Bell pepper sorting is a key step in ensuring uniform product specifications and enhancing market value. Different sorting methods are suitable for different production scenarios. The following is an introduction to the core sorting methods and their advantages:

1, Bell pepper manual sorting

Relying on human vision and touch, bell peppers are screened one by one on a fruit sorting table (such as the 4-meter fruit sorting table mentioned above). By observing the color and shape of the skin and touching the hardness, defective products with deformities, rot, damaged skin, and uneven colors are removed. At the same time, they can be preliminarily classified by size.

Core Advantages

High Screening Accuracy: This system can identify subtle defects (such as tiny spots and slight rot) that are difficult for machines to detect, making it particularly suitable for high-end markets with extremely high quality requirments (such as boutique supermarkets).

Flexibility: Screening criteria can be adjusted based on real-time needs (such as adding requirements such as "no insect eyes" or "intact fruit stems") without the need for complex parameter settings.

Low Cost and Low Entry Point: No specialized equipment investment is required; only simple training is required for implementation, making it suitable for small processing plants or small-batch production scenarios.

2, Bell pepper weight grading and sorting

Using weighing sensors, bell peppers are quickly weighed during transportation. Combined with preset weight ranges (such as 80-120g for small fruits, 120-180g for medium fruits, and 180-250g for large fruits), the mechanical structure allocates the bell peppers to corresponding channels, achieving automatic sorting by weight.

Core Advantages

High Sorting Efficiency: A single-channel sorting speed can reach over 60 pieces/minute (multiple channels can be stacked), far exceeding manual sorting speed and suitable for large-scale production.

Stable Accuracy: Weighing error can be controlled within ±2g, eliminating standard fluctuations caused by manual sorting fatigue and ensuring consistent weight for peppers of the same specification.

Easy Automation Integration: Seamlessly integrates into washing, drying, and packaging production lines (such as the packaging line mentioned above), reducing manual handling and reducing waste.

3, Bell pepper optical sorting

The system uses high-definition cameras to capture images of bell peppers and, combined with AI image recognition technology, analyzes the peppers' color (e.g., dark green/light green for green bell peppers, red/yellow/orange for colored bell peppers), skin defects (e.g., scratches, spots, rot), and maturity. It can also assist in identifying deformed fruit. After software sets standards, peppers that don't meet the requirements are removed by air jet valves or robotic arms, or sorted by category.

Core Advantages

Multi-dimensional Sorting: It can simultaneously sort by color, defects, and maturity, for example, classifying green bell peppers by "dark green (ripe)" or "light green (not fully ripe)" or removing defective ones with black spots, far exceeding single weight sorting.

Non-contact and Minimal Damage: Sorting with air jets avoids mechanical pinching and damage to the bell pepper skin, making it particularly suitable for colorful bell peppers with delicate skin.

Data Traceability: It records sorting data for each batch (such as defective rate and percentage of each color), facilitating production quality control and traceability.

4, Bell pepper size sorting

Peppers are sorted based on their diameter, height, and other dimensional parameters through mechanical baffles, roller spacing adjustment, or optical size measurement (such as laser ranging). For example, by setting rollers at different spacings, small peppers fall from the gaps to the corresponding channels, while large peppers are transported to subsequent channels along with the rollers. Alternatively, the volume of peppers can be precisely calculated through optical measurement and sorted according to preset size ranges.

Core Advantages

Strong Standardization: Bell peppers are sorted based on their apparent size (e.g., diameters 6-8cm, 8-10cm), meeting the needs of catering businesses for uniform size and ease of cutting, and the packaging industry for adaptability to fixed packaging boxes.

Simple Structure and Easy Maintenance: Mechanical size sorting equipment (e.g., drum-type) lacks complex electronic components, resulting in a low failure rate and significantly lower maintenance costs than optical sorting equipment.

Suitable for a Variety of Pepper Varieties: No parameters need to be adjusted for color or weight; simply replace the baffle or adjust the spacing to accommodate the size of different bell pepper varieties (e.g., sweet peppers and horn peppers).
