  • Adsorbent filtration system for treating used cooking oil or fat in frying operations
    Patent number: 6368648
    Abstract: A process for treating used cooking oil or fat by passing the used cooking oil or fat from a used cooking oil or fat source to a holding vessel, and contacting the used cooking oil or fat with a predetermined amount of purifying material upon accumulation of a first predetermined amount of the oil or fat in the holding vessel.
