Continuous Drum Filter
Efficiently separate particles from frying oil
In the frying process, the oil must be continuously filtered for removal of small particles minimizing build-up and oil breakdown in the fryer. The PPM Technologies Continuous Fat Filter filters the oil in full flow so oil passes the filter at least once per minute. The efficiency of the filter system in optimized by minimizing the amount of oil in the filter.
The PPM Technologies Continuous Fat Filter (CFF) forms a filter plate using stainless steel perforated screens. The filter opening is application dependent due to filtering to the smallest particle. A variety of sizes are available from a diameter perforation of 1,000 microns to a slot perforation of 1,1 x 16 mm and sizes up to 15,000 l/min (4,000 gpm).
The perforated screens form into a rotating drum through which the oil passes. The drum slowly rotates and all particles and debris are collected on the outside of the drum. The debris is then removed via stainless steel scrapers with replaceable tips. A waste auger or box collects the debris.
In order to minimize the oil volume inside the filter drum, the unit has a displacement body. All floating particles or particles on the inside of the drum are removed by a Teflon® scraper.
