Blenders

摘要

A blender has a mixing chamber for reception of materials to be blended. A mixing screw is mounted at a bottom of the mixing chamber for mixing materials within the mixing chamber and delivering mixed materials to an outlet feeding a processing line. A baffle is mounted at the outlet extending about the mixing screw. The baffle inhibits upward movement of material at the outlet tending to cram material into the outlet.

主权项

1. A blender comprising:
a chamber for reception of blend materials, the chamber having a material outlet, a mixing screw mounted adjacent the material outlet of the chamber for circulation and mixing of materials within the chamber prior to discharge through the material outlet, said mixing screw having a pair of opposed blades which are operable to direct material from each end of the mixing screw to a central portion of the mixing screw, said central portion of the mixing screw being located at the material outlet, a drive motor drivably connected to the mixing screw, a baffle, said baffle having at least one opening therein to allow through-passage of material, said baffle mounted in the chamber at the material outlet, adjacent the material outlet but spaced-apart from the material outlet, the central portion of the mixing screw being mounted between the baffle and the material outlet, such that in use the baffle allows a mixing action to occur while, at the same time, the baffle resists upward movement of material at the material outlet to provide a cramming action on the material at the material outlet.
