Apart from pressure containers, we can also use pressureless containers for dry bulk, These are containers that can be discharged without any pressure, For the discharge of pressureless containers we make use, among others, of a sluice through which the content can be discharged with the help of air. The advantage of such containers is that they are less expensive. However, this type of container is only suitable for a limited number of products.
A third alternative for intermodal transports of dry bulk is a bag-in-box system. This system consists of a special 30Ft container that is equipped with manholes at the top and discharge valve at the bottom of the doors. A liner bag is then placed in these containers. This container is based on the same discharging principle as that of pressureless containers a discharge sluis or rotary valve is used here as well.
