How much does it cost to process one tonne of steam-flaked corn?

A practical way to estimate the processing cost is to calculate five main expenses: electricity, steam, water, labor and packaging.

This guide uses reference consumption figures for a complete 10 TPH steam-flaked corn production line. You can combine these figures with your local prices to estimate the processing cost per tonne. A downloadable Excel calculator is also available to make the calculation easier.

How to Calculate Steam-Flaked Corn Processing Cost per Tonne

The calculation starts with a simple formula:

Processing cost per t + Steam + Water + Labor + Packaging

For the reference 10 TPH production line, the five expenses are calculated as follows:

For example, if your electricity price is 0.80 per kWh in your chosen currency:

Electricity cost per t × 0.80 = 5.00

The same method applies to steam, water, labor and packaging. Adding the five results gives the estimated processing cost per tonne under the reference conditions.

The calculation covers these five processing expenses. Raw corn purchases, equipment depreciation, maintenance, transportation and other expenses are calculated separately.

BellaEx has prepared a 10 TPH Steam-Flaked Corn Operating Cost Calculator to help you estimate processing expenses using your local prices.

Download the Operating Cost Calculator (Excel)

The spreadsheet includes English and Chinese calculation sheets, with a bilingual filling guide in the third worksheet.

How to Use the Calculator

1. Choose your language. Open the English or Chinese calculation worksheet. Each sheet works independently, so you only need to complete one.

2. Enter your local costs. Fill in the yellow cells with your currency, electricity price, steam price, water price, total labor cost for a 24-hour production day and packaging details.

3. Review the calculated results. The spreadsheet calculates the processing cost per tonne, for 10 tonnes and for the reference 240-tonne production day. The third worksheet,Fill-in Guide, explains the inputs in more detail.

Use the same currency and a consistent tax basis for all prices. If a cost is not yet known, the input can remain blank. Enter zero only when the expense is confirmed to be absent.

Reference Consumption for a 10 TPH Steam-Flaked Corn Line

The reference figures below were compiled from operating feedback provided in 2026 by 10 large customer factories using BellaEx equipment.

The reference configuration covers grain cleaning, soaking, steam cooking, flaking, steam-heated drying, cooling and packaging.

Here, 10 TPH means 10 tonnes of finished product per hour. At this production rate, continuous operation over 24 hours corresponds to 240 tonnes of finished product.

The figures reflect the following operating conditions:

Electricity: The reference covers production-line equipment, including machines that operate intermittently. Boiler electricity and shared auxiliary equipment are accounted for separately according to the project setup.

Steam: The approximately 4 tonnes per hour covers steam cooking and steam-heated drying, with a reference saturated steam pressure of 0.8 MPa.

Water: The reference of 1.25 tonnes per hour is the midpoint of a 1–1.5 tonnes per hour range. Process-water and boiler-makeup-water costs should be allocated according to the project's actual system.

These figures provide a starting point for budgeting. Actual consumption varies with corn moisture, ambient temperature, required finished-product moisture, equipment configuration and operating conditions. The 240-tonne daily figure is a calculation based on 24 hours at the reference production rate, rather than a guaranteed daily output.

A Few Details That Matter When Filling In the Costs

What should you enter for steam cost?

The calculator uses the total cost of one tonne of steam delivered to the equipment, rather than the purchase price of gas, coal or another fuel.

If your factory has its own boiler, the delivered steam cost can include fuel, water treatment, makeup water, boiler auxiliary electricity and relevant distribution losses. Costs already included in the steam price should not be added again under electricity or water.

For more information about steam demand, see our Steam-Flaked Corn Production Line Steam Requirement Guide.

How should electricity and labor costs be entered?

For electricity, use the applicable price per kWh. Where electricity prices vary throughout the day, a weighted average based on the expected production schedule can be used for the initial estimate.

For labor, the reference calculator uses the total cost of all workers and shifts over 24 production hours. When calculating actual operating costs, divide labor expenses by the qualified finished-product output produced during the same period.

What if the finished product is delivered in bulk?

If the finished corn flakes are discharged in bulk without bags, enter 0 for both the packaging bag price and the number of bags per tonne.

For bagged products, the number of bags depends on the packaging size. For example, 50 kg bags require 20 bags per tonne.

Can You Use the Same Calculation for a Smaller Production Line?

The calculation method also applies to smaller steam-flaked corn production lines. However, the consumption figures in this guide are based on the complete 10 TPH reference configuration.

A 1–5 TPH line may use a different arrangement for soaking, steam conditioning, drying and cooling. Its operating schedule and utility consumption may also differ. The 10 TPH consumption figures should therefore not be scaled directly by capacity alone.

The downloadable spreadsheet retains the fixed 10 TPH reference values. It is useful for understanding the calculation and comparing costs under different local prices. For a smaller or differently configured line, the same formulas can be used with consumption figures appropriate to that project.

For a plant already in operation, consumption per tonne can be calculated from electricity and steam meter readings and the qualified finished-product output recorded over the same period.

Estimate the Operating Costs for Your Project

If you're planning a steam-flaked corn production line, BellaEx can help review the utility consumption assumptions for your proposed configuration.

Your target capacity, daily operating hours, raw corn conditions and drying requirements can help establish a more relevant basis for the calculation.
