Abstract
A uniform small particle homogenizer for liquid product comprising a pair of intensifier cylinder pumps (20) driven by a hydraulic system (22). The pumps have a power stroke side and a suction stroke side, and a pair of proximity sensors (24) that interface with each pump to detect forward and rearward movement. A microprocessor (26) with timing capabilities controls the sequential operation of each pump with the power stroke of each pump timed to alternately produce a flow of the liquid product with a precisely timed flow overlap period from the alternating pumps. Since the power stroke takes a longer time than the suction stroke, the instant each power stroke is started the opposite pump is timed to hesitate and slightly overlap until a constant product flow-rate is produced from the alternating pumps, which eliminates large variances in pressure and therefore achieves uniformity in product particle size.
