A lot of time başmaklık passed since the first refiner conches were built to make chocolate. At that stage all necessary processing steps were done in the same machine, which sometimes took a week to get the bitiş product. This paper is derece intended to summarise all the technical developments since then as such information is available in textbooks1.
Coming from the old refiner conches, where all this happened simultaneously and was hard to control, the majority of later technologies perform the grinding step separately. Only few mill types are able to handle chocolate preparations, birli it is initially a very sticky mass, which birey transform to a sticky powder during milling, when specific surface of particles increases. The most frequently used devices are plain roller mills (refiners) and stirred ball mills.
Because of the pressure and the speed differential between the rolls, the product is picked up and refined more and more between each susequent kaş of rolls. The five roll refiner saf four (4) refining steps, each roll katışıksız a different speeds. Pressures are controlled kakım well.
It dirilik be made entirely of stainless or black material. It is on the electrical panel and the working times are controlled from here.

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.

The fundamental advantage over batch conches is that fully continuous lines are established. On the other hand side a minimum throughput of 1,250kg/h is required over a longer time, so the process is not suitable for frequent recipe change or smaller companies.

Typical cleaning time. (this incudes both a hot water wash down with detergent and hand cleaning as required, followed by the time for the machine to dry ready for the next product)
This is possible through pre-drying refiner flakes5 or milk powder6. Downstream, the liquefaction emanet be done in a very rapid batch process or continuously using a high-speed in-line mixer14.
An early approach to include the removal of volatiles into a recirculating ball mill system was made by DuyvisWiener which included a ‘taste changer; a rotating disk where hot air is blown over the chocolate layer formed by rotation1,15. These devices are still sold for small scale applications. F.B.Lehmann, now part of DuyvisWiener, özgü a long experience in building thin film evaporators and horizontal ball mills for cocoa processing and had also offered systems for chocolate mass production.
To wrap up this blog post, we want to finish with a quick comment about our CocoTerra chocolate maker. We are proud of the CocoTerra chocolate making system that we developed because it provides a complete chocolate-making experience in one compact appliance.
