Peaches are among the most delicate fruits in the world. One wrong move during sorting and the fruit is bruised, unsellable, and worthless. Here's why electronic weight sorting is the only safe choice.
Why Peaches Are Different
Peaches are famous for their succulent flesh, rich flavor, and tender, smooth texture. But that same tenderness that makes them so appealing to eat also makes them extremely vulnerable during post-harvest handling.
Here's the problem: after picking, peaches come in all sizes. To maximize market value, they need to be sorted and graded. But traditional sorting methods — whether manual labor or mechanical graders — often do more harm than good.
Manual sorting is slow, labor-intensive, and inconsistent. Workers handling thousands of peaches a day inevitably bruise some of them.
Roller graders and cup sizers — which work well for firmer fruits like apples or citrus — can be disastrous for peaches. The rolling motion, the friction, and the drops between stations all take a toll on delicate peach skin and flesh.
The Hidden Cost of Bruising
A bruised peach doesn't just look bad. It loses shelf life, spoils faster, and gets rejected by buyers — especially in export markets where appearance standards are non-negotiable.
For growers and packers, this translates directly into:
· Lower grades — bruised fruit gets downgraded, reducing revenue
· More waste — spoiled fruit never makes it to market
· Rejected shipments — export buyers don't accept damaged fruit
· Damaged reputation — inconsistent quality means lost customers
The problem isn't that peaches are difficult to sort. The problem is that most sorting equipment wasn't designed for peaches.
A Better Way: Electronic Weight Sorting
This is where electronic weight sorting changes the game.
Instead of rolling peaches between rollers or dropping them into cups, an electronic weight sorter handles each peach individually and gently. Here's how it works:
· Each peach is carried in a soft-padded cradle
· It is weighed with ±2g accuracy by a precision electronic scale
· Based on the weight, it is directed to the appropriate packing lane
· Low drop heights and soft padding at every transition point minimize impact
The result? Peaches are sorted accurately without bruising — preserving the tender flesh and delicate skin that buyers expect.
The key difference: Roller graders and cup sizers rely on physical contact and mechanical movement — which bruises peaches. Electronic weight sorters use gentle, controlled handling from start to finish.
Two Configurations for Different Operations
Fstsort offers two electronic weight sorter configurations, each designed for a different scale of operation:
Rotary Electronic Sorter — Compact and space-saving, ideal for small to medium packing lines. It fits in tight spaces and delivers consistent ±2g accuracy with 6 weight grades at 16,000 pcs/h.
Linear Electronic Sorter — High-capacity solution for large-scale and export packing. Available in 1, 2, or 4 lanes, delivering up to 25,000 pcs/h per lane with 9–12 customizable weight grades.
What both share: soft padding everywhere — on the elevator, connecting plates, and packing tables. Low drop height — minimal falling distance at every point. And ±2g accuracy — meeting the tightest market specifications.
These systems aren't just for peaches. They're also widely used for apples, avocados, pears, citrus, tomatoes, plums, apricots, and passion fruit.

Ready to Sort Peaches Without the Bruises?
Every season, growers lose thousands of dollars to bruised fruit — fruit that could have been saved with the right equipment. The choice is simple: keep using methods that damage your peaches, or switch to a sorter that treats them with the care they deserve.
Your peaches have value. Don't let the wrong equipment take it away.
