Process and apparatus for aerobic, fermentative hydrolysis, particularly for composting of organic materials.

摘要

A process is used for aerobic, fermentative hydrolysis, particularly for composting organic substances, in a sealed container. Fresh air is introduced to the organic substances. The waste air which is charged with heat and moisture is removed and cooled. The heat of the waste air is transferred to the fresh air which is introduced by means of a heat exchanger (1). To improve the metabolic conditions and, in particular, achieve a higher temperature in the fresh air, the waste air (7) is divided (8) into at least two part-streams (31, 32). The heat of the first stream of waste air (31) is transferred to the fresh air (4) which is introduced (3) by means of a first heat exchanger (1). Using a second heat exchanger (2), the heat of the second stream of waste air (32) is transferred to the fresh air which leaves the first heat exchanger (1), where it has been heated.
