Claim 11:
12. The apparatus of claim 1, wherein the apparatus is configured to create a helical flow of particulate material passing along the drying chamber between said first end and said second end in a first rotational direction; and further wherein the drying chamber includes one or more gas guides or guide passages for directing gas under pressure into the drying chamber from the body of modular construction, for interacting with the flow of gas-entrained particulate material within the drying chamber, wherein said one or more gas guides or guide passages is configured to direct gas in a generally tangential or rotational manner, in a second rotational direction which is counter to said first rotational direction, in order to create a reverse spin effect within the flow of gas-entrained particulate material.
