Laboratory Mill CD1
Proceed in the same way as for alveograph milling with this
difference
■ for local wheats
2 reduction stages (one more than before)
■ for vitreous wheats
3 reduction stages (again one more run than before).
Under these conditions, flour extraction is between 65 and 70.
The flour collecting-pans have been designed for 1 kg of milling
output. If more milling output is required, repeat the operation or use
special collectors.
❏ Determining the falling-time of wheat requires grinding the wheat
and obtaining a pulverized product whose granular characteristics
are accurately defined by this method.
❏ It is not possible with a two-break mill to get products similar to
those with the hammer mill recommended for this method.
❏ However, by sifting the milled products delivered by our mill with a
n° 40 plated steel sifter, it is always possible to obtain from the sifter
extraction valuable HAGBERG results which take into account the
reproductibility of the method. The standard method for operating
will be used.
❏ Considering the possible variation of alpha-amylase activity in dif-
ferent grains which make up a sample, we do not recommend going
lower than 200 g of milling weight.
❏ To recover the break product, unscrew the plastic star knobs on
the spout at the junction of the grinder-sifter. Remove the spout and
in its place put the special receiving-pan supplied with the mill.
❏ The grinder was not obviously designed for this purpose. It is still
serviceable when one is handling a series of large quantities.
❏ The bulk composition of the milled product is defined by the
AFNOR VO 3-701 Norm.
❏ The composition of the product obtained with the Chopin Mill cor-
responds to these specifications except for the presence of particles
exceeding 1.7 mm. This does not seem to have any consequence
on the results. The reason for this is that particles which are bigger
than 1.7 mm are in fact "flakes" with very wide bulls but are less
than 1.7 mm in thickness.
❏ The characteristics of the grinder - 3 revolving cylinders mounted
in a heavy case without too much air-space - highly favors this
usage.
❏ Concerning the use of the Mill, proceed in the same manner as
for the HAGBERG.
