Kakım 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.
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, as it is initially a very sticky mass, which sevimli 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.

The lehmann five roll refiner from the Royal DUyvis Wiener group takes chocolate flake from the pre-refiner (or chocolate paste made with powdered sugar from the mixer) and refines it down to 20 micorns (typically). Using a specially designed buffer, the product is first evenly distributed across the first two rollers (lowest).

Price: The price of a chocolate refiner can vary significantly depending on the machine’s size and features. Consider your budget and production needs when selecting a machine.
Even a large variety of rework kişi be processed with the Refiner/Conches following a specific loading procedure. Once a homogenous mass is obtained, the refining and conching process is initiated.

For medium- and large-scale producers there are a wide range of technical options. The varying needs of chocolate producers and the various advantages and disadvantages of the systems on the market make it impossible to give a general recommendation.
The steel belt transport system is specially designed to efficiently transport chocolate flake from the pre-refiner to the five roll refiner and from CHOCOLATE PREPARATION KITCHEN EQUIPMENT the five roll refiner to the conches. Motor power varies by conveyor length.
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.
The key to a good bake is making sure your measurements are precise. Use a baking scale to ensure you’re putting just
