7.4 Ingredient Dispense
1. The ingredients required for making up either an instant or freshbrew drink are
contained in ingredient canisters and are dispensed by means of an auger located
in the base of each canister. Each auger is driven by a 24v DC motor.
2. The amount of product dispensed by each canister is controlled by the vending
machine controller and may be adjusted via the Selection Timers menu in the
engineers program - see page 31 for further details.
3. The required ingredients for each vend are delivered to a mixing bowl, where they
are blended with hot water by a high speed whipper prior to discharge at the
dispense head.
4. To ensure a free flow of ingredient powder and granules, it is essential that they
are kept completely dry. This is achieved by extracting steam from the mixing
system using an extract fan. The electrical supply for the extract fan is 230v AC.
N.B. The fan runs continuously whilst the cabinet door switch is in the on
position.
5. Espresso (B2C) machines: Coffee beans are stored in a bean container and
are dispensed into the CoEx® Brewer via a 230v AC grinder located under the
bean container outlet.
The amount of beans dispensed from the container is controlled by the vending
machine controller and may be adjusted via timing constraints set in the Engineers
Program - see page 31 for details.
7.5 Mixing System
1. The mixing system utilises a 24v DC 13,000 RPM motor assembly and mixes
ingredient with hot water from the heater tank to make a drink.
2. The mixing units are front mounted and secured by a single fixing screw. For
servicing, the complete unit can be quickly and easily removed from the front of
the machine.
N.B. An illustration showing the parts breakdown for the Mixing System is
included in Section 12 - page 163.
