General Description

The Model 6321L is a freezer that dispenses frozen carbonated alcoholic beverages (see photo on front cover). The freezer has two major components, the freezer sections (dispense head) and the product feed system (lower cabinet area). The freezer consists of a freezing cylinder with a rotating internal auger (dasher) that is belt driven by an electric motor. The auger scrapes frozen product off of the inside of the refrigerated cylinder. A torque sensing mechanism controls compressor operation to maintain desired product consistency. The freezer has an air-cooled refrigeration system and is mounted on a product feed base cabinet. The cabinet contains a carbonator, pumps, interrelated tubing, and components to store, mix, and transfer carbonated liquid mix to the dispensing head.

Both the freezer and base cabinet are enclosed in independent steel cabinets. The freezer cabinet panels are easily removed to simplify installation, service and maintenance. The base cabinet has service doors located at the front and back for service and maintenance. Mix out indicator lights notify the operator when one or all of the product mixes are out.

The 6311 Frozen Dispenser is the upper portion of the 6321L only.

Theory of Operation

A CO2 cylinder supplies carbon dioxide gas to an adjustable carbonator regulator and an adjustable CO2 pump regu- lator. The pump CO2 regulator delivers CO2 to both the gas driven alcohol pump and syrup pump. The process starts when plain (tap) water enters a booster pump. The water is then pumped into the carbonator and carbonated. Carbonated water flows through a manual shut-off valve to an electric solenoid that has a flow control. At the same time, alcohol from the alcohol rack, located in the front cabinet compartment, flows to the gas driven alcohol pump. The alcohol is then pumped through a manual shut-off valve to the alcohol electric solenoid with flow control. A gas driven syrup pump draws concentrated syrup from the Bag-In-Box containers located at the bottom, front of the lower cabinet. The syrup concentrate is then pumped through a manual shut-off valve to the syrup's electric solenoid with flow control. If the freezing cylinder pressure drops below 25 PSI, the solenoids open and feed product through a check valve into an accumulator. The carbonated water, alcohol and syrup concentrate are mixed together in the feed line. The mixed product flows from the accumulator to the freezing cylinder.

A clear, self-closing, dispensing valve is attached to the front of the freeze cylinder barrel. A pressure release valve is incorporated into the dispensing valve that allows excess CO2 to be vented when filling the freeze cylinder with product. This pressure release valve will also allow excess pressure to escape the freezing cylinder.
