Key Advantages of Kombucha Fermentation Tanks
Stable SCOBY Fermentation
The tank design supports healthy SCOBY growth and balanced microbial activity, helping producers maintain more stable fermentation performance.
Flavor Consistency
Controlled fermentation conditions help prevent excessive acidity, flavor imbalance, and unwanted fermentation variation from batch to batch.
Food Safety and Hygiene
Stainless steel construction and CIP compatibility help meet food and beverage hygiene standards while reducing contamination risk.
Scalable Production
Available from 200L to 30,000L, these tanks are suitable for both small craft fermentation and high-volume commercial kombucha production.
Flexible Product Development
The system supports plain kombucha, flavored kombucha, hard kombucha base, and functional fermented tea, allowing producers to diversify their product portfolio.
Kombucha Fermentation Process Overview
This process helps producers achieve balanced acidity, probiotic stability, and repeatable beverage quality.
1. Sweet Tea Filling
Prepared tea and sugar solution are transferred into the fermentation tank.
2. SCOBY Introduction
SCOBY and starter liquid are added to begin fermentation.
3. Primary Fermentation
Controlled fermentation takes place under aerobic or semi-controlled conditions depending on the production method.
4. Monitoring
Key variables such as pH, temperature, and time are monitored to guide fermentation stability and flavor balance.
5. Secondary Fermentation
Key variables such as pH, temperature, and time are monitored to guide fermentation stability and flavor balance.
6. Transfer and Packaging
The finished kombucha is transferred for bottling, canning, or further conditioning.
Optional Automation and Smart Monitoring
Les Kombucha Fermentation Tank can be configured with different levels of monitoring and control depending on production scale and standardization goals.
Basic Manual Monitoring
Suitable for smaller craft kombucha operations and pilot production.
Digital Monitoring
Prend en charge :
temperature tracking
pH observation
improved process supervision
PLC Monitoring and Batch Tracking
Prend en charge :
batch record management
more consistent fermentation control
