Dosing powders

Sobatech dedicated years of efforts in bringing the most advanced and accurate continuous dosing hardware and software to market. This resulted in the flat bottom dosing hopper design that prevents flow through feeder challenges like arching and bridge building. Also, it prevents compressibility of the powders as a result of the increased headload after refilling. Sobatech’s gravimetric feeders ensure extreme high accuracies during both loss-in-weight as well as gain-in-weight operation.

Sobatech only works with gravimetric feeders which constantly measure the weight reduction per time unit. The weight is measured by using (digital) load cells; the foundation of the entire feeding system. The motor automatically alters its speed when a change is detected in the material flow. By running feeders in gravimetric mode, possible underlying variations in bulk density or screw flight loading are automatically corrected for and an extreme high dosing accuracy is achieved.

Sobatech developed its own tailor made open source software to control its feeders and other hardware involved in the continuous dosing of the ingredients. In Sobatech’s feeding technology there are no hidden programs nor protected passwords. The complete system is open and accessible to the customer.
