A Field-Proven Engineering Guide for Frozen, Fresh, and Coated Fry Plants
A modern French fries production line is, at its core, a 14-stage continuous process that converts raw potatoes into uniform, golden, freezer-stable strips at throughputs ranging from 100 kg/h up to 5,000 kg/h. But here’s what most equipment brochures won’t tell you: 80% of your final product quality is locked in by just three stages — peeling, two-stage blanching, and par-frying. Get those right, and even an entry-level 300 kg/h line will out-perform a poorly tuned 1,500 kg/h plant. Get them wrong, and no amount of automation downstream will save you.
We take you through the entire engineering anatomy of a French fries line — process flow, core equipment, automation levels, plant layout, food-safety controls, and real CapEx/ROI math — based on the lines we’ve actually commissioned, not on theory. Whether you’re sizing a small-scale 200 kg/h frozen plant for a regional QSR brand, or scoping a 3,000 kg/h industrial export facility, you’ll find the operating parameters and selection logic you need to make a confident purchase decision.
What Is a French Fries Production Line? Definition, Scope, and Output Tiers
A French fries production line is an integrated, continuous-flow set of food-processing machines that transforms whole raw potatoes into one of three finished product formats:
- Frozen par-fried fries (the dominant 85% of global capacity, sold to QSR and retail freezer aisles)
- Fresh-cut chilled fries (short shelf-life, sold to local QSR within 7–10 days),
- Fully fried, seasoned, vacuum-packed snack fries (a small but high-margin segment for retail).
A complete line typically integrates 14 functional stages, 9 to 12 standalone machines, and a fully integrated control system (PLC + HMI for fully automatic configurations, or relay logic for semi-automatic builds).
The exact equipment count varies with output tier and product format — and choosing the right tier is the single most consequential decision in your project.
Output Capacity Tiers and Typical Investment
Based on the lines we’ve delivered globally, French fries plant configurations cluster into five distinct tiers. Use this table to anchor your own sizing conversation:
| Tier | Throughput | Target Buyer | Typical CapEx (EXW) | Footprint | Crew |
|---|---|---|---|---|---|
| Small Scale | 100–300 kg/h finished | Local QSR supplier, SME entrant | USD 110k–280k | 200–400 m² | 6–8 |
| Mid-Range | 500–1,000 kg/h | Regional brand, growing QSR chain | USD 380k–750k | 600–900 m² | 10–14 |
| Industrial | 1,500–2,000 kg/h | National brand, retail private label | USD 1.1M–1.8M | 1,200–1,800 m² | 15–20 |
| Large Industrial | 3,000+ kg/h | Export-oriented producer | USD 2.5M–5M+ | 2,000–2,500 m² | 18–25 |
| Snack/Coated | 100–500 kg/h | Branded snack producer | USD 150k–600k | 300–700 m² | 8–12 |
Throughput figures refer to finished frozen output, with a typical raw-potato-to-finished-fry yield of 48–52% (the rest leaves as peel waste, undersized scraps, blanch leachate, and frying moisture loss).
When evaluating a quotation, always confirm whether the stated capacity is “raw potato input” or “finished fry output” — we routinely see this misunderstanding inflate quoted capacities by nearly 2×.
Full Process Flow of a French Fries Production Line
Across every line we’ve commissioned, the standard flow follows the same logical sequence. The differences between a 200 kg/h plant and a 3,000 kg/h plant are not in the steps — they’re in the technology selected at each step.
Key operating windows we run on a typical 1,000 kg/h frozen line:
- Steam peeling: 1.0–1.6 MPa saturated steam, 50–100 kg per cycle, peel loss ≤ 8%
- Strip cutting: 6×6 mm or 9×9 mm cross-section, hydro-cutting at 3 kg/cm² for industrial scale
- First blanching: 90 °C × 3–5 minutes (polyphenol oxidase inactivation)
- Second blanching: 60 °C × 1–2 minutes (color stabilization, SAPP uptake)
- Hot-air drying: 8–10% surface moisture removal, 6 circulation fans, 1 exhaust fan
- Par-frying: 175–180 °C × 50–140 seconds depending on strip thickness
- De-oiling: vibratory + air-knife, target oil content < 8% on dry matter
- IQF freezing: chamber air −35 °C, core temperature −18 °C at exit, residence 15–45 minutes adjustable
The reason we hold the first blanching at exactly 90 °C, not 95 °C, is that above 92 °C you start gelatinizing surface starch too aggressively, which later causes oil pickup spikes during par-frying. The 60 °C second stage isn’t decorative either — it’s the SAPP (sodium acid pyrophosphate) absorption window that prevents the gray-blue discoloration you sometimes see in poorly engineered fries. These are the kinds of parameters most quotations skip, but they’re exactly what determines whether your fries pass a McDonald’s spec sheet or not.
