Side Flow ExtrudersThe extruders are manufactured with 75, 130, or 200mm diameter screws to achieve throughputs of between 50-1,000 kg/hr. via a side flow die configuration. The side flow dies will extrude over widths from 300-1200mm at right angles to the screw axis. Side flow dies can be designed to extrude sheets, ropes and twisted ropes in solid, hollow or co-extruded form.The side flow design provides a cost-effective, high output system with good uniformity of product weight across the die width. This uniformity is achieved by careful design of the screw across the die mouth; regulating/throttling plates/screws on the dies.Twin Screw ExtrudersThis type of extruder enables the mixing of colours, flavours and acid into a base cooked liquorice mass between the extruder, manifolds and dies. Using this type of extruder, colour and flavour contamination of the premix and cooking equipment is eliminated, thus enabling rapid colour changes, minimal loss of flavour, minimal sugar inversion and starch gel breakdown. The extruder is fitted with a screw extraction system for rapid and easy inspection.Multi Colour Multi Flavour The process begins with a neutral cooked product being fed into the BCH Twin Screw Extruder. The product can be split up into 6 individual channels, each of which can be coloured and flavoured. The flow control of each colour channel to each rope is automatic, and no manual regulation of the machine is required, leading to quick start-up and guaranteed rope weight control, as well as equal and uniform colour and flavour streams. Ropes can be extruded in a huge variety of shapes and designs including twisted, straight, flat strap, squares and stars. They can also have hollow or filled centres.
