Abstract: There is provided a system and a method for assessing a quality of a cooking medium in a fryer. The system includes a fryer pot, a filtration unit, a conduit, an electronic module, and a processor. The conduit is in fluid communication with the fryer pot for carrying the cooking medium from the fryer pot through the filtration unit back to the fryer pot. The electronic module collects values of a plurality of operating parameters of the fryer, over a period of time. The processor produces an assessment of the quality from an evaluation of the values in accordance with a model of a relationship between the quality and a combination of the operating parameters. There is also provided a storage device that contains instructions for controlling the processor.

Abstract: A method that includes: (i) detecting an acoustic wave that is propagating through a body of water, as the body of water is being frozen on a structure, thus yielding a detected acoustic wave; (ii) extracting, from the detected acoustic wave, (a) a frequency component thereof, and (b) a magnitude of the frequency component; and (iii) removing the body of water from the structure when the magnitude exceeds a threshold value.

Abstract: A controller continues to operate an ice making machine in a safe mode when a failure of a component is detected. While in the safe mode due to failure of an ice thickness probe, the freeze cycle freeze time is based on an average freeze time of a predetermined number of the most previous freeze cycles prior to the failure. While in the safe mode due to failure of a water level probe, the water valve on time is based on an average water valve on time of a predetermined number of the most previous freeze cycles prior to the failure. If the failure is uncured after a predetermined time, the controller causes the ice making machine to enter a standby mode or disables the ice making machine from making ice.
