Paddy cone bottom silo Introduction

The paddy cone bottom silo is a specially designed storage device, typically made of galvanized corrugated panels, offering good moisture resistance and used for storing granular grain products such as rice. The bottom of this silo is designed with a conical shape, which facilitates the self-flow unloading of grain under the influence of gravity, thereby improving the efficiency of storage and retrieval.

Features of paddy cone bottom silo

Conical Bottom Design

The Paddy cone-bottom silo features a conical bottom that aids in the smooth and self-flowing extraction of granular grains like rice, reducing the need for manual intervention and increasing the efficiency of retrieval.

Galvanized Corrugated Panel Material

Constructed with galvanized corrugated panels, the silo material offers excellent corrosion resistance and moisture protection, safeguarding the stored rice from environmental factors and prolonging its shelf life.

Structural Stability

The cone-bottom silo is highly stable, capable of withstanding substantial grain weights and protecting against natural disasters such as wind, rain, and snow.

Ease of Cleaning and Maintenance

The silo’s interior walls are smooth, free of steps or flanges, which facilitates easy cleaning and maintenance, ensuring a sanitary environment for grain storage.

Efficient Storage Management

The Paddy cone-bottom silo enables centralized grain storage and management. With modern storage management systems, it effectively monitors the storage condition of the grain, preventing spoilage and pest infestation.


The design of the cone-bottom silo can be adjusted to accommodate different types of grain and storage requirements. For instance, the size of the cone angle can be tailored to the flowability of the grain, making it suitable for various grain storage needs.

Environmental and Energy Efficiency

The design of the Paddy cone-bottom silo helps to minimize grain loss during storage. When combined with the use of drying towers and ventilation equipment, it further reduces energy consumption, promoting green storage practices.


The Paddy cone-bottom silo can be interconnected with adjacent silos through transfer devices, making it convenient for the mass transfer and transportation of grain, thereby enhancing overall logistics efficiency.

Paddy Cone bottom silo structure


This is the topmost part of the silo, typically designed to withstand certain loads and sometimes includes access for maintenance and repair operations.


The walls form the main body of the silo and are usually modeled as either curved or straight walls. For taller deep silos, the walls are modeled in layers to ensure accurate calculation of the storage load and structural stability.


The base includes the conical bottom, which facilitates the self-flow unloading of granular grains like rice. The base may also feature ring beams and support structures to enhance the load-bearing capacity of the silo.


Located at the bottom of the base, the hopper is part of the conical structure and aids in the smooth flow of grain out of the silo. The design of the hopper is crucial for ensuring efficient extraction of grain from the silo.


This includes the base and any underground structures that provide stable support for the silo. The foundation design takes into account geological conditions and structural loads to ensure the stability of the entire silo.

Elevated Structures

If present in the silo design, these structures provide additional working platforms or support for equipment such as ventilation systems and monitoring devices.

Supporting Structures

These connect the silo body to the foundation and include columns, beams, etc., ensuring the overall stability of the silo and the proper transmission of loads.

Advantages of Paddy cone bottom silo

Good Self-Flowing Property

The conical design of the silo allows rice to naturally form a slope within the silo. When it’s time for discharge, the rice can smoothly slide down relying on its own gravity, without the need for additional power, greatly simplifying the discharge process and improving the efficiency of discharge.

Reduced Residue

Compared to flat-bottom silos, the conical structure effectively reduces the accumulation and residue of rice at the bottom, almost achieving “zero dead corners,” reducing material waste and improving the overall storage utilization rate.

Preventing Arching

The conical bottom helps to disperse the pressure of rice accumulation, reducing local stress concentration and lowering the risk of rice arching due to long-term static storage, ensuring even distribution of the material within the silo for smooth subsequent discharge.

Enhanced Ventilation

The bottom of the conical silo is typically designed with ventilation openings or ducts, and the conical shape facilitates even air circulation through the rice pile, improving the efficiency of the ventilation system and helping to keep the rice dry, preventing mold and overheating.

Reducing Pest Infestation

Due to the absence of accumulated material at the bottom of the conical silo, there are fewer damp and dark corners, reducing the chances of pest and microbial breeding, which is beneficial for maintaining the quality of the rice.

Ease of Cleaning

The conical structure results in a smaller bottom area of the silo and no dead corners, making cleaning work easier. Whether it’s mechanical sweeping or manual clearing, it can be efficiently accomplished, reducing maintenance costs.

Optimized Space Utilization

Although the conical silo occupies some space at the bottom, its good self-flowing and low residue characteristics allow for more effective use of the silo volume overall, especially in scenarios requiring frequent discharge, where its comprehensive economic benefits are more prominent.

Enhanced Structural Stability

The conical design lowers the center of gravity of the silo, enhancing the overall structural stability. This is particularly effective in resisting external forces during extreme weather conditions such as earthquakes and strong winds, ensuring the safety of the silo.

Application scope of Paddy cone 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.

Paddy cone 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.
