My question is, what is the effective way to move these white flour to plastic bag?
Is it using some kind of pump and pipe to move the wheat flour?
Or is there a better way?
There should be a stainless steel version available for this kind of application.
The bag would probably sit on a scale to get to the proper weight, however, probably just counting the number of revolutions the auger makes would be close enough.
Flour will pack up the auger rather quickly. I would suggest a vibrating, inclined metal tube coming from the storage bin or whatever. Do not ever use compressed air as that will produce a explosive cloud of flour.
