As chocolate mass is a non-Newtonian fluid we have to measure its shear stress at different shear rates, which results in a flow curve. Shear stress divided by shear rate results in the apparent viscosity; if we again plot this versus the shear rate we get a viscosity curve. Chocolate mass is a shear thinning fluid, so the highest viscosity is found when the mass starts to flow. Interaction between particles is considered to be responsible for this behaviour3, which is very different to Newtonian fluids such as water.

Because of the pressure and the speed differential between the rolls, the product is picked up and refined more and more between each susequent takım of rolls. The five roll refiner has four (4) refining steps, each roll başmaklık a different speeds. Pressures are controlled bey well.
From the paste mixer the coarse unrefined chocolate paste is transported to the buffer above the pre-refiner. A fully automated slide gate feeds the coarse chocolate paste to the rolls.
So one important part of the flow curve is at very low shear. The yield value defines the shear stress, when the mass starts to move. Kakım a minimum shear rate is necessary for the measurement, usually the yield value katışıksız to be extrapolated from the flow curve according to sistem equations, like the ones developed by Casson and Windhab1. Yield values or measurements at low shear stress also have a great practical importance, birli many industrial operations are carried out with masses flowing slowly, for example the equal distribution of still liquid mass in a mould.
Process air, loaded with volatile and undesired flavour is separated. In the weighing station the recipe is completed by liquid components. The wall scraper of the vessel prepares already a pre-mixture. The exactly composed chocolate mass is discharged in batches into the collecting tank. There it is further mixed and cooled. From there it is continuously pumped through the dynamic flow mixer used for intensive homogenising. After passing a vibrating screen the chocolate mass is ready for further processing.
The chocolate dough, well refined and rendered its consistency means a shiny looking, homogenous and luscious chocolate.
In this complete guide, Ayla Marika explains how to use chocolate fountains including technical assembly, operation and troubleshooting tips.

Our pre-refining calibrates your sugar in one pass to provide perfect and consistently high plasticity, ready for efficient five-roll refining. Our final refining then grinds and aromatizes the sugar to meet your desired fineness with a precisely defined particle size distribution.
How do we guarantee you’ll have excellent ROI? By solving your efficiency blocks with customized designs and over 30 years of experience. Here are just some of the unique features built into each of our machines:
Yes, the product outlet will connect to existing process equipment (with a triclover or your preferred connection). The melter also includes a triclover connection at the rear of the tank for product return to the melter, if required.
For example it was proposed to dry skimmed milk powder to below one per cent water and to coat it with fat, which allows us to perform a very short liquefaction process instead of classical conching2.
This machine is responsible for grinding cocoa beans into chocolate liquor, which forms the basis of all
