Insulated Quick-Clean Centri-Sifter
The Insulated Quick-Clean Centri-Sifter is a high-capacity centrifugal screener whose insulated jacket maintains the temperature of hot or cold materials as they are being sifted while keeping the machine’s exterior skin closer to room temperature to ensure personnel safety. Its three-bearing shaft cantilevers to enable the rapid removal of internal components. The external roller bearings located at the motor end of the shaft and on a sliding cover at the discharge end provide for maximum support and enable vibration-free operation. Clean-in-place spray balls permit rapid sanitizing using steam or cleaning solutions without the removal of internal components.

Centri-Sifter MO
The Centri-Sifter MO is a medium-capacity centrifugal screener with a cantilevered shaft that has two externally mounted bearings between the screening chamber and the motor drive. This design allows all internals to slide freely from the shaft end for cleaning, screen changes, and inspections. The screener has wide spacing between the bearings, a large-diameter shaft, and a flexible shaft coupling. These features prevent vibration, even at high speeds under heavy, imbalanced loads. The unit is suitable for food, dairy, and pharmaceutical applications requiring thorough wash-down, as well as other applications involving frequent screen changes and inspections or runs of multiple materials where cross-contamination is an issue. Configurations are available for continuous in-line operation with dilute-phase pneumatic conveying, as well as for gravity-fed applications.

Centri-Sifter twin centrifugal screener
The Centri-Sifter twin ultra-high-capacity centrifugal screener provides the performance of two individual high-capacity screeners, but with a smaller footprint. It handles either dry or moist bulk-solid materials, which are gravity-fed through a splitter that evenly divides the incoming flow into two horizontally oriented cylindrical screening chambers operating in parallel. A shaft in each screening chamber rotates a helical paddle assembly that accelerates the radial movement of particles against the screen. Particles of the desired size pass through apertures in the screens and fall into a cone-shaped discharge chute, while oversized particles are propelled through the open end of the cylinders and ejected via a discharge spout. Each screening chamber features a sliding end cover and a three-bearing shaft that cantilevers for quick removal of internal components and rapid sanitizing. External roller bearings are located at the motor end of the shaft and on a sliding cover at the discharge end for maximum support and vibration-free operation.

Granulizing-Drying System
This granulizing-drying system consists of a centrifugal screener, a spheroidizer, a circulating fluid-bed dryer, and a vibratory screener. Non-flowing moist solids that have been discharged from cartridge and vacuum filters, filter presses, mixers or other equipment are converted into uniform, compact, dry, de-dusted, free-flowing granules that can be stored, shipped, packaged or put through secondary processing. Its Centri-Sifter centrifugal screener uses rotating helical paddles to break up lumps and drive non-flowing materials through apertures in a horizontal cylinder, thereby continuously producing moist pellets at high rates. Binder powder may be applied before the materials enter the unit or with internal spray nozzles. The fluid-bed dryer vibrates and dries particles on a perforated screen within a rising column of heated air on a first-in/first-out basis. Dried particles are discharged into a vibratory screener that uses an upper screening deck to gently remove oversized particles and a lower deck that removes undersized dust particles for re-processing. This screener operates on a batch or continuous basis. The system’s equipment meets industrial, 3A, FDA, USDA, BISSC and other sanitary standards.

Centri-Sifter MO-SS centrifugal screener
The Centri-Sifter MO-SS centrifugal screener has a hinged end cover and a three-bearing cantilevered shaft to ease internal component removal. External roller bearings are located at the motor end of the shaft and on a hinged cover at the discharge end for maximum support and vibration-free operation. When the end cover is opened, the shaft becomes a cantilever supported by a third externally mounted roller bearing located between the motor-end bearing and the material feed point. This design allows internal components to slide freely from the opposite shaft end for a thorough washdown. It uses rotating helical paddles to propel gravity-fed materials against the chamber’s internal screen, and the resulting centrifugal force pushes materials through apertures, where they are separated into discharge housing for inspection or ejected through a spout as trash. The screener is constructed of stainless steel that is finished to 3-A Sanitary Standards (3-A), U.S. Food and Drug Admin-istration (FDA) regulations, Baking Industry Sanitation Standards Committee (BISSC) guidelines, and other standards imposed on food, dairy and pharmaceutical applications. It is suitable for general chemical applications that require frequent screen changes and inspections or for applications that involve multiple materials where cross-contamination may be a concern. 

Flo-Thru sifter
The low-profile Flo-Thru sifter features a gap-free screen frame with quick-disconnect clamps and a crevice-free interior finished to cGMP, 3-A, USDA and FDA standards. This finish allows a rapid, thorough washdown. Its design significantly reduces minimum height requirements with two unbalanced-weight gyratory motors mounted on opposing exterior sidewalls of the unit, rather than the usual single motor positioned beneath the screening chamber. The unit can be disassembled with no tools for rapid sanitizing and is intended to separate oversize particles as small as 38 µm (400 mesh) from dry bulk materials or solids-laden slurries. The wire mesh screening material is offered in Types 304, 316 and “magnetic” 400-series stainless steel that can be captured by a downstream magnet if broken. The sifter is offered in diameters of 24-in., 30-in., 40-in., 48-in. and 60-in. It can be equipped with either single or twin imbalanced-weight gyratory motors, and furnished with a dust-tight cover.

Kason 3-in-1 System
Designed to regulate the flow of material into the screener, the Kason 3-in-1 System combines a Vibroscreen vibratory screener, a batch hopper and an integral feed control device. Consisting of a circular disc positioned below the flexible connector at the screener’s inlet, the feed control device is perpendicular to the flow of material. The disc’s diameter is smaller than the inside diameter of the inlet. This forms an annular gap through which materials pass. The flow of material remains uniform as the disc vibrates with the screener lid to which it is affixed. Achieving variable feed rates is possible using interchangeable discs available in a range of diameters. Suspended by springs, the screening assembly freely vibrates, minimizes power consumption, and prevents vibration transmission to the floor. Beneath the assembly is an imbalanced-weight, gyratory motor that creates multi-plane inertial vibration for the purpose of controlling the flow path of material on screen surfaces, and maximizing the rate at which material passes through the screen. Intended for applications that require screening in batches, screeners are available with the feed control device range in diameters from 18 to 40 in. Offered with single or multiple screening decks, they separate particles in one to five predetermined sizes, from 2-in. to 500 mesh. The screeners are constructed of stainless steel to 3-A, cGMP, USDA, FDA or industrial standards.

Vibroscreen Ultra-Sanitary Double-Deck Screener
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. The new screener dramatically reduces the possibility of contamination due to bacteria growth, while improving sanitizing efficiency, making it suitable for pharmaceutical, food and dairy applications, as well as chemical applications where cross-contamination is a concern, according to the company.

Vibroscreen Sanitary Batch Sifter
Meeting cGMP, 3-A, USDA and FDA standards, the Vibroscreen Sanitary Batch sifter can be disassembled without tools for rapid sanitizing. It is intended to scalp oversize particles as small as 38 µm (400 mesh) from dry bulk materials or solids-laden slurries. The screen frame’s interlocking flange fully envelops the support ring of the screen, eliminating the gap between the screen ring and frame wall. 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. The sifters are offered in diameters of 18, 24 and 30 in. (450, 610 and 750 mm), and can be equipped with either single or twin imbalanced-weight gyratory motors.
