Guidelines for the Construction of Modern Grain Warehouses in Wuxi, Jiangsu Province

According to the national "Key Technical Points for High-Standard Grain Warehouse Construction (Trial)", "Wuxi Municipal 14th Five-Year Plan for Grain and Strategic Reserves Development" and Jiangsu Provincial Food and Strategic Reserves Administration's "Modern Grain Warehouse Construction and Management Guidelines", and following the principle of"being technology-based, innovation-driven, demonstrative and application-oriented”, the Wuxi Municipal Food and Strategic Reserves Bureau compiled and released the "Guidelines for the Construction of Modern Grain Warehouses in Wuxi", which covers eight major aspects:

1. Modern warehouse types: Bulk grain bungalow warehouse (bungalow warehouse with naturally ventilated roof) and double-deck shallow round warehouse are listed as modern warehouse types that are prioritised in Wuxi.

A total of five new bulk grain bungalow warehouses will be built, with a storage capacity of 62,000 tons. When construction is completed, the five new warehouses and the existing 11 bungalow warehouses built in the first phase will form a cluster of bungalow warehouses with a total storage capacity of 148,000 tons. These bulk grain bungalow warehouses are China’s most advanced double-deck bungalow warehouses equipped with technologies of naturally ventilated roof, cross ventilation and nitrogen-filled low-oxygen grain preservation. Among them, the double-deck naturally ventilated roof uses the height difference caused by the roof slope and the setting of shutters to create a differencein air pressure and heat pressure in the insulation layer and produce a chimney-like effect, by which accumulated heat is discharged rather than transmitted down to the grain pile, a heat insulation effectis achieved, energy consumption of ventilationis reduced, and grain is well preserved.

2. Green storage of grain: Promote the application of ventilation, controlled atmosphere (nitrogen) storage, low-temperature biological pest control, active temperature control and other grain storage technologies to achieve high-quality grain storage

3. Grain loss reduction: Increase the application of technologies such as integrated grain transportation, grain drying system, and in-warehouse grain management to reduce grain waste and losses
