1. A tank comprising:
a first dome-shaped surface being formed of steel and having a perimeter defining a first diameter;
a second dome-shaped surface opposite the first dome-shaped surface, the second dome-shaped surface being formed of steel and having a perimeter defining a second diameter larger than the first diameter of the first dome-shaped surface; and
a cone-shaped wall formed of the steel and having a top perimeter opposite a bottom perimeter,
wherein:
the top perimeter of the wall is attached to the perimeter of the first dome-shaped surface and defines a top interface void of angled corners on an inside surface of the tank,
the bottom perimeter of the wall is attached to the perimeter of the second dome-shaped surface and defines a bottom interface void of angled corners on the inside surface of tank, and
the wall attached to the first dome-shaped surface and the second dome-shaped surface defines an oval-shape void of angled corners on the inside surface of tank such that, when a product contained in the tank is displaced, the product is displaced in a torus shaped vortex between the first dome-shaped surface and the second dome-shaped surface.
