A process and apparatus for yielding one or several plant ingredient(s) from plants by steam/water vapour distillation, said apparatus comprising a steam generation unit (2), a distillation still (6), a head (9) of the distillation still (6) provided with a thermometer (10), a condenser (11) and a receiving vessel (12) for collecting the plant ingredient(s) obtained; wherein
- said distillation still (6) has a ratio of diameter (D) to height (H) in the range of from 1 : 25 to 1 : 2;
- said head (9) of the distillation still (6) is connected to the condenser (11) via an ascending pipe (20) and a bridge (21), wherein the head (9) of the distillation still (6), the ascending pipe and the bridge (21) are provided on their inner walls facing the uprising steam with a surface having recesses, whereby the flow of steam is guided through the head (9) of the distillation still (6), the ascending pipe (20) and the bridge (21) on micro-turbulences; and
- the condenser (11) is a balloon condenser (11) having arranged at least three balloons in a descending direction. |
