Extraction is a physical substance separation process, during
which an extract is dissolved out of a hard mixture of substances, the
so-called extraction material with the help of an extracting agent.
process is e.g. Used in order to dissolve the extraction material from
tealeaves. In this example, water and the tea herbs are let into the
U-trough. The interior of the trough is heated by means of a double
jacket. The water dissolves the extraction material from the tea herbs.
By tilting the extractionscrew, the water drains together with the
dissolved extract. A sieve prevents solid particles from being flushed
out. The slowly turning spiral carries the tea herbs to the outlet. The
herbs can be drained with a compression screw, so that no extraction
material is lost.
- continuous extraction
- easy cleaning
