Citrus Orange Fruit Sorting Machine for Fruit Processing Plant

The orange sorting machine is an automated device specifically designed for sorting citrus fruits. It primarily utilizes electronic weighing sensor technology to detect the weight of each orange, automatically classifying them into different grades based on preset weight ranges. The orange sorting unit comprises components such as a feed conveyor, weighing and sorting unit, grading channel, and collection device. Oranges of different grades can be transported to corresponding exit areas for either automated packaging or manual selection.

Citrus Fruit Sorting Machine Principle:

Upon entering the grading channel, each orange passes through an independent weighing module. The system’s high-precision sensors automatically detect the weight of every orange and transmit the data in real time to the central control system. Based on pre-set weight grading standards (e.g., Grade I: 180g+, Grade II: 150–180g, Grade III: 120–150g), the control system automatically activates pneumatic pushers or diverting devices to direct oranges into their corresponding grading channels.

Key Features of the Orange Sorting Machine:

• High-precision weighing sorting: the citrus fruit sorting machine achieves accuracy within ±1g, ensuring consistent grading results.
• High automation: Fully automated process from feeding, weighing, grading to discharging, significantly reducing manual labor and boosting production efficiency.
• Gentle conveying design: Minimal contact between oranges and orange sorting machine during transport prevents abrasions or bruises, preserving smooth peel integrity.
• Multi-grade adjustability: Configurable with 2 to 12 grading levels to accommodate varying production demands, suitable for fruit processing facilities of all scales.

Other Pre-processing Steps for Orange:

Before entering the orange sorting unit, oranges typically undergo a series of pre-processing steps to ensure grading accuracy and product appearance quality. Key steps include:

1. Washing:

Post-harvest oranges often carry surface impurities. Washing machines effectively remove these contaminants.

2. Air Drying:

Air dryers remove surface moisture to prevent skin rot or uneven wax application caused by residual water droplets.

3. Waxing:

Applying a layer of food-grade wax solution enhances surface gloss, reduces moisture evaporation, and extends the oranges’ shelf life.

 

After these pre-processing steps, the oranges are evenly fed into the citrus fruit sorting machine for weight detection and sorting, ensuring a smooth and efficient workflow throughout the entire process.
