A heater is provided for supplying hot air to a plenum tube above the drying chamber. The hot air is passed into the drying chamber to enable the product and hot air to be thoroughly mixed together. Cool air is also introduced into the drying chamber at low velocity. The exposure time of the product to the hot air is short and the hot air is introduced to the drying chamber at high velocity.
