System and process for applying seasoning to a food item
Systems and methods for applying seasoning or flavoring to food items or products, for example, taco shells, are provided. A seasoning system can include a seasoning hopper or other storage container, a scarf plate, a scalping screen, a conveyor system, and a collection bin. The scalping screen can help reduce clumps in seasoning that falls onto the food items to allow for more even and consistent seasoning distribution. The conveyor system can include a mechanism for tilting or pivoting the food items to allow for application of seasoning to multiple surfaces of the food item as the food items are conveyed under the seasoning delivery system. A method for applying seasoning to food items can include adjusting process parameters such as presentation angle of the food items, throughput, seasoning flow rate, etc. to adapt to varying conditions such as temperature, humidity, and seasoning coverage.
1. A scalping screen configured to be attached to and receive seasoning from a distal end of a scarf plate, the scalping screen comprising:
a screened base;
two side walls attached to the screened base; and
a rear wall attached to the side walls and defining a gap between a bottom of the rear wall and a top surface of the screened base, the scalping screen having an open front edge along a side of the scalping screen opposite the rear wall;
wherein the scalping screen is configured to deliver a curtain of seasoning therethrough onto one or more food items being conveyed under the scalping screen and reduce clumps in seasoning falling through the scalping screen, and wherein the gap allows seasoning to fall off of both the front edge and a rear edge of the scalping screen to inhibit clogging in of the scalping screen.
2. A seasoning system for applying seasoning to a food item, the seasoning system comprising:
a scalping screen configured to be attached to and receive seasoning from a distal end of a scarf plate, the scalping screen comprising:
a screened base;
two side walls attached to the screened base; and
a rear wall attached to the side walls and defining a gap between a bottom of the rear wall and a top surface of the screened base, the scalping screen having an open front edge along a side of the scalping screen opposite the rear wall;
wherein the scalping screen is configured to deliver a curtain of seasoning onto one or more food items being conveyed under the scalping screen and reduce clumps in seasoning falling through the scalping screen, and wherein the gap allows seasoning to fall off of both the front edge and a rear edge of the scalping screen to inhibit clogging of the scalping screen.
3. The seasoning system of claim 2 , further comprising a conveyor system configured to convey the one or more food items along a path under the scalping screen to thereby allow the food items to receive the seasoning thereon, the conveyor system comprising four conveyor lines configured to convey a plurality of rows of food items under the scalping screen to allow the food items to receive seasoning thereon, wherein each of the four conveyor lines is spaced about 3.5 inches from an adjacent conveyor line.
4. The seasoning system of claim 2 , further comprising a conveyor system configured to convey the one or more food items along a path under the scalping screen to thereby allow the food items to receive the seasoning thereon, the conveyor system comprising a mechanism for adjusting a tilt angle of the food items as they pass under the scalping screen to an angle in the range of about 30° to about 70° to adjust a presentation surface area of the food items, thereby improving seasoning distribution and coverage on the food items.
5. The seasoning system of claim 2 , further comprising a conveyor system configured to convey the one or more food items along a path under the scalping screen to thereby allow the food items to receive the seasoning thereon, the conveyor system comprising a mechanism for adjusting a tilt angle of the food items to adjust for environmental temperature and humidity conditions.
6. The seasoning system of claim 2 , wherein the distal end of the scarf plate comprises a bias-cut edge and the scalping screen is configured to be attached to the scarf plate along the bias-cut edge.
7. The seasoning system of claim 2 , wherein the rear wall is configured to be attached to the scarf plate.
8. The seasoning system of claim 3 , wherein the scalping screen extends across the conveyor lines at an angle relative to an axis perpendicular to the conveyor lines.
