Food Extrusion Calculators
Six focused production planning tools for extruder capacity, pasta throughput, moisture balance, expansion, pet food cost and fish feed cost. Use the estimate to frame the next technical discussion.
Results are planning estimates. Final equipment selection still requires material data, process testing, utility review and a project-specific quotation.

Use them together: define output, check process conditions, then estimate operating cost.
Choose a Calculator by Planning Question
The tools answer different parts of a food production line project. Choose the question closest to your current decision instead of opening all six calculators at once.
How much can the line produce?
Start with extruder capacity or pasta production capacity when output and equipment size are still being compared.
Will moisture and expansion stay under control?
Check pre-conditioning water and steam needs, then evaluate physical expansion and density after the die.
What could the product cost?
Estimate pet food or fish feed manufacturing cost, batch cost, gross margin and machinery payback.
Capacity & Throughput Calculators
Use these two tools when comparing screw configurations, drive power or equipment scale against a required hourly or daily output.
Food Extruder Capacity Calculator
Estimate hourly and daily output for a single-screw or twin-screw food extruder from machinery dimensions, motor power and formulation factors.
Inputs: extruder type, screw diameter, main motor power, screw speed, formulation and die size.
Results: kg/hour, lb/hour and estimated metric tons per 24-hour day.
Pasta Production Capacity Calculator
Estimate pasta throughput from extruder power, screw diameter, dough moisture, operating hours, OEE and target product shape.
Inputs: motor power, screw diameter, dough moisture, daily operation hours, efficiency and pasta shape.
Results: extruded kg/hour, estimated tons per day and tons per month based on 25 operating days.
Process Control & Product Quality
Use these tools to examine pre-conditioning moisture and the physical expansion or density of the extrudate.
Food Extrusion Moisture Balance Calculator
Estimate the moisture that must be added before extrusion and separate the requirement between liquid water and steam condensation equivalent.
Inputs: incoming feed rate, initial moisture, target processing moisture and steam contribution.
Results: total moisture addition, water injection, steam equivalent, conditioned material flow and dry solids flow.
Extrusion Expansion Ratio Calculator
Compare die diameter, extrudate diameter and density to estimate physical expansion and density reduction in puffed or textured products.
Inputs: die diameter, product diameter, unexpanded density and final bulk density.
Results: diameter expansion ratio, volumetric expansion ratio and density reduction.
Cost & Profitability Calculators
Use the application-specific cost tools to compare operating cost, batch exposure, gross margin and estimated machinery payback.
Pet Food Production Cost Calculator
Build a preliminary manufacturing cost and profitability estimate for an extruded dry pet food line, including yield loss, overhead and equipment depreciation.
Inputs: line output, schedule, raw material, utilities, labor, packaging, investment, depreciation and selling price.
Results: cost per kg, gross margin, payback period, batch cost breakdown and monthly output and profit.
Fish Feed Production Cost Calculator
Estimate aquafeed operating cost per ton and total batch cost using feed type, raw material price, energy, labor, wear parts and losses.
Inputs: feed type, raw material cost, batch and annual volume, utilities, labor, equipment life, maintenance and packaging.
Results: cost per ton, total batch cost, raw material share and a detailed cost breakdown.
How to Use These Production Planning Tools
The calculators are most useful when their outputs feed each other. Capacity sets the production scale. Process checks define operating conditions. Cost turns those assumptions into a project baseline.
Define product and output
Set the target product, hourly output and operating schedule before comparing machine sizes.
Check process conditions
Use moisture and expansion tools where formulation, steam or product density affects the result.
Build a cost baseline
Add raw material, energy, labor, packaging and equipment assumptions to estimate cost per unit.
Validate the project
Review the estimates with the engineering team and confirm them against material testing and final line design.
Calculator Limits and Engineering Review
- Capacity results depend on material moisture, screw configuration, die open area and thermal-mechanical input.
- Moisture and expansion results require process details and should not be treated as final setpoints.
- Cost models use the assumptions you enter and do not replace local quotations, taxes or plant measurements.
- Final line selection should include material testing, utility review, layout planning and a project-specific quotation.
