Preparation of a sample
NOTICE Select a representative sample for the measurement.
For information and notes about sampling, refer to the standard:
DIN EN ISO 24333: 2010 Cereals and cereal products – Sampling
Optimum, repeatable results can be achieved with cleaned samples.
Extraneous components must be removed prior to the measurement!
Measuring temperature
Atmospheric humidity
+10 °C to +45 °C
20 % to 90 %, non-condensing
Measurements below or above the specified measuring temperature are possible, but
represent a risk of inaccurate measurement values!
Allow the product samples to acclimatize to room temperature!
This applies in particular to:
•Frozen samples, because the condition of aggregation of water is significant
for the measurement.
•Hot samples taken during the drying process, for example.
In products with an extreme surface moisture level, drying is required for homo-
genization.
Measurement results from samples that are already releasing a fermentation odour
can display greater errors than freshly harvested samples.
To achieve an accurate measurement result, it is necessary to have a sample quantity
of 0,02 l (corresponds to the supplied measuring cups).
Grinding the sample and filling the measurement cell
NOTICE The parts of the measurement cell cannot be exchanged by mistake.
This does not apply to older instruments. Attention must be paid that these parts are
not exchanged. This can lead to incorrect measurements! The parts of the
measurement cell are numbered. The upper and the lower part are marked with the
same number.

NOTICE Remove moist grist from the measurement cell immediately after the measurement!
Clean the hand mill or laboratory mill, measurement cell and the spindle after each
measurement, see chapter 6.1.
7.3.1 Grinding with the hand mill
NOTICE The products oats, spelt, maize (corn) and sunflower seeds must not be grinded with
the hand mill!
Substantiation:
Grinding these products requires a lot of force, especially for very dry products (< 14 %
moisture) and for very moist products (> 24 % moist
ure). Products with a high
husk/glume content (e.g. oats, spelt) have problems with the grains being drawn into
the knife disc.
The grinding of maize (corn) and sunflower seeds takes longer than that of cereals,
because the smooth surface of the grains means that the knife disc hardly finds any
points of attack. In addition, the cleaning effort is enormous.
Figure 3: Hand mill and lower part of measurement cell
In case of the product wheat, durum, rye, barley or triticale fill the measuring cup 0.02 l brimfully by
shaking.
In case of 00 rapeseed fill the measuring cup "Raps" (Rapeseed) brimfully by shaking.
Place the hand mill on the lower part of the measurement cell. The screw cap of the hand mill cover must
be firmly tightened. The measuring cup is poured into the hand mill. The crank handle of the hand mill is
turned clockwise, until no sensible resistance can be felt (approx. 15 s). The coarse meal falls directly into
the measurement cell.
The hand mill is removed, the upper part of the measurement cell is placed onto the spindle and turned
up to the limit stop.
Should it not be possible to grind the sample properly, this might be due to worn knifes of the hand mill
or to a faulty crank – Replacement see chapter 9.2.1 and 9.2.2.
Should the replacement not lead to an improvement, then the hand mill must be returned to the
manufacturer (Pfeuffer GmbH) or to an authorized dealer for repair.

In case of the product wheat, durum, rye, barley, triticale, oats or sunflower seeds, fill the measuring
cup 0.02 l brimfully by strongly shaking.
In case of 00 rapeseed fill the measuring cup "Raps" (Rapeseed) brimfully by shaking.
For maize (corn) see chapter .
Place the measurement cell lower part under the mill outlet. Slide the outlet onto the measurement cell
by turning the outlet by about 20° to the left and then push it downwards. The sealing rubber must be
placed on the measurement cell edge. The integrated spindle protection prevents the spindle from being
soiled.
Adjust the lateral lever according to the used sample type: Top position for moist maize (corn), sunflower
seeds, oats. Lower position for all other products.
Switch on mill and wait until the mill has started. Fill in the measuring cup and press the dosage button
on the filling funnel slowly downwards until the filling funnel is completely emptied. Let the mill run for
about 10 seconds until all grains are grind. Open the grinding chamber and clean the outlet with a brush.
Push the outlet upwards and fix it by short turning it upwards to the right.
Remove the lower part of the measurement cell and place it on the measurement instrument. Insert the
upper part of the measurement cell as far as it will go to the limit stop.
