    Single screw extrusion:
     
     
     
    ·Product quality is more consistent in production and control
     
     
     
    ·Fast switching and increased productivity due to continuous processing, faster startup and product change closure
     
     
     
    Advanced automation
     
     
     
    ·More flexibility to handle all kinds of raw materials
     
     
     
    ·Save energy and water, optimize floor area
     
     
     
    ·Easy to maintain and clean
     
     
     
    There are different types of twin-screw extruders
     
     
     
    1. Cold extrusion is used to mix and shape dough gently without heating or cooking directly in the extruder. Used in food processing
     
     
     
    It is mainly used to produce pasta and dough. These products can then be processed: drying, baking, vacuum packaging, freezing, etc.
     
     
     
    2. Hot extrusion includes raw materials that undergo thermo mechanical transformation under short-term and high-temperature conditions.
     
     
     
    In food processing, it is mainly used for cooking biopolymer based raw materials to produce textured food and feed products, such as ready to eat food.
     
     
     
    Breakfast cereals, snacks (salty and sweet), pet food, feed pellets, etc.
     
     
     
    3. The expansion caused by steam refers to the expansion of the melt at the die outlet due to the flash evaporation of water, resulting in the high expansion of the product.
     
     
     
    Subsequent processing will determine the texture characteristics of the extruded product, such as brittleness, brittleness, hardness, etc.
     
     
     
    The method is used for directly producing breakfast cereals, snacks and crispy bread.
     
     
     
    4. Expansion coextrusion combines steam induced expansion and filling injection to produce expansion products with dual texture.
