System and a method for temporary storage and offloading of granular materials

A system for temporary storage and offloading of granular materials, the system comprising:

• a tank for storage of a granular material;
• an outlet pipe for offloading granular material from the tank;
• a suction head for offloading granular material from the tank;
• the suction head including an inside delimited by a lower end, an outlet for removing granular material from the suction head coupled to an end of the outlet pipe and sidewalls, extending from the lower end to the outlet;
• an inlet for the inflow of granular material into the suction head;
• one or more inner nozzles placed on an inside of the sidewalls and configured to emit a pressurized liquid, and to generate a helical flow within the suction head;
• one or more outer nozzles placed on an outside of the sidewalls and configured to generate a helical flow around the suction head;
• and
• wherein the one or more inner nozzles, are configured to generate a helical flow in the same direction as the one or more outer nozzles.
