Grain Storage and Drying

As an important source of income for farmers and a raw material for many industrial products, grain quality assurance is crucial. High-quality grain can not only increase farmers' income, but also meet human needs, promote industrial production and promote economic development. Grain storage and drying are two key links to ensure grain quality. The importance and related technologies of these two aspects will be discussed in detail below.

Grain Storage Technology

Grain storage refers to preserving grain under specific environmental conditions to extend its shelf life and avoid loss and waste. For large and medium-sized industrial grains, steel silos are commonly used storage facilities.

To Ensure The Quality of Grain In Steel Silos, The Following Measures Can Be Taken:

Cleaning and Dust Removal: Clean the silo regularly to keep it dry and clean to prevent food contamination.

Temperature and Humidity Control: Use ventilation equipment to maintain good ventilation, control storage temperature and humidity, and prevent grain from mold, deterioration or moisture.

Pest Control: Take preventive measures such as regular cleaning, disinfection, sealing storage containers, etc. to prevent pest damage.

Quality Monitoring: Regularly check the quality of stored grains and deal with discovered problems in a timely manner.

Storage and Rotation In Batches: Store grains in batches and rotate them regularly to avoid quality degradation caused by long-term storage.

Identification Management: Detailed identification of stored grains, including type, age, storage time and other information, to facilitate the identification and management of different batches of grains.

Grain Drying Technology

In addition to storage, grain drying is also a key link to ensure quality. In order to accurately control temperature and humidity, not be affected by weather, and be suitable for large-scale or occasions requiring precise control, mechanical drying is usually used. The drying tower is the most suitable drying equipment for the grain silo.

Grain Drying Tower Process Flow

Preparation Stage: evenly load the grain into the drying tower.

Heating and Drying: start the equipment and provide heat source through gas, steam or electric heating.

Temperature and Humidity Adjustment: control the drying environment to ensure suitable drying conditions.

Hot Air Drying: hot air passes through the grain pile and takes away moisture.

Dehumidification Treatment: drain the moisture in the grain through the dehumidification pipe.

End of Drying: stop drying when the appropriate dryness level is reached.

Precautions When Using Drying Tower

Safe Operation: Operators must be familiar with equipment operation methods and safety regulations.

Regular Maintenance: Clean and maintain equipment to ensure proper operation and drying efficiency.

Ventilation Guarantee: Ensure good ventilation during the drying process to avoid accumulation of heat and overheating of grain.

Temperature and Humidity Control: Reasonably control temperature and humidity according to grain characteristics and drying requirements.

Regular Inspection: Monitor the drying status of grain to ensure the degree of dryness and quality.

Prevent Over-drying: Pay attention to control the degree of drying to avoid affecting grain quality and commercial value.

Operating Skills: Ensure operators have the necessary skills and experience.

Storage and drying have a significant impact on grain quality. Improper storage may cause grains to become damp, moldy, or infested by insects, while proper drying can effectively reduce moisture content, prevent mildew and rot, extend storage time, and improve overall quality. Therefore, the use of scientific storage and drying methods is crucial to maintaining the quality and nutritional value of grain, and is also an important measure to ensure national grain security.
