The pistachio slitting machine is a specialized nut processing machine designed for automatic opening of closed-shell pistachios. By precisely cutting the shell seam without damaging the kernel, this machine significantly improves the commercial value and processing efficiency of pistachios.
With two available models and an adjustable opening angle of up to 200° or 330°, this automatic pistachio slitting machine is suitable for both medium-scale processors and industrial nut processing plants.
Applications of the Pistachio Slitting Machine
This pistachio opening machine is widely used in:
- Pistachio processing plants
- Nut snack production factories
- Export-oriented nut grading and packaging facilities
- Food factories handling closed-shell pistachios
It is designed specifically for unopened or partially opened pistachios, helping processors maximize yield and market acceptance.
Working Principle of the Pistachio Opening Machine
The pistachio slitting machine uses a mechanical cutting and positioning system:
- Pistachios are fed evenly into the slitting zone
- The machine automatically aligns each nut
- Precision cutters slit the shell along the natural seam
- Opening depth and angle are adjustable according to processing requirements
This process ensures:
- Controlled shell opening
- Minimal kernel damage
- Uniform and consistent opening results
Model 1: Standard Pneumatic Opening Machine (TZ-180)
The Cost-Effective Choice for Small to Medium Batches.
This model utilizes a pneumatic (air-operated) system combined with mechanical control to perform a straight slot cut on the nuts.
- Power Supply: Runs on standard 220V single-phase power, making it easy to use in smaller workshops.
- Mechanism: Uses a specific mold conveyor to hold nuts in place while a blade cuts a precise slot.
- Capacity: Processes up to 50kg (100 jin) per hour.
Model 2: Advanced Servo Ring-Cut Machine (TZ-320)
The Industrial Choice for Premium Presentation.
This fully automatic machine uses a hybrid electric-pneumatic system driven by a powerful servo motor. It is capable of “Ring Cutting” (Circular opening), which looks cleaner and is easier to open.
- Smart Control: Equipped with a Touch Screen PLC and automated processing programs.
- High Power: Features a 380V three-phase 3kW motor plus a 1.95kW dual servo system for high-speed precision.
- Adjustable Opening Angle: As confirmed by our engineering data, the cutting angle is highly customizable:
- Type 180 Setting: Maximum opening up to 200 degrees.
- Type 320 Setting: Maximum opening up to 330 degrees (almost a full circle cut).
- Capacity: Higher output of 90kg (180 jin) per hour.

How to Choose the Right Pistachio Slitting Machine?
TZ-180: Suitable for medium production volumes and standard pistachio opening needs
TZ-320: Recommended for higher output, wider opening angle, and more demanding export markets
Both models can be integrated into a complete pistachio processing line, including grading, roasting, cooling, and packaging equipment.
