– prepare an anti-bacterial cleaning solution with a chlorine base (products
that can be purchased in pharmacies) following the concentrations given
on the product instruction labels.
Before removing the container lower the flap in order to prevent the
accidental escape of the soluble product inside the same (fig. 4.17).
– remove all the product containers from the machine (fig. 4.18).
– remove the lids from the product containers covers and product chutes
(Fig.4.19). Dip all in the solution previously prepared.
– remove all the powder chutes, water funnels, mixing bowls and whippers and
silicone tubes and dip these parts also in the prepared solution (Fig.4.20)
– with a cloth soaked with the solution clean the whipper assembly base
(Fig.4.21)
– the parts must soak in the solution for the time indicated on the solutions'
instruction label.
– Recover all the parts, rinse them abundantly, dry them perfectly and
proceed with the re-assembly in the distributor.
After re-positioning the container undertake to raise the flap in order to reset
the correct function (fig. 4.22).
For further safety after the assembly of the parts, effect some auto-
matic cleaning cycles so as to eliminate any eventual residues.
4.7 Product container loading
4.7.1
Loading containers
Filling is possible keeping the containers inserted, and by raising the upper
flap of the vending machine (Fig. 4.23) or by extracting each container.
For granulated coffee in particular it is necessary to close the closure plat
before extracting the container.(Fig.4.24).
– remove the covers of each container and load the product according to
the product indicated on the label (Fig.4.25).
– pay attention that they there are no clots, avoid pressing the product
and using an excessive quantity, so as to avoid its aging in relation to the
consumption forseen in the time period between two loadings.
Check the container product capacity in the section TECHNICAL CHARAC-
TERISTICS.
4.7.2
Payment system installation
The vending machine is supplied without any payment system:
The installation of the payment system is the responsibility of the installa-
tion technician.
Current validator 12-24V arrangement for Executive Systems/MDB kit pay-
ment systems.
Bianchi Industry spa will not take responsibility for any eventual damage to
the machine itself and/or to things and/or persons due to incorrect installation.
Serial "executive" systems require a payment system KIT, which is provided
separately.
Consult chapter "6.0 SOFTWARE INSTRUCTIONS" so as to verify setting of
the parameters, that must be coherent with the system used.

DESCRIPTION OF OPERATION
CUP AND SPOON COLLECTION
The vending machine does not feature an automatic cup and spoon distributor.
The user shall therefore independently see to obtaining them via the ap-
propriate dispenser available in the vicinity of the vending machine and shall
ensure that they are correctly positioned in the dispensing compartment
(fig. 5.1 and 5.2).
It is furthermore possible to request supply of a support element enabling
the positioning of a jug (both available on request) inside the dispensing
compartment, as illustrated in figures 5.3 and 5.4.
SUGAR DISPENSER
The vending machine in its standard version, is not provided with a sugar
dispensing option. The user himself will therefore have to see directly to
sugaring the drinks personally.
INSTANT DRINKS
According to the type drink requested and to the vending machine model,
several of the various processes described here below can be activated.
– The solenoid valve fixed to the espresso boiler is engaged in order to
deliver the required quantity of water into the mixer (fig.5.5).
– The pump that dispenses the quantity of programmed water is activated
and is controlled by an appropriate electronic device (volumetric counter).
– The instant product geared motor activates the helicoidal screw conveyor
so as to dispense the quantity of product programmed into the mixer (in
some versions more than one product can be conveyed into the same
mixer) (Fig.5.6).
– once the preset quantity of water and powder is dispensed, the whipper
motor is switched off.

(with machine off)
ESPRESSO COFFEE
This process only occurs for the versions provided with an express coffee
group.
– the grinder is activated until it reaches the dose of ground coffee set by
the doser (Fig.5.9)
– the doser electromagnet is activated , causing the opening of the door
and consequent fall of the coffee into the brew chamber
– the rotation group geared motor brings it into the dispensing position and
simultaneously compresses the ground coffee (Fig.5.10).
– the pump that dispenses the quantity of programmed water and that is
controlled by a specific electronic device, (volume meter), withdrawing
the water from the coffee boiler (Fig.5.11).
– the coffee group geared motor is activated again so as to bring again
into standby position; during this movement the used coffee grounds are
expelled (Fig.5.12).
The operational sequence (coffee grinding and release) may occur in an
inverse order according to the type of programming involved.
ESPRESSO COFFEE WITH VARIABLE CHAMBER
This process takes place only in models fitted with a variable chamber es-
presso group and timed grinding (Fig. 5.13) (ground coffee dispensed into
the group without mechanical dosing).
Grinding
-
Select a beverage including espresso, the grinding starts for the time
programmed by the operator in the specific doses (Fig. 5.14).
-
The ground coffee falls directly into the infusion cup in the coffee group
(already positioned under the coffee chute) (Fig. 5.15)
Dispensing group
-
The group rotating gear motor activates to place the group in the dispens-
ing position, inserting the piston (Fig. 5.16).
Pressing
-
The coffee pump is activated and the solenoid valve that drives the upper
piston opens, the hydraulic thrust (programmable through adjustment
of thrust pressure) brings the piston into the infusion group, therefore
applying the desired amount of pressure on the coffee dose (Fig. 5.17).
Once compression concludes the loading valve closes.
Pre-infusion (if programmed)
-
Upon conclusion of the pressing phase the machine starts pre-infusion.
The coffee solenoid valve opens until the programmed quantity of water
is dispensed, then the coffee solenoid valve closes.
Once pre-infusion is concluded, the machine checks the coffee pressing
and possible opens the solenoid valve again to correct it, opening water
loading until the proper pressing is reached (See the "Pressing" phase).
Infusion
-
Once the coffee compression phase is concluded, the coffee solenoid valve
opens and dispenses the programmed quantity controlled by an electronic
device (volumetric meter).
Final pressing
-
Once dispensing is concluded the coffee solenoid valve is deactivated,
the water loading valve activates (for a programmed time) to to lower
the upper piston once more, pressing the coffee dose, drying it further.
Any water produced during the final pressing phase is expelled through
the 3rd passage (drain) of the coffee solenoid valve.
Drain
-
Once final pressing is concluded the pressure present in the upper piston
is discharged (the loading solenoid valve closes, and the drainage solenoid
valve opens), to make the piston retract completely.
Return
-
Once the piston has retracted (Fig. 5.18-pos 1) the coffee group gear
motor activates once again to place the group in the standby position,
ready for a new cycle to begin.
-
During the movement the used coffee dose is also expelled (Fig. 5.18-pos 2).
