Cashew Basics 7
What cashews are — nut, kernel, shell and skin — and why they are processed.
Are Cashew Nuts Good For You? Benefits & Nutrition
Yes, in moderation. Cashews provide protein, healthy fats and minerals like magnesium, copper and zinc, but they are calorie-dense and a common tree-nut allergen.
Boiled Cashews: Why Cashews Are Boiled or Steamed
Cashews are boiled or steamed before shelling to soften the shell and neutralise caustic CNSL, making them safe to handle and easier to cut without breaking the kernel.
Cashew Husk & Testa: The Red Skin on Cashew Kernels
The cashew testa is the thin red-brown skin clinging to the kernel after shelling; removed by peeling to give clean white kernels, it is rich in tannins and antioxidants.
Cashew In Shell: What It Means & Why It's Processed
Raw cashews in shell can't be eaten — the shell holds caustic CNSL. The nut must be steamed or roasted to neutralise it before shelling, which is why cashews are sold shelled.
Cashew Kernels: Grades, Forms, Nutrition & From Shell
The cashew kernel is the edible, ivory-white seed recovered after shelling and peeling a raw cashew nut; it is graded by size, colour and wholeness.
Cashew Nuts: What They Are, Types, Uses & Nutrition
A cashew nut is the seed of the tree Anacardium occidentale, growing beneath the cashew apple and sold raw in-shell (RCN) or as a processed white kernel.
Cashew Shell: Structure, CNSL Content & Uses
The cashew shell is the hard outer casing of the raw nut, whose honeycomb layer holds caustic CNSL at roughly 25–35% of its weight — now used as fuel and a CNSL source.
Grading & Pricing 11
Grade charts, outturn, HS codes and what kernels actually sell for.
AFI Specifications for Cashew Kernels: Grades & Limits
The AFI standard defines cashew kernel quality for North American trade: grade count-per-lb ranges, colour, defect allowances, maximum 5% moisture and packaging.
Cashew Classification: How Kernel Grades Are Coded
Cashew classification sorts kernels along three axes — colour, size (count per lb) and wholeness — into coded grades (W, SW, DW, splits, pieces) set by AFI, BIS and CEPC standards.
Cashew Grades: The Complete Kernel Grade Chart (W180–W500)
Cashew kernels are graded by colour, size (count per lb) and wholeness: white wholes W180–W500, scorched and dessert grades, and broken splits, butts and pieces.
Cashew Kernels HS Code (0801.32) & RCN Codes
Shelled cashew kernels are classified under HS 0801.32 and raw cashew nuts in shell under 0801.31; national tariff lines add further digits, so duty varies by country.
Cashew Kernels Price Per KG: By Grade, Wholesale & Retail
Cashew kernel prices per kg are set mainly by grade — larger whole grades (W180, W240) cost more than smaller wholes (W320, W450) and far more than broken pieces.
Cashew Nut Kernel Insights: Quality, Grades & Market
A curated hub to cashew kernels — how quality and yield are measured, how grades and prices work, and what moves the market, with links to the detailed pages.
Cashew Outturn (KOR) Calculation Formula + Live Calculator
Outturn (KOR) is the pounds of usable kernel per 80 kg bag of raw cashew — the key metric for pricing RCN. KOR ≈ good kernel grams (per 1 kg sample) × 0.176.
Cashew W320: Meaning, Size, Count per Lb & Uses
W320 is a white whole cashew grade of about 300–320 kernels per lb — the world's most-traded, benchmark grade, balancing quality and price.
CNSL Price & Market (Cashew Nut Shell Liquid)
CNSL (cashew nut shell liquid) is a phenolic bio-oil used in coatings, friction materials and resins — a real revenue line from shell waste. What sets its price.
Raw Cashew Nut to Kernel Ratio: How Much Kernel per KG
The raw cashew nut to kernel ratio is about 22–24% by weight — roughly 4 kg of raw in-shell nuts yields about 1 kg of kernels (a ~4:1 ratio).
W240 Cashew: Size, Count per Lb & Price Premium Explained
W240 is a larger, premium white whole cashew grade of about 220–240 kernels per lb, trading at a premium over the benchmark W320.
Process Guides 17
Step-by-step through boiling, cutting, roasting, grading and packing.
Automatic vs Manual Cashew Cutting: Which to Choose
Manual/semi-auto cutting gives the highest whole-kernel recovery at low capex but is labour-heavy; automatic lines give high throughput and low labour but need calibrated feed. Many plants run a hybrid.
Cashew Before Harvest: Flowering, Maturity & Readiness
Before harvest, a cashew tree flowers, sets fruit, and grows the nut and apple to maturity — when the apple colours and the grey nut detaches and drops, ready to be collected.
Cashew Boiling Process: Steam Conditioning Explained
Cashew boiling (steam conditioning) makes the shell brittle and neutralises its CNSL before cutting, protecting whole-kernel recovery. A steaming cycle runs ~30–45 minutes.
