Extrusion is a popular food processing technique that includes compressing food products through tiny slots with a single or a sequence of screws, then baking them at high temperatures before enclosing them in a container.
Extrusion is now used by the majority of food and snack companies to create their goods. It’s a considerably more compact and efficient process than traditional production, which often includes more time, money, and equipment.
Consider the production of breadcrumbs. The traditional method entails mixing the ingredients, shaping and baking the bread, and discarding it before grinding. Using only a twin-screw extruder, the identical product may now be produced. The technique offers greater flexibility, permitting seamless transitions between multiple recipes, in addition to significant labor, energy, equipment, and space savings.
In the food business, twin-screw extrusion is becoming increasingly popular. We’ll discuss some of the reasons for it in this blog.
Enhanced Productivity
Twin-screw extruders are far more adaptable than single-screw extruders and can manage a wider range of mixed formulas, raw materials, and intricate recipes. Furthermore, twin-screw extruders do not experience performance drops when the screws wear out like a single-screw extruder.
Better Mixing and Final Product
Interpenetrating twin screws as well as a variety of specific screw designs, such as geared mixing, reversed screw components, and kneading frames, are used in the twin-screw extrusion process to allow exact modification of the amount of shearing or mixing. This gives you more control over the quality and strength of your mixing. Single-screw extruders can only mix a small amount of material. This causes flow constraints, which ultimately decreases the extruder’s productivity.
Increased Flexibility
Because of their ability to handle a variety of processing operations simultaneously, such as cooking, mixing, chilling, heating, melting, venting, and so on, twin-screw extruders provide higher flexibility. A single-screw extruder is reliant on capacity and screw spin rate. When it pertains to various processing operations, screw configurations are likewise limited as well in the case of single-screw extruders.
Some Other benefits of Twin-Screw Extruders
Other notable benefits of twin-screw extruders are:
- Lower strain distribution and shear rate
- Excellent heat transfer through the connective screws
- Controlling the temperature profile with precision
