open top kombucha fermentation tank

Product Overview

Open top kombucha fermentation tank is the classic and mainstream equipment for commercial kombucha primary fermentation. It abandons fully enclosed structures and adopts a safe open-top breathable design, which fully adapts to the aerobic fermentation principle of kombucha.

Sufficient surface oxygen exchange ensures vigorous reproduction of beneficial bacteria and yeast, effectively improving fermentation efficiency and forming high-quality SCOBY. Equipped with dust-proof and insect-proof breathable covers as standard, it avoids contamination while ensuring air circulation, solving the core demand of traditional open brewing for sanitation and oxygen supply.

Suitable for mass primary fermentation of kombucha base tea, SCOBY expansion cultivation and daily batch brewing. It supports manual fine-tuning in the fermentation process and is compatible with all conventional kombucha brewing processes.

Core Features & Advantages

1. Professional Aerobic Fermentation Design

Full open top maximizes liquid surface oxygen contact, creates the optimal growth environment for kombucha symbiotic bacteria, accelerates fermentation, and produces thick, complete and active SCOBY, avoiding incomplete fermentation and weak bacterial activity caused by insufficient oxygen.

2. Safe Sanitary Protection System

Comes with customized high-density dust-proof cover, which isolates flies, dust and airborne miscellaneous bacteria. It keeps the tank ventilated and hygienic, greatly reducing mold contamination rate, suitable for long-term commercial batch production.

3. Premium Food-grade Stainless Steel Material

Adopts SUS304 standard / SUS316L optional stainless steel, inner wall mirror polished (Ra≤0.4μm), smooth and residue-free, acid and corrosion resistant, no chemical precipitation, fully compliant with FDA and CE food safety standards.

4. Easy Operation & Low Maintenance Cost

Wide open top design allows convenient SCOBY picking, tea liquid sampling, residue cleaning and tank inspection. No complex pressure control system, simple structure, stable operation and low failure rate, reducing daily operating and maintenance costs.

5. Constant Temperature Fermentation System

Optional dimple cooling jacket and full-layer thermal insulation structure, matched with external temperature control equipment, stably maintains the best fermentation temperature of 22–28℃ all year round, ensuring consistent flavor of each batch of kombucha.

6. Diversified Customization & Wide Compatibility

Supports vertical cylindrical standard structure and customized conical bottom. Equipped with standard interfaces for sampling valve, discharge valve and liquid level monitoring. Compatible with manual brewing and semi-automatic production lines.
