The grinding process largely influences particle size distribution and the resulting flow properties. Roller refiners – if operated at optimal settings – tend to produce wider, bi- or multimodal distributions, higher package densities and lower viscosities at high shear rates.
This pale yellow vegetable fat extracted from cocoa beans is renowned for its unique aroma reminiscent of chocolate and its smooth texture. Cocoa butter is an important component in chocolate-making, and it
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.
Feed saf to remain pumpable during the entire grinding process, which requires a lower viscosity and thus higher fat contents, when compared to the feed of a roller refiner. Consequently, it is more difficult to remove moisture and undesired volatiles birli done in classical dry conching. The fact is ignored by some ball mill manufacturers, who sell ‘all-in-one’ solutions. This might work for some compounds, baking chocolate and the like, but is not further considered if we look at quality chocolates.
Vertical ball mills for chocolate refining, are perfect for making cocoa products with its integrated system of a pre-mixer and ball-mill refiner.
Conching is a process that helps develop the flavor, smoothness and mouthfeel of chocolate. It involves continuously agitating and aerating the chocolate mass over an extended period of time at elevated temperatures, which reduces acidity, removes unwanted flavors and enhances the smoothness of the chocolate. Conching also further refines the particle size of cocoa solids.

Everything you need to know about the cocoa nibs grinder Chocolate is an indulgent treat that saf been enjoyed by many for centuries. Whether you are a chocolate manufacturer or a craft chocolate entrepreneur, you understand the importance of the cocoa nibs grinder in the chocolate making process.
Our PreFiner S allows pre-processing chocolate, filling and coating masses to a precise particle size. Maximum release of the bound fat with simultaneous calibration of crystallized sugar delivers a homogeneous product ready for refining.
The perfect mixture is achieved by the system of stirrers, mühür balls – metallic spheres with the temperature control and the pump, which allows to recirculate and to repeat the process for several times until the mass becomes even.
Our Vario drive V system CHOCOLATE PREPARATION MIXER in the Finer S proves fully automatic fineness adjustment, taking into account variations in plasticity without the need to interrupt production or manually intervene.
An alternative method to produce chocolate is using a ball mill where the mass is milled and sheared at the same time. Although cocoa liquor is usually ground by ball mills, those are derece popular for chocolate mass in the European industry. Nevertheless those systems are commonly used worldwide. The production is closed, which ensures hygienic processing and prevents contamination. Industrial-scale ball mills work continuously.

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 not done elsewhere those devices are also able to debacterise cocoa liquor.
