Description
The NS-X322 opens macadamia nuts automatically at about 150 kg/h using a 6 kW three-phase drive. Two settings are adjustable on the machine: the opening angle and the opening diameter, so one unit can be set for different nut sizes and different slot depths. It is the production-scale option for processors who sell opened macadamia in volume.

How the NS-X322 opens a nut
Opening is not shelling. A shelling machine loads the shell until it cracks and then separates shell from kernel; an opening machine cuts a controlled slot so the shell can be opened by hand or by a downstream separator with the kernel still whole. That is why the working variables on the NS-X322 are an opening angle and an opening diameter rather than a cracking gap – and why the machine is usually found in plants that sell opened macadamia to retail or to food manufacturers rather than kernel buyers. If you are still deciding between the two approaches, the comparison of shelling and opening machines sets out which one suits which product.
Setting the opening angle and diameter
Both settings are adjustable on the NS-X322, which is what allows one machine to run more than one nut size. Set them in this order, and change one at a time.
| Opening diameter | Locates and holds the nut at the working edge | Nuts feed without jamming and the slot lands in the same place on every nut |
|---|---|---|
| Opening angle | How steeply and how deeply the slot is cut into the shell | The shell opens cleanly at your next process step, with the kernel intact |
| Feed rate | How long each nut stays at the cutting edge | Output holds near 150 kg/h without the machine sounding loaded or discharging part-opened nuts |
Nut size, shell thickness and moisture all move through a season, so a setting is only meaningful next to the condition it was made for. Record the setting and the material condition together – the habit described in our nut processing machine maintenance checklist – and the machine can be returned to a known setting when the crop returns to a known condition.
What to prepare before you order
- Nut size range. The smallest and largest nut you will run, because that range decides how far the opening diameter has to travel.
- Target output. Opened nuts per hour or per day, so the capacity figure can be checked against your shift pattern rather than against a peak.
- The next process step. Hand opening, a separator, or a downstream shelling stage – each one wants a different slot depth.
- Your power supply. The NS-X322 is specified as a 6 kW, 380 V machine. If your site runs a different voltage or frequency, say so in the enquiry: configuration is confirmed in writing before production, and the voltage and power requirements page for export orders explains what to measure at the machine position.
- Destination port. The machine ships in a 2.70 CBM crate at about 570 kg packed, so packing and freight depend on where it is going.
Getting it running and keeping it running
A delivered machine is not a commissioned one. Rotation direction, guarding, a no-load run and calibration on your own nuts are checked in that order, on the day the line is first powered – the sequence is set out in how to inspect and commission a nut processing line. After that, the day-to-day work is small: verify the opening setting against a sample at the start of a shift, keep the working edge clean, and write down what you changed. Those three habits protect the whole-kernel rate more than any single adjustment.
Frequently asked questions about the NS-X322
What is the difference between the NS-X321 and the NS-X322?
The NS-X321 is a compact single unit running at about 50 kg/h for small batches. The NS-X322 is the production machine: about 150 kg/h, a 6 kW three-phase drive, and both the opening angle and the opening diameter can be adjusted.
Can the NS-X322 handle different macadamia sizes?
Yes. The opening diameter is adjustable, so the same NS-X322 can be set for different nut sizes, and the opening angle can be changed to control how deep the slot is cut.
What power supply does the NS-X322 need?
The NS-X322 needs a 6 kW three-phase 380 V supply. Confirm your site voltage when ordering so the drive is built and tested for it.
Does the NS-X322 crack the kernel?
The NS-X322 is an opening machine, so it cuts a slot in the shell rather than crushing it, which protects the kernel. Some loss is unavoidable and we set the machine on your sample so you know the expected whole-kernel rate before ordering.
