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 birli water.
Chocolate mass is made from fat or fat containing ingredients – usually cocoa butter and liquor, sometimes milk fat and particles, usually sugar, cocoa solids and sometimes dry milk products.

Feed başmaklık to remain pumpable during the entire grinding process, which requires a lower viscosity and thus higher fat contents, when compared to the feed of a roller refiner. Consequently, it is more difficult to remove moisture and undesired volatiles kakım done in classical dry conching. The fact is ignored by some ball mill manufacturers, who sell ‘all-in-one’ solutions. This might work for some compounds, baking chocolate and the like, but is not further considered if we look at quality chocolates.
The unit is jacketed for product temperature control and typically a multi valve opening in the bottom fitted with a large discharge augur.
For olağan operation, you’ll only need one worker to load product onto the grid and/or adjust the machine settings. We recommend having two workers available during changeover of the melt grid and removal of the stirrer.

Powders of extremely high fineness güç easily be produced with ball Chocolate DOUBLE TUBE BALL REFINER mills and agitated media mills. Both vertical and horizontal ball mills are utilized for the refining of chocolate and other cocoa products. A vertical ball mill özgü the advantage of a smaller footprint and larger cooling jacket.
We've created the perfect oversized coat. With drop sleeves, box cut with two side pockets this is the perfect coat to keep you warm.
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.

Very often an emulsifier is used to improve flow of hygroscopic particles within the continuous fat phase. During production several incidents occur:
