After the successful tests, New England Coffee installed a model 700-TH-25-SS rotary batch blender. The stainless steel blender's drum has a 25-cubic-foot batch volume and a 500-pound capacity. The unit has an internal sprayline to apply liquid flavoring to the coffee beans. The sprayline and nozzles are mounted off-center in the drum. The mixing action continuously replaces the coffee beans in the spray zone so that a thorough coating occurs with no overspraying. The rotary batch blender's internal lifters and baffles, which provide the blending action, are bolted to brackets that are welded to the drum wall. For more stringent sanitary applications (such as food and pharmaceutical production), the lifters and baffles can be continuously welded to the drum wall.
