A method and apparatus whereby livestock and poultry are administered feed additives in their feed ration. The apparatus stores additive concentrates separately until just prior to use, then on demand dispenses the additive concentrates into one or more weigh hoppers for weighing therein. The weighed contents of the weigh hoppers are discharged into a liquid carrier within a mixing vessel where the dispensed additives are diluted, suspended, and dispersed by mixing. The resulting carrier-and-additive slurry is pumped to a receiving station for mixing with a feed ration. The weighing components are isolated from movements that would affect additive weight determinations during the weighing process so that accurate measurements of additive weights are obtained. Dispensing and weighing of multiple additives within a single weigh hopper are sequential. Each additive may be weighed and discharged from the hopper individually or cumulatively with other additives. With multiple weigh hoppers, dispensing, weighing and discharge of additives from the different hoppers can occur simultaneously or independently. A programmable control can program the apparatuses for dispensing either entirely on a weight basis, partly on a weight basis and partly on a metering basis, on a weight-compensated metering basis, or entirely on a metering basis if the weighing means malfunctions.

Programmable apparatus and method for delivering microingredient feed additives to animals by weight

A computer-based microingredient inventory accounting system and process for use with programmable microingredient dispensing and mixing machinery. In the illustrative embodiment, the computer-based microingredient inventory accounting system is coupled with a programmable microingredient dispensing and mixing system. The programmable microingredient dispensing and mixing system includes weight measuring mechanisms that are interfaced with a computer system programmed to continuously monitor the weight of microingredients stored on a plurality of inventory storage scales, as well as in a plurality of dispensing bins and tanks. The computer-based microingredient inventory accounting system is programmed to perform a number of inventory monitoring functions including: automated detection of microingredient loss (e.g., spillage) after each inventory receiving operation and each dispensing bin and tank refilling operation; automated detection of microingredient-usage errors after each micro-batch production run; automated production of inventory reports when arbitrarily requested; and automated tracking of microingredients using the lot numbers of the microingredient supplier. In the preferred embodiment, the computer-based microingredient inventory accounting system cooperates with a portable auxiliary computer and bar code symbol reader in order execute interactive routines which facilitate system configuration, inventory receiving operations, and dispensing bin and tank refilling operations.

Intelligent system and process for automated monitoring of microingredient inventory used in the manufacture of medicated feed rations

A method and apparatus whereby livestock and poultry are administered feed additives in their feed ration. In one disclosed form, the apparatus stores additive concentrates separately until just prior to use, then on demand dispenses the additive concentrates separately and sequentially into a weigh hopper for sequential, cumulative weighing therein. The weighed contents of the weigh hopper are deposited into a liquid carrier within a mixing vessel where the dispensed additives are diluted, suspended, and dispersed by mixing. The resulting carrier-and-additive slurry is pumped to a receiving station for mixing with a feed ration. The weigh hopper is isolated from movements that would affect additive weight determinations during the weighing process so that accurate measurements of the additive weights are obtained. A computerized control system controls the operation and sequencing of the apparatus. In another disclosed form, the apparatus dispenses additive concentrates by weight directly into a mixing vessel by measuring the loss-of-weight of their respective storage containers. In still another disclosed form, the apparatus dispenses some additive concentrates by weight and others by volume into a mixing vessel.

Programmable weight sensitive microingredient feed additive delivery system and method

Programmable apparatus and method for delivering microingredient feed additives by weight

Control for a multiple batch process for preparing product from a plurality of constituent ingredients, in which an error in one batch from the multiple batch is equally divided over the subsequent batches so that all of the remaining portion of the multiple batch can be used and the resulting product is uniform. In the process of preparing product from a plurality of constituent ingredients, a batch of certain of such ingredients is mixed in a receptacle, sequentially divided into substantially equal portions and transported to an apparatus for combination with certain other of such ingredients for preparing the product. The error compensating control comprises an intermediate chamber in flow communication with the receptacle and the apparatus. A predetermined portion of the mixed batch is transferred from the receptacle to the intermediate chamber, where it is weighed, and then delivered to the apparatus. The weight of the delivered portion of the mixed batch is compared with a predetermined desired portion of the mixed batch to determine any error between the delivered portion and the predetermined desired portion. If there is an error, the error is divided by the remaining number of substantially equal portions of the mixed batch to establish a new predetermined portion of the mixed batch. The transfer of subsequent predetermined portions of the mixed batch is then adjusted to the newly established predetermined portion.
