Set Yogurt
Fermentation and setting in the package create a different equipment / residence and movement basis from stirred products. Confirm the selected packaging, incubation and cold-side responsibilities.
Yogurt & Cultured Dairy Engineering
Balance mix preparation, fermentation occupancy, texture handling, cooling, fruit addition and filling before expanding cultured-dairy capacity.

Yogurt & Cultured Dairy Production Requirements and Product Variants.
Stirred and Fruit Yogurt
Texture can change through cooling, pumping, holding and fruit addition. Specify accepted viscosity / structure and particle integrity after the complete train, not only at the fermentation vessel.
Concentrated Cultured Products
Straining or membrane concentration introduces specialist separation, permeate / waste and different mass balances. Count final accepted product mass and actual input / by-product economics.

Yogurt & Cultured Dairy Equipment Selection: Resolve the Operating Duty First.
A yogurt equipment tender should distinguish set, stirred and concentrated routes. Require a product-matched occupancy schedule and final texture acceptance before comparing tank volume, pump rate or filler output. Include the cold side and shared cleaning duty because either can prevent an otherwise adequate package from producing saleable product.

| Buying question | Evidence to prepare | Engineering decision |

| Which asset limits the calendar? | Fermentation / release, cooling and package access. | Compare usable occupancy rather than fill rate. |
| Can transfer rate increase safely? | Qualified texture / fruit integrity after the full train. | Trial pump, route and cooling interfaces. |
| Is concentration included? | Specialist separation, final-product mass and by-product basis. | Define OEM duty and complete economic boundary. |
Engineering the Whole Line
Start with the business outcome
A yogurt line can be constrained by fermentation occupancy, cooling recovery, gentle product transfer or package access rather than vessel size alone. DPS can assess the process / utility / controls and installation interfaces around the qualified cultured product. The business case must distinguish approved residence, usable accepted product and actual costs from an assumed shorter fermentation.
Culture selection, fermentation endpoint, product texture, preservation, shelf-life and product release require qualified dairy specialists. Homogenizers, specialist heat exchangers, separators and filling packages have explicit OEM responsibilities; no universal culture or treatment parameters are supplied.
Commissioning Tests and Performance Acceptance.
Define the Cultured Product Route
Separate set, stirred, fruit and concentrated products, including fermentation location, residence, cooling and specialist separation responsibilities.

| Separate one-time startup / shutdown cost | $45,000 |
| Incremental working capital | $25,000 |
| Total initial cash | $645,000 |
The defined scope assumes applicable freight, procurement charges and taxes are included in the owner’s estimate. Add missing civil, land / shell, OEM, environmental, validation and permitting costs explicitly. Site and field conditions, duty, production access and quoted supplier scope determine actual price. Financing is excluded.
Worked Operating Case
Hypothetical owner-budget case: This conservative utility / integration case assumes no incremental product sales; productive time, good-output rate and demand are all zero. Product quantity alone does not establish a profitable output gain. The baseline inputs assume $40,000 energy, $22,000 water / chemistry and $18,000 maintenance reductions per year. Avoided payroll is 800 hours × $40 × 50% cash realization. Verified baseline purchase reduction contributes $0; its basis is unchanged accepted baseline output. Deduct $20,000 added annual fixed cost. Result: $76,000 steady net benefit; initial cash $645,000 includes the separate site, contingency, startup and working-capital inputs. These are original illustrative assumptions, not a quotation, price benchmark or achieved DPS result.
Calculated from these assumptions: steady annual net benefit $76,000; year-one net cash $52,000; cash payback Beyond 5 years; five-year NPV at 10% is −$378,718. Change the assumptions below to test a different case.

Replace the illustrative inputs with your own measured or quoted values. The five-year pre-tax model uses good kilograms, demand-capped contribution and separately verified baseline savings; it is not a project quotation.
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 | $76,000 | −$378,718 | 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.
Calculation Basis
- Five-year, pre-tax cash flow. Financing, depreciation and asset resale are excluded.
- Initial cash includes contingency, startup costs and working capital; year one reflects ramp-up.
- Output is capped by demand. Count each production gain or verified cash saving once.
Yogurt & Cultured Dairy Baseline Energy-Cost Worksheet
The default reproduces the main retrofit energy input of $40,000/year before added maintenance. The narrow worksheet is not a product-process calculation and does not automatically transfer values into the ROI model. Additional annual service is included in the main added-fixed-cost allowance; deduct it once.

Yogurt & Cultured Dairy Equipment and Plant Upgrade FAQ.
Should fermentation time be treated as lost production time?
Only if a qualified product / process assessment establishes a feasible change. Required residence is part of the product, not automatically a recoverable loss.
Does a larger pump improve yogurt throughput?
Check texture, product quality, cooling and package access. A faster pump that damages accepted structure does not increase good output.
Can set and stirred yogurt share the same line plan?
Their process and package residence / handling differ. Define what can be shared and what specialist duties remain separate.
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.
