The huge amount of paddy harvested is not only a guarantee of food security, but also poses an unprecedented challenge to the storage system. In the past, traditional storage methods such as bungalows and earthen warehouses were relied on. Although they were low-cost, they exposed many problems in the context of large-scale storage: temperature and humidity were difficult to accurately control, insects, mildew and rodents were frequent, the burden of manual management was heavy, and the space utilization efficiency was low, making it difficult to reduce the grain loss rate. Faced with this “extensive” problem, the “smart granary era” is emerging. With the application of new steel silos and automation and intelligent control technologies, we have the opportunity to equip paddy storage with a “smart brain” and achieve a comprehensive upgrade.

Advantages of steel silos for paddy storage
1. Large capacity and three-dimensional storage
Compared with the flat layout of bungalows, steel silos adopt a vertical three-dimensional stacking structure. The capacity of a single silo can reach thousands of tons or even tens of thousands of tons, which can achieve multiple storage capacity on the same floor area. This is especially important for enterprises with high land costs and limited expansion. Through the intensive layout of steel silos, the construction land can be greatly reduced, the construction cost and management radius can be reduced, and the “least land, the most grain” can be truly achieved.

2. Fast turnover and continuous operation
Steel silos are not only “capable”, but also “fast in and fast out”. Different types of silos can adopt a variety of discharging methods. Among them, small silos mostly use cone buckets to discharge materials, and the discharge is clean and residue-free; medium and large silos mostly use flat-bottomed silos or multi-point filling slopes in the silo. It is necessary to measure the best solution in many aspects based on actual needs. Combined with supporting electromechanical equipment, it can achieve 24-hour uninterrupted rapid storage and outbound operations. Flat warehouses mostly use mobile conveying machinery. Due to the weight limit of the equipment itself, the output is mostly around 100 tons/h. The steel silo is much larger in and out of the warehouse. At present, there are also cases of 1200tph. Compared with the flat warehouse that requires mobile conveying machinery for in and out of the warehouse, the steel silo is not only easy to operate, with less labor, but also has a larger output, especially showing the “accelerator” advantage during the peak period of logistics.

3. High strength and durability
The steel silo adopts a high-strength double-sided galvanized corrugated steel plate structure, with a zinc layer thickness of 275-600g/㎡. After professional anti-corrosion design and construction, it can withstand huge internal pressure and wind and snow loads, with a design life of 25 years, and a longer service life under good maintenance. The sturdy and durable structure not only reduces the efficiency loss caused by maintenance and shutdown, but also provides a reliable “infrastructure” for the long-term and stable operation of intelligent equipment.

4. Highly sealed, moisture-proof and insect-proof
The paddy steel silo adopts a galvanized corrugated plate assembly structure with excellent overall sealing. For paddy storage, this airtight performance is a great advantage: it effectively isolates external moisture and reduces the risk of grain getting damp and mildewed; the special treatment of the warehouse roof can circulate the whole warehouse for fumigation to prevent pests from breeding; the air inlet and outlet are equipped with anti-bird nets and warehouse eaves seals to reduce the chance of rodents and birds entering the warehouse. The polyurethane foam insulation outside the warehouse, combined with the use of grain coolers, can achieve low-temperature storage of paddy, which helps to maintain the quality of paddy. Through good sealing and insulation design, the use of steel plate silos to store grain can also extend the safe storage period of paddy. The environmental conditions can be carefully managed throughout the storage process, effectively maintaining the quality of paddy and reducing storage losses.

5. Convenient for large-scale logistics and transportation docking
Modern steel plate silo projects are usually designed with supporting equipment: scraper conveyors, bucket elevators; car loading and unloading ports; railway or port shipping facilities. This greatly improves the efficiency of paddy in and out of the warehouse, reduces loading and unloading losses, and facilitates seamless connection with markets, processing companies, export ports, etc.

Intelligent precision control
1. Intelligent inventory monitoring
A management problem is that the inventory is unclear and the operation is blind. The grain in the traditional flat warehouse bucket truck is calculated by the difference between the cumulative grain inflow and the cumulative outflow. The calculated warehouse inventory has the hidden danger of human fraud and has a large error with the actual inventory. It is necessary to use the warehouse camera and logistics in and out software to comprehensively stack the materials in the warehouse for supervision, and the management system is relatively complex.
The intelligent paddy steel plate warehouse in and out of the warehouse conveyor line is equipped with bulk grain scales, radar level meters and other advanced measuring equipment, which can monitor the paddy level and inventory in the warehouse in real time and accurately. The intelligent system automatically generates visual reports and inventory maps, allowing managers to grasp the inventory structure at a glance, scientifically plan the warehousing, outbound and warehouse reversing plans, and avoid congestion, backlog or waste caused by information asymmetry.

2 Intelligent linkage of equipment
The intelligent paddy steel plate warehouse not only “sees” and “thinks”?, but also “moves”. The core is the automated in-and-out warehouse system, including pneumatic conveying, belt conveying, automatic gates and intelligent distribution devices.
All equipment is seamlessly connected to the intelligent control center to achieve “one-click operation”. Whether it is the storage, out-of-warehouse or warehouse transfer of paddy, it can be completed automatically, efficiently and orderly, greatly reducing manual handling and waiting time. It greatly improves the turnover efficiency and ensures the continuity and timeliness of grain procurement.

The era of smart granaries is bringing a revolution to traditional rice storage. In particular, the intelligent control solution for rice steel silos (including project cases) realizes a truly large-capacity, high-efficiency, low-loss, low-manpower, and low-energy management model through the triple advantages of steel silos + intelligent systems + structured design. It helps companies reduce costs and increase efficiency, protect food security, and contribute to sustainable development. It is time to say goodbye to the “past tense” of manual extensive management and embrace the “ongoing” intelligent and efficient solutions.
