The spiral mixing blade of the conical mixer initiates a three-dimensional flow of the mixing goods; creating a helical upward movement on the periphery and downward flow in the centre. This conical mixer guarantees very good mixing results and complete discharge. It can be used as powder blender for dry powder, wet suspensions as well as liquids, paste and dough. The vertical mixer can be designed to conform with FDA and 3-A Sanitary Standards to be used as a sterile mixer and reactor which also meets EHEDG requirements.
