The diagram illustrates the process of chocolate production, beginning with the cultivation of cacao trees and ending with the molding of the final product. Overall, the procedure consists of nine main stages, starting from the natural growth of cacao pods and involving several mechanical and chemical steps before chocolate is ready for consumption.
Initially, ripe red pods from cacao trees are harvested, and the white cocoa beans contained inside them are extracted. These beans are then subjected to a fermentation process lasting between two and ten days. Once fermentation is complete, the beans are spread out under the sun to dry. Following this stage, they are roasted at a temperature of 120 to 150 degrees Celsius, which helps to enhance their flavor.
Subsequently, the outer shells of the roasted beans are removed, leaving the inner parts to be crushed. This results in the production of cocoa liquor, which is then refined further through a process called conching. After this, the chocolate mixture is tempered, a step that stabilizes the texture and improves its quality. Finally, the product is poured into molds to form solid chocolate.
In summary, chocolate manufacturing is a complex process that involves both natural treatments, such as fermentation and sun-drying, as well as industrial techniques like roasting, crushing, and conching, all of which are essential to transform raw cacao beans into the final product.
