Counter rotating twin screw extruders for the production by means of extrusion of products like fruit pastes, soft candies, toffees, cereal and protein bars, chewing gums and bubble gums. This range of extruders are particularly suitable for producing products with a centre filling.Under high pressure the mass is constantly extruded in an even flow. It is possible to connect filling devices for powders, granultaes, semi-liquids or granulates to the extrusion head in order to make dedicated center filled products. If 2 or multiple extruders are combined, co-extruded products can be made. Because of a broad range of extruding heads and special nozzles, many combinations of shapes, flavours and colours can be made.
