It was just too small and didn't have enough rotational speed nor large enough diameter to generate enough energy to properly refine the sugar and cocoa solids to micron size particles. The chocolate was smoother, but hamiş smooth enough. You could tell it was still homemade.

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.

So one important part of the flow curve is at very low shear. The yield value defines the shear stress, when the mass starts to move. As a minimum shear rate is necessary for the measurement, usually the yield value katışıksız to be extrapolated from the flow curve according to mostra equations, like the ones developed by Casson and Windhab1. Yield values or measurements at low shear stress also have a great practical importance, birli many industrial operations are carried out with masses flowing slowly, for example the equal distribution of still liquid mass in a mould.
The Micron Ball Refinder allows you to do small batch processing of chocolate mass with relatively short cycle times. The unit is equipped with heating and refrigeration to control batch temperatures, and produces chocolate with a fine particle size.
Melangers gönül also act kakım conches, since they can heat and aerate the chocolate, similar to a dedicated conche. However, the tension on the stone wheels must be reduced so that the chocolate doesn’t get over-refined, which means that the particle size of the chocolate is smaller than desired and dirilik contribute to a poor mouthfeel.

The feed mass must have a certain consistency, which is determined by the initial fat content, particle properties and upstream process parameters. Here the particles are ground to their bitiş size, usually below 30µm in order to avoid a sandy texture in the mouth in the final product. A difficulty is to combine the continuous refiners with downstream batch conches. Productivity of both machines strongly decreases if only one refiner is connected to one conch. Therefore usually a number of refiners are connected to a number of conches, which leads to relatively large production lines of several tons per hour. This is also one of the reasons why smaller companies hardly use this technology.
If you’re considering acquiring a panning machine for chocolate, then it’s important to know what to look for. Professional chocolatier Simon Knott shares his experience with chocolate panning machines, and his buying Chocolate DOUBLE TUBE BALL REFINER tips.
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 Swiss company Bühler is market leader in this technology and looks back to a long experience in building and installing complete production lines8.
