Cashew Processing Machine Price Guide
What drives the cost, machine by machine
A buyer’s guide to what actually drives the cost of cashew processing machinery — capacity, automation, build quality and utilities — stage by stage, so you can specify a line before requesting a costed quote.
Cashew processing machine cost is driven by four things: the capacity you are targeting (kg/h of RCN on a Size A basis), the automation level you choose, the build quality of the equipment, and the utilities the line needs — boiler steam, compressed air and power. TTQ quotes per configuration and per destination rather than publishing a price list, because landed cost varies so widely by specification and market that a headline figure misleads more than it helps. This guide sets out what you are specifying at each stage and what makes it cost more — contact us for price.
Cashew processing has moved from labour-intensive manual work to automated lines, and equipment cost follows that spread. What a plant costs depends on four things: the capacity you are targeting, the automation level you choose, the build quality of the equipment, and where it ships from. The sections below set out what you are actually specifying at each stage and what moves the cost — a specification tool, not a price list.
What a complete plant is made of
A complete cashew nut processing plant is a sequence of machines, each doing one job on the way from raw cashew nuts (RCN) to packed kernels: size sorting, steaming, shelling, drying, humidification, peeling, grading, colour sorting, metal detection and packing. Steam for the steaming and drying stages comes from a boiler; peeling and pneumatic transfer need an air compressor. Total investment scales with the throughput you want and how much of the handling between stages is automated.

Stage by stage: what drives the cost
Raw nut size sorting
grades RCN by size so every later stage sees a uniform nut. Vibrating-screen or roller mechanisms from 300–500 kg/h up to 1,800–2,000 kg/h; complete batch sorting lines run 5 to 35 tonnes per batch. What moves the cost: throughput, manual versus automated feeding, dust extraction, and whether the screens are adjustable in service or fixed to one calibration.
Steaming
softens the shell so it cuts without damaging the kernel — 3–4 bar for 20–25 minutes is the typical working point, with each model carrying its own cycle. Batch sizes run 300, 600, 800 and 1,000 kg. What moves the cost: batch size, chamber and steam-distribution design, electric versus boiler-fed heat, and PLC control with automated batch handling. Insulation and heat recovery cost more up front and pay back in fuel.
Shelling
the heart of the plant. Whole-cutting runs 85–90%, with under 5% uncut going back for reprocessing and breakage under 3%. What moves the cost: head or knife count and the capacity that follows from it, size-adaptive blade positioning, pneumatic or hydraulic actuation for consistent cutting force, automated feed and discharge, and sensors that detect uncut nuts and redirect them automatically.
Boiler
300 to 4,000 kg of steam per hour, sized against the dryer, the steaming machine and any humidifier. The same TTQ boiler range fires cashew shell, wood chips or pellets, at 90–95% shell combustion efficiency. What moves the cost: steam output, fire-tube versus water-tube construction, and fuel handling — shell-fired units burn your own processing waste but need shell storage and conveying. Multi-fuel flexibility costs 20–30% more than single-fuel.
Boiler options that add cost
PLC control with touchscreen, automatic water-level and pressure regulation and safety interlocks are the first increment. High-efficiency builds with economisers and air preheaters cost 15–25% more and recover it in fuel within 2–3 years. ASME/CE/ISO certification carries a premium. Automated fuel feeding, ash removal and emission control are the largest single addition — specify them only if your shift pattern justifies removing the manual work.
Borma drying
Stage 08, after shelling — the borma oven takes shelled kernels from the post-steam 9–12% band down to 3–4%, which is what makes the testa brittle enough to peel. Chambers of 0.5, 1, 1.5, 2 and 4.5 tonnes per batch, all on a 13–14 hour cycle. What moves the cost: batch size, fan count and air distribution, insulation quality, and whether temperature and humidity are logged or set by hand.
Humidification
Stage 09, a separate room from the borma dryer — controlled rewetting back up to roughly 5–6% so the testa releases without breaking the kernel. Saturated steam rather than water spray gives uniform uptake without the surface wetting that invites mould. 0.5 to 4.5 tonnes per batch; cycles run 5–6 hours on the smallest chamber and 3–5 hours on the largest. Built on the same chamber platform as the borma dryer at half the connected fan power, which is why the two look alike on a layout drawing. What moves the cost: chamber size, steam-distribution control and automated batch handling. See cashew nut processing for the surface-versus-core moisture gradient TTQ works to.
