  • Heat sealer with algorithm for regulating sealing temperature
    Patent number: 9021771
    Abstract: A vacuum and sealing appliance comprises a heat sealing element for sealing a container during a sealing cycle. A controller controls the temperature of the heat sealing element during the sealing cycle based on a signal from a temperature sensor that senses the real-time temperature of the heat sealing element. A seal indicator light is provided which is lighted during the sealing cycle and extinguished at its completion. The signal from the controller energizes the heating element for a time to heat the sealing element to a pre-determined temperature for sealing the container and initiates a dwell time corresponding to cooling the heating element after sealing the container. Values of the real-time temperatures of the heat sealing element and values of the sealing times and the dwell times that correspond to the values of the real-time temperatures of the heat sealing element are stored in a look-up table.
