bc.gold 3,403 #1 Posted September 26, 2021 (edited) This is waste restaurant fryer oil being made into soap using the hot process which allows me to separate the glycerine from the actual soap. Apparently the more valuable glycerine maybe further refined by heating then passing it through a centrifuge. Once the glycerine is removed the soap takes on a much better color, the glycerine can be made into soap but has many other uses as well. The most difficult part of this project was finding a metal drum, the large stainless bowel was brought back from my B.C. trip, the old Coleman camp stove was a landfill score which is running on automotive gasoline - unleaded ethanol blend. This batch of soap is being made with sodium hydroxide aka lye, which make a harder bar, next batch I'll try potassium hydroxide recovered from wood ash for a softer bar or perhaps a liquid soap. Wood ash is covered with water, distilled water works best, let it soak overnight then evaporate the filtrate down, when an egg will float you know your concentration is right to proceed to your next step - make soap. Soap can be made using the cold or hot process, cold soap takes longer to cure two to three weeks while soap from the hot process is ready to use within a couple of days of curing..For my soap molds I'm cutting the plastic oil containers lengthwise giving me two halves.

bc.gold 3,403 #2 Posted September 26, 2021 (edited) After cooling overnight then this morning I skimmed off the junk then decanted most of the glycerine what was left was milled into the soap which at this point looks like cheese curds after cold milling it now looks like Butterscotch pudding. The pudding was transferred into molds to cure. The crude glycerine to clarify gets heated then passed through a centrifuge producing 3,000g's of mechanically produced gravity, as the centrifuge project unfolds I'll post into this thread.

bc.gold 3,403 #3 Posted September 27, 2021 There's a process called salting, the purpose is to remove rancidity, glycerine along with excess lye. This is the same batch of soap from above after salting, I used pickling salt with about five gallons of water, the color has improved. Share this post Link to post Share on other sites
bc.gold 3,403 #4 Posted September 27, 2021 Some bits n pieces I've been saving for a centrifuge build, the pipe is abrasion resistant ( A R ) from a grain augur, the spindle from a large mower deck, the propane tank becomes the outer shell. Just need to have some rings laser cut then the welding begins. 1 Share this post Link to post Share on other sites
Jeff-C175 7,202 #5 Posted September 27, 2021 OMG! I mis-read the title! I thought it said "Making Homemade SOUP" ! And when I looked at the pics before reading anything further I thought... " GOOD GAWD! WHAT IS HE EATING!!!!!" ha ha ha ha ha The final product does look like Chocolate Mousse though, doesn't it? I've got a good recipe for Homemade Soup though... all it takes is WATER, and ONE NAIL. 1 Share this post Link to post Share on other sites

bc.gold 3,403 #9 Posted October 10, 2021 (edited) In one word, what makes home made soap so great - glycerine. Glycerine is a valuable by product which is stripped out of commercially made soaps. Edited October 10, 2021 by bc.gold Share this post Link to post Share on other sites
Jeff-C175 7,202 #10 Posted October 10, 2021 Do you need to protect that soap from vermin? I've found bars of soap stored out in the shop eaten by them! Maybe they were constipated? Share this post Link to post Share on other sites

bc.gold 3,403 #12 Posted October 14, 2021 (edited) Our resident bear even refused this grease, and I would never eat anything from the restaurant it came from. Read somewhere rancid fats and grease are melted over a layer of brine the junk falls to the bottom and you end up with usable oils. That remains to be seen, so much foreign stuff in this grease I'm going to process it twice. Edited October 15, 2021 by bc.gold Share this post Link to post Share on other sites

EB-80/8inPA 1,655 #14 Posted October 14, 2021 Well, at least that grease didn’t come from the liposuction clinic… That would really be gross. 1 Share this post Link to post Share on other sites
bc.gold 3,403 #15 Posted October 17, 2021 (edited) Melting that horrible looking restaurant grease three times over hot water gave me some nice looking fats, it's now almost pure white without any smell, I woke at 5:00 am this morning with the thought of making suet logs for the birds. From the looks of this product below it looks like I may have recovered several hundred dollars worth of tallow for the birds.

Tank has been cut in half with a round hole in the bottom to accept the spindle, visited the machine shop today giving instructions for plasma cuts which should be ready towards the later part of the upcoming week. On the way home stopped in at the seed cleaning plant, I now have four five gallon pails of wheat to turn into ethanol used to make glycerine soap.

bc.gold 3,403 #18 Posted November 3, 2021 (edited) Parts were a day early. In the fist image a pair of large rings, the one with the same OD of the tank gets welded at the top, other ring gets welded to an inverted tank top which becomes a funnel. Center pipe shown in funnel is cut to reach within 1.5" from the bottom of the centrifuge bowel. Of the smaller rings the widest is welded 1.5" above the base plate which becomes the bottom of the bowel the next two rings are welded in at the same distance. Still have to notch the bottom rings on their OD, when placed for welding those notches will be 180 degrees apart, purpose of the slots these will make cleaning easier. When used to recover precious metals. Edited November 4, 2021 by bc.gold Share this post Link to post Share on other sites

From my personal experience soap from potassium hydroxide using the cold process, it takes about 30 days for the soap to completely cure. You won't be dissapoined as you'll soon learn homemade soap cleans grease and paint from hands much better than commercially made soaps. Share this post Link to post Share on other sites

bc.gold 3,403 #22 Posted November 27, 2021 (edited) 1 hour ago, Handy Don said: Why is that? Because it contains glycerin whereas in the majority of commercially manufactured soaps it has been removed to make more valuable products. Uses. Glycerine is used as a sweetener and a preservative in various baking items. It is a powerful cleaning agent for laundry and dish detergent, cleaning oil-based paint from paintbrushes and a grease cutter on various items. Glycerine is used in makeup remover, soaps, lotions and hair products. Edited November 27, 2021 by bc.gold 1 Share this post Link to post Share on other sites
