Roller system adapted to be used in relation to a flattening apparatus for flattening foodstuff

A flattening apparatus for flattening foodstuff, said flattening apparatus comprising:

• an impact resistant system,
• a first conveyor belt including a first face and an opposite second face, said first conveyor belt being arranged opposite to said impact resistant system with the first face of the first conveyor belt facing said impact resistant system, the area between the first face of the first conveyor belt and the impact resistant system defining a flattening area, and
• two roller systems, each of the roller systems comprising at least one helical outwardly protruding surface structure, each of the roller systems being rotatably mounted adjacent to the second face of said first conveyor belt distally away from said impact resistant system across the first conveyor belt, said flattening of the foodstuff including rotating said roller systems while conveying the foodstuff through said flattening area such that said at least one helical outwardly protruding surface structure contacts the second face of the first conveyor belt and thereby presses the first face of said first conveyor belt towards said impact resistant system causing a compression of the foodstuff within the flattening area,
• wherein said at least one helical outwardly protruding surface structure is askew in relation to a longitudinal axis of the respective one of said roller systems and is designed such that at least a portion of the at least one helical outwardly protruding surface structure is in contact with the second face of the first conveyor belt substantially at all times during rotation of said roller systems,
• wherein said at least one helical outwardly protruding surface structure is designed in a spiral shaped way, and
• wherein said roller systems are arranged below the first conveyor belt and in contact with the second face of the first conveyor belt, one of the roller systems is located downstream from the other roller system, and parallel to each other, and
• wherein the helical outwardly protruding surface structure of the two roller systems have opposite helical twist orientations, such that the twist helical orientation of one of the two roller systems is twisted in a direction opposite from a twisting direction of the other twist helical orientation of the other one of the two roller systems.
