Extrusion unit consists of extrusion system that has heat and cooling extension as well as drying system operating at specific humidity

摘要

The extrusion unit (1) has an extrusion system (4) that has a drying system (3) for plant-like pieces and a small piece feed (6). The drying system may have a humidity level at one end of dryness between 2-20%, preferably 6-14%. The drying system may be built as a sieve dryer, especially as a strip dryer (34). The extrusion system may have heat extension (12) in the extrusion direction (9) after the cooling extension (13).
