  • Griddle control for minimum temperature variation
    Patent number: 4502461
    Abstract: A temperature control means for a cooking griddle wherein a tubular thermostat is clamped to the bottom of the griddle plate, shielded from direct engagement by the heating medium and having a predetermined portion of the temperature sensing bulb of the thermostat directly exposed to the heating medium for cooperation with the actuating fluid in the thermostat tube so as to operate the on-off switch of the heating medium within a temperature range of about 5 degrees F.

  • Cleaning system for deep fryer
    Patent number: 4502373
    Abstract: A common filter for one or more deep fat fryers includes a nozzle in the bottom of each fryer vessel for delivering filtered fat in a non-aerated whirlpool-like flow for flushing dislodged food particles through a drain to a portable filter tank. A pump delivers filtered fat from the filter tank to the nozzle for cleaning and refilling of the vessel.
