Milk throughput, product mix, pasteurization hours, CIP cycles, cold-room occupancy and shutdown windows.
Dairy plant energy audit checklist
Audit refrigeration, pasteurization, CIP and heat recovery as one dairy energy boundary.
This field-ready checklist shows what to collect, what to calculate and where dairy energy savings are commonly double-counted. It is a pre-audit method, not a substitute for site measurement.
Minimum data set
Collect these records before estimating savings.
Electricity and fuel bills, refrigeration compressor data, boiler efficiency, air-compressor data and interval demand.
Milk inlet/outlet temperatures, chilled-water or refrigerant conditions, CIP supply/return temperatures and hot-water demand.
Five audit checks
Questions the pre-audit must answer.
Separate process cooling, cold storage, low-load operation, condensing conditions and defrost before assigning savings.
Confirm actual heat-regeneration effectiveness before claiming utility reduction.
Cap recoverable heat by simultaneous sanitary hot-water demand, usable temperature and exchanger isolation.
Check combustion, condensate, distribution loss and storage before adding heat-recovery value.
Do not add condenser heat, compressor heat and boiler savings against the same hot-water demand.
Decision boundary
Replace representative values before investment use.
A site-specific report needs plant production, utility bills, equipment data, operating trends and sanitary constraints. Public example values show the method only.
