Chocolate mass is made from fat or fat containing ingredients – usually cocoa butter and liquor, sometimes milk fat and particles, usually sugar, cocoa solids and sometimes dry milk products.
If you want to make çağcıl smooth chocolate there is just no way around getting a melanger. It's the one bit of kit there is just no getting around.
One of the first things a chocolate producer başmaklık to consider are the influences of recipe, ingredients and particles on chocolate mass properties as discussed above. First of all, if raw material cost is less important, e.g. in the premium segment or for making compounds, it is always quite simple to increase the fat content in the recipe in order to achieve the desired mass properties.
Oh, and someone asked about the glass. I have taped up the outside to increase friction and contain breakage should it happen.
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.
If low shear downstream applications like moulding are in the focus, low yield values are important; here ball milling could be an advantage. On contrary, if the mass katışıksız to move fast, for example, if pumped or sprayed infinite viscosity is more important and roller refiners might be preferential.
We provide OEM service. At the same time, life-time after-sales Chocolate STORAGE TANK service for our equipment are provided to world wide customer and we are looking forward to your visit.
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.
Because of the friction of the steel balls, refiners need external cold water supply. It is possible to use tap or tower water for cooling but we suggest using a chiller for the cooling purpose.

After some initial information on chocolate mass properties the systems available on the market will be introduced. For that purpose information was obtained from various manufacturers, followed by questions and discussions on aspects such kakım:
After those, particle size distribution and particle package density are also important. Equal or monomodal particle sizes would create large voids filled with fat. With a bi- or multimodal distribution it is possible to replace this trapped fat by the appropriate size solid particles, which also helps larger particles to slip past each other when the suspension is moved.
This means there are a lot more varieties in each category up to the specific ‘house tastes’ that are aimed at by individual chocolate manufacturers. So at the end of the day it is generally impossible to define the flavour for high quality and to compare and identify equipment to achieve it. If considering processing alternatives it will always be necessary to adapt recipes and technology to each other in order to get the desired result.
