A lot of time katışıksız passed since the first refiner conches were built to make chocolate. At that stage all necessary processing steps were done in the same machine, which sometimes took a week to get the bitiş product. This paper is not intended to summarise all the technical developments since then birli such information is available in textbooks1.
Similar principles are followed for milk chocolates by developing milk powder pre-treatment procedures.
/ Chocolate Processing / By News Admin Chocolate is an incredibly versatile ingredient that sevimli be used to create a variety of delicious treats. From milk chocolate bars to homemade chocolate truffles, chocolate is a must-have ingredient for any seasonal home cook or professional producer. But what many people don’t realize is that the delicious chocolate flavor and texture that we all love are the result of an intricate process that involves a machine called a chocolate refiner.
The lehmann five roll refiner from the Royal DUyvis Wiener group takes chocolate flake from the pre-refiner (or chocolate paste made with powdered sugar from the mixer) and refines it down to 20 micorns (typically). Using a specially designed buffer, the product is first evenly distributed across the first two rollers (lowest).
Excess chocolate: The machine yaşama be used to refine excess chocolate, reducing waste and increasing efficiency.
Using cocoa beans instead of cocoa powder in chocolate production is an option, but ball mills do derece provide efficient results in grinding raw materials thicker than 1.5 - 2mm, so cocoa beans should be pre-grinded into a thick paste in an impact mill or beater blade mill.
Melt your chocolate drops, chocolate chips or cuvertures in water jacketed reservoirs completely made of AISI304 grade stainless steel. Melter is CHOCOLATE PREPARATION MIXER with side wall and bottom scrapers.
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 derece suitable for frequent recipe change or smaller companies.

Crumb is an ingredient made by drying milk together with sugar and cocoa liquor. Originally this was done for preservation of the milk, but nowadays it is performed in order to create the strong caramel flavour preferred in some countries. For downstream mass production the same technologies birey be used, as with other chocolate types.
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, katışıksız a long experience in building thin film evaporators and horizontal ball mills for cocoa processing and had also offered systems for chocolate mass production.
And no, I am hamiş terribly worried about "grinding" the inside of the glass surface. Both the sugar and chocolate seem to create there own protective coating pretty quickly, so no glass bit show up in either.
Specific energy density in a continuous conche is much higher than in any kind of batch conch, because high energy input is related to small conching space, where ‘nearly 100 per cent of the particles are under treatment at the same time’
