I don't own an oil burner, but was thinking about this filtering.............
17 years in the restaurant biz, I have filtered a gallon or two of shortening. We had different ways of filtering it. One method you just poured it thru a cone filter into another(spare) vat. The other method(safer) you had a filter machine. It also had the same type filtering paper. Basically a one time use stuff, but would do all the vats. We also had a powder that we poured onto the filter, was called filter media, which aided in the filtering to remove even more/finer particles, which is what breaks down the quality of your shortening.
Sooo, I am wondering if a person was able to get ahold of such a machine and filters, and the media, if it would be beneficial for this type application?
Just a thought for you greasers!
