Used Cooking Oil

Used Cooking Oil Recycling and Reuse with Flottweg Technology

Recycled and reconditioned used cooking oils are raw materials for the manufacture of biodiesel and technical greases.

Used cooking oils such as fryer oil or the contents of grease separators often contain significant quantities of undesired foreign matter.  For the manufacture of biodiesel or technical greases, these materials must be separated from used cooking oil and grease separator contents.

How is used cooking oil processed? - The Recycling Process

For processing, the used cooking oil or grease separator contents are heated to the required processing temperature and fed into the three-phase centrifuge.

The Flottweg Tricanter® then separates water, oil, and solid particles from one another in a single step. Thanks to its robust design, the centrifuge can separate solid particles of different sizes and in different quantities with no problems.
