Continuous dry parts metering and blending system

A continuous dry parts blending system for use in producing beverages. The system continuously adds one or more flowable dry particulate solids to a continuous liquid main product feed stream. Selectively variable particulate solid feeders supply the particulate solid to the liquid feed stream. Mixers are used to help dissolve the particulate solid. A control system and sensors are used to maintain selected concentrations of each particulate solid in the liquid feed stream. Each particulate may be directly added to the continuous main product feed stream, or may be premixed with another continuous liquid feed stream prior to admixture with the main product feed stream.