Cashew Manufacturing Process: Every Stage Explained
The cashew manufacturing process runs raw nut to packed kernel: cleaning, sizing, steaming, cutting, scooping, drying, peeling, grading and packing — at ~22–24% kernel outturn.
Cashew Nut Cutting Time: Throughput & What Affects It
Cutting throughput runs from ~10–15 kg RCN per worker per day by hand to hundreds of kg/hour on semi-automatic lines and up to ~1,000 kg/hr on automatic lines — but whole-kernel yield, not speed, is the real KPI.
Cashew Nut Shelling Machine Design & Engineering
Cashew shelling machines split the shell without damaging the kernel using paired shaped blades matched to graded nut size; design centres on blade profile, calibration and gap adjustment.
Cashew Packing & Packaging: Vacuum, Tins & Export
Cashews are exported in vacuum/nitrogen-flushed tins — the 11.34 kg (25 lb) and 22.68 kg (50 lb) sizes, usually two per carton — plus retail pouches, at ~5% moisture.
Cashew Plant Training, Installation & Maintenance
After purchase: installation and commissioning, trial runs and calibration, operator and maintenance training, then a preventive-maintenance programme and spare-parts supply.
Cashew Processing Machine & Turnkey Machinery
A cashew processing machine line turns raw nuts into clean, graded kernels through a fixed sequence — size sorting, steam conditioning, cutting and shelling, drying, peeling, grading, and packing. CASHEW TECH supplies each stage individually or as a full turnkey line sized from 2 to 50 tons of raw nuts per day.
Cashew Season: Harvest Calendar by Country & Region
Cashew harvest runs at different times by region: India and West Africa ~Feb–May, Vietnam ~Feb–June, East Africa ~Oct–Jan, Brazil later in the year — keeping global supply near year-round.
Cashew Shell Liquid (CNSL) Extraction Process Explained
CNSL is extracted from cashew shells by three routes — hot-oil-bath roasting, mechanical expeller pressing, and solvent extraction — with natural CNSL heat-converted to technical cardanol.
Choosing a Cashew Nut Grading Machine: Buyer Guide
Cashew grading covers two jobs: size grading (rotary/sieve sorters into W-grades) and quality/colour sorting (an optional optical sorter). Match the machine to your bottleneck, then check capacity, accuracy and support.
Choosing Your First Cashew Cutting Machine: Full Guide
A first buyer must settle four things: target capacity (kg RCN/day), manual/semi-auto vs automatic, number of cutting heads, and budget including blades and spares.
How to Roast Cashews: Drum, Oil-Bath & Oven Methods
The three industrial cashew roasting methods are rotary drum (dry), hot-oil bath (in CNSL) and continuous oven roasting — typically 180–200°C, distinct from steaming or boiling.
Optimising Yield in Cashew Processing: WKR Levers
Whole-kernel outturn is set by controllable stages: buy good RCN, calibrate and size, condition (steam) correctly, tune cutting, dry gently, and humidify before peeling — small gains compound.
Setting Up a HACCP-Certified Cashew Processing Plant
HACCP certification needs a documented food-safety system: hazard analysis, critical control points (moisture/drying, roasting, metal detection, packing), prerequisite programmes (GMP/SSOP), and clean/dirty zoning.
Setting Up an Ultra-Modern Cashew Processing Unit
An ultra-modern cashew unit chains automated stages — calibration, steam conditioning, automatic cutting, borma drying, peeling, grading and vacuum/N₂ packing — under a central control panel, delivered turnkey.

Cashew Nut Processing Plant Cost: Capex & Opex Guide
A cashew plant's cost splits into one-time capex (machinery, electricals, civil, installation) and recurring opex (labour, power, fuel, RCN working capital) — and raw-nut working capital is often the biggest recurring outlay.
Cashew Processing Labour Requirement & How Automation Reduces It
Cashew processing is one of the most labour-intensive food industries, and the labour is not spread evenly — cutting/shelling and peeling dominate the headcount, while steaming, drying and packing need far fewer people. Automating cutting, peeling, sorting and conveying is what cuts the headcount and the cost.
Financing, Grants & Subsidy for Cashew Processing
How to fund a cashew processing plant — bank loans, development finance and government subsidy for the machinery and the working capital to buy the crop.
How to Start a Cashew Processing Business: Step Guide
Start a cashew business in seven steps: study the market, write a plan/DPR, secure a site, choose machinery and capacity, get licences and food-safety certification, secure RCN and working capital, then install, train and launch.
Solar Power for a Cashew Processing Factory: A Balanced Guide
Solar PV can cover much of a cashew factory's daytime electrical load — cutting, peeling, grading, conveying, lighting — but not its heat (boiler steam and drying), which is far cheaper from cashew-shell biomass. For most factories the honest answer is a hybrid, not solar alone.
