Abstract
Abstract A method of coating a surface of an article of food with a granular material at a selected density by transporting the food along a preselected path at a preselected speed, enclosing and agitating the granular material with a rotating auger, metering the granular material with height adjusting augers, while adjusting the height of the agitating auger, the orifice for metering the granular material and rotating the distributing auger at selected speeds to meter a selected quantity of food onto the food surface; reclaiming excess granular material and reconveying the excess back to the enclosed quantity.

Claim 1
Independent Claim
266 words
A method of coating a surface of an article of food with granular food product at a selected density comprising the steps of transporting an article of food to be coated along a preselected path at a predetermined speed; enclosing a quantity of granular material to be coated on said article of food above said preselected path; agitating said granular material with height adjustable rotatable agitating auger; metering said agitated granular material with a pair of height adjustable rotatable distributing augers to a distributing surface forming a pair of elongated parallel slots positioned normal to the preselected path and having an adjustable orifice plate to define an opening between the elongated slot and orifice plate above said predetermined path and through which a metered quantity of granular food material enabling an article of food to be coated to pass thereunder; adjusting the height of the agitating auger and distributing auger relative to the elongated slots at a selected height to enable a controlled weight of granular material to be metered from the agitating auger to the elongated slots in a circular pattern by said distributing auger; adjusting the orifice plate to set the opening defined by the elongated slots and orifice plate at selected cross-sectional areas for passing the metered quantity of granular material therethrough at a selected density and onto an article of food located thereunder; and rotating said distributing augers and said agitating auger at a variable selected speed required to meter a selected quantity of granular material through said openings and onto said article of food being transported therepast at said predetermined speed.
Claim 2
Independent Claim
266 words
A method of coating a surface of an article of food with granular food product at a selected density comprising the steps of transporting an article of food to be coated along a preselected path at a predetermined speed; enclosing a quantity of granular material to be coated on said article of food above said preselected path; agitating said granular material with height adjustable rotatable agitating auger; metering said agitated granular material with a pair of height adjustable rotatable distributing augers to a distributing surface forming a pair of elongated parallel slots positioned normal to the preselected path and having an adjustable orifice plate to define an opening between the elongated slot and orifice plate above said predetermined path and through which a metered quantity of granular food material enabling an article of food to be coated to pass thereunder; adjusting the height of the agitating auger and distributing auger relative to the elongated slots at a selected height to enable a controlled weight of granular material to be metered from the agitating auger to the elongated slots in a circular pattern by said distributing auger; adjusting the orifice plate to set the opening defined by the elongated slots and orifice plate at selected cross-sectional areas for passing the metered quantity of granular material therethrough at a selected density and onto an article of food located thereunder; and rotating said distributing augers and said agitating auger at a variable selected speed required to meter a selected quantity of granular material through said openings and onto said article of food being transported therepast at said predetermined speed.
Claim 3
Dependent Claim
40 words
The method of claim 1 further comprising the steps of reclaiming excess granular material passed through said opening and falling past said article of food being coated; and reconveying excess granular material back to the enclosed quantity of granular material.
