? about old De Laval cream separator

greenspun.com : LUSENET : Countryside : One Thread

Does any one have experience with older Delaval Junior cream separators? I am looking at 2 differnt ones to purchase. One of them has several cone shaped discs that fit into the separator. The other has none. My question is....Are these discs a necessary item for cream separation? And, were some De Laval separators made that did not require the use of these discs? Thanks in advance for your help, Chris

Check out the Older Messages catagory for Kitchen Equipment. There should be several threads there on separators, including one from John Hill in NZ who discusses them in detail. Just do a Control and F key at the same time, then search on either cream or separator.

The disc's that you are describing are absolutely essential for the correct seperation of milk and cream. I've been repairing all types of centrifuges for years. The type you're contemplating buying is called a high speed disc type centrifuge. The cream seperators use a food grade stainless steel, while the oil seperators use regular steel. Getting back to the disc's. They provide a larger surface area for the seperation of the cream and milk. Both the cream and milk have different specific gravities and increasing the centrifugal force on the liquids causes them to seperate. If you have further questions, you can e-mail me direct or contact DeLaval, now called Alfa-Laval. They're located in Ft. Lee, NJ. Make sure that spare parts are available for the model you finally purchase. An always service these centrifuges by the book. It's not a pretty sight what a centrifuge can do when not assembled correctly. Remember these machines can rotate a up to 7 or 8,000 RPM's.That's a lot of G-forces.

Good Luck ! aka.......www.TheChandlerCo.net

Thanks Ed, for the explanation regarding the increased surface area. I am just back from a 1600 kilometre drive through the South Island of NZ and saw about six old cream spearators doings duty holding up roadside rural mail boxes. Also saw a perfect Lister separtor complete with all tools and instruction manual in an antique shop and another shop has a white 'streamlined' Alfa Laval that also seemed to be complete, about US$210 each.
