Temperature-dependent thick sauces
Record viscosity and flow behavior at the actual transfer temperatures and solids states, including startup. A single final-product viscosity reading can conceal the difficult part of the duty.
Viscous and particulate food transfer
Viscous food transfer systems.
Protect product and cycle time.
Specify pumps, valves, piping and discharge for the product’s actual viscosity, particles, temperature and accepted texture.
How DPS can scope the process and investment decision.
Start with the business outcome
Slow transfer, retained product and damaged pieces can turn an adequate cooker into a poor production system. DPS can coordinate pump / valve OEM duty, routing, vessel discharge, controls and cleaning. Compare accepted product after the full transfer with measured time and purchasing effects, rather than selecting a pump from one nominal flow value.
Specialist pump and valve suppliers establish their equipment curves, product passages and operating limits. DPS integration is not a claim to manufacture every pump type. Qualified teams confirm food-contact materials, cleaning and product-release requirements.
Product and operating requirements: materials, quality and equipment duty.
Soups and foods with pieces
Specify largest / smallest pieces, loading and required texture after pump, valves and filler. A pump’s passage dimension alone does not establish acceptable particle damage.
Shear-sensitive or aerated products
Check suction, agitation, recirculation, entrained air and transfer history. A successful water test does not predict quality with the production recipe.
Compare the process sequence, equipment options and interfaces.
Survey suction, outlet geometry, restrictions, valve positions and controls before specifying more pump capacity.
Measure dischargeSeparate vessel and piping time.
Inspect suctionCheck available feed and conditions.
Find restrictionsReview valves, bends and filler entry.
Retest productMeasure quality and accepted mass.
Resolve before procurementA faster pump can move the constraint or damage product when the passage / feed problem remains.
Assess suitable centrifugal, rotary positive-displacement or other specialist packages on the same product and complete duty.
Define the envelopeTemperature, viscosity, particles and rate.
Review OEM curvesInclude suction and pressure limits.
Trial the recipeUse worst-case product conditions.
Agree acceptanceCheck quality, flow, residual and cleaning.
Resolve before procurementSelect from qualified evidence, not a blanket claim that one pump is always gentler.
Evaluate drainability, displacement or recovery concepts with the qualified product and sanitation team.
Weigh baseline residueUse a defined product / route.
Define recoverySeparate saleable, rework and waste.
Verify transitionConfirm routing and cleaning.
Reconcile purchasesCompare unchanged baseline output.
Resolve before procurementDo not count the same recovered product as both full purchase saving and extra sales.

Compare operating corrections, retrofit and replacement.
Survey the installed outlet, pump, valves and filler restriction at representative recipes and temperatures. Prioritize the actual restriction over a larger nominal flow rating.
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.
Define the product envelope and vessel / pump / piping / filler train together. Include drainage, recovery, service access and cleaning in the layout and cost.

Worked operating case
Hypothetical screening case: 250 days × 0.3 equivalent useful hour/day × 1,000 accepted kg/h × 60% realization, capped at 60,000 kg incremental demand, gives 45,000 additional sold kg/year. Net price $3.8/kg less incremental variable cost $2.5/kg gives $1.3/kg contribution. Verified baseline purchase savings are $11,520, realized payroll savings $0, energy $4,000, cleaning resources $6,000 and maintenance $5,000 per year. Deduct $8,000 additional annual fixed cost. Recovered material is valued only through verified baseline purchases; incremental sold product already includes its material cost in variable contribution.
Calculated from these assumptions: steady annual net benefit $77,020; year-one net cash $47,263; cash payback 4.29 years; five-year NPV at 10% is −$36,085. 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.

| Base | $77,020 | −$36,085 | 4.29 years |
| Upside | $92,522 | $17,749 | 3.63 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.
Baseline transfer-loss purchasing worksheet

Viscous and particulate food transfer project FAQ
Can pump passage size predict piece integrity?
It is one input. Product fragility, clearances, speed, pressure, valves and downstream restrictions also affect damage. Trial the complete route.
Does higher flow always improve ROI?
Only if the transfer is the actual constraint and additional accepted output can be sold or paid cost is removed. Extra flow into a blocked filler has no automatic benefit.
How should recovered product be valued?
Define whether it replaces purchased inputs at unchanged output or produces extra sold output. Use the appropriate cost / contribution once and follow the qualified recovery rules.
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.
