Patent number: 7424848Abstract: A cooking device that is capable of rapidly cooking food products such as in toasting bread products or cooking pizza. The cooking device uses air impingement from above and/or below the food product. In some cases an infrared heater is additionally used to impart a desired color and crunchiness about a surface of the food product. In some cases, a boost in thermal energy is applied to the bottom of the food product vis-à-vis the top thereof. In some cases, the boost is due to an extra heater, which may be gas or electric. The device is particularly adapted for toasting bread products, cooking sandwich products (toasting the bread and heating the sandwich filler) and/or cooking pizza. Rapid cooking times are achieved by delivering more thermal energy to the top or bottom of the food product, depending on the type thereof, to give quality and speed. For example, a pizza can be cooked to have a crisp bottom without burning a cheese topping.Type: GrantFiled: November 4, 2004Date of Patent: September 16, 2008Assignee: Lincoln Foodservice Products, Inc.Inventors: Douglas S.

Publication number: 20080184898Abstract: A conveyorized return toaster for toasting food products has an inclined angled conveyor for conveying the food products from a lower point outside the toaster to a higher point in the toaster. The inclined angle is at a degree sufficient to cause the center of gravity of the food product to shift rearward from where it would be on a horizontal conveyor and allow the product to extend at a length further beyond the back end of the inclined conveyor than if the conveyor were horizontally disposed. This increases the rotational moment of the food product over the back end of the conveyor and increases the subsequent food product exit force to propel the food product completely to the front opening of the toaster.Type: ApplicationFiled: December 7, 2007Publication date: August 7, 2008Inventors: Ming Lung Huang, Vincent Anthony Maranto

Patent number: 6655263Abstract: To reduce running costs and equipment costs by bringing entire surfaces of noodle strings carried on a conveyor into contact with steam. High-temperature steam is upwardly supplied from a steam pipes (30) installed on a lower cover (24), by running a delivery belt lane (36a) of a belt conveyor (28)through a steam chamber (26). The belt conveyor (28) is equipped with an endless belt (36), whose delivery lane (36a) passes through the steam chamber (26). The belt (36) is a thin, mesh belt positioned so as to partition the steam chamber (26) into an upper steam chamber (26a) and a lower steam chamber (26b).Type: GrantFiled: December 30, 2002Date of Patent: December 2, 2003Assignee: Fuji Manufacturing Corporation Ltd.Inventor: Hatsuo Sakurazawa

Publication number: 20030217645Abstract: A conveyor oven having a heating chamber and an oven chamber. A conveyor is disposed in the oven chamber to convey food products between an entry port and an exit port. An air impingement assembly is disposed to provide jets of impingement air toward the food product. A fan blower, a heater and a moisture delivery device are arranged to provide heat and moisture to an airflow to the air impingement assembly so that the jets of air are heated and laden with moisture and provide as a blanket-like mixture of air and moisture at the surface of the food product..Type: ApplicationFiled: March 27, 2003Publication date: November 27, 2003Applicant: Enodis CorporationInventors: Douglas S. Jones, Paul R. Molloy, William J. Day

Patent number: 6638553Abstract: The system and method for monolayer alignment snack chip transfer process a snack chip from a first to a second conveyor. By using a roll at the discharge of the toast oven conveyor that has a diameter that is substantially closer in size to the pickup roll of the second conveyor, mechanical devices for lifting the chips off of the toast oven conveyor can be avoided. Further, chip preforms' alignment in passing between the two conveyors is maintained.Type: GrantFiled: October 9, 2001Date of Patent: October 28, 2003Assignee: RECOT, Inc.Inventors: Brian Keith Bell, Steven Theodore Chandler, Eric P. Farabaugh, Joseph H. Gold, Terry Dale Klockenga, John Curtis McConn, Daniel Eugene Orr, Edward Leon Ouellette, Scott L. Robinson, Heinz Roel, Richard James Ruegg

Publication number: 20030196558Abstract: An automated grill automatically transfers frozen food from a freezer component to grilling component by an automatic loading device in response to a signal. Frozen food is loaded in a loading side in the freezer component. When the signal is received indicating that the food is to be grilled, food in a feeding side is raised and delivered to the loading device. When a sensor detects that food is positioned in the loading device, the loading device removes the food from the freezer component and into the grilling component. The food is then grilled as it travels between two substantially vertical grilling structures each surrounded by a conveyor belt. Preferably, the conveyor belt is made of a non-stick coated Invar. A lateral sensor detects and compensates for lateral movement of the conveyor belts. After the food exits the grilling component, the food slides onto a heated holding area for serving.Type: ApplicationFiled: April 17, 2002Publication date: October 23, 2003Inventors: Jeffrey L. Sands, James D. Conlin, Thomas J. Franken, Andrew Paul Franklin, Randy L. Ginner, Ronald J. Glavan, Scott A. Glawe, David A. Hill, Michael J.

Publication number: 20030196560Abstract: A grilling component employed to grill food items includes a grilling surface made of a material having a low constant of thermal expansion. In one example, the grilling surface is made of Invar™. Invar™ is a metal allow comprised of Iron and 36% Nickel, and may include other trace elements. Invar has a low constant of thermal expansion and therefore moves and expands very little when heated. The grilling surface further includes a non-stick coating, such as Teflon™. The grilling surface can also be a conveyor belt which travels over a heater.Type: ApplicationFiled: April 17, 2002Publication date: October 23, 2003Inventors: Jeffrey L. Sands, Ronald J. Glavan

Patent number: 6629493Abstract: Apparatus for preparing parbaked food products, such as pizza crust shells, and dough formulation used therein, and the product produced thereby and/or therefrom. The apparatus operates on a starting material dough including flour, sugar and water, and preferably also a leavening agent such as instant yeast. The dough is rounded, first proofed, panned, pressed and second proofed in the apparatus. The prepared dough piece is then steam hydrated in the apparatus under conditions sufficient to cause moisture absorption and a resultant increase in moisture content throughout the dough. Then the hydrated dough piece is immediately sequentially parbaked until gelatinization of the starch is complete.Type: GrantFiled: January 9, 2002Date of Patent: October 7, 2003Assignee: M & M Holdings, Inc.Inventors: John E. Schaible, II, Jeffrey R. Pakulski

Patent number: 6595119Abstract: A Rotisserie Oven includes a heat source and a continuous conveyor mounted adjacent to the heat source. A number of skewer holding devices are affixed along the conveyor and each hold a skewer adjacent the heat source while being convey past the heat source. Turning devices are provided for rotating the skewers as they pass the heat source. A skewer detachment mechanism is provided to enable detachment of the skewer from the conveyor at an end of the rotisserie oven.Type: GrantFiled: June 13, 2002Date of Patent: July 22, 2003Inventor: Chun Kong Ian Cheung

Patent number: 6595117Abstract: A cooking appliance which is capable of rapidly toasting a food product disposed therein by air impingement and infrared heating to provide a cooked food product having the desired color and crunchiness about its surface. The appliance is particularly adapted for cooking sandwich products, toasting the bread and heating the sandwich filler. The appliance includes an air impingement assembly that delivers columns of heated air to the food product and an infrared heater assembly that produces infrared energy. The appliance delivers the impingement air from above the food product and the infrared energy from below. Alternatively, the appliance delivers the impingement air from above and below the food product and the infrared energy from below.Type: GrantFiled: August 4, 2000Date of Patent: July 22, 2003Assignee: The Frymaster CorporationInventors: Douglas Jones, William Day, David Harter, Gerald W.
