An architecture is presented that dispenses fresh cooking oil. The dispensing device comprises a rack and a vacuum chamber that secures containers of cooking oil in an inverted position. The vacuum chamber allows the cooking oil to drain out of the container and ensures that all oil is completely drained from the container. A metal cap assembly is secured to an opening of the container, allowing the container to be inverted on the rack. The metal cap assembly comprises a vent hole and a metal tube connected to the vent hole that draws air into the inverted container to prevent vacuum levels from building up in the container. A hose transfers cooking oil from the container to the vacuum chamber. And, an exit hose connects to a pumping station and transfers cooking oil from the vacuum chamber to the pumping station and ultimately to a fryer.
