GEA BATCH FORMULA® MIN High Shear Mixer

Tackling challenges

The GEA BATCH FORMULA® MIN High Shear Mixer gives great functionality, without complexity, to address what customers say are key challenges when mixing emulsions and dissolving powders. The high shear mixing technology minimizes the risk of retaining undissolved powder agglomerates or creating unstable emulsions that could then result in phase separation in downstream equipment. And reducing that risk can then help to improve final product quality and yield.

Attention to detail

The GEA high shear mixing device (HSMD) has been developed using the latest computational fluid dynamics tools to help optimize flow patterns and – by off centering the HSMD in the tank - avoid creating vortices. This ability to optimize flow characteristics means the system applies shear forces efficiently to fluidize powder and hydrocolloids into liquids. The off centered HSMD also makes it possible to position the outlet at the lowest point, allowing for complete drainage of product, and also complete emptying of the system after CIP.

Key benefits

• Low CAPEX and OPEX   
• Ergonomic design with easy operator access for maintenance and adjustment   
• Integrated tank cleaning means fewer manual tasks, and potentially less use of water and chemicals 
• Small unit footprint makes installation possible where space is limited 
• Single system that can be used for a wide range of powder dissolving mixing applications 

Built for great results

The skid-mounted GEA BATCH FORMULA® MIN High Shear Mixer has been built for flexibility. The 300L tank has a top opening lid so powders or other ingredients can be manually added. Two inlets with manual valves for pumping in liquid ingredients are located near the direct drive-operated HSMD, which is connected at the base of the unit. All parts in contact with the product are made from stainless steel EN 1.4404 (AISI 316L). Other parts are made from stainless steel EN 1.4307 (AISI 304L). 

Users can select different types of stator dependent on the application, and easy access makes switching the stator relatively simple. The HSMD is controlled via a variable frequency drive (VFD) that allows fine control of turbulence inside the tank. Temperature in the tank can also be viewed on the VFD. It’s been shown that compared with conventional mixer tanks designed with a top-mounted high shear agitator, the GEA BATCH FORMULA® MIN High Shear Mixer can significantly reduce process times.
