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 machine has power.
5. 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.
7.4 Mixing System
1. The mixing system utilises 24v DC 13,000 RPM motor assemblies and mixes
ingredient with hot water from the heater tank.
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.
7.5 Moving Dispense Head
1. Voce machines are fitted with a moving dispense head mechanism. This allows for
a quicker and more direct cup drop and also helps to prevent cross contamination
of drinks. The head features two separate dispense positions depending upon the
drink being dispensed.
2. The mechanism is operated by a 24v DC 48 RPM motor. The motor is connected to
a pinion which engages with a rack on the dispense arm. This mechanism is used
to move the dispense head backwards and forwards.
3. A micro switch, fitted to the rear of the dispense head chassis detects the home
position (head withdrawn/not dispensing). An optical sensor is also fitted and this
works in conjunction with a decoder bracket attached to the rack to determine the
position of the dispense head.
4. A moulded dispense head mounted at the front of the unit connects the tubes
from the various mixing systems, brewers and hot water, to separate dispense
nozzles.
N.B. Dispense pipe lengths are shown in Section 9.
7.6 Cup Dispense Unit
1. Cups (either paper or plastic) are stored in tubes which are located above the cup
dispense unit. The unit incorporates a 24v DC, motor for Indexing the correct turret
over the cup drop unit as required.
2. The cups are separated and ‘dropped’ by a cup ring. The cup ring comprises five
separator cams operated by a 24v DC motor, which is controlled by the vending
machine controller.
