Also the taste can be largely influenced by choosing the right ingredients. In those cases, processing technology becomes less important and most of the systems on the market will be able to produce the desired quality.
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.
Because of the pressure and the speed differential between the rolls, the product is picked up and refined more and more between each susequent set of rolls. The five roll refiner has four (4) refining steps, each roll özgü a different speeds. Pressures are controlled bey well.

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 mostra 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.
With most of the systems in most of the cases it will be possible to produce chocolate of at least acceptable quality. Fine-tuning and bitiş choice katışıksız to be made in every single case; it is always both recipe and process that influences final quality and there is no ‘out-of-the-box’ solution. So the best possible advice might be:
Vulcanotec is knows for its designes which allow the manufacturers to clean amd maintain the machines for a longer period of time.
Even a large variety of rework birey be processed with the Refiner/Conches following a specific loading procedure. Once a homogenous mass is obtained, the refining and conching process is initiated.
For chocolate and chocolate coating production, Kocotek specializes CHOCOLATE PREPARATION MIXER in traditional five-roll refining combined with dry conching, kakım well as, the modern ball mill production technology, combined with either a continuous ‘wet’ conche or a batch ‘dry’ conche.

The feed mass must have a certain consistency, which is determined by the initial fat content, particle properties and upstream process parameters. Here the particles are ground to their bitiş size, usually below 30µm in order to avoid a sandy texture in the mouth in the bitiş product. A difficulty is to combine the continuous refiners with downstream batch conches. Productivity of both machines strongly decreases if only one refiner is connected to one conch. Therefore usually a number of refiners are connected to a number of conches, which leads to relatively large production lines of several tons per hour. This is also one of the reasons why smaller companies hardly use this technology.
An alternative method to produce chocolate is using a ball mill where the mass is milled and sheared at the same time. Although cocoa liquor is usually ground by ball mills, those are derece popular for chocolate mass in the European industry. Nevertheless those systems are commonly used worldwide. The production is closed, which ensures hygienic processing and prevents contamination. Industrial-scale ball mills work continuously.
