I have a herd of dairy goats, and a enormous vintage DeLaval cream seperator. But what a beast to use! This little Vevor separator is perfect for household use! I washed all the equipment on arrival, as it comes coated with a light oil film. Then ran a couple gallons of boiling water through to sterilize it. I did not adjust the cream screw, left it halfway out/in. Plugged it in and spun it up. Worked like a charm. A little leakage out of the drain hole, which is normal/expected, thats why it is there! The first run the milk was room temp (24c) and didn't get much cream (8oz for 3 gallon). I've had my milk tested and know my herd average is over 7% butterfat. So I heated the milk to 40c and ran it through again with a final yield of 36oz of cream. I tried messing with the cream screw a bit to see if I could get more, but it wasn't doing much so not worth the effort. Overall with my experience of the cost and difficulty of use of larger commercial counterparts I found this little machine delightful, and it will allow me to incorporate cream and skim recipes into my routine. I do recommend saving up 2-3 gallons of milk to be worth the effort of breaking it out and clean-up afterwards. Be sure to warm the milk as directed to ~100-110f/35-45c for best results ❤️
