How to Maintain Your Fermentation Tank?

 
Fermentation tanks are indispensable equipment in the biotechnological fermentation process. Their performance and longevity directly affect production efficiency and product quality. Therefore, the daily maintenance of fermentation tanks is crucial. This article provides a detailed overview of various aspects of fermentation tank maintenance to help you effectively maintain the equipment and ensure its long-term stable operation.
 
1. Keeping the Tank Clean
 
Regular cleaning of the fermentation tank is essential. Here are the steps to maintain cleanliness:
 

• Regular Cleaning: Dedicated personnel should use a neutral detergent and a semi-dry cloth to wipe the tank, pipes, and valves daily.
• Avoid Corrosion: Do not use alkaline detergents to prevent corrosion of the tank or the formation of substructures.

 
2. Preventing Overload Operation
 
To extend the lifespan of the equipment, pay attention to the following points during operation:
 

• Control Parameters: Strictly control mixing speed, motor output power, surface measurement range, and valve smoothness.
• Operational Range: All parameters should be maintained within 30% to 80% of their maximum range, and overloading is strictly prohibited.

 
3. Regular Replacement of Wearable Parts
 
Some parts of the fermentation tank require regular inspection and replacement to ensure normal operation:
 

• Seals: Regularly disassemble and clean seals, including those at the air inlet, sampling port, and electrode insertion port, and replace any damaged parts.
• Valves: Frequently used valves must be regularly inspected and replaced to ensure their proper functioning.

 
4. Protection Measures for Fermentation Tanks
 
In addition to daily maintenance, the following protective measures should be taken:
 

• Filter Maintenance: The normal operation time for fine filters is six months. If the filtration resistance is too high or the filtration effect decreases, the filter should be replaced directly rather than cleaned and reused.
• Cleaning Method: Use a soft brush to clean the fermentation tank. Do not use hard objects to scrub to avoid damaging the tank surface.
• Accessory Inspection: Inspect the tank accessories annually to ensure they are in normal use.
• Moisture Prevention: Electrical components such as the appearance and sensors of the fermentation tank should not come into direct contact with water or steam to prevent moisture damage.
• Post-Use Cleaning: When the tank is not in use, it should be cleaned immediately, and residual water in the tank and pipelines should be drained. Loosen the tank cover and spray hole screws to prevent deformation of the sealing rings.
• Rust Prevention: Carbon steel equipment such as operation paths and constant temperature tanks must be painted annually to prevent rust.
• Reducer Maintenance: Carefully observe the oil level of the reducer. If the lubricant is insufficient, add it promptly. Regularly change the lubricant to extend the reducer's service life.

 
5. Long-Term Inactivity Handling
 
When the fermentation tank needs to be inactive for an extended period, take the following steps:
 

• Empty the Tank: Completely empty the tank and drain any residual water from the tank and pipelines, ensuring it is dry before storage.
• Storage Conditions: Keep the storage environment dry and clean to prevent rust and damage to the equipment.

 
By following the above maintenance guidelines, you can effectively extend the lifespan of your fermentation tank, ensure its stable operation, and enhance production efficiency. Regular maintenance and timely inspection and replacement of parts not only prevent equipment failures but also save maintenance costs for the enterprise, ensuring smooth production.
