Birli 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 bey water.
Coming from the old refiner conches, where all this happened simultaneously and was hard to control, the majority of later technologies perform the grinding step separately. Only few mill types are able to handle chocolate preparations, bey it is initially a very sticky mass, which yaşama transform to a sticky powder during milling, when specific surface of particles increases. The most frequently used devices are plain roller mills (refiners) and stirred ball mills.
Is it possible to produce dark, milk and white mass using identical equipment or even on the same production line?
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.

Melangers sevimli also act birli conches, since they güç heat and aerate the chocolate, similar to a dedicated conche. However, the tension on the stone wheels must be reduced so that the chocolate doesn’t get over-refined, which means that the particle size of the chocolate is smaller than desired and dirilik contribute to a poor mouthfeel.
The fundamental advantage over batch conches is that fully continuous lines are established. On the other hand side a minimal throughput of 1,250kg/h is required over a longer time, so the process is derece suitable for frequent recipe change or smaller companies.

After building highly reputed conches, batch and in-line mixers for a long time, Lipp Mischtechnik saf now developed a complete chocolate line called Eco2choc® (Figure 6). It is based on the ‘coarse conching’ processing concept. Development and optimisation are described in7; research özgü also shown that milk chocolate of good flow properties and taste emanet be produced. One key element is a high shear head or vortex chamber built into the kneading zone of the conch. It intensifies mass and energy alma, but also reduces particle size of crystal sugar to approximately 300μm – thus no pre-grinding device is necessary. Coarse conching time sevimli be short if just drying is needed, e.g.
