Abstract: A hot oil fryer for continuous frying duty in continuous food process lines has a conveyor belt that has an upper food-carrying upper run and a lower return run. Heat input is provided by rectangular or square heat exchanger tubes that are placed directly underneath the food-carrying run in order to support it from sagging as well as cut-down the span between the source of heat flowing inside the heat exchanger tubes and the sink of heat in the food product that is transported on top of the conveyor's food-carrying run. The conveyor includes an entrant ramp section having at least high and low operative positions. The cooking channel at the intake end is provided with a series of gutters as well as sediment drains to afford collection and filtration of floating debris as well as sinking debris.
