Control kettles to boil soap ingredients.
What does a Boiler do?
Controls kettles to boil soap ingredients, such as lye, resin, palm oil, and tallow, to specified consistency: Opens valves to fill kettle with ingredients in specified amounts, and weighs and dumps ingredients in kettle, using scale. Opens steam valve to heat kettle to specified temperature. Observes boiling rate, reads temperature gauges, and turns valves to maintain temperature within critical limits. Boils ingredient for specified time and draws and tests sample for consistency, specific gravity, and chemical content, using laboratory equipment, such as hydrometer. Starts pumps and opens valves to transfer mixture to storage tanks. May stir ingredients with paddle.
