French Oil Settling Tanks are supplied with one to three settling chambers for separating foots (solids) from the oil, depending on the size of tank required for a particular oilseed processing application.
For smaller capacity processing plants, oil settling tanks with one chamber are supplied. The oil, with foots, enters the tank chamber for a minimum of 1 hour, during which most of the foots in the oil settle to the bottom of the chamber. The chamber has two malleable iron chains with a series of paddle scrappers that slowly rotate along the bottom of the chamber to collect the settled foots, lift them up, pull them over a wedgewire screen that serves as a non-clogging drainboard, then drop them into a foots discharge conveyor that returns them to the conditioner or screw press feed system. The settled oil overflows from the chamber into a side holding chamber and is pumped from the tank.
Larger capacity plants are supplied with larger oil settling tanks with two to three chambers. On these tanks, when the first chamber fills with oil, the oil overflows into a second chamber, and in our larger tanks into a third chamber. Each of these chambers has two malleable iron chains with a series of paddle scrappers that slowly rotate along the bottom of the chamber to pick up the foots and convey them to the foots discharge conveyor. The amount of foots in the oil is reduced in each chamber until the oil flows to the side holding chamber and is pumped from the tank.
