Key takeaways
Intermediate bulk containers occupy a specific niche in material handling: too much material for a drum, too little for a silo, and it has to move around the plant rather than sit in one place. That combination describes a large share of production in food, pharmaceutical and speciality chemical manufacturing, which is why IBCs are everywhere in those industries.
The complication is that the term covers two entirely different products bought by different people for different reasons. Sorting that out first makes everything else easier.
Two Products, One Acronym
Say IBC in a chemical distribution business and it means a one thousand litre plastic bottle inside a steel cage on a pallet base, holding a liquid, moved by forklift, shipped between sites. Say IBC in a pharmaceutical or food plant and it means a welded stainless steel vessel holding powder or granules, moving between process stages inside the same building, cleaned and reused indefinitely.
| Composite or plastic IBC tote | Stainless steel process IBC | |
|---|---|---|
| Typical contents | Liquids and low viscosity chemicals | Powders, granules, tablets, capsules and bulk solids |
| Standard capacity | Commonly around 1000 litres | Ranging from 30 to 2000 litres |
| Construction | Polyethylene bottle inside a steel cage on a pallet base | Welded stainless steel, SS304 or SS316 |
| Reuse | Limited reuse, frequently single-trip or reconditioned | Reused indefinitely with a validated wash cycle |
| Where it is used | Chemical distribution, transport and site storage | Inside the plant, between process stages |
| Cleaning | Reconditioning by a third party or disposal | In-house washing machine with documented cycles |
Both are genuinely called intermediate bulk containers and both are correct. Everything below concerns the second, the stainless process IBC used for bulk solids inside manufacturing plants, because that is where the engineering decisions are and where the equipment ecosystem sits.
What an IBC Actually Does in a Plant
The obvious answer is storage. The more useful answer is that an IBC lets material move through a plant without being repeatedly opened, decanted and re-handled.
In a multi-product facility, material is charged into an intermediate bulk carrier once, and from that point the container itself becomes the process vessel. It can be lifted and docked over a mixer, blended while sealed, discharged into the next stage, weighed, and moved to the next operation, all without the powder being exposed to the room or to an operator.
That containment is the real value, and it delivers three separate benefits at once. Product is protected from contamination and from ambient moisture. Operators are protected from dust exposure, which matters enormously with active pharmaceutical ingredients. And the plant is protected from cross-contamination between products, because each batch travels in its own dedicated vessel rather than through shared fixed pipework.
The Handling Ecosystem
An IBC on its own is a container. What makes the approach work is the equipment built around it, and a plant buying IBCs without planning that equipment ends up with expensive vessels it moves by hand.
A column lift raises and docks IBCs of up to 2000 litres precisely over the receiving equipment, holding position even during a power loss. This is what turns gravity discharge from a manual handling problem into a controlled operation.
Design Features That Determine Whether It Works
Internal geometry and dead zones
The single most important characteristic. Any internal corner, weld ridge or shallow angle where powder can settle and remain is a dead zone, and dead zones defeat the entire purpose. They hold residue through discharge, they survive washing, and they become a cross-contamination route. Properly designed IBCs have continuous internal surfaces and discharge geometry steep enough that the container empties completely under gravity.
Closure and gasketing
The lid is where containment succeeds or fails. A gasketed top lid keeps product in and moisture out during transport and tumbling. Where the container will be inverted for blending, the seal has to hold under the full weight of the contents rather than merely resting closed.
Handling interfaces
Locating lugs sized to the lifting arm, castors for floor movement, and a stable base that will not rock when docked. These sound minor and are the difference between a container that integrates with the plant and one that needs two operators every time it moves.
Material of construction
SS304 covers most food and general duty. SS316 is specified where the product is acidic, chloride-bearing or otherwise corrosive, and is the usual choice for pharmaceutical work. Surface finish matters alongside grade, because a rough internal surface holds residue however good the geometry is.
Capacities and Specification
| Parameter | Specification |
|---|---|
| Model code | SEDI-IBC |
| Capacities | 30, 100, 500, 1000 and 2000 litres, customisable |
| Materials of construction | SS304 or SS316 |
| Build standard | Hygienic, GMP built |
| Internal geometry | No dead zones |
| Closure | Top lid gasket for minimal leakage |
| Mobility | Castor-mounted trolley |
| Handling interface | Locating lugs to suit lifting arm |
| Options | Weighing scale, automation for upstream and downstream processes |
| Related equipment | IBC Column Lift, IBC Blender, IBC Washing Machine |
The capacity range is worth noting for what it implies. A 30 litre container and a 2000 litre container are the same product family serving very different roles: the small ones for high value pharmaceutical intermediates and sampling, the large ones for bulk food ingredients. Plants frequently run several sizes, which makes handling equipment compatibility across the range a real specification point.
“The most important specification in an IBC is often invisible: internal geometry that eliminates dead zones, ensures complete discharge, and prevents cross-contamination between products.”

Specification Points That Matter
Materials Handled and Industries
Cybernetik IBCs handle powders, granules and bulk solids including sugar, dextrose, starch, salt, grains, beans, seeds, popcorn, food additives, chemicals, tablets, capsules and active pharmaceutical ingredients, across food, pharmaceutical and chemical manufacturing.
The breadth of that list is the point. A container carrying capsules one week and starch the next is only possible because of the washing cycle and the absence of dead zones. Where a plant runs a single product continuously, an IBC is usually the wrong answer.
IBC, Silo, Drum or Big Bag
IBCs are one of four ways to hold bulk solids between process stages, and the choice follows from product variety and volume rather than from preference.
| Storage option | Typical capacity | Suits | Limitation |
|---|---|---|---|
| Stainless IBC | 30 to 2000 litres | Multi-product plants, campaign manufacturing, contained transfer | Capital cost per unit and the handling equipment it requires |
| Storage silo | 1 to 50 cubic metres | One product at high volume in continuous production | Fixed installation dedicated to a single material |
| Drum | Around 200 litres | Small batches, samples, high value materials | Manual handling and a large number of units to manage |
| Big bag or FIBC | 500 to 1500 kg | Incoming bulk deliveries | Dust exposure at opening, limited reuse, no rigid containment |
The clearest dividing line is product variety. One product at volume in continuous production belongs in a storage silo, which handles 1 to 50 cubic metres in fixed installation. Many products in campaign runs belong in IBCs, where each batch keeps its own vessel and cross-contamination is managed by washing rather than by flushing shared lines.
IBC Systems from Cybernetik
Cybernetik builds intermediate bulk carriers alongside the full handling ecosystem around them, which means the container, the lift, the blender, the washing machine and the discharge interface are engineered to work together rather than sourced separately and made to fit.
That range sits within a wider powder handling portfolio covering storage silos, valves, screw and belt conveying, sifting, grinding, mixing and packing equipment, all under process automation solutions.
Cybernetik has operated for more than three decades, is headquartered in Pune with additional facilities in Gujarat and Raigad and international offices in the United States and UAE, and has installed over 6,000 systems across 30 plus countries, including more than 400 custom automation solutions. With over 600 employees and divisions spanning Process Automation, Packaging Automation, CleanTech, Extraction, Labs and Defence, an IBC is specified with knowledge of every stage it will pass through.
