PerMix Fluidized Zone Mixer

The PerMix PFB series Fluidized Bed Mixer / Twin Shaft Paddle Mixer Non-gravity Mixerconsists of paddles with special angles that are mounted on twin shafts in a ‘W’ shaped trough. During operation, the two shafts are rotating in opposite directions.

The paddles sweep the entire bottom of both troughs, and materials are lifted floating between the two shafts (as zero-gravity zone) by the centrifugal force generated by the paddles. At this weightless zone, mixing of materials of different density is easy and fast because material particle can move freely and randomly, regardless of particle size and density. This brings a rapid and highly homogenous mixing.

1. Very fast mixing to supply a typical mixing time from 10 seconds to only 1 minute
2. Free particle movement
3.  Minimal heat and low shear for shear and heat sensitive materials (Due to the fact that low friction without shear in this non-gravity zone is generated, this makes the PerMix PFB series Fluidized Bed Mixer / Twin Shaft Paddle Mixer an ideal machine for fragile products that can’t tolerate rough handling, even flakes or spray dried bodies remaining intact after mixing.)
4. Easy cleaning and hygienic design with minimal blind corners
5. Low maintenance
6. Big bomb bay door for fast discharging & reduced segregation
7. Liquid addition by spray balls, nozzles, or dripping pipes
8. Leading edges of the ribbons can be coated by Tungsten Carbide for very abrasive materials.
9. Intensive choppers to break lumps
10. Various drive system (single motor/gearbox with chain; dual motor/gearbox, single motor with dual gearbox)

The PerMix Single Shaft Fluidized Bed Mixer, just like the Twin Shaft Paddle Mixer, is a fast mixer with high efficiency,  and low/no shear, which can also be known as Fluidizing Mixer, Fluidized Zone Mixer, Non-gravity Mixer or Zero-gravity Mixer.

The Fluidized Bed Mixer / Single & Twin Shaft Paddle Mixer is applied to prepare a homogeneous mixture despite of particle size, shape and density. When the small amount of powder additives or liquid is required to be added into the bulk material, Fluidized Bed Mixer / Single or Twin Shaft Paddle Mixers are able to achieve fast and precision mixing with high capacity.

The PerMix PFB & PFBS series Fluidized Bed Mixer / Signle or Twin Shaft Paddle Mixer Non-gravity Mixer consists of paddles with special angles that are mounted on shafts in a ‘U’ or ‘W’ shaped trough.

During operation, the shafts are rotating at high speeds, and in the Dual Shaft units, spin in opposite directions. The paddles sweep the entire bottom of both the trough, and materials are lifted floating between the shafts (as zero-gravity zone) by the centrifugal force generated by the paddles.

At this weightless zone, mixing of materials of different density is easy and fast because material particle can move freely and randomly, regardless of particle size and density. This brings a rapid and highly homogenous mixing.

Integrated Loading, Unloading, and Material Handling Solutions by PerMix & Fuxion MME

Efficient production begins and ends with seamless material movement. PerMix UK, in partnership with Fuxion MME, delivers a complete, integrated approach to loading, dosing, and discharging systems for powder, paste, and liquid processing. Together, we offer turnkey solutions that connect mixing, material handling, and packaging into one smart, automated flow.

Loading Options for PerMix Mixers

PerMix mixers can be configured with a variety of loading systems depending on your process, ingredients, and production scale:

1. Manual Loading:
For small batches and R&D applications, mixers can be top-loaded using manual bag dumping stations with integrated dust extraction and sifting options.

2. Vacuum Loading Systems:
Vacuum conveyors draw powders, granules, or flakes directly from drums, totes, or silos into the mixer, ensuring a sealed, dust-free environment—ideal for pharmaceutical, food, and chemical production.

3. Pneumatic Conveying Systems:
High-efficiency conveying lines move powders and pellets from bulk silos or intermediate bulk containers (IBCs) directly into mixers. Available in both dense phase and dilute phase configurations, these systems reduce contamination risk and improve product consistency.

4. Screw or Auger Feed Systems:
When handling cohesive or heavy powders, a screw feeder ensures precise, controlled delivery into the mixer—perfect for gravimetric or volumetric dosing applications.

5. Big Bag / FIBC Discharge Systems:
For large-scale operations, PerMix integrates bulk bag dischargers with hoists or frames that connect directly to the mixer inlet. Combined with dust-tight docking systems, they provide hygienic and efficient ingredient handling.

Unloading & Discharge Options

After the mixing process, PerMix mixers can be equipped with several discharge configurations to suit your downstream process:

1. Bottom Valve Discharge:
Fast, gravity-assisted emptying for free-flowing materials.

2. Auger or Screw Discharge:
For cohesive or slow-moving powders, a screw discharge system ensures consistent flow into hoppers, conveyors, or packaging machines.

3. Tilting Discharge Systems:
PerMix tilting mixers allow complete discharge for batch changeovers or washdown, minimizing residue and cleaning time—ideal for sanitary or multi-flavor production environments.

4. Direct Filling Integration:
Mixers can discharge directly into Fuxion MME filling and packaging equipment, reducing handling steps and maximizing process efficiency.

Micro & Macro Dosing Systems

Precision is everything when it comes to quality control and repeatability. Fuxion MME’s dosing solutions complement PerMix mixers perfectly, offering both:

• Micro-Dosing Systems for ingredients like vitamins, colorants, enzymes, and additives, with accuracies up to ±0.5%.

• Macro-Dosing Systems for bulk powders, starches, or proteins with integrated load cell monitoring and recipe-based automation.

These dosing modules can feed directly into PerMix mixers or combine with vacuum or screw conveyors for automated ingredient addition.

Bulk Material Handling Integration

The PerMix–Fuxion alliance delivers a complete bulk material handling ecosystem, including:

• Big bag fillers and unloaders

• Pneumatic and mechanical conveyors

• Gain-in-weight and loss-in-weight feeders

• Dust-free bag dump stations

• Storage silos and intermediate holding tanks

• Bucket elevators and vibratory feeders

This holistic approach ensures ingredient traceability, batch integrity, and consistent throughput from raw material to finished product.

Filling, Packaging, and End-of-Line Solutions

To complete the process, Fuxion MME offers a full range of downstream equipment that pairs seamlessly with PerMix mixers and dryers:

• Auger fillers, volumetric fillers, and liquid fillers

• Vertical and horizontal form-fill-seal systems

• Jar, drum, and pouch filling systems

• Cappers, sealers, and labeling lines

• Weighing, checkweighing, and metal detection stations

• Robotic palletizing and stretch wrapping units

Whether you’re packaging powders, pastes, or granulated materials, these solutions create an unbroken line from mixing to market-ready packaging.
