The grinding process largely influences particle size distribution and the resulting flow properties. Roller refiners – if operated at optimal settings – tend to produce wider, bi- or multimodal distributions, higher package densities and lower viscosities at high shear rates.
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.

The Thouet dry conche from the Royal Duyvis Wiener group is used to lower the moisture content of the chocolate and with that improve the rheological properties. Also, undesierable flavor profiles yaşama be removed and other flavor profiles yaşama be created or accentuated.
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 minimum shear rate is necessary for the measurement, usually the yield value has to be extrapolated from the flow curve according to örnek 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 titrem. The CHOCOLATE PREPARATION KITCHEN EQUIPMENT examples below are based on melting chips/buttons with typical coating characteristics.

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.
With a bit of patience and the right equipment, you emanet create fantastic chocolate with optimal taste and a smooth texture that will impress your customers and friends alike. So, whether you’re a seasoned cook or professional chocolate producer, consider investing in a chocolate refiner to take your chocolate creations to the next level.
Frequently the other operations are performed within a long-term kneading process called conching. Very long conching times are still recommended and associated with good quality, although the devices require high capital investment. One of the major progresses established in the last 30 years was to move cocoa flavour treatment out of the conch into the upstream cocoa processing. Thin film evaporators were developed in order to remove undesired volatiles and water; if this is not done elsewhere those devices are also able to debacterise cocoa liquor.
