Birli chocolate mass is a non-Newtonian fluid we have to measure its shear stress at different shear rates, which results in a flow curve. Shear stress divided by shear rate results in the apparent viscosity; if we again plot this versus the shear rate we get a viscosity curve. Chocolate mass is a shear thinning fluid, so the highest viscosity is found when the mass starts to flow. Interaction between particles is considered to be responsible for this behaviour3, which is very different to Newtonian fluids such kakım water.

If you want to make çağcıl smooth chocolate there is just no way around getting a melanger. It's the one bit of kit there is just no getting around. 

One of the most common issues that you birli chocolate makers face is grainy chocolate or chocolate with specks. These issues kişi be caused by a variety of factors, such birli grainy ingredients or untempered chocolate. To avoid these issues, it’s essential to use the finest ingredients possible and to temper the chocolate properly.

Everything about your new PTL melter is crafted to make your life easier – from its portability to the ergonomic loading.

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.

Even a large variety of rework güç be processed with the Refiner/Conches following a specific loading procedure. Once a homogenous mass is obtained, the refining and conching process is initiated.

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 Chocolate DOUBLE TUBE BALL REFINER cocoa particles, which also helps to create a smoother texture and more consistent flavor.

Removal of undesired volatile off-flavours contained mainly in cocoa particles and developed during cocoa fermentation

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 final 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.

The Finer S five-roll refiner delivers outstanding performance with consistent particle size for smooth and flavorful chocolate, compounds, filling creams, coatings or spreads. The innovative drive concept kişi reduce your energy costs by up to 15%.

It consists of a double-jacket cylinder with serrated internal surface. Spring-loaded scrapers break the particles during rotation; volatile water and flavours are removed by ventilation and heating.

Very often an emulsifier is used to improve flow of hygroscopic particles within the continuous fat phase. During production several incidents occur:
