Hanoi, Vietnam LIAONING QIUSHI Silo Equipment Engineering Co., Ltd., a global leader in grain storage solutions, has successfully completed the construction and commissioning of a 3,000 ton specialized paddy silo in Vietnam’s Mekong Delta region. The project, tailored to address the local agricultural sector’s need for efficient, moisture controlled paddy storage, marks a key milestone in enhancing Vietnam’s post-harvest grain management capabilities and aligns with the country’s goal of reducing annual paddy loss rates.
Vietnam is one of the world’s top rice exporters, with the Mekong Delta contributing over 50% of the country’s total paddy output. However, traditional storage methods such as open-air drying yards and makeshift warehouses have long plagued local farmers and grain cooperatives: high humidity (average annual relative humidity of 75%–85%) and frequent monsoons lead to paddy mold growth and moisture absorption, resulting in an estimated 8%–12% annual paddy loss.
The 3,000-ton silo, located in Can Tho Province (a core paddy-producing area in the Mekong Delta), was designed by LIAONING QIUSHI to tackle these region-specific challenges. “Vietnam’s paddy storage needs are unique high moisture resistance, efficient ventilation, and compatibility with local harvesting cycles were non-negotiable requirements,” said Mr. Alex Zhang, Project Manager at LIAONING QIUSHI. “Our team spent six months conducting on-site surveys, analyzing local climate data, and collaborating with the client—a regional agricultural cooperative—to ensure every detail of the silo met their practical needs.”
Unlike generic grain silos, LIAONING QIUSHI’s 3,000-ton facility incorporates specialized technologies to protect paddy’s delicate structure and prevent quality degradation critical for maintaining rice’s market value, especially for export:
Paddy’s high initial moisture content (often 20%–25% post-harvest) makes it prone to spoilage if not managed properly. The silo is equipped with LIAONING QIUSHI’s proprietary multi-layered ventilation system, which uses temperature- and humidity-sensitive sensors to trigger automated airflow adjustments. “During the rainy season, the system can reduce paddy moisture from 18% to the safe storage threshold of 13%–14% within 72 hours, without over-drying the grain,” explained Mr. Zhang. This feature is particularly vital for the Mekong Delta, where monsoons can delay open-air drying and leave paddy vulnerable to moisture damage.
The silo’s exterior and interior components are built with hot-dip galvanized steel (zinc coating ≥ 275g/m²) and anticorrosion paint, specially formulated to withstand Vietnam’s high humidity and salt-laden air (a common issue in delta regions). “Traditional steel silos in Vietnam often develop rust within 3–5 years, but our design ensures a 15+ year service life with minimal maintenance,” noted Mr. Pham Minh Tri, Technical Director of the client cooperative. “This long-term durability means we won’t have to worry about costly repairs interrupting our storage cycles.”
To help the cooperative track paddy condition remotely, the silo is integrated with LIAONING QIUSHI’s Smart Grain Management System. Via a mobile app or web portal, users can monitor real time data including silo temperature (segmented into 5 layers to detect hot spots), humidity, and paddy moisture content. The system also sends automatic alerts for anomalies, such as sudden humidity spikes or localized heating early warnings that prevent mold growth and insect infestations.
The Mekong Delta’s paddy harvests are concentrated in two annual cycles (May–June and November–December), requiring fast silo throughput to avoid post-harvest delays. LIAONING QIUSHI equipped the project with a high-capacity conveyor system (15 tons/hour) and a automated discharge valve, allowing the cooperative to fill the silo in 5 days and empty it in 4 days 30% faster than manual loading methods. “During last November’s harvest, we used to struggle with storing 1,000 tons of paddy; now, with this silo, we can handle 3,000 tons without rushing or risking quality,” said Mr. Tri.paddy silopaddy silopaddy silopaddy silopaddy silopaddy silopaddy silopaddy silo
Despite challenges such as tropical rainstorms and logistics delays for equipment transport, LIAONING QIUSHI’s project team completed the silo in just 12 months on schedule and within the client’s budget. The process included three key phases:Grain SilosGrain SilosGrain SilosGrain SilosGrain SilosGrain SilosGrain Silos
Pre-Construction Preparation (3 months): Soil testing, climate data analysis, and design finalization to ensure the silo’s location and structure matched local geological and climatic conditions.
Main Construction (8 months): Modular construction was adopted to reduce the impact of weather on on-site work. A dedicated technical team supervised quality control throughout the process to ensure each step met international grain storage standards.
Commissioning and Training (1 month): Linked testing of ventilation, monitoring, and loading/unloading systems was conducted. The cooperative’s staff received hands-on training to master the operation of the intelligent system and daily maintenance skills.
The operation of the 3,000-ton paddy silo has already brought concrete benefits to the local agricultural cooperative and surrounding farmers:paddy silopaddy silopaddy silopaddy siloGrain SilosGrain Silos
Loss Reduction: With precise moisture control and intelligent alerts, the silo is expected to cut annual paddy loss by over 150 tons. Based on local paddy purchase prices, this translates to annual economic savings of approximately 360 million Vietnamese Dong (equivalent to around 108,000 RMB).
Quality Preservation: The stable storage environment keeps the annual increase in paddy fatty acid value below 2 mg KOH/100g, ensuring milled rice maintains good cooking quality and commercial appearance—strengthening competitiveness in export markets.
Supply Stability: The silo can store about one-third of the cooperative’s annual paddy output. During market price fluctuations, it allows farmers to “store grain for better prices,” helping them avoid low-price risks and stabilize income.paddy silopaddy silopaddy silopaddy silopaddy silopaddy silopaddy silopaddy silo
“In the past, we often had to sell freshly harvested wet paddy at low prices due to poor storage conditions; now with this professional silo, we can wait for reasonable prices while keeping rice quality intact,” said Mr. Nguyen Van Thai, a local farmer.Grain SilosGrain SilosGrain SilosGrain SilosGrain SilosGrain SilosGrain Silos
The successful delivery of this 3,000-ton paddy silo project marks another key achievement for LIAONING QIUSHI in Southeast Asia’s grain storage market. To date, the company has completed nearly 20 grain storage projects in Vietnam, Thailand, Malaysia and other countries, with a total storage capacity exceeding 50,000 tons.
“Vietnam, as a major global grain exporter, plays a crucial role in regional and global grain security. Enhancing its grain storage capacity is of great significance,” said the Overseas Business Director of LIAONING QIUSHI. “In the future, we will continue to develop customized storage solutions based on local agricultural characteristics, promote the implementation of intelligent and green storage technologies in Southeast Asia, and contribute ‘Chinese solutions’ to global grain loss reduction and secure supply.”
