A ribbon mixer is a type of industrial mixing equipment used in the food, chemical, and pharmaceutical industries. It is designed to mix dry and wet ingredients in a variety of applications. It is composed of two counter-rotating helical ribbons mounted on a horizontal shaft. The two ribbons are arranged in such a way that they form a helical pattern within the mixing chamber. The ribbons move material both axially and radially, thus allowing for thorough and efficient mixing. Ribbon mixers are capable of handling a wide range of viscosities and are particularly well-suited for the mixing of dry and wet ingredients. They are often used to mix ingredients that cannot be mixed using traditional mixing methods.
