A lot of time has 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 kakım such information is available in textbooks1.
The well-proven design of these Dry Batch Mixers ensures enough mixing time after ingredient dosing for a homogenous dough or paste and yaşama handle up to 3 batcher per hour.
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.
One of the first things a chocolate producer has to consider are the influences of recipe, ingredients and particles on chocolate mass properties bey discussed above. First of all, if raw material cost is less important, e.g. in the premium segment or for making compounds, it is always quite simple to increase the fat content in the recipe in order to achieve the desired mass properties.
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. Birli a minimal shear rate is necessary for the measurement, usually the yield value katışıksız to be extrapolated from the flow curve according to biçim equations, like the ones developed by Casson and Windhab1. Yield values or measurements at low shear stress also have a great practical importance, birli many industrial operations are carried out with masses flowing slowly, for example the equal distribution of still liquid mass in a mould.

This very unique machine resurrects the traditional method of conching and grinding at the same time, bey we know it from the Lindt longitudinal conch1.
Even a large variety of rework birey be processed with the Refiner/Conches following a specific loading procedure. Once a homogenous mass is obtained, the refining and conching process is initiated.
Ball mill grinding process Ball mill grinding is a critical process in the chocolate production industry. It involves crushing
Because of the friction of the steel balls, refiners need external cold water supply. It is possible to use tap or tower water for cooling but we suggest using a chiller for the cooling purpose.
Cleaning of Crates being used for the transport of food products at warehouses decreases contamination. This could also lead to improvements in Product Quality its transportation and storage, number of companies in India are investing on hygienic logistics facilities.
The hygienic process zone is constructed entirely in stainless steel, without edges or open cavities, offering you the highest quality sanitation and making it fast and easy to clean between batches.
To wrap up this blog post, we want to finish with a quick comment about our CocoTerra chocolate maker. We are proud of the CocoTerra chocolate making system that we developed because it provides a complete chocolate-making experience in one compact appliance.
Very often an emulsifier is used to improve flow of hygroscopic particles within the continuous fat phase. During production several incidents occur:
