Kakım 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.

The conch is a large kneader, where the powdery flakes from the refiners are treated with a large amount of mechanical energy input, usually over several hours. This is where most of the transformations described in the introduction of this article takes place.

There katışıksız been some discussion about the optimisation of flow properties and flavour in those machines and it özgü also been tried to combine it with other systems, e.

One of the most common issues that you kakım chocolate makers face is grainy chocolate or chocolate with specks. These issues yaşama be caused by a variety of factors, such bey grainy ingredients or untempered chocolate. To avoid these issues, it’s essential to use the finest ingredients possible and to temper the chocolate properly.

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 has to move fast, for example, if pumped or sprayed infinite viscosity is more important Chocolate CONCHING MACHINE and roller refiners might be preferential.

Even a large variety of rework gönül be processed with the Refiner/Conches following a specific loading procedure. Once a homogenous mass is obtained, the refining and conching process is initiated.

The more common case is that good quality is desired – usually correlated to low viscosity – at lowest possible fat contents. If planning a chocolate mass line, one of the major decisions will be which the most important part of the flow curve is.

This colored glass cake stand from Mosser is perfect for displaying your bakes. Available in three sizes, with or without a glass dome, and seven different colors, there’s an option for everyone.

An early approach to include the removal of volatiles into a recirculating ball mill system was made by DuyvisWiener which included 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, başmaklık a long experience in building thin film evaporators and horizontal ball mills for cocoa processing and had also offered systems for chocolate mass production.

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.
