Leistritz has long been established on the global market in the manufacturing of co-rotating twin screw extruders. After all, we have been building and optimizing extruders for more than 80 years - first for the plastics industry then also for the pharmaceutical and food industries. This is made possible not only by constant innovations and a ready ear for the users’ needs, but also by a dedicated team who bring many years of experience in this field to the table and stand behind the product with passion.
The Leistritz extruder series
The twin screw extruders from Leistritz convince with their compact and well thought-out construction, effective cooling and heating technology, and high quality and energy efficient drives. Alongside a modular barrel system, Leistritz offers a comprehensive system of various screw elements which offer great options for variation. The optimal layout of the screw geometry for each processing task is the art of our Leistritz process engineers.
ZSE MAXX series
The ideal combination of very high specific torque (up to 15 Nm/cm³) and a large volume (OD/ID = 1.66) in one extruder - this is the feature which makes the ZSE MAXX twin screw extruder stand out. An extremely large range of processes benefits from the maximal adaptability of the ZSE MAXX since it has high process engineering relevance. As a result processors no longer have to choose between high volume or high torque machines. They can get everything in one machine.
high, free volume in the screw (OD/ID = 1.66)
very high total torque due to patented splined shaft connection
increased cooling capacity by means of optimized flow of the liquid coolant through the barrel
very high available specific torque (up to 15 Nm/cm³)
Leistritz' extrusion systems for wet granulation and melt extrusion are globally established and are technological leaders. For the specific requirements in the sensitive pharmaceutical industry, we offer a range of extruders and corresponding additional equipment in GMP design. All machines have refined detailed engineering from a cleaning validation point of view as well as good process constancy in order to guarantee consistent product quality.
- closed processing unit to prevent cross contamination
- well-thought out GMP design
- state-of-the-art GxP control system
- scale-up of results from R&D to production machines
ZSE CC - twin screw extruder series
The co-rotating twin screw extruders of the ZSE CC (Classic Compounder) series has been designed for Asian customers with high quality standards. In the first instance four extruder sizes with screw diameters of 27, 40, 50 and 60 mm will be put on the market in 2016/17. The machines have an OD/ID of 1.50 and a specific torque of 10.5 Nm/cm³. The maximum screw speed is 1,000 rpm.
Advantages of the ZSE CC
- can be used for a multitude of compounding tasks
- self-cleaning screw profile
- easy-to-clean surfaces
- high screw speed up to 1,000 rpm
