TECHNICAL DATA
KNOWING THE APPLIANCE
This appliance has been designed and built for food use only, for the cold pro-
cessing of cereal flour-based doughs; its main use is therefore in pizzerias, bak-
eries and pastry shops.
The purpose of the machine is to round portions of already portioned dough to
the desired weight, while maintaining the basic characteristics of the dough
unaltered; the action carried out by the screw determines the advancement of
the dough and the consequent compression of the same against the ribbed
surface of the cylinder from which, once it comes out, it will be very compact
and with good roundness.
Fig.3 The main parts of the machine are:
1 Auger
2 Tray: accommodates the rounded dough balls
3 Cylinder
4 Emergency STOP button
Pressing the red STOP button switches off the machine and stops the ro-
tary movement of the cylinder. It must therefore be used only when really
necessary and not as an ON/OFF switch to be used at the end of the work
day. If pressed, to restore the conditions of use, unlock the button by turn-
ing it clockwise
5 Control panel - ON/OFF keys
- black button 0: machine stop
- white button I: machine start
- central light: if on, it indicates that the machine is on
6 Wheel with brake: during normal use, always keep the appliance blocked
by lowering the brakes of the front wheels.

PROBLEMS DURING USE
During use, some problems may occur that can be easily solved following the instructions detailed below.
PROBLEM FOUND PROBABLE CAUSES SOLUTIONS FOR THE USER
The dough balls stick to the auger
and find it difficult to get back up The dough is too hydrated Use doughs with hydration from 50 to 65%
Dough balls do not stick to the
auger but find it difficult to get
back up
The dough is not very hydrated Use doughs with hydration from 50 to 65%
The dough was left in the air for a long time
and dried up Once the dough is portioned, start rolling quickly
The portion of dough that goes into the auger
is too large
Comply with the following instructions:
Model Dough size Dough
hydration
minimum maximum
BRN280 20 g [0.044 lb / 0.70 ounces] 300 gr [0.66 lb / 10.58 ounces] from 50 % to 65 %
BRN800 20 g [0.044 lb / 0.70 ounces] 900 gr [1.9 lb / 31.7 ounces] from 50 % to 65 %
The portions of dough were floured before
being inserted into the auger Do not flour the dough portions
The lower disk under the auger
must be cleaned Remove and clean it
The rounded ball is much larger
than the amount of dough inserted
The portions of dough were inserted too quickly
one after the other inside the auger and joined
together Increase the time between inserting one portion of dough and the next
The surface of the ball formed is not
smooth and has imperfections
The dough did not rest long enough before
portioning Increase the resting time of the dough before portioning it
The dough is too hydrated Use doughs with hydration from 50 to 65% or, alternatively, cool the dough to about
10°C (50°F) before inserting it into the auger of the rounding machine
The leavening of the dough, made in the
refrigerator, took place before the balls were
formed (rising/mass leavening).
Use doughs with hydration from 50 to 65%. Leavening in the refrigerator must take
place after forming the balls.
After pressing the ON/OFF button,
the machine does not start
The appliance has been stopped pressing the
emergency button To reset the normal operating conditions, unlock the emergency button rotating it clockwise and restart the machine with the ON/OFF button
The machine is not powered Make sure that the plug is correctly inserted into the socket and that there are no
interruptions to the electricity supply (e.g. black-out)
Some component is broken Contact the Dealer
