Abstract
A vacuum sealing appliance is provided including 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, and at least one heat sealing element adjacent the vacuum trough configured to heat seal the open end of the food container after evacuation. The vacuum sealing appliance further includes a control unit configured to control the vacuum motor assembly and the at least one heat sealing element. The vacuum sealing appliance further includes at least one channel disposed proximate the heat sealing element. The channel is fluidly connected to a cooling fan that generates a cooling air flow through the channel to remove excessive heat from the heat sealing element to prevent premature sealing of subsequent food containers between heat sealing events.
