1.5 T/H Vegetable Washing Line in Vietnam

How Did Hadof Design The Vegetable Washing Process for Vietnamese Fresh-Cut Vegetable Processor?

During our initial discussions, Mr. An explained the customer's vegetable procurement and production targets. The factory purchased 3,000-4,000 tons of vegetables annually from surrounding agricultural cooperatives. Its main raw materials included carrots, potatoes, white radishes, beetroots, cabbage, spinach, lettuce, and celery. These root vegetables and leafy vegetables often carry mud and field residues. Демек, the customer needed a reliable vegetable washing procedure that removes soil, removes pesticide residues, and dewaters the produce. This client’s workshop reserves 330 m² for the vegetable processing project. Осы уақытта, he set a project budget between 50,000 және 55,000 US dollars. So our engineers designed a straight-line vegetable washing system with a capacity of 1.5 т/сағ. This line occupies about 120-160 м², with an overall length of about 19.7 meters. This arrangement left additional space for operators, routine cleaning, equipment maintenance, and future workflow adjustments. We recommended a three-stage bubble washing procedure, followed by vibrating dewatering and optional centrifugal dehydration. All food-contact parts use SUS304 stainless steel. Also, the automatic vegetable washing line reduces 8 to 3 workers. Содан кейін, this client will save about 1,300-1,700 USD every month. The equipment holds CE certificates and test reports. It aligns with Vietnam food safety regulations, HACCP standards, and ISO standards.

Which Machines Did Hadof Recommend for the 1,500 KG/H Vegetable Washing System?

• Three-Stage Bubble Washing Machines for Root and Leafy Vegetables

  Our proposal included three bubble washing machines in series to physically separate different washing tasks. The first vegetable washer removes dust, mud, and floating impurities. The second machine handles chemical washing and disinfection. Ақырында, the third machine uses clean water for the final vegetable rinse. Оның үстіне, we customized each bubble washer size to 4,815×1,714×1,538 mm with a 6.15 кВт қуат. According to Mr. An’s requirements, our team upgrade thickness of the cleaning tank bottom plate from 1.2 мм to 2 мм and frame specification to 50×50×2 mm. Alternating aeration outlets distributes bubbles across the tank bottom. The top spray assembly includes 24 nozzles operating at a specified pressure of 8 bar. Also, we added a gantry frame and a double-layer waterproof control cabinet to meet the customer’s requirements of increasing the equipment size and weight.

• Disinfection and Water Management Systems

  This part contains a chemical dosing system, a pH/ORP monitor, three ozone generation units, and a water recirculation system. А 300 L dosing tank works with a metering pump and connects to the washing section through pipes. Қосымша, the pH/ORP monitor improves the consistency of the chemical preparation. Three air cooling ozone units serve the three washing tanks. Each unit starts and stops automatically by a timer. A coarse filter works with this water treatment and recirculation unit. Сонымен қатар, a coarse filtration stage helped remove suspended solids before recirculation. Осылайша, this system saves about 30 to 35% of the water.

• Vibrating Dewatering & Centrifugal Vegetable Dehydration

  After washing, the vegetables entered a vibrating dewatering machine for continuous free-water removal. This process reduces water carryover and eases subsequent handling, storage, or packaging operations. Also, this dehydrator have 0.5 кВт қуат, 6 мм screen openings, 3 мм plate thickness and IP67 waterproof protection. Next, he could transfer washed vegetables using a turnover cart with three baskets. Alternatively, two centrifugal vegetable dehydrators could remove additional surface moisture from suitable products like salad or cutting vegetables. Each centrifugal dewatering machine have the capacity of 15 kg per batch және 1.1 кВт қуат. Сондықтан, the customer could select the appropriate dewatering procedure according to the characteristics of cabbage, spinach, lettuce, celery, and other vegetables.

How Did Hadof Arrange The Delivery, Shipping, And Installation of The 1,500 KG/H Vegetable Washing Line?

• Shipment Service

  For the delivery method, we packed every complete 1.5 t/h vegetable processing machine in a fumigation-free plywood crate. Оның үстіне, we treated the inner cavities against moisture and rust, fixed all moving parts and packed the wearing parts separately with clear labels. Сонымен қатар, we loaded the whole 1.5 t/h vegetable cleaning line into one 40HQ container. The container traveled from Hadof’s factory in Zhengzhou to Qingdao Port by truck. Содан кейін, the container shipped to Cat Lai Port in Ho Chi Minh City, Vietnam. The ocean freight for this 40HQ container costs about 1,800 USD. The inland trucking costs about 600 USD. So the total freight estimate reaches about 2,400 USD. The sea transit takes about 10–14 days. Hadof shipped the container on September 15, 2025. The container arrived at Cat Lai Port around September 29, 2025. Mr. An handled the import customs clearance at the destination port, and we provided all technical documents and shipping papers.

• Installation Service

  For the installation service, Hadof provided the general arrangement drawing after the contract signing. Одан әрі, our company delivered the three-dimensional drawing within 15 working days after the deposit payment. Also, we delivered the water, electricity, and foundation requirement list. Ақырында, we sent one technician to the Mr. An client’s factory in Đà Lạt, Lâm Đồng Province, Vietnam. This technician completed the on-site installation, the commissioning, and the initial operation guidance. What’s more, we provided five days of free installation service. The technician trained the operators in daily cleaning, maintenance, and ozone safety. The client’s production started in early October 2025.
