Intelligent counter-flow grain drying system with heat recovery

Main advantages

  1. Counterflow drying technology
    The drying, tempering, and cooling processes mimic natural drying, fully preserving the grain's structure and nutritional properties.
  2. Temperature mode adjustment
    Three modes are available: high, medium, and low. Suitable for any crop, ensuring high-quality drying and significant energy savings.
  3. Uniform drying
    Optimized airflow distribution eliminates moisture variations, ensuring all grain is dried to the same degree.
  4. Energy-saving design
    A double-layer housing with heat recovery reduces energy consumption. The equipment is aesthetically pleasing, airtight, and environmentally friendly.
  5. Full intelligent automation
    Equipped with online control, automatic temperature adjustment, video surveillance, and fault alarm system. Start and stop control is operated with one button.


Product Details

Detailed product description

This intelligent system is designed for comprehensive drying and cleaning of agricultural crops. Thanks to modern automated control systems, optimal operating parameters are maintained, moisture is removed evenly, while all beneficial properties of the grain are preserved. The equipment operates stably even when processing large batches of crops, ensuring high quality and safety of the final product.

The complex includes a drying tower, a heating unit, circulation fans, and an intelligent control unit. Grain enters the tower, where a hot air flow evenly processes the entire mass, removing moisture from both the surface and the interior of the grains. The control system monitors and adjusts temperature, humidity, and air speed in real time, maintaining a stable technological process.

The equipment is versatile in application: it is suitable for drying grains, legumes, oilseeds, and other agricultural crops. Its use allows enterprises to improve the quality of food grains, reduce storage losses, and supply consistently high-quality products to the market.
