Milkshake makers are a must-have for any ice cream parlor, café, or bar that wants to treat its customers to frozen drinks. These machines can be mounted on the wall or counter for stability, and have one, two, or three spindles, which give them their other name of spindle mixer, that can whir away at speeds up to 25,000 RPM to blend your drinks to smooth perfection. Their powerful motors range in from 1/3 to 1 full HP. Typically, the spindles are made of rugged, durable die cast metal, for long lasting dependability. Stainless steel mixing cups are generally included, but many are designed to be safely used with plastic cups, as well.
