Time in Melangeur and storage

If I do a 1 lb batch of chocolate at home with 10 hours in the melangeur (Santha) and then do everything the same except a 3lb batch. Would the same time in the machine produce consistent results or do I need to adjust for the batch size?

Also, are there any issues in storing cocoa liquor? It takes such a long time to clean the equipment I'm using that it seems like a too process a lot of beans at the same time. For liquor and chocolate in general, are plastic containers ok or would metal be better?

I'm also interested to hear from people with actual experience re. this. I would GUESS it takes longer to do a batch 3x the size because their are 3x as many particles that need to be reduced in size. Once again guessing, but maybe the mass would maintain a higher heat in the machine which could alsoimpact processing time.
