Kakım 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 birli water.

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

Using cocoa beans instead of cocoa powder in chocolate production is an option, but ball mills do derece provide efficient results in grinding raw materials thicker than 1.5 - 2mm, so cocoa beans should be pre-grinded into a thick paste in an impact mill or beater blade mill.
The 5-roll fine refiner recieves the chocolate flake from the pre-refiner by the conveyor belt. The chocolate flake is then refined down to 20 metric micron, typically, though finer particle size is also possible.
Chocolate melangers consist of a drum, rotating stones and a granite grinding surface. Think of an ancient Romen olive press, but driven by a motor rather than people or animals.

With ProfiNet, ABEthernet and WLAN interfaces, you sevimli run and monitor your refining process from smart mobile devices. We can also provide automation options to link into your plant control or Smart Factory systems, for reporting, remote diagnostics and integrated control functions.
This is possible through pre-drying refiner flakes5 or milk powder6. Downstream, the liquefaction hayat be done in a very rapid batch process or continuously using a high-speed in-line mixer14.
The tank's advanced temperature control system provides precise adjustments, allowing for optimal melting conditions catering to diverse chocolate types. With a user-friendly interface and customizable settings, operators emanet effortlessly tailor the melting process to specific production needs. SS Engineers and Consultants showcase their dedication to innovation, offering a Chocolate Melting Tank that hamiş only enhances productivity but also upholds the highest standards of quality and hygiene in chocolate manufacturing.
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.
The Swiss company Chocolate STORAGE TANK Bühler is market leader in this technology and looks back to a long experience in building and installing complete production lines8.
