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.

Physically, chocolate mass is a suspension of particles in a continuous phase of liquid fat. Downstream when producing bitiş products for the consumer, fat crystallisation is initiated and the mass is forced into the desired shape and solidifies. These steps are derece considered here, although many properties of the final product can be predicted by measurable properties of the still liquid chocolate mass.
During the process the remaining fat and emulsifier are added. Conches are built in various forms and gönül be equipped with one, two or three mixing shafts. More detailed descriptions of the process can be found in1.
We're all familiar with the magic that happens when chocolate meets spice. It's a perfect blend of sweetness, saltiness, and warmth that tantalizes the taste buds. But have you ever experienced the delightful harmony of chai chocolate? Join us bey we get into the world...
The chocolate dough, well refined and rendered its consistency means a shiny looking, homogenous and luscious chocolate.
We provide OEM service. At the same time, life-time after-sales service for our equipment are provided to world wide customer and we are looking forward to your visit.
Faster working time: The machine is faster than a cocoa melanger, which means you sevimli create larger batches of chocolate in less time.
Typical cleaning time. (this incudes both a hot water wash down with detergent and hand cleaning bey required, followed by the time for the machine to dry ready for the next product)
It yaşama be beneficial to reach out to fellow chocolatiers or industry professionals for their recommendations and experiences with specific brands or models.
An early approach to include the removal of volatiles into a recirculating ball mill system was made by DuyvisWiener which included a ‘taste changer; a rotating disk where hot air is blown over the chocolate layer formed by rotation1,15. These devices are still sold for small scale applications. F.B.Lehmann, now part of DuyvisWiener, has a long experience in building thin film evaporators and horizontal ball mills for cocoa processing and had also offered systems for chocolate mass production.
The terms “conche” and “melanger” refer to distinct stages in the chocolate-making process, but they are sometimes used interchangeably. While both conching and melanging contribute to refining chocolate, they serve different purposes and involve different techniques.
for white chocolate or milk chocolate with small quantities or high quality cocoa mass. If a stronger treatment is necessary, e.g. for flavour development of dark chocolate, this dirilik be achieved by increasing energy input and time. The dry and pasty conching is generally done at low fat contents in order to improve volatilisation. Chocolate OIL MELTING –TURBO RENDER Fat and other ingredients are added then and grinding dirilik be performed from a buffer mixer by two vertical ball mills with an intermediate cooler. The latter helps to keep temperature of sensitive products below the desired level, e.g. when recipes contain lactose and glass transition during milling must be avoided. The process emanet be downsized for small production scale, then it consists of a conch with vortex chamber, a ball mill and a pump for circulation.
