Patent number: 5044263Abstract: An electrically heatable toaster includes at least one bread holder which is held in toasting position by an electromagnet. The electromagnet has a tripping device which is actuated manually as well as electrically by a timing control. The timing control includes a clock pulse actuated counting circuit connected to a frequency-determining charging capacitor and a voltage divider. The voltage divider includes a temperature-dependent resistor for compensating the influence of the toasting degree temperature and for triggering the electromagnet tripping device after a preset degree of toasting is reached. An oscillator with two complementary transistors combined in a programmable unijunction transistor circuit operates the counting circuit. The transistors are connected on the input side to a charging current circuit of the frequency determining capacitor and on the output side through a dividing point of the voltage divider with the temperature-dependent resistance to a clock input of the counting circuit.Type: GrantFiled: November 3, 1989Date of Patent: September 3, 1991Assignee: Rowenta-Werke GmbHInventors: Karl Birkert, Heinz Marburger, Gunter R.

Patent number: 5044262Abstract: A cooking device and method for selectively automatically cooking and rotating a plurality of food products is disclosed. Cooking information for several cook cycles can be stored and later used to cook selected food products automatically based on the stored cooking information. According to one embodiment, at least sear, cook and hold modes may be programmed to automatically sear, cook and a hold a food product in a rotisserie cooking device. According to another aspect of the invention, automatic fan control during a hold mode is used to selectively operate a fan in a continuous or pulsed mode to minimize product dry out and increase the amount of time a product can be held without lowering the quality of the cooked food product. Another aspect of the invention is related to determining the feasibility of reinitiating an interrupted cooking cycle based on a temperature comparison.Type: GrantFiled: May 15, 1990Date of Patent: September 3, 1991Assignee: Henny Penny CorporationInventors: Douglas A. Burkett, Gary L. Mercer, Robert W. Stirling, David B. Winter

Patent number: 5018438Abstract: An apparatus for preparing foods for predeterminable period of time. One embodiment of the apparatus is for cooking; another is for refrigeration. The apparatus includes either a cooking container or a refrigeration container, a conveyor for carrying food products to and from this container, and a robot assembly for removing food products from the conveyor, inserting them into the container, extracting them from the container after the predetermined cooking or refrigeration period, and returning them to the conveyor. The robot assembly is programmable to extract and return these food products after cooking or refrigeration for a predeterminable period of time.Type: GrantFiled: January 3, 1989Date of Patent: May 28, 1991Inventor: Rene Grandi

Patent number: 5000083Abstract: A salamander-type overhead broiler/cooler has a base on a support adapted to hold a foodstuff to be heated, a heating unit vertically displaceable on the support energizable to radiate heat downward at the support, and a horizontal light curtain at a predetermined spacing fixed relative to and below the heating unit so that the light curtain can be broken by a foodstuff on the base when the unit is lowered. A motor is connected between the unit and the support for vertically displacing the unit and the light curtain on the support and a controller connected between the light curtain and the motor means arrests downward displacement of the unit when the light curtain is broken by a foodstuff on the base.Type: GrantFiled: August 13, 1990Date of Patent: March 19, 1991Assignee: MKN Maschinenfabrik Kurt Neubauer GmbH & Co.Inventor: Hermann Pickave

Patent number: 4821631Abstract: A food cooking device for cooking Oriental dishes is disclosed comprising a base and a cooking pan support means pivoted to the base. An acceleration and deceleration means is provided for rapidly accelerating upwardly from a starting position to at least the rear portion of the support means at an initial high velocity followed by a subsequent rapid deceleration, whereby when the cooking pan is positioned on the support means, it will move upwardly with the support means and propel food placed therein into the air upon rapid deceleration of the support means, thereby causing the food to be turned for uniform heating of different portions of the food.Type: GrantFiled: April 20, 1988Date of Patent: April 18, 1989Inventors: Henry Wong, Pen Weichou

Patent number: 4755656Abstract: An electrical toaster is provided with timer means which is initiated when a food product carrier is secured in an operative position adjacent a toasting element. The timer means normally releases the carrier from its operative position after a toasting interval. In the event of a malfunction, the timer means operates a cut-out to interrupt the supply of power to the toasting element within a predetermined period to prevent combustion or ignition of the food product. The latter period is longer than the normal toasting interval. The timer means may include first and second timing devices for respectively timing the toasting interval and the predetermined cut-out period. Alternatively the timer means provides respective outputs for controlling the toasting interval and the cut-out period.Type: GrantFiled: March 5, 1987Date of Patent: July 5, 1988Assignee: Morphy Richards LimitedInventors: Eric Charlesworth, Stephen D.
