Abstract: A fill probe with an in-line mixer accelerates and facilitates automation of a fill and mix procedure required in formulating certain chemical products. In some formulas, the concentrated chemical components that combine to form the resulting formula (e.g., teat dip) have a wide range of viscosities. The in-line positioning of the mixing attachment with the fill probe on the outside of the fill probe creates a dual action mixing operation that mixes the components as they are deliver to a mixing container and continues to mix them after they are combined with other chemicals within the mixing container. By using a combination fill probe and in-line mixer of the claimed design, a user can automate the fill and mix process, decrease the required mix time, and reduce foaming and spillage of chemicals.
