What is the In-Line Sifter?

Though In-line sifting was not invented by Great Western, our In-Line sifters are unique. They are sifters engineered to work under pressure rather than a pressure vessel adapted to act like a sifter. Because Great Western put the priority in sifting, our In-Line sifters incorporate the features engineers, sanitarians, maintenance personnel, and operators have come to expect in any reliable gravity flow sifter.

The Great Western In-Line Tru-Balance Sifter allows direct insertion into a vacuum or pressure pneumatic conveying line and is intended as a quality assurance tool for removing a small amount of oversized impurities from the product. Placed in pneumatic unloading or transfer systems, the In-Line Tru-Balance eliminates equipment such as cyclone receivers, airlocks, receiving hoppers, and blowers. All of which would be required if a standard (atmospheric pressure) sifter were utilized. All product contact surfaces are fabricated of stainless steel, which ensures compliance with the most stringent of sanitation standards.

The new Quality Assurance (QA) Series of In-Line sifters, the QA24, QA30, QA36, and QA46 replace the previous models 611 and 621.
