Eggplants come in all shapes. Round, long, oval—each variety has its own characteristics. Can one grading machine handle them all? Fstsort's work with customers in Australia and Vietnam provides the answer.
Three Shapes, One Challenge
Eggplants are not all the same. Botanically, they fall into three main shape categories:
· Round eggplants — Spherical, large, weighing 300–1000g. Firmer flesh, tighter texture, fewer fruits per plant. Good quality and highly marketable.
· Long eggplants — Slender or long rod-shaped, some with pointed tips. Thin skin, loose flesh, soft texture, few seeds. The most common variety in many Asian markets.
· Egg (dwarf) eggplants — Oval or oblate, bulb-shaped. Some are softer, some denser. Good quality with unique culinary uses.
Each shape presents a different grading challenge. Round eggplants roll smoothly and predictably. Long eggplants don't roll the same way—they can shift, tilt, or wedge into gaps that don't represent their true size. Dwarf eggplants fall somewhere in between.
For packers handling multiple eggplant varieties, the question is: can one machine sort them all?
What Fstsort Learned from Real Customers
Last year, Fstsort sold an eggplant washing, drying, and grading machine to a customer in Australia. The machine was used to process round eggplants—and the sorting effect was very good.
More recently, Fstsort customized an eggplant grading machine for a customer in Vietnam. After repeated tests, the results were clear: except for very slender long eggplants that proved difficult to grade by diameter, all other eggplant varieties sorted very well.
The key takeaway: for packers who primarily process round, oval, or standard long eggplants, the Fstsort grader delivers accurate, consistent results—and it's continuously being refined to handle even more varieties.
How the Grader Works
The Fstsort eggplant grader is designed for commercial packing lines. It uses a roller grading system that sorts eggplants by diameter with precision and gentle handling.
