Dry Bulk Containers

In brief

A dry bulk container is a closed shipping container for dry, loose bulk goods. The material is usually loaded through hatches in the roof and discharged via openings at the end.

What are the advantages of a dry bulk container?

The container allows for the transport of loose goods without the need for individual sacks or other small packaging. This simplifies the loading and unloading of large quantities.

Further advantages include:

  • Protected transport of dry bulk goods
  • Loading via roof hatches
  • Controlled discharge via outlet openings
  • Transport by ship, rail, and truck
  • Reduced packaging material
  • Integration into existing container logistics

What is a dry bulk container used for?

Dry bulk containers are suitable for dry, free-flowing goods. Typical loads include:

  • Grain and animal feed
  • Plastic granules
  • Powders and minerals
  • Fertilizers
  • Sugar, flour, and other dry food products
  • Industrial raw materials

Suitability must be assessed for each product individually. Factors such as moisture, particle size, flow characteristics, and potential dust generation must be taken into account.

How are dry bulk containers loaded and unloaded?

Loading is typically carried out through circular hatches in the roof, using silos, conveyor systems, or hoses.

For unloading, the container is often tilted. The bulk material then flows out through special openings in the doors or at the front end. Depending on the design, pneumatic unloading may also be possible.

Terminology: Dry bulk, bulk liners, and tank containers

  • Dry bulk container: A specially built container with fixed loading and discharge openings
  • Bulk liner: A flexible inner lining that allows a standard container to be used for specific bulk goods
  • Tank container: A closed tank for liquids, gases, or liquid food products
  • Open top container: A container with an open roof for bulky goods or loading by crane

What needs to be considered before transport?

The container and its interior must be clean, dry, and suitable for the specific bulk material. Food products require a correspondingly hygienic setup.

The maximum gross weight is also important. With heavy materials, the maximum payload may be reached before the entire volume is filled. Furthermore, the load must be distributed evenly.

Additional protection and transport regulations apply to dusty, hazardous, or sensitive materials.

Frequently Asked Questions (FAQ)

What does dry bulk mean?

Dry bulk refers to dry, loose cargo. This includes free-flowing goods that are transported in large quantities without packaging.

Is a dry bulk container suitable for liquids?

No. Tank containers or other appropriate vessels are used for liquids.

What sizes are common?

Dry bulk containers are commonly available in 20-foot sizes. Other sizes and custom designs are also possible.

Can any type of bulk cargo be transported in them?

No. Suitability depends on the properties of the product and the container's specifications.

Is a dry bulk container suitable for food products?

Only if the material, interior, cleaning, and documentation meet the applicable requirements for the specific food product.

Can a standard container be used as a bulk container?

For suitable products, a standard container can be equipped with a bulk liner. However, this is not a purpose-built dry bulk container.
