• Receiving
Receiving Stage:Efficient Onion Handling:
The first critical step in our fresh onion processing line is the receiving stage. This is where incoming onions are efficiently transferred and prepared for further processing.

Key components of the receiving stage include:
• Electric Bin Tipper: A smart and efficient tipper designed to gently empty bins or boxes containing onions. This ensures minimal damage to the product and prevents bruising.
• Product Accumulation & Even Flow Hopper: Even flow Hopper is a combination conveyor and hopper. This conveyor system plays a crucial role in controlling the flow of onions, ensuring a steady and even supply for subsequent processes. The Even flow Hopper converts irregular infeed flows into a constant outfeed.

By utilizing these advanced technologies, we guarantee a smooth and efficient transition of onions from the receiving area to the next stage of processing.

• Debris Removal
Debris Removal Stage: Ensuring Product Purity:
The second crucial stage in our fresh onion processing line is debris removal. This step is essential to eliminate any unwanted materials, such as broken pieces, small stones, or other debris, from the onion flow.

Our debris removal system incorporates:
• Debris Remover: This specialized equipment features a rotating screen with precisely sized holes. As onions and debris are fed onto the screen, the debris falls through the holes while the clean onions are carried forward to the outfeed. Mechanical shakers gently vibrate the screen to enhance the separation process.

By effectively removing debris at this stage, we ensure that only high-quality onions proceed to the subsequent processing steps, maintaining product integrity and meeting stringent export standards.

• Topping
Topping Stage: Precise and Efficient Onion Preparation:
The third essential stage in our fresh onion processing line is topping. This involves removing the foliage and roots from the onions, ensuring a clean and presentable product.

Our topping machine features:
• Rotating Blades: The onions are passed through rotating blades that accurately cut away the unwanted foliage and roots.
• Vibrating Screens: The produce is transported using vibrating screens, which help to remove any loose skins or dirt.
• Enclosed Housing: The enclosed design of the topping machine provides a safe working environment and reduces noise and dust levels.

By effectively topping the onions, we prepare them for further processing and packaging, ensuring a high-quality and visually appealing final product.

• Manual Sorting
Manual Sorting Stage: Ensuring Quality Control:
The fourth crucial stage in our fresh onion processing line is manual sorting. This step involves a thorough visual inspection of the onions by trained personnel to identify and remove any defects or substandard produce.

Our manual sorting system features:
• Belt Inspection Conveyor: A conveyor with a blue PVC belt provides a clear contrast against the onions, facilitating easy inspection. For exceptionally dirty onions, a web belt can be used to allow dirt, debris, and water to fall through, preventing their further contamination of the product.

By carefully inspecting each onion, we can ensure that only the highest quality produce proceeds to the subsequent stages of processing and packaging, maintaining a consistent level of excellence.

• Dry Brushing:
Dry Brushing Stage: Removing Residual Dirt and Skins:
The fifth essential stage in our fresh onion processing line is dry brushing. This step is crucial for removing any remaining dirt or loose skins that may have persisted after previous stages.

Our dry brushing system features:
• Adjustable Brushing Intensity: The brushing intensity can be adjusted to suit the specific needs of the onions, ensuring effective cleaning without damaging the product.
• Rotating Brush Shafts: A series of heavy-duty brush shafts rotate to gently remove excess skin and husk while simultaneously moving the onions forward along the brusher's bed.

By incorporating dry brushing into our process, we can deliver onions that are clean, free from impurities, and ready for packaging.

• Sizing
Sizing Stage: Precisely Sorting Onions by Size:
The sixth crucial stage in our fresh onion processing line is sizing. This step accurately separates onions into different size categories based on their intended market or customer preferences.

Our sizing system features:
• Roller Sizer: This versatile machine offers multiple size outputs in a single unit, handling a wide range of product sizes and shapes. By adjusting the spacing between the rollers, you can create specific size bands to meet your exact requirements.
• Lift Roller Design: The roller sizer is constructed from stainless steel and food-grade plastic materials, ensuring durability and safety. The bottom rollers are fixed, while the top rollers lift as they move forward, creating openings for onions to fall through based on their size.
• Individual Cross Conveyors: Each size category has its own dedicated cross conveyor, efficiently delivering onions of the same size to the next station in the processing line.

By precisely sizing the onions, we can optimize their value and ensure that they meet the specific demands of different markets or customer segments.

• Optical sorting and grading (optional)
Optical Sorting and Grading Stage: Precision Quality Control:
The seventh crucial stage in our fresh onion processing line is optical sorting and grading. This advanced technology utilizes cameras and sensors to accurately assess onions based on various quality criteria, including internal and external characteristics.

Key features of our optical sorting and grading system include:
• High-Speed Sorting: Onions are inspected at high speeds, ensuring efficient and effective quality control.
• Comprehensive Quality Checks: The system evaluates onions based on factors such as size, weight, shape, color, and internal quality.
• Advanced Cleaning: Extraction units keep the machine clean, preventing excessive dust and skins from interfering with the sorting process.
• Internal Inspection: Near-infrared technology provides reliable information about the internal quality of the onions.
• External Inspection: Cameras inspect the onions from multiple angles to assess color, skin condition, and size.
• Precise Grading: Onions are accurately weighed and deposited into the assigned exit bins based on their quality and sorting criteria.

By incorporating optical sorting and grading into our process, we can deliver onions of the highest quality, ensuring customer satisfaction and meeting stringent market standards.

• Packing
Packing Stage: Efficient and Gentle Onion Packaging:
The final stage in our fresh onion processing line is packing. This involves carefully transferring the onions into bins or bags for storage, transportation, and distribution.

Our packing system features:
• Vertical Bin & Bag Filler: This specialized equipment ensures gentle handling of the onions during the packing process.
• De-Elevator Mechanism: The de-elevator lowers and stops just before reaching the bottom of the bin or bag, allowing for controlled product flow.
• Soft Finger Conveyors: Gentle fingers on the de-elevator convey the onions into the bin or bag, slowly adjusting upwards to maintain a minimal distance between the conveyor and the onion level.
• Automatic Detection: The packing process stops automatically when the bin or bag is full, and resumes when a new empty container is detected.

By utilizing our efficient packing system, we can ensure that the onions are packaged with care, preserving their quality and minimizing damage during transportation.
