The 2026 Edible Fungi Whole Industry Chain (Xiamen) Innovation Expo is scheduled to take place grandly at the Xiamen Baixiang Expo Center from September 20 to 22, 2026. Themed "Consolidating Foundations · Connecting · Leading," the expo features "Three Core Value Clusters" exhibition areas designed to establish an industry value community that connects upstream and downstream resources.

Foshan Shunde Dongxing Decoration Engineering Co., Ltd. (Booth No.: A229) will make a major appearance at this expo. As an aluminum alloy valve manufacturer specializing in airtight volume dampers, Dongxing presents its Bilianchu Dedicated Fresh & Return Air Control Dampers for Mushroom Cabins. Delivering military-grade sealing and smart precision airflow control, Dongxing offers an efficient, energy-saving, and stable air management solution for mushroom cabin cultivation systems.

1. Precise Requirements Across Growth Stages:

Whether during the mycelium phase or fruiting phase, CO₂ concentration requires precise control that standard dampers cannot dynamically adjust. Meanwhile, excessive humidity breeds unwanted bacteria, while insufficient moisture inhibits mushroom development; the fresh-to-return air ratio directly dictates humidity balance in the cabin.

2. Common Defects of Traditional Ventilation Equipment:

• Poor Sealing: Air leakage causes severe energy waste and large fluctuations in temperature and humidity.

• Weak Corrosion Resistance: High humidity in mushroom cultivation causes standard steel equipment to rust quickly, shortening service life.

• Coarse Adjustment: Manual dampers rely heavily on experience and cannot integrate with automated smart cabin systems.

1. Fresh Air Control Damper —— Smart Ventilation for Pure Airflow

• Military-Grade Sealing: High-strength aluminum alloy valve body paired with EPDM or food-grade silicone seals ensures ultra-low leakage, surpassing national airtight volume damper standards.

• Efficient Filtration: Equipped with nylon filter meshes on fresh and return air dampers to prevent outdoor contaminants from entering.

• Precision Airflow Regulation: Multi-stage electric blade structure (optional pneumatic actuator) supports 0-100% stepless adjustment, responding real-time to PLC systems and CO₂ sensor data.

• Long-Lasting Corrosion Resistance: Anodized surface finish resists acid, alkali, and mold, thriving in high-humidity environments with a service life over 10 years.

2. Return Air Control Damper —— Energy Circulation & Cost Reduction

• 3-in-1 Efficient Air Mixing: Unique blade structure evenly blends fresh and return air to eliminate dead zones and ensure uniform temperature/humidity distribution.

• Heat Recovery Compatibility: Interfaces adapt to heat exchangers to recover residual heat and moisture, cutting total HVAC energy consumption by over 30%.

• Low-Noise Operation: Streamlined blade design minimizes noise, preventing sound wave vibration interference with mycelium growth.

• Enoki / King Oyster Mushroom: Low CO₂ environment required; fresh air dampers open widely with return air assisting circulation to promote stalk elongation.

• Shiitake / Oyster Mushroom: Phased adjustment; fresh air is reduced during the mycelium phase and increased during fruiting along with humidity control.

• Rare Varieties (e.g., Morel): High-precision closed-loop control with dampers linked to environmental sensors to simulate natural growth climates.
