Kakım chocolate mass is a non-Newtonian fluid we have to measure its shear stress at different shear rates, which results in a flow curve. Shear stress divided by shear rate results in the apparent viscosity; if we again plot this versus the shear rate we get a viscosity curve. Chocolate mass is a shear thinning fluid, so the highest viscosity is found when the mass starts to flow. Interaction between particles is considered to be responsible for this behaviour3, which is very different to Newtonian fluids such bey water.
The sturdy design and the vast Bühler roller know-how give you precise and consistent particle sizes in your bitiş refining process. The targeted particle size with a narrow particle-size distribution generates the mouthfeel you want and simplifies flow properties for consistent end products.

Unless you're buying roasted nibs a roaster is vital. You may know we don't really advocate for Raw Chocolate and as such you need to roast your beans both for health and safety but also for flavor. Roasting deeply affects the end taste of your bars.
Genuine dry conching allows for more efficient evaporation of the moisture and while also benefitting from the high sheer forces from the specially designed conching elements.

Physically measurable properties of chocolate masses, like flow attributes or hardness, are correlated to sensory perceptions such as snap, hardness, melting and the like. So in terms of texture it is possible to predict quality by measurements and thus to compare alternative technologies. This is much more difficult in terms of flavour. Of course white, milk and dark masses – ideally to be produced on the same equipment – taste different.
Although both machines are used for chocolate making, there are some significant differences between a chocolate refiner and a cocoa melanger. A cocoa melanger is a stone grinder used to grind cocoa nibs into chocolate liquor.
We've created the CHOCOLATE PREPARATION MIXER perfect oversized coat. With drop sleeves, box cut with two side pockets this is the perfect coat to keep you warm.
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)

In conching, machines with unique designs are used to agitate, knead, and aerate chocolate mass. These machines typically have large surfaces that birey be heated or cooled during the process.
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 minimum size of an industrial production line?
