Abstract
Abstract 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.
