    Security protection On Grain Storage by 4 in 1 Technology Hasen Tech Forum

     

     

     

     In-depth analysis of the application value

     

    Four-in-One technology in the Grain Industry 

     


                                             

                                                          ---Contribution by WUXI HASEN IMPORT AND EXPORT CO.,LTD

     
    Beginning in the 1990s, in order to enhance the national macro-control capacity of grain,

     

    the State Council of China decided to establish a national special grain reserve system,

     

    due to the lack of storage capacity, technology and equipment backward, poor quality

     

    during grain storage, dew, heat, pests, mold sometimes occur, the alarming

     

    loss, in order to solve this problem and the introduction of grain storage "four-in-one"

     

    technology.


     

    Four-in-one storage principles and processes:

     

    This discussion is based on intelligent ventilation, circulation fumigation, intelligent grain condition

     

    detection,high-efficiency grain cooling "four-in-one" technology in the mature application of steel

     

    silos, which can be applied to the steel silo type granary and upgrade innovation.

    Grain storage process flow chart

     

    After the wet grain is cleaned and removed from the iron, it is fed into the mixed-flow dryer by

     

    the hoist and baked to the safe moisture (rice 12-14%) and then fed into the steel silo storage.

     

    During the storage period, the management personnel use the application of intelligent grain

     

    monitoring and control analysis system, circulation fumigation, combined with intelligent

     

    ventilation, high-efficiency grain cooling and other technologies, so that the steel silo can

     

    adapt to the medium- and long-term storage of grain.

    2, KEY POINT OF FOUR IN ONE ELABORATED:

     

    The safety and reliability of the equipment are improved by the use of parametric design

     

    and finite element analysis techniques in the grain plate silos of 10,000 tons.

    1, Solved circulation fumigation pest control technology

     

     

    Circulation fumigation system is based on grain silo theory, aerodynamic circulation

    theory, chemical control theory, the use of micro-computer control technology, the

    use of phosphated aluminum tablet symtolic to produce hydrogen phosphate gas,

    through circulation fumigation equipment, forced air flow circulation, to promote

    the homogenization of hydrogen phosphate gas in the grain pile, to achieve effective

    insecticidal purposes. 

     

     

     

     

    2, Smart ventilation technology

     

    The safe storage of grain is mainly to prevent mold, heat and pests in grain piles, the

     

    key factors affecting the grain pile and storage environment temperature and

     

    humidity. We use intelligent mechanical ventilation, through the special design

     

    of the wind duct, ventilation timing, temperature and humidity difference, air

     

    volume and exchange times adjustment, while taking into account ventilation,

     

    fumigation and grain cooling technology wind network design, the environment

     

    in the warehouse temperature control, control of humidity, to prevent the occurrence

     

    of food damage.

     

     

     

    3, Cooling low-temperature grain storage technology

     

    Low temperature grain storage is a temperature control storage technology to improve

     

    grain stability by means of natural methods or mechanical refrigeration methods to

     

    control the temperature, so that grain is in a low temperature state below 15 degrees

     

    C or a quasi-low temperature state below 20 degrees C. HASEN has successfully

     

    developed a mobile grain cooler that, when the temperature of the grain stack

     

    in the warehouse exceeds the standard, the cold wind generated by the grain

     

    cooler is fed into the warehouse through the air supply system to achieve

     

    the effect of cooling the grain temperature.

    4, Food situation measurement and control analysis technology

     

     

    Using modern electronic technology to realize real-time monitoring, analysis,

     

    prediction and control of food changes in the grain storage process, the system

     

    is formed by the measurement and control host and measurement and control

     

    extension network, installed in each grain silo after the control and control

     

    extension data collection of grain data to the control center by wired or

     

    wireless way, management personnel through the upper computer

     

    software timely grasp the food security situation, through the software

     

    automatic or manual control of related equipment to achieve cooling,

     

    dehumidification purposes.

     

     

     

     

     

     

    5, Food situation measurement and control analysis system

     

     

    "Four-in-one" storage technology adapts to the needs of large-scale and intensive

     

    development of China's reserve grain bank construction, and has a wide application

     

    coverage, which makes the level of grain storage technology in China go to a new

     

    level. In the application of steel plate storage grain, we must understand the

     

    structural characteristics of the steel silo, grasp the four key points of grain storage,

     

    to ensure the safety of grain storage.
