Abstract

La présente invention se rapporte à un dispositif de traitement par fermentation/décomposition qui peut empêcher une substance qui est agitée, de coller et durcir sur les parois latérales d'un réservoir de traitement de décomposition. Sur la surface inférieure (5) d'un réservoir de traitement de décomposition en forme de boîte (2), des sections évidées (20) sont formées près des parois avant et arrière opposées (4) du réservoir de traitement de décomposition. Les sections évidées ont des bases (20b) qui sont plus basses que la surface inférieure du réservoir de traitement de décomposition (2) et lorsqu'une substance qui doit être agitée, est introduite dans le réservoir de traitement de décomposition (2) et agitée par un dispositif d'agitation (7) qui déplace la substance en avant et en arrière entre la paire de parois avant et arrière (4), la substance qui est poussée vers le haut contre les parois avant et arrière (4) par le dispositif d'agitation (7) tombe dans les sections évidées et peut être évacuée à l'extérieur.
