How can a machine extrude a round pasta shape with a hole in the middle (e.g penne), without the middle metal part blocking the hole falling away

Question

How can a round shape be made, when the middle part of the metal creating the hole needs to be attached to something, which would create a gap in the shape

Answer 1

Where do you think regular pasta comes from? They hollow out the Penne and out comes a strand of pasta!

Answer 2

I work in a pasta factory.

The large and heavy metal dies have the holes cut out for the pasta to pass through, and those middle parts have support beams, but the truth is, only the part of the hole under those support beams truly forms the shape of the product, and a rotating knife cuts the pasta to the desired length.

So due to the high pressure, the pasta seeps under those support beams and forms the desired shape.

Sometimes when the dies are not cleaned well, the pasta comes out separated, or barely comes out, we usually have this problem with the macaroni die, because it is really easy to get pasta stuck and dry inside those.
