This company’s ribbon blenders, which are custom-built for multi-phase mixing, now come with an optional pressure-feed vessel. Wherein minor liquid ingredients must be thoroughly blended into powder or other solids, a pressure-feed vessel enables 100% discharge of the liquid component through a spray bar and into the blending zone, ensuring even mixing and consistent batches. In lieu of manually pouring liquids through an open blender cover or safety grating, utilizing a pressure-feed vessel and spray bar facilitates liquid addition while the blender is closed, minimizing dusting and safety issues. The spray bar typically includes four or more spray nozzles so that liquids are uniformly distributed along the entire length of the blender. The pressure-feed vessel eliminates the need for a pump to deliver liquids to the spray bar. Designed for compressed-air supply up to 20 psig or higher, a distinguishing characteristic of the pressure-feed vessel is the absence of residual product in the piping. After the blending cycle, the pressure feed vessel can also assist with clean-in-place or washdown. — Charles Ross & Son Co, Hauppage, N.Y.
