Smooth liquid foods
Define viscosity through heating / cooling, fouling, recipe variation and desired quality. The final package and the qualified route must be considered together.
Aseptic and retort food processing
Aseptic vs retort food processing.
Choose the qualified route.
Compare product treatment, particles, package, throughput, utilities and qualified acceptance before choosing an ambient-food processing route.
How DPS can scope the process and investment decision.
Start with the business outcome
Retort and aseptic systems create different product, packaging and supplier interfaces. DPS can coordinate the upstream process, specialist packages, utilities, controls and installation around the selected qualified route. The decision needs product / package trials and full installed economics; it cannot be resolved by comparing a cooker price with one retort or filler quote.
Qualified process authorities and specialist OEMs establish the required scheduled process, product / particle conditions, package suitability, validation and release. This guide does not recommend a universal lethal treatment or claim that DPS manufactures retorts or aseptic fillers.
Product and operating requirements: materials, quality and equipment duty.
Soups or sauces containing pieces
Particle dimensions, composition, loading and integrity can influence the required process and equipment. Test the complete train with the responsible specialists.
Pouches, trays, cans or other formats
Container material, geometry, seal quality, handling and package integrity can change thermal and mechanical requirements. A format change is not only a filler adjustment.

Worked operating case
Hypothetical screening case: 250 days × 0.5 equivalent useful hour/day × 1,500 accepted kg/h × 65% realization, capped at 150,000 kg incremental demand, gives 121,875 additional sold kg/year. Net price $4/kg less incremental variable cost $2.7/kg gives $1.3/kg contribution. Verified baseline purchase savings are $0, realized payroll savings $0, energy $15,000, cleaning resources $10,000 and maintenance $10,000 per year. Deduct $40,000 additional annual fixed cost. The default is an illustrative retrofit within a selected qualified route. It is not a price comparison between complete retort and aseptic plants.
Calculated from these assumptions: steady annual net benefit $153,437; year-one net cash $66,391; cash payback Beyond 5 years; five-year NPV at 10% is −$834,985. 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 | $195,423 | −$693,001 | 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.

Aseptic and retort food processing project FAQ
Is retort always cheaper than aseptic?
No universal price relationship is supplied. Product, package, duty, scale, site and supplier boundaries can change both capital and operating cost.
Can a particulate recipe use either route?
Only if the qualified product / package and equipment review establishes suitability. Particle dimensions and behavior need explicit specialist assessment.
Can a recipe change affect the process basis?
Yes. The responsible qualified team should assess recipe, particle, package and operating changes before adopting them in the approved process.
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.
