oil refining process

In Oil and Fats Production (especially Palm Oil), Cristallization and Filter Press process has importent role. If we want have clear oil so we must make perfect Cystall. Formed Crystall transfered by screw pump to filter press.
why must use screw pump?
because with screw pump, crystall that has been formed still intact. not crashed by pump rotation.
so importance this screw pump then we should be more observant in selecting and determining specification pump used.

www.diamondfasteners.com/mil-spec-hardware.htm provide us information about any kinds of screw from welding screw until mechine screw. back to our topic that refining oil depend crystallization and filter process, and we have known that filter press can separate perfectly if crystall that formed big one. then oil can be sparated wit fat (crystall). if large crystall that has been formed, press process can be done easily and the amount of fat that passes membrane into oil just a little.

But if we use gear pump or hydrolic pump it can caused crystall crash in small pieces and when pressed to filter, fat can passes membrane easily. so oil that produced looks cloudy.

oh yahh! ..... screw pump that I mean here us scroll pump, that using screw to prompt mixture oil and fat to filter press.
