METHOD FOR SEPARATING AND RECOVERING USED CLAY

摘要

PROBLEM TO BE SOLVED: To provide a method for separating and recovering an oil and fat and an inorganic adsorbent by centrifuging the inorganic adsorbent used for a decoloring purification treatment and mostly disposed of just after the decoloring purification treatment. SOLUTION: The method for separating and recovering the oil and fat and the inorganic adsorbent comprises centrifuging a mixed liquid of the oil and fat with the inorganic adsorbent just after the decoloring purification treatment and continuously separating and recovering the oil and fat from the inorganic adsorbent. The mixed liquid of the oil and fat with the inorganic adsorbent just after the decoloring purification treatment is cooled to 60-90 deg.C and then continuously centrifuged by 6,000-12,000 centrifugal effects at 1,000-6,000 L/h throughput.
