Features of Rice Hopper Bottom Silo

Specialized Storage

Specifically designed for storing rice, meeting the specific storage characteristics and requirements of the grain.

Hopper Bottom Design

The conical bottom design helps rice flow smoothly, reducing accumulation and stagnation during storage.

Capacity Options

Available in a range of sizes to accommodate varying storage needs.

Structural Stability

Built with a robust structure capable of withstanding the weight of large quantities of rice.

Loading and Unloading Efficiency

Equipped with an efficient conveying system for quick loading and unloading of rice.


Excellent sealing performance to protect rice from moisture, contamination, and pests.


Constructed from durable materials such as carbon steel or stainless steel for long-term stability and use.

Ease of Maintenance

Designed with maintenance in mind for easy routine inspections and servicing.

Automated Control

May include automated control systems to enhance storage efficiency and reduce labor costs.

The structure of the rice hopper bottom silo

Top Cover

The top cover seals the silo, preventing dust and debris from entering and protecting the rice from moisture and external contamination. Some covers have ventilation features to maintain internal air circulation.


The cylinder is the main part of the silo, usually made of high-strength steel or other durable materials to ensure structural stability and durability. The size and capacity of the cylinder can be customized based on specific needs.

Conical Bottom (Hopper Bottom)

The conical bottom design allows rice to flow smoothly towards the discharge outlet. This part typically uses smooth materials and appropriate angles to prevent clogging and accumulation of rice.

Discharge Outlet

Located at the lowest point of the conical bottom, the discharge outlet usually features control valves or gates to regulate the flow rate and quantity of rice. Modern discharge outlets may include automated control systems for precise flow control.

Supports and Foundation

Supports and foundation provide stability and support for the silo, ensuring it stands safely and reliably on the ground. The supports are typically made of steel and designed to bear the total weight of the silo and its contents.

Ventilation System

Some advanced rice hopper bottom silos are equipped with ventilation systems to control internal temperature and humidity, preventing rice spoilage. The ventilation system may include fans, air filters, and ventilation ducts.

Monitoring and Control System

Modern silos often come with sensors and control systems that monitor internal parameters such as temperature, humidity, and material level. These systems can connect to computers or mobile devices for remote monitoring and management.

Cleaning and Maintenance Facilities

The silo may have cleaning and maintenance facilities such as manhole covers or access doors, allowing staff to enter the silo for cleaning and maintenance.

The main advantages of a rice hopper bottom silo include

Efficient Storage and Handling

The conical bottom design ensures the smooth flow of rice, reducing clogging and accumulation.

Reduced Waste

The bottom design helps fully empty the silo, minimizing residue and increasing the utilization rate of the rice.

Ease of Cleaning and Maintenance

The structural design makes cleaning and maintenance more convenient, maintaining hygiene and ensuring rice quality.

Improved Operational Efficiency

Automated control systems and sensors enhance operational efficiency, reducing manual intervention and labor costs.

Durability and Stability

The use of high-strength materials ensures long-term durability and stability of the silo.

Environmental Control

Equipped with ventilation and temperature and humidity control systems, the silo maintains optimal storage conditions, preventing rice spoilage.


The stable support structure ensures the silo stands securely, reducing the risk of accidents.


By optimizing storage and handling processes, reducing waste, and improving efficiency, the silo achieves long-term cost savings.

Application scope of rice hopper bottom silo

Coban Silo is widely used for grain storage such as wheatcornsoybeanpaddyricesoybean mealbarleymaltsunflower seedsrapeseedpeanutsflour, and other powder materials, oat, special Silo, and seeds, etc. Steel silo products include 100 ton300 ton500 ton1000 ton2000 ton3000 ton, 5000 ton and 10000 ton steel silo as well as metal silospiral silo and galvanized silo.

rice hopper 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.
