Different fermented beverages
Separate beer, kombucha and other products by actual recipe and operating requirements. Product names alone do not define compatible temperature, residence, cleaning or gas duty.

How DPS can scope the process and investment decision.
Start with the business outcome
A fermentation temperature-control project needs the product team’s required process and a realistic tank calendar. DPS can coordinate vessels, cooling, instruments, recipes and cleaning interfaces. Improved control may reduce actual resource or maintenance cost, but faster cooling is not automatically another released fermentation batch or a shorter biologically required process.
Qualified brewing / fermentation specialists define recipe conditions, organisms, residence, product release and pressure / gas-management requirements. DPS engineering and controls do not replace recipe development or manufacture every specialist fermentation package.
Product and operating requirements: materials, quality and equipment duty.
Tank sequence and occupancy
Count filling, fermentation, maturation or holding, emptying, cleaning and release in the tank calendar. A vessel unavailable to packaging remains occupied even after its process phase ends.
Peak cooling and return duty
Trend simultaneous tanks and utility recovery. A stable header reading can conceal poor conditions at a specific jacket or control valve.
Compare the process sequence, equipment options and interfaces.
Review source, distribution, jackets / exchanger, return and sensor behavior during real batches.

Investment boundaryThe preset is a hypothetical intervention in an existing operation. Defined capital scope, separate site additions, owner startup expense and working capital have different boundaries. Verify useful output, purchase reductions and payroll changes independently.
Model the full fermentation / maturation / packaging calendar, required vessel interfaces and peak services. Include laboratory / quality and product-release responsibilities in the owner’s operating plan.

Worked operating case
Hypothetical screening case: 250 days × 0 equivalent useful hour/day × 0 accepted kg/h × 0% realization, capped at 0 kg incremental demand, gives 0 additional sold kg/year. Net price $0/kg less incremental variable cost $0/kg gives $0/kg contribution. Verified baseline purchase savings are $0, realized payroll savings $10,800, energy $35,000, cleaning resources $10,000 and maintenance $8,000 per year. Deduct $12,000 additional annual fixed cost. The default deliberately assumes no additional sales. A tank-calendar study must establish complete additional released batches before a capacity benefit is entered.
Calculated from these assumptions: steady annual net benefit $51,800; year-one net cash $29,470; cash payback Beyond 5 years; five-year NPV at 10% is −$256,437. Change the assumptions below to test a different case.

All defaults are illustrative. The default case is an operating-plant improvement, not a greenfield quote. For a new operation, set baseline savings to zero and enter every additional operating and capital cost.

| Upside | $51,800 | −$256,437 | Beyond 5 years |
Downside: installed and site costs +20%, realization ×0.75 and unit contribution reduced by 20% of its absolute value. Upside: realization ×1.15, capped at 100%, and unit contribution improved by 10% of its absolute value. The demand ceiling still applies.
Formulas, scope and double-counting rules
Initial cash = (defined project scope + site additions) × (1 + contingency) + separate startup / shutdown cost + working capital. Contingency is conservatively treated as spent initially.
Sold incremental kg = min(days × recovered hours/day × constrained good kg/hour × realization, incremental demand). Contribution = sold incremental kg × (net price − incremental variable cost). New-volume labor, energy and packaging belong in that variable cost.
Baseline material benefit uses the verified percentage of actual purchases avoided at unchanged accepted baseline output. It is not a direct subtraction of two loss rates. Count a recovered kilogram once, either as its applicable cash saving or as incremental contribution.
Net annual benefit = contribution + independently realized baseline cash savings − added fixed operating cost. Year one scales gross benefits by the ramp factor while paying the full added fixed operating cost. Do not also count the same launch loss in the one-time startup amount.
Cash ROI = net annual benefit / initial cash. Five-year net ROI = (five-year cash inflows − initial cash) / initial cash. NPV = −initial cash + Σ cash flow(t)/(1 + discount rate)^t. Payback uses annual cash with linear interpolation within the recovery year. The threshold solver excludes terminal working-capital recovery.
This is a five-year screening horizon, not an asset’s entire life. No tax, debt, depreciation, grants, escalation, asset resale or additional replacement capital is modeled. Include recurring service costs in operating expense and use a detailed monthly budget for formal capital approval.
Fermentation cooling baseline-energy case
The defaults reproduce $35,000 gross annual baseline cooling savings in the main example. Its $12,000 added fixed cost includes all incremental service; no extra sales are inferred from this worksheet.

Fermentation temperature and batch systems project FAQ
Does faster cooling shorten fermentation?
It may correct an unwanted delay, but the qualified product process determines required residence and conditions. Do not treat biological process time as freely removable.
Why does the default have no capacity sales?
Because temperature control alone does not prove another complete released tank batch. The default only illustrates independent resource, maintenance and payroll effects.
Can several products share one fermentation system?
Review actual organisms / ingredients, product conditions, gas / pressure duty, cleaning and segregation requirements with the qualified team.
Are these prices or returns a DPS commitment?
No. The example inputs exist to make the business-case calculation reviewable. Actual scope, prices, schedule, savings and performance need project-specific assessment and agreement.
What should the first DPS conversation include?
Bring the product and package mix, operating baseline, commercial target, retained assets, site constraints, available outage window and the capital options you are considering. Mark unknowns for measurement or supplier trials.
Bring an operating baseline and a testable investment brief.
Prepare the information below, export the assumptions you have modeled, and discuss the unknowns with DPS. An unmeasured input is a question to resolve, not a reason to invent precision.
