Key Product Features

Anti-Bruise Cups: Food-grade, soft-edged ABS polymer cups cradle delicate citrus rinds to eliminate friction and rind oil release.

IP65-Rated Electronics: Dust and moisture-isolated enclosures allow for safe packhouse washdowns and long-term durability in humid environments.

Space-Efficient Circular Design: Utilizes a rotary layout that drastically minimizes factory floor footprint compared to long, linear lane-sorters, making it ideal for compact packhouses.

FAQ

Q: Can this circular sorter handle different types of citrus fruits on the same machine?

A: Yes. The weighing cups are universally designed to handle oranges, lemons, mandarins, and small grapefruits. You can easily adjust the weight parameters for different crops via the pre-set profiles in the PLC touch screen.

Q: How does the machine ensure the citrus fruit doesn't bruise during sorting?

A: We use food-grade ABS weighing cups lined with soft-touch rubber borders. The discharge chutes are set at a precise, gentle decline angle, ensuring fruits slide into collection bins via gravity rather than dropping hard.

Q: What is the maximum number of weight grades this machine can sort?

A: Our standard circular model sorts into 4 to 8 distinct weight classes. However, through our OEM services, we can extend the circular matrix to accommodate up to 10–12 custom weight grades based on your sorting requirements.

Q: How accurate is the weighing sensor at high speeds?

A: The machine is equipped with ultra-sensitive electronic load cells that maintain an accuracy tolerance of $\pm 1\text{g}$ to $\pm 2\text{g}$ even when running at maximum operational capacity.

Q: Is the electrical panel compliant with North American or European grid regulations?

A: Absolutely. We construct our electrical cabinets to order using either 220V/380V (Europe) or 460V 3-Phase (USA/Canada) electrical layouts, utilizing CE, UL, and Schneider/Siemens components.

Q: What is the estimated manufacturing lead time?

A: For standard configuration circular sorting units, our manufacturing cycle is 20–30 days. Fully customized lines featuring custom feeding integrations take roughly 40–50 days.

Q: How complex is the cleaning and maintenance routine for this machine?

A: The machine features an open-frame design, allowing for quick daily wipe-downs and debris removal. Because it utilizes a mechanical tipping layout rather than intricate pneumatic pistons for each cup, maintenance needs are minimal.

Q: What type of warranty do you provide to international buyers?

A: We offer a full 12-month comprehensive warranty covering all mechanical, structural, and electronic parts. Replacement components are shipped via priority air express at our expense during the warranty window.
