Micro Air

Roto-Pulse
The automatic, incrementally rotating Roto-Pulse uniformly cleans 30–40% more filter surface than conventional reverse-pulse systems. The additional area of clean media means a lower air-to-cloth ratio requirement, lower grain loading, more-efficient filter cleaning, and longer filter life. The system operates by pulsing air into a specially designed stainless steel perforated tube. As the air enters, the tube rotates a specified number of degrees, distributing the pulse of air across the length of the cartridge’s inside surface and dislodging clogged dirt from the outside of the cartridge. The number of increments per revolution can be adjusted, as can the time between pulses, for maximum flexibility. It runs up to 15 dBA quieter and uses less compressed air than reverse-pulse systems.

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. 

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 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.
