Live screw bottom for flake ice – 10681

Live screw bottom designed for flake ice and manufactured afterwards in BEMA. The application is the bottom of a silo containing the daily use of flace ice in a fish production factory. The silo receives flake is from the ice machines which can fill the silos during the night. The system is afterwards able to supply the factory with flake ice during the day, without requiring a large amount of ice machines to fulfill the daily demand.

Why is a live screw bottom a suitable solution for handling flake ice?

1. Flake ice can easily make bridge building. The complete coverage of screw feeders in the live screw bottom avoids this.
2. The live screw bottom has the possibility to secure a precise dosing of flake ice, which is required in the production facility
3. The live screw bottom ensure that all flake ice is transported out of the silo making it hygienic by its design

In this application the screw feeders deliver the flake ice to a transportation screw in the middle of the bottom. This means that this screw conveyor acts as a dosing screw conveyor, because it is 100% filled.

Placing the outlet screw in the middle of the live screw bottom has also the advantage:

• It is emptying of the silo without building a material layer to the outlet end
• The layer in the silo has an equal level

Which other types of bulk material is suitable for a live screw bottom?

1. Wood chips
2. Wood pellets
3. Powder with a light degree of stickyness
