" Hamel- Smith " Rotary Dryer. 

 (Made by Messrs. David Bridge and Co., Manchester). 

 The receiving cylinders, six in number, are filled approximately 

 three-quarters full with the cacao to be dried. These are then placed 

 in position on the revolving framework, which is enclosed in the 

 casing and slowly revolved. The cylinders are fitted with baffle plates, 

 which gently turn over the cacao beans at each revolution so that 

 even drying throughout is the result. The casing is heated to the 

 requisite temperature by means of a special stove, the arrangement 

 of which is such as to allow the air drawn from the outside to 

 circulate around the stove and to pass into the interior of the casing 

 containing the drying cylinders. The fumes from the fuel do not 

 in any way come in contact with the material during drying.
