 WVO Tests
Customer sent some WVO samples to be ran in our lab centrifuge. They are currently running the samples through a two stage filtration process and wanted to see what centrifuging could do with their WVO.
This is a picture of the two samples. The samples were shaken to mix everything up that had settled during shipping. This is sample 1 after 5 minutes in the centrifuge. Control on the left. Centrifuged on the right. The samples were shaken to mix everything up that had settled during shipping. This is sample 2 after 5 minutes in the centrifuge. Control on the left. Centrifuged on the right.

These are the two samples side by side after 5 minutes in the centrifuge. Control samples are to the left of the centrifuged samples. Sample group 1 is left of sample group 2. Sample group 1. Control, 5 minute, 30 minute side by side. Sample group 2. Control, 5 minute, 30 minute side by side.

Sample one heated to 180F for 1 hour and centrifuged for 5 minutes. Sample one heated to 180F for 1 hour and centrifuged for 30 minutes. Sample one heated to 180F for 2 hours and centrifuged for 5 minutes.
Sample one heated to 180F for 1 hour and centrifuged for 5 minutes. Sample one heated to 180F for 1 hour and centrifuged for 30 minutes. Sample one heated to 180F for 2 hours and centrifuged for 5 minutes.
Sample one heated to 180F for 4 hours. You can see the water vapor condensing at the top of the vial. This oil was wet, not with free water but more likely the oil was emulsified. Sample one heated to 180F for four hours and centrifuged for 5 minutes. You can see it's becoming more clear. Sample one heated to 180F for four hours and centrifuged for 30 minutes. You can now read the numbers on the vial.

Sample one heated to 180F for five hours and centrifuged for 5 minutes. Looks pretty clear. Sample on the left was heated for 5 hours and centrifuged for 30 minutes. Sample on the right was heated for 7 hours and centrifuged for 5 minutes. It is becoming evident that careful heating plays an important part.
