Spiral Steel Silo
1. Thermal insulation, heat preservation properties
Grain temperature change gradient inside of the silo is lower than its outside, its not easy for condensation.
2. Storage safety
Low temperature, which is better for the storage stability of grain, maintain grains quality s and prolong storage time.
3. Lower cost
Comparing with cement Silo, the cost is lower, and wraped outside by some insulation materials (Polyurethane foam, rubber plastic sponge, glass fiber).
