Structure including rice hull ash and reinforcing binder for adsorbing contaminants from cooking oil

A structure for adsorbing contaminants from cooking oil, comprising:

• 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);
• wherein the adsorbing mixture is arranged to be 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;
• wherein the adsorbing mixture has a density of between approximately 300 g/l and 600 g/l;
• and
• wherein the outer shell encloses approximately 6 ounces of the adsorbing mixture.

• wherein the reinforcing binder is a granular clay that is in a range of 10-50% of the adsorbing mixture by weight;
• and
• wherein the adsorbing mixture is arranged to be 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.
