Unfortunately the very popular Petzomat is derece built any more, but alternatives from other companies are available. Nowadays chocolate producers kişi strongly reduce conching times if they insist on using pre-treated cocoa liquor of high flavour quality. Untreated cocoa is also still used, which then requires extra conching, like in former times.
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 grup of rolls. The five roll refiner özgü four (4) refining steps, each roll başmaklık a different speeds. Pressures are controlled kakım well.

I purchased two rock tumblers a couple of months ago. Within a day the larger one had stopped working so I was left to experiment with the smaller one. Well, it did the job somewhat, but not fully.
Although both machines are used for chocolate making, there are some significant differences between a chocolate refiner and a cocoa melanger. A cocoa melanger is a stone grinder used to grind cocoa nibs into chocolate liquor.
The refining process involves a combination of grinding, heating, and mixing that helps to develop the great chocolate’s flavor and texture. The machine is also used to reduce the size of the cocoa particles, which also helps to create a smoother texture and more consistent flavor.
Chocolate melting tanks are designed to dissolve, melt and maintain the temperature of chocolate. They help to maintain chocolate in a tempered state using a thermostat.
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 final Chocolate SINGLE TUBE BALL REFINER 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.
