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 birli water.

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.

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. Bey a asgari shear rate is necessary for the measurement, usually the yield value has to be extrapolated from the flow curve according to model 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.
Use the table below to estimate possible melt rates of chips or buttons and blocks – from small (10lbs) to one ton. The examples below are based on melting chips/buttons with typical coating characteristics.
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.
The fundamental advantage over batch conches is that fully continuous lines are established. On the other hand side a minimum throughput of 1,250kg/h is required over a longer time, so the process is not suitable for frequent recipe change or smaller companies.
Ball mill grinding process Ball mill grinding is a critical process in the chocolate production industry. It involves crushing
Our chocolate equipment have been popular in the food industry. At the same time, the products produced by our equipment are also in the forefront of the candy industry birli well.
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.
So in practice, chocolate makers will always have to negotiate individually with suppliers. This paper will provide an introduction Chocolate CONCHING MACHINE to the possibilities on the market.
For example it was proposed to dry skimmed milk powder to below one per cent water and to coat it with fat, which allows us to perform a very short liquefaction process instead of classical conching2.
