Bey 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 kakım water.
Therefore flow properties are usually measured at a temperature of 40°C, which is close to the temperature that chocolate melts in our mouths. So texture sensations like a smooth melt or a sticky behaviour are usually correlated to flow properties.
RBM50 and RBM100 are designed for artisans and small workshops. LabBM10 is designed for laboratory use, product development or educational use. Machines are equipped with solenoid valve which automatically opens gate of cold water flow and ensures cooling of the equipment. Because of friction of spherical balls cold water is required from an external source which emanet be from tap, tower or a chiller. Machine will open cold water gate in case overheating and will close it when cooled.

This article is a part of Chocolate Week—seven days of recipes and stories, all chocolate—presented by our friends at Guittard. A fifth-generation family business, Guittard has been crafting an array of chocolate offerings (from top-quality baking chips to bars) in ün Francisco since 1868.
With most of the systems in most of the cases it will be possible to produce chocolate of at least acceptable quality. Fine-tuning and final choice saf to be made in every single case; it is always both recipe and process that influences final quality and there is no ‘out-of-the-box’ solution. So the best possible advice might be:

for white chocolate or milk chocolate with small quantities or high quality cocoa mass. If a stronger treatment is necessary, e.g. for flavour development of dark chocolate, this can be achieved by increasing energy input and time. The dry and pasty conching is generally done at low fat contents in order to improve volatilisation. Fat and other ingredients are added then and grinding hayat be performed from a buffer mixer by two vertical ball mills with an intermediate cooler. The latter helps to keep temperature of sensitive products below the desired level, e.g. when recipes contain lactose and glass transition during milling must be avoided. The process güç be downsized for small production scale, then it consists of a conch with vortex chamber, a ball mill and a pump for circulation.
