A method for manufacturing a detergent portion unit including a dimensionally stable gel. A mixture of a detergent and a gelling agent is provided and fed to a shaping device, such that the mixture is at least partially solidified in the shaping device and a solid gel strand is discharged. The strand is transported using a transport device and the solid gel strand is cut to length using an ultrasonic blade to form the solid gel unit.

A method for manufacturing a detergent portion unit including a dimensionally stable solid gel is described. First and second flowable compositions are mixed using a mixing device to form a surfactant-containing and gelling agent-containing mixture. The surfactant-containing and gelling agent-containing mixture is passed through a shaping device until the surfactant-containing and gelling agent-containing mixture solidifies to form a dimensionally stable solid gel strand. The dimensionally stable solid gel strand is continuously discharged from the shaping device.

A method for manufacturing a detergent portion unit including a dimensionally stable solid gel is described. The method includes passing a detergent-containing and gelling agent-containing mixture through a shaping device such that the detergent-containing and gelling agent-containing mixture is at least partially solidified in the shaping device and a solid gel strand is formed. The solid gel strand is discharged and transported using a transport device including at least one movable conveying element and at least two side elements that can be moved synchronously with the movable conveying element. The conveying element and the side elements form a conveying path laterally delimited by the side elements. The side elements have embossing elements which project into the conveying path and create an embossment into the surface of the solid gel strand.

This invention relates to novel detergent compositions comprising bacterial mannanase enzymes. The detergent compositions comprising bacterial mannanases are useful in laundry and cleaning applications wherein degradation or modification of mannan is desired. The invention also relates to the use of said detergent compositions in laundry and cleaning applications as well as a method for degrading mannan.
