Core Production Equipment
1. Straw Bale Breaking & Coarse Shredding System
Function: Breaks straw bales, shreds to 50-100mm fragments, removes soil/metallic impurities.
Key Equipment:
Heavy-duty Chain Conveyor: Capacity 20 tons/hr, wear-resistant design;
Dual-Shaft Shredder: Power 160kW, Hardox 500 blades (HRC 58-62), anti-wrapping structure;
Magnetic Separator: Magnetic field ≥12,000 Gauss.
Straw Specificity: Enhanced impurity removal (soil content 8-15%, higher than wood).
2. Fine Grinding & Fiber Activation Unit
Function: Refines particles to target size (20-50mm length, 0.2-0.5mm thickness), steam-softens wax layer.
Key Equipment:
Hammer Mill: Speed 2,800 rpm, Φ8mm screen (custom anti-clog design);
Steam Pre-treatment Vessel: Pressure 0.6MPa, temp. 160°C, residence time 3-5 min (disrupts silica layer for better bonding).
Capacity: ≥12 tons/hr (dry basis) for continuous feeding.
3. Rotary Drying System
Function: Reduces moisture content from 35-50% to ≤8%.
Core Equipment:
Triple-Pass Rotary Dryer: Φ3.2m diameter × 24m length, hot air 180-220°C;
Biomass Hot Air Furnace: Fueled by straw fines, thermal efficiency ≥85%;
Cyclone + Wet ESP: Dust emission ≤20mg/m³ (EU standard).
Energy Saving: Exhaust heat recovery reduces energy use by 40% vs. wood drying.
4. MDI Blending & Forming System
Function: Precise MDI resin application (4-5%), forms uniform mat.
Key Equipment:
High-Pressure Resin Blender: Resin droplet size ≤50μm, application error ±0.3%;
Air-Flow Forming Machine: Speed 80m/min, density deviation ≤±3% (laser monitoring);
Wax Dispensing Unit: Wax melting temp. 90°C, dosage 0.8-1.2% (waterproofing).
Straw Adaptation: Optimized spray angles overcome hydrophobic surface.

5. Continuous Press
Function: Cures mat under heat/pressure into stable boards.
Core Equipment:
Continuous Press:
Width 2.7m, length 30m;
Pressure gradient control (3.0→0.5MPa);
Temp. 200±5°C, thickness range 8-40mm;
Line speed 800mm/s (18mm board).
Advantage: Hydraulic servo closed-loop control optimizes density gradient.
6. Finishing Line
Function: Cooling, trimming, and surface finishing.
Equipment | Parameters & Function |
Roller Cooler | Cooling time ≥25 min (stress relief) |
Double-End Trimmer | Cutting accuracy ±0.5mm, power 55kW×2 |
4-Head Calibrating Sander | Sanding depth 0.1-1.5mm, grit sequence P60→P120→P180→P240 |
Automated Stacking Robot | Stack height 1.8m, positioning accuracy ±1mm |

7. Emission Control System
Function: Treats dust/VOCs from production.
Key Units:
Central Dust Collector: Airflow 120,000m³/h, filtration precision 0.1μm (PTFE membrane);
RTO (Regenerative Thermal Oxidizer): VOCs removal ≥99%, gas consumption ≤80m³/h;
Wet Scrubber: Treats press exhaust with pH auto-adjustment.
Global Straw Sources & Advantages
Key Regions: China (Hubei/Jiangsu/Heilongjiang: 200-220M tons), USA (200-250M tons), EU (Belgium/Germany: ~4M tons)；
Supply Advantages: Rice straw costs 30% less than wood; ≤50km collection radius controls logistics; low ash (5.2%) enhances glue bonding.
Eco-Performance: Zero formaldehyde (MDI technology), CARB/EPA certified；
Physical Strength: MOR ≥14MPa, IB ≥0.45N/mm², density customizable (0.4-0.8g/cm³)；
Functionality: Water absorption ≤12% (24h immersion), sound absorption coefficient 0.6 (30% better than wood)；
Workability: Optimized pre-drilling parameters for dowel joints reduce edge chipping.
Furniture: Cabinet bodies, tabletops (formaldehyde-free safety)；
Construction: Acoustic wall panels/ceilings (0.4-0.6g/cm³ grades)；
Packaging: Machinery pallets (water-resistant)；
Interior Decor: Floor underlay, door cores (cost-effective MDF alternative).
