This invention provides a distillation and dehydration apparatus for the preparation of triacetin, comprising a distillation column, a water inlet, an exhaust outlet, a cooking furnace, and a condenser. The distillation column is movably mounted on top of the cooking furnace, and the exhaust outlet is connected to one side of the top of the distillation column. This invention facilitates the containment of thickened oils during distillation, preventing rapid loss and resulting in a smaller amount obtained through distillation. It addresses existing problems where excessively high concentrations of steam are directly condensed during esterification, affecting subsequent condensation rates and causing some triacetin raw material to be lost with the steam, leading to waste. Furthermore, incomplete removal of the extracted esterified raw material after cooking can affect the efficiency of subsequent cooking. Additionally, some raw material drawn into the column may remain in the pipes and on the column sidewalls, and the esterified raw material mist in the steam cannot be utilized, increasing production costs.
