Co-Extrusion – Liquorice/Sugar Paste

BCH also offer a solution for the production of sugar paste which comprises of a sugar mucilage cooker and a Z-arm duplex trough mixer. The resultant sugar paste supplies the side flow extruder in order to produce the combination extrusion of sugar and liquorice paste.
The mucilage cooker is a steam-jacketed vessel with an anchor type stirrer which can be complemented by a high shear mixer. The combination of these two mixers together with the steam heating, results in a fully homogenous syrup mix.
The vessel is load cell mounted with microprocessor and recipe controls. The syrup is transferred to the Z-arm duplex trough mixer by a positive displacement pump and jacketed pipework. Icing sugar is fed into the mixer, and together with the sugar syrup the resultant mix produces a sugar paste. The Z-arm duplex trough mixer is robustly designed to give a thorough mixing action, prior to tipping into empty mobile bins.
The mobile bins are transferred to the extruder and mechanically tipped into the feed hopper of the sugar paste extruder.
The addition of a specially designed die head is used for the production of liquorice and sugar paste in a number of combinations.

Extruder

In a confectionery context, the BCH Extrusion system is the method of forcing a mixed (and often cooked) mass through a die that’s engineered to a desired shape. This profiled shape is then usually cut to a desired length using a BCH guillotine.
Primarily designed to handle liquorice, starch gels, fruit twist and sugar pastes, these extruders can also handle viscous food pastes and gels.

Side Flow Extruders
The extruders are manufactured with 75, 130, or 200mm diameter screws to achieve throughputs of between 50-1,500 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 design with good uniformity of product weight across the die width. The uniformity of the product weight is achieved by careful design of the screw across the die mouth; regulating/throttling plates/screws on the dies and for some products, a positive displacement pump on each rope.
The extruders are usually mounted on rails to position the dies over a retracting nose piece on the BCH high-performance cooling tunnels. For die changing and cleaning, the extruders can be wheeled offline.
The main barrel of the extruder is water jacketed to minimise start up times, maximise extrusion efficiency and in the case of the twin screw mixer extruder, provide heat transfer.
