The temperature rise in the fermentation process takes place periodically. In the first 12 hours, the temperature reached 25˚-27˚C. At that time there is a process of fermentation by yeasts pulp, converted into ethanol and organic acids. The second day, the temperature reached 32˚-36˚C. Ethanol and dead yeast converted into acid by bacteria. This process continues until the third day and thereafter in a temperature of 42˚-48˚C. On the third day and thereafter, the success factor of the fermentation process is air circulation well. Cocoa beans were converted into
