Sanitary Filter Receiver Handles Stringent Foot Applications
Coperion K-Tron will introduce a new sanitary filter receiver (SFR) at the Powder Show in Rosemont, Ill., May 6-8. The SFR provides automatic separation of product material from the convey air for vacuum and pressure conveying sanitary applications in batch and continuous processes. The SFR was designed for stringent food applications requiring quick clean-out and to reduce food contaminants and/or the cross contamination of allergens.
The tool-less side entry access door allows for safe and easy cleaning of the unit and simple access to the filter media for fast changeover. The access door and tube sheet are integrated on a single hinge with removable tube filter assemblies. The unique material entry design on the top of the receiver reduces can velocity concerns. The unit also features an integral 70 degree hopper, mounting legs and pressure differential indicator. The SFR is designed to meet FDA, EHEDG, ATEX standards and can easily be adapted for NFPA standards.
The SFR is available in a 914 mm (36-inch) and a 1,219 mm (48-inch) diameter unit. It’s constructed from DIN 1.4301 [AISI 304] stainless steel with highly polished P150 grit Ra 0.8 surface on both the interior and exterior of the unit – commonly used in food processing and dairy equipment. All product contact welds are continuous ground flush and polished to 1.65 Ra (80 grit).
The filter tube sheets include filters made from spunbond polyester with an ePTFE membrane which is FDA acceptable. The filters are cleaned by sequential pulses of compressed air from a removable, locally mounted accumulator. Pulsing intervals are adjusted via an DIN 1.4301 (AISI 304) stainless steel IP66 (NEMA 4X) timer panel to ensure optimal cleaning.
