7.9 CoEx® Brewer (B2C Machines)
The unique CoEx® combined coffee and espresso brewer provides both freshly
brewed coffee along with fresh coffee from beans through the same unit. The unit is
driven by a 24v DC, 13 RPM motor, controlled by a micro switch. The switch sends
logic signals to the controller during vend and initialise operations, indicating its
position.
Please refer to Section 8 for full details of the CoEx® brewer and its operation.
7.10 Teapot
The teapot is a pour over style brewer with a double rotation ‘dump’ mechanism.
The unit is driven by a 24v DC 14 RPM motor and controlled by a micro switch.
Tea Brewing
Water and tea are dispensed into the brewer, the water is dispensed in two
parts with a one second paurse between. This is to allow the tea to steep
hence giving a fuller flavoured drink. When the water valve turns off the brewer
waits for 7 seconds to allow all the liquid to exit the brewer. At this point the
brewer rotates twice, dumping the used tealeafs into the brewer waste
container.
7.11 Power Supply Unit
1. The power supply unit (PSU) provides power to the machine. It is
mounted on the PSU chassis on the left hand side of the machine and can
be accessed by removing the lower front panel.
2. The PSU converts 230v AC to 24v DC to run the valves, whipper motors,
ingredient motors, brewer motors, etc. fitted to the machine. The solid
state relay, mounted on the PSU chassis, uses a 24v DC switching circuit
to provide 230v AC for the heater element.
3. The Input/Output (I/O) board, mounted on the PSU chassis, utilises signals
from the main controller in order to operate valves, whipper motors, the
dispense head motor, ingredient motors, brewer motors, etc.
4. The PSU houses three fuses. These are as follows.
●
Heater, 12 amp T (ceramic)
●
240v Auxiliary, 4 amp (glass)
●
240v PSU, 4 amp (glass)
N.B. An illustration showing the parts breakdown for the PSU is included in
Section 13 - Spare Parts (see page 175).
