Ribbon Vacuum Mixer Dryer

Product Description

RIBBON VACUUM MIXER DRYER

Low Temperature Vacuum Mixing &Drying Process Technik

Application & Process :

The Ribbon Vacuum Mixer Dryer is suitable for mixing and drying the material which can not operate at low Temperature easily oxidized, poisonous in nature. It operates at low Temperature efficiently under vacuum. It is used for raw materials drying and mixing powder or granules of Pharmaceutical Materials, Crystalline, Insecticides, Pesticides, and Food industry and heat sensitive products.The Ribbon Vacuum Mixer Dryer consists of a jacketed cylindrical shell with rotating with specially designed Double Helical Ribbon Agitator type blade by rigid fabricated structure motor, gear box. There is provision for application of vacuum inside the shell and circulation of heating media in the jacket during the rotation of the stirrer. The large heating surface area presented by the internals of the cylindrical shell ensures uniform drying of the product, as the product gently moving while the ribbon stirrer rotates. The diffusive action induced by the mixing stirrer constantly presents a fresh layer to come into contact with the indirectly heated walls of the shell. A well designed sealing system enable maintenance of deep vacuum inside the shell, and also ensures positive circulation of a heating media in the jacket.In operation, material is filled to the top of the outer ribbon. The shaft rotates at relatively low speed and the moving ribbons push the material back and forth mixing it. The outer ribbon rotation displaces the material from the ends to the center while the inner ribbon rotations move the material from the center to the ends. This counter-current action results in homogenous blending. Mixing is achieved in 15 to 20 minutes with 90 to 95 % or better homogeneity. The bottom discharge provided for unloading of the material and easy cleaning of the mixing drum. Specially designed self adjusting sealing arrangement of unique design is provided to ensure that no black particle enters into the mixing drum.
