① Core Concept
A continuous press is essential for manufacturing wood-based panels (e.g., particleboard, MDF). It applies heat and pressure continuously via moving steel belts, replacing batch presses for higher efficiency.
② Working Principle
Process Flow:
Mat forming → Pre-pressing → Continuously enter the hot pressing section → Multi - stage heating plate pressurization→Temperature/pressure segmented control → Cooling → Cutting
Key Action: Simultaneous movement and curing of panels under controlled conditions.

③ Main Components
Component | Function |
Heating Plates | Heat transfer via thermal oil/steam |
Hydraulic Cylinders | Zone-specific pressure (up to 5000 tons) |
Steel Belt | Continuous panel conveyance (1-2 m/min) |
RTD Sensors | Real-time temperature monitoring |
④ Advantages
30% higher output vs. batch presses
Energy savings up to 40%
Superior surface flatness (±0.15 mm)
① Heat Recovery
Exhaust heat → Pre-drying raw material
Cooling water heat → Factory heating
② Zoned Control
Independent temperature/pressure for 20+ zones
Variable-frequency drives reduce idle power
③ Insulation
Ceramic fiber layers (thermal conductivity <0.1 W/m·K)
Reflective stainless steel shields
① Control Logic
Sensing: RTD sensors (±0.3°C accuracy) feed data to PLC
Adjustment: PID algorithms modulate thermal oil valves (±0.5% flow)
Cooling Assist: High-speed water valves intervene within 1 second
② Critical Components
Thermocouple Grid: 8-12 sensors per plate
Proportional Valves: Oil flow precision ±0.8%
IR Thermal Camera: Monitors surface uniformity
③ Implementation
Predictive pre-heating based on material moisture
Dynamic compensation for belt speed changes
Dual-loop control:
Inner loop: Oil temperature (±0.5℃)
Outer loop: Plate surface temperature (±1℃)
(1) Energy Consumption vs. Batch Presses
Parameter | Continuous Press | Batch Multi-Opening Press | Energy Saving |
Steam per ton of board | 0.8-1.2 tons | 1.5-2.2 tons | ≥35% |
Electricity consumption | 18-25 kWh/m³ | 30-40 kWh/m³ | 30-40% |
Thermal efficiency | 75-85% | 45-55% | 0.3 |
Idle loss ratio | <5% | 15-20% | 3× reduction |
(2) Core Energy-Saving Technologies
① Heat Recovery System (60% of total savings)
Cascaded waste heat utilization
Exhaust gas 180-220℃ --> Pre-heat drying kiln
Cooling water 60-80℃ --> Factory heating
Thermal oil return 240℃ --> Raw material pre-heating
Waste heat recovery rate: ≥85% (vs. <40% in conventional systems)
Steam reduction: 120 kg/m³ board (validated case)
② Dynamic Zoning Control (25% of savings)
20-30 independent thermal zones:
Precise temperature profiling (e.g., 200°C inlet → 160°C outlet)
Eliminates parasitic heat loss from overheating
Variable-frequency hydraulic control:
Pressure adjustment based on board position (high inlet → low outlet)
Motor power reduction: 40% (vs. fixed-frequency systems)
③ Advanced Insulation (15% of savings)
Component | Material | Heat Loss Reduction |
Press plate exterior | Nano-aerogel mat (5cm thick) | 0.55 |
Steel belt joints | Ceramic fiber seals | 0.7 |
Thermal oil pipelines | Vacuum-insulated jackets | 0.9 |
(3) Secondary Benefits from Energy Efficiency
① Quality improvement reduces waste:
Enhanced temperature uniformity → +15% internal bond strength
Reject rate drop from 4.2% to 1.5% (equivalent to 3% energy saving)
② Extended equipment lifespan:
Reduced thermal stress → Plate service life extended from 3 to 8 years
Lower hydraulic wear → Maintenance costs down 25%
③ Smart energy management:
Real-time zone-wise monitoring (±2% accuracy)
AI-generated optimization (e.g., lowering edge-zone temperature during night shifts)
(4) Key Energy-Saving Mechanisms
① Heat Recovery Cascade
Recycles 85% waste heat from exhaust/cooling systems
Pre-dries raw materials using 180°C exhaust gas (15% steam reduction)
② Adaptive Zoning Technology
30+ thermal zones with dynamic temperature/pressure profiling
Variable-frequency drives cut motor energy by 40%
③ High-Performance Insulation
Component | Material | Performance |
Press plates | Aerogel insulation | 55% heat loss reduction |
Belt joints | Ceramic fiber seals | 70% leakage prevention |
④ Operational Impact
39% lower energy per m³ versus batch presses
$470,000 USD/year savings in steam costs (validated case)
38% CO₂ reduction supporting carbon neutrality
