Ultra-sanitary batch sifter FDA-, USDA-, cGMP-compliant

January 23, 2006
The new FDA-, USDA- and cGMP-compliant batch sifter meets the most stringent food, dairy and pharmaceutical standards. The dust-tight sifter has a stainless steel housing, motor and stand, tri-clover inlet and outlet flanges, vertical quick-disconnect clamps and continuously ground and polished welds. The unit features a gap-free flange arrangement where the screen support ring interlocks with the upper and lower frames of the screener. The design allows the wire mesh of the screen to fully extend to the interior walls of the frame, eliminating the gap between the screen ring and frame wall of conventional screeners where material would otherwise collect. The unit scalps oversize particles down to 38 microns (400 mesh) from dry bulk powders or solids-laden slurries, and can be disassembled with no tools for rapid sanitizing. Screens are mounted to support rings using FDA-approved epoxy and sealed using FDA-approved gasket material, and can be provided with a mesh-tolerance certificate. The wire mesh screening material is offered in 304, 316 and magnetic 400-series stainless steel that, if broken, can be captured by a downstream magnet.
