| 摘要 |
Apparatus for continuous fermentation of tea under temperature controlled conditions, comprises at least one conveyor (1,2,3) having a perforate support (20) for supporting a layer of macerated tea leaves, and cooling means (6-12) for passing a stream of oxygen-containing cooling gas through the perforate support and the layer of tea so as to control the temperature of the layer. The perforate support may be a fabric or perforate metal conveyor belt. The cooling gas is preferably refrigerated air, optionally enriched with pure oxygen. <IMAGE> |
