flashes off, lifting the skin with it The final operation is to pass the product through a skin eliminator Peeling losses can be as low as 15 to 17 percent with ware(ie, table size) potatoes. See TABLE 3.1 Aflash steam peeler (3)Heat-Lye Peeling of lye and heat p America for potatoes. Tubers are first immersed in a very light lye solution and then pass through a gas fired infra red unit at 900oC. After the infra re treatment,most of the softened peel is removed by studded rubber rolls in a mechanical scrubber and final cleaning is effected in a brush washer which uses a minimal amount of water It is claimed that caustic soda usage is cut by 80 percent and water usage by over 90 percent, using this method. There are, relatively, no waste water problems, as the system uses only 15-45 litres per minute against 700- 1800 litres per minute in conventional lye peeling, and the waste peel can be onsolidated to a paste of approximately 15 percent solids which, after neutralising, can be used for animal feedingflashes off, lifting the skin with it.

A flash steam peeler (3) Heat-Lye Peeling The combined use of lye and heat peeling has been developed in America for potatoes. Tubers are first immersed in a very light lye solution, and then pass through a gas fired infra red unit at 900°C. After the infra red treatment, most of the softened peel is removed by studded rubber rolls in a mechanical scrubber, and final cleaning is effected in a brush washer, which uses a minimal amount of water. It is claimed that caustic soda usage is cut by 80 percent and water usage by over 90 percent, using this method. There are, relatively, no waste water problems, as the system uses only 15-45 litres per minute against 700- 1800 litres per minute in conventional lye peeling, and the waste peel can be consolidated to a paste of approximately 15 percent solids which, after neutralising, can be used for animal feeding. 48
