  • the possible throughput of rotting material in the unit of time can be easily adapted to the needs of the operation in relation to smaller quantities and without a drop in efficiency by changing the throughput speed accordingly, which is due to the frequency of the rotation of the mixing angle in connection with the lifting the scraper is easy to carry out.

In the lower area of the support and base plate 15, this is located above a collecting basin 21, provided with holes 20 so that parts of the rotting material 14 which have been entered into the space 4 and which are not absorbed when the organic components flow through, reach the collecting basin 21 and be brought back to room 4 from here either to the slurry tank or from above.

Abstract

Afin de décomposer rapidement par putréfaction des déchets organiques, tels qu'excréments d'animaux, déchets végétaux et similaires, on introduit ceux-ci dans des puits inclinés et fermés, on les ameublit et on leur applique de l'air de traitement en circulation constamment enrichi par l'adjonction d'oxygène. Afin d'assurer une décomposition uniforme avec des agencements aussi simples que possible, la matière à décomposer (1) est introduite dans la chambre (2), puis est soulevée selon les besoins par des râcleurs (4) et transportée par les supports inclinés de mixage (3) jusqu'aux puits (5, 6, 7) et finalement est retirée de l'installation, derrière le dernier puits (7), par des agencements appropriés, par exemple une vis sans fin transporteuse (8).
