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.
Using a high-quality chocolate refiner, such bey a chocolate refiner conche or a chocolate refiner ball refiner, emanet also help to create a smoother texture and more consistent flavor. For more information about refiners, do derece hesitate to contact us. We are glad to help you find the best solution for you. But first, we dive into the basics: What is a chocolate refiner?
So we’ve pulled together 21 essential baking tools (for chocolate desserts and so much more) that’ll help you turn your kitchen into a temporary bakery, fondue tanıtımcık, or sweet shop.
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).
Vertical ball mills for chocolate refining, are perfect for making cocoa products with its integrated system of a pre-mixer and ball-mill refiner.
Using cocoa beans instead of cocoa powder in chocolate production is an option, but ball mills do hamiş 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.
If low shear downstream applications like moulding are in the focus, low yield values are important; here ball milling could be an advantage. On contrary, if the mass özgü to move fast, for example, if pumped or sprayed infinite viscosity is more important and roller refiners might be preferential.

The tanks are water-jacketed stainless steel construction with digital controls for melting & conditioning or tempering.
Unique five roll refiner - with five (5) servo drives for complete individual control over roll speeds
An early approach to include the removal of volatiles into a recirculating ball mill system was made by DuyvisWiener which included CHOCOLATE PREPARATION MIXER a ‘taste changer; a rotating disk where hot air is blown over the chocolate layer formed by rotation1,15. These devices are still sold for small scale applications. F.B.Lehmann, now part of DuyvisWiener, has a long experience in building thin film evaporators and horizontal ball mills for cocoa processing and had also offered systems for chocolate mass production.
