From shell integrity to kernel spotting, from insect damage to foreign material, the margin between premium quality and rejected shipment can be narrow. For years, processors relied on operators, manual sorting, and standalone optical sorters to maintain standards. It worked — but it had limits.
How It was (and mostly still is).
Even nowadays, most pistachio facilities operated with fixed machine thresholds. A sorter is set up at the beginning of a shift and fine-tuned based on visual checks and lab samples. If incoming product changes — moisture (leading to mold), staining, defect profile — adjustments are reactive.At the same time, labor is becoming more difficult to secure. for Brad Grubb, our Qcify representant in Australia, it's important to secure facilities in case of labor shortage too:
“Shortage of labor… automation and innovation is driven by that, being able to reduce labor cost while producing more product.”
For pistachio processors, especially those exporting internationally, the pressure was even higher. Quality was not just about appearance, it is contractual.
“Driven by customers, they want to know exactly what they get. High specs, and they want them to be adhered to. Slipping means whole containers will be shipped back.” Said Andrés Aspillaga, commercial partner for Chile and South America.
A rejected container is not just a quality issue, it is a financial problem.
So processors improved sorting equipment. They added more advanced optical systems. They refined defect classification. But fundamentally, the line still operated in segments: one machine at a time.
The future of Pistachio (and food sorting) is all connected.
The next evolution was not just better cameras — it was a shift in philosophy."The food production needs to be done by machine, with ‘repeatability’, without human error." Mentioned Andrés Aspillaga.
Repeatability became central. Not just removing obvious defects, but ensuring consistent performance shift after shift, lot after lot.
Pistachios are particularly complex in this respect. External shell defects — non-splits, staining, adhering hull — are only part of the challenge. Internal kernel issues such as spotting, immaturity, insect damage, or mold require deeper inspection logic. Add to that foreign materials like sticks, stones, leaf fragments, shell pieces,... and the inspection burden increases further, making it impossible to ensure desired specs without technology.
The installed base has matured. Systems are faster, more accurate, more stable.
But even now, most sorting lines still operate with static decision thresholds. Each machine optimizes within its own boundary, without fully understanding what is happening upstream or downstream. That is where the next leap begins. The future is now: Pack2Spec™ is interconnecting sorting.
According to Pieter Ieven, Qcify's CEO, with a strong focus on centralized data and system architecture, the future lies in connectivity:
“For me, it’s about building a fully connected system — one that can be deployed across multiple facilities, reduce operational footprint, and allow plants to run with fewer people while maintaining control.”
Pack2Spec™ introduces a patented real-time interconnected control architecture. Instead of isolated machines acting independently, sensors and sorters communicate continuously across the line. Decisions are not frozen at the start of the shift. They adapt to the product flowing through the system, ensuring specifications are met.
This matters in pistachios, where incoming quality fluctuates significantly.
Without coordination, processors face two familiar risks: over-sorting: rejecting good product and losing yield, or under-sorting: allowing defective product to pass and risking customer rejection. With interconnected feedback, defect removal rates can be maintained while minimizing unnecessary waste.
As Bert Switten emphasized when describing Qcify’s philosophy:
“We didn’t just sell machines — we designed them based on feedback… We wanted to build machines that people can actually use.”
Bert Switten, Director of Customer Service at Qcify, Inc.
For pistachio processors, this means moving from reaction to control. Instead of adjusting one machine at a time, the entire line behaves as a coordinated system.
What began years ago as a question about manual quality checks — raised by Raf Peelaers at the founding of Qcify — has evolved into something broader: not just inspecting nuts or almonds or pistachios, but managing their quality dynamically across the entire processing line.
The future of pistachio sorting is not another incremental machine upgrade.
It is interconnected intelligence — and with Pack2Spec™, that future is already here.
