Frictional Extrusion Food Processing Line
A Frictional Extrusion Food Processing Line turns grain flours such as corn or rice into puffed snacks using a screw extruder. In this type of extruder, most of the heat comes from friction as the screw works the dough under pressure. When the hot mass leaves the die, the drop in pressure makes it expand. We build these lines in China and match each one to your product and rate.
How frictional extrusion works
The screw, barrel and die do most of the work. As the flour is compressed and sheared, its starch cooks and turns into a plastic melt. At the die, water in the melt flashes to steam, so the product puffs into balls, rings, sticks or curls.
Because the heat comes mainly from friction, these extruders are relatively simple to operate and suit basic puffed corn and rice snacks. Changing the die, screw speed and moisture changes the shape and texture.
What a Frictional Extrusion Food Processing Line includes
A full line usually runs from a mixer and feeder, through the extruder and cutter, to a dryer or oven and a flavouring drum. Many buyers add a food roasting oven or other finishing units, depending on the snack.
Typical values for this type
- Automation: semi-automatic to fully automatic, line-integrated
- Contact parts: stainless steel (SS304)
- Process: mechanical and thermal, specific to each stage
- Capacity: varies with the machines chosen and the line rate
These are typical values for such lines, not figures confirmed for one model. We set the layout after we know your recipe and output.
Ordering a Frictional Extrusion Food Processing Line
We ask for the raw material, the snack shape and the hourly output before we quote. Buyers usually ask us which dies come with the line and which parts wear first. We quote EXW, FOB, CFR or CIF from China to Bangladesh, Brazil, Ecuador and beyond.
