• The process section of all ZSK series is designed as a modular system. 
• It consists of several barrels in which the co-rotating screws operate.
• The advantage of this modular principle is its maximum flexibility in compounding and extrusion. 
• Different process zones are created alternately as required for conveying, plasticizing, mixing, and shearing, homogenizing, devolatilizing and pressure build-up to benefit from highest product quality and maximum throughput rates. 

• The temperature of every barrel can be controlled separately. The heating is usually electric by means of heater cartridges and heater shells; the cooling is achieved by water. 
• In addition, barrels can also be tempered with liquid or steam heating. 
• Standard barrels and screw elements are made of nitrided steel or in the enhanced wear and corrosion protected version of appropriate materials

• Maximum power density 
• Reliable scale-up
• Gentle product handling for maximum quality 
• Very wide range of wear protection solutions 
• Maximum screw speed 
• Comprehensive process engineering support 
• Maximum productivity 
• Flexible solutions for control system 

• Maximum conservation of resources by high efficiency 
• High reliability and proven technology of the machines 
• Maximum flexibility in product changes and machine modifications 
• Comprehensive after-sales services by worldwide 
• Optimum graduation of the machine sizes 
• Large number of application-specific solutions to increase throughput and productivity, e.g. quick-release features, side devolatilization ZS-EG, Feed Enhancement Technology (FET)

TVP is used as a meat substitute and as a supplement to meat products. It can be produced in various sizes and forms, as smaller pellets or larger chunks, broken down or ground. TVP is a dry, expanded product with a long shelf life under normal ambient conditions. TVP requires rehydration in water/liquid before use.

HMMA is primarily used as a high-quality meat-analogue product in ready-to-eat meals. By adjusting recipe and process arameters, structures of different meat types can be replicated with striking similarity to the original. HMMA's moisture content lies between approximately 50-80% and must therefore be refrigerated.
