Wet type High Shear Mixer Granulator for Nutriceutical

1. Work principle of High Shear Mixer Granulator

High Shear Mixer granulator is wet method mixing and Granulating Machine. The powdery material and adhesive in cylinder are mixed completely at the bottom of the machine to achieve humid-soft material, and then cut by a high speed chopper to become similar spherical granules.
Liquid binder is usually fed into the closed container with a Rapid Mixer and a chopper. The result is that the liquid binder and solid will be formed into dense granules.

2. Application of high shear mixer granulator

High shear mixer granulator is widely used in the process of material mixing and granulation in pharmaceutical, food, chemical, pesticide and other industries. The granules are conducive to tablet pressing and capsule filling.

4. Features of high shear mixer granulator

Including dry mixing, wet mixing or wet mixing, cutting, granulating in the same sealed container.
Efficiency will be raised by 4~5 times compared with ordinary granulator.
25% adhesive can be saved compared with other ordinary granulating machine.
The mixing time per batch is about 2 minutes and granulating time is about 1~4 minutes.
The whole operation has strict safe and protective measures.
High speed chopper is used to break down the wet lump to produce granules.
The mixing speed is adjustable, running at a speed of 100~500rpm.
The cutting speed of chopper is adjustable, running at a speed of 1000~3000rpm, which makes the granules more even.
The final granules have medium density to high density with excellent flow and compression characteristics.
The granulation process is very quick and then usually transferred to a fluid bed drying machine for drying.
