Required conditions during real demand
Use equipment and qualified product / cleaning requirements at realistic production overlap. Define source and point-of-use conditions with synchronized time records; daily totals can hide constraining peaks.
overlapping production and cleaning thermal loads in food plants
Production & CIP utility peaks
Measure simultaneous duty.
Production or cleaning loses required conditions during simultaneous heat / cool requests even though average utility use appears to be below nameplate capacity.
How DPS can scope the process and investment decision.
Start with the business outcome
Production or cleaning loses required conditions during simultaneous heat / cool requests even though average utility use appears to be below nameplate capacity. Build synchronized demand, supply / return and recovery records. Compare feasible sequencing, distribution correction, storage / recovery and source capacity, while preserving approved product and cleaning requirements. DPS can connect the process basis, capital alternatives, field / supplier interfaces, controls and project execution so the owner can make a reviewable investment decision.
DPS publishes utility-related engineering and installation scope. Specialist source packages, refrigerant / pressure-system work, electrical design, process water and local approvals require explicit qualified parties. No universal energy saving or capacity uplift is claimed.
Utility upgrade requirements: source, distribution and point of use.
Distribution, return and recovery

Production and CIP thermal peaks: why the average is insufficient.
Hypothetical equivalent thermal-duty snapshot: production requests 500 kW and CIP 300 kW against 700 kW of available delivered source duty. Their overlap requests 800 kW, leaving a 100 kW gap. If qualified scheduling permits separation, the illustrated peak is 500 kW rather than 800 kW; recovery, distribution and return conditions must still be proved. These example kW values are not a boiler / chiller design or a validated cleaning duty, and they do not independently establish the main model’s energy or output benefits.

Worked operating case
Hypothetical case for overlapping production and cleaning thermal loads in food plants: 250 days × 0.5 useful hour/day × 1,000 accepted kg/h × 60% realization gives 75,000 kg potential extra sales; the 90,000 kg demand ceiling yields 75,000 sold kg/year. Net price $4.20 less $2.70 incremental variable cost gives $1.50/kg contribution. Separately verified baseline energy / cleaning / maintenance assumptions are $68,000/year; actual paid-hour avoidance is $0/year. Added fixed operating cost is $18,000/year, and year-one gross benefit realizes at 75%. These values are original owner-planning assumptions, not supplier prices or a customer result.
Calculated from these assumptions: steady annual net benefit $162,500; year-one net cash $117,375; cash payback 4.27 years; five-year NPV at 10% is −$73,770. Change the assumptions below to test a different case.

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.
Utility baseline energy and added service worksheet
Default gross saving is 5,000,000 kWh × 10% × $0.12 = $60,000/year, the main energy field. This narrow worksheet deducts $6,000 service to show $54,000 net; that $6,000 is included within the main $18,000 added fixed operating cost and must not be deducted twice.
Commissioning tests and performance acceptance.
Agree the design basis.
Use representative products, measured constraints and a documented utility / cleaning envelope. Assign each supplier and owner interface.

Food Plant Production and CIP Heating Cooling Peak Loads FAQ
Why can CIP disrupt production when average utilities look adequate?
Build synchronized demand, supply / return and recovery records. Compare feasible sequencing, distribution correction, storage / recovery and source capacity, while preserving approved product and cleaning requirements.
Should heating and cooling loads be summed at nameplate?
Log actual event times, load basis, source and point-of-use conditions, return and recovery. A utility average cannot size short shared peaks; a new source cannot compensate for an unidentified downstream restriction.
Can rescheduling replace a boiler or cooling expansion?
Meter current delivered conditions and baseline costs before selecting equipment. Extra-volume utilities stay in incremental variable cost. DPS publishes utility-related engineering and installation scope. Specialist source packages, refrigerant / pressure-system work, electrical design, process water and local approvals require explicit qualified parties. No universal energy saving or capacity uplift is claimed.
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 overlapping production and cleaning thermal loads in food plants project 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.
