. The advantages of pivoting enable cleaning and/or maintenance operations without breaking apart the food process line 100 as a whole.

[0097] The invention having been disclosed in connection with the foregoing variations and examples, additional variations will now be apparent to persons skilled in the art. The invention is not intended to be limited to the variations specifically mentioned, and accordingly reference should be made to the appended claims rather than the foregoing discussion of preferred examples, to assess the scope of the invention in which exclusive rights are claimed.
