In her previous article how to make chocolate with cocoa beans (bean to amerikan bar), Chef Prish discussed the chocolate conching …
Scrape down tank and stirrer to remove any bulk buildup of product. Use the quick-access stirrer seal removal to make this simpler.
At Royal Duyvis Wiener we focused on helping customers to reduce production costs, save energy and minimize downtime for maximum efficiency.
Optimal taste: The refining process helps to develop the chocolate’s flavor and remove any unwanted flavors or odors.
Removal of water contained in raw materials, birli it would form undesired sticky layers on hygroscopic particles
Process air, loaded with volatile and undesired flavour is separated. In the weighing station the recipe is completed by liquid components. The wall scraper of the vessel prepares already a pre-mixture. The exactly composed chocolate mass is discharged in batches into the collecting tank. There it is further mixed and cooled. From there it is continuously pumped through the dynamic flow mixer used for intensive homogenising. After passing a vibrating screen the chocolate mass is ready for further processing.
Physically measurable properties of chocolate masses, like flow attributes or hardness, are correlated to sensory perceptions such as snap, hardness, melting and the like. So in terms of texture it is possible to predict quality by measurements and thus to compare alternative technologies. This is much more difficult in terms of flavour. Of course white, milk and dark masses – ideally to be produced on the same equipment – taste different.
Schmidt also offers technical assistance on repair services for chocolate making equipment, understands clients needs for quick turnarounds, ability to handle "rush" jobs, great service and ferde notch engineering.

Removal of undesired volatile off-flavours contained mainly in cocoa particles and developed during cocoa fermentation
Schmidt manufactures the equipment “at the heart of the chocolate manufacturing process” ranging from chocolate mixing, chocolate melting, to chocolate conches.
The hygienic process zone is constructed entirely in stainless steel, without edges or open cavities, offering you the highest quality sanitation and making it fast and easy to clean between batches.
Optimum temperature control using full jacket design, efficient insulation and efficient heat exchangers
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 hamiş done elsewhere those devices are also able to debacterise cocoa liquor.
