Product descriptionThe ETT series twin-screw extruder is an industrial extrusion line designed for continuous production of snack foods, breakfast cereals and pet foods. The machine integrates feeding, extrusion, cutting, heating, lubrication and control subsystems. Core drive and metering units use variable-frequency speed control to provide stable, adjustable processing.
ApplicationsDesigned for processing starch-based and cereal raw materials, including corn flour, wheat flour, rice flour and native or modified starches. Suitable for producing fully expanded and semi-expanded extruded snacks, breakfast cereals and dry pet food formats.
Working principleRaw materials are dosed into the feeder and delivered to the twin screws. As screws co-rotate they convey, compress and shear the material. Temperature and pressure build in the compression and mixing zones until the mass reaches the desired plasticized state. Material is then conveyed to the die for shaping and cut to length at the discharge.
Key advantages- Food-grade construction and hygienic design for easy cleaning and contamination control.
- Adjustable processing parameters (speed, temperature, pressure) to tune product texture and expansion.
- High mixing and metering accuracy for consistent product size and formulation homogeneity.
- Wear-resistant alloy screws and water-cooled barrel for extended service life and processing of varied viscosities.
- Continuous high-throughput operation suitable for industrial production lines.
- Compatible with automation systems; electrical and pneumatic components allow integration with process control.
- Flexible recipe and parameter settings for product differentiation.
