Grease Shield Features

3 Stage Grease Cleansing Process

Stage 1 – Food removal

As water enters the grease recovery unit, a screen separates solids and a de-watering auger transfers them to a collection drawer.

Stage 2 – FOG removal

Five co-operating baffles and a reverse direction flow force the effluent to travel twice the length of the unit, forcing the waste water into contact with the FOG removal drum. FOG’s are picked up via a scraper blade and transferred into a container for disposal.

Stage 3 – Self Cleaning operation

The Grease Shield grease recovery unit has an automatic self-cleaning feature whereby the contents of the unit are periodically cycled through the inlet screen to filter solids that may have accumulated. A spray device washes the mesh of the inlet filter screens to ensure their continued efficient operation. The Grease Shield can remove FOGs down to a level of 100 parts per million (ppm).

Easy Maintenance

The only operator intervention necessary is the removal of the food waste tray and disposal of the contents to a bin and the removal of the FOG collection container and the transfer of its contents to a waste cooking oil container.

Collected FOG from a the grease recovery unit has very minimal water content and is suitable for use in the production of Bio-Diesel.

Long intervals between deep cleans

The Grease Shield will require yearly or half yearly deep cleaning and replacement of wiper blades to ensure efficient FOG removal.
