A deep fat fryer structure includes a floor mounted housing having an upper internal portion in which a side-by-side pair of large capacity metal frypots are operatively supported, each of the frypots having an upper, heated cooking portion from which an unheated cold well depends. Cooking fluid may be drained from the wells for filtration purposes by a valved drainage conduit system having an open outlet end. Filtered cooking fluid may be returned to the upper frypot portions through a valved supply conduit system having a flexible inlet end portion extendable below the frypots. An open-topped, wheel-supported container may be rolled into the housing directly beneath the frypots to receive cooking fluid drained therefrom, and has a cooking fluid filtration element supported on its bottom wall directly over a drain sump depending therefrom. Externally mounted on a front side portion of the container is a motor-driven pump with an inlet communicating with the drain sump, and an outlet provided with a quick-disconnect fitting securable to the flexible inlet end of the supply conduit system. During pump operation, cooking fluid is drained from a selected frypot into the container, filtered therein, and then pumped upwardly into the selected frypot. In this manner, the entire filtration system requires no more floor space than that occupied by the frypot housing, and the container may be rolled outwardly therefrom for cleaning purposes and to provide very convenient access to the motor-driven pump.

Deep fat frying apparatus comprising: a floor supportable housing having a pair of opposite side walls, a front wall, an open lower end, a lower internal portion, an upper internal portion positioned directly above said lower internal portion, and means for defining a horizontally facing access opening through said front wall into said lower internal portion, said access opening extending from the floor to the upper end of said lower internal portion; a pair of frypots each adapted to receive and heat a cooking liquid in which food items may be cooked, said pair of frypots being mounted in a closely adjacent side-by-side relationship within said upper internal portion of said housing, each of said frypots being sized to hold approximately the melted product of a fifty pound block of cooking lard or an equivalent volume of cooking oil and having an upper cooking portion with a narrowed cold well portion depending therefrom, each of said upper cooking portions having a width and an outer side wall positioned closely adjacent one of said side walls of said housing, whereby the side-to-side floor space dimension of said housing is not substantially greater than the sum of the widths of said upper cooling portions of said pair of frypots; drainage conduit means, positioned in said upper internal portion of said housing, for draining cooking liquid from said well portions of said frypots, said drainage conduit means having inlets operatively connected to said well portions to receive cooking liquid therefrom, and an outlet for discharging the received cooking fluid; drainage valve means interposed in said drainage conduit means and operative to selectively initiate and terminate cooking fluid draining from said well portions outwardly through said drainage conduit means; supply conduit means for flowing cooking liquid from a source thereof into said frypots, said supply conduit means having an upper portion disposed within said upper internal portion of said housing and having an outlet communicating with the interiors of said upper cooking portions of said frypots, and an inlet end portion extendable downwardly into said lower internal portion of said housing adjacent said access opening; supply valve means interposed in said supply conduit means and operative to selectively permit or preclude flow of cooking fluid into said frypots through said supply conduit means; and cooking fluid filtration means for receiving cooking fluid discharged from said outlet of said drainage conduit means, filtering the discharged cooking fluid, and returning the filtered cooking fluid to said frypots through said supply conduit means, said cooking fluid filtration means including: a wheel-supported cooking fluid receiving container having a top opening, a bottom wall from which a drain sump depends, a front side portion, and a rear side portion, said cooking fluid receiving container being sized to receive and hold the entire cooking fluid content of either of said pair of frypots, a cooking fluid filter element operatively carried by said cooking fluid receiving container, a pump and associated drive motor carried by said cooking fluid receiving container for movement therewith, said pump having an inlet communicating with the interior of said drain sump, and an outlet, and cooperating quick-disconnect means on said pump outlet and said inlet end portion of said supply conduit means for removably connecting said pump outlet to said inlet end portion of said supply conduit means, said cooking fluid receiving container being rearwardly rollable through said access opening into said lower internal portion of said housing to position said container directly beneath said cold well portions of said frypots, position said open top of said container beneath said outlet of said drainage conduit means, and position said pump outlet adjacent said inlet end portion of said supply conduit means for connection thereto, said container being forwardly rollable outwardly through said access opening for periodic cleaning purposes, whereby said cooking fluid filtration means may be operatively associated with the balance of said deep fat frying apparatus without requiring additional floor space beyond that occupied by said housing, and said pump and its associated drive motor, with said container moved outwardly from said housing means, are readily accessible for maintenance, repair and replacement purposes.
