Sights set on product safety

Uzwil, July 23, 2008 - Three Buhler innovations support the grain milling industry in its efforts to improve product safety.

In the food processing industry, one notion clearly dominates the current discussion: product safety. Sensitized by news of food contamination, consumers worldwide have become more alert and de-manding. The changes in customer needs are forcing the food industry to take action to improve prod-uct safety. With three innovations, Buhler is helping flour and semolina producers ensure the safety of their products.

C-frame for final sifting

“C” stands for “control.” The new C-frames from the Buhler NOVAPUR product family are applied in the final flour and semolina sifting stage before packing or bulk loadout. The developers at Buhler have redesigned the Cframe from scratch. A sophisticated frame geometry, paired with the PUR mate-rial now used and the special stainless steel frame inserts with gluedon sieve covers, satisfy the most rigorous food sanitation requirements. The larger channels and parallel product streams of the sifter allow final checking in a highly restricted space and with maximum throughput, even when using small mesh widths.

MYRB improves final checking

Together with the innovative MYRB unit, Buhler has substantially improved final quality control. The MYRB is a new-generation near-infrared (NIR) online device. Final checking by infrared reflection is now performed by spectrometer on the basis of diode array technology. With more than ten times the resolution of the predecessor model, flour and semolina are checked for their mineral, water, and pro-tein contents as well as for the starch condition and water absorption capacity. The MYRB can be applied for monitoring the end product on the basis of a predefined tolerance band or within a closed control loop for automatic control of feeders. As an option, it is possible to add a camera to the MYRB, which checks the end products for color and specks.

The right blend every time

As a third innovation, Buhler has rolled out the new DFML-Sani mixer. Design adjustments were made to the standard mixer which make it easier to clean the new Sani mixer and therefore improve its ver-satility. The new DFML-Sani does not have any joints, cross-bars, or nooks and crannies.

The screw heads are sealed, and the components in contact with the product are made of stainless steel. The new DFML-Sani mixer satisfies the stringent requirements for food-compliant machine de-sign according to the EHEDG directive. The new mixer meets the same performance standards as the standard model. Its reduced cleaning requirement increases process versatility in applications involv-ing different products. Undesirable cross-contamination is no longer possible.

Buhler is a global leader in the field of process engineering, especially technologies for producing foods and engineering materials. Buhler sells into over 140 countries and has some 6900 employees worldwide. In fiscal 2007, the Group generated sales of CHF 1770 million.
