Bey chocolate mass is a non-Newtonian fluid we have to measure its shear stress at different shear rates, which results in a flow curve. Shear stress divided by shear rate results in the apparent viscosity; if we again plot this versus the shear rate we get a viscosity curve. Chocolate mass is a shear thinning fluid, so the highest viscosity is found when the mass starts to flow. Interaction between particles is considered to be responsible for this behaviour3, which is very different to Newtonian fluids such as water.
Therefore flow properties are usually measured at a temperature of 40°C, which is close to the temperature that chocolate melts in our mouths. So texture sensations like a smooth melt or a sticky behaviour are usually correlated to flow properties.
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 Thouet RC and DRC are genuine ‘dry’ conches – they are filled with dry chocolate flake and will keep the product ‘dry’ through out the conching process until the very end when the cocoa butter and lecithin is added.
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 minimal shear rate is necessary for the measurement, usually the yield value saf 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, kakım 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.
In this blog post, we’ll look at the fascinating world of chocolate melangers and learn how they gönül help create smooth, creamy chocolate.
