Sauce changeover & recipe-control upgrades
Sauce line changeover upgrades
Recipe controls & useful capacity.
Evaluate cleaning, recipe management, product recovery and restart as a targeted sauce-line improvement before buying additional cooking capacity.
How DPS can scope the process and investment decision.
Start with the business outcome
A sauce manufacturer with growing SKU complexity can lose capacity between batches even when the kettle meets the cooking duty. DPS can coordinate process, controls, piping, vessels and CIP interfaces to address the verified changeover constraint. The business case should value real extra sales, independently verified baseline material reduction and avoided paid cost without counting the same recovered product twice.
Qualified recipe conditions, allergen / cleaning verification, product preservation and release remain the responsibility of the designated product and site teams. This guide does not represent a controls change as proof of shelf stability or a guarantee of product quality.
Sauce changeover projects need a defined transition matrix.
Color, flavor and allergen transitions
Classify the actual sequence and site-approved verification requirements. A convenient production sequence cannot override the required transition procedure.
Recipe and package transitions
Separate dosing / recipe parameters from filler setup and downstream package tasks. A shorter recipe download does not remove a filler bottleneck.
Sauce line changeover: distinguish recipe, recovery and cleaning work.

Compare operating corrections, retrofit and replacement.
Use the transition matrix, good-output baseline and actual recipe change record. Correct a verified sequence or transfer problem while retaining equipment that meets its duty.
Investment boundaryThe illustrative default includes only measured productive time, independently reduced baseline purchases and partial payroll realization. Extra-volume ingredients and labor stay inside variable cost.
Add capacity when cooking / mixing remains limiting after feasible corrections and the transfer, CIP and filler schedule can use it. Define the new recipe and package envelope.
Investment boundaryInclude new vessel / agitator duty, source and return utilities, OEM interfaces, controls, installation, qualified trials and working capital. Compare the whole train.

| Valve / transfer / instrumentation changes | $75,000 |
| Mechanical and electrical installation | $45,000 |
| Recipe and sequence controls | $50,000 |

| Separate one-time startup / shutdown cost | $30,000 |
| Incremental working capital | $10,000 |
| Total initial cash | $327,500 |
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
Two qualified 15-minute transition improvements release 0.5 hour/day. At 250 days × 900 good kg/h × 65% realization, the example sells 73,125 extra kg/year at $1.60/kg contribution. A separate 0.6% verified reduction in 800,000 kg of baseline purchases at unchanged accepted baseline output avoids 4,800 kg × $2.30 = $11,040/year. This is a purchase reduction, not a 0.6-point change in a loss rate. The material worksheet also deducts $2,000 trial / disposal cost, included within the main model’s $10,000 added fixed operating cost; do not deduct it twice.
Calculated from these assumptions: steady annual net benefit $147,240; year-one net cash $100,068; cash payback 2.54 years; five-year NPV at 10% is $187,772. Change the assumptions below to test a different case.
Sauce line upgrade ROI: qualified time and verified purchases.
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.

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.

Sauce changeover & recipe-control upgrades FAQ
Will recipe automation fix slow sauce changeovers?
It can help when manual settings, sequence errors or missing interfaces are the measured cause. It cannot by itself remove required cleaning, ingredient preparation, filler setup or quality release.
Why use purchase reduction rather than loss percentage points?
At unchanged good output, actual purchases depend on the complete input / output balance. Directly multiplying the original purchases by a loss-rate point difference can misstate the saving. This model asks for the verified percentage reduction in purchases instead.
Should we buy another kettle?
Only after confirming that cooking / mixing remains the constraint and that transfer, cleaning, filling, storage and demand can use the additional batches. A targeted sequence or interface correction may address a different measured gap.
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.
Prepare a sauce changeover / recipe upgrade 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.
