Single-screw high shear extruder
Optimize your snack production with precise control over raw material transformation, from mixing to extrusion, ensuring consistent product quality and efficient throughput.

Extrudes Snacks with Precision and High Throughput
The single screw extruder from Lalesse Extrusion offers a high shear approach to snack manufacturing, ideal for producing diverse snacks like cereal puffs, crispy rice snacks, and flavored popcorn. Specializing in precision control of texture and density, this equipment supports capacities ranging from 80 to 300 kg per hour, with the actual throughput depending on the raw materials and snack shapes. The extruder integrates seamlessly into continuous, automated processing lines with variable speed control and full water-cooled processes. Its advanced direct drive system eliminates the need for V-belts, providing robust performance ideal for high-speed operations. Additionally, the split sleeve system enhances cost-efficiency, and the use of die inserts instead of plates offers a cost-effective customization option for various snack shapes. The machine is engineered for easy maintenance, with features like a hollow main shaft for quick screw removal, ensuring minimal downtime in your production line.
