I've got a 55l polyprop (PP) processor - bad choice. Nothing sticks to it -
silicon peels off, epoxy flakes away. Works best to have mechanical seals to
stop leaking. There is specialized equipment for bonding PP to PP - I was
quoted 4500ZAR (715USD). If you're mass manufacturing processors and
Been there done that. Stainless best, then plain old steel. Will
probably use a 55 gal drum or a Appleseed-based when I scale up my
current stainless rig.
Plastic ok to learn on.