Core Equipment Breakdown of a French Fries Production Line
Here’s how the major equipment specs scale across output tiers — the same logic applies whether you’re sourcing French fries machinery for a small frozen French fries plant or a complete industrial French fry production line.
Peeling: Brush vs. Steam
For lines below 500 kg/h: we recommend a brush roller peeler (4.5 kW, 9 imported nylon brush rollers, 1.8–2.0 m long, with auxiliary abrasive rollers). It’s mechanically simple, easy to maintain, and peel loss runs around 12–15%.
For lines at 1,000 kg/h and above: the economics flip in favor of steam peeling. Our standard LJP-300 unit handles 4–5 t/h of raw potatoes, runs at 1.0–1.6 MPa saturated steam pressure, and brings peel loss down to ≤ 8% — that 4–7 percentage-point yield gain typically pays back the steam peeler within 14–20 months at industrial scale.
Strip Cutting: Mechanical vs. Hydraulic
Mechanical strip cutters (Taiwan-imported, 7–10 mm adjustable, 200–300 kg/h per unit, 1.5 kW) handle small and mid-range duties cleanly.
Above 1,500 kg/h, hydro-cutting is the only credible option — high-pressure water transports potatoes onto a fixed stainless-steel blade matrix, eliminating mechanical stress, allowing 6×6 / 9×9 / specialty shape interchange, and sustaining 3,000–5,000 kg/h continuous throughput on a single cutter.
Blanching: Single-Stage vs. Two-Stage
Small lines often use a single electrically-heated blancher (36 kW, doubles as sugar-dipping for sweet-potato variants). Industrial lines run dedicated two-stage steam-heated blanchers with hydraulic belt-lift for cleaning, separate temperature/time controls, and inline SAPP dosing.
The two-stage architecture isn’t a luxury — it’s what separates fries that survive a 12-month frozen shelf life from fries that go gray in 90 days.
Par-Frying: The OpEx Battlefield
This is where line OpEx is won or lost. Our flagship 3,000 kg/h fryer configuration includes:
- External gas heat exchanger: 1.2 million kcal/h, multi-fuel capable (natural gas / LPG / diesel / heavy oil / methanol)
- Storage tank: capacity 1.3× fryer oil volume, with magnetic flap level indicator
- Dual coarse filters: ⌀500 mm, 10-mesh + 5×5 mm, A/B redundant, 12.5 m³/h circulation
- Inline fine filter: 80 L/min, 190 L chamber, 0.3–0.37 MPa, 2 paper filters/day
- Vertical tube oil cooler: connected to cooling tower, cuts post-shift cleaning wait time by 60–70%
- Automatic + manual fire suppression
- Tail scraper, side smoke hood, 5 cm aluminum-silicate insulation
This isn’t equipment over-spec — it’s what extends fryer oil life from a typical 3–4 days to 12–15 days, which on a 3,000 kg/h line saves roughly USD 180,000–240,000 per year in palm oil cost alone.
IQF Freezing
Mid-range plants (200–300 kg/h):
- Compact IQF cabinet
- Dimensions: 8,000 × 2,200 × 2,300 mm
- PID-controlled
- Bitzer 125 HP compressor
- Installed power: 250 kW
- Temperature accuracy: ±2 °C
Industrial plants:
- Freezing system: fluidized-bed tunnel freezers
- Insulation: 120–150 mm B1-grade polyurethane panels (density ≥ 40 kg/m³)
- Evaporators: aluminum-tube/aluminum-fin
- Variable fin spacing for long defrost intervals
- Refrigeration circulation: ammonia or freon pumps at 4:1 ratio
Six Engineering Advantages Built Into Our French Fries Production Line
Most French fries machinery looks similar. The differences only emerge after 12 months of production, when one line still hits spec and another fights oil quality, color drift, and unplanned downtime. Below are six engineering choices we make differently from the industry baseline.
1. Dual-Stage Steam-Heated Blanching with Inline SAPP Dosing
Most lines under 1,000 kg/h ship with a single-stage blancher. We standard-spec two independent tanks (90 °C × 3–5 min, then 60 °C × 1–2 min) with automated SAPP dosing down to the 500 kg/h tier.
Result: 12-month frozen shelf life without color drift, acrylamide consistently below the EU 500 µg/kg threshold.
2. 1.2 Million Kcal External Gas Heat Exchanger
Our par-fryer circulates oil through an external multi-fuel heat exchanger at ±2 °C precision, running on natural gas, LPG, diesel, heavy oil, or methanol on the same hardware.
Result: 30–40% extended fryer body life, plus fuel flexibility for markets where pipeline gas is unreliable.
3. Dual-Redundant Coarse Filter Plus Inline Fine Filter
Two coarse filter drums (⌀500 mm, 10-mesh + 5×5 mm, A/B redundant for hot-swap), plus an inline fine filter (80 L/min, 0.3–0.37 MPa).
Result: TPM held at 12–16% for 12–15 days versus the 3–4 day industry average — roughly USD 180,000–240,000 saved per year on palm oil for a 3,000 kg/h line.
4. Vertical Tube Oil Cooler for Post-Shift Cleaning
Standard fryers need 3–4 hours of natural cooldown before sanitation. Our vertical tube oil cooler drops temperature from 175 °C to handling-safe in 45–60 minutes.
Result: 200+ extra production hours per year, plus faster product changeovers.
5. Hydro-Cutter with Interchangeable Cutting Heads
High-pressure water (3 kg/cm²) transports potatoes onto a fixed stainless-steel blade matrix. 6×6 mm and 9×9 mm dies are quick-change, plus retrofittable specialty shapes (crinkle, wedge, shoestring). Single-machine throughput 3,000–5,000 kg/h.
Result: lower starch leaching, fewer broken strips, format flexibility without re-engineering.
6. Fluidized-Bed IQF with Variable Fin-Spacing Evaporator
Variable-pitch fins (denser cold end, looser warm end) extend defrost intervals from 6–8 hours to 18–24 hours. Combined with 150 mm B1-grade polyurethane panels (≥40 kg/m³) and 4:1 ammonia or freon pump circulation, the chamber holds −35 °C with full HACCP drainage.
Result: higher uptime, lower refrigeration OpEx per tonne frozen.
Automation Levels: Manual, Semi-Automatic, and Fully Automatic French Fries Lines
The automation question is rarely answered correctly on the first try. Most first-time buyers either over-automate (buying a fully automatic French fries production line when their throughput and labor cost don’t justify it) or under-automate (saving 25% on CapEx but giving back 40% on OpEx and product consistency within 18 months).
Three-Tier Comparison
| Dimension | Semiautomatico | Mostly Automatic | Fully Automatic |
|---|---|---|---|
| Typical throughput | 100–300 kg/h | 300–1,000 kg/h | 1,000–5,000+ kg/h |
| Operators required | 8–12 | 6–10 | 3–6 (per shift) |
| Control system | Local switches + relay logic | PLC + HMI per machine | Centralized PLC + SCADA, optional MES |
| Output consistency | ±8–12% | ±4–6% | ±2–3% |
| CapEx range | USD 110k–280k | USD 380k–750k | USD 1.1M–5M+ |
| OEE achievable | 55–65% | 70–78% | 82–88% |
| ROI window | 14–24 months | 18–28 months | 24–36 months |
| Best fit | Local QSR supply, low labor cost regions | Regional brand, mixed product runs | Export, retail private label, 24/7 ops |
The Decision Heuristic We Use With Buyers
If your fully-burdened operator cost is below USD 350/month and your target throughput is under 500 kg/h, a semi-automatic French fries production line is almost always the right answer — the labor saving from automation simply doesn’t pay back fast enough.
If your operator cost is USD 600/month or above, or if you’re targeting export markets where pack-weight tolerance and traceability matter, fully automatic is the only configuration that works long-term.
A specific note for buyers in Africa and South Asia: we’ve seen many plants successfully start with a mostly automatic line (auto peeling, cutting, blanching, frying, freezing — but manual sorting and palletizing) and then upgrade two or three modules to fully automatic in years 3–4 once volume justifies it. Our line layouts are designed with this upgrade pathway in mind, so you don’t end up scrapping equipment at the upgrade point.
