Smooth Tomato and Vegetable Sauces
Define viscosity as solids hydrate, heating / cooling behavior, mixing uniformity and discharge. A product that pumps easily hot may impose a different cooling or end-of-batch transfer duty.
Compare kettle duty, heating / cooling cycle, texture-preserving transfer and filling before adding cooked-sauce production capacity.

Define viscosity as solids hydrate, heating / cooling behavior, mixing uniformity and discharge. A product that pumps easily hot may impose a different cooling or end-of-batch transfer duty.
Hydration, wall fouling, emulsification and shear history can change texture and heat transfer. Trial the demanding recipe through cook, cool and final package acceptance.
Specify the largest piece, solids load and accepted integrity after agitation, valves, pump and filler. Do not assess particle quality from a vessel sample alone.
Measure ingredient charging, heat-up, cooking, cooling, discharge and cleaning as a full cycle.
Review permitted holding, transfer, buffer and package states around the qualified preservation route.
Map ingredient additions, recipe authority, valves, cleaning transitions and restart.
Review each system by its operating duty and the interfaces to be agreed before procurement.
Product-specific cooked-sauce batch duty.
Approved ingredient / buffer interfaces.
Cook-room vessel / transfer circuits.
Specialist transfer / thermal / filling packages.

Compare cookers against the complete product envelope and cycle rather than purchase price per gallon. Require accepted quality at the final transfer / package and state what utilities, recipes, cleaning and commissioning are included. Use the approved product-specific preservation route when coordinating hot / cold holding and filling.

| Buying question | Evidence to prepare | Engineering decision |

| Larger cooker or faster complete cycle? | Good batches, full-cycle log and downstream availability. | Compare usable daily output. |
| Which texture is accepted? | Samples after heating, cooling, pumping and filling. | Trial the actual difficult recipe. |
| What does the cooker price omit? | Utilities, transfer, controls, cleaning, site and package. | Compare installed accepted-production scope. |
Start with the business outcome
A cooked-sauce plant needs the complete accepted batch cycle understood before selecting a larger cooker. DPS can coordinate configured kettles / vessels, utilities, transfer, recipe controls, CIP and packaging interfaces. The investment should release real good batches or paid costs while preserving recipe quality; nominal gallons and fastest heat-up alone do not establish the return.
Product formulation, required preservation, shelf-life and thermal / package release remain with qualified product and process specialists. Specialist shear, thermal and filling packages require explicit duties. Kettle cooking or hot filling alone is not represented as proof of shelf stability.
Define viscosity through heating and cooling, fouling behavior, largest pieces and accepted texture after the final package.
Measure charging, heating, mixing, cooling, discharge and waiting with representative sauces and the agreed utility duty.
Check particle integrity, retained product, package readiness and qualified recipe changes through pumps, valves and filling equipment.

Review the scope, cost assumptions and operating case for your project. The examples and calculators below support early planning and are not DPS quotations.
Use complete-cycle and quality evidence by recipe. Compare heat transfer, cooling, agitation, discharge or sequence corrections before adding cooker volume.
Define representative recipes, package / qualified preservation, batch train, utilities, hygienic routes, staffing and demand.

| Observed condition | Measure before design | DPS / team decision | Economic basis |
|---|---|---|---|
| Long full batch cycle | Actual stage times and good batch mass. | Target the limiting thermal / mixing / discharge duty. | Complete good output, capped by filler and demand. |
| Product retained / damaged | Matched input-output and quality after transfer. | Review agitation, passages and route. | Actual baseline purchase reduction or extra contribution once. |
| Recipe / flavor change loss | Qualified transition and first-good-product timeline. | Coordinate recipe, valves and cleaning. | Useful time and independent actual resource cost. |
| High steam / cooling expense | Metered baseline and utility recovery. | Compare source, distribution and heat-transfer correction. | Real bills after added service cost. |

| Decision | Targeted Work | Broader Scope |
|---|---|---|
| Batch Cycle | Correct the measured heating, cooling or discharge constraint. | Add or resize cooking capacity against the complete cycle. |
| Texture and Pieces | Trial agitation, passages and the transfer route. | Select different process packages when the product envelope cannot be retained. |
| Cook-to-Fill Balance | Coordinate discharge, buffers and package availability. | Integrate additional capacity across the limiting stages. |

| Product / process and interface engineering | $51,000 |

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.
Hypothetical owner-budget case: 250 days × 0.6 useful recovered hour/day × 1,000 good kg/h × 60% realization gives 90,000 incremental sold kg/year after the 110,000 kg demand ceiling. Net price $4.3/kg less incremental variable cost $2.8/kg gives $1.5/kg contribution. The baseline inputs assume $18,000 energy, $15,000 water / chemistry and $8,000 maintenance reductions per year. Avoided payroll is 0 hours × $40 × 0% cash realization. Verified baseline purchase reduction contributes $0; its basis is unchanged accepted baseline output. Deduct $18,000 added annual fixed cost. Result: $158,000 steady net benefit; initial cash $606,250 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 $158,000; year-one net cash $96,400; cash payback 4.23 years; five-year NPV at 10% is −$63,306. 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.

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.
The default reproduces the main retrofit energy input of $18,000/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.
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.
