In modern fruit and vegetable processing, automatic fruit and vegetable washing machines have become essential equipment for improving production efficiency and ensuring food hygiene and safety. Based on their cleaning principles and structural forms, common fruit and vegetable washing machines primarily include roller-type and bubble-type washing machines. The roller-type washing machine is further subdivided into three types: horizontal, vertical, and parallel.
The roller vegetable and fruit washer is an automated cleaning device that utilizes multiple food-grade brushes to rub, stir, and rinse fruits and vegetables as they rotate. These brushes effectively remove surface sediment, impurities, and even provide a light peeling effect. Depending on their structure and purpose, roller vegetable and fruit washers are primarily categorized into three types: horizontal, vertical, and parallel.
Working Principle: Uses rotating brushes and water spray to clean surface dirt. Best for: Root vegetables like carrots, potatoes, beets.
Horizontal roller vegetable and fruit cleaning machine
Applicable to: Root vegetables such as potatoes, carrots, ginger, yams, lotus roots, and sweet potatoes, as well as hard-skinned melons like winter melon and pumpkin.
The bubble-type fruit and vegetable washer utilizes a bubbling device at the bottom of a sink to generate a large number of bubbles. Through the tumbling, collision, and friction of the water, it gently and thoroughly cleans the surfaces of fruits and vegetables. It is widely used in the cleaning and processing of vegetables, fruits, seafood, and traditional Chinese medicines, and is particularly suitable for cleaning leafy vegetables and delicate fruits.
Working Principle: Uses high-pressure air to create bubbles that agitate and clean vegetables gently.
Difference Between Bubble Washer and Brush Roller Washer
Vegetable washing machines come in different designs, but two of the most common are the bubble washer and the brush roller washer. Each works differently and is better suited for specific types of produce.
1. Bubble Washer
How It Works:
Uses high-pressure air pumps to create water bubbles.
The bubbling action gently agitates the vegetables, loosening dirt, mud, and pesticide residues.
Often equipped with ozone sterilization or circulating water filtration for cleaner results.
Best For:
Leafy greens (spinach, lettuce, cabbage)
Soft fruits (tomatoes, strawberries, cherries)
Produce that requires gentle handling to prevent damage
Advantages:
Very gentle, reduces product bruising
Effective for washing delicate and irregularly shaped produce
Can handle large quantities with consistent cleaning
2. Brush Roller Washer
How It Works:
Equipped with multiple rotating brushes (nylon or soft hair) and spray nozzles.
The friction between brushes and produce removes soil, dust, and stubborn surface residues.
Best For:
Root vegetables (carrots, potatoes, ginger, taro)
Fruits with thicker skins (apples, pears)
Produce that needs surface scrubbing
Advantages:
Strong cleaning power for dirt-covered produce
Can also perform peeling if equipped with abrasive brushes
