At our Sulphenamide plant we are handling one type of powder product in some hoppers (silos), but we want to change-over several times a year to another similar powder product, but without contamination.

Are there alternatives to provide dry internal cleaning installations in
those hoppers ?

Or maybe some wet internal spraying systems, or etc,..

I am searching for some alternatives for internal cleaning of hoppers.

Could you please provide me some information, alternatives to handle this
problem ?

Awaiting your reply, thanks in advance,
