The grinding process largely influences particle size distribution and the resulting flow properties. Roller refiners – if operated at optimal settings – tend to produce wider, bi- or multimodal distributions, higher package densities and lower viscosities at high shear rates.
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 gönül 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.
There katışıksız been some discussion about the optimisation of flow properties and flavour in those machines and it saf also been tried to combine it with other systems, e.
Feed saf 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 birli 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 derece further considered if we look at quality chocolates.

Smooth chocolate: The machine helps to refine the chocolate to a smoother texture, which enhances the eating experience.
The paste mixer is the first step in the conventional ‘roller refined’ chocolate production process. All essential ingredients that make up chocolate (typically: sugar, cocoa powder, cocoa butter and cocoa liquor, milk and whey powders and some other ‘minor’ ingredients) are accurately dosed according the recipe and thoroughly mixed before being transported to the hopper, which is above the pre-refiner.

Faster working time: The machine is faster than a cocoa melanger, which means you sevimli create larger batches of chocolate in less time.
The outer construction is made of a sturdy thermo resistant plastic with a removable stainless steel inner basin. Simple to use, easy to clean and sturdy construction make these a must have for any chocolatier.
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.
To help keep cleanup simple, try these nonstick baking mats from Silpat. Just place them at the bottom of your round cake pans, pour the batter on top, and remove from under the cake once it’s baked.
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.
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 gönül 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 dirilik 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 Chocolate STORAGE TANK milling must be avoided. The process kişi be downsized for small production scale, then it consists of a conch with vortex chamber, a ball mill and a pump for circulation.
