A compact Haarslev Fat Filtrator removes solids (fines) present in the fatty sludge from the screw presses in your operation, and is often installed upstream from a decanter centrifuge that separates the tallow still further.
The flow of fatty sludge passes through a vibrating screen with a mesh size of 0.7–1.0 mm. The fat passes through, and any solids remain on top. The combination of the angled position and the vibration of the screen transports the solids to the outlet.
You can use screen meshes with particular size holes to deal with fat flows with different specifications.
