We claim:
1. A process for treating cocoa beans comprising passing fresh cocoa beans dynamically through a depulper apparatus for removing and separating a portion of the pulp content of the fresh beans from the fresh beans in an amount of from 10% to 30% by weight based upon the weight of the fresh beans to provide partially depulped beans, drying the partially depulped beans to obtain partially dried depulped beans having a weight which is from 50% to 75% by weight of the weight of the fresh beans and then fermenting the partially dried depulped beans.
2. A process according to claim 1 wherein the partially depulped beans are dried at a temperature of from ambient temperature to 70° C.
3. A process according to claim 1 wherein the partially depulped beans are dried by forcing air at a temperature of from ambient temperature to 70° C. through the depulped beans for from 0.5 hours to 5 hours.
4. A process according to claim 1 wherein the depulper apparatus is comprised of a cylindrical screen and paddles contained within the cylindrical screen for dynamically passing the beans within and through the cylindrical screen and for removing the pulp content from the beans wherein the screen has perforations of a size which allow the removed and separated pulp content to pass through but which prevents the partially depulped beans from passing through.
5. A process according to claim 1 wherein the fresh beans are passed through the depulper apparatus more than once to obtain the partially depulped beans.
6. A process according to claim 5 wherein the fresh beans are passed with water through the depulper apparatus to obtain the partially depulped beans.
7. A process according to claim 1 or 6 wherein the partially dried depulped beans are fermented in a bed having a depth of from 10 cm to 20 cm.
8. A process according to claim 1 or 5 wherein the partially dried depulped beans are fermented first in a bed having a depth of from 13 cm to 30 cm and then fermented in a bed having a bed depth of from 16 cm to 60 cm.
9. A process according to claim 1 wherein from 20% to 30% by weight pulp is removed and separated from the fresh beans.
10. A process for treating cocoa beans comprising first pressing fresh cocoa beans and then passing the pressed beans with water dynamically through a depulper apparatus for removing and separating a portion of the pulp content of the fresh beans from the fresh beans in an amount of from 10% to 30% by weight based upon the weight of the fresh beans to provide partially depulped beans, and then fermenting the partially depulped beans.
11. A process according to claim 10 wherein the partially depulped beans are fermented in a bed having a depth of from 10 cm to 20 cm.
12. A process according to claim 10 wherein from 20% to 30% by weight pulp is removed and separated from the fresh beans.
13. A process for treating cocoa beans comprising pressing fresh cocoa beans with a hydraulic press for from 5 minutes to 60 minutes to effect a weight loss of from 10% to 25% by weight based upon the weight of the fresh beans, drying the pressed beans at a temperature of from ambient to 70° C. to remove further moisture from the pressed beans and then fermenting the pressed, dried beans.
14. A process according to claim 13 wherein the pressed beans are dried to obtain a weight loss of from 30% to 40% by weight based upon the weight of the fresh beans.
15. A process according to claim 13 wherein the pressed beans are dried at a temperature of from 45° C. to 60° C. for from 30 minutes to 150 minutes.
16. A process according to claim 13 or 14 wherein during fermentation, the pressed, dried beans are fermented first in a bed having a depth of from 13 cm to 30 cm and then fermented in a bed having a depth of from 18 cm to 50 cm.
17. A process according to claim 1, 13, or 14 wherein the cocoa beans are Malaysian cocoa bean.
