Abstract: Systems and methods are disclosed that include providing a cooking system that comprises a burner assembly and a heat exchanger, the burner assembly having a high velocity burner configured to provide the necessary high velocity, volumetric flowrate through the heat exchanger having a first fluid circuit having a plurality of compactly-arranged tubes disposed perpendicularly and interstitially to a second fluid circuit having a plurality of compactly-arranged tubes, and the burner assembly also having a low velocity burner configured to significantly reduce and/or substantially eliminate “lift off” that could result from operation of only the high velocity burner.

Abstract: An oven has a first conveyor, a first burner that directs heat toward the first conveyor from above the first conveyor, and a second burner directs heat toward the first conveyor from below the first conveyor. A method includes providing foodstuff on a conveyor, exposing the foodstuff to heat directed toward the foodstuff from above the conveyor, and exposing the foodstuff to heat directed toward the foodstuff from below the conveyor. Another oven has a first conveyor and first conveyor insulators that surround the first conveyor and define a first zone. Another method includes introducing foodstuff to a first conveyor belt within a first insulated zone, introducing heat into the first insulated zone, and retaining a portion of the heat within the first insulated zone. Another oven has an insulated cooking zone that closely envelopes a cooking path and an insulated oven zone that substantially envelopes the cooking zone.

Abstract: A product removal method that includes providing a blade adjacent a conveyor belt along a path of the conveyor belt and operating the conveyor belt. A product removal system that has a rod oriented generally parallel to a conveyor drum is disclosed. A frame is rotatably carried by the rod and has a first portion extending adjacent a conveyor belt curved path and a second portion extending adjacent a return plane of the conveyor belt. A blade is adjacent the first portion. A product removal system for an oven is disclosed that has scraper assemblies rotationally biased about an axis of rotation.
