An orange citrus sorting machine is an optical inspection and grading system. It automatically grades oranges based on their quality characteristics. A NIR citrus sorting machine combines a high-speed camera, optical sensors, and optional near-infrared (NIR) detection. An orange color sorter machine can assess the fruit's color, ripeness, surface appearance, and selected internal quality indicators.
The equipment can be configured as an orange color sorter machine, an NIR citrus sorting machine, an orange weight grading machine, or a multi-parameter citrus grading system according to the customer's fruit characteristics and quality requirements. It can also be used in combination with orange cleaning machines and waxing machines.
Orange Brix Sorting Machine Features
The sorting criteria can be configured according to the required application.
- Fruit color：Separates green, yellow, orange and unevenly colored fruit.
- Maturity: The NIR citrus sorting machine can determine the ripeness of the inside of an orange.
- Surface defects: Detects visible scars, spots, bruises and discoloration.
- Shape: Identifies irregular or deformed fruit.
- Sweetness and tartness: The Orange Brix sorting machine can determine the sweetness and tartness of oranges based on infrared reflection.
- Weight: The oranges are weighed in real time and can be graded according to their weight.
The exact detection capability depends on the selected camera, NIR sensor configuration and sorting software.
How Does Nir Citrus Sorting Machine Work?
- Feeding: Oranges enter the NIR citrus sorting machine via a conveyor. The conveyor system evenly distributes the oranges. Each orange enters the inspection area individually, ensuring one orange per tray.
- Dynamic Monitoring: Oranges continuously roll within the tray, ensuring 360-degree detection.
- Optical and Camera Inspection: The orange color sorter captures images as oranges pass through the inspection area. The orange AI sorting machine uses these images to determine the orange's peel color, surface blemishes, shape, and more.
- Internal Quality Inspection: The NIR citrus sorting machine emits infrared light and collects the light reflected from the oranges. The orange brix sorting machine analyzes the spectrum to determine the brix value of the oranges. This is an intelligent grading device that can distinguish the sweetness and tartness of oranges without cutting them.
- Grading: The NIR citrus sorting machine compares detected characteristics with predefined grading criteria. Each orange is assigned to a predefined quality category.
- Discharge: Based on the grading results, the sorting mechanism sends each orange to the corresponding discharge port.
Key Advantages of Orange Color Sorting Machine
- Non-destructive grading: The Gelgoog orange brix sorting machine completes internal quality inspection without cutting the fruit. This is especially important for situations where oranges need to be kept intact for fresh fruit market sales. Parts in contact with the fruit can be made of flexible materials to prevent damage from bumps and knocks.
- Customizable design: Customers can adjust grading parameters to their specific needs and set different quality grades.
- High quality: The NIR citrus sorting machine grades oranges based on appearance, weight, and internal quality. This meets the demands of the high-end market. Quality far surpasses manual or weight-based grading.
- High output: The orange color sorter machine can process 3-12 tons of oranges per hour. Meets the production needs of large-scale fruit and vegetable processing plants.
- Multi-purpose: The orange brix sorting machine can also be used to grade apples, lemons, pomegranates, etc. Customers can process different fruits in different seasons, improving equipment utilization.
Applications of Orange Color Sorter Machine
Orange brix sorting machine is suitable for:
- Orange packing houses
- Citrus exporters
- Fruit distribution centers
- Commercial orchards
- Fresh fruit processors
- Citrus cooperatives
- Premium supermarket suppliers
It can also be configured for other citrus fruits such as mandarins, tangerines, lemons and grapefruits, subject to sensor and software calibration.
