Bonnot Model 2 Extruder

• Producing expanded snacks and cereals.
• Forming pasta and noodle products.
• Creating pet food kibble and treats.
• Manufacturing textured vegetable protein (TVP).
• Extruding confectionery items and liquorice.

Typical capacity

For this class of single-screw extruder, throughput can range from approximately 50 kg/hr up to several hundred kg/hr, depending on product and screw configuration.

Power supply

Units of this type commonly require a 3-phase industrial power supply, typically 400V, 50Hz in the UK.

Extruder type

This is a single-screw extruder, suitable for a wide range of food processing applications.

Temperature control

Jacketed barrels are commonly found on units of this type, allowing for precise temperature management during extrusion.

Speed control

Variable speed drives are typically integrated, offering flexibility in process control and product characteristics.

Mounting

Units are commonly mounted on robust base frames for stability and ease of integration into production lines.

• What is the primary difference between a single-screw and a twin-screw extruder?

  Single-screw extruders are generally simpler and more cost-effective, often used for products requiring less shear and mixing. Twin-screw extruders offer greater flexibility, more intense mixing, and better control over shear and temperature, suitable for a wider range of complex products.

• Can this extruder process different types of raw materials?

• What kind of maintenance is typically required for a food extruder?

• Are spare parts readily available for Bonnet extruders?

• What are the typical safety features on an industrial food extruder?

Food extruders are valued for consistent output and material processing capability. Buyers typically prioritise equipment condition, motor performance and barrel integrity when purchasing used models. Industry sentiment favours machines with documented maintenance history and clear operational records. Common strengths include durability of construction, capacity for varied product formulations, and relatively straightforward operation. Worn components and seal degradation represent typical wear concerns requiring inspection before purchase.
