SiroSilo Industrial
4-in-1 grain storage technology includes four aspects: grain condition monitor & control, mechanical ventilation, grain cooling, fumigation & insecticide.
- Grain Condition Monitor & Control
Modern electronic technology is now involved in the process of grain storage, helping to monitor, analyze, predict & control grain conditions in real-time.
The grain condition monitor & control system consists of monitor & control hosts and extensions.
After the monitor & control extensions collect the grain condition data, it transmits the data to the control center through wired or wireless signals, and the grain condition appears on the monitoring software interface in real-time.
The software can automatically or manually start or stop related equipment for cooling & dehumidification.
There are temperature & humidity sensors in the silo, which can detect the temperature & humidity at any time.
- Mechanical Ventilation
The key to safe wheat storage is to prevent mildew, heat & pests in the silo, the grain pile & surrounding environment’s temperature & humidity are the main influencing factors.
Intelligent mechanical ventilation has the ability to control the humidity & temperature inside the corrugated grain silo, mainly involves the following aspects:
- Special Ductwork Design
- Ventilation Timing
- Temperature & Humidity Difference
- Air Volume & Exchange Frequency Adjustment
As ductwork design also takes into account both fumigation & grain cooling, thus preventing the food damage.
- Grain Cooling
By grain cooling, the temperature of the grain is ≤15℃, which can greatly slow down the grain “breathing”, achieve the purpose of long-term preservation, and prevent the reproduction of grain insects.
When the temperature of the grain pile in the silo exceeds the standard, the grain cooler generates cold air, sends it into the silo through the ventilation system, cooling the grain.
The grain cooling technology not only reduces the grain temperature in the silo bin but also adjusts the grain moisture properly.
Grain cooling is an important grain storage & preservation technology, which effectively maintains & improves the quality of stored grains.
- Fumigation & Insecticide
Fumigation & insecticide technology is based on silo theory, aerodynamic circulation theory, and chemical control theory.
The microcomputer controls the deliquescent of aluminum phosphide tablets to produce phosphine gas.
The circulation fumigation equipment forces the airflow to circulate, which promotes the even distribution of phosphine gas in the grain pile, achieving effective insecticide.
Phosphine circulation fumigation is common in wheat storage silos in northern China, 9 hours after the fumigation, it reaches a uniform state, and the insecticidal effect is good.
In addition, filling steel silos with nitrogen is also a good choice. The nitrogen enters the grain pile, flows evenly between the pores of the grains to discharge oxygen.
So that the pests will die due to lack of oxygen.
- Precautions
- Grain moisture must not exceed the standard.
If the moisture exceeds the standard, the moisture inside the grain pile flows to the surface, and then slowly frees to the air in the gap between the grains.
Grain moisture is difficult to escape from the lifeless air, it will continue to accumulate among the grains.
When the wet state reaches the saturation point, the grain begins to condense, and the phenomenon of mildew & local temperature rise will occur, threatening the safety of grain storage.
- Be sure to ventilate well to dissipate air & moisture.
