A new sanitary clean-in-place Vibroscreen double-deck screener from Kason Corp. removes oversize and undersize particles from on-size chemicals, minerals, plastics, foods, dairy products, pharmaceuticals and other bulk materials.
The 40-inch (1016-mm) diameter unit contains two horizontally mounted screens in a cylindrical housing supported on a circular base by rugged springs. An imbalanced weight gyratory motor affixed to the housing imparts vibration, causing oversize particles to travel across the coarse upper screen and exit through an upper discharge spout at the screen's periphery. On-size particles falling onto the lower screen are discharged through a center discharge spout, as undersize material flows through the screen, onto a chute and through a lower discharge spout.
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. An air-lift device is available to pneumatically raise any of the screen frames, enabling one operator to rapidly perform what was previously a two-person task.
The unit is also offered in diameters from 18 inches to 100 inches (460 mm to 2540 mm), and can operate on a batch or continuous basis, screening several pounds/kilograms to 70 tons per hour.
