1. The “Triple-Action” Physics (It’s Not Just Bubbles)

Bubble Agitation + Rotary Brushing + High-Pressure Spray

Most cheap machines are just a jacuzzi for vegetables. They float the dirt, but they don’t remove it.

This system uses a 3-Stage Attack:

1. The Cavitation (Bubbles):An air pump forces air into the water tank. When these bubbles collapse against the surface of a Dragon Fruit or Tomato, they create a micro-shockwave. This dislodges dust and pesticide residue from the skin without bruising the flesh.
2. The “Tumbling” Brush:As the product moves up the incline conveyor, it hits the Rotary Brushes.

1. The Engineering Detail:These aren’t stiff floor brushes. They are soft food-grade Nylon. They gently roll the product. If you are washing Ginger or Turmeric, this step is non-negotiable to remove the clay soil.
   3. The Final Rinse:Fresh water (or ozonated water) is sprayed at 3-5 bar pressure at the very end. This ensures that no dirty tank water remains on the product.

 The “Water Bill” Trap (Read This Carefully)

Dual-Stage Filtration | Real-Time TDS Monitoring

In Vietnam and Thailand, industrial water costs are climbing.

A standard “flow-through” washer wastes 5 tons of water per hour. It’s financial suicide.

The Recycling Logic:This machine recirculates the water, but it doesn’t just pump dirty water back in.

• The Trap:Competitors claim “Water Recycling.” But if you look at their tank, it’s just a pump. After 20 minutes, you are washing chilies in mud soup.
• Our Solution:We use a Dual-Stage Filtration System (50-100 micron).

• Step 1:A coarse screen catches leaves and stems.
• Step 2:A sediment trap settles the sand.
• Step 3:TDS Monitoring. The machine measures the Total Dissolved Solids. If the water gets too dirty, it automatically bleeds a small amount and refills with fresh water. You save 80% of your water bill while maintaining hygiene.

Hygiene: The “Tropical” Rust Proofing

Full SUS304 | IP65 Electronics

In a humid factory in Penang, “Stainless Steel” is a loose term. Many workshops use 201 Steel. It looks shiny in the showroom. Six months later, it rusts.

• The Material:We use SUS304 with a thickness of 2.0mm.
• The Design:Look at the corners of the tank. They are Radius Corners (curved).

• Why?Sharp corners trap bacteria and algae. Curved corners allow your CIP (Clean-in-Place) system to actually work.
  • The Electronics:The control cabinet is IP65 Rated. You can spray the outside of the cabinet. The humidity won’t fry the VFD (Variable Frequency Drive).

 Technical Specs: The Real Numbers

Feature	Specification	Engineer’s Note
Capacity	500 – 2000 kg/h	This depends on density. 2000kg for Potatoes; maybe 800kg for Leafy Greens.
Power	7.5 – 15 kW	Requires 380V / 3-Phase. Do not try to run this on single phase.
Conveyor Speed	0.1 – 5 m/min	Adjustable via VFD. Slow it down for dirty Root Veg; speed it up for Apples.
Filtration	100 Micron	Self-cleaning filter option available.
Bubble Density	80 – 120 m³/h	Adjustable. Turn it down for delicate Strawberries.
Dimensions	3000×800×1200 mm	Modular. We can extend it to 10 meters if you need a longer soak time.

⚠️ Maintenance: The “Dirty Truth”

I will tell you what breaks so you can prevent it.

1. The Spray Nozzles:If you use hard water (borehole water), calcium will clog the spray nozzles within 3 months.

• The Fix:Soak the nozzle tips in vinegar or a descaling solution once a month. Don’t wait until the spray pattern looks weird.
  2. The Pump Intake:Operators get lazy. They don’t clean the primary filter screen. Leaves block the pump intake. The pump runs dry and burns out.
• The Rule:Clean the filter screen every 2 hours. It takes 30 seconds.
  3. The Chain Grease:The conveyor chain is underwater half the time. Standard grease washes off. You must use Water-Resistant Food Grade Grease. If you hear squeaking, you are already damaging the shaft.

❓ FAQ: Questions Factory Owners Ask Me

Q: Can I wash cut vegetables (like shredded cabbage) in this?A: Yes, but you need the “Floating Debris Remover” add-on. Cut vegetables release small bits that float. We add a rotating drum skimmer to catch these so they don’t clog the pump.

Q: Will it bruise my ripe Mangoes?A: No, if you adjust the settings. The VFD (Variable Frequency Drive) allows you to lower the bubble intensity and slow down the conveyor. For ripe fruit, we treat it like a spa, not a car wash.

Q: Can I add Chlorine or Ozone?A: Yes. The SUS304 tank is resistant to standard Chlorine concentrations (100-200ppm). However, Ozone is better for export because it leaves no chemical residue. We can integrate an Ozone Generator directly into the air pump line.

Q: How do I drain the mud?A: The tank bottom is sloped (V-shape). There is a large 2-inch ball valve at the bottom. Open it at the end of the shift, and the mud slides out. Don’t let mud sit overnight; it turns into concrete.——This is the sanitation standard required for 2026.
