Phase-2 Pasteurization Tunnels for Mushroom Farms
PUF-insulated pasteurization tunnels with steam boiler, plenum airflow, and digital controllers. Precision 58-62°C pasteurization for contamination-free Agaricus bisporus compost. From ₹8 lakhs for single tunnel.
What Is a Phase-2 Pasteurization Tunnel?
A Phase-2 pasteurization tunnel is an insulated chamber equipped with steam injection and air handling systems that heat mushroom compost to 58-62°C for 6-8 hours (killing pathogens and competitor molds), then condition it at 48-52°C for 5-7 days to promote beneficial thermophilic microorganisms. This produces clean, selective substrate ready for spawning.
Why Pasteurization Is Non-Negotiable
ICAR-DMR research confirms that unpasteurized compost leads to 50-80% crop failure from Trichoderma green mold, nematodes, and competitor fungi. A proper Phase-2 tunnel ensures selective compost with 10× lower contamination risk compared to room pasteurization.
What's Inside a MushroomWale Phase-2 Tunnel
PUF Insulated Walls
80-100mm PPGL PUF panels for thermal efficiency. Maintains 58-62°C with minimal steam loss.
Plenum Air System
Under-floor grated plenum ensures uniform airflow through the compost mass for even pasteurization.
Steam Boiler System
500-1000 kg/hr boiler with precise steam injection for rapid temperature ramp-up.
Complete compost infrastructureDigital Controls
Multi-zone temperature monitoring with 6-8 probes. Optional PLC automation for hands-free operation.
Recirculation AHU
Air handling unit with dampers for precise fresh air:recirculation ratio control during conditioning.
Commissioning & Training
Complete testing, first-batch supervision, and operator training on pasteurization protocols.
