Crystallization process

Excuse me, does anyone know when the seed crystals should be added? What is the amount to add? I use cooling crystallization
It is chosen to add it before the temperature point at which crystallization begins during cooling; this requires pilot testing； For a crystallization tank with a capacity of 2 cubic meters, for example, about 1 KG is sufficient.
I have a tank with a capacity of 3.6 cubic units – is that not enough?
Are there any requirements for selecting those seed crystals? I want to make crystals within 1mm? Is it okay to use a seed crystal within 1 mm?
The seed crystal should be added before nucleation, with the amount determined by the process requirements.
I added it during crystal formation, but why are the particles still large and uneven?
In addition to being related to the amount of seed crystals and the timing or concentration levels, it is also connected to the control of the crystallization process, and at times it is crucial
Could you give me some information on seed crystallization? This is my email address: zhoulukun87@163.com. I also want to ask whether the seedlings I planted have grown
Check out my blog; I’ve summarized my strategies for adding seeds.
The book on industrial crystallography explains it clearly: it’s simple to calculate based on the total amount of solute in the reactor, the desired yield, and the volume ratio of product to seed. It’s harder to determine the addition time, as it varies from one material to another.
It’s been such a long time since that post; I don’t even know why I should reply
