Puff Snacks Machine / Snacks Food Manufacturing Line / Corn Snacks Twin Screw Extruder

Our snacks extrusion production lines can process various cereal based snacks – uncoated, coated or filled with a wide variety of recipes and shapes.

These snacks food manufacturing lines are with unique twin-screw extrusion technology and are highly flexible and scalable. They can be quickly and economically modified to manufacture innovative new products such as filled products, chips or snacks, with simple-to-install additional equipment.

HOW DOES AN EXPANDED SNACK PRODUCTION LINE WORK?

Once they are prepared, controlled quantities of raw materials and process liquids are premixed and then dosed to feed the extrusion platform continuously and consistently. The homogeneous mix thus created by the action of two co-rotating screws is subjected to thermo-mechanical processing to gelatinize the starch and cook the product. The paste is then pushed through the die to shape, expand and give the product its light and airy finished texture. The design of the die insert, the moisture content in the extruder and the expansion ratio are key factors in determining the texturing and shaping of expanded snack products.

At the extruder exit, the expanded product is either cut directly at the die head or conveyed on a belt to be cut by a post extrusion cutting system. The product can also be filled (injection of the filling at the level of the die) when the unit is equipped with a co-extrusion module.

Shaped snacks are transported on a belt dryer at a controlled temperature to achieve the target level of moisture content. The dried product is then cooled for storage or directly conveyed to the coating system. Two types of coating are used: an oil/flavours mixture to produce a slurry to be applied directly to the snack or, alternatively, an oil spray and dusting with flavours, spices, salt and other powdered materials. The flavored snacks are then cooled to room temperature before being transported to the packaging units.
