<p>A vacuum transfer method and system for transferring liquid food grade product vacuum transfer system for transferring liquid food grade product into and from a vessel. The vessel has at least one product inlet/outlet. The vacuum transfer system includes a selectively activatable vacuum source. A vacuum transfer unit is in fluid communication with the vacuum source and with the vessel. Valving means are operably coupled to the vacuum source and the vacuum transfer unit for selectively (a) pressurizing the tank and (b) drawing a vacuum in the tank, whereby drawing a vacuum by the vacuum source in the vessel acts to draw the liquid food grade product into the vessel through the at least one product inlet/outlet and pressurizing the vessel acts to expel the liquid food grade product from the vessel through the at least one product inlet/outlet.</p> |
