The drying of cocoa beans is an important step in the processing of high-quality cocoa beans because there are still some reactions that can produce good flavor during the drying process. Its aim is to reduce the moisture content of fermented beans 60 to less than 8 so as to ensure good conditions of cocoa conservation. The beans must be spread in very thin layers ideally in the sun to ensure that fermentation stops immediately.

Fermentation allows the bean to develop the flavour compounds and the cherished deep brown colour in chocolates while the acetic acid produced by acetic acid bacteria during oxidation of ethanol is. From cocoa bean to chocolate bar Step 1. Spread the beans on boards.

From exposure to ultraviolet rays From the appearance of mold From the ingress of pests such as mice cockroaches ants etc. Drying After fermentation the moisture content of the beans needs to be reduced from 55 to 75 an appropriate moisture content for secure storage of. Drying of cacao beans is still an essential part of the post-harvest process of the cacao beans.

The drying conditions therefore depend on the fermentation conditions. After fermentation beans are dried to reduce the moisture content from about 60 to 6-8 wb for safe storage and transportation as well as to reduce the astringency and bitterness of the beans. Once farmers have tested beans from all parts of the batch and ensured that theyre properly fermented the beans are poured onto tarps to be dried.

Each cocoa fruit contains white pulp with a maximum of 60 seeds. Natural or solar drying. Forcontinuous drying strategy con- stant drying airtemperature of65C produced better quality dried beans with reasonable drying rate.

DRYING Subsequent to fermentation the water content of the beans about 60 must be reduced to Iess than 75. This method can be done in locations with longer dry seasons such as Cote dIvoire and takes approximately 5 to 10 days. For two stage drying atemperature of60Cin theinitial drying and65Cinthefinal drying stagealsoproduced better quality dried cocoa beans.

After removing the seeds and pulp in the fruit the fermenting process begins.

Artificial drying uses mechanical methods to bring down the cocoa beans moisture content. It was observed that moisture content declined from a maximum of 125 at 5 days to 119 at 6 days of fermentation and remained. Some estates and practically all small farms use sun-drying for 14 weeks but on many estates hot air drying in kilns or rotary driers for.

When the cocoa is quite dry the beans are sorted. Based on experimental results it was found that the time taken for drying of cocoa beans from an initial moisture content of 4935wb to a final moisture content of 636 wb varied considerably right from 04 hours for microwave drying to 30 hours in OYSD.
