The farm implemented a "tiered purification strategy":
Skid gatekeeper (10m³/h): Skid-mounted precision filtration systems are installed at the central fuel depot intake port and circulation loop. High-flow purification begins immediately during unloading, ensuring "unpurified oil does not enter the tank."
Polymer Rigid Composite Membrane: Using Jingyuan® polymer rigid composite membrane, leveraging the oleophilic-hydrophobic properties of the membrane material, it efficiently intercepts particulate impurities while synergistically removing trace free water, ensuring in-depot fuel is clear, transparent, and meets cleanliness standards.
Periodic storage tank circulation: Periodic 10m³/h high-flow circulation purification of static stored fuel in the depot, keeping the fuel in a good state at all times.
Mobile terminal assurance (JY-219A): JY-219A units are configured on sub-farm fueling vehicles, serving as the final checkpoint before fuel enters combine harvesters.
