Mixing several powders or granules is a frequent operation in all areas of industry.
Batch or batch mixing technology is preferred when production requires frequent recipe changes, either in terms of the number of ingredients or the variation in proportions.
On the one hand, the continuous mixer is essential when the downstream process is continuous: feeding an extruder, a packaging machine, a continuous dryer... but also when a compact solution is required to facilitate cleaning operations. The average residence time of products in the mixing chamber is around 30 seconds. For example, a mixer with a chamber volume of 50 liters, which is easy to clean, can handle a flow of 5 m3/h depending on revenue.
This compactness also makes it possible to mix ingredients incorporated in very low proportions (less than 1 per 1,000), while achieving the very high, reliable mixing qualities required in the pharmaceutical industry.
The short dwell time coupled with the very low rotation speed of the rotor blades will be a decisive advantage when mixing fragile products.
Gericke has been manufacturing batch and continuous mixers for over 80 years, with installations worldwide. In the vast majority of cases, preliminary tests are carried out in one of Gericke's stations, enabling customers to validate the quality of the mixed product.
