Claim:
1. A vacuum sealing appliance, comprising: a vacuum motor assembly generating suction; a vacuum trough fluidly connected to the vacuum motor assembly configured to receive suction and evacuate a food container through an open end; at least one heat sealing element adjacent the vacuum trough configured to heat seal the open end of the food container after evacuation; a control unit configured to control the vacuum motor assembly and the at least one heat sealing element; and a sensor connected to exhaust tubing of the vacuum motor assembly and electrically connected to the control unit, the sensor configured to detect moisture in exhaust air of the vacuum motor assembly and send electrical signals to the control unit, the control unit controlling one or both of the vacuum motor assembly and the at least one heat sealing element based upon the electrical signals; wherein the sensor generates the electrical signal when moisture is detected in exhaust air of the vacuum motor assembly, which is indicative of liquid being drawn out of the container during evacuation, to cause the control unit to increase heat seal time of the at least one heat sealing element to compensate for liquid in a seal area of the food container caused by evacuation.
