Claim:
1. An improvement for food process-line coating apparatus for coating a stream of food product and having provisions for the exchangeable substitution or elimination of accessories of the tumbling and/or flipping nature; having: an intake conveyor having an upper food-product carrying run and a lower return run, and extending between an intake end for intake of a food product stream from upline processes in said food process-line and a discharge end for discharge of the food product stream to a direct destination within said coating apparatus; an overhead coating material dispenser for dispensing coating material on underpassing food product on the food-product carrying run of the intake conveyor; and an outflow conveyor having an upper food-product carrying run and a lower return run, and extending between a receiving end for receipt of a food product stream from a source within said coating apparatus and a discharge end for discharge of the food product stream to a downline process in said food-process line; wherein said coating apparatus is alternately configurable among a first configuration and a second configuration; and each of the first and second configuration comprise plural variations; I.a. wherein one variation of said first configuration has said coating apparatus further comprising a rotary drum for tumbling coated food product; said drum extending between an intake end and a discharge end and is mounted with respect to the intake conveyor and outflow conveyor such that said drum's intake end serves as the direct destination within said coating apparatus for the discharge end of the intake conveyor, and, such that said drum's discharge end serves as the source within said coating apparatus for discharging tumbled coated food product on the receiving end of the outflow conveyor; I.b. wherein another variation of said first configuration has said coating apparatus further comprising—in substitution of the rotary drum—conveyor-type tumbling apparatus for tumbling coated food product; said conveyor-type tumbling apparatus having a endless conveyor belt defining a food-product carrying run as well as a return run therefor wherein the endless conveyor belt is driven such that the direction of advance for the food-product carrying run is generally transverse to an upline-to-downline direction of the food product line, and wherein the endless conveyor belt has a leading lateral edge which in the food-product carrying run defines an intake end as well as has a trailing lateral edge which in the food-product carrying run defines a discharge end; said food-product carrying run being horizontally supported to sag and define a generally horizontal trough whereby food product tumbles in the trough as the food product transits downline from the intake end to the discharge end; said drum being mounted with respect to the intake conveyor and outflow conveyor such that said endless conveyor belt's intake end serves as the direct destination within said coating apparatus for the discharge end of the intake conveyor, and, such that said endless conveyor belt's discharge end serves as the source within said coating apparatus for discharging tumbled coated food product on the receiving end of the outflow conveyor; II.a. wherein one variation of said second configuration has said coating apparatus further comprising—in substitution of the rotary drum and in substitution as well of the conveyor-type tumbling apparatus—zero or more intermediate inline conveyors for level bypass conveyance of coated food be passed to the outflow conveyor without being tumbled, whereby delicate food product like burger patties or fish patties can be passed on to the outflow conveyor; II.b. wherein another variation of said second configuration has said coating apparatus still comprising—in substitution of the rotary drum and in substitution as well of the conveyor-type tumbling apparatus—said zero or more intermediate inline conveyors; said zero or more inline conveyors as well as the outflow conveyor being inclined at a shallow tilt such that food product is afforded the opportunity to flip at each progressive transfer to the first of the zero or more inline conveyors and/or outflow conveyor, successively to the transfer to the outflow conveyor, such food product is afforded at least one opportunity to flip between the intake conveyor and the outflow conveyor; said improvement comprising: a third configuration of said coating apparatus comprising—in substitution of not only the rotary drum as well as the conveyor-type tumbling apparatus but also in substitution at least one of the zero or more intermediate conveyors—an accessory of the tumbling and/or flipping nature distinct from the first and second configurations.
