bleaching, fats and grease - Bleaching, Fats and Grease
bleaching, fats and grease - A common plan is to pro vide two vats, one above the other, the upper one being lined with sheet lead and provided with an open steam coil and stirring gear, the lower one with open steam coil alone. Run the hot fluid fat into the top vat, have some sulphuric acid slightly diluted with water, and add one or two pounds of this to every 100 pounds of fat and stir well. As soon as thoroughly stirred, turn on steam, and continue stirring. Now run the whole into the lower vat, add hot water and turn on steam. When the whole is well steamed let it stand until the water collects at the bottom from which it is drawn off. Hot water is again added and steam applied and the process repeated; this being done about three times to thoroughly wash the fat. After the water is separated and drawn off the last time, the fat is filtered through a bag.
