Abstract: The seasoning applicator applies seasoning onto snack food products such as potato chips, corn chips, tortilla chips, and the like in a two-dimensional seasoning pattern. A two compartment sifting assembly has a first top layer having a screen where seasoning is initially deposited. Upon vibration, the seasoning is passed through the top layer screen into a lower compartment. Therein, the seasoning is further distributed across the surface of the lower layer screen, which generally has a screen with smaller openings than the top layer screen. This promotes the even distribution of seasoning through the lower screen. Thereby, a two-dimensional seasoning pattern is created for depositing on a moving bed of snack food products.
