Cashew Processing Equipment in Tanzania: Buyers Guide

Tanzania has 57 registered cashew processing factories, but only 36 run. The country produced 528,260 tonnes of raw cashew in 2024/25 and processed just 118,262 tonnes at home, exporting the rest raw to Vietnam and India. That gap is why new lines are being specced, and this guide walks a Tanzanian processor through buying one.

What a full cashew line actually contains

Buyers who treat a cashew plant as a single purchase order tend to overpay and under-spec. A processing line is six distinct stages, each a separate equipment decision with its own vendors, its own failure modes, and its own effect on kernel grade. Get the sequence and the sizing right before you ask anyone for a quote.

Steam cooking and humidification. Raw nuts are conditioned with saturated steam to soften the shell and loosen the kernel. This is where outturn (whole-kernel recovery) is won or lost. Boiler capacity, steam dryness, and dwell time all matter, and the cooker has to be matched to your throughput so you are not steaming in inefficient small batches.

Shelling and cutting. Mechanical shellers crack the conditioned nut and separate kernel from shell, rated in nuts per minute per machine. Calibration to nut size is the single biggest driver of whole-kernel yield. Most modern lines run banks of automatic cutters fed by a size grader, because uncalibrated feed shatters kernels and pushes you into the lower splits-and-pieces grades that fetch less at auction.

Drying (borma). Shelled kernels go into a borma dryer to cut moisture and make the testa (the inner skin) brittle enough to peel. It is usually hot-air, tray or tunnel, and energy cost here is a real line-item, which is why cashew nut shell liquid (CNSL) recovery to fire the dryers is increasingly part of the spec.

Peeling. The dried testa comes off through vacuum or pneumatic peelers plus hand finishing. No machine peels at 100% without breakage, so the realistic spec is a peeler that does the bulk and a finishing station for the rest. Buyers chasing a “fully automatic, zero labour” peeling claim usually get sold a fantasy.

Grading and sorting. Kernels are graded by size, colour, and wholeness, increasingly on electronic colour sorters with camera arrays. This stage sets your saleable grade mix (W180, W210, W240, W320, splits, pieces), and grade mix is what your buyer pays for, so the sorter is not the place to cut the budget.

Vacuum or MAP packing. Finished kernels are packed under vacuum or modified-atmosphere (MAP) with a carbon dioxide flush, usually in tins or laminated pouches, to hit the shelf life European and Gulf buyers demand. The packing line is also where most TBS and export-certification compliance is checked, so it has to be food-grade from the start.

How to spec the line before you ask for a quote

The mistake that wastes the most money is sending vendors a vague “we want a cashew plant” enquiry and letting each one size it differently, so the quotes never compare. Pin down five numbers first.

Throughput. State your target in tonnes of raw cashew per day, not per year, and be honest about your raw-nut supply. The 36 operational factories share an installed capacity around 103,000 tonnes a year, so the typical Tanzanian plant is mid-sized, not a 50,000-tonne giant. Size for the nuts you can actually secure at auction, not for a brochure.

Target grade mix. Decide whether you are selling premium whole-kernel grades into Europe and the Gulf or volume splits and pieces into snack manufacturers. That decision drives how much you spend on calibration, peeling gentleness, and colour sorting.

Degree of automation. Fully automatic lines cut labour but cost far more and break the wrong way in a power-unstable environment. Many Tanzanian processors run semi-automatic shelling with manual peeling finishing, because labour is available and downtime on an over-automated line is expensive. The right answer is the one that fits your wage bill and your grid reliability.

Energy plan. Decide up front whether you will recover cashew nut shell liquid to fire your dryers and boilers. It changes the equipment list and the running cost, and it is far cheaper to design in than to retrofit.

Power and civils. Confirm your connection, standby generation, and building footprint before ordering. A line that arrives before the slab is poured or the transformer is sized just sits in a container accruing demurrage.

The market dynamics that shape the purchase

Two policy mechanics shape every cashew-equipment decision in Tanzania, and both favour a processor who plans around them.

The first is the raw-cashew export levy. Raw nuts attract a levy of 15% of FOB value or USD 160 per tonne, whichever is higher, while processed kernels are exempt, according to the FAO’s analysis of incentives in Tanzania’s cashew sector. The structure is a deliberate tilt toward local value addition: process the nut at home and you keep the margin the levy would otherwise take. It is the number to put in front of your bank when you finance a line.

The second is the capital-goods incentive. Through a Tanzania Investment Centre certificate of incentives, cashew processing investors can import shelling, cutting, drying, peeling, grading, and packing machinery with VAT and import-duty relief on capital goods, per the TIC procedures portal. Build the certificate into your timeline before you ship, because clearing the equipment without it means paying tax you did not need to pay.

