Abstract
A precision measurement dispenser provides for storage of a granular bulk material in a storage container that is preferably airtight. The granular material is held in a storage container which feeds a dispensing section that is preferably positioned within the storage container. The dispensing section selectively dispenses the ingredient by gravity to a weighting tray of a scale. The ingredient is dispensed by weight. The storage dispensing unit may also include a display and keypad for entry of a desired quantity of ingredient to be dispensed, and optionally which of plural ingredients to be dispensed. A controller can convert a requested volumetric measure to an equivalent weight measure, and dispense by weight in place of volume. The storage dispensing unit further optionally includes pressure control, temperature control, and/or humidity control on the storage container. The dispensing section uses screw, roll, vibration, or shuttle mechanisms for precise dispensing of material.
