1.3.1 USE
The mod. «IRIS» dough mixer has been
exclusively designed for the use of mixtures of
various types of flour available on all the
international markets, in authorized work
environments and small industries such as:
bakeries, pizza restaurants and confectioners’
shops.
1.3.2 DESCRIPTION
(The numbers between brackets refer to Fig.1).
The machine mainly consists of a robust metal
bearing structure (10) equipped with two drive
units: an upper one (14), which turns the dough
tool. and a lower one (15), which drives the
bowl (18). The rotational movement of the IRIS
30-40 dough mixer is controlled by a single
motor. The electric panel is situated under the
upper cover, which also closes and protects
the machine. In both the drive units, the actual
drive is transmitted by V-belts, the tension of
which is regulated by belt stretchers. The
dough mixer’s functions are controlled by a
control panel (3), which is described in section:
«4.1.1 Control panel».
The work cycle can be programmed by means
of two timers, which allow the dough mixer to
automatically switch from the first to the second
speed. The bowl can be turned at first speed by
means of a selector, i.e.: NORMAL (anti-
clockwise direction), REVERSE (clockwise
direction), or bowl at a standstill. Drive reversal is
not available for version 30-40, thus the relative
selector is not installed. During the first phase,
the ingredients are mixed together so as to obtain
a homogeneous dough. As the consistency of the
mixture and the speed of the dough tool increase,
the dough is finished and fully blended in the
second phase. At the end of the process, the
operator can switch the selector to the reverse
rotation position (opposite to the direction of the
normal cycle, i.e. clockwise) to detach the dough
from the dough tool while bringing it to the center
of the bowl so that it can be easily cut and
removed.
WARNING
The Manufacturer declines all liability for
direct and indirect damages to persons,
animals or property caused by the machine
having been used for purposes other than
those described in this manual (see 1.3.2
Use).
1.3.3 SAFETY DEVICES
WARNING
The electrical system of this machine has
been built in compliance with the current
standards, particularly standard EN 60204-01.
The electrical system is equipped with a device
that protects against overloads and includes a
thermic relay and protective fuses (consult the
wiring diagram supplied separately).
To safeguard the operator, the grille (4) prevents
the limbs from accidentally accessing the bowl
interior when the dough tool is turning. The bowl
and dough tool will immediately stop if this grille is
raised when the machine is running. The electric
panel is also protected by a key-operated lock. In
versions 80-250, the access door has a key-
operated lock (9) and a main switch (20) with
