Advantages Of Continuous Mixing Over Batch Mixing

Within the industry, applications involving the mixing together of different powders and the addition of liquid to powders remain numerous.

To give just a few examples: addition of vitamins to foods, mixing of a range of components for the manufacture of detergent, production of chemical products, mixing of various raw materials in the manufacture of coatings.

These mixtures which were traditionally prepared in batch mixers are increasingly being prepared in continuous mixers.

Indeed, if the number of ingredients does not exceed 7 or 8 and if the recipes are stable over time, a continuous process offers numerous advantages.

Firstly the volume of the mixer is greatly reduced: a few tens of litres suffices to mix several tonnes per hour.

The result is that the installed electric power required for such flows does not exceed 2 or 3 kW.

If the operation downstream of the mixer is continuous, for example a packaging line, the product exiting the mixer does not need to pass through a buffer volume, which eliminates the risk of segregation.

The low speed of the continuous mixer combined with a mean dwell time in the mixer that does not exceed 60 seconds, ensures gentle mixing of the products.

Gericke continuous mixers are available in numerous designs suitable for the chemical, food and even pharmaceutical industries.

It is possible to process volumes from a few kilogrammes per hour to several tens of tonnes per hour.

Industrial scaled trials can be carried out in our, with full-scale machines equipped, Gericke Test Centre to check the product quality, while it is still in the development stage.

Gericke supply complete feeding, conveying, sifting and mixing systems.
