FAQ

Q: What are the functions of snack food extruder?

A: When the snack food extruder puffs food, it will have some effects on the food. It includes cohesion, degassing, dehydration, and swelling function. After these, puffed food has a bright color, fine texture, and rich taste.
Cohesion——During the puffing process, food or raw material can be tightly combined to form small discrete pieces.
Degassing——If food or raw materials contain bubbles ,the bubble will be removed during the puffing process.
Dehydration——During the puffing process, the moisture content of the raw material will be lost by 4%-7%.
Swelling——The bulk density of the material will change during expansion, such as sinkability or floatability.

Q: How does snack food extruder work?

A: The principles of operation in snack food extruders include raw materials are fed into the extruder barrel and the screw(s) then convey the food along it. Further down the barrel, smaller flights restrict the volume and increase the resistance to movement of the food. As a result, it fills the barrel and the spaces between the screw flights and becomes compressed. As it moves further along the barrel, the screw kneads the material into a semi-solid, plasticized mass. If the food is heated above 100ºC the process is known as extrusion cooking (or hot extrusion). Here, frictional heat and any additional heating that is used cause the temperature to rise rapidly. The food is then passed to the section of the barrel where pressure and shearing is further increased due to smaller flight. Finally, it is forced through one or more restricted openings (dies) at the discharge end of the barrel as the food emerges under pressure from the die, it expands to the final shape and cools rapidly as moisture is flashed off as steam. A variety of shapes, including tubes, rods, spheres, strips, doughnuts, squirls or shells can be formed. Typical products include a wide variety of low density, expanded snack foods and ready-to-eat (RTE) puffed cereals. Cold extrusion, in which food temperature remains at ambient is used to mix and shape foods such as pasta and meat products. Low pressure extrusion, at temperatures below 100ºC, is used to produce, for example fish pastes, surimi, liquorice and pet foods.

Q: What are different types of snack food extruders?

A: There are mainly two types of snack food extruders:
Single-screw snack food extruders feature a lone rotating screw within a metal barrel, available in various patterns, with a common design having a constant pitch. Raw materials in granular form are introduced through the hopper in the feed section. The screw’s rotation moves the material to the transition section, where the screw channel becomes shallower, compacting the material. Significant mechanical energy dissipation occurs, raising the material’s temperature and causing starch gelatinization, enhancing cohesion. The material proceeds through the metering section ultimately pushed through the die opening. Barrels of single-screw extruders typically incorporate helical or axial grooves on inner surfaces to facilitate more effective material conveyance an mixing.
Twin screw extruders feature two parallel screws of equal length rotating inside the same barrel, typically with a smooth internal surface. More complex than single screw extruders, they offer increased flexibility and superior control. These extruders are suitable for high-moisture applications, products with higher component quantities like fibres and fats, and more intricate products. Four configurations are possible based on screw position and rotation direction: (i) Co-rotating intermeshing screws; (ii) Co-rotating nonintermeshing screws; (iii) Counter-rotating intermeshing screws; (iv) Counter-rotating non-intermeshing screws.Intermeshing screws increase material residence time, while non-intermeshing screws induce greater shear, especially when rotating in opposite directions. Twin screw extruders offer versatile handling of viscous, oily, sticky, or wet materials up to 25% fat content.

Q: What is the production process of puffed snacks with the puff food extruder machine?

A: Add appropriate seasoning to the powdery raw materials and stir.
Add the raw materials to the automatic feeder or use a screw conveyor to continuously add raw materials to the feeder.
The automatic feeder can add a certain amount of raw materials to the extruder at a uniform speed.
The inside of the extruder spirally squeezes and pushes the raw materials forward to the high-temperature and high-pressure forming cylinder.
The raw materials are continuously heated in the forming cylinder of the puff snack extruder, puffed, softened, and extruded from the discharge die.
After the extruded food is extruded from the discharge die, it will be quickly cut into small pieces of uniform length by the rotary cutter of the discharge port.
The puffed food after cutting can be further fried, seasoned and cooled.
