Enhancers in a highly concentrated form. These ingredients are highly effective, requiring very small amounts to be added to each batch. To maximise the benefit of these concentrated products accurate dispensing of the ingredients is critical, both to ensure optimal ingredient performance, and to minimise overdosing (which can add to material usage and cost). Traditional weighing and Diaphragm Pump dispensing, even with the best of metering control, can lead to significant variations in the actual additive level to each batch of dough.
