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.
Coming from the old refiner conches, where all this happened simultaneously and was hard to control, the majority of later technologies perform the grinding step separately. Only few mill types are able to handle chocolate preparations, as it is initially a very sticky mass, which can transform to a sticky powder during milling, when specific surface of particles increases. The most frequently used devices are plain roller mills (refiners) and stirred ball mills.
Is it possible to produce dark, milk and white mass using identical equipment or even on the same production line?
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 minimum shear rate is necessary for the measurement, usually the yield value saf to be extrapolated from the flow curve according to prototip equations, like the ones developed by Casson and Windhab1. Yield values or measurements at low shear stress also have a great practical importance, as many industrial operations are carried out Chocolate POWDERED SUGAR MILL with masses flowing slowly, for example the equal distribution of still liquid mass in a mould.

The 5-roll fine refiner recieves the chocolate flake from the pre-refiner by the conveyor belt. The chocolate flake is then refined down to 20 metric micron, typically, though finer particle size is also possible.
In this Starting Points video Alchemist John tells you about the 5 Essential pieces of Equipment you need for making modern chocolate at home. #1 might be both really obvious and surprise you. What else would you put on the list?
It takes approximately 40 minutes to heat up. The product yaşama be used as soon as the volume of melted product is above the pump suction outlet, and there is enough to fill the processing system.
Our services and training are designed to keep you up to date on products and technologies, giving you the confidence and experience you need.
It dirilik be beneficial to reach out to fellow chocolatiers or industry professionals for their recommendations and experiences with specific brands or models.
Yes, the product outlet will connect to existing process equipment (with a triclover or your preferred connection). The melter also includes a triclover connection at the rear of the tank for product return to the melter, if required.
She also shares a recipe to ensure the perfect chocolate consistency for your fountain, plus steps for cleaning and how to make chocolate fountain from a kit. In the grand scheme of things, chocolate fountains have …
for white chocolate or milk chocolate with small quantities or high quality cocoa mass. If a stronger treatment is necessary, e.g. for flavour development of dark chocolate, this kişi be achieved by increasing energy input and time. The dry and pasty conching is generally done at low fat contents in order to improve volatilisation. Fat and other ingredients are added then and grinding güç be performed from a buffer mixer by two vertical ball mills with an intermediate cooler. The latter helps to keep temperature of sensitive products below the desired level, e.g. when recipes contain lactose and glass transition during milling must be avoided. The process yaşama be downsized for small production scale, then it consists of a conch with vortex chamber, a ball mill and a pump for circulation.