Peeling
rotating drums with abrasive or rubber linings, compressed air blowing the skin clear. One head gives 120–180 kg/h and four heads 420–480 kg/h, all on the same 5 HP (3.7 kW) drive. Quality machines hit 80–85% white wholes and 80–90% first-pass peel; inferior equipment gives 60–70% white wholes, which is where the money is actually lost. What moves the cost: head count, drum lining, air-circuit design, and automation of feed and recirculation.
Air compressor
sized to the peeling machine plus any other pneumatics running at the same time: one peeling head pairs with 30 HP (22 kW), two with 50 HP (37 kW), three with 75 HP (56 kW) and four with 100 HP (75 kW). What moves the cost: rotary screw units are more efficient for continuous running than reciprocating piston but cost 30–40% more, and inverter versions cost more again while earning it back where the grid fluctuates. Budget for the complete air system — dryer, filters and distribution piping — not the compressor alone.
Classifying
separates kernels into W240, W320, W450 and the broken grades. Roller classify machines run 150–180 kg/h on 12 axes, 210–270 on 18, 280–360 on 24 and 420–540 kg/h on 36; a dedicated broken-kernel sorter adds 150–200 kg/h. What moves the cost: axis count and the throughput it buys, automated grade collection, and dust extraction. Misgrading costs money in both directions.
Colour sorting
cameras and air ejectors removing insect damage, discoloration and foreign material after roller grading. Chute sorters handle 500–1,000 kg/h for compact plants; belt sorters with 18 cameras, 252 channels and 4 chutes run 1–3 t/h for export lines. Effectively mandatory for export quality. What moves the cost: camera count, channel density and throughput — repaid through labour savings and grade consistency.
Metal detection
a food-safety requirement before packing, catching ferrous, non-ferrous and stainless contamination down to 1–2 mm. What moves the cost: detection sensitivity, conveyor width, and whether rejection is automatic or manual. Modest power draw (about 2 HP), stainless build.
Vacuum packing
11.34 kg (25 lb) and 22.68 kg (50 lb) bags at 50–70 packs per hour on a 45-second vacuum cycle with two operators. Double-chamber machines seal one side while the operator loads the other. What moves the cost: single versus double chamber, automated bag feeding, and how heavily the machine is built for continuous running. Note that the kernel sorting line ahead of the packer (1,000–1,500 kg/h) is a separate machine, not part of the packer.
CNSL shell press
screw presses recovering cashew nut shell liquid from the shell, which is around 70% of raw-nut weight and holds 20–25% CNSL. What moves the cost: press throughput matched to your shelling rate, and the materials and seals specified for a caustic liquid. CNSL revenue offsets a meaningful share of fuel cost, but the liquid burns skin and needs proper handling gear and trained operators.
Moisture meters
handheld RCN and kernel probes for buying-in and spot checks, with sample cutting tools for outturn work — the cheapest instruments in the plant and the ones that decide what you pay for raw nuts. In-line continuous monitoring costs considerably more and suits plants running automatic process control.
Plant scale and annual output
| Plant scale | Capacity (kg/h) | Annual production potential |
|---|---|---|
| Small | 300–500 | 1,800–3,000 tons |
| Medium | 800–1,000 | 4,800–6,000 tons |
| Large | 1,500–2,000 | 9,000–12,000 tons |
Equipment is only 55–65% of a project. Installation, electrical work, buildings, utilities and raw-material inventory typically add 40–60% on top of the equipment package.
The small line assumes one peeling machine and no colour sorter; the medium line adds a colour sorter and a second peeler; the large line runs four peelers, a multi-channel sorter, two packing machines and a shell press. Those additions are most of the jump between tiers — capacity alone does not explain it.
What each configuration actually contains
The scale tiers above come from specific equipment lists. Reading down a column tells you what a plant at that scale is actually buying — and reading across shows where the money goes as capacity rises.
| Machine | Small (300–500 kg/h) | Medium (800–1,000 kg/h) | Large (1,500–2,000 kg/h) |
|---|---|---|---|
| Raw nut size sorting machine | Included | Included | Included |
| Stand steaming machine | Included | Included | Included |
| Auto shelling line | Included | Included | Included |
| Boiler | 500 kg/h | 1,500 kg/h | 3,000 kg/h |
| Dryer machine | Included | Included | Included |
| Humidifier | Included | Included | Included |
| Peeling machines | 1 × 120–180 kg/h | 2 units | 4 units |
| Air compressors | 30 HP | 50 HP | 100 HP |
| Kernel classify machine | Included | Included | Included |
| Colour sorter | not fitted | Included | multi-channel |
| Conveyor metal detector | Included | Included | Included |
| Vacuum packing machine | Included | Included | 2 units |
| CNSL shell press | not fitted | not fitted | Included |
The colour sorter, the second and fourth peelers and the shell press are what separate the tiers — capacity alone does not account for the jump.
