Coperion ZSK Food Extruder

Twin screw extruder ZSK Mv PLUS in a new hygienic design

Stuttgart, July 2016 – In order to fulfill food manufacturers’ increasingly stringent health and safety stipulations, Coperion GmbH, Stuttgart, Germany has completely revised its ZSK Mv PLUS twin screw extruder and given it an innovative machine design.

It meets the highest standards of hygiene and represents an improvement in both product safety and production safety.

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.

Coperion’s ZSK twin screw extruder is the result of more than 100 years’ experience with extrusion processes and over 50 years’ expertise acquired from dealing with food applications. It offers convincingly high operational reliability and highly durable components. A wide range of food companies around the world – from cereal producers to manufacturers of textured meat analogues – already deploy the ZSK Mv PLUS successfully.

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.
