Multiplex Post-mix Beverage System
Multiplex Post-mix beverage systems use filtered water from a filtered water supply system
and chill it as it passes through stainless steel cooling coils located in an ice cold water bath.
The water bath is maintained at 32°F (0°C) by a mechanical refrigeration system which
produces a large ice bank reserve to provide sufficient cooling for peak draw periods. This ice
reserve allows a relatively small refrigeration unit to maintain drink temperatures, drawing form
the ice reserve during heavy load periods and then re-establishing the ice bank during light draw
periods.
The chilled water passing through the water bath is mixed with carbon dioxide (CO
2) in the
carbonated water supply system. This is when and where it becomes carbonated water in the
carbonation tank.
Syrup is also chilled as it passes through stainless steel cooling coils located in the ice cold
water bath. Chilled, the syrup is connected to one of several beverage tubes contained within a
beverage conduit. This conduit is then routed to a dispensing station.
The circulating carbonated water supply system allows for the circulation of carbonated
water through use of a pump to create an outlet and inlet carbonated water supply. Outlet and inlet
carbonated water supplies are connected to tubes contained within the same beverage conduit as
the syrup. This allows carbonated water to flow from the water bath to the dispensing station and
back, maintaining a constant beverage temperature throughout the system.
Ice cold carbonated water and syrup are dispensed from valves at the dispensing station.
Dispensing valves contain flow controls which allow for flow adjustment to maintain the proper
ratio of syrup to carbonated water. Syrup and carbonated water are released when the dispensing
valves are opened. This allows mixing to begin as escaping products are allowed to flow through the
valve nozzle. They continue to mix as they fall into the customers cup to complete the production
of a bottler-quality soft drink.
