This is our new type of extruder machine that was making bicolor puffed corn snacks. The normal twin-screw extruder can not produce snacks in two colors. It can make various snacks and pet food in double colors. What's more, the output is several times higher than that of ordinary twin-screw extruders and the power consumption is not much higher. The floor occupation is almost the same as an ordinary twin-screw extruder.
