1. Bubble Aeration Cleaning (Core Washing Process)
An air blower continuously feeds compressed air into perforated aeration pipes installed at the tank bottom. Masses of dense fine bubbles rise upward and burst when reaching the water surface. The instant bursting generates micro-impact force to rub crop surfaces, stripping dirt, insect eggs, residual pesticides and embedded grime without scratching tender fruit and chili peels. Circulating running water carries floating impurities toward the overflow drain for continuous sewage discharge.
2. Top High-Pressure Spray Rinsing
High-pressure spray pipes are mounted above the washing tank. Pressurized clean water sprays vertically down to flush off residual sundries, broken leaves and loose contaminants left after bubble cleaning, finishing secondary precision rinsing. The overflow water design separates dirty wastewater automatically while fresh water supplements the tank steadily.
3. Hydraulic Tilting Discharging (Unique Feature of Tilting Model)
Once washing finishes, hydraulic cylinders lift one end of the whole stainless steel washing tank. Supported by fixed rotating shafts, the tank tilts gradually. All cleaned materials slide down by gravity into receiving containers or follow-up processing equipment like air drying machines, eliminating manual fishing and greatly saving labor cost.
4. Optional Auxiliary Functions Principle
- Ozone sterilization system: Dissolves ozone into cleaning water to degrade pesticide residue and inhibit surface bacteria for fresh-keeping.
- Surge flow device: Side impellers create directional water flow to drive materials moving evenly inside the tank for consistent washing effect.
