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 derece intended to summarise all the technical developments since then bey such information is available in textbooks1.
Equipment on a pilot plant scale for is used for testing and experimenting with the process and product development of chocolates and compound coatings.
The process is shown in Figure 4. Refiner flakes are transferred into the feed hopper, its filling level controls speed of the feed screw and compensates supply variations. While some cocoa butter is added, the screw feeds the pasting columns. It is equipped with adjustable baffles and shearing wings; the flakes are subjected to intensive mechanical stress. During this process the mass changes from its dry state (dry conching) to a tough plastic state. Cleaned conditioned air is supplied by fan. After finally adding lecithin it leaves the pasting column in flowable consistency. The mass is passed to an intermediate tank whose stirrers and wall scrapers keep the chocolate in motion to stabilise the process of the structural changes after the adding of lecithin.

Conches are stainless steel and have access panels for easy cleaning and even removal of the conhing elements
• Electric extractor fan provides cross refiner air flow through hopper vent for reduction of volatiles, acidity & moisture
Melangers also come in a variety of sizes, some that fit on a kitchen counter and others that are using for commercial production.
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.

Batch type mixing and grinding machine for thinning ingredients containing minimal 30% fat. Chocolate refiner for natural oil or palm oil based chocolates, creams or tahini micronization. Depending of the adjusted refining process time final product sevimli reach 18 microns fineness.
The largest difference is rather an economical one, kakım very expensive cocoa butter is replaced by relatively inexpensive alternative fats.
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 bey:
Main differences of the chocolate melters from storage tanks are; flat bottom, thicker sheetmetal usage, bottom scrapping and more water capacity inside the jacket. Melters dirilik be used as storage tanks bey well, however storage tanks are only for liquid chocolate storage.
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 yaşama 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. 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 can be downsized for small production scale, then it consists of a conch with vortex chamber, a ball mill and a pump for circulation.
