Abstract

A mixing and dispensing machine for combining fluid diluent and concentrate has a concentrate dispenser, a diluent line, a mixing device having a rotatable mixing impeller and into which the dispenser and diluent line direct ingredients, a single electric motor for driving both of the concentrate dispenser and the mixing device, a reduction gear box connecting the motor to the concentrate dispenser with a slip coupling, and a coupling connecting the motor directly to the mixing device; the coupling is an elongate tube of elastomeric material having a mass greater than the combined mass of the mixing impeller and its shaft and serves as a flywheel, dampener, thermal isolator and electrical isolator between the motor and the mixing device.
