Used once so far. Worked flawlessly on goat milk and was very quiet. A mild surprise: the toggle switch’s “on” position is down, “off” is up. The parts are sturdy enough for home use, but don’t go dropping pieces on the floor or they’ll get dented. The separator disks, especially, won’t tolerate that.Be sure to warm your milk to 100F or so. If the milk fat is not melted, it can’t flow through the separator.Processed just 6l for our first run, and got 400ml cream. That indicates roughly 6.5% which seems high, so I’m guessing the cream is light cream. I’ll know more after I make butter. I have no way to tell how much cream is left in the separated milk, but it tastes surprisingly rich.If you clean the parts immediately the milk products rinse away readily, so don’t delay as it really must be done. Be sure to remove the O ring as milk does get underneath it. Next time I’m just popping the parts in the dishwasher.How much cream is lost during the run? The separator plate assembly trapped 65g of cream inside, even after flushing the system by running skim milk through it. That was about 16% of my cream. You’ll need to process about 100l of milk to keep your loss to less than 1%.The unit came with a spare O ring and float, so I’m guessing these are subject to some wear and tear. I’m not at all sure how easy it will be to get repair parts, should I need them.YouTube videos are useful to familiarize yourself with the parts.Enjoy!
