Kombucha Fermentation Tank
Stainless Steel Fermentation Tanks for Stable SCOBY Activity and Scalable Kombucha Production
ZPET Kombucha Fermentation Tanks are designed for producers who need stable microbial fermentation, hygienic processing conditions, and flexible capacity for both craft and commercial kombucha production. They are widely used in craft kombucha brewing operations, commercial probiotic beverage production, functional tea processing plants, low-alcohol fermented beverage lines, and R&D fermentation systems. With customizable capacities from 200L to 30,000L, acid-resistant stainless steel construction, optional open or closed tank design, and optional cooling systems, these tanks help producers maintain balanced acidity, consistent flavor, and repeatable kombucha quality.

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
The 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
Supports:
temperature tracking
pH observation
improved process supervision
PLC Monitoring and Batch Tracking
Supports:
batch record management
more consistent fermentation control
easier scaling for commercial production
stronger repeatability across multiple flavor lines
Manufacturing and Quality Control
Manufacturing and Quality Control
Each ZPET kombucha fermentation tank undergoes:
Precision welding and surface polishing
Leak testing and structural inspection
Passivation for corrosion resistance
Final quality control before shipment
This helps ensure durability, hygienic performance, and compliance with food-grade beverage production standards.
FAQs - Common Questions
1. What products can be made in a kombucha fermentation tank?
These tanks are suitable for plain kombucha, flavored kombucha, hard kombucha base, low-alcohol fermented beverages, and functional fermented teas.
