In the 1990s, due to backward in grain storage technology and equipment, deterioration, dew, fever, insect infestation and mildew occurred from time to time during grain storage, resulting in an alarming loss of grain at that time. With the development of science and technology, the four-in-one technology of grain storage is applied to steel silos.
The "four in one" grain storage technology is adopted to match the original grain processing technology, such as cleaning and screening, grading and air suction and dust removal. Through the mature and complete management method, it can greatly realize the safe storage of grain.
What is four-in-one storage technology? The FDSP will introduce to you in details.
【FDSP】8-4000T Corn silo storage project in grain industry
Jiangsu Liangyou Zhengda Co., LTD. is specialized in the research and development, design and manufacture of steel silo equipment and storage system engineering technology. The silo can be equipped with temperature measuring system, ventilation system, material level indicator and circulation fumigation system according to customer requirements. It can achieve the goal of low temperature grain storage with lower cost, greatly improve grain storage quality, prolong storage time, reduce aging, reduce pest control cost, and ensure grain storage safety.
1.Detection of grain situation
Electronic technology can be used to realize real-time monitoring, analysis, prediction and control of grain situation changes in the process of grain storage. It can also expand monitoring of grain situation, such as grain moisture, insect pests and phosphine gas concentration. Through software, the staff can grasp the food situation in a timely manner, analyze whether it is in a normal state, and take measures such as cooling or dehumidification to ensure food security.At the same time, data printing can be saved.
According to the needs and climatic conditions, ventilation should be carried out timely to reduce the temperature and moisture of grain and increase the safety of grain storage. Mechanical ventilation is a common and effective technology for grain storage. The mechanical ventilation technology of grain storage is to use the ventilation equipment to promote the gas exchange of grain in the silo, to balance grain temperature and moisture, and to prevent heating and mildew.
The phosphine circulation fumigation technology is to force the air circulation through the circulation fumigation system to make the phosphine gas evenly distributed in the steel silo, so as to achieve the effective purpose of insecticidal.
When the average grain temperature is above 25℃ and there is no resistant species, the minimum concentration of phosphate in the steel silo should be kept above 70m1/m(PPM). When the average grain temperature is below 25℃ or there are worms or resistant insect species, the minimum phosphine concentration in the grain heap should be kept above 100m1/m(PPM).
Grain cooling in steel silo is controlled by cooling to keep the temperature below 15℃(low temperature) or 20℃(quasi-low temperature) for a long time. It can keep grain fresh for a long time, avoid pest reproduction, and avoid chemical fumigation pollution, so as to realize green grain storage. Through the ventilation network into the lower layer of the grain stack, under the effect of cold negative pressure, the cold air in the movement process from bottom to top, fully absorb the heat of grain, and then the hot air is discharged out of the silo through the axial flow fan at the top of the silo.
FDSP was founded in the year of 2003, which locates in Liyang city,Jiangsu Province ,China, covering the area of 35000㎡. As a national high-tech enterprise,FDSP company will always be the first rank, which is the supplier and advanced system solution for the Feed machinery, biomass machinery, fertilizer machinery and project, etc. The main business is design, research, manufacture, sale, installation and wholesale project service for feed machinery, biomass machinery, fertilizer machinery, silo machinery, pellet mill molds and intelligent control system.
