BIOMASS STEAM EXPLOSION
IR-SE5 / IR-SEC20Batch and continuous steam explosion reactors that convert straw, bagasse and wood fibre into pulp, feed and bio-based feedstock using pure saturated steam — no chemicals.
FIBRE
RUPTURED BY
STEAM ALONE.
IREGE steam explosion systems thermo-mechanically treat lignocellulosic biomass with high-pressure saturated steam, then release it in a flash decompression that tears apart the fibre structure.
Biomass is charged into the reactor, pressurised with steam at 1.5–3.5 MPa and held at 180–230 °C for a controlled retention time. A rapid discharge valve drops the pressure in milliseconds, exploding the cell walls and separating cellulose, hemicellulose and lignin without any chemical additives.
The result is a highly digestible, sterilised fibre — ready for pulp, animal feed, bioethanol pretreatment or biocomposite feedstock. The line is available as a 5 m³ batch reactor or a 20 t/h continuous system, both operated from a single PLC + SCADA control room.
ENGINEERED DOWN TO THE FASTENER.
BUILT FOR CONTINUOUS DUTY.
Certified Pressure Vessel
Reactor designed and stamped to ASME / GB 150 standards for safe high-pressure cyclic duty.
Rapid Decompression Valve
Sub-second flash discharge ruptures fiber structure for consistent explosion treatment.
Steam Accumulator Buffer
3.5 MPa accumulator stabilizes pressure during batch charging for uniform cook results.
Precise Thermal Control
Closed-loop steam regulation holds temperature within ±2 °C across the full retention window.
Heat Recovery Loop
Flash steam is captured and returned to the boiler feed, cutting net energy use per tonne.
PLC + SCADA Automation
Recipe-driven recipes for straw, bagasse and wood fibre with full production data logging.
Modular Fiber Separation
Cyclone and refiner modules separate treated fibre from condensate and volatiles.
Solvent-Free Process
Pure steam treatment — no chemical additives, compatible with food and feed output streams.
WHERE IT WORKS.
- Non-wood pulp & paper (straw, bagasse)
- Animal feed — improved straw digestibility
- Bioethanol feedstock pretreatment
- Biocomposites & bio-based materials
