Abstract: A food sealing device for shrink-wrapping foods such as pizza includes a heat source surrounded by an inner shroud to create an updraft for heating the film. A second outer shroud is positioned around the inner shroud to prevent the film from contacting the hot inner shroud to prevent melting of the film against the inner shroud which might otherwise damage the film or the food item.
Abstract: A control circuit is disclosed suitable for use with a toaster or other food browning device which utilizes a radiant energy source to brown food. A light sensitive variable resistor, or photocell, is optically coupled to light reflected from the food being browned in the device. A voltage generated by a voltage divider including the light sensitive resistor therein is compared with a preselectable voltage generated by a second voltage divider to determine whether the heat source should be turned on or off. Suitable solid state control circuitry is provided to ensure that a start-up delay is provided at the beginning of each browning cycle and to reset the circuit for future operation when the desired browning of the food is achieved.
