摘要： Cooking apparatus controlled by a programmed digital microcomputer for determining whether the cooking process is complete and for filtering the cooking medium when, for example, only one cooking process is complete. The apparatus also determines whether the cooking medium has been filtered and locks out the initiation of a cooking process after, for example, the completion of only one cooking process at least until the apparatus determines that the cooking medium has been filtered.

摘要： A method and apparatus for controlling the speed at which an AC electric motor drives a conveyor to move food products through a conveyor oven are disclosed herein. The oven includes a housing, electric heating elements mounted within the housing, and a conveyor to move food-carrying baskets adjacent the heating elements. A motor controlled by a speed control circuit moves the conveyor. The speed control circuit includes a rectifier to provide rectified current to the motor, a shunt circuit to bypass the rectifier with a rheostat to set the conveyor speed, a thermostat to monitor oven temperature, and a speed-reducing circuit to introduce additional resistance into the shunt circuit when the oven temperature drops. The thermostat also controls additional heating elements to provide additional heat during high load conditions. If an increase in oven load causes a drop in temperature, the additional heating elements are turned on and the conveyor speed is reduced as the additional resistance is introduced into the shunt circuit. The slower speed gives additional heating time at low oven temperatures. The method and apparatus disclosed herein may also be used with conveyor ovens for non-food products.

摘要： Computer controlled cooking apparatus for extending the life of shortening utilizing a host computer to lower the average temperature to which the shortening is subjected, a cooking computer within each cooking apparatus to determine when a filter operation should occur based upon how many of each of a plurality of foods have previously been cooked, a technique for locking out future cook cycles until a filter operation has occurred so that the quality of the shortening is maintained, and a technique to prevent shortening from burning by ensuring that the solidified shortening is gradually melted before it is subjected to the much higher power. Additionally, a cooking profile for each food is utilized in order to determine if food being cooked during a power failure may continue to be cooked when the power is restored or if such food may be discarded.

摘要： An oven cooking monitor and method automatically control the cooking, to a selected degree of doneness, of a plurality of food times requiring different cooking times, thereby permitting the food items to be loaded into the oven in random size order and to be removed in the order in which they become done. In restaurant or fast food cooking a number of different roasts of beef of different sizes often are placed in an oven to be cooked to a uniform degree of doneness, or roasts of similar or different size are placed in an oven at different times. Uniform cooking, without overcooking, is achieved through the present invention by providing a separate disconnectable probe for each food item to generate a signal varying with the temperature sensed by each probe. A reference temperature signal is set to correspond to a desired degree of doneness, and the sensed temperature signal and reference temperature signal are compared, yielding an output signal when the sensed and reference temperatures match. When an output signal is generated to indicate that one of the food items has reached the desired degree of doneness, the monitor indicates the particular probe associated with the done food item and automatically switches the oven to a holding temperature substantially curtailing further cooking. The done food item is removed, and its probe is disconnected, whereupon the monitor stops the probe indicator and automatically switches the oven again to its cooking temperature. Cooking then proceeds until the next food item is done. In this fashion, a plurality of food items such as roasts can be cooked without requiring careful supervision, and without exceeding a prescribed degree of doneness, thereby reducing waste. Roasts may be loaded randomly, and removed in the indicated order in which they become done.
摘要翻译：烤箱烹饪监视器和方法可以自动控制需要不同烹饪时间的多个食物时间的烹饪，选择的程度，从而允许食物以随机大小的顺序装载到烤箱中，并在他们完成的顺序。在餐厅或快餐店中，将不同大小的不同大小的不同牛肉的烤肉经常放置在烤箱中以均匀的煮熟程度，或者在不同时间将烘烤的相似或不同的大小放在烘箱中。通过本发明，通过为每个食品提供单独的可断开的探针以产生随着每个探针感测到的温度而变化的信号，从而实现均匀的烹饪，而不需要超煮。参考温度信号被设置为对应于期望的程度，并且所感测的温度信号和参考温度信号被比较，当感测和参考温度匹配时产生输出信号。当生成输出信号以指示其中一个食物已经达到所需的程度时，监视器指示与完成的食品相关联的特定探针，并且自动将烘箱切换到基本上抑制进一步烹饪的保持温度。完成的食品被移除，其探头断开，监视器停止探头指示器，并自动将烤箱再次切换到其烹饪温度。然后进行烹饪，直到下一个食品完成。以这种方式，可以在不需要仔细监督的情况下烹饪诸如焙烤的多个食物，并且不超过规定的昼夜程度，从而减少浪费。烤肉可以随机装载，并以指定的顺序进行去除。

摘要： An oven device for final finishing of a food item includes an oven housing defining a heating cavity, and an upper heating unit disposed within the oven housing above the heating cavity. The heating cavity is configured to receive at least one food item to be heated by the oven device. The upper heating unit includes an upper heating element. The upper heating unit generates radiant heat which is directed onto the at least one food item when the at least one food item is received in the heating cavity. The upper heating element includes a rapidly-heating, high-intensity heating element capable of being cycled on for final finishing of the at least one food item when the at least one food item is received in the heating cavity, and capable of being cycled off when such final finishing is not being performed. The final finishing typically includes browning a top surface of the food item, or melting a topping onto the top surface of the food item.
