The two secondary fermenters are arranged above the primary fermenters.

This is achieved in that the manure processing device comprises fermenters, a device for supplying air to the fermenters and a device for removing gases from the fermenters.

The primary fermentation apparatus comprises two secondary fermenters and one or more primary fermentors.

b. Fermenters and components as follows

b. Fermenters and components as follows

Material inlets are provided at connections between the secondary fermenters and the primary fermenters.

Agitator apparatus are arranged within the secondary fermenters.

Agitators for fermenters as mentioned in a.above

The anaerobic fermentation tank and the primary fermenters are connected.

Components designed for fermenters specified in 2B352.b.1. as follows

b. Agitators for fermenters as mentioned in a. above

Components designed for fermenters in 2B352.b.1. as follows

Fermenters include bioreactors, chemostats and continuous-flow systems.

A problem associated with large, horizontal fermenters comprising an agitator is that the screw of the agitator caves in despite reinforcing constructions, thereby destroying the fermenter (1).

The software recognizes the connected fermenters at start-up.
