A sanitary clean-in-place vibroscreen double-deck Screener from Kason removes oversize and undersize particles from on-size powder and bulk food and dairy products. The screener is equipped with quick-disconnect clamps between each screen frame, providing rapid interior access for inspection and screen changes. An integral clean-in-place spray wash system employs spray nozzles strategically placed to emit cleaning solutions, rinsing solutions and/or steam for sanitizing the interior of the screening chambers without the need to open or otherwise disassemble the unit. Constructed of stainless steel with ground and polished welds, it meets 3-A, FDA and BISSC sanitary standards, as well as UL, ATEX, CSA and CE electrical standards.
