Container and method for installing an agitator in a container

A container for fermenting bio-degradable substances, the container comprising:

• at least one base and at least one wall, wherein an interior of the container is enclosed by the at least one base and the at least one wall;
• at least one rotatable agitator that protrudes into the interior and is supported in an upper bearing and a lower bearing in an installed position of the at least one rotatable agitator in the container,
• wherein the at least one rotatable agitator includes a shaft that is drivable by a drive,
• wherein at least one stirring paddle Is fixed in position relative to the shaft and configured to co-rotate with the shaft so that substances arranged in the container are stirrable,
• wherein the lower bearing is arranged at the at least one base of the container and a support bearing located at a lower end of the shaft is supported in the lower bearing in the installed position of the at least one rotatable agitator,
• wherein the shaft includes a longitudinal axis that is inclined at an angle between 5 degrees and 60 degrees relative to vertical in the installed position of the at least one rotatable agitator,
• wherein a guide is arranged at an upper side of the container and includes a contact surface for at least a section of the shaft,
• wherein the lower end of the shaft of the at least one rotatable agitator is alignable with the lower bearing into an aligned position of the shaft by moving the shaft along the contact surface so that the at least one rotatable agitator is axially movable from the aligned position into the installed position, and
• wherein the contact surface is oriented parallel to the shaft in the aligned position of the shaft and in the installed position of the shaft and inclined at the angle between 6 degrees and 60 degrees relative to vertical.
