404. Coco-nuts The Consols of the East 



Ceylon, and the Federated Malay States, so 

 can be said to have proved its claim for 

 recognition as a useful drying plant. 



There are two types of " Chula " dryers for 

 copra, the first type being the continuous 

 " Tunnel " Dryer, which is a self-contained 

 machine and suitable for the drying of either 

 large or small quantities. The second type 

 of arrangement is that of fixed drying racks 

 arranged in a subdivided drying room, the 

 hot air being drawn from the " Chula" patent 

 heater by a fan, and delivered beneath the 

 racks by a system of light galvanized steel 

 piping fitted with valves and outlets. This 

 latter method of drying is suited for large 

 quantities to be dried in bulk. 



The principle of the '' Chula" continuous 

 " Tunnel " Dryer, as its name implies, is that of 

 a tunnel through which the nuts are passed on 

 trucks, moving against a current of hot air from 

 the " Chula " heater. The whole arrangement 

 is extremely simple, and one which can be 

 readily worked and understood by estate 

 coolies, 



The tunnels are supplied either in single 

 units or in groups of two or three, depending- 

 upon the amount of copra to be produced. 

 The sides and top of the tunnels are made of 

 sheet steel and are lagged with non-conducting 

 material. They are shipped in flat sections of 

 suitable size for transport and easy erection. 

 Each end is closed by a swing door also 

 covered with non-conducting material.
