Alkalising and drying of cocoa nibs with process reactors from BOLZ
As a luxury food, chocolate is indispensable for many people. However, it is a long way from an untreated, sour-tasting cocoa nib to delicious chocolate. A central step in this process is the alkalisation of cocoa nibs and the associated refinement of the precious raw material.
With its central shaft cooker/alkaliser of the CCM series, BOLZ offers a powerful and versatile process reactor for the alkalization and drying of cocoa nibs. This process includes operation under vacuum, use as an overpressure reactor, homogeneous mixing and sterilisation of the broken cocoa nibs.
With its sanitary contained design and its flexibility, the BOLZ central shaft cooker/alkaliser CCM meets the highest standards regarding product quality in combination with short reaction times and gentle product handling. This means that all process steps, such as heat treatment by adding steam directly into the reactor vessel, treating the cocoa nibs at overpressure and subsequent drying at negative pressure, can be carried out in one machine.
Production process of alkalised cocoa
Alkalised cocoa is an ingredient used for example in chocolates, cakes, confectionery and beverages providing unique taste experiences. As the untreated cocoa beans are initially very sour after fermentation and do not have a good taste, they are broken into cocoa nibs and heated by the addition of steam. By means of overpressure and temperature, an alkaline solution is added, reducing the bitter flavouring components of the untreated cacao nibs and raising the pH value to approx. 7. Afterwards, the unwanted bitter substances have to be washed out and the colour of the cocoa has to be adjusted. A further process step includes the gentle and time-saving drying of the product in the same machine.
