In the clean vegetable processing production line, the eddy current cleaning machine is the core equipment in the raw material pretreatment stage, especially suitable for cleaning leafy vegetables (such as spinach and lettuce), root and stem vegetables (such as potatoes and radishes), fruits and vegetables (such as tomatoes and cucumbers), and other vegetables. It achieves efficient removal of sediment, impurities, insect eggs, and some pesticide residues on the surface of vegetables through a unique vortex generation principle, while also providing flexible protection for vegetables.
1、 Core working principle
The core of the vortex cleaning machine's work is the dual effect of "water flow swirling+bubble impact":
Multiple sets of high-pressure water pumps are installed at the bottom of the equipment, and the water flows through specially designed guide plates to form spiral vortices (with a flow rate of up to 1.5-2m/s), causing vegetables to roll irregularly in the water with the vortices and rub against each other to remove surface impurities;
At the same time, a large number of microbubbles (bubble diameter ≤ 0.5mm) are injected into the water through an air pump. The impact force generated when the bubbles rise and burst in the water can penetrate deep into the gaps of vegetables (such as the flower balls of broccoli and the folds of beans), removing hidden dirt.
This combination method can ensure the cleaning effect while reducing damage to vegetable tissues, solving the problems of low efficiency and incomplete cleaning in traditional manual cleaning.
2、 Key performance parameters and advantages
（1） Efficient cleaning capability
High cleanliness: Through the synergistic effect of vortex friction and bubble impact, the removal rate of sediment is ≥ 98%, and the removal rate of impurities such as insect eggs and hair is ≥ 95%. It can also reduce surface pesticide residues (degradation rate can reach 30% -50%, and can be increased to over 60% when combined with ozone generation devices). For example, when cleaning carrots with mud, it only takes 30-60 seconds to remove more than 90% of the surface soil, and the cleaning effect is much better than traditional spray cleaning.
Large processing capacity: Depending on the equipment model, it can process 500kg-5 tons of vegetables per hour (such as small equipment suitable for family farms, and large equipment meeting the production needs of central kitchens). Taking the common 2-ton/hour machine as an example, it can continuously process leafy vegetables such as spinach and lettuce, or root vegetables such as potatoes and carrots, without frequent downtime for feeding.
（2） Flexible protection design
Low damage rate: In response to the characteristics of leafy vegetables being easily damaged and fruit vegetables being easily bumped, the equipment adopts a food grade PP material cleaning tank and flexible guide plate to avoid scratches caused by metal contact. The intensity of eddy current can be adjusted by the power of the water pump (5.5-15kW). Leafy vegetables use low-intensity eddy current (damage rate ≤ 3%), while root and stem vegetables use high-intensity eddy current (damage rate ≤ 5%) to ensure the integrity of vegetable appearance.
Graded cleaning adaptation: For vegetables of different sizes (such as cherry tomatoes and tomatoes), the cleaning time can be controlled by adjusting the conveyor speed of the mesh belt (0.5-2mm/min). For small grain vegetables, the cleaning time can be extended (60-90 seconds), while for large volume vegetables, the cleaning time can be shortened (30-45 seconds) to avoid excessive cleaning and softening.
（3） Water saving and environmental performance
Water recycling: Equipped with a three-stage filtration system (filter screen+sedimentation tank+activated carbon), the cleaning wastewater can be recycled after filtration, with a water saving rate of over 60% (traditional flowing water cleaning consumes 5-8 tons of water per ton of vegetables, while vortex cleaning machines only require 2-3 tons).
Energy consumption optimization: Using variable frequency water and air pumps, the power can be automatically adjusted according to the type of vegetables, reducing no-load energy consumption by 30%; The overall operating noise of the equipment is ≤ 75dB, which meets the environmental protection standards for food processing workshops.
（4） Automation and ease of maintenance
Intelligent control: Set cleaning time (10-120 seconds), eddy current intensity, water temperature (room temperature -40 ℃, hot water cleaning can enhance oil removal effect) and other parameters through PLC touch screen, support storage of cleaning formulas for 10+vegetables, one click switching without the need for re debugging.
Convenient cleaning: The bottom of the cleaning tank is equipped with a tilted sewage outlet, which can quickly discharge sediment and sand; The filter and guide plate adopt a snap on design, which can be disassembled and cleaned within 30 minutes to avoid the growth of bacteria due to residual impurities.
3、 Applicable scenarios and supporting connections
Applicable vegetable types:
Leafy vegetables: spinach, lettuce, lettuce, etc., can remove rotten leaves, sediment, and aphids;
Rhizomes: potatoes, radishes, carrots, etc., with the assistance of a brush roller, can remove fine sand from the skin;
Fruits and vegetables: tomatoes, cucumbers, eggplants, etc., remove surface pesticide residues and fuzz;
Cauliflower: Broccoli, cauliflower, etc., deep into the crevices to remove hidden impurities.
Production line connection: It can seamlessly connect with the front-end sorting machine and the back-end draining/peeling machine, forming a continuous process of "sorting cleaning draining processing". For example, cleaned potatoes can be directly fed into the peeling machine, reducing manual transportation and improving the efficiency of the entire vegetable production line.
Toxic function: Some high-end models are integrated with ozone generators (ozone concentration 0.5-1mg/L), which synchronously sterilize during the cleaning process, reducing the total number of bacteria on the surface of vegetables by more than 90% and extending the shelf life of clean vegetables (1-2 days longer than unsterilized products).
The clean vegetable processing vortex cleaning machine has become an indispensable equipment in the industrial production of clean vegetables due to its high efficiency, low damage, water conservation and environmental protection. Through intelligent control and flexible design, it can not only meet the efficiency requirements of large-scale production, but also ensure the freshness and appearance of vegetables, providing key guarantees for the safety and quality of clean vegetable products.