Why Manufacturers Choose Us for Their French Fries Production Line
A French fries production line is a 10–15 year capital decision. Below are five capabilities that set our engineering and project delivery apart — stated with evidence, not slogans.
1. 15+ Years Field Commissioning, Not Office Engineering
40+ lines delivered across 18 countries including Nigeria, Egypt, Saudi Arabia, Indonesia, Vietnam, Bangladesh, Mexico, and Russia. Every line is commissioned by our own engineers on-site for 4–6 weeks.
Our standard-spec choices (1.5× condenser oversizing for ambient ≥38 °C, multi-fuel burners, voltage-stabilized PLC cabinets) are tuned for real field conditions, not lab benchmarks.
2. Process Engineering Beyond Equipment Supply
Every project includes the raw-material spec packet (variety, dry matter, reducing sugar, storage protocol), SAPP dosing curve, two-stage blanch validation procedure, TPM monitoring schedule, and IQF core-temperature SOP.
These are the parameters that determine whether your fries pass a McDonald’s, Carrefour, or Lulu spec sheet — and they’re rarely in a competitor’s scope.
3. Multi-Fuel Flexibility for Emerging Markets
Our external gas heat exchanger runs on natural gas, LPG, diesel, heavy oil, or methanol without hardware modification. We’ve shipped lines to West Africa running diesel year-round, and to MENA running LPG with seasonal switching to natural gas.
4. Inline Filtration That Triples Oil Life
The dual-redundant coarse filter plus inline fine filter architecture is standard scope on every par-fryer above 500 kg/h. On a 3,000 kg/h line, this single design choice saves USD 180,000–240,000 annually in palm oil — more than the incremental CapEx of the entire filtration package.
5. Upgrade-Path Layout Design
Every layout includes pre-allocated footprint and utility tap-offs for future modules (additional packaging train, optical sorter, higher-capacity fryer, second IQF tunnel).
At the upgrade point, you install into the reserved bay rather than scrapping the original line. This commitment is written into the contract.
Plant Layout and Utility Requirements for a French Fries Production Line
A common and costly mistake at the project-design stage is locking in equipment before finalizing layout, utility loads, and civil tolerances. By installation, workshops may be 15% undersized, steam headers too small, and wastewater pits inadequate. Retrofitting these errors is frequent and expensive.
Workshop Layout Principles We Apply
- One-way material flow: Raw potatoes enter the dirty zone → wet zone (cut/blanch/dry) → hot zone (par-fry) → clean zone (cool/IQF/pack). No backtracking or cross-contamination.
- Clean/dirty zoning: Separate staff uniforms, door entries, and ideally break rooms. Enables BRC and IFS audits to pass first time.
- Overhead utilities: Steam, air, water, and power run above equipment; floor drains pitched 1.5–2% toward collection points.
Utility Load Reference (1,000 kg/h Frozen Line)
For a typical fully automatic 1,000 kg/h frozen French fries production line, plan around these utility loads:
| Utility | Demand | Notes |
|---|---|---|
| Installed electrical | 180–220 kW | 380 V / 50 Hz, 3-phase + N |
| Natural gas | 95–120 m³/h | If using gas-fired par-fryer + steam boiler |
| Process water | 14–18 m³/h | Soft, ≤ 200 ppm hardness |
| Saturated steam | 1.5–2.0 t/h | 0.7–0.8 MPa from a 2 t boiler |
| Compressed air | 1.5–2.0 m³/min | 0.6 MPa, dry, oil-free |
| Refrigeration load | 180–220 kW | For IQF tunnel, ammonia or freon |
| Wastewater | 12–15 m³/h | BOD 1,800–2,400 mg/L, requires pre-treatment |
Scale these roughly linearly for other tiers (a 3,000 kg/h industrial line lands at 350 kW electrical, 280 m³/h gas, 40 m³/h water, 4 t/h steam, with 2,000–2,500 m² footprint and 15–18 operators).
Quality, Food Safety, and Certifications for a French Fries Production Line
Frozen fries are a globally traded commodity, which means your line must be designed not just to produce — but to certify. Buyers in EU retail, US foodservice, GCC supermarkets, and African export markets all gate procurement on documented food-safety compliance.
