As 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 birli water.
This pale yellow vegetable fat extracted from cocoa beans is renowned for its unique aroma reminiscent of chocolate and its smooth texture. Cocoa butter is an important component in chocolate-making, and it

Nevertheless also here one refiner would need several hours to fill a large 6-t-conch, which hayat only be solved by always having one machine idle or by using at least two smaller conches. For very small scale or test production the company also builds a tayyareci scale 5RR with 50cm rolls and 3-rollers.
So one important part of the flow curve is at very low shear. The yield value defines the shear stress, when the mass starts to move. Bey a minimal shear rate is necessary for the measurement, usually the yield value has to be extrapolated from the flow curve according to sistem equations, like the ones developed by Casson and Windhab1. Yield values or measurements at low shear stress also have a great practical importance, as many industrial operations are carried out with masses flowing slowly, for example Chocolate TEMPERING MACHINE the equal distribution of still liquid mass in a mould.

The paste mixer is the first step in the conventional ‘roller refined’ chocolate production process. All essential ingredients that make up chocolate (typically: sugar, cocoa powder, cocoa butter and cocoa liquor, milk and whey powders and some other ‘minor’ ingredients) are accurately dosed according the recipe and thoroughly mixed before being transported to the hopper, which is above the pre-refiner.
Choosing the right chocolate refiner dirilik be difficult. The right choice depends on several factors, including the size of your chocolate processing facility, your budget, and your production needs. Some key considerations to keep in mind when selecting a chocolate refiner include:

A double-acting vane pump recirculates the product in association with the grinding phase, but also allows the machine to be emptied at the end of the cycle.
The goal of the melanger is to achieve a homogeneous mixture and a desirable texture in the chocolate.
