Batch Dried in Several lots

Is it possible to fully dry a batch in several lots without final blending? Would this then be considered as several final batches and should be treated and tested as seperate batches? Any advice?

I think yes, if you are not blending the material after the individual drying then they should be consider them as a different batches and have to be analyzed seperately.
The general procedure is drying individual lots and then blending them and take a sample for final moisture content. As in your we are not doing that then individual batch has to send for moisture and other tests.
