ZSK Food Extruders

The ideal extrusion system for many types of food and pet food

Coperion’s twin screw extruder ZSK Mv PLUS provides ideal conditions for the extrusion of many types of food and pet food products. The process section of the ZSK twin screw extruder consists of several barrels in which the co-rotating screws operate. The closely intermeshing screws with their tight selfwiping profile eliminate stagnant zones over the whole length of the process section. The effect of this is a constantly high conveying efficiency and perfect self-cleaning.

The modular design of the ZSK Mv PLUS and its unusual combination of free screw volume, screw speed and torque enable this twin screw extruder series to be individually configured for every application. The complete portfolio includes a wide range of sizes, allowing customers to process any required throughput range from laboratory to production scale.

TECHNICAL ADVANTAGES

SCREW VOLUME

The deeply cut screw flights with a diameter ratio Do/Di of 1.8 result in a very large free screw volume.

• Improved feed intake of additives with a low bulk density such as flours, starches, pigments, fillers, additives
• Lower shearing
• Reduced thermal stress on the raw materials
• Longer residence time for reaction processes
• Safe devolatilization

SCREW SPEED

The ZSK Mv PLUS series is designed for speeds up to 1,800 rpm.

• Increase in throughput by up to 3 or 4 times in comparison to the preceding ZSK Mv model
• Lower investment and operating costs due to smaller machine sizes at the given throughput rate
• Favorable price-performance ratio

SPECIFIC TROQUE

The specific torque of the ZSK Mv PLUS is 11.3 Nm/cm3. It has been increased by 30% in comparison to the preceding ZSK Mv model.

• Another increase in throughput of up to 40% in comparison to the preceding series
