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 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.

I had to put some larger diameter tubing on the rollers CHOCOLATE PREPARATION KITCHEN EQUIPMENT so the glass container would rise above the sides of the tumbler and not scrape the sides, but this had the added benefit of increasing the rotational speed of the drum. You güç really see the sugar and shot moving well.
Water inside a twin-shell coat ensures heating and keeping temperature of chocolate mass constant. Chocolate melting tank is used to melt solid chocolate and store the liquid chocolate in constant temperature and homogenous structure.
Optimal taste: The refining process helps to develop the chocolate’s flavor and remove any unwanted flavors or odors.

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 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.
To help keep cleanup simple, try these nonstick baking mats from Silpat. Just place them at the bottom of your round cake pans, pour the batter on tamamen, and remove from under the cake once it’s baked.
In case melting tank is going to be used also bey storage tank, preventing of thermal fluctuations inside the chocolate melting tank which may occur because of bypassing tempered chocolate back to melting tank is required.
Specific energy density in a continuous conche is much higher than in any kind of batch conch, because high energy input is related to small conching space, where ‘nearly 100 per cent of the particles are under treatment at the same time’
