<p>A flow division apparatus comprises a process gas inlet 5 communicating with a process gas outlet by means of a fluid flow path, a separation apparatus comprising two or more separators 3 and 4 arranged downstream of the process gas outlet and a divider apparatus 6 arranged in the fluid flow path. A divider plate 10 is provided downstream from a process gas inlet, for dividing the process gas flow and such that the process gas flow is divided between the two or more gas solids separators 4. The divider apparatus may comprise a rotatable bar 8 and a scraper 12 allowing multiple separators to be used whilst avoiding accumulation of the product on a leading edge of the divider apparatus. The bar may be cooled by circulation of cooling water to a temperature less than the dew point of the process gas. The process gas may comprise gas exhausted from a drying process. The particulate product may be tobacco, herbs or tea.</p> |
