Siebreinigungshilfen erhöhen Leistungen, reduzieren Instandhaltungsarbeiten

Kason bietet eine Vielfalt an Einrichtungen die Siebverstopfungen eliminieren und dadurch die Durchsatzleistung erhöhen. Diese Einrichtungen verringern den Abstand zwischen den rotierenden Paddeln und dem zylindrischen Siebgewebe, ohne in Kontakt mit ihnen zu kommen oder sie abzureiben. Ein verringerter Abstand zwischen dem rotierenden Bestandteil und der Oberfläche des Siebgewebes verbessert die Durchsatzleistungen bei Anwendungen, wo die Granulometrie des zu siebenden Produktes der des Gutproduktes sehr ähnelt, und erhöht dadurch die Durchsätze.

 
Gummiwischblätter sind für faserförmige Stoffen eingesetzt, die sich sonst in Börsten verfangen oder an Sägekanten hängenbleiben würden. Gummiwischblätter erlauben das Überkorn unter die rotierendn Paddel zu passieren und sind auch bei der Siebung von Flüssigkeiten/Feststoffen nutzbar.

 
Feine Maschen, die vielleicht mit mechanischen Siebreinigungshilfen beschädigt oder abgerieben wären, werden durch eingebauten Luftbürsten gereinigt. Die Luft wird durch das Ende der hohlen Antriebswelle eingeblasen und durch mehrere Luftdüsen ausgeblasen und reinigen dabei die Sieboberfläche.

 
Die Börsten sind biegsam und werden zirka 1.6-3.2 mm von der Sieboberfläche abgehalten und das Gutprodukt fließt problemlos durch die Maschen ohne diese selbst zu beschädigen.

Bag Dump Stations

CENTRI-SIFTER^® centrifugal screeners are available with integral bag dump stations, with or without dust collectors. Normally configured for installation at mezzanine level, they afford a sufficiently low deck height for operators to dump sacks and other containers, while allowing material to discharge into conveyors, process equipment or storage vessels below.

Bag dump stations with optional dust hoods draw ambient air and dust from dumping activities onto the exterior of two cartridge filters that derive vacuum from a top-mounted exhaust fan. Dust accumulated on the filter's exterior surfaces is dislodged by overcoming continuous negative pressure within the cartridge filters, with positive pressure introduced in short blasts on a timed cycle by pulse jet nozzles. Dislodged material falls into the screener while instant resumption of negative pressure collects any dust generated by the filter cleansing operation.

The Bag Dump Station components are constructed of stainless steel and finished to industrial, food, dairy and pharmaceutical standards.

Kason twin CENTRI-SIFTER^® configurations are designed for applications requiring greater capacity than a single high-capacity unit can provide. These duplex units are equipped with a splitter to evenly divide the flow of incoming material, regardless of feed rate.

Integral feeders eliminate the need for separate units while reducing overhead space and length requirements. Powered by its own variable speed motor and drive, the unit offers independent control of material feed rates—regulated by the machine operator or from the control panel—prolonging screen life by preventing overloads due to surging.

CENTRI-SIFTER^® centrifugal screeners for Clean-In-Place (CIP) applications are available with quick-disconnect fittings, ground/polished welds and construction to rated for high pressures and temperatures. Internal nozzles can spray cleaning and rinsing solutions to sterilize the screener's interior hands-free.

All CENTRI-SIFTER^® centrifugal screeners are available designed, constructed and finished to industrial, food, dairy, and pharmaceutical standards including FDA, 3-A, BISSC, EEC and others. Sanitary screeners generally offer one or more of the following features:

• Clean-In-Place (CIP) spray nozzles
• Radius corners and ground/polished welds
• Quick-release fittings
• Three-bearing cantilevered shaft for quick removal of internals
• Thread-free internals and tool-free disassembly for fast, thorough washdown (shown)

CENTRI-SIFTER^® centrifugal screeners for pharmaceutical applications are available with the options listed above, and in miniature sizes (shown) ideal for screening, scalping, de-lumping and dewatering small batches of pharmaceutical powders. In less than one minute and with no tools, the unit's end plate, cylindrical screen and shaft-mounted paddle assembly can be removed, providing access to sanitize all material contact surfaces. The unit is constructed of stainless steel with all continuous welds ground and polished to FDA as well as 3A, BISSC and other standards.

All CENTRI-SIFTER^® models are available in belt drive(top) and direct drive(bottom) configurations.
