
The upper transmission group (located under the head cover (2) rotates both the spiral tool (3)
and the bowl (5). A main, powerful motor, by means of low-stretch belts and a system of
pulleys, supplies the spiral with the necessary torque, while a separate motor drives the bowl,
permitting it to rotate in both directions.
In the standard line of removable bowl mixers the spiral transmission is direct, composed of two
pulleys (one for the spiral tool motor and one for the spiral tool itself).
A reinforced version, for extremely stiff dough or dough with a high-gluten content, is available
with a double spiral transmission (i.e. the spiral transmission is equipped with an intermediate
pulley (3 in all) to increase the power transmitted to the spiral tool itself.

The spiral tool (3), as a result of its shape and movement, amalgamates, mixes and refines the
ingredients by pushing them against the breaking column (4) and the sides of the bowl (5).

The bowl (5), as a result of its rotation, constantly brings dough still to be kneaded under the
spiral tool. A special thrust roller unit (composed of one friction wheel assembly (13) in the 80-
120 kg models and two friction wheels assemblies (13) in the 160-280 kg models) guides the
bowl rotation, while the milled border of the bowl guarantees the necessary grip, even in the
presence of fat mixtures.

The side control panel (10), located on a special arm above the electrical cabinet, contains all the
control and program logic. The control panel is movable for ergonomic reasons. It executes
each programmed work cycle and, by means of servomechanisms in the electrical cabinet (6),
located at the side of the machine, drives the various motors in the programmed manner for the
programmed time. The unit composed of the control panel and electrical cabinet can be placed
on the right- or on the left-hand side of the machine, as per the client’s requirements.

The hydraulic unit is located inside the base of the machine. It controls the ascent and descent
of the machine head and the movement of the hydraulic hook (7) which holds the bowl carriage
(11) securely in place against the machine.

The safety covers for the bowl (8-9), for the upper transmission group (2) and for the lower
transmission group (not visible because located under the base) serve to protect persons from
accidentally coming into contact with the moving members of the machine.

The movable safety bowl cover (9), if opened during a work cycle, stops the machine by means
of a microswitch.
The adjustment of the minimum opening of the movable bowl safety cover required to
activate the microswitch is carried out by the manufacturer, in the manufacturing
location, during the machine test phase. Any subsequent modification to the original
manufacturer settings can only be carried out by the manufacturer’s authorised
personnel.

The cover (12) serves to protect against risks of squashing and cutting.

All machine movements can be stopped by pressing the Emergency button located on top of
the control panel box.
General machine operation
After having correctly installed the machine, it is necessary to select the work cycle required (i.e. set the
type of operating mode and the corresponding operating times). Place the water, flour and the other
ingredients necessary for the dough into the bowl in the required quantities (not exceeding the
maximum quantities allowed – refer to Appendix 2). Insert the bowl carriage into the machine, lower
the machine head, ensure that the movable bowl cover is closed and start the machine by pressing the
Start button. The machine carries out the work cycle in the selected manner for the set time. Upon
completion of the work cycle the machine head opens and the bowl carriage is released. It is possible to
stop the machine at any time by pressing the Stop button and to start it again by pressing the Start
button. The detailed description of the control panel and its use is described in detail in Appendix 1.