Certification Stack We Build Into Every Line
A properly specified French fries production line is designed to meet global food safety and regulatory standards:
- HACCP: Mandatory worldwide
- ISO 22000: Quality management system framework
- BRCGS Food Safety Issue 9: Required for UK and most EU private-label retailers
- IFS Food: Required for German, French, and Italian retailers
- FDA 21 CFR 117: US market compliance
- GCC Halal Compliance: Middle East markets
- EAC TR CU 021/2011: Russia, Belarus, Kazakhstan, and EAEU countries
In addition, the production line carries CE marking for European machinery safety and PED 2014/68/EU compliance for pressurized components such as steam peelers, blanchers, and fryer pressure vessels.
Six Critical Quality Control Points (KQCPs)
In our experience, six control points determine whether your final product passes or fails buyer specs:
KQCP-1 Raw potato sugar control. Reducing sugar must stay below 0.4% (target 0.3%) — above this threshold, par-frying produces unacceptable browning regardless of process tuning. We recommend in-line refractometry at receiving plus a 14–21 day temperature-controlled storage program at 7–9 °C.
KQCP-2 Two-stage blanch validation. Polyphenol oxidase activity should test negative on a peroxidase assay after the 90 °C stage. If it doesn’t, color failures will appear after 60–90 days frozen storage.
KQCP-3 SAPP dosing accuracy. 0.3–0.5% w/w in the second blanch tank, monitored by daily titration. Under-dosing causes gray-blue discoloration; over-dosing causes a metallic aftertaste.
KQCP-4 Acrylamide control. Critical for EU market (Regulation 2017/2158). Hold par-frying temperature ≤ 180 °C, control reducing sugar at source, and validate finished-product acrylamide ≤ 500 µg/kg.
KQCP-5 Frying oil TPM (Total Polar Material). Test daily; replace before TPM exceeds 24%. Our inline filtration architecture typically holds TPM at 12–16% for 12–15 days continuous operation.
KQCP-6 IQF core temperature verification. Target ≤ −18 °C at tunnel exit, validated daily with a thermocouple probe inserted into a finished strip.

CapEx, OpEx, and ROI Math for a French Fries Production Line
Below is a transparent investment model for a representative 500 kg/h fully automatic frozen French fries production line, based on real project costs.
CapEx Breakdown
| Articolo | % of Total | Notes |
|---|---|---|
| Process equipment (line) | 60% | What you’ll see on our quotation |
| Civil works & foundations | 12–15% | Depends on greenfield vs. brownfield |
| Utility build-out | 8–10% | Boiler, transformer, refrigeration room |
| Installation & commissioning | 7–9% | Includes our engineers on-site 4–6 weeks |
| Spare parts (Y1) | 4–5% | Belts, bearings, filter elements, seals |
| Operator training | 1–2% | 2–3 weeks, language-specific |
| Contingency | 5–8% | Recommended buffer |
For the 500 kg/h tier, total project CapEx typically lands between USD 580,000 and USD 850,000, with the line equipment itself at USD 380k–520k EXW.
OpEx Structure
Annual OpEx for the same 500 kg/h line operating two 8-hour shifts × 300 days breaks down approximately as:
| OpEx Category | % of Revenue | Notes |
|---|---|---|
| Raw potato | 38–42% | At ~USD 0.30/kg, 50% yield |
| Frying oil | 8–11% | Palm oil, with our filtration ~12–15 day life |
| Energy (gas + electric) | 6–9% | Lower if grid is cheap |
| Direct labor | 4–7% | Highly geography-dependent |
| Packaging materials | 5–7% | Bags, cartons |
| Maintenance & spares | 2–3% | After Y1 |
| Other (water, treatment, QC) | 2–3% |
ROI Illustration
At 500 kg/h × 14 hr/day × 300 days = 2,100 tonnes finished fries/year, at a wholesale price of USD 1.10–1.30/kg (typical export FOB from Asia), revenue runs USD 2.3–2.7 million. EBITDA margin lands in the 22–28% range for a well-run operation, putting payback at 24–32 months including civil works. Pure equipment payback (excluding civil/utility) is often 18–24 months.
These numbers assume you’ve sized the line correctly and your raw potato supply is locked in. If either of those is off, the math changes fast — which is why we always start a project conversation with raw material strategy before equipment.
