Patent number: 5931081Abstract: The present invention features an electrical, frying appliance that uniformly cooks food items placed within its food basket. This frying appliance automatically immerses and extracts the cooking basket into and out of an aluminum oil bowl containing heated oil. In this fashion, the food in the basket is uniformly fried during the cooking cycle. The frying appliance contains a translationally movable basket that operates by a transmission wire driven by a shaft. The translational movement of the food basket allows the food in it to lie flat as it is immersed in the aluminum oil bowl. The food basket remains substantially horizontal during its movement between its immersed and non-immersed positions. In this fashion, the food items are prevented from shifting around in the frying basket. This allows the food to fry evenly within the basket and, when cycled, to be drained of oil periodically.Type: GrantFiled: May 29, 1998Date of Patent: August 3, 1999Assignee: Wing Shing Products (BVI) Co. Ltd.Inventors: John C. K. Sham, Kumkit KunavongVorakul

Patent number: 5827556Abstract: A controller for controlling the cooking of food within a cooking apparatus. The controller is comprised of a temperature sensor input for receiving an output of a temperature sensor and a system for initiating a cook of a food product based upon a set cook temperature and a set cook time. Plural indications of incremental energy that is absorbed by the food product during the cook are determined, wherein each of the plural indications of incremental energy is based upon a difference between a temperature determined at the temperature sensor input and a desired internal temperature of the food product. The end of the cook is established when the total of the plural indications of incremental energy is one of equal to and greater than an ideal energy to prepare the food product based upon the set cook time and the cook temperature.Type: GrantFiled: October 23, 1996Date of Patent: October 27, 1998Assignee: Tridelta Industries, Inc.Inventor: Charles A.

Patent number: 5771781Abstract: The present invention features an electrical, frying appliance that uniformly cooks food items placed within its frying basket. This frying appliance cyclically immerses and extracts the cooking basket into and out of a pan containing heated oil. In this fashion, the food in the basket is uniformly fried during the cooking cycle. The frying appliance contains a translationally moveable basket that operates by a parallel linkage driven by a gear train and worm drive mechanism. The translational movement of the basket allows the food in it to lie flat as it is immersed in the oil. The frying basket remains substantially horizontal during its movement between its immersed and non-immersed positions. In this fashion, the food items are prevented from shifting around in the frying basket. This allows the food to fry evenly within the basket and, when cycled, to be drained of oil periodically.Type: GrantFiled: July 28, 1997Date of Patent: June 30, 1998Assignee: Pentalpha Enterprises Ltd.Inventor: John C.
