Structure including rice hull ash and reinforcing binder for adsorbing contaminants from cooking oil
A structure for adsorbing contaminants from cooking oil comprises: an outer shell comprised of a filter material; and an adsorbing mixture comprising rice hull ash blended with a reinforcing binder, wherein the adsorbing mixture is in the form of particles having a particle size from about 0.30 millimeters (300 microns) to about 1.40 millimeters (1400 microns), with an average particle size of about 0.60 millimeters (600 microns) to about 0.70 millimeters (700 microns). The adsorbing mixture is enclosed by the outer shell, such that, in use, cooking oil with the contaminants passes through the outer shell, contacts the adsorbing mixture within the outer shell, and then again passes through the outer shell with substantially fewer contaminants.
