Correct and Safe Use of Stainless Steel Fermentation Tanks
On this page
In industries like food processing, chemical engineering, and biopharmaceuticals, stainless steel fermentation tanks are commonly used for fermenting various microorganisms. But if you don't use them right, their lifespan might get shorter. So, below, we'll go over the steps for using stainless steel fermentation tanks and some important things to remember. This should help you use them better and make them last longer.
Operational Steps
Before you start fermenting anything, it's crucial to get the steps right. Here's a simple guide on how to use stainless steel fermentation tanks, from getting things ready to keeping an eye on the fermentation process.
- Calibrating the Probes: Before you start fermenting, make sure to calibrate the probes that measure dissolved oxygen and pH levels. This is super important because these factors affect how well the microorganisms grow and ferment.
- Sterilizing the Tank: After you've put the culture medium into the tank and sealed it up, it's time to sterilize it in a big sterilization machine. This makes sure there are no harmful germs inside. Make sure the sterilization temperature and time are right to kill off any bad germs.
- Preparation for Fermentation: Once the tank has cooled down, set it up on the fermentation stand and get everything connected. Turn on the cooling water and air pump, and adjust the air intake to get the right airflow. Then, power up the tank, set the temperature, pH, and stirring speed, and let it warm up. It's important to get these settings right for the microorganisms to grow well.
- Adding the Starter and Monitoring: After the tank has stabilized, add the pre-shaken starter culture and start the timer. Keep an eye on the temperature, pH, and other factors and write down any changes you see. Using good-quality starter culture is really important for successful fermentation.
- Fermentation Process Monitoring: Throughout the fermentation, regularly check the temperature, pH, and dissolved oxygen levels. If anything seems off, adjust it to keep things on track. This helps make sure the fermentation goes smoothly.
- Conclusion of Fermentation: Once the fermentation is done, clean the tank and probes thoroughly. Store the probes in a solution of potassium chloride. Don't forget to fill out any necessary paperwork and get it signed by the person in charge.
Major Considerations
Besides following the steps, there are a few other things to keep in mind to make sure everything goes smoothly.
1. Check the Liquid Level: Before sterilizing the tank, make sure the liquid level is right so that all the probes are submerged. This helps avoid contamination. Also, make sure you've prepared the culture medium correctly.
2. Double-Check the Power: Before turning on the tank, make sure the cooling water and temperature probes are ready. This prevents any damage to the tank. Also, check that all the power connections are correct to avoid any problems.
3. Keep Your Workspace Clean: During fermentation, keep your workspace tidy. Clean up any used bottles or spills to prevent contamination. A clean workspace reduces the risk of germs getting into your ferment.
4. Handle with Care: When installing, disassembling, or sterilizing the tank, be careful, especially with delicate parts like pH probes. Also, make sure everyone knows what they're doing and follows the rules.

By following these steps and keeping these tips in mind, you can make the most out of your stainless steel fermentation tanks. This will help them last longer and ensure your production process runs smoothly. These guidelines cover everything from getting the equipment ready to monitoring the fermentation process, making it easy for anyone to use these tanks effectively.
