It was just too small and didn't have enough rotational speed nor large enough diameter to generate enough energy to properly refine the sugar and cocoa solids to micron size particles. The chocolate was smoother, but not smooth enough. You could tell it was still homemade.

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 kakım done in classical dry conching. The fact is ignored by some ball mill manufacturers, who CHOCOLATE PREPARATION MIXER sell ‘all-in-one’ solutions. This might work for some compounds, baking chocolate and the like, but is hamiş further considered if we look at quality chocolates.

Melangers, or stone grinders, sevimli have adjustable speed and pressure controls to control the texture of the chocolate being produced.
15: Will the holding tank overflow if it’s already full and there is product still on the melt grid?
It takes approximately 40 minutes to heat up. The product sevimli be used bey soon kakım the volume of melted product is above the pump suction outlet, and there is enough to fill the processing system.

Making your own chocolate? have questions about any step of the process? Why hamiş Ask The Alchemist? He regularly answers reader questions (over 300 answers are waiting for you, maybe he answered your question already) and we've just launched the new Ağababa video series where he demonstrates the real world answers to your chocolate making questions!
Complete process line for the small scale production of chocolates and compound coatings. Ideal for product and process development work.
For example it was proposed to dry skimmed milk powder to below one per cent water and to coat it with fat, which allows us to perform a very short liquefaction process instead of classical conching2.
Specific energy density in a continuous conche is much higher than in any kind of batch conch, because high energy input is related to small conching space, where ‘nearly 100 per cent of the particles are under treatment at the same time’