Operating costs
| Cost category | Small plant (500 kg/h) | Medium plant (1,000 kg/h) | Large plant (2,000 kg/h) |
|---|---|---|---|
| Daily electrical (kWh) | 1,500–2,000 | 3,000–5,000 | 6,000–9,000 |
| Monthly energy cost | $1,200–2,500 | $2,000–8,000 | $4,500–15,000 |
| Labour (workers) | 25–35 | 35–50 | 60–85 |
| Monthly labour cost* | $6,000–14,000 | $8,500–20,000 | $15,000–34,000 |
| Maintenance (annual) | $2,000–4,000 | $6,000–10,000 | $13,000–20,000 |
| Processing cost per kg RCN | $0.35–0.55 | $0.28–0.42 | $0.22–0.35 |
*Labour ranges account for geographic wage variation — from $200–400 per worker per month in some producing countries to $2,000–4,000+ in developed markets.
Energy
motors across shelling, peeling, classifying and conveying total 50–150 HP (40–110 kW) for a complete line; compressors add 30–100 HP (20–75 kW). A 1,000 kg/h plant draws 3,000–5,000 kWh a day plus boiler fuel equivalent to 400–600 kg of coal or 300–450 kg of diesel.
Labour
automation level sets headcount. At 1,000 kg/h: 35–50 workers manual, 20–30 semi-automatic, 10–15 fully automatic focused on quality control, maintenance and supervision. Where wages are low, less automation can give the better return; where they are high, automation pays.
Maintenance and spares
budget 2–3% of equipment value a year for routine work, 5–8% every 3–5 years for major overhauls (bearings, blade refurbishment, component upgrades), and 5–10% as an initial critical-spares inventory. Service contracts typically run 3–5% of equipment value annually.
What moves price beyond capacity
Materials and build
food-grade stainless steel adds roughly 25–35% over mild steel but is what you want on anything touching kernels: peeling, grading, packing. Name-brand motors, bearings, sensors and controls cost more and cut downtime.
Automation level
manual, semi-automatic and fully automatic versions of the same machine can differ by 2–3×. The right choice is set by local labour cost, not by preference.
Technology and features
PLCs with touchscreen recipe management, sensor feedback on temperature, humidity and moisture, variable frequency drives, remote diagnostics and line-integration capability each add to the package. A full PLC system unifying the whole line is the single largest automation increment — and the one that most changes how many operators the plant needs.
Manufacturer and support
established builders charge 15–30% more, which buys engineering experience, consistent quality control, 1–2 year warranty on major components, installation supervision, operator training and a service network that can actually respond.
Origin and shipping
domestic transport runs 2–5% of equipment value; international shipping adds 10–20% depending on distance and sea-versus-air. Import duties range from 0% under trade agreements to 25%+ in protected markets. Compare landed cost — equipment, freight, insurance, duty and clearance — not the ex-works price.
Where equipment is built
India (particularly Maharashtra, Kerala and Tamil Nadu) offers competitive pricing across a large manufacturer base, with quality worth verifying machine by machine. Vietnam has emerged as a serious builder with competitive pricing and a working understanding of modern processing. China spans budget to high quality, so supplier selection carries real weight. Brazil builds mainly for its domestic market and exports some specialised machinery; Turkey supplies European and Middle Eastern buyers.
Financing options
Equipment loans
fixed-rate over 3–7 years with 10–30% down, typically 6–15% annually depending on creditworthiness and lender.
Lease-to-own and operating leases
lease-to-own transfers ownership at term end and costs more in total but preserves cash flow; operating leases are rental without transfer, useful for proving equipment before committing.
Government programmes
many producing countries offer capital subsidies covering 20–40% of equipment cost, interest-rate subvention, accelerated depreciation or tax credits, and export-focused financing. Eligibility usually turns on minimum investment, jobs created or export commitments.
Vendor financing
some manufacturers finance directly: faster approval than a bank, deferred payment until the line is producing, sometimes payments linked to productivity benchmarks.
Choosing a supplier
Technical track record
years in business and units built, customer references you actually call, a factory visit to see quality control, and a trial run on your own raw material where the manufacturer offers it.
