Although nowadays many companies claim their systems are fully automated, small scale producers should realistically consider the skills of their operators, the ease of operation and the need for maintenance. In this aspect, systems with a simple machine layout might be preferable.

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

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.

Typical cleaning time. (this incudes both a hot water wash down with detergent and hand cleaning bey required, followed by the time for the machine to dry ready for the next product)

For medium- and large-scale producers there are a wide range of technical options. The varying needs of chocolate producers and the various advantages and disadvantages of the systems on the market make it impossible to give a general recommendation.

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 not 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.

It provides the mixing of the necessary products to prepare the chocolate dough. It is the first step in making chocolate dough. In this part, the chocolate ensures homogeneous mixing.

The Swiss company Bühler is market leader in this technology Chocolate Melting Tank and looks back to a long experience in building and installing complete production lines8.
