PeriTec Wheat Debranning System
THE FIELD IN DEBRANNING TECHNOLOGY
Milling System of the 21st Century
PeriTec is a unique process, developed by Satake, which can be
utilised in the cereal milling industry for applications such as debranning wheat,
dehulling barley and degerming maize.
The PeriTec process sequentially removes the outer kernel bran layers prior to milling or
subsequent processing, which optimises the yield and reduces the amount of bran
contamination in the finished product.
The equipment used in the PeriTec process is able to sequentially
strip the bran layers, giving the degree of control that the commercial flour miller
demands. Within one machine bran removal rates can be adjusted from a few
percent in order to heavy scourer the
outside of the grain to 10 - 12 % required for
some specialist processes.
many years of experience shows that that for the
majority of mills, the optimum bran removal
for high quality bread making flour is in the
region of 6 - 6.5% and for durum semolina milling 8 - 8.5%.
advantage of the PeriTec
System is its flexibility. The ability to adjust the
amount of bran removed is ideal for mills required to produce a range of
products such as wholemeals, browns and white flours. When producing wholemeal
flours, the abrasion chamber can be by-passed
and only the friction chamber used to heavy scour.
When the mill produces white flour, the whole machine is used and higher optimum
debranning rates are achieved.
The process is fully automated and features a control system that adjusts for
variations in the nature of the raw product being fed into the system.
PeriTec Debranning Process also has important
applications in starch and ethanol product systems, where the
removal of bran prior to milling can substantially
improve the efficiency and performance of
PeriTec vs. Conventional Flour Milling
During the 20th century the conventional wheat milling system became dominant for the
production of bread flour and high extraction white flour. The PeriTec System removes the
wheat bran layers, apart from that which is in the crease, before milling. Hence, there is
less bran to remove so the milling 'break' system can be shortened and a greater amount of
semolina and middlings is produced with a better product colour.
Mill flow diagrams are less complex as there is less bran, a
potential contaminant of white flour, to be processed in the mill.
A conventional milling system loses most of the nutritionally rich aleurone cell layer, as
it does not effectively strip it from the inside of flakes of bran. The PeriTec system
allows substantially more of the aleurone cells to be released.
The removal of the peripheral bran, prior to milling, results in finished products that
are brighter in colour and free of bran specks whilst retaining more of the nutritional
components of wheat than a conventional milling system.
The process is exceptionally effective when used in durum semolina mills as it allows a
large amount of coarse, clean, semolina to be released early in the milling system. The
semolina mill diagram is less complex than a conventional semolina mill. It can also be
utilised in starch and gluten production plants. The reduction in the risk of bran
contamination reduces the potential problem of undesirably high fibre content in the flour
going to the starch extraction plant.
results from several UK mills prove that the PeriTec
System improves the Hagberg Falling Number of wheat. This allows the miller to
avoid problems in a year of low Hagberg values, or to take advantage
of purchasing lower cost low Hagberg wheats and then improving them in the
mill using the PeriTec Process.
