Air Bubble Vegetable Washing Machine

• Leafy Greens: Lettuce, Spinach, Cabbage, Kale, Parsley, Cilantro.
• Soft Fruits: Strawberries, Blueberries, Grapes, Tomatoes, Cherries.
• Cut Vegetables: Sliced peppers, onion rings, diced carrots.
• Mushrooms: Delicate fungi that bruise easily.
• Salt Removal: Desalting pickled vegetables (the bubbles help dissolve salt quickly).

• Vegetable & fruit processing factories
• Central kitchens/catering companies/Agricultural product packing plants
• Supermarkets and fresh food distribution centers
• Frozen or ready-to-eat vegetable production lines
• Seafood & aquatic product washing (multi-purpose models)

1. Air Bubble Agitation. A bubble generator or aerator at the bottom of the wash tank pumps pressurized air into the water. This creates millions of tiny rising bubbles, which agitate the water and produce circulating currents. Vegetables in the tank turn, tumble, and rub gently against the water flow, dislodging dirt, sand, and debris from all surfaces.
2. Bubble Impact & Burst. When bubbles burst on contact with produce surfaces, they generate local micro-impacts that dislodge dirt and residues without damaging delicate skins.
3. High-Pressure Spray Rinse. The vegetable washing machine has spray nozzles above the tank that provide a secondary rinse, washing off loosened soil and foam.
4. Continuous Conveyance. Vegetables are moved through the washer on a stainless steel conveyor belt. This allows continuous high-throughput cleaning, and the speed can be adjusted to match different produce types.
   Water Filtration & Recycling. Bottom filters trap heavy dirt, while clean water can be recycled in a closed loop to save water and reduce waste.

• Washing Tank: Made of food-grade SUS304 Stainless Steel to resist rust and corrosion from water and acidic fruit juices.
• Air Bubble Generator System: High-efficiency air pumps create uniform bubble distribution.
• Mesh Conveyor Belt: A stainless steel mesh belt that lifts the washed vegetables out of the water and moves them to the next stage (usually drying, cutting, or packing). Adjustable speed to suit different vegetable types.
• High-Pressure Spray Nozzles: Located above the conveyor belt. Provide secondary rinsing for enhanced cleanliness. As the vegetables are lifted out of the dirty tank water, these nozzles blast them with clean, fresh water to remove any remaining dirty water or foam.
• Circulating Water Pump: Filters and recycles the tank water to reduce consumption. Ensures constant water flow and cleaning stability.
• Ozone Generator: Injects Ozone (O₃) gas into the air bubbles to sterilize the produce while it washes.
• Control Panel: Allows speed & operation adjustment. Easy operation with adjustable washing intensity and conveyor speed.

1. Feeding: Vegetables are dumped into the inlet end of the tank.
2. Bubble Washing: The product enters the bubbling zone. The turbulence loosens soil, dust, and bugs.
3. Sedimentation: Heavy dirt (sand/stones) falls through a mesh grid to the bottom of the tank (sediment area) so it doesn’t mix back with the vegetables.
4. Floating Debris Removal: Light debris (bugs, hair, plastic bits) floats to the top and is often skimmed off by a specialized overflow filter.
5. Forward Movement: The flow of water pushes the vegetables toward the conveyor belt.
6. Secondary Rinse: As the vegetables climb the conveyor belt, they pass under the high-pressure spray headers for a final rinse with clean water.

✔ Gentle Washing. Best for cleaning leafy greens, root vegetables, and soft fruits.
✔ High Efficiency & Throughput. The vegetable washing machines can handle 500–5000 kg/hour or more.
✔ Water-Saving & Eco-Friendly. Recirculation and filtration systems can save a lot.
✔ Improved Food Safety. These washing machines enhance hygiene and help reduce pesticide residues.
✔ Adjustable & Flexible. Adjustable conveyor speed and wash intensity. Slower for delicate leaves, faster for firm vegetables.
✔ Durability & Hygiene. Made mainly from food-grade stainless steel (e.g., SUS304), resist corrosion and are easy to clean — ideal for HACCP, ISO, and other food safety requirements.

Integrating an Air Bubble Vegetable Washing Machine into a complete vegetable processing line converts a standalone cleaning task into a high-efficiency, automated production system. In a commercial setting, the vegetable washing machine is rarely used alone; it is the “heart” of a sequence that takes raw harvest to shelf-ready packaging. In the vegetable processing lines, the air bubble washer is installed after pre-treatment and before dewatering or cutting. It is designed to work seamlessly with upstream and downstream equipment to create a continuous, automated, hygienic workflow from raw vegetables to finished products.

Standard Vegetable Processing Line Workflow: Vegetable Preparation – Washing – Dewatering – Packaging.

Before the vegetables reach the air bubble washer, they must be prepped.

•  Vegetable Hoisting/Elevating: A Conveyor Elevator lifts raw produce from floor-level crates and drops them into the vegetable washer. This replaces manual lifting.
• Sorting/Inspection Table: A conveyor belt where workers manually remove rotten items, stones, or weeds before washing.
• Vegetable Cutting/Slicing (For Fresh-Cut Salads): If you are producing bagged salads or potato chips, a Vegetable Cutting machine is placed before the washer. The chopped leaves and chips fall directly into the air bubble washer to remove the sap released during cutting.

• Single Stage: One air bubble washer for general cleaning.
• Double Stage (Sequential Washing): High-standard lines often use two air bubble washers in a row.

Once the vegetables leave the washer, they are soaking wet. Excess moisture causes rot, so this stage is critical.

The vegetable washer’s conveyor drops produce onto a vibrating perforated deck. It shakes off heavy water droplets and spreads the pile evenly.

A conveyor belt with powerful fans mounted above. It blows air to dry the surface of hard vegetables (tomatoes, peppers, bags).

For salads, the vibrating machine feeds into a “Spin Dryer.” This spins the leaves at high speed to remove moisture without heating them.

• Elevator: Moves dried produce up to the weighing scale.
• Multi-head Weigher: Automatically portions the vegetables (e.g., exactly 200g per bag).
• Packaging Machine: Seals the produce in plastic bags (often Nitrogen-flushed to prevent oxidation).
