Introduction:
Twin screw puff corn extruder is a machine that is used for producing various snack foods like corn curls, chips, and pellets which are widely consumed around the world. This machine is specially designed to produce a high-quality product with a crispy texture, delicious flavor, and attractive appearance. The twin screw puff corn extruder is one of the most commonly used extruders for making snacks because of its efficiency and versatility.
Working Principal of Twin Screw Puff Corn Extruder:
The working principal of a twin screw puff corn extruder is very simple. In this machine, ingredients are mixed with water and then fed into the hopper of the machine. Here, the raw material is then conveyed to the screw chamber of the machine. The twin co-rotating screws inside the chamber work together to process the mixture, making it progressively hotter and converting it into a viscous mass.
The raw material goes through various stages during the extrusion process, with the screw barrel being divided into several zones. Each is characterized by a varying degree of heat, shear, and pressure. When the raw material enters the extruder, it undergoes the first stage called "Transportation zone," where the screws move the material forward into the machine. This zone is typically kept at a lower temperature than the other zones.
The second stage is called the "Compression zone." In this stage, the material is compressed and heated by the screws. This zone is maintained at a high temperature, usually above 100°C, to melt the starch.
The third stage is the "Cooking zone," where the mixture is cooked at a higher temperature, which can vary between 120 °C and 180 °C, depending on the recipe being used. The cooking zone is the most important zone in the extruder because it is here that the final product is formed. At this stage, the starch gelatinizes and the other constituents in the mixture start to react with each other, leading to the formation of a solid sheet.
The fourth stage is the "Expansion/Die zone," where pressure is released, and the mixture expands to produce a hollow or porous shape. The size and shape of the final product can be controlled by changing the die or adjusting the screw settings. The final product is then cut by the cutting system, which varies depending on the product being produced.
