Appendix 5 : RECOMMENDATIONS FOR THE ADJUSTMENT AND THE
MAINTENANCE OF THE APPARATUS
Breaking
■ Distributor
Distributor adjustment:
3 mn (±15 s) for 500 g of wheat at 15,5%
The Beryllium plate should be at the right hand side
■ Cylinders spacing
120/100
The cylinders are grooved, then
they undergo a thermal treatment
ensuring a great metal hardness.
12/100*
(*) ± 0,02
■ Centrifugal sieving chamber
N° 120
150 µ
inox
1.
Sifter in a good state but slack for the sieve
cleaning.
2.
Check the wearing of the blades, the spacing
between the blades and the sifter (approx.
2 mm theoritical dimension at standstill).
3.
Adjustment of the blades on
the last 2 beaters 
(can be performed on 1 or 2)
1: maximum slow down
2: intermediate position
3: maximum speed up
4.
Centrifugal sieving chamber emptying time:
1 mn 30 ± 15 s
■ Break flour standard yield on local wheat
mixing
Generally, 20 to 35% according to the nature of the
floury kernel.
Sometime, it may rise to 40% and more.

Reducing
■ Distributor
Distributor adjustment:
3 mn (± 30 s) for 250 g semolina of local wheat
The Beryllium plate should be at the right hand side
■ Smooth Cylinders
1.
Check the mobility of the equipment and the
contact of the two smooth cylinders.
2.
Check the condition of the top and bottom
scrappers which should be "free" and ensure a
perfect cleaning of the cylinders.
■ Centrifugal sieving chamber
N° 100
170/180 µ
inox
1.
Sifter in a good state but slack for the sieve
cleaning.
2.
Check the wearing of the blades, the spacing
between the blades and the sifter (approx.
2 mm theoritical dimension at standstill).
3.
Adjustment of the blades on the last 2 beaters:
proceed in the same way as for breaking
However, the centrifugal sieving chamber is fit-
ted with adjustables blades on the last 4 beat-
ers. Adjust first the last 2 the same way as for
breaking, then, if required, the next 2 beaters.
4.
Sieving chamber emptying time :
1 mn 30 ± 15 s
■ Reduction flour standard yield
1 reducing operation :
-----------------------------
semolinas
2 reducing operation: 70 to 85%
■ Effect of the adjustment on W and P
The pressure rise at reducing stage will increase the
P value of the Alveograph and vary the ratio P/L.
Use the additional weights (square) provided with
the machine.
