Micromill for characterisation of the milling value of wheat grains

Identification

Key words Micromill, prediction, flour yield, characterisation, dry fractionation process, wheat grain
Latest version 2012/11/27
Completed by INRA - IATE

How does it work?

Primary objective to predict the milling value (i.e. flour yield) of several kinds of wheat with a sample of only around 500g using a micromill prototype.
Working principle This method relies on the study of the milling value of wheat grains and of the chemical composition and the rheological properties of the flour products.

A special processing diagram has been established with a micromill prototype in order to reproduce the results obtained with industrial mill and diagram (4).

Tests have been conducted on more than 80 different wheat samples (differences in genetics, geographical origin and year of crop). The results for flour yields and for bran purity can be used as prediction models and decision tool for cereal industry searching for the best wheat milling value (1-3, 5).

Additional effects The special processing diagram leads to a reduced percentage of damaged starch.

The flour obtained with this micromill could be used for baking tests.

Important process parameters Processing diagram

Results could be used to compare the behaviour of different wheat samples and are reliable thanks to the industrial diagram. However relative quantities rather than absolute values have to be considered.

Important product parameters

What can it be used for?

Products Common wheat (soft & hard) (Triticum aestivum)
Operations Milling and sieving

baking tests

Solutions for short comings Instruments for measuring rheological properties of flour

Wheat starch quality

What can it NOT be used for?

Products Any other products than common wheat durum wheat (not tested yet)
Operations Any other operation than separation
Other limitations The absolute milling values of wheat samples that are obtained with this method are not so interesting by themselves and can’t be compared to the conventional values.
Risks or hazards No known hazard

Implementation

Maturity The technology is protected through a registered patent (french territory).

Today, 2 prototypes have been constructed. The commercial version is coming soon (mid 2014). The flour obtained with this micromill could be used for baking tests
