From idea to export-grade kernels

The whole build, in the order you actually meet it: deciding whether to enter at all, proving the raw material and the market, sizing the money, designing the line, buying the machines, passing the inspections, and surviving the first season.

How this guide handles figures

Two KOR figures, never mixed

Quality-check KOR is a laboratory cutting test in pounds per 80 kg bag, used to price a lot. Production KOR is kg of packed saleable kernel per 100 kg of RCN — 22–24%. A 48 lb test is about 27% laboratory outturn; a plan built on it overstates revenue by 10–15%.

One grade split: 75/25

Packed wholes to brokens. It sits inside every published range — 55–85% depending on method and management, 65% treated as satisfactory, a mechanised line at 75–90% — and matches what a peer-reviewed appraisal actually commits to.

Conversion cost is a range

Not a number. The axis is automation crossed with wage level: about US$155/t of RCN semi-automatic at Asian wage levels, US$490–580/t manual at African ones. Both stacks close; they describe different plants. Packaging and export logistics sit outside both.

Gaps are declared, not filled

Where the published record has no figure — cashew-specific effluent limits, a KOR decline curve for storage, a first-season yield trajectory — the chapters say so rather than inventing one. Where a number is derived, the arithmetic is shown.

Part I

The Decision

What the business actually is, whether it suits you, and the honest alternatives to building.

  1. 1What business you are actually enteringOn the site How to Start a Cashew Processing Business: Step Guide
  2. 2The reality checkOn the site Cashew Nut Processing Plant Cost: Capex & Opex Guide
  3. 3Choosing your business modelMost processors build the merchant model without ever deciding to — buying RCN, shelling it and selling kernel on their own account, which takes the whole spread and the whole risk. Toll processing removes almost all the working capital and price risk in exchange for the spread. The integrated farm-to-retail plan does not fail in year one; it fails in year two, when four cash cycles collide.

Feasibility

Raw material, market, scale, technology and site — the five studies that come before money.

  2. 6Market feasibility: who will buy your kernelsOn the site Where to Find Real Cashew Trade Data and Price Benchmarks

  4. 8The technology decisionOn the site Automatic vs Manual Cashew Cutting: Which to Choose
  5. 9Site selectionNo site wins on all four of raw material, port, power and labour. Rank raw material first — RCN is 64–90% of your cost and access to it is a documented cause of plant failure. Port distance is a freight cost you can calculate; power quality is a downtime risk you cannot; labour is the constraint that arrives in year two.

The Numbers

Capex, working capital, opex per tonne, revenue build and the full financial model.

  1. 11CAPEX architectureOn the site Cashew Nut Processing Plant Cost: Capex & Opex Guide
  2. 12Working capital: the line that decides survivalA cashew plant runs about 300 days a year but the harvest lasts three to four months, so a single-origin processor must buy and carry most of a year's raw material at once. Expect working capital of roughly 1.5–4× your fixed-asset cost — the standard bank templates, built on 30-day stock assumptions, understate it by about the cost of the factory.

The Process

The eight stages, the yield science behind them, and where kernel is actually lost.

  2. 19The yield scienceOn the site Optimising Yield in Cashew Processing: WKR Levers
  3. 20Material and energy balanceThe published cashew material balance does not close — sources put shell at anywhere from 50% to 70% of the nut, a twenty-point spread. Build outward from the number you trust, production KOR at 22–24% saleable packed kernel, and label every other fraction as derived by difference with its measurement point stated.

Designing the Factory

Line sizing and balancing, building layout, utilities, storage and designed-in food safety.

  1. 22Line sizing and balancingSize every stage backwards from saleable kernel tonnage, not forwards from raw-nut intake. After shelling you are handling roughly a quarter of the mass, so the kernel side of a 10 t/day plant runs at about 144 kg/h against 625 kg/h at intake. Grading and peeling are the structural bottlenecks; calibration and packing are almost always over-bought.

Procurement

Specifying equipment, evaluating suppliers, contracting, and acceptance on commissioning.

  2. 29Specifying what you needOn the site The Cashew Processing Equipment Buyer's Guide
  3. 30Evaluating equipment and suppliersOn the site How to Evaluate Cashew Machinery Vendors: A Buyer Framework
  4. 31Contracting, payment and importFull payment before delivery is described in the sector's own literature as a challenge to be solved, not a market norm — and structures of 40% and 70% down are both on record. Hold 10–15% as retention against an acceptance test run on your own nuts, and prefer FCA over FOB for containerised machinery, because FOB leaves you carrying risk through a period you cannot witness.

Compliance

The licensing stack, food safety systems, certification sequencing and export documentation.

  1. 33The licensing stackExpect nine to fifteen separate authorities before your first container leaves. The names differ by country; the functions barely differ at all. Three approvals sit on the critical path before a foundation is poured — land and zoning, environmental consent, and building plan approval — and the environmental consent is the only one whose answer can be 'not here'.

  4. 41Commissioning and the first seasonPlan the first season one to two points of KOR below your tested figure, peeling at 70–80% rather than the specified 80–90%, and year-two utilisation at or under 50% without a committed RCN buying facility. Calibrate the line to your buyer's written specification, not the supplier's demonstration — they are not the same standard.

Part IX

Operating Well

The KPI system, quality in practice, buying RCN, selling kernels, maintenance and risk.

  1. 43The KPI systemFive metrics determine whether a cashew plant makes money: packed wholes, production KOR, capacity utilisation, RCN cost per kg of saleable kernel, and conversion cost per tonne of RCN. Everything else diagnoses why one of those five moved. A point of production KOR is worth roughly 27 times a point of whole-kernel percentage — chase yield before grade.
  2. 44Quality management in practiceOn the site Cashew Plant Audit, Inspection & Capacity Calibration
  3. 45RCN procurement operationsDo not buy on a market view. Derive a maximum landed RCN price from kernel you have already sold: revenue, less conversion cost at 1:1 against RCN tonnage, less your target margin, divided by the tonnes you need. Twenty dollars of conversion cost is twenty dollars of buying power, one for one — which is why it is the only one of the five profit drivers you set yourself.
  4. 46SellingOn the site Cashew Trade Finance, INCOTERMS, and Investment: A Practical Guide
  5. 47Maintenance and reliabilityOn the site Spare Parts, Maintenance & After-Sales Service for Cashew Machinery
  6. 48Risk and insuranceSix named risks dominate cashew processing — RCN supply and cost, traceability, price volatility, currency, policy instability and labour scarcity — with power, fire, quality claims and counterparty default close behind. Stock throughput cover is the right insurance structure, but it explicitly excludes business interruption, and a standard 12-month indemnity period pays for the wrong ten months in a seasonal business.
Part X

Growing

Debottlenecking what you have before spending, then expansion and integration.

  1. 49Debottlenecking and optimisationMeasure throughput at every stage across a full week and find the stage with product queued in front and idle capacity behind. Expect two answers that are not machines — labour availability and raw material. Rank yield projects by the arithmetic: a production KOR point is worth about US$68 per tonne of RCN against about US$2.53 for a whole-kernel point.
