Abstract
The present invention provides an improved frozen beverage dispenser overcoming the disadvantages of the prior art noted above. Not only is the beverage dispenser relatively simple to construct and maintain, but it also provides an exceptionally fast freeze down time and accurate monitoring and control of the thickness of the slush dispensed from the beverage dispenser of the invention. The components of the beverage dispenser of the invention are housed within a compact housing incorporating solid state design with few mechanical moving parts. The closed loop system includes an evaporator, heat exchanger, condenser, compressor, and a filter/dryer. A tank feed system directs the beverage mix to a cylindrical mixing chamber having a rotatable beater bar located therein. The beater bar is coupled to a direct drive control system which monitors and controls the thickness of the slush formed in the mixing cylinder. The mixing cylinder is provided with a rear seal mount assembly which permits quick connect and disconnect of the beater bar from the mixing cylinder.
