A dispensing mechanism having an engagement device, a valve assembly, and an actuator. The engagement device can receive a container on a stand. The actuator can be mounted to the stand to move the stand in an axis parallel to a height of the container. The engagement device moves the container between a load position and a sealed position. A rim of the container abuts a sealing member of the valve assembly in the sealed position. The dispensing mechanism is pivotally mounted to the hopper. The dispensing mechanism and container are movable together between two positions: the load position, where the valve assembly operates as a lid for the container; and a dispense position, where the valve assembly operates as a lid for the hopper. A valve of the valve assembly is opened to discharge a product from the container while in the dispense position.
