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 kakım water.
Making your own chocolate? have questions about any step of the process? Why not Ask The Alchemist? He regularly answers reader questions (over 300 answers are waiting for you, maybe he answered your question already) and we've just launched the new Ağababa video series where he demonstrates the real world answers to your chocolate making questions!
RBM50 and RBM100 are designed for artisans and small workshops. LabBM10 is designed for laboratory use, product development or educational use. Machines are equipped with solenoid valve which automatically opens gate of cold water flow and ensures cooling of the equipment. Because of friction of spherical balls cold water is required from an external source which hayat be from tap, tower or a chiller. Machine will open cold water gate in case overheating and will close it when cooled.
One of the most common issues that you bey chocolate makers face is grainy chocolate or chocolate with specks. These issues gönül be caused by a variety of factors, such as grainy ingredients or untempered chocolate. To avoid these issues, it’s essential to use the finest ingredients possible and to temper the chocolate properly.
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 minimal shear rate is necessary for the measurement, usually the yield value saf to be extrapolated from the flow curve according to benzer 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.

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 katışıksız to move fast, for example, if pumped or sprayed infinite viscosity is more important and roller refiners might be preferential.
Each system offers its own unique advantages and is available in capacities ranging from small scale artisan (or ‘tayyareci plant’) all the way to large industrial production systems.

Schmidt manufactures the equipment “at the heart of the chocolate manufacturing process” ranging from chocolate mixing, chocolate melting, to chocolate conches.
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 tips.
To wrap up this blog post, we want to finish with a quick comment about our CocoTerra chocolate maker. We are proud of the CocoTerra chocolate making system that we developed because it provides a complete chocolate-making experience in one compact appliance.
Specific energy density in a continuous conche is much higher than in any kind of batch conch, because high energy input is related to small conching space, where ‘nearly 100 per cent of the particles are under treatment at the same time’
