5 DESCRIPTION OF THE MACHINE AND ITS USE
Intended use of the machine
The product line of this spiral mixer is designed for kneading dough from the food industry, whose main ingredients
are flour and water. A rotating spiral mixes, mixes, refines and kneads quickly and easily through the powerful
mechanical work of the mixer, injecting air into the dough contained in the bowl. Originally intended for the preparation
of bread dough, the blender was subsequently also found to be suitable for sourdoughs and bakery products
consisting of the following ingredients: any kind of flour, yeast, fats / butter, sugar, officially approved food flavors and
food colors, salt, liqueurs and other ingredients suitable for bread and confectionery products. The mixer line is not
suitable for mixtures with a moisture content of less than 55%. The maximum time interval for continuous use and the
corresponding minimum downtime for this mixer differ depending on the recipe used (type of dough to knead);
Therefore, the user must contact the manufacturer for this information with the recipe.
Percentage of ingredients
Based on the percentage of each ingredient, there is a maximum amount of each ingredient that can be added to the
bowl so as not to exceed the maximum amount of dough specified for the blender.
For additional information about the maximum amount of dough and the percentage of flour for a particular mixer, see
Appendix 2.
Machine structure
The mixer consists of the following components:
• A durable stainless steel body (reinforced with metal profiles at locations where mechanical stress is greater)
incorporates and supports the various machine components.
• The upper drive group (seated under the head cover) turns the spiral. This movement is generated by a durable,
forged shaft mounted on a ball-bearing flange.
• The spiral mixes and refines the ingredients by their shape and movement by pushing them against the column and
sides of the bowl.
• Due to its movement, the bowl ensures that the dough is continuously kneaded under the spiral.
• The control panel located on the head cover contains the control and program logic. It performs every programmed
duty cycle and drives the various motors in a programmed manner for a programmed time due to the servos of the
electrical panel.
• The lower drive group (seated inside the base plate) turns the bowl. This movement is generated by a durable,
forged shaft mounted on a ball-bearing flange.
• The safety covers of the bowl and the upper and lower drive groups (invisible due to the seat under the base plate)
protect persons from accidental contact with the moving parts of the machine.
• The mobile safety cover stops the machine via a microswitch when opened during a work cycle.
AThe minimum opening of the mobile safety cover required to activate the microswitch is set by the
manufacturer at the place of manufacture during the machine check. Any subsequent modification of
the manufacturer's original settings may only be carried out by personnel authorized by the
manufacturer.
General machine operation
After proper installation of the machine, it is necessary to select the required working cycle (eg the operating mode
and the corresponding operating times - see Annex 1). Put the water, flour and other ingredients necessary for the
dough in the required quantities in the bowl (do not exceed the maximum permitted - see Appendix 2). Lower the
mobile bowl cover and start the machine by pressing the start button. The machine goes through the work cycle in the

1 2 PROCEDURES IN OPERATION
ATTENTION! Strict compliance with the safety measures and local safety standards specified in this manual is
essential for carrying out all work with the machine.
• Preparatory machine check
• Check the following before starting the work cycle:
• The machine is stable on a straight, smooth and solid surface.
• The machine is correctly connected to the power supply.
• The machine parts are clean.
A
Fill in the ingredients to be kneaded
With the machine off, it is possible to gain access to the bowl by simply lifting
the mobile bowl protective cover (A).
Check that there are no foreign objects in the bowl and it is clean. Put the
ingredients (only products that are suitable and approved for the production of
bread and confectionery products) in the bowl. Observe the maximum
quantities permitted for the corresponding machine (Appendix 2).
The recommended order for filling the ingredients is as follows:
1. Dispatch the required amount of water into the bowl.
2. Put the flour into the bowl(in correct proportion to the water).
3. Then add other ingredients for the dough (salt, raising agent, butter,
margarine, etc.) by lifting the mobile bowl protective cover and placing
the ingredients in the bowl. If the mobile bowl cover is raised while the
machine is in operation, the machine will stop. It is therefore necessary
to close the mobile bowl cover and restart the machine to complete the
cycle. Add small amounts of ingredients to the dough by adding them
directly through the opening (s) in the mobile bowl cover without
opening the lid itself.
The operator is strongly advised to add the flour to the bowl after filling with water, otherwise the dough will
form high-density lumps which will cause the machine to function irregularly resulting in a sudden increase in
performance which will shorten the life of the drive belts and generally causes the wear of wearing parts.
Performing a work cycle
It is only possible to start the machine when the mobile bowl protection cover (A) is closed.
Appendix 1 contains a detailed description of the control panel, its functions and how to program and execute
a work cycle.
All machine commands required to complete a work cycle are
located on the control panel.
• The start button starts the set work cycle.
• The time countdown of the performed duty cycle is displayed on
the control panel's digital display or LED (depending on the type of
control panel).
• If the mobile bowl protection cover is opened, the duty cycle will be
interrupted. To continue the work cycle, put down the cover again.
• The Stop / Emergency Stop button stops and resets the duty cycle.
The time display returns to the initial setting of the last executed
duty cycle.

19
Warnings regarding repeated interruptions to a work cycle
Once the cycle has been started by pressing the start button, the machine continues to knead the dough until the
set working time has elapsed unless the operator breaks the cycle. Avoid repeated interruptions to the duty cycle,
as this will overheat the engine, which may affect the machine's efficiency in the long term.
Stopping the machine
The timers automatically stop the work cycle and thus the machine as soon as a programmed time has elapsed.
The machine can be stopped at any time by pressing the STOP / EMERGENCY button. Nevertheless, it is
strongly recommended to avoid repeated interruptions by the operator. To turn off the machine, turn the main
switch to the "O" position.
Remove the kneaded dough
After completion of the working cycle, it is possible to remove the dough after opening the mobile bowl protective
cover from the bowl. It is strictly forbidden to use objects that can scratch or damage the machine.
