Spring Roll Line Electricity and Operating Cost

A transparent worksheet that separates rated power, measured demand, energy and total operating cost.

Direct answer. Calculate line electricity cost from measured demand, not nameplate power alone: measured kW × operating hours × local tariff. Then divide total kWh by accepted output to obtain energy per 1,000 pieces. Add labor, cleaning, compressed air, consumables and wear parts separately; label any unmeasured example as illustrative.

Utilities: what is verified and what must be measured

Utility	How to use it	Status
Installed/nameplate power	Electrical design input; do not report it as kWh/h	Verified per model page
Actual demand and energy	Measure during a defined FAT recipe and stable interval	Buyer/test team must measure
Voltage/frequency	Confirm ordered configuration and destination supply	Configuration dependent
Compressed-air pressure	0.6-0.8 MPa on published complete-line models	Verified pressure; consumption unverified
Water and drainage	Derive from approved cleaning procedure and local rules	Buyer must confirm
Ambient range / IP rating	Do not assume tropical rating or IP65/IP66	No verified public value

Calculation framework

Estimated demand: nameplate kW × observed load factor. Energy: measured kW × hours. Electricity cost: kWh × tariff. Energy per 1,000 accepted pieces: total kWh ÷ accepted pieces × 1,000.

Illustrative calculation only: insert your own measured kW, hours, tariff and accepted output. This page does not present a SHENGXING measured energy result.

Do not mix these terms

Nameplate power: installed or rated load, not an hourly energy result.
Measured demand: instantaneous or averaged real power during a defined test.
Energy consumption per hour: kWh consumed in one operating hour.
Energy per 1,000 pieces: kWh normalized by accepted output.

Frequently asked questions

Is nameplate kW the same as hourly consumption?

No. Use measured demand over a defined operating period.

Can I compare energy per piece between tests?

Only when product, accepted-output definition, run duration and conditions are comparable.

Does this page publish a measured saving claim?

No. It provides an illustrative calculation framework until approved test records are supplied.

What should a formal test record include?

Machine configuration, raw material, output, run time, ambient conditions, calibrated meter and uncertainty.

Evidence and review: Product specifications come from the verified model records in docs/company-facts.json. Reviewed by SHENGXING Engineering Team on 2026-10-21. Commercial results and measured energy values are not stated without approved records.
