That includes chocolate producers, industrial chocolate manufacturers or bulk handlers of processed chocolate for bakeries, nutrition pas makers.

The sturdy design and the vast Bühler roller know-how give you precise and consistent particle sizes in your bitiş refining process. The targeted particle size with a narrow particle-size distribution generates the mouthfeel you want and simplifies flow properties for consistent end products.

The process is shown in Figure 4. Refiner flakes are transferred into the feed hopper, its filling level controls speed of the feed screw and compensates supply variations. While some cocoa butter is added, the screw feeds the pasting columns. It is equipped with adjustable baffles and shearing wings; the flakes are subjected to intensive mechanical stress. During this process the mass changes from its dry state (dry conching) to a tough plastic state. Cleaned conditioned air is supplied by fan. After finally adding lecithin it leaves the pasting column in flowable consistency. The mass is passed to an intermediate tank whose stirrers and wall scrapers keep the chocolate in motion to stabilise the process of the structural changes after the adding of lecithin.

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).

Genuine dry conching allows for more efficient evaporation of the moisture and while also benefitting from the high sheer forces from the specially designed conching elements.

Using cocoa beans instead of cocoa powder in chocolate production is an option, but ball mills do derece provide efficient results in grinding raw materials thicker than 1.5 - 2mm, so cocoa beans should be pre-grinded into a thick paste in an impact mill or beater blade mill.

The paste mixer is the first step in the conventional Chocolate POWDERED SUGAR MILL ‘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.

Recently, Bühler seems to have followed a similar strategy. For compounds the company offers a ball mill solution called SmartChoc™ with a horizontal ball mill and a shear mixer.

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.

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