High Quality Twin Screw Extruder is the forcing or thrusting out of an object. Within most industries, extrusion is used in tandem with molds and cutting mechanisms to create uniform, identically-shaped and formed objects.

Within the food industry, contract extrusion can have many applications. It can be used in the production and packaging of cereals, noodles, cookie dough, and many other items commonly found in grocery stores. Twin-screw extruders are used to grind and mix ingredients before extruding them through a mold to the desired shape-High Quality Twin Screw Extruder.

On a twin-screw extruder, an engine powers two large, screw-shaped devices that rotate opposite one another. The distance between the two screws determines the size to which the ingredients are ground. The ingredients can also be heated or cooled throughout the food extrusion process-High Quality Twin Screw Extruder.

At the start of the extrusion process, raw ingredients are fed into the primary feed port. In nearly all cases, these are dry ingredients. Immediately after being fed into the machine, the ingredients are crushed and ground into ideally sized particles. In complex mixtures, an extruder may have multiple ports along its sides. These ports allow for mid-process additions of other ingredients.

The more ports, the more ingredients can be added into the mixture. This allows for the gradual combination of ingredients, to ensure ideal composition and integrity of the product. Twin-screw extruders are used primarily for mixtures, but single-components can be run through the extruder to achieve the ideal consistency and final product.

Now that the ingredients have been mixed, they can be heated, cooled, dried, or added into another mixture.

The ingredients or products, having been sufficiently ground and combined, move into the actual extrusion process. In this step of the process, they are forced through a die to give the product the desired shape. Think of it like pushing play dough through a mold. These die can be shaped in an incredible array of options, and can create hollow spaces as well as solid products.

Once pushed through the die, the shaped product is shorn off, and the extrusion process is complete. Depending on the product, the sheering can be rapid, for when the product is small, or slow, for when more of the product must be extruded before cutting it off.

One benefit of the extrusion process is in the quality and consistency of the finished product. It also allows you to replicate the exact product endlessly, so long as you continue to feed the ingredients into the extruder.
