500kg/h Lavatrice a bolle di bietole per la pulizia delicata delle verdure

Inside the equipment, a high-pressure blower injects a large volume of micro-bubbles into the washing tank, creating a continuously churning "air-water mixture." Under the intense impact of the bubbles and the surging water flow, dirt and debris—lodged between the leaves or at the junctions of the stalks and roots—are rapidly dislodged from the Swiss chard and settle at the bottom of the tank. Nel frattempo, a circulating pump and filtration system at the top of the unit filter and recycle the water, maintaining its cleanliness. An elevating mesh conveyor at the discharge end automatically transports the washed Swiss chard to the next processing stage; the entire operation is continuous and automated, requiring no manual agitation.

1. High-Density Bubble Generation System
A built-in high-power blower works with specialized microporous aeration pipes to generate fine bubbles (approximately 0.5–2 mm in diameter). These are evenly distributed throughout the washing tank, ensuring full coverage of the Swiss chard from the feeding stage to discharge.

2. Food-Grade All-Stainless Steel Construction
The entire unit—including the washing tank, nastro trasportatore, tubazioni, and housing—is constructed from 304 acciaio inossidabile. It is corrosion-resistant, facile da pulire, and complies with sanitary standards for export-grade food processing.

3. Variable-Frequency Conveyor Belt
The discharge lifting section features a variable-frequency motor, allowing for stepless speed adjustment. This accommodates Swiss chard leaves of varying varieties and thicknesses, enabling precise control over washing duration and discharge flow.

4. Two-Stage Circulating Water Filtration System
A drainage outlet is located at the bottom of the washing tank. Circulating water is reused after undergoing dual filtration—passing through a stainless steel mesh screen and a sedimentation zone—thereby reducing the frequency of water changes and overall water consumption.

1. Zero damage to leafy greens; ideal for the crisp, delicate nature of Swiss chard
Swiss chard features broad, thin, tender leaves and crisp, brittle stalks; traditional high-pressure spraying or mechanical brushing methods easily cause damage, curling, or even breakage. This equipment utilizes a gentle air-bubble detachment principle, ensuring no hard objects come into contact with the leaf surface, resulting in an intactness rate of over 98% after washing.

2. Efficient removal of stubborn dirt and grit from stalk crevices
Swiss chard stalks are broad, flat, and curved with longitudinal grooves, making the base prone to trapping soil. Micro-bubbles penetrate deep into the stalk folds and crevices at the base, using continuous micro-vibrations to "dislodge" hidden dirt—delivering cleaning results far superior to manual soaking or simple spraying.

3. Continuous automated operation for significant labor savings
With a processing capacity of 500 kg all'ora, the system replaces 8–12 manual washing stations. Only one operator is required for loading, while washing and conveying are handled automatically, significantly reducing labor costs and management complexity.

4. Acqua- and energy-saving design lowers operating costs
A circulating water filtration system limits water consumption to just 30%–40% of that used in traditional washing methods. Inoltre, the blowers and pumps utilize high-efficiency, energy-saving motors, offering distinct energy-efficiency advantages during full-load operation.

For fresh-cut vegetable processing plants
The equipment integrates directly into existing production lines, connecting seamlessly with cutting, dewatering, and packaging machinery. With a processing capacity of 500 kg/h—enabling the handling of 4 tons of Swiss chard during an 8-hour shift—it allows plants to rapidly fulfill large orders and enhance delivery capabilities.

For export-oriented vegetable enterprises
Gentile, damage-free washing preserves the integrity, crispness, and vibrant color of the leaves. The resulting high-quality Swiss chard more easily meets the produce inspection standards of destination countries, thereby increasing the product's premium value.

For central kitchens and ready-to-cook/eat meal facilities
The system effectively removes pesticide residues and soil, ensuring hygiene compliance during the washing stage and mitigating food safety risks. It also minimizes manual handling, aligning with HACCP food safety management system requirements.

For farms and cooperatives
The equipment is easy to operate and maintain, with a single worker capable of managing the entire washing line. This enables rapid processing of large volumes of raw produce during peak harvest seasons, preventing losses due to backlog and enhancing on-site primary processing capabilities.

Designed with the structural characteristics of Swiss chard and common washing challenges in mind, this 500kg/h bubble washing machine utilizes gentle air-bubble technology to deliver high efficiency and minimal product damage while saving both water and labor. Whether for fresh-cut produce distribution, export processing, or central kitchen pre-processing, this equipment ensures a stable and reliable washing solution for your production line.
