Everything else / Re: Centrifuges Really Work

Steam exiting the vent of the centrifuge is the exit point for water.

In this scenario, the fuge is not eliminating the water, the added heat, presumably near the boiling point of water is. That is a lot of energy for even a 200L batch and if you are heating it electrically, a fairly slow and expensive process.

On a 20oC day at around 60% Humidity, I can dry and filter a 200L batch of oil in 30 min with well under .5 Kwh of power used with the bubbling/ pumping method.

Small batches through a heated centrifuge is fast and clean.

Spose that depends on what one considers a " Small batch" and what one considers fast.  200L in 30 Min is fast and clean to me and also cheap with the amount of energy I put ( or don't) put into it.

There is no doubting the cleanliness of spun oil but my reluctance to use a fuge has always been the initial cost of the equipment and the inability of a fuge ( on it's own) to dry the oil.  I have  tried them and set them up for friends but the results were never that different of better that what my filtering method was  and certainly did not justify the significant cost.

As said, to dry oil with a fuge requires a separate process which is usually electric the way I have seen fudges set up so is an added energy investment.

I thought the knowledge of water separation was generally understood after all of us "pioneers" tried multiple solutions, sometimes with very messy results.
Like when a hose broke on one of my VO cleaning experiments (pump still running of course) while I was away from the garage for 20 minutes. VO covered the whole floor.
Lesson learned.... no more barbed fitting with hose clamps on the pressure side of a system ! Threaded connection only.
We all have our stories as we earned our right of passage.  ;D
I digress...
With the advent of the high "G" centrifuges and heat applied to the oil on the way into the centrifuge, water is pretty much eliminated and the output from the machine is clean dry oil.
Steam exiting the vent of the centrifuge is the exit point for water. And multiple passes through the centrifuge make it even better.
If you have the space for multiple vessels, settling is super simple and effective too, but takes way to long for me and I don't have the space to keep multiple 200 liter drums or 1000 liter IBC totes in my yard.
Small batches through a heated centrifuge is fast and clean.

Any hydraulic place will sell you copper rings or - perhaps better - "doughty washer" rings.  Just take the banjo bits along and ask.  Cheers

13 - setting TDC, with 2 marks for centering comparator;

14 - setting mark in fly rim, and verifiing with comparator (pencil needing glasses to read scale);

15 - aling the line of the plunger with start injection line;

16 - detail of fine tunning;

9 - start to unscrew the IP tappet bolt;

10 - align the line of the plunger with start injection line;

11 - detail of fine tunning;

12 - final course of the plunger (very important this clearence to not damage de IP);

5 - mark the TDC in the fly rim;

6 - manual spec by Peter Forbes (RIP)

7 - mark -4.25" = 20 BTDC in the fly rim;

8 - reading the comparator value in mm = 4.25" = 20BTDC;
