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, as it is initially a very sticky mass, which yaşama 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.
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.

If you’re going to be dealing with any sort of dough—pie, pain au chocolat, or cookie, to name a few—you’ll want a bench scraper to help slice it up (and then scrape off the counter) with ease.
McCarter tanks, mixers, melters and other chocolate making equipment continue to earn a high quality reputation within the industry due to Schmidt’s production skill and quality control.
This very unique machine resurrects the traditional method of conching and grinding at the same time, kakım we know it from the Lindt longitudinal conch1.
Although both machines are used for chocolate making, there are some significant differences between a chocolate refiner and Chocolate OIL MELTING –TURBO RENDER a cocoa melanger. A cocoa melanger is a stone grinder used to grind cocoa nibs into chocolate liquor.
The ball refiner by Pomati group srl is designed for the production of spreadable creams, anhydrous pates for ice creams, pralinate products and cream sweets.
YS/B 500 with unique design, distinctive workmanship and advanced technology provides maximum product output in minimal time and works noiselessly.
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.
Yes, the product outlet will connect to existing process equipment (with a triclover or your preferred connection). The melter also includes a triclover connection at the rear of the tank for product return to the melter, if required.
If cocoa butter is replaced by another fat, the product is usually called compound and not chocolate. Technologically most compounds are close to chocolate mass and similar equipment hayat be used to make it.
In this article, Chef Prish explains the different styles of machines used to grind and conche chocolate at home. She discusses the features, pros and cons of stone melangers, wet grinders, roller mills and more.
