The waste alcohol refining machine is designed to assist restaurants in recovering waste alcohol. Using the principle of distillation, it concentrates waste alcohol into reusable ethanol, serving as a tool for environmental cleaning. By utilizing continuous distillation, waste alcohol is purified into ethanol suitable for sanitation and cleaning. This reduces both waste disposal costs and enhances local environmental hygiene. By utilizing local resources, reduce restaurant waste, foster sustainable dining practices, and promote eco-friendly ethanol production for cleaning.
