Method, apparatus, and system for coating food items
A method, apparatus, and system for coating food items such as coating empty ice cream cones subsequently containing ice cream. A liquid recovery apparatus is used in the method, apparatus, and system and is fashioned in a tray-like manner to form a slideway that includes a bottom section with openings that have collars along with opposing sidewalls and endwalls that together enable containment of coating liquid such as a chocolate coating. The chocolate coating is recovered and thereby reused as a subsequent topping for the filled ice cream cone.
1. A liquid recovery apparatus for use in coating food items, said apparatus comprising:
a bottom section having at least one opening, each said opening including a collar;
a first sidewall arranged perpendicular to said bottom section;
a second sidewall arranged perpendicular to said bottom section and parallel to said first sidewall;
a first endwall arranged perpendicular to each of said first and said second sidewalls and said bottom section;
a second endwall arranged perpendicular to each of said first and said second sidewalls and said bottom section and parallel to said first endwall;
a recovery means for recovering coating liquid, said recovery means located nearer said first endwall;
wherein said bottom section, said first sidewall, said second sidewall, said first endwall, and said second endwall enable containment of coating liquid therein for recovery by said recovery means and
wherein said bottom section includes a hollow cavity for circulation of a heating medium which warms said apparatus.
2. The apparatus as claimed in claim 1 , wherein each said collar is formed by a truncated cone with a larger circumferential opening of said truncated cone occurring adjacent said bottom section and a smaller circumferential opening of said truncated cone occurring a predetermined distance from said bottom section.
3. The apparatus as claimed in claim 1 , wherein each said collar is formed separate from said bottom section such that each said collar forms an insert that is removeably fixable and adaptable to receive a food item of varying size.
4. The apparatus as claimed in claim 2 , wherein said predetermined distance enables a food item no wider than said smaller circumferential opening to be inserted within each said collar and thereby rise at least one inch into said apparatus.
5. The apparatus as claimed in claim 1 , wherein each said collar is formed from food-grade plastic and said bottom section, said first sidewall, said second sidewall, said first endwall, and said second endwall are formed from stainless steel.
6. The apparatus as claimed in claim 5 , wherein each said collar is removable.
7. The apparatus as claimed in claim 1 , wherein said apparatus further includes a recessed area located adjacent said first endwall for pooling coating liquid.
8. The apparatus as claimed in claim 7 , wherein said recovery means includes a suction device for evacuating said recessed area of any pooled coating liquid.
9. The apparatus as claimed in claim 8 , wherein said apparatus is movable along an arc formed about a pivot point located adjacent said first endwall so as to facilitate movement of coating liquid towards said recessed area by forces of gravity.
10. A system for manufacturing a coated food product, said system comprising:
a holding mechanism for moving one or more food items into a fixed position;
a first spraying mechanism for coating each of said one or more food items;
a liquid recovery apparatus including a bottom section having at least one opening, each said opening including a collar engageable with each of said one or more food items, a first sidewall arranged perpendicular to said bottom section, a second sidewall arranged perpendicular to said bottom section and parallel to said first sidewall, a first endwall arranged perpendicular to each of said first and said second sidewalls and said bottom section, a second endwall arranged perpendicular to each of said first and said second sidewalls and said bottom section and parallel to said first endwall, and a suction device for recovering excess coating liquid collected within a space defined by said bottom section, said first sidewall, said second sidewall, said first endwall, and said second endwall, said suction device located nearer said first endwall;
a pump mechanism operably connected to said suction device for evacuating said excess coating liquid;
a reservoir for holding said excess coating liquid;
a means for filling each of said one or more food items with an edible confection to form a food product; and
a second spraying mechanism fed from said reservoir for providing further deposits of said excess coating liquid on said food product.
11. The system as claimed in claim 10 wherein said coated food product is an ice cream cone and each said one or more food item is an unfilled wafer cone.
12. The system as claimed in claim 11 wherein said coating liquid is water-impermeable and edible and said excess coating liquid contains particles of said unfilled wafer cone in addition to said coating liquid.
13. The system as claimed in claim 12 wherein said coating liquid forms a uniform deposit on a rim and interior of said unfilled wafer cone and said excess liquid coating forms a topping layer upon said ice cream cone.
14. The system as claimed in claim 13 wherein said first spraying mechanism includes a spray angle in a range of between 20 and 50 degrees centered on said unfilled wafer cone and each said opening allows a wafer rise in a range between 1 and 2 inches.
