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.

Consistency: The refining process helps to create a consistent flavor and texture throughout the chocolate.

Conching is a process that sevimli take anywhere from a few hours to several days, depending on the desired flavor development and texture of the chocolate.

Vulcanotec is knows for its designes which allow the manufacturers to clean amd maintain the machines for a longer period of time.

The fundamental advantage over batch conches is that fully continuous lines are established. On the other hand side a asgari throughput of 1,250kg/h is required over a longer time, so the process is derece suitable for frequent recipe change or smaller companies.

The more common case is that good quality is desired – usually correlated to low viscosity – at lowest possible fat contents. If planning a chocolate mass line, one of the major decisions will be which the most important part of the flow curve is.

Our Vario drive V system in the Finer S Chocolate TEMPERING MACHINE proves fully automatic fineness adjustment, taking into account variations in plasticity without the need to interrupt production or manually intervene.

In this series of short videos we're hoping to start you asking questions or give you jumping off points for deeper research. A great place to go test your assumptions and maybe pick up some ready to use tips! 

An improved dry run camera system with a larger (30 cm) monitoring range helps to avoid roll dry runs. Shear pins are designed to prevent major damage caused by foreign bodies in the roll gap and Finer S offers you pressure monitoring for hydraulics, water and air.
