ABSTRACT:
An apparatus and method for determining a load size of a food product in a cooking device is described. The apparatus includes a carrier assembly for receiving a food product; a cooking vessel containing a cooking medium, for receiving the carrier assembly; a lid assembly for raising and lowering the carrier assembly; a weight-bearing portion for supporting the lid assembly and the carrier assembly; a load sensor placed on the weight-bearing portion so as to measure a weight of the carrier assembly, the load sensor providing an output signal; and a control device for receiving the output signal and determining cooking parameters for the food product. A method for determining a load size of a food product in a cooking device includes the following steps: weighing a carrier assembly when the carrier assembly is empty to determine an empty carrier weight; weighing the carrier assembly when the carrier assembly contains a food product to determine a loaded carrier weight; determining a differential between the empty carrier weight and the loaded carrier weight, resulting in a food product load; reporting the food product load; and modifying cooking parameters responsive to the food product load.
