Next, analyzes the single screw rod extruder with the double screw rod extruder characteristic as well as the production craft need, had determined digestion and agitation through the single screw rod extruder first, then uses the double screw rod to extrude the shaper formation the production process. In the base of the extruders in existence, we referenced the mature means of extruder design in our country and abroad and the special working craftwork requires of the snack foods, then, we improved the key structure of extruder. In this text, we introduced the structure design of extruder in detail, particular to the major parts: assignment tank, screw, barrel and systems analysis and calculating. To those important transmission parts: the big gear and the small gears in assignment tank, strip wheel, driving spindle, key, we made a design and check the intensity. And we calculate and check the carrying capacity of the bearing particularly. We also refer to the choosing requirements of the accessories: heating and cooling system, die, knife equipment, and made a simple design. In the end of the text, the installing, operation, controlling and repairing of the extruder were also introduced. Keywords: gears。assignment tank。Twinscrew Extruder V 目 錄 摘 要 ..............................................................................................................................................III ABSTRACT ..................................................................................................................................
