A device for taking powder material into liquid including an inlet to which fluidized powder is supplied with a first pressure, an outlet into a liquid tank having a second pressure less than the first pressure, a powder material intake from the inlet to the outlet, a valve for the powder material intake, and a gaseous medium intake with an outlet into the powder intake with a pressure higher than the second pressure, wherein the outlet of the gaseous medium intake is in the powder material intake downstream from the valve. A method including: applying a vacuum or low pressure to the liquid, passing powder material into the liquid through a powder material intake, providing a valve in the powder material intake, and supplying a pressurized gaseous medium into the powder material intake downstream the valve at least partially during closing and/or opening the valve.

1. A hygienic powder material intake device for taking a food powder material into a liquid, the device having a hygienic design for Cleaning-in-Place cleaning and comprising: an inlet to which fluidized powder is supplied with a first pressure;an outlet directly leading into a liquid tank having a second pressure less than the first pressure at the inlet;a horizontal powder material intake passage from the inlet to the outlet;a first valve including a closing member located inside the powder material intake passage for closing and opening the powder material intake passage;a second valve for closing and opening the powder material intake passage; anda gaseous medium intake device with an outlet for taking a gaseous medium into the powder intake passage with a pressure higher than the second pressure, wherein the outlet of the gaseous medium intake device is located in the powder material intake passage downstream from the first valve,wherein the first and the second valves extend from one end of an inner wall of the powder material intake passage to another end of the inner wall of the powder material intake passage,wherein the pressure after the second valve is always lower than the pressure before the second valve, andwherein the device is configured to transfer the food powder material out of the device when both the first and second valves are simultaneously opened. 2. The powder material intake device according to claim 1, wherein the second valve is located downstream of the outlet of the gaseous medium intake device and/or the outlet of the gaseous medium intake device is located between the first valve and the second valve and/or the second valve is located between the outlet of the gaseous medium intake device and the outlet of the powder material intake device. 3. The powder intake device according to claim 1, wherein the first valve and/or the second valve comprises an on/off valve and/or a seat valve and/or a single seat valve. 4. The powder intake device according to claim 1, wherein powder material intake passage comprises at least two sections being connected by connecting means such that the powder material intake passage is separable and/or dividable and/or openable for maintenance and cleaning. 5. The powder intake device according to claim 1, wherein the gaseous medium intake device comprises a gaseous medium intake valve, and/or a positive displacement feeding device. 6. The device according to claim 1, wherein the closing member is configured to turn around an axis perpendicular to the axial direction of the powder material intake passage for closing and opening the powder material intake passage. 7. The device according to claim 1, wherein the gaseous medium intake device includes a second closing member in the powder material intake passage downstream from the first valve. 8. The device according to claim 1, including valves selected from the first valve, the second valve and the gaseous medium intake device. 9. A hygienic method for taking a food powder material into a liquid, the method being employed on a device hygienically designed for Cleaning-in-Place cleaning, the method comprising the steps of: applying a vacuum or low pressure to the liquid;passing the food powder material directly into the liquid through a horizontal powder material intake passage;providing a first valve including a closing member located inside the powder material intake passage for closing and opening the powder material intake passage;providing a second valve located inside the powder material intake passage for closing and opening the powder material intake passage; andsupplying a pressurized gaseous medium into the powder material intake passage downstream of the first valve and/or between the outlet of the powder material intake passage and the first valve at least partially during closing and/or opening the first valve,wherein the first and the second valves extend from one end of an inner wall of the powder material intake passage to another end of the inner wall of the powder material intake passage,wherein the pressure after the second valve is always lower than the pressure before the second valve, andwherein the food powder material is transferred out of the device when both the first and second valves are simultaneously opened. 10. The method according to claim 9, wherein the second valve is provided downstream the section of the powder material intake passage where the pressurized gaseous medium is supplied into the powder material intake passage. 11. The method according to claim 10, further comprising: closing the second valve,wherein the gaseous medium is supplied into the powder material intake passage downstream the first valve after the first valve has been closed and before the second valve is fully closed, before starting closing the second valve in order to clean the second valve and/or the sealing means of the second valve from powder material,wherein the gaseous medium is supplied until the second valve is completely closed. 12. The method according to claim 10, further comprising opening the second valve before opening the first valve and opening the first valve after the first valve has at least partly opened, wherein the gaseous medium is supplied into the powder material intake passage downstream the first valve at least before starting opening the second valve, at least from before starting opening the second valve until the first valve has been opened almost completely, and at least from before starting opening the first valve until completing opening the first valve. 13. The method according to claim 9, performed with a powder material intake device for taking a powder material into a liquid comprising: an inlet to which fluidized powder is supplied with a first pressure;an outlet directly leading into a liquid tank having a second pressure less than the first pressure at the inlet;the powder material intake passage from the inlet to the outlet;the first valve for closing and opening the powder material intake passage; anda gaseous medium intake device with an outlet for taking a gaseous medium into the powder intake passage with a pressure higher than the second pressure, wherein the outlet of the gaseous medium intake device is located in the powder material intake passage downstream from the first valve. 14. The method according to claim 13, wherein the gaseous medium intake device includes a second closing member in the powder material intake passage downstream from the first valve. 15. The method according to claim 9, further comprising: closing the first valve, wherein the gaseous medium is supplied into the powder material intake passage downstream the first valve at least before the end of closing the first valve, at least after having started closing the first valve and up to closing the first valve and at least from starting closing the first valve until completing closing the first valve. 16. The method according to claim 9, wherein the gaseous medium is supplied into the powder material intake passage downstream the first valve after the first valve has been closed or the first valve is to be opened in order to clean the powder material intake passage from powder material. 17. The method according to claim 9, further comprising: opening the first valve,wherein the gaseous medium is supplied into the powder material intake passage downstream the first valve at least before starting opening the first valve, at least from before starting opening the first valve until the first valve has been opened almost completely, and from before starting opening the first valve until completing opening the first valve. 18. The method according to claim 9, wherein the closing member is configured to turn around an axis perpendicular to the axial direction of the powder material intake passage for closing and opening the powder material intake passage. 19. The method according to claim 9, including valves selected from the first valve, the second valve and a gaseous medium intake device.
