Colour & Flavour Mixing

Problem

A well known manufacturer of a leading brand of yogurt was using conventional inline dynamic mixing equipment to blend colours and fruit flavours into yogurt, but was experiencing poor control and colour streaking in the finished product.

For unknown reasons, some colours were more difficult to mix than others and as three or four different flavours and colours were being packaged simultaneously, this resulted in very high product wastage and equipment downtime.

Solution

Colour & Flavour Mixing: Statiflo Series 200 Motionless Mixers in sanitary stainless steel construction were recommended to replace the existing dynamic mixer. Complete mixing was assured as a result of the flow division mixing mechanism which is independent of flowrate and viscosity. The low shear mixing characteristic was proposed to avoid degradation and break up of fruit particles in some product lines.

Result

Colour & Flavour Mixing: Installation of the Statiflo Motionless Mixer was an immediate success. Colour streaking was eliminated with consistent product quality and no wastage. Having proved the technique, additional Statiflo Motionless Mixers were installed on other product lines on different flavours and colours. Simultaneous dispensing and packaging was then possible with complete confidence. The customer also benefited as a result of the Statiflo Mixer operating without moving parts, without spare parts and with virtually no maintenance requirement.

MIXER TRIALS

Colour mixing is highly unpredictable. The amount of mixing required is subject to the type of colour, colour intensity and appearance to the naked eye. Statiflo has an extensive library of existing colour mixing applications in all industries, however, in some circumstances, we recommend that mixing trials are performed if the amount of mixing to achieve product specifications is unknown.
