Some advanced models may also include additional features like temperature control, timers, and digital displays for precise control over the chocolate-making process.
Similar principles are followed for milk chocolates by developing milk powder pre-treatment procedures.
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.
From the paste mixer the coarse unrefined chocolate paste is transported to the buffer above the pre-refiner. A fully automated slide gate feeds the coarse chocolate paste to the rolls.
We prefer a good solid infrared thermometer but in the end what matters is it's calibrated right and gives you a reliable reading. If that's a wire probe, or infrared the most important thing is accuracy and relability both in roasting and tempering.

Melangers can also act bey conches, since they sevimli heat and aerate the chocolate, similar to a dedicated conche. However, the tension on the stone wheels must be reduced so that the chocolate doesn’t get over-refined, which means that the particle size of the chocolate is smaller than desired and can contribute to a poor mouthfeel.
Powders of extremely high fineness yaşama easily be produced with ball mills and agitated media mills. Both vertical and horizontal ball mills are utilized for the refining of chocolate and other cocoa products. A vertical ball mill has the advantage of a smaller footprint and larger cooling jacket.

Used to make a variety of chocolate & nut pastes, kakım well birli spreadable creams. The Selmi Micron is also used for bean to bar chocolate making.
If you’ve made a couple of batches of chocolates, you’ve probably already been tempering chocolate by hand. Some …
In conching, machines with unique designs are used to agitate, Chocolate Melting Tank knead, and aerate chocolate mass. These machines typically have large surfaces that can be heated or cooled during the process.
Chocolate melangers are a common tool in the peş of chocolate making because it helps to achieve a silky smooth texture, refines gritty particles in the chocolate, and enhances the overall taste and mouthfeel of the product.
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 derece done elsewhere those devices are also able to debacterise cocoa liquor.