Buyer’s Checklist: How to Choose the Right French Fries Production Line
After 15+ years and 40+ deliveries, here’s the 10-point checklist we walk every buyer through before signing:
1. Confirm your finished output target — in finished frozen kg/h, not raw potato kg/h. Build in 25% headroom for year 3–4 growth.
2. Lock down your potato supply — variety (Russet Burbank, Innovator, Shepody for fries; not Atlantic — that’s chip-grade), reducing sugar contract spec, storage capacity for 2–3 months buffer.
3. Decide automation level honestly — based on local labor cost, not on aspiration. Over-automation kills more first-time projects than under-automation.
4. Verify utility availability — pipeline gas, grid stability, water hardness, wastewater treatment options. Site visits before equipment ordering, always.
5. Specify your target export markets early — this drives certification, packaging line specs (bag formats, multilingual printing), and IQF design.
6. Audit the supplier’s after-sales footprint — do they have engineers in your region? Local spare parts depot? Remote PLC support? Response time SLA?
7. Insist on FAT before shipment — Factory Acceptance Test with your engineers present, on real potatoes, for a full 8-hour run.
8. Negotiate training scope — minimum 2 weeks on-site post-commissioning, in your operators’ working language.
9. Clarify warranty boundaries — 12 months full warranty is standard; what’s covered, what’s excluded (consumables, electrical components, operator-induced damage).
10. Plan the upgrade path — your line should accept module upgrades (higher-capacity fryer, additional packaging train, optical sorter retrofit) without core re-engineering.

Frequently Asked Questions About French Fries Production Lines
The peeling, washing, and packaging stages overlap by ~70%, but cutting (strip vs. slice), blanching (two-stage vs. single), par-frying (50–140 s vs. 3–3.5 min full fry), and freezing (IQF vs. immediate seasoning) are entirely different. A combined potato chips and frozen French fries processing line is technically possible with shared front-end equipment and switchable cutting/frying modules, but it adds 15–20% CapEx vs. a single-product line.
Total project cost (equipment + civil + utilities + installation) ranges from USD 280k for a 200 kg/h small-scale plant to USD 5M+ for a 3,000 kg/h industrial export facility. Equipment alone is typically 60–65% of total project CapEx.
100 kg/h finished output is the practical floor for a frozen plant. Below this, fixed costs (refrigeration, packaging line, QC lab) don’t amortize favorably. For fresh-cut or vacuum-packed snack fries, 50 kg/h is workable.
Yes — fresh fries simply skip the IQF tunnel and pack into chilled cartons after par-frying. The same line can switch product formats with a 30–45 minute changeover.
Russet Burbank (industry gold standard, US/Canada), Innovator (EU favored, high yield), Shepody (early-season, North America), and Lady Claire or Markies for European processors. Look for 20%+ dry matter and reducing sugar < 0.4%.
Manufacturing 10–14 weeks, sea shipment 4–6 weeks, on-site installation + commissioning + training 8–10 weeks. Total 24–28 weeks contract to commercial production is the realistic window.
For EU: HACCP + BRCGS or IFS + EU 2017/2158 acrylamide compliance + organic certification if applicable. For US: FDA 21 CFR 117 (Preventive Controls) + FSVP for importers + GFSI-recognized scheme (BRCGS, SQF, or FSSC 22000). Halal and kosher are market-specific.
At 14 hr/day × 300 days, producing ~2,100 tonnes/year at USD 1.10–1.30/kg wholesale, EBITDA margin 22–28%, equipment payback typically 18–24 months and total project payback 24–32 months.
Building a French Fries Production Line That Lasts a Decade
A French fries plant is a 10–15 year capital investment. Lines we commissioned in 2010 are still running today because they were designed with the right output, automation, and utility headroom for growth.
Our approach is proven across 40+ projects in Africa, the Middle East, Southeast Asia, and Latin America. Whether it’s a small frozen line for a QSR, a fully automatic private-label line, or a 3,000 kg/h industrial line for export, the principles are the same:
- Optimize peeling, blanching, and par-frying
- Build in upgrade and expansion headroom
- Work with a supplier whose engineers are on-site when needed
We can provide a custom layout, utility load calculation, and ROI model for your market — no obligation, no generic templates, just real numbers based on your conditions.
