Abstract: A batch system wherein a constant, metered flow, is established for each of the ingredients of the batch. Having a constant flow rate and constant pressure in the fluid flow, a diverter valve diverts the flow for a predetermined length of time to yield a predetermined volume of each ingredient. Since each ingredient is in a separate flow path, the diverter valve can provide one ingredient at a time, or a plurality of ingredients at a time. A computer controlling the system stores various recipes or batch formulas.
