《GB/T 29374-2022粮油储藏 谷物冷却机应用技术规程》由TC270（全国粮油标准化技术委员会）归口，TC270SC3（全国粮油标准化技术委员会粮食储藏及流通分会）执行，主管部门为国家粮食和储备局。
Introduction
1. Background and significance of standard formulation
GB/T29374-2022 "Technical Specification for Application of Grain Coolers in Grain and Oil Storage" is an important standard for the field of grain and oil storage, which aims to regulate the application of grain coolers and ensure the quality and safety of grain during storage. With the expansion of my country's grain reserves and technological advances, the old version of the standard can no longer meet the needs of modern grain storage.
2. Key analysis of standard revision
| Standard content | 2012 version requirements | 2022 version updates |
|---|---|---|
| Equipment configuration | Basic configuration requirements | Add requirements related to horizontal valley cooling ventilation, and clarify equipment performance indicators |
| Warehouse requirements | Only require insulation and airtightness | Refine the requirements for insulation, airtightness and grain condition detection systems |
| Operating conditions | Basic requirements for ambient temperature and humidity | Add technical requirements for circulating cooling and environmental adaptability analysis |
3. Key points for the implementation of the standard
Equipment selection and layout:Rationally select equipment according to the scale of grain storage and climatic conditions to ensure the scientific design of the ventilation system.
Storage requirements:Focus on checking the integrity of insulation, air tightness and transverse ventilation system.
Operation parameters:Precisely control the temperature and humidity of the air outlet to ensure the balance between cooling effect and energy efficiency.
4. Grain cooler operation specifications
Actual application case analysis: Circulation cooling technology
In the low temperature season, a grain depot uses circulation cooling technology to achieve energy saving and cooling. By recycling the air in the warehouse, it not only reduces energy consumption, but also avoids the problem of condensation in grain piles.
5. Implementation Suggestions
- Regularly train grain storage management personnel to master the operation and maintenance of grain coolers.
- Establish a complete grain condition monitoring system to monitor the grain storage environment in real time.
- Adjust the grain cooling and ventilation time according to climate change, and give priority to nighttime operations to reduce energy consumption.
