Abstract
An apparatus for blending commodities in a commodity handling system which includes containers (46) for holding the various commodities, the containers (46) having discharge means for enabling commodities to be discharged from the containers, and conveying means (43) for moving the commodities from one location to another is disclosed. The blending apparatus includes means for selecting the containers (46) whose commodities are to be blended together. The selection means also includes means for selecting the relative percentages of the commodities to be blended. In addition, there is means for determining the corresponding amount of opening for the discharge means such that the required blending percentages are obtained. Additionally, there is control means for opening the discharge means the required amount to achieve the selected blending percentages. The control means includes a master cylinder means (42) interconnected to a plurality of slave cylinders (44), slave cylinders (44) being operatively interconnected to the discharge means.
