Differences of single-screw & twin-screw extruder in the
DATE：2016/06/24
Differences between twin-screw extruder machine and single-screw extruder machine in aquatic feed processing :
1、Good production rate, up to 98% or more.
2、Perfect pellet shape, uniform grain shape. The stable die outing pressure of twin-screw insure the uniform of pellet shape.
3、The special strong pump sending ability in the twin-screw extruder machine could guarantee no anti-spray and clogging.The raw materials contain higher moisture after forced pre-conditioning. The feeding part in the single-screw extruder would anti-spray or clog.
4、Continuous stable production of a variety of products of small pellets. When process the small pellet,In the production 2mm diameter of the pellets and below, the single screw unstable conditions, the production rate will dip, type of material will deteriorate.
5、Density control is more stable and reliable. The material in the twin screw extruder barrel melt more fully, evenly, can be precisely controlled production of floating material, slow sinking submerged materials and products
6、Recipe for wide adaptability, can adapt to high-energy production formula. Twin-screw produce fat content of 11-13% (up to 17% referred to foreign data) of high energy formula, but generally no more than a single screw 6-8%.
