macadamia nut opening machine is a specialized cutting unit designed to score macadamia shells before cracking. It handles the hardest shell of any commercial nut. The machine comes in two configurations. The XGKK-10 is a pneumatic mechanical unit. TheTZKK-21 is an electro-pneumatic hybrid with servo control. Both cut a controlled groove around the shell circumference. This makes downstream cracking easier and reduces kernel breakage.
The XGKK-10 processes 50 kg per hour. The XGKK-21 processes 90 kg per hour. Both models use adjustable cutting depth. The XGKK-21 adds programmable cutting angle, cutting depth, and cutting speed through a touchscreen interface. This flexibility lets processors match the cut to different macadamia varieties and shell thicknesses.
Compared with manual slitting, this macadamia nut cutting machine delivers consistent groove depth, higher output, and lower labor costs. It is ideal for macadamia processors, shelling factories, and orchard cooperatives upgrading from hand tools to automated production.
Taizy has supplied nut processing machinery for over 20 years. Equipment is exported to more than 30 countries. Every macadamia nut opening machine is backed by a 12-month warranty with lifetime technical support.

Why Do You Need a Macadamia Nut Opener Before Cracking?
Macadamia shells are the hardest of all commercial nuts. Direct cracking without pre-scoring often shatters the kernel. A macadamia nut opener cuts a controlled groove. This weakens the shell along a set line. The kernel releases more cleanly during cracking.
A macadamia shell cutter also improves throughput in downstream shelling equipment. Cracked nuts separate faster. Kernel recovery rates increase. Whole kernel percentages rise.

8 Core Advantages of Macadamia Nut Opening Machine
Adjustable Cutting Depth
Both models offer adjustable cutting depth to match different shell thicknesses and help reduce kernel damage.
Consistent Shell Scoring
The rotary cutting system creates a controlled groove around the shell, providing more consistent scoring than manual slitting.
50–90 kg/h Capacity
The XGKK-10 processes 50 kg/h, while the XGKK-21 reaches 90 kg/h, supporting higher output with fewer workers.
Reduced Kernel Breakage
The controlled cutting path weakens the shell along a set line, making cracking easier and helping improve whole kernel recovery.
One-Operator Operation
One operator can monitor either model during normal operation, reducing labor compared with manual slitting.
Programmable Servo Control
The XGKK-21 uses servo motors, PLC, and touchscreen control to adjust cutting angle, depth, and speed.
Quick Variety Changeover
The XGKK-21 stores multiple cutting programs, allowing quick setting changes for different macadamia varieties.
Two Models for Different Needs
The XGKK-10 provides a pneumatic mechanical solution at 50 kg/h, while the XGKK-21 offers servo control and 90 kg/h capacity.
How Does the Macadamia Nut Cutting Machine Work?
Both models use a rotary cutting system. Macadamia nuts feed into a positioning station. A cutting disc scores the shell along a set path. The depth is controlled to avoid damaging the kernel.
XGKK-10 Pneumatic Model
The XGKK-10 uses pneumatic cylinders to drive the cutting mechanism. Nuts enter a rotating drum with positioning cups. The cutter head scores each nut as it passes. A mechanical depth stop limits how deep the blade cuts. This model is simple, durable, and easy to maintain. It suits processors with stable production requirements and limited electrical infrastructure.
XGKK-21 Servo Hybrid Model
The XGKK-21 adds servo motors and a PLC with a touchscreen. The dual servo system controls the cutting head position and the drum rotation. Operators can program:
- Cutting angle
- Cutting depth
- Cutting speed
The machine stores multiple programs for different macadamia varieties. Changeover takes minutes instead of mechanical adjustments. The three-phase 380V power supports continuous operation at higher output.
What Macadamia Varieties Can the Machine Handle?
The macadamia nut opening machine accepts standard commercial macadamia sizes. The positioning cups can be adjusted for smaller or larger nuts. Both models work with common varieties including:
- Integra
- A4
- 695
- 344
- Own Choice

What Production Problems Does the Macadamia Shell Cutter Solve?
| Pain Point | Manual Slitting | Macadamia Nut Opening Machine |
|---|---|---|
| Inconsistent groove depth | Variation causes kernel damage or incomplete cracks | Servo-controlled depth stays within ±0.1 mm |
| Slow output | 10–20 kg/h per worker | 50–90 kg/h with one operator |
| High labor cost | Multiple workers needed | Single operator sufficient |
| Kernel breakage | Uncontrolled force shatters kernels | Precise cutting path preserves kernel integrity |
| Difficult variety change | Mechanical adjustments take hours | Touchscreen changeover in minutes (XGKK-21) |
Case Example: Macadamia Processor in Kenya
A macadamia processor in Kenya’s Central Highlands was hand-slitting nuts before shelling. Five workers produced about 80 kg per hour. Groove depth varied widely. Kernel breakage reached 18%.
They installed the XGKK-21 macadamia nut cutting machine. Results after commissioning:
- Output increased from 80 kg/h to 90 kg/h with one operator
- Labor dropped from five workers to one
- Kernel breakage fell from 18% to under 5%
- Whole kernel recovery rose from 70% to 85%
- Changeover between varieties took under 5 minutes
The processor now supplies export-grade whole kernels to European buyers at premium prices.
