Types of 7 BBL jacketed fermenter
While most fermenters share fundamental functions for hosting yeast activity, choices around conical vs cylindrical profiles, chilling methods, and levels of automation provide options when specifying equipment.
Table 2: Types of 7 BBL Fermenters
| Types | Attributes | Considerations |
|---|---|---|
| Conical bottom | Angled cone walls and collection point | Easier yeast harvesting |
| Cylindrical | Straight walls and flat bottom | Simpler construction, easier cleaning |
| Single wall | No exterior temperature control layers | External chilling needed |
| Jacketed | Hollow walls for running glycol/liquids | Tighter temperature control |
| Cooling systems | Glycol, Freon, CO2, chilled water | Infrastructure, environmental factors |
| Control systems | Manual vs programmable | Precision, labor factors |
Key decisions around fermenter cone angles, jacket layers, chilling systems, and automation levels provide avenues for customization catering to brewers’ specific workflow, infrastructure, quality, and budget situations when investing in cellar equipment.
Overview of the Commercial Beer Brewing Process
In typical commercial beer production environments after the mashing and boil stages, fermenters host critical biochemical reactions:
- After boiling, hot wort is rapidly chilled then transferred into fermenters.
- Yeast is pitched into cooled wort to initiate the fermentation stage. Key transformations include:a. Yeast metabolizing sugars into alcohol which serves as both a product and preservativeb. Carbon dioxide getting produced as a metabolic byproduct providing natural carbonationc. Diacetyl and other flavor/aroma compounds evolving from yeast activityd. Settling of heavier yeast and proteins to the fermenter cone bottom
- Temperature control provided by insulated, jacketed walls maintains ideal conditions for healthy fermentation.
- Yeast may get harvested and repitched to save costs before beer moves to conditioning tanks, gets filtered, and packaged.
Careful fermenter stage monitoring and temperature modulation ensures properly attenuated beer reaching desired alcohol levels with balanced flavors, carbonation, clarity, and quality attributes meeting branding objectives.

FAQ
Q: How much floorspace should a brewer allocate for 7 BBL fermentation equipment?
A: Expect 500-1,000+ square feet for multiple 7 barrel fermenter units plus cleaning/transfer spaces around the vessels and associated infrastructure.
Q: What level of glycol chilling capacity is ideal for 7 BBL sizes?
A: A good rule of thumb is to spec glycol chilling systems capable of pulling heat equivalent to around 4-5 times the batch size. So for 7 BBL units, target 28-35 BBL equivalent chilling power.
Q: What are early indicators of potential contamination or infection?
A: Off aromas, surface films, excess foaming, ropey yeast strands, changes to color, clarity or hop/malt balance can reflect undesired bacteria getting established in fermenters.
Q: Should brewers favor conical or cylindrical fermenters for 7 BBL batches?
A: Conicals simplify yeast harvesting but add fabrication complexity. Cylindrical tanks more easily accommodate future expansion. Evaluate workflow priorities as needs evolve over longer timeframes.
Q: How long can a professionally engineered 7 BBL fermenter remain productive?
A: With appropriate daily cleaning procedures plus routine maintenance replacing gaskets, sensors, cooling lines etc annually, 20+ years of service should be expected from quality stainless steel fabrication assuming no excessive mechanical damage or abuse occurs.
