The Russell Compact Sieve® can be combined with the Russell Vibrasonic Deblinding System for the high-performance screening of fatty powders. Vibrasonic® Deblinding System removes foreign contaminants with minimal blockage to the mesh screen.
Without the system in place, mesh apertures can become blocked, resulting in a significantly reduced flow rate. With the Vibrasonics, the mesh apertures remain clear, allowing for the product to flow through the sieve at more than double the flow rate.
Case study: buttermilk powder
Similar to milk powder, buttermilk powder is processed using spray drying. It has a clean, dairy flavour, with excellent solubility and good emulsifying properties. This cream powder contains a higher fat content than normal milk powder, making it thicker with higher levels of moisture.
Higher fat content can be a problem when sieving buttermilk. As a heavier powder, it is prone to blockages and causes substantial mesh blinding, which reduces overall capacity, slowing production rates. Blinding results from particles plugging into the open apertures of the screen mesh which slows down overflowing material from falling through the mesh screen.
The Russell Compact Sieve offers high-capacity safety screening of powders and liquids, removing oversize contamination while ensuring correct product quality. The Russell Compact Sieve was chosen as the machine is best suited to this process due to its quick and easy operation. Meanwhile, its compact size ensured it would fit neatly into an existing production line.
The Russell Vibrasonic Deblinding System helps to sieve powders on finer meshes, while offering greater accuracy and providing precise sieving down to 20µm. Ultrasonic sieving helps improve the quality of your final product as well as the value.
Russell Finex research and test facilities provide a valuable opportunity for customers to test Russell sieving and filtration equipment while providing complete peace of mind that the machinery chosen is right for you.
