Milk temperature, receiving schedule and storage tanks establish refrigeration base load before production starts.
Dairy processing integrated-energy audit example
Pasteurization, refrigeration, CIP hot water and cold storage diagnosed as one dairy energy system.
This case shows how a dairy processing facility should be reviewed from the process boundary first: raw milk cooling, pasteurization, product cooling, chilled storage, CIP hot water, boilers, compressed air and electrical demand.
- Starts from dairy process operations before estimating savings.
- Separates refrigeration electricity, thermal fuel reduction and heat-recovery offsets.
- Protects the sanitary boundary for CIP and pasteurization temperature validation.

Why dairy heat-recovery savings are often double-counted
This engineering walkthrough explains how to audit pasteurization, refrigeration, CIP hot water, boilers, compressed air and heat recovery as one dairy energy system. It uses representative example values only; site-specific plant data should replace the sample inputs before project decisions.

Watch the method first, then open the example workflow and replace sample values with site-specific plant data.
Process boundary first
Dairy energy opportunities come from heating and cooling the same product stream.
A dairy case cannot be treated as a generic refrigeration or boiler calculation. Pasteurization regeneration, product cooling, CIP hot water, cold storage and sanitary operation define what can be saved and what must be validated on site.
Pasteurization and plate heat-exchanger regeneration determine both hot utility demand and downstream cooling load.
Yogurt or fresh dairy batches can add temperature-control windows that interact with refrigeration staging.
Valves, instruments, packaging and filling air create a secondary compressed-air opportunity with reliability constraints.
Cold-room temperature, doors, defrost and storage turnover keep refrigeration running outside production hours.
CIP hot-water timing and temperature cap how much condenser or compressor heat can be reused.
Energy-flow map
The report keeps refrigeration, heat recovery and sanitary hot water separate.
The plant may need heat and cooling in the same production window. The report separates physical electricity savings, fuel reduction, avoided heat utility and demand-charge effects before showing the project total.
Product safety and cold-chain quality define which energy measures are acceptable.
Evaporating temperature, condenser control, cold-room doors and low-load sequencing drive electricity savings.
Plate heat-exchanger effectiveness and CIP hot-water demand set the thermal target gap.
Combustion, return temperature, condensate or hot-water loop losses remain thermal-side measures.
Pressure, leakage and dryer losses are reviewed as secondary electricity measures.
Peak coordination is shown separately from kWh reduction.
Recovered heat can preheat utility water only within the validated sanitary boundary.
Diagnosis result structure
What the dairy workflow produces.
The assessment maps the dairy process into the same pre-audit report structure used across kWhScan: baseline, target gap, equipment, controls, distribution, multi-energy boundary, measure priority and M&V.

Evidence basis
Public references support the process-energy boundary.
The page does not rely on a named customer logo. It exposes the engineering basis: public dairy energy references, equipment behavior, report calculations and user-replaceable site values.
Used to support the presence of material refrigeration, process heat, motor and utility opportunities in dairy facilities.
Open public referenceWhere the public page shows opportunity logic, the assessment report labels confidence and lists the data needed to improve precision.
The workflow is designed for utility bills, operating hours, equipment data and optional trend logs from the user's own site.

Before running the workflow
What a dairy user can judge before running the workflow.
This page shows the industry-specific signals used in the detailed diagnosis report, so a visitor can judge relevance before entering site data.
Visible signalWhat it tells the user
Process signal
PHE approach temperature, fouling, product flow and regeneration outlet temperature are named before heat-recovery savings.
Energy signal
Refrigeration, CIP hot water, boiler fuel and plant air are separated before totals are added.
Boundary signal
CIP and pasteurization validation stay outside the energy-saving claim.
