Twin Screw Extruder Enhanced Product and Production Safety by new Hygienic Design

In order to fulfill food manufacturers’ increasingly stringent health and safety stipulations, Coperion has completely revised its ZSK Mv PLUS twin screw extruder.

The core feature of this redesign is the twin screw extruder’s new open base frame. It is made of stainless steel, has only smooth surfaces and offers users numerous advantages: Its excellent accessibility markedly reduces the effort needed for cleaning the system. Product safety and production safety are both improved. The downtime required for cleaning the machine is reduced to a minimum. By using stainless steel Coperion is choosing a construction material that fulfills all European and global directives and guidelines.

The centric pelletizer ZGF is also made of stainless steel. This includes both the pelletizer unit itself and the drive. Therefore, there is no need of the cooling fins of a conventional air-cooled motor, which significantly reduces the cleaning effort.

Plant operators will also benefit from the new CSPro control system of the ZSK Mv PLUS. It is based on the latest Siemens PLC S7-1500 components and, thanks to the integrated OPC UA interface and web interface, provides for direct access to all the plant’s relevant data. The control system also complies with all Industry 4.0 standards.

The performance data of the twin screw extruder ZSK Mv PLUS is based on a Do/Di value of 1.8 (outer to inner screw diameter). Its specific torque is 11.3 Nm/cm³ and the maximum screw speed is 1,800 rpm.
