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.

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.
We deliver innovative machinery solutions for our customers through collaboration, direct access to our technical team, and willingness to adapt.
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. Birli a asgari shear rate is necessary for the measurement, usually the yield value başmaklık to be extrapolated from the flow curve according to paradigma equations, like the ones developed by Casson and Windhab1. Yield values or measurements at low shear stress also have a great practical importance, bey many industrial operations are carried out with masses flowing slowly, for example the equal distribution of still liquid mass in a mould.
Process air, loaded with volatile and undesired flavour is separated. In the weighing station the recipe is completed by liquid components. The wall scraper of the vessel prepares already a pre-mixture. The exactly composed chocolate mass is discharged in batches into the collecting tank. There it is further mixed and cooled. From there it is continuously pumped through the dynamic flow mixer used for intensive homogenising. After passing a vibrating screen the chocolate mass is ready for further processing.
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.
When shopping for a chocolate melanger, the most important factors to consider are your preferences, budget and specific needs. There are several reputable brands and models available in the market that are highly regarded by chocolatiers and chocolate enthusiasts.
Schmidt continues to operate with a core focus on producing high quality products and solutions for customers within the schedule required.
