Charles Ross & Son Co says that its ribbon blenders for multi-phase mixing now come with an optional pressure feed vessel.
While 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, the company said.
Instead of manually pouring liquids through an open blender cover or safety grating, utilizing a pressure feed vessel and spray bar also 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, according to Ross.
The pressure feed vessel, which is designed for compressed air supply up to 20 psig or higher, has an absence of residual product in the piping, and after the blending cycle, it can assist with CIP/washdown, the company said.
The vessels are available in various sizes to accommodate the required volume of the additive liquid phase, and can be mounted and plumbed to ROSS Ribbon Blenders which range from 1/2 to 500 ft3 working capacity.
