I would like to ask about equipment selection when scaling up from lab tests
Thread Content
During pilot testing, one of the steps involves separating the layers while they are still hot; crystals tend to form in the lower layer. After leaving that layer to stand overnight, all the crystals have precipitated, and no liquid is visible. Filtration is then easier, and a small amount of liquid can be removed through filtration. May I ask how to operate the operational amplifier at the headquarters? Which container should the lower layer be assigned to?
A filter, washing, and drying all-in-one unit can be used.
I’ve thought about it, but it’s necessary to first crystallize it in a container, and then filter it after the crystallization is complete. Putting it into the three-in-one unit before complete crystallization will result in material loss, right?
Crystallizer, filter, dryer~~~~
What kind of crystallizer? After crystallization, it forms a large piece – how can it be transferred to the filter?
Does that material crystallize into a large chunk?
It depends on your manufacturing process and the properties of the materials. For small-scale production, centrifuges and ovens can be used, while for large-scale continuous production, continuous filtration and drying equipment can be employed.
Yes, after standing overnight there is virtually no liquid left; it is not a very hard solid, but rather a good crystal, from which a small amount of mother liquor can be filtered off
It’s awkward when there’s basically no liquid – the only option then is to handle it as a solid. So far, I’m still not familiar with methods for dealing with solids. . . .
If the crystals are not very hard, the poster could consider using slow stirring to mix the material and then separating it with a centrifuge. This results in a high solid content, which facilitates the subsequent drying process
