Food Machinery Conveying Stirring Filling Nylon Screw

Food Machinery Conveying Stirring Filling Nylon Screw Screw Conveyor Products The plasticizing screw can be divided into four zones according to its function: 1. Solid conveying zone This section is connected with the feeding funnel, and the plastic solid particles are tightly compressed to form a solid bed, which is subjected to the shearing effect of the melt cylinder, in addition to gradually increasing the temperature of the plastic, the plastic is transported forward. 2. Delay of melting This section is the area from the end of the solid conveying area to the area before the  formation of the melt pool. The viscous force (drag force) accumulates in the forward  screw groove, and the pressure formed at the end of this area is large enough to deform the solid bed, and the accumulation in the front screw groove gradually forms a melting pool.
