Mechanical Aeration Principles of Steel Grain Storage Silo System

I. Avoid to reduce grain moisture content:
- Choose min air flow with the basis of meet aeration requirements.
- As min as possible atmosphere temperature and as high as possible humidity.
- Reasonable aeration equipment configuration.
- Judge the right time for mechanical aeration.
II. Prevent and handle moisture condensation of grain bulk:
- Judge the right aeration condition
- The temperature difference between inside and outside grain bulk should be smaller than the temperature difference of moisture condensation.
- After aeration, ensure the temperature difference between grain bulk and inside silo temperature is smaller than moisture condensation.
- When moisture condensation happens, take measure immediately according to bad grain degree.
- When light moisture condensation happens, by nature aeration and continuous aeration to exhaust hot and humidity air.
III. Prevent and handle aeration dead corner:
- When design aeration networks, with the basis of meeting aeration requirements, choose small air path ratio system, and equip reasonable equipment.
- Use single pipe to handle aeration dead corner.
