Industrial Mushroom Substrate Mixer (Batching Tank)
The Industrial Edible Mushroom Substrate Mixer (Batching Tank) is designed for secondary batching and moisture/nutrient homogenization in mushroom substrate preparation. It blends pre-wetted substrate raw materials (pre-treated sawdust, cottonseed hulls, corncob, wheat bran) with water, gypsum, and nutrient supplements. Driven by heavy-duty twin counter-flow ribbon augers, it features timed water dosing manifolds and a reinforced discharge gate. Available in 4m³, 5m³, 6m³, 8m³, and 12m³ custom capacities, it delivers rapid 5-8 minute mixing cycles with 100% moisture consistency.

Available Configurations
Available ConfigurationsStandard Operating Procedures (SOP)
1. Substrate Pre-treatment & Loading: Load pre-wetted substrate raw materials (sawdust, cottonseed hulls) and additives into the tank.
2. Mixing & Dosing Cycle: Start main drive motor and water pump; twin augers rotate for 5-8 minutes to homogenize moisture.
3. Gate Opening & Discharge: Upon completion, open bottom discharge gate to feed mixed substrate onto conveyors or elevators.
4. Cleanup & Maintenance: Disconnect main power after operation, clean internal residues, and inspect belt/chain tension and oil level.
Safety Precautions & Maintenance
Mechanical Safety: Never reach hands, arms, or tools inside the mixing chamber or discharge port while augers are rotating.
Drive & Gearbox Maintenance: Replace gear oil after initial 100 hours of operation, then every 1,000 hours; grease chains & bearings regularly.
Overload Prevention: Strictly prohibit overloading or inserting hard foreign objects (e.g. stones, iron blocks) to prevent blade damage.
Electrical Safety: Ensure RCD protection and grounding. Lock out main power before internal cleaning; do not spray water on control panels.
Frequently Asked Questions
What agronomic advantages do twin-shaft ribbon mixers have over single-shaft mixers?▾
Twin counter-flow ribbons force light and heavy raw materials (sawdust, corncob, wheat bran, gypsum) into 3D cross-convection, completely eliminating dead zones and uneven micro-nutrient distribution.
What is the batch mixing capacity and cycle time?▾
Available batch sizes include 400kg, 800kg, 1,200kg, and 2,000kg. A complete batch from feeding and water dosing to discharge takes only 4 to 6 minutes.
How does the discharge gate prevent water leakage?▾
The bottom features a pneumatic/manual full-open discharge gate with heavy-duty rubber seals, preventing liquid seepage and enabling 15-second rapid discharge into auger conveyors.
