Bubble Vegetable Washing Machine KN-305
The KN-305 Bubble Vegetable Washing Machine is a high-efficiency washing solution designed for cleaning leafy vegetables, root vegetables, herbs, and various agricultural products. Combining high-density air bubble agitation, water circulation, and high-pressure spray rinsing, the machine effectively removes dirt, sand, insects, and pesticide residues while preserving the freshness and integrity of delicate produce. Manufactured from food-grade SUS304 stainless steel, the KN-305 is an ideal choice for central kitchens, fresh-cut vegetable processing plants, catering companies, and food processing factories. Bubble washing technology is widely used in commercial vegetable processing because it provides gentle yet highly effective cleaning for delicate produce.

The KN-305 Bubble Vegetable Washing Machine is engineered to provide continuous, gentle, and efficient cleaning of vegetables and fruits. A high-pressure air bubble generator creates dense bubbles inside the washing tank, allowing products to tumble naturally in circulating water, loosening soil, dust, insects, and surface contaminants without damaging delicate leaves or soft produce.
A built-in circulating water pump continuously recycles filtered water to improve washing efficiency while reducing water consumption. After the bubble cleaning stage, the integrated top spray system performs a secondary rinse with clean water, ensuring higher product cleanliness before discharge.
With its longer washing tank compared to the KN-304, the KN-305 provides an extended washing path, making it suitable for higher cleaning efficiency and continuous production. Constructed entirely from food-grade SUS304 stainless steel, it offers excellent hygiene, corrosion resistance, and reliable long-term performance. It can operate independently or as part of a complete vegetable processing line.
