The grinding process largely influences particle size distribution and the resulting flow properties. Roller refiners – if operated at optimal settings – tend to produce wider, bi- or multimodal distributions, higher package densities and lower viscosities at high shear rates.
Therefore flow properties are usually measured at a temperature of 40°C, which is close to the temperature that chocolate melts in our mouths. So texture sensations like a smooth melt or a sticky behaviour are usually correlated to flow properties.

5.It is easy to operate this machine.It is equipped with full set of imported fully automatic PLC. It only takes a few days training even for new staff to get all the operation knowledge. Only 1-2 staff/shift for each equipment is needed.
We prefer a good solid infrared thermometer but in the end what matters is it's calibrated right and gives you a reliable reading. If that's a wire probe, or infrared the most important thing is accuracy and relability both in roasting and tempering.

Melangers also come in a variety of sizes, some that fit on a kitchen counter and others that are using for commercial production.
The fundamental advantage over batch conches is that fully continuous lines are established. On the other hand side a minimal throughput of 1,250kg/h is required over a longer time, so the process is hamiş suitable for frequent recipe change or smaller companies.
Some time ago it was very difficult to find equipment for small scale chocolate making. This has changed; now there are a number of ball mill-based systems on the market and also smaller scale roll refiners have been developed.
Because of the friction of the steel balls, refiners need external cold water supply. It is possible to use tap or tower water CHOCOLATE PREPARATION MIXER for cooling but we suggest using a chiller for the cooling purpose.
After that the mass is liquefied by adding cocoa butter and then ground by circulation through a horizontal ball mill. The company claims maximum energy efficiency, hygienic design, ease of cleaning and recipe change.

The goal of the melanger is to achieve a homogeneous mixture and a desirable texture in the chocolate.
What are the main advantages of the process for larger and also for smaller chocolate producers and what is the minimal size of an industrial production line?
