ABSTRACT:
A method and apparatus for automatically and simultaneously weighing and integrating various nutritional supplements for subsequent blending with livestock feed grain. The apparatus includes a housing formed with a plurality of upper inlet openings and a lower outlet opening. A plurality of augers convey nutritional supplements from a storage area into the inlet openings. A plurality of weigh hoppers are pivotally mounted below the inlet openings on load cells. Weight indicators are electrically connected to the load cells and augers, and are interfaced with a computer, for controlling and coordinating the deposit of supplements from the augers, load cell weighing, and the pivotal dumping movement of the weigh hoppers. A funnel containing a plurality of deflectors is mounted within the housing below the weigh hoppers, and communicates at its lower end with a motor-driven flighted drum rotatably mounted within the housing, which in turn communicates with the outlet opening. The method of the invention includes the step of automatically and simultaneously metering the supplements into the weigh hoppers through the augers. The supplements then are automatically and simultaneously weighed and dumped into the funnel. The supplements travel downwardly by gravity through the funnel and deflectors which combine to integrate and guide the supplements into the rotating drum. The drum further integrates the supplements and urges the supplements from the drum and out of the outlet opening into packages for transport to a feed manufacturer. The feed manufacturer then blends the integrated supplements with feed in a batch blending apparatus.
