Advantages of flour flat bottom silo

Efficient storage

The flat-bottom design maximizes space utilization, achieving the maximum storage capacity for flour.

Easy discharge

The flat-bottom design facilitates uniform flow of flour, reducing blockages and retention, ensuring smooth discharge.

Structural stability

The design of the flat-bottom silo evenly distributes the weight of the flour, providing excellent stability.

Reduction of grading

The flat-bottom design helps reduce automatic grading of flour based on particle size and density, ensuring uniform quality within storage batches.

Customizable design

Flour flat-bottom silos can be customized according to specific storage requirements, including size, capacity, and additional features such as ventilation systems.


Typically constructed with durable building materials such as stainless steel or steel plates with special coatings to resist acidic substances in flour.

Environmental and safety

Equipped with ventilation systems to reduce flour dust accumulation, preventing self-ignition and explosion risks.


Although initial investment may be higher, the long-term durability and low maintenance costs make it economically beneficial.


Future expansion needs are considered in the design, allowing for expansion based on increased storage volume.

Application scope of flour flat bottom silo

Coban  Silo is widely used for grain storage such as wheat, corn, soybean, paddy, rice, soybean meal, barley, malt, sunflower seeds, rapeseed, peanuts, flour, and other powder materials, oat, special Silo, and seeds, etc.

flour flat bottom silo technical parameters

Scientifically speaking, the Silo capacity should be measured with volume (m3). Even in the same grain Silo, the storage tons will be different for different grains with different densities. The following table is calculated based on a  Silo density of 0.75kg/m3, and surely HKB customizes  Silo systems unique for you.
