Ice Where and When It’s Needed

Once ice is produced and stored, most ice plants are equipped with systems to automatically deliver ice to remote icing stations or other use points. North Star can draw on decades of experience to assist customers in designing the most efficient and cost effective options for ice delivery.

North Star ice delivery is provided by either screw conveyors or pneumatic systems, both of which can provide delivery of up to 40 tons (36 MT) of ice per hour to one or more use points. All deliveries of ice from the storage bin and from the delivery system can be remotely controlled and volumetrically metered. Ice deliveries can be recorded on digital counters, within 2% accuracy at the storage bin, the remote stations, and the control centers. The electrical operation of the entire delivery system is controlled by the central ice plant control panel.

SCREW CONVEYING SYSTEMS

• Most economical for horizontal deliveries of up to approximately 150 feet (45.7 meters).
• Can be installed at angles up to 30 degrees from horizontal.
• Manual or automatic curved slide gates provide intermediate in-line discharge points.
• Available in either standard hot dip galvanized or optional stainless steel finish, with or without factory-applied insulation.
• Telescoping chutes or hoses can be provided at the conveyor discharge to accommodate variations in tidal elevation, placement, or size of the ice container (vessel, railroad car, or truck.)

PNEUMATIC DELIVERY SYSTEMS

• Most economical when conveying ice over long distances, when multiple icing stations are required, when the ice must be greatly elevated, or when ice must be delivered at high velocity.
• Standard systems discharge ice up to 500 feet (152 meters) away from the storage bin. For longer distances contact North Star
• Automatic diverter valves are available - electric lineal actuated or air actuated to provide multiple delivery points.
• Provides high velocity discharge to trucks, boats or railcars; or low velocity, gravity discharge using a cyclone receiver for totes, case ice dispensers or buffer tanks.

North Star has successfully conveyed ice to an operating concrete batch plant over 1,200 feet (366 meters) from the ice plant at Libby Dam, Montana. Automatic pneumatic delivery systems of 400 to 800 feet (122 to 244 meters) distance in multiple directions from the ice plant are serving the chemical, concrete cooling, and fishing industries. The discharge rate of the ice storage bin and capacity of the delivery system are balanced to allow continuous or intermittent operation and delivery at 8 to 40 tons per hour per storage unit.
