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 kakım water.

Because of the pressure and the speed differential between the rolls, the product is picked up and refined more and more between each susequent seki of rolls. The five roll refiner saf four (4) refining steps, each roll saf a different speeds. Pressures are controlled kakım well.
Optimal taste: The refining process helps to develop the chocolate’s flavor and remove any unwanted flavors or odors.
The unit is jacketed for product temperature control and typically a multi valve opening in the bottom fitted with a large discharge augur.
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.

The refining process involves a combination of grinding, heating, and mixing that helps to develop the great chocolate’s flavor and texture. The machine is also used to reduce the size of the cocoa particles, which also helps to create a smoother texture and more consistent flavor.
The more common case is that good quality is desired – usually correlated to low viscosity – at lowest possible fat contents. If planning a chocolate mass line, one of the major decisions will be which the most important part of the flow curve is.
How do we guarantee you’ll have excellent ROI? By solving your efficiency blocks with customized designs and over 30 years of experience. Here are just some of the unique features built into each of our machines:
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 birli:
An improved dry run camera system Chocolate HORIZONTAL BALL REFINER with a larger (30 cm) monitoring range helps to avoid roll dry runs. Shear pins are designed to prevent major damage caused by foreign bodies in the roll gap and Finer S offers you pressure monitoring for hydraulics, water and air.
After building highly reputed conches, batch and in-line mixers for a long time, Lipp Mischtechnik katışıksız now developed a complete chocolate line called Eco2choc® (Figure 6). It is based on the ‘coarse conching’ processing concept. Development and optimisation are described in7; research başmaklık also shown that milk chocolate of good flow properties and taste birey be produced. One key element is a high shear head or vortex chamber built into the kneading zone of the conch. It intensifies mass and energy alma, but also reduces particle size of crystal sugar to approximately 300μm – thus no pre-grinding device is necessary. Coarse conching time emanet be short if just drying is needed, e.g.
