Suitable for pharmaceutical, food and dairy applications, as well as chemical applications where cross-contamination is a concern, the Vibroscreen ultra-sanitary, double-deck screener for scalping, de-dusting and dewatering of contamination-sensitive materials meets cGMP, 3-A, USDA and FDA standards. The unit features gap-free screen frames, quick-release‘U’ clamps, radius corners, a domed lid, an Air-Lift device to raise the frames, continuous ground and polished welds, a gap-free and crevice-free interior and a washable underside. The external, interlocking flange configuration of the screen frame fully envelops the support ring of the screen, allowing the screen’s wire mesh to extend to the interior walls of the frame. The design eliminates the gap between the screen ring and frame wall of conventional screeners, eliminating areas where material would otherwise collect. 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. The screener can be equipped with a clean-in-place spray wash system, and it can be designed to operate under a blanket of an inert gas.
