The equipment for crushing cocoa beans includes a crushing and screening machine (Fig. 5.28), consisting of a bucket elevator, a housing, a grinding mechanism of percussion, a sieve block cascade

beans dried in a traditional cocoa house replica and greenhouse-type dryer with that of beans dried in a mechanical cabinet oven at 40 C (drying for 8h with a rest period of 16h). Weight measurements were taken at the start of drying and at regular intervals during the drying process, and drying continued until there was no change in bean weight

The cocoa beans dryer machine is making use of the reverse carnot principle, input small quantity of electrical energy to absorb the heat in the air and transfer the heat into the chamber to imporve temperature of chamber, with corresponding dehumidifying

The cocoa beans drying machine adopts continuous mesh belt conveying, rapid heating and precise temperature control. This cacao roaster machine is widely used to dry or roast peanuts, almonds, melon seeds, pine nuts, cashews, etc

He said the commissioning of the solar combination dryer in Bitavavar village was to inspire cocoa farmers to produce quality cocoa. Mr Gaupu said it is easier and cost effective for farmers to have communal solar dryers in order to have consistent production of top cocoa beans to sell to high end markets

Drum dryers air blower cocoa. The impressive 7.0 cu. ft. capacity and heavy-duty motor can handle tough laundry jobs, while Moisture Sensing uses two sensors to closely monitor moisture and air temperatures to help prevent over- and under-drying. Plus, count on a decade of dependability with a 10-year limited parts warranty on the motor and

Cocoa production around the world is characterized by a lack of technical facilities for post-harvest activities, and therefore a good quality of beans is hard to achieve. This situation can be changed by using technological solutions, particularly when they are adapted to specific needs of cocoa producers. Mechanical dryers used in intensive cocoa production exceed the

All rotary dryers have the feed materials passing through a rotating cylinder termed a drum. It is a cylindrical shell usually constructed from steel plates, slightly inclined, typically 0.3-5 m in diameter, 5-90 m in length and rotating at 1-5 rpm. It is operated in some cases with a negative

2007). Cocoa processing consists of two major steps namely fermentation and drying. Fresh cocoa beans are usually fermented using the heap, tray or box methods for 5 to 7 days depending on the condition of the beans (Opeke, 1987). During fermentation, the temperature of the beans will rise from ambient to about 50 to 55 C due

The continuous dryer is used for the drying of cocoa beans, mainly required to dry the shell. This will lead to an increased efficiency in the winnowing section as the shells are more brittle due to the lower moisture level on the outside. This give benefits in the rest of the process, i.e. less wear and higher yield

2.1 Existing cocoa bean dryers There are a few types of dryers that are seen in the industry inclusive of solar dryers, glass roof dryers and intermittent solar dryers. The use of solar dryers is very expensive over other types of dryers, but the solar dryer gives a better quality

The drying of cocoa beans was continued until the cocoa beans are completely dried and attains safe moisture level of about 6 % to 7.5%. 3.1 Calculation of drying rate Drying rate is defined as the ratio of moisture removed per kg of dry weight of material in unit time. The amount of moisture removed on each of experimentation is

Most of the drying takes place while the material falls through the air blast. Using very hot air or combustion gases, rotary dryers can also function as roasters for nuts, sesame seeds, and cocoa beans. A detailed method for the design of rotary dryers, based on a heat exchange approach has been described by Nonhebel (1971)