Customisation
standard machines do not suit every raw material. Ask whether dimensions, capacities and features can be modified, whether new machines will integrate with equipment you already own, and whether voltage, safety and environmental requirements for your region are handled.
Training and handover
installation supervision, operator training, maintenance training, documentation covering operation and spare parts, and reachable ongoing support. Equipment performance is limited by operator skill more often than by the machine.
Warranty and after-sales
1–2 years on manufacturing defects is standard; wear items such as blades, screens and gaskets are normally excluded, and some warranties cover parts only, not service labour. Check response time, whether spares ship from stock, and whether remote diagnostics are available.
Technology trends and what they cost
Automation and connected control
centralised line control, production analytics, predictive maintenance from sensor data, and batch-level traceability. Adds 15–25% to basic equipment cost.
Energy efficiency
variable frequency drives, heat recovery from boilers and dryers, better insulation, efficient lighting. Adds 8–12% to equipment cost and cuts operating expense 15–30%.
Food safety and quality
sanitary design that cleans down properly, traceability from raw material to finished goods, X-ray and multi-spectral inspection catching defects a colour sorter misses, and modified-atmosphere packing extending shelf life beyond vacuum.
Return on investment
Processing margin is the gap between RCN cost and kernel selling price, less processing cost — typically $2–4 per kg of raw nuts processed. Four things move it: raw-material quality (better RCN yields more kernel and more wholes), processing efficiency (whole-kernel percentage is what earns the premium), market conditions (kernel prices swing seasonally), and product mix (white wholes earn far more than brokens or scorched).
Utilisation matters as much as margin. A plant running one 8-hour shift uses a third of what the same equipment could produce on three shifts, and fixed costs — depreciation, rent, supervision — spread across that smaller volume. Higher utilisation needs reliable RCN supply, steady demand and maintenance that prevents extended downtime. Note that a full plant cannot run three shifts; the shelling line can. See cashew processing plant for how that constrains a realistic annual figure.
Payback examples circulating for cashew plants routinely assume 16 hours a day for 300 days and arrive at a payback measured in months. That contradicts the per-8-hour-shift basis used across this site, and it ignores working capital and production ramp-up. Treat payback as a project calculation, not a rule of thumb — TTQ will model it against your actual shift pattern and RCN cost.
Nine things worth getting right before you buy
Research the market first
raw-material availability, RCN price trends and finished-product demand in the markets you intend to sell into, before any equipment commitment.
Size the capacity honestly
over-investing in capacity you cannot feed strains finances and depresses return; under-sizing caps growth and loses customers you already have.
Prioritise quality over headline price
cheap equipment gets expensive through poor whole-kernel recovery, frequent breakdowns and a short service life.
Buy a system, not a pile of machines
capacities must match across stages and automation levels should be consistent, or the slowest stage sets the plant rate.
Budget for working capital
equipment is 55–65% of total project cost. Installation, buildings, utilities, RCN inventory and initial operating expenses are the rest.
Treat the supplier as a long-term partner
you will need training, technical assistance and spares from them for a decade, not just a delivery.
Invest in training
machine performance is limited by operator skill more often than by the equipment. Allocate real time and budget to it.
Run preventive maintenance
scheduled work extends equipment life substantially and costs far less than the breakdowns it prevents.
Measure and optimise
track production metrics, quality parameters and cost per kg. You cannot improve whole-kernel recovery you are not measuring.

The process, drawn
Plant scale and what actually separates the tiers
Capacity alone does not explain the jump between plant sizes. The additions do.
Equipment is only 55–65% of a project. Installation, electrical work, buildings, utilities and raw-material inventory typically add 40–60% on top of the equipment package.
Two shelling families — compare within one, never across
Head machines and knife machines are separate ranges, not points on one scale. Reading a head-line capacity against a knife-line capacity is how "16 Head" ends up quoted at 700 kg/h.
- 4 Head line ~140 kg/h
- 10 Head line 350 kg/h
- 16 Head line 560 kg/h
- 2 × 10 Head line 700 kg/h
- 4-knife machine 230 kg/h
- 10-knife machine 400–500 kg/h
- 16-knife line 700 kg/h
- 4 × 10-knife line 1,000–1,200 kg/h
All capacities are Size A input, per 8-hour shift; capacity varies with raw-nut size. "16 Head" is 560 kg/h always. 700 kg/h belongs to the 16-knife line or the 2 × 10 Head line. 1,000–1,200 kg/h comes only from the 4 × 10-knife line.
