Enhanced Safety

Sealed systems with proper venting protect workers from CO2 exposure while preventing contamination. Professional tanks include safety features such as pressure relief valves and gas monitoring systems.

Applications of Fermentation Tank

Biopharmaceuticals

Producing antibiotics, vaccines, biological enzymes, monoclonal antibodies, etc.
Food Industry

Stainless steel beer fermentation tank for brewing beer, alcoholic beverages, yogurt fermentation tank, yeast extracts, etc.
Chemical Industry

Preparing chemical products such as amino acids, organic acids, and biofuels.
Agriculture

Producing microbial fertilizers, biopesticides, etc. to promote the development of ecological agriculture.

Types of Fermentation Tanks

Conical Fermentation Tanks
These tanks feature a conical bottom structure, which facilitates the discharge of sediment. They are commonly used in the production of beer, wine, and other products requiring high clarity. This design allows yeast and impurities to naturally settle at the bottom, making removal convenient and improving product clarity.

Flat-Bottom Fermentation Tanks
With a simple structure and relatively low cost, these tanks are suitable for small-scale production or non-alcoholic fermentation processes such as kombucha and yogurt. Although their functionality is relatively basic, they offer excellent cost-effectiveness in applications where complex sediment removal is not required.

Cylindroconical Fermentation Tanks
These tanks combine a cylindrical body with a conical bottom structure and are suitable for large-scale industrial production, balancing efficiency and functionality. They are currently the most commonly used type in craft brewing and industrial fermentation.

Open Fermentation Tanks
This is a traditional structure that allows contact with air and is suitable for certain ale beers and specific flavor fermentation processes. Open fermentation can create unique flavor characteristics, but it requires stricter environmental control.

Closed Fermentation Tanks
These tanks feature a fully sealed structure and allow fermentation to occur in an oxygen-free environment. They are commonly used for lager beer, cider, and other oxygen-sensitive products. The closed design effectively prevents oxidation and contamination.

Components of Fermentation Tank

Tank Body: It is the main container for the fermentation process, which can range from tens of liters to hundreds of thousands of liters depending on its capacity. It is designed with an insulation layer to maintain a constant fermentation temperature.

Mixing System: Composed of an electric motor driven agitator and a stirring paddle, it is used to mix culture medium and microorganisms, increase dissolved oxygen, and promote uniform distribution of microorganisms.

Ventilation and Exhaust Device

Provide oxygen to microorganisms while eliminating metabolic products such as carbon dioxide to maintain a stable gas environment.

Temperature Control System

Adjust the temperature inside the tank through electric heating sleeves, cooling coils, and other equipment to accurately control the fermentation conditions.

Sensors and Controllers

Monitor and regulate parameters such as pressure, pH value, and dissolved oxygen concentration inside the tank to achieve automated management of the fermentation process.

Packing & Delivery

Delivery & Transportation

All delivery terms are available: EXW, FOB, CIF, CFR, DAF, DDP, CIP, etc.
Shipped in 45 days after the deposit confirmed.

Packing

Adopt steel frame/plywood/frame/palle/seal boxes to fasten each main component, avoiding movable damage via transportation, and make it easier for clients to unload the cargo.
