Overview of 3 BBL Fermenter

3 BBL Fermenters are a common size for nano and microbrewery operations. Matching fermentation capacity to brewhouse size allows efficient beer production workflows.

This guide covers key considerations in selecting, designing, installing and operating 3 BBL Fermenter – variables that impact quality, throughput and scaling capacity cost-effectively.

Types of 3 BBL Fermenter

Standard 3 BBL fermenter vessels choices:

Type	Details
Conical Fermenters	Cone-shaped bottom collects yeast for easy removal. Accessories like cooling, carbonation.
Cylindroconical Fermenters	Hybrid allows some yeast removal. Conical add-on option.
Unitanks	Combined fermentation and conditioning tank. One vessel beer processing. Customizable.
Open Fermenters	Simple design usually square or circular. Cannot remove yeast easily. Lower cost.

Conicals and cylindroconicals allow yeast handling benefits but higher capital costs. Open top fermenters provide basic functionality at lower prices. Unitanks offer flexibility through integrated processing.

3 BBL Fermenter Design Factors

Key design considerations for 3 barrel fermenter systems:

Parameter	Recommendations	Customization
Dimensions	24-36″ diameter, 84-96″ straight side height typical	Varies with aspect ratio, conical bottom design
