Abstract: A system for attaching a food processing adapter to a food processing unit includes an upper processing adapter attached to a pressure assembly of the unit, and a lower processing adapter attached to a holder at a base of the unit. The holder includes a first slot extending horizontally into a top portion of the holder, and a second slot opposite the first slot and extending vertically into the holder. A first tab extends horizontally from the lower processing adapter and is configured to be inserted into the first slot. A second tab extends vertically from the lower processing adapter so as to be inserted into the second slot. A locking mechanism is configured to releaseably lock the second tab in place to prevent movement of the lower processing adapter during operation of the food processing unit.
