  • Patent number: 8033430
    Abstract: The embodiments of the present invention are directed to a dispensing apparatus for dispensing a flowable product at or above a preset elevated temperature through a dispensing outlet. Such an apparatus includes a pot in which to house the product. The dispensing apparatus also includes a pump coupled between the pot and the dispensing outlet to pump the flowable product from the pot to the dispensing outlet. A rope heater configured to heat the pot may also be included in the dispensing apparatus. The pot may have a movable lid, which may vacuum seal the product against the exterior environment. The lid is designed to scrape any food product residue off the vertical walls of the pot, while also maintaining the vacuum as it moves into the pot. The pot may have a check valve to prevent product spilling when the pot is lifted out of the housing.
