GEA has spent years researching and understanding the science of Intermediate Bullk Container (IBC) blending. An expertly designed blending cage and container geometry ensures homogenous product blending and our unique Prism™ technology is proven to improve blending times.
Robust construction ensures a long working life. The clamping cage provides a secure connection to the top and the bottom of the IBC, reducing mechanical stress during rotation and preventing damage.
Air-driven screw jacks ensure that the IBC remains fully clamped, even if machine utilities are lost. Positive IBC detection prevents any un-clamped blender operation and the cage rotation motor is braked, preventing any utility free movement and providing an emergency stop option.
The user friendly control system makes it simple to load blend recipes and print completed batch information. Blending speed is controlled using a variable speed drive and 21 CFR Part 11-compliant controls are available for electronic records.
The Pedestal Blender is available with the main pedestal housed in the technical area and the clamping cage in the process area. An airtight wall plate is supplied as a barrier between the two rooms. A smaller processing room results in reduced area and running costs, and technicians can access the pedestal from the technical side (without entering the GMP production area).
The Swinging Arm feature enables a wider range of IBC volumes to be handled in the same blender. When a smaller IBC is loaded into the blender, the spacer arms are swung out into the path of the IBC, bridging the height difference. The spacer arms maintain the IBC’s position at the centre of the rotation axis and reduce the clamping time.
Providing low shear mixing to a rotating IBC, turbulence is added to the tumbling product and the time to achieve a homogenous blend is reduced. When the IBC is loaded into the blender, the Prism™ is orientated at right angles to the rotation axis. As the IBC is rotated, the product is separated by the Prism™ and forced outwards to the corners of the container.
The Prism™ is particularly useful in dry blend processes, when IBC blending is the key process step. For dry blending or direct compression products, powders may be cohesive or flow poorly. Dry powders take noticeably longer to blend compared with free-flowing granular materials (such as the dispersion of magnesium stearate into a granulated batch), which blend easily in a relatively short period of time. The Prism™ is fully welded into the container body, and can be fully cleaned in place with the GEA Wash Station.
All GEA blenders can be fitted with PAT-compliant technologies such as Light Induced Fluorescence (LIF) or NIR systems. GEA uses these technologies to measure particle movement and in-process conditions during blending, providing a better understanding of powder behaviour, which improves R&D times and enhances process control. In the production environment, new product validation is quicker, and both productivity and containment are improved.
The technology works by using an NIR or LIF measuring head. Mounted on the rotating blending head with a viewing window on the wall of the IBC, an onboard data analyzer interprets the process data and sends it to a PC. Sophisticated software allows users to monitor the powder movement and detect the process end point.
Power is supplied through a specially designed slip ring, which guarantees a permanent and uninterrupted power source. Proximity switches in the blending head activate the system at the right time to trigger data acquisition.
The robust design of the clamping cage provides a secure connection at the top and bottom of the IBC, preventing premature mechanical fatigue and damage.
Pneumatically operated screw jacks provide a fail-safe clamping system that, unlike hydraulic versions, remain in place in the event of utility failure. The main support pedestal is designed to be housed in the technical area: an optional stainless steel design is available if the entire machine needs to be located in a cleanroom.
Our Single Pedestal machines can accommodate “Size 4” IBCs (up to 2000 L). The Double Pedestal Blender enables “Size 5” IBCs (up to 3000 L) to be used.
The GEA Pedestal Blender boasts a proven and durable design that offers low maintenance and a long working life; the perfect investment for today's pharmaceutical manufacturer.

The Post Hoist Blender provides users with the added benefit of being able to elevate the IBC after blending and directly discharge the contents into a downstream process. IBC-to-IBC milling and roller compaction, for example, are common applications for which the Post Hoist Blender provides a combined blending and handling solution.
The design of the Post Hoist Blender range is based entirely on our robust and proven post hoist design. The lifting carriage module of the post hoist is replaced with a blending head carriage; the remainder of the column design is the same as the standard post hoist range.
At the smaller end of the scale, our hoists can be used in R&D and pilot scale facilities. The PLB300 and PLB700 allow the use of 600 L (Size 2 and 3) and 1400 L (Size 4) IBCs, respectively.

A laboratory scale solution is available for 3-30 L volume blending, allowing for easy and repeatable scale-up to production scale. The Lab blender is available for both purchase and rental.
The SP30 allows containers ranging from 3-30 L to be tumble blended at a variety of speeds for variable times and/or revolutions. The unit can easily be manoeuvred within an R&D facility with the addition of a mobile trolley.
A range of interchangeable 3-30 L laboratory containers is available, allowing complete scale-up to our range of pilot-scale and production-scale containers. All of the containers feature a removable Blending PrismTM that allows the improved blending efficiency to be fully evaluated.
The SP30 NIR uses Near-Infrared technology to measure actual powder movement inside the IBC during the blending process. Real-time data acquisition provides a better understanding of powder formulation and behaviour, reduces the need for sampling and analysis and results in faster research times and improved process control.
