Abstract
A multiplicity of variable density fluid streams, each having been processed to yield individual fluid streams of desired densities, are combined in a manner to achieve controlled ratios of each stream as determined by a recipe structure to produce a final mixture of a desired density. This system further allows injection of solids or other pumpable fluids utilizing the same overall control equipment, compensating for displacement to again yield a final mixture to meet a desired weight per unit volume. This system may be utilized to manufacture a variety of products, especially edible foods such as frozen toppings, marshmallows, ice creams and other comestibles. The overall control system hardware may be extended to further control related aspects of process equipment such as heat exchange functions, flowrate, level, pressure, and the like, as may be required to achieve economical utilization of the microprocessor capabilities.
