Double Screw Extruder

The advantages of twin screw Extruder:

Twin screw extrusion has become the standard over time in several industries because it offers numerous advantages over

single screw extrusion:

· More consistency in production and control of product quality

· Increased productivity due to continuous processing, faster start up and shut down between product changes, quick changeover and

advanced automation

· Greater flexibility, with the capability to process a wide range of raw materials

· Optimized footprint thanks to energy and water savings

· Simple and easy to maintain and clean

There are different types of Twin-screw extruder:

1.Cold extrusion is used to gently mix and shape dough, without direct heating or cooking within the extruder. In food processing,it is used

mainly for producing pasta and dough. These products can then be subsequently processed: dried, baked, vacuum-packed, frozen, etc.

2.Hot extrusion consists of thermo-mechanically transform raw materials in short time and high temperature conditions underpressure.

In food processing, it is used mainly to cook biopolymer-based raw materials to produce textured food and feed products, such as ready-to-eat

breakfast cereals, snacks (savory and sweet), pet foods, feed pellets, etc.

3.Steam-induced expansion, means melt expansion at the die exit due to water flashing off, hence leading to highly expanded products.

Subsequent processing then determines the textural attributes of extruded products such as  crispness,crunchiness, hardness, etc. This

process is used to produce directly expanded breakfast cereals, snacks and crispy breads.

4.Expanded co-extrusion combines steam-induced expansion and filling injection, hence leading to expanded products with dual textures.

It is mainly used in breakfast cereals and snacks.
