Morphology
The meaning 'to remove or separate by passing through a sieve' is directly and predictably derived from combining 'sieve' (to pass through a mesh to remove lumps) with the particle 'out' (indicating removal/separation). This verb+particle composition is a common, cross-linguistically transparent pattern, so a B1 learner familiar with both constituents should be able to infer the MWE meaning.
Etymology
Sieve out comes from the simple image of using a sieve: you shake a mix so the small bits fall out through the holes while the larger or unwanted pieces stay behind. So, to sieve out something means 'to separate' or 'remove' the unwanted parts from a group or mixture.
