Abstract: An immobile container for the cheese curd is in the form of a body of revolution having a substantially horizontal axis; and a tool which is rotated by a drive shaft about the container axis is arranged to cut and stir curd situated above as well as below the container axis. The tool preferably has several side-by-side sections extending from the drive shaft to the surrounding wall of the container and forming an angle with each other, each section having spaced cutting members and also having swingable flaps movable to and from positions in which they cover at least parts of the interspaces between the spaced cutting members.
