Continuous mixing of confectionary ingredients

Subject: Continuous feeding-mixing system

Clients: Systems commissioned for high volume, quality food manufacturers
Description: Feeding and mixing of confectionary ingredients, chocolate and beverage powders for continuous production processes
Product characteristics: Diverse range of ingredients with differing flow properties such as sugar, pectin, citric acid, cocoa, vanilla, tea and sodium bicarbonate. Particle size range from breakfast cereal flakes to fine powders.
Requirement: Volume based production, accurate metering, high degree of homogeneity, low headroom, easy to clean, and low capital investment.
Gericke technology: Each ingredient is transported to gravimetric “loss-in-weight” feeders controlled by a single Gericke UC 500 microprocessor. This calculates the recipe and controls the throughput of all feeders. These units meter the product directly into the GCM continuous mixer from where the mixed product is delivered to the onward process.
Special requirements: Continuous mixing is often used for small final packages and sachets due to high degree of ingredient dispersion. Systems are fully automated with easy clean features.

Gericke have developed this key process equipment in the form of gravimetric feeders and continuous mixers from their own research and development programmes. The system is particularly successful in processing fragile components without damage and the inclusion of liquids to a high proportion. Continuous mixing has many advantages:

High degree of homogeneity

No product separation

Automated handling techniques (no containers or bags)

Small space requirements

Low power consumption

Minimal source for impurities

The equipment is mobile and easily cleaned within a controlled environment such as a wash station, which can be remote from the production area. Liquid injection can be used for agglomeration processes.

Control of the plant is from a single PLC based panel incorporating operator interfaces and graphic visualisation. The feeder controller forms an integrated part of the overall system PLC.
