paddy hopper bottom silo Introduction

A paddy hopper bottom silo is a specialized storage container designed for the storage of paddy grains, featuring a hopper-shaped bottom that facilitates the flow and discharge of the grains. This type of silo is suitable for large-scale storage of paddys and is commonly found in grain depots, rice mills, and agricultural cooperatives. A paddy hopper bottom silo is a critical facility to ensure that paddys are properly preserved after harvest until they are processed or sold.

The structure of the paddy hopper bottom silo

Top Cover

The top cover seals the top of the silo, preventing external contaminants from entering and protecting the paddy rice from weather conditions. Some covers also have ventilation systems to maintain internal air circulation.


The cylinder is the main body 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 paddy rice to flow smoothly towards the discharge outlet. This design helps prevent accumulation and clogging of the rice inside the silo.

Discharge Outlet

Located at the lowest point of the conical bottom, the discharge outlet typically features control valves or gates to regulate the flow rate and quantity of paddy 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 are designed to bear the total weight of the silo and its contents.

Ventilation System

Some advanced paddy 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 paddy hopper bottom silo

Efficient Storage and Handling

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

Reduced Waste

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

Ease of Cleaning and Maintenance

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

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 and prevents 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.

paddy 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.
