A method for reducing energy consumption in a steam cooker that includes a steam cooking cavity, a steam generator for delivering steam along a steam path to the steam cooking cavity, a steam outlet from the steam cooking cavity to a first flow path leading to a drain path. The method involves: (a) utilizing a second flow path from the steam outlet to a vent stack to deliver excess steam flows from the steam cooking cavity up the vent stack rather than down to the drain box; (b) sensing temperature within the vent stack; and (c) utilizing sensed temperature within the vent stack to regulate power of a heating unit of the steam generator to produce steam in a controlled manner that reduces flows of excess steam out of the steam cooking cavity.

Steam cooking oven and method

A steam cooking system includes a steam cooking chamber having an access door and a drain for draining condensate from the steam cooking chamber along a drain path. A steam generator unit heats water to generate steam. The steam generator unit is connected for delivery of steam from the steam generator to the steam cooking chamber via a first steam path during a cooking operation. The steam generator unit is also connected for delivery of steam from the steam generator to the drain path via a second steam path during a steam flushing operation.

A stacked steam oven construction with a nested stacking component is described.

Stacked steam oven construction

A steam oven includes a cooking cavity for receiving food product and a water reservoir for receiving water to be heated to generate steam, the water reservoir defined in part by a bottom wall structure of the cooking cavity. A heater plate located adjacent the bottom wall structure delivers heat through the bottom wall structure to water in the water reservoir. A spring-loaded heater plate mount arrangement supports the heater plate adjacent the bottom wall structure while permitting some movement of the heater plate.

A steam cooker includes a steam generator including a heating chamber defining a volume for holding water. A heat exchanger is associated with the heating chamber so as to generate steam. A steam superheater superheats steam traveling from the heating chamber to a steam cooking chamber.

Steam cooker and related superheater

The invention relates to a method and system for producing steam in a heating unit, and a method of designing a heating unit for producing steam. The method relates to receiving a liquid including impurities at a predetermine flow rate within an entry port of a monotube in the heating unit, where the monotube has a lumen of a predetermined size. The received liquid is converted into a two phase flow including turbulent and laminar flow. At least the turbulent flow is passed through the lumen at a velocity sufficient to carry the impurities through an exit port of the monotube and produce steam. The velocity of the turbulent is responsive to at least the predetermined flow rate and predetermined size of the lumen.

Flash steam generator

A steam generator includes a heating chamber for holding water. The heating chamber has a water inlet, a steam outlet, and a water draining outlet. A nozzle is in communication with the water inlet and is positioned to direct incoming water into the water draining outlet. A heating system is associated with the heating chamber for heating water to generate steam and a control system is operable to control filling and draining of the heating chamber.

A steam oven includes a heating chamber or boiler in which steam is generated. Water fill and refill operations of the heating chamber are controlled in attempt to account for water expansion and/or to enable substantially regular production of steam.

Steam oven system having steam generator with controlled fill process

An atmospheric steamer includes a steam chamber defined at least in part by a housing, and a water retaining area having at least one associated heating element for heating the water to generate steam. A vent opening is provided through the housing. A steam diverting baffle may be positioned around the vent opening to define a passage which leads to the vent opening. A sensor may be positioned along a vent path from the vent opening for sensing passage of steam along the vent path.

Atmospheric steamer

A non-contact system and method is provided for effectively approximating the internal temperature of food being cooked upon a cooking surface of a cooking apparatus, such as a grill or griddle. Ultrasound or infrared, non-contact measurement devices may be directly installed onto the cooking apparatus, and in concert with a computerized monitoring/control system, are used to monitor the status of the food being cooked, or to control the heat input to the cooking surface using a feedback loop. The non-contact measurement devices may be permanently positioned above the cooking surface or may be mounted to arms that can be pivoted, or otherwise moved into position over the cooking surface.

Systems and method for non-invasive assessment of cooked status of food during cooking

The present invention provides a combination continuous and batch filtration system for a recirculating fryer where the continuous filter and batch filter assemblies are integrated into a single unit, utilizing a common pump. This unit is substantially compact and is therefore able to fit within the frame of most recirculating fryers. The outlets of the continuous filter and the batch filter are connected to a two-way valve, which is, in turn, connected to the inlet of the common pump. The valve allows an operator to selectively pump cooking fluid from either the continuous filter or the batch filter back into the fryer vat.
