- a further advantageous embodiment of the invention provides that the axle shaft is detachably coupled to the output shaft of one motor at each of its ends which are passed through the bearings in a liquid-tight manner.
- the motors can be flanged to the adjacent bearing block with their motor housing.
- the motors expediently have a torque support which projects essentially radially beyond the motor housing and can be positively anchored to the relevant side wall.
- a detachable mountable on the upper edge of the lower container part is upwards and open container attachment provided below.
- the container height can be increased and at the same time it can be achieved that the container attachment can be removed from the lower part of the container, either with or without an agitator assembly, for cleaning and maintenance purposes, for example.
- the bottom part of the container and the top part of the container can advantageously be connected to one another at flange portions projecting in the edge region of the front and rear walls.
- the flange section projecting on the rear wall of the lower container part expediently has at least two open edges and the flange section projecting beyond the end wall has at least two closed openings for the passage of one flange screw penetrating the flange section of the container attachment.
- at least the flange screws on the end wall are flanged to the container attachment.
- the container attachment can be detachably connected to one of the bearing blocks in each case via flange portions projecting outwards in the region of its lower edge on the side wall side.
