Vertical ribbon mixers and blenders

Our vertical ribbon mixers and blenders are particularly targeted at the food industry and pharmaceutical industry, as they ensure good mixing and the absence of residues during emptying. They can also be used as homogenizers for powders of equal type but different lots.

Vertical ribbon mixers design

Gimat vertical mixers are characterized by a conical body with a special vertical axis ribbon screw.

Rotation of the helicoid blade creates two crossed flows, one of which is forced and the other gravitational, as follows:

An ascending flow of the product in the external peripheral portion of the mixing chamber
A descending flow at the center due to the effect of gravity.

The powder mixing is fast, homogenous and gentle, without overheating the mixed product.

The low peripheral speed makes these mixers particularly suitable for applications in hazardous areas in accordance with ATEX regulations 2014/34/UE e 1999/92/CE.

Main technical benefits

The rotation of the mixing shaft is carried out by means of a bevel gearmotor that ensure a high output of the entire kinematic chain and quiet operation.
Compared to common vertical screw mixers, in our vertical ribbon mixers the support of the mixing shaft is separate from the gearmotor allowing to change the latter without disassembling the mixing shaft, thus reducing maintenance time and costs.
The mixing shaft is supported and centered only on the top of the mixer thanks to a ribbed die-cast food grade aluminum frame that comprises two robustly spaced large ball bearings. This solution creates an effective joint for the mixing shaft.
The particular shape of the conical mixer body, allows a high quality of interior finish and ease of cleaning through its wide hatch. On request, they can be equipped with high pressure washing nozzles.

The shape of the mixer body and the adequate choice of plate thicknesses used will make it possible to place the mixer in a vacuum if it has to be filled by means of a pneumatic depression conveyor, thereby creating a continuous high capacity pneumatic conveyor system.