There is friction too. Processors have flagged a domestic processing levy of around TZS 2,280 per kilogram as a cost that eats into value-addition margins, a point raised by John Nkundwanabake of the Tanzania Cashewnut Processors Association in reporting by Milling Middle East & Africa. That is a reason to model unit economics properly and spec equipment that hits a high enough whole-kernel grade to absorb the levy, not a reason to wait.

On payment, cashew processors sit on the export-receipt side of the foreign-exchange equation, which helps. The Bank of Tanzania moved the shilling to a floating regime in November 2024 under its IMF program, and the TZS then appreciated roughly 9.5% against the dollar over the following year, easing the periodic dollar tightness importers planned around in 2023. For a line above USD 200,000, the confirmed letter of credit is the default instrument, opened through a bank such as CRDB or NMB and confirmed by a European or Gulf bank for larger tickets. A common structure is 10 to 30% advance, 60 to 70% against documents, and 10% retention after commissioning. Align your milestones to the harvest-receipt calendar, not the calendar year.

Where the buyers and the clusters are

The centre of gravity is the Mtwara and Lindi cashew belt in the south, with Ruvuma, Pwani, Singida, Katavi, and Dar es Salaam holding the rest of the 57 factories. The flagship is the Maranje cashew industrial park in Nanyamba District, Mtwara, a roughly TZS 300 billion build on about 1,575.5 acres slated to house around 30 factories, developed with Arise IIP and overseen by the Cashewnut Board of Tanzania, per TanzaniaInvest.

The named buyers a line supplier quotes to are the board, the cooperative unions, and the private processors. The Cashewnut Board of Tanzania (CBT) oversees Maranje and the auction system. Cooperative unions such as Tanecu in Tandahimba and Newala and Tamcu in Tunduru are building their own factories, and investors taking plots inside Maranje buy plant-by-plant. CBT Director General Francis Alfred has put the trajectory on record, telling reporters the government forecasts 700,000 tonnes by the 2025/26 season and one million tonnes by 2030/31, so the processing deficit is widening, not closing.

Dying conventional channels for cashew equipment suppliers

The old ways European and Indian cashew-line builders reached these buyers are losing their return.

The Dar es Salaam International Trade Fair (Saba Saba) each July is still a national fixture, but for industrial food-processing OEMs it has drifted toward consumer goods and SME exhibitors. CBT, the cooperative unions, and the larger private processors rarely walk the floor looking for a shelling line. A fully loaded stand, once you count fit-out, freight, travel, and follow-up, routinely costs USD 400 to 900 per qualified lead with conversion well under 5%. Regional agritech and food-processing expos add reach but produce introductions, not pipeline.

A Dar-based field representative with cashew-sector knowledge runs USD 5,500 to 11,000 a month all-in once you add housing, work permit, and vehicle. At three to six qualified leads a month, that is USD 900 to 3,700 per qualified lead, and the economics only work above several million euros of annual Tanzanian revenue. Distributor and trading-house lock-in is the other drag: the legacy houses take 15 to 30% margin and rarely run active outbound, which leaves specialist cashew-line builders invisible in catalogues while buyers increasingly want direct engineering contact for grade-yield reasons. Print trade-magazine advertising no longer reaches procurement managers who now find vendors through TANePS notifications, peer engineers on LinkedIn, and English-language search.

FAQ

Who are the cashew processing equipment suppliers selling into Tanzania?

The line-equipment vendors are mostly Italian (Oltremare and similar food-processing specialists) and Indian (firms such as JJ Engineers building shellers, peelers, and graders), usually working through a Tanzanian agent for installation and spares. Buyers spec the line, then run a comparable quote across two or three of them.

How much does a cashew processing line cost in Tanzania?

It depends entirely on throughput, grade target, and automation, so any single figure is misleading. Spec your tonnes per day, grade mix, and energy plan first, then run comparable quotes. The bigger savings come from the TIC capital-goods VAT and duty relief and from avoiding the raw-export levy, not from shaving the machine price.

Why process cashew in Tanzania instead of exporting raw?

Raw nuts carry an export levy of 15% of FOB or USD 160 per tonne, while processed kernels are exempt. With 528,260 tonnes produced in 2024/25 and only 118,262 processed locally, the margin left on the table by raw export is the core business case for installing a line.

How do Tanzanian cashew processors pay foreign equipment suppliers?

Through confirmed letters of credit for tickets above USD 200,000, opened at banks like CRDB or NMB and confirmed by a European or Gulf bank for larger orders. A common structure is 10 to 30% advance, 60 to 70% against documents, and 10% retention after commissioning, aligned to the harvest-receipt season.

What is the difference between buying a full line and buying shelling and peeling machines?

A full line is the whole sequence from steam cooking through vacuum packing, integrated as one throughput-matched system. Buying individual shelling or peeling machines suits an existing plant adding capacity. New entrants almost always want the integrated line so the stages are sized to each other and the grade yield holds.
