Defoaming device and method

A defoaming device comprising:

• an elongated container comprising a cylindrical-shaped side wall having a longitudinal direction,
• a liquid flowing platform inside the container, wherein:
• the liquid flowing platform is umbrella shaped thereby substantially fitting into the cylindrical-shaped side wall;
• the liquid flowing platform and the cylindrical-shaped side wall has a gap in between;
• a solution inflow part attached to the container;
• and
• the solution inflow part is configured to allow a liquid solution to enter the container;
• and
• a lifting component attached to the container, wherein:
• the lifting component attaches to the liquid flowing platform inside the container,
• the lifting component is configured to drive the liquid flowing platform to move along the cylindrical-shaped side wall of the container for defoaming the liquid solution when the liquid solution passes through the gap between the liquid flowing platform and the cylindrical-shaped side wall, and
• the lifting component is configured to rotate the liquid flowing platform by 90 degrees, around the longitudinal direction, inside the container while the liquid flowing platform is driven to move along the longitudinal direction of the cylindrical-shaped side wall.
