This production line centers on the philosophy of "resource recycling," addressing traditional technical challenges such as short fiber length, high sugar content, and significant silica content in agricultural residues through technological innovation, enabling large-scale, high-value utilization of agricultural residues in board manufacturing.
Stage 1: Raw Material Reception & Pretreatment (Most Differentiated)
Goal: Transform loose, impurity-laden agricultural residues into qualified, uniform "industrial feedstock."
1. Depacking/Unbaling & Coarse Reduction: Automatic bale breakers, straw cutters, primary shredders.
2. High-Efficiency Cleaning & Washing System: Multi-stage screens, density separators, intensive air classifiers, washing drums or dry cleaners. A critical step for removing soil, stones, metals, leaves, and grain residues. Bagasse requires specific depithing.
3. Specialized Drying Equipment: Rotary drum or belt dryers to reduce the typically high and variable initial moisture content to a stable level (approx. 15-25%).

Stage 2: Fiber Preparation (Core Section, Requires Wear Resistance)
Goal: Separate cleaned feedstock into up to standard fibers.
1. Storage & Metering: Non-bridging bins, precision belt weighers.
2. Wear-Resistant Refining System: Reinforced Defibrator/Refiner. The absolute core. Features include:
Special Alloy Wear Plates: For extreme abrasion resistance against silica.
Optimized Digestion: Adjusted parameters for non-wood fiber softening.
Optional Pre-impregnation: Chemical pretreatment to aid in breaking down pectins and sugars.
Stage 3: Resin Blending & Drying (Key: Adhesive Formulation & Mixing)
Goal: Ensure perfect bonding between fibers and specialized adhesive.
1. Specialized Blending System: High-speed ring or disc blenders with precision pumps for modified adhesives (e.g., MDI or modified UF resin).
2. Anti-Stick Drying System: Pipeline dryer with anti-adhesion design to handle the sticky nature of sugar-containing fibers.

Stage 4: Mat Forming & Hot Pressing (Adapted for Short Fibers)
Goal: Form the resinated fibers into boards.
1. Adaptive Forming & Pre-Press: Mechanical formers and belt pre-presses adjusted for shorter fiber flowability.
2. Multi-Opening Press or Continuous Press: Multi-opening presses are often preferred for greater process flexibility. Press plates may have non-stick coatings.

Stage 5: Finishing
Goal: Final processing of boards.
1. Cooling, Trimming & Sanding: Standard coolers, saws, and sanders.
2. Conditioning Chamber (Optional but Important): Climate-controlled storage for stress relief and moisture equilibration.
3. Inspection & Packaging: Automated grading, stacking, and wrapping.
Core Philosophy: An agri-residue MDF line is not a simple adaptation of a wood line; it is a dedicated system with targeted design and material reinforcements from pretreatment onwards, which constitutes its technical barrier and investment focus.
