The product is for processing infant supplement food. The double-deck steamer and mixer solve the problems of traditional single-cup baby food processors, such as low capacity, uneven stir and odor tainting, allowing faster steaming and finer stirring. The combinations of different steamers provides a series of functions including unfreezing, milk warming and disinfection. Other features such as a large LED display, status indicators and touch-screen dashboard offer a better operating experience.
