MPF24 Small Batch Twin Screw Extruder

Used for development work and low output production runs, the MPF24 is ideal for experimental and laboratory use. It is used to try out new ideas, assess ingredients, provide test marketing samples, and make small batches of product with high-value ingredients.

Process optimisation, sophisticated control

The clam-shell barrel can be opened at any time to assess the state of processing, allowing screw section profiles to be optimised. Sophisticated controls include date capture, trending, and recipe function.

Wide product range

Products range from standard direct expanded curls, rings and puffs to complex multi-component premium products. Flavours and colours can be added easily.

Reliable scale-up

Full, reliable scale-up to outputs from Baker Perkins’ range of production scale food extruders is possible with comparable screw geometry.
