Vacurema
Inline Application:
The upstream process:
Material is fed into the plant automatically (via silo and conveyor screw). It passes a vacuum slide into the reactor. In the reactor the material fed in is mixed, heated, dried and crystallised at the same time in one working step. Thanks to an appropriate dwell time at high vacuum and high temperature, residual moisture is removed very efficiently and quickly. This is essential for minimal IV loss. In particular no external predrying is necessary. In addition to this, rotating tools provide the force for efficient and continuous filling of the tangentially and directly connected single screw extruder.
The extruder screw takes the material, plastifies, homogenises and degasses it and directs it to a downstream large area fine mesh filter system with integrated automatic self cleaning system.
The downstream process for sheet production
… consists of e.g. a melt pump, manual die, 3-roll-stack, gauging system, antiblock, film accumulator, edge trimming station, edge trimming granulator, turret winder (supplied for example by Erema's partner SML).
