High accuracy flavouring line is based on new weighing system.
Capable of 500kg an hour, the line incorporates a new Weighwright closed loop control to provide the particularly high dosing accuracy required.
Product enters via the Weighwright, a high accuracy vibratory weighing conveyor developed to provide a low maintenance and easy clean alternative to systems that use conveyor belts. It provides mass flow measurement of the material fed into the rotary flavouring drum, allowing the dose rate of powder and liquid additives to be adjusted in proportion.
The drum is inclined to achieve a continuous flow of product and is equipped to handle both powders and caramel coating. For powders, oil is first introduced by an atomising spray lance, followed by the flavouring, which is dispensed by a tapered edge vibratory feeder that provides an even dosing rate over its entire one metre length. For caramel coating, only the spray lance is employed.
Liquids are handled by a variable speed pump while the powder is metered via a horizontal auger. Both are adjusted automatically by the control system to match the product flow rate measured by the Weighwright conveyor.
Discharge from the flavouring drum is fed onto the infeed belt of the dryer, where a Wright Machinery oscillating conveyor ensures even coverage. Wright Machinery also supplied the vibratory conveyors that carry finished product to the multihead weighers and bagging equipment.
