A Sobatech continuous mixing system uses a two phase process for mixing ingredients into a consistent and homogeneous mass. First, all ingredients are evenly and accurately distributed over the complete mass (phase 1 mixing: the homogenizer). Then, the development takes place (phase 2 mixing: the continuous mixer). This is done in a controlled and extremely precise way during kneading.
The production volumes range from 50 kg/hour to over 10,000 kg/hour. This can be accomplished in an employee free operational environment resulting in significant (labor) cost savings.
PHASE 1 MIXING: THE HOMOGENIZER
Both phase 1 mixing (the homogenizer) and phase 2 mixing (the continuous mixer) are based on the first-in / first-out principle. After gravimetrically dosing the powder ingredients, they pass through the homogenizer phase. In this phase the powders are, by means of medium pressure, injected by the liquid ingredients. The liquids enter the homogenizer in a pre-defined order. This non-mechanical way of blending the ingredients ensures a even hydration of the flour and better integration of the minor ingredients.
PHASE 2 MIXING: THE CONTINUOUS MIXER
The contra-rotating mixing tools of the continuous mixer (phase 2 mixing), are responsible for the controlled flow of mass throughout the mixer. The combination of a relatively little amount of product in the mixing chamber with a relatively high volume of tooling, result in a remarkable high energy efficiency. A large part of the energy developed by the mixer tooling is put into the product. The continuous mixer has the ability to apply exceptional high shear forces during kneading.
CONTINUOUS BENEFITS
The main benefits of continuous mixing include a high automation grade resulting in a product quality that is independent of the skilks/performance of operators. Also, continuous mixing results in a constant consistent product quality. Each piece of dough has the same age going through the process. Lastly, continuous mixing often simplifies the production process requiring no additional machinery to resize the batches.
