The Pistachio Shelling Machine is a compact, all-in-one nut processing system engineered to remove pistachio shells at high volume while protecting the kernel inside. It integrates feeding, lifting, size sorting, shelling, and kernel–shell separation in a single stainless-steel line — designed for nut processors, roasters, snack manufacturers, and wholesale packing plants that demand consistent output with minimal labor.
Simply feed the pistachios into the hopper. The machine automatically lifts, pre-sorts by size, cracks the shell, and discharges the shelled kernels and empty shells from separate outlets. Nuts that did not fully crack are recycled back into the shelling chamber automatically, so virtually every nut is processed without manual sorting.
As an experienced pistachio shelling machine manufacturer, we tune every line to the moisture level and shell hardness of your local pistachio variety before shipment.
One machine replaces multiple manual stations — upper hopper → bucket elevator → vibrating sorting screen → gap-adjustable shelling rollers → winnowing separation.
Hulls/shells and whole kernels exit through independent outlets. The winnowing section blows light shells and dust out one side while heavier kernels fall through to the other, so the output arrives at your grading, roasting, or packaging station clean and ready-to-use — no extra manual winnowing required.
This line is designed for businesses that need to move from hand-cracking to a hygienic, repeatable process. The three most common production setups we ship to are:
For factories and packing houses buying in-shell pistachios in bulk and selling shelled kernels by the kilogram, this machine is the heart of the line. It runs continuously through a full shift, sorting nuts by size before cracking so that large and small kernels are not over-crushed. The automatic recycling loop means unshelled nuts are never discarded — they go back through the rollers until the shell is open. One operator replaces a whole team of hand-crackers, standardizes kernel appearance, and removes the hygiene risk of manual shelling on the packing floor.
Roasted, salted, or flavored pistachio kernels are a high-value ingredient in trail mix, baking toppings, ice cream, pistachio oil, butter, and flour. Feeding the line with in-shell nuts and selling shelled output lets you buy raw material at the in-shell price point while selling at the kernel price point — improving gross margin per ton. The winnowing section also removes light shells and dust, delivering a cleaner feedstock to your roaster, press, or mill and reducing filter and sieve changes.
Shelling on-site at origin cuts shipping weight by roughly 40–50% (shells are heavy and low-value), so cooperatives and regional processing hubs can export or distribute kernels instead of whole nuts, capturing more of the supply-chain margin locally. With an MOQ of just 1 set and a compact 3.7 m footprint, this is also a practical entry point for traders testing a new nut-processing category, or for small factories adding pistachio processing alongside almond, walnut, or hazelnut lines. Voltage, plug, and screen mesh can be customized for your country before shipment.

Q1: What is the hourly capacity of this pistachio shelling machine?
A: Capacity depends on the pistachio variety, moisture content, and nut size. The standard 2.6 kW model is engineered for continuous industrial shelling; please send us a sample photo and your target output (kg/h), and our engineer will confirm the exact configuration and recommend the matching motor.
Q2: Will it crack small or soft-shell pistachio varieties?
A: The roller gap is adjustable and the sorting screen can be changed. For non-standard varieties (very small, very oily, or high-moisture nuts), we recommend sending a 1–2 kg sample so we can test the gap and tune the machine before shipment.
Q3: What voltage do you support?
A: The standard machine is wired for 380V / 50Hz / 3-phase. We can re-wire to 220V, 415V, 440V, or 60Hz and fit your country's plug standard at no extra charge — just tell us your local power supply when ordering.
Q4: How do I clean and maintain the machine?
A: The contact surfaces are stainless steel and can be brushed or wiped down between batches. The main wear parts are the shelling rollers and the vibrating screen mesh; both are bolted in place and can be replaced in under an hour with basic tools. We supply a spare parts list and a video guide with every order.
Q5: Does it really separate shells from kernels automatically?
A: Yes. After cracking, the mix passes through a winnowing section that blows the lighter shells and hulls out of one outlet, while the heavier kernels fall through to a second outlet. Unshelled nuts are automatically recycled back into the shelling chamber.
Q6: What is the MOQ and delivery time?
A: MOQ is 1 set. Standard models are usually ready to ship within 15–25 working days after deposit; customized configurations take longer. The machine is packed in a fumigated export wooden case suitable for 20GP / 40HQ container loading.
Q7: Do you provide installation and after-sales support?
A: Yes. Every order includes a full English operation manual, a video installation guide, and remote support from our engineer via email, WhatsApp, or WeChat. On-site installation is available on request for larger lines.
