An advantage of the invention is that the mixing unit can be carried by one person, which simplifies the handling of the mixing unit. A further advantage is that dosing and mixing of a cement product takes place automatically. The mixing of the cement product thus may take place continually. ## Claims ### Claim 1 A mixing unit for mixing of a cement product, wherein the mixing unit is carryable, comprising: a mixer for the mixing of powder and water, and an outlet pump for feeding out the finished mixed cement product, wherein the mixing unit comprises a receiver part for powder, dosing equipment for powder and dosing equipment for water. ### Claim 2 (depends on 1) The mixing unit according to claim 1, wherein the mixing unit weighs less than 32 kg. ### Claim 3 (depends on 2) The mixing unit according to claim 2, wherein the mixing unit weighs less than 25 kg. ### Claim 4 (depends on 3) The mixing unit according to claim 3, wherein the mixing unit weighs less than 20 kg. ### Claim 5 (depends on 1) The mixing unit according to claim 1, in that wherein the mixing unit further comprises an electronic control unit that controls the mixing of the cement product. ### Claim 6 (depends on 1) The mixing unit according to claim 1, wherein the mixer comprises an open mixer screw with a spiral screw without a central shaft. ### Claim 7 (depends on 6) The mixing unit according to claim 6, wherein the mixer housing is made of a flexible material. ### Claim 8 (depends on 1) The mixing unit according to claim 1, wherein the mixer and the outlet pump are arranged along the same central axis. ### Claim 9 (depends on 8) The mixing unit according to claim 8, wherein the mixer is operated by a first motor and the outlet pump is operated by a second motor. ### Claim 10 (depends on 1) The mixing unit according to claim 1, wherein the mixing unit further comprises a flexible tube cleanser which moves along a flexible outlet tube connected to the smoothing compound outlet of the mixing unit, and the flexible tube cleanser comprises two pressure rollers to press the flexible tube together. ### Claim 11 (depends on 10) The mixing unit according to claim 10, wherein the flexible tube cleanser driven along the flexible tube by way of a pressure applied from the smoothing compound outlet. ### Claim 12 (depends on 1) A mixing device (1) for handling of a cement product, comprising the mixing unit according to claim 1, wherein the mixing device further comprises a feeder unit to feed in powder to the mixing unit and a flexible tube bundle connecting the mixing unit to the feeder unit. ### Claim 13 (depends on 12) The mixing device according to claim 12, wherein the feeder unit comprises a powder transporter and at least one powder tank. ### Claim 14 (depends on 12) A method for mixing a cement product with a mixing device according to claim 12, comprising the steps of feeding powder from a powder tank in a feeder unit to a receiver unit through a flexible tube, dosing powder from the receiver unit with dosing equipment to a mixer, simultaneously dosing water to the mixer with dosing equipment, mixing the powder and the water with a mixer, feeding the finished mixed cement product out with an outlet device. ### Claim 15 (depends on 14) Method according to claim 14, wherein the method comprises the step of automatic cleaning of the mixer at a predetermined time.
