Factory/production output

I was playing the latest update 0.6 and tried to install a production line for Pizzas because I like it :smiley: . Ok, that´s not the problem. If I install 1 or more filling machines for tomatoes the output is still 1 can of tomato paste. Why? Is this correct?

After my logic the output in 5 minutes must be like this:

1x filling machine tomatoes = 1 tomato paste can
2x filling machine tomatoes = 2 tomato paste cans
3x filling machine tomatoes = 3 tomato paste cans
4x filling machine tomatoes = 4 tomato paste cans
5x filling machine tomatoes = 5 tomato paste cans

Please correct me if I understood the input/output process wrong.

Thanks
