Learning Process no. 1.2: Extracting lanolin from sheep wool
I'm trying to different processes for extracting lanolin
Cold prewash: I've washed it 4 times while it has soaked for a few hours about 5.
"The wool grease is continuously removed during this washing process by centrifugal separators, which concentrate it into a wax-like substance melting at approximately 38°C" - Sengupta, Amit; Behera (2014). "Comprehensive view on chemistry, manufacturing & applications of lanolin extracted from wool pretreatment,also used in vitamins" (PDF). American Journal of Engineering Research (AJER).
That means the cold wash may still have the lanolin oil
I possibly have to investigate how to do some centrifugal separation?
Boiled: I would prefer not to use this method as i understand from my research that the wool will not be useable after having it boiled. "Wool felt melts between 105 and 110F" - p. 50. the Big Book of Handspinning by Alden Amos
The water needs to boil for a few hours.
I'm reading from different sources especially this thread on permies.com

And watched different videos on YouTube:
