DURABLE SILOS OF ALL SIZES FROM ANTTI
The new massive Iso-Antti grain silos are designed for the demanding conditions of the north. The volume of one Iso-Antti, depending on the number of layers and accessories, is between 732 and 1,911 cubic metres. The diametres of the Iso-Antti silos are 10.6 and 12.1 metres. For smaller grain storage needs, we still have traditional grain silos available in the size categories between 109 and 534 cubic metres.
Iso-Antti is designed with a big heart
Iso-Anttis are built strong and durable. The silos are designed to be as maintenance-free as possible. They are built to be sturdier and to last longer. Thanks to the special steel used for production, the silos can withstand a load of 917 kg/m3 (Eurocode). The roof is equipped with separate roof beams, thanks to which Finland’s winter conditions do not cause problems. The roof’s actuator load is 1,500 kg.
Iso-Antti grain silos are delivered as ready-made elements that are assembled by the installation team. Unlike the smaller silo models, Iso-Antti is erected using jacks as an aid. Assembling the elements is quick, thanks to the precisely measured parts. There is no need for special tools.
A large silo is cost-efficient
- more affordable cubic price for storage
- less need for conveyors
- efficient emptying (80 tonnes per hour, sweeper 60 tonnes per hour)
Iso-Antti offers a lot as standard equipment
The standard equipment of Iso-Antti grain silos includes person hatches on the roof and on the wall, wall ladders with back protectors, roof ladders with railings, and ventilation connections. The roof consists of a central cone, roof beams and one-piece roof blocks, which guarantee the mutual symmetry and strength of the silo and the roof. Iso-Antti grain silos are emptied efficiently with Sveaverken’s horizontal and vertical augers. The auger system is delivered in full.
A soil survey and a level concrete floor are required
The foundations of Iso-Antti silos are cast from concrete on the ground, and the base of the concrete floor is flat. Regardless of the soil, a soil survey must be done for the grain silo. The drain auger is embedded in the foundations. On a ventilated floor, embedding is not required.
Ventilated floor as an accessory
The ventilated floor allows for the grain mass to be ventilated with a ventilation fan, if necessary.
- Perforated board floor, the lower space of which is pressurised
- Ventilation fan, 11 kW high pressure fan
- Height of the ventilated floor 351 mm, free space 306 mm
Filling
Supports are needed for the drive head and the conveyor for filling. There is a grain pipe support kit available for filling with a grain pipe.
Efficient emptying
Emptying takes place with Sveaverken’s horizontal and vertical augers. The auger system is delivered in full. The delivery includes a cover for the horizontal auger and a rain cover for the Sweeper motor. Electrification and control of the motors are not included in the delivery.
- Horizontal and vertical auger 80 tonnes per hour
- The loading height of the vertical auger 5.7 m
- Sweeper 60 tonnes per hour for final emptying (1+3 emptying openings)
Temperature monitoring as an accessory
The grain temperature is tracked with temperature monitoring. If the temperature in the silo rises, the ventilation fan is turned on to cool the grain.
- 12 measurement points (4 sensors in three cables)
- Wireless Bluetooth connection for Android phone
