closed kombucha fermentation tank

Product Overview

Closed kombucha fermentation tank is the core standardized equipment for modern industrial kombucha brewing. Different from traditional open brewing containers, this sealed fermenter adopts a fully enclosed sanitary structure with adjustable sterile air intake system, which can accurately control the oxygen content required for kombucha fermentation, effectively reduce the rate of mold and miscellaneous bacteria pollution, greatly improve the pass rate of finished products and flavor repeatability.

It can realize two working modes: controlled aerobic primary fermentation (cultivate SCOBY and ferment base tea) and fully sealed anaerobic secondary fermentation (carbonation flavoring). Equipped with temperature regulation, pressure monitoring, sampling ports and CIP cleaning interfaces, it is the preferred fermentation equipment for medium and large kombucha manufacturers, beverage startups and OEM production workshops.

Core Advantages of Closed Kombucha Fermentation Tank

1. Sealed anti-pollution design, low failure rate

Full sanitary seal + HEPA high-efficiency filter breather valve, only purified air enters the tank, completely isolate external pests, mold spores and sundry bacteria, solve the biggest pain point of open kombucha brewing easy to go bad.

2. Precise oxygen control, stable SCOBY activity

Adjustable air intake valve manually controls oxygen supply volume, neither excessive oxidation leading to sour taste, nor oxygen shortage causing SCOBY inactivation, keep the fermentation process stable every batch.

3. Constant temperature jacket system, standardize flavor

Optional dimple glycol cooling jacket + polyurethane insulation layer, lock fermentation temperature at the optimal 24~26℃ all year round, avoid flavor fluctuation caused by seasonal temperature changes.

4. Sanitary stainless steel material, easy full cleaning

Inner wall mirror polishing Ra≤0.4μm, no dead corners for dirt accumulation; conical cone bottom drains residue completely, matched with 360° rotating CIP spray ball, realize automatic cleaning without manual tank entry, meet food GMP hygiene standards.

5. Multi-functional dual-purpose for primary and secondary fermentation

Switch freely between aerobic fermentation mode and sealed pressurized carbonation mode, one tank completes base fermentation and sparkling kombucha maturation, reduce equipment investment cost.
