Brings back memories of times I did not like! When I was in college, I had to work at the "abattoir", (fancy name for slaughter house on campus). We had a fancy machine that had paddles on it, with hot water. We put the pig in, and it came out mostly clean of all hair! I would have to clean by hand what it did not get.... yuck. I will never forget the smell. Then cleaning the machine after we were done for the day.... double yuck!
I prefer my pork lean, so we process our pigs at about 260 pounds now.
The pictures are cool, thanks for sharing.
