1Introduction
1.1 Designated use
The GRANOLYSER is an NIR analyzer (NIR = near infrared) for whole grain samples, such as various cereal
types, leguminous crops (pulses) and oil seeds.
The sample is filled into the instrument. The measurement is started and settings are made using the
integrated touchscreen.
The analysis parameters are defined visually. An integrated weighing system is used to determine the bulk
density (Variant HL). Various parameters are defined depending on the selected product:
•Moisture, protein, sedimentation index (Sedi), gluten, oil content, starch
•Variant HL: Bulk density = mass per hectoliter [kg/hl]
The GRANOLYSER has two USB interfaces and one RJ45 interface for outputting and processing the
measurement results.
The GRANOLYSER is designed as a portable instrument with a mains plug for indoor use (laboratory
environment).
Private use of the GRANOLYSER is not allowed.
NOTICE The GRANOLYSER is exclusively intended for the indicated purpose.
Any other use beyond this definition, or conversion of the GRANOLYSER without written
consultation with Pfeuffer GmbH, is regarded as not in accordance with the designated
use.
Pfeuffer GmbH will not be liable for any damage resulting from this! The risk is the
responsibility of the owner alone.
The GRANOLYSER is only allowed to be taken into operation if it can be ensured that all
safety instruments are functioning.
The GRANOLYSER is not suitable for measuring liquid and sticky products, as well as
fine flours.
The GRANOLYSER is not intended for operation in potentially explosive atmospheres.
The samples to be used in accordance with the designated use of the GRANOLYSER are
obtained by the owner.
Correct treatment of these materials and the associated risks
are exclusively the
responsibility of the owner.
The owner must provide information about dangers and disposal.
The designated use also includes complying with the operating instructions as well as the maintenance
and servicing conditions as defined in these operating instructions.
These operating instructions do not release the owner from the responsibility to develop and apply, or
have applied, health and/or safety regulations appropriate for the requirements of the overall system,
and to monitor compliance with the same.

6.2 Sequence of functions
The GRANOLYSER is an NIR analyzer for whole grain samples such as various cereal types, leguminous crops
and oil seeds. Switch on the GRANOLYSER using the main switch (position I). The operating system starts.
Following the warmup phase, fill the sample contained in the supplied 600 ml measuring beaker into the
filling funnel. Select a product on the display and start the measuring procedure. The electric motor
connected to the conveyor wheel is started.
A halogen lamp with controlled light intensity illuminates the sample. The GRANOLYSER uses the reflected
constituents in the range from 950 to 1540 nm (NIR) to detect the presence of a sample.
The conveyor wheel ensures the most homogeneous possible density during the measurement. By even
rotation, the material is continuously transported past the detector, and the reflection from the sample
in the NIR range is measured. The spectra recorded by the detector are processed in the evaluation
electronics. The measurement result is shown on the display.
In the apparatus GRANOLYSER HL, the bulk density [kg/hl] (hectoliter weight) is also determined by means
of an integrated weighing instrument for all products
For precise information about operation, refer to chapter 7.
6.3 Reference methods for calibration
Pfeuffer GmbH uses the following reference measures, amongst others:
Parameters
Reference method
Moisture
Dry cabinet (cereal, maize, leguminous crops and oil seeds)
Protein
Kjeldahl or Dumas process
Conversion factors 5.7 (wheat, durum, spelt, rye) or
6.25 (barley, triticale, oats, maize, soya beans, peas)
Oil
Soxhlet extraction or NMR – nuclear magnetic resonance spectroscopy
Gluten
Mechanical process for determining the wet gluten
Sedimentation index
Zeleny test
Starch
Polarimetric determination
Bulk density
(hectoliter weight)
EEC4bulk density
NOTICE DIN EN ISO 7971-3 (Cereals – Determination of bulk density, Part 3 – Routine method)
specifies various equations for the analysis, and these are applied by Pfeuffer GmbH.
For durum, triticale and spelt the wheat equation is used.
The bulk density (hectoliter weight) result of the GRANOLYSER HL
•is based on the actual moisture result of the sample, and is not adjusted to a lower
moisture value (9 % to 14 %).
•does not equal the EEC bulk density according to directive 71/347/EWG and may
not be used in legal transactions.
