Shape | after each batch. Crystals will remain in the crystallizing vessel and transfer lines and potentially become active as seeds. Crystals in the wet part of the reactor typically are dissolved during the transfer of the still undersaturated solution into the crystallizer and act as “autoseeds”. The transfer of the suspension from the crystallizer to the separation unit can have | |
