1,500 KG/H Leafy Green Cleaning System

How to Design a 1.5 T/H Leafy Vegetable Washing And Dewatering Plan?

Our engineers will analyze raw materials, daily output, workshop conditions, and downstream equipment before selecting washing stages, equipment length, and dehydration process. Actually, leafy green like lettuce, спанак, Chinese cabbage, and mustard greens carries soil, dust, and field impurities on the surface. Most vegetable processing plants prefer to send the clean vegetables directly to the sorting, рязане, or packaging areas, while also avoiding excessive mechanical compression of the leaves during the washing process.

For 1.5 t/h clean leafy vegetable production needs, our team recommends the following washing procedure:

Material Sorting → Primary Bubble Washing → Chemical Dosing and Washing → Final Clean Water Rinsing → Vibrating Dewatering → Optional Centrifugal Dewatering → Sorting or Packaging.

Междувременно, your existing equipment and investment budget determine whether the leafy vegetable cleaning line requires feeding, сортиране, рязане, or packaging machines.

Three-Stage Washing Technology

A 1.5 t/h three-stage washing system allows for the separation of distinct leafy vegetable processing tasks.
First, the primary vegetable washing machine removes soil, dust, and floating impurities through bubble agitation and water circulation.
Next, the second washing stage involves washing through a chemical dosing system.
Finally, it uses clean water to remove remaining impurities and reduce treatment-liquid carryover.
This arrangement separates washing tasks and helps operators manage water quality across different processing stages.

Three-Stage Bubble Vegetable Washing System

The three-stage bubble washing system forms the core of our 1.5 T/H vegetable processing solution. First, we recommend 3 bubble washers connected in series, each with the capacity of 2,000 кг/ч, power of 6.15 kW and length of 4.8-5.0 meters. The machines combine bubble agitation with continuous conveying to handle different leafy vegetables. The first washer removes soil, sand, and floating impurities. Next, the second washer works with the chemical dosing system for disinfection and cleaning. Finally, the third washer uses clean water to rinse away residues from previous washing stages. Освен това, the machines use SUS304 structures, bubble agitation, overhead spraying, and variable-frequency conveying. We design the lifting structure allowing operators to clean and maintain inside the washing tank. Освен това, we can customize the frames, plate thickness, feeding and discharge heights, equipment connections, and waterproof control cabinets. For example, in our customized 1.5 T/H vegetable washing project in Vietnam, we added gantry frames, 2 mm thick stainless steel plates, double-layer waterproof control cabinets to meet the customer’s factory requirements.
Chemical Dosing & Water Management System

To support three-stage washing, we recommend one chemical dosing system, three ozone generators, and a water recirculation unit. The dosing system includes a 300 L mixing tank, metering pump, pH/ORP monitor, and connecting pipelines. Its pump delivers treatment solution to designated washers at adjustable rates of 0–150 L/h. Междувременно, pH/ORP monitoring helps operators assess solution conditions and manage sanitation. The three ozone generators support independent, timed operation in their respective washing stages. Въпреки това, operators must control ozone concentration, application methods, and operating conditions according to safety requirements. Освен това, the recirculation system transfers suitable reusable water to earlier washing stages. Proper replenishment, filtration, overflow control, and wastewater discharge help reduce unnecessary water consumption. Nevertheless, the final rinsing stage requires appropriate water quality. Следователно, the system must prevent untreated wastewater from entering the final clean-water rinsing tank.
Vegetable Dewatering & Transfer System

At the end of the washing line, we recommend a vibrating dewatering machine, a turnover cart, и 2 centrifugal vegetable dehydrators. Следователно, to reduce moisture after three-stage washing, we recommend adding a vibrating drainer to connect the future sorting and packaging operations. Also, it features a SUS304 structure, dimensions of 3,200×1,170×965 mm, и 0.5 kW power. Its vibration mechanism removes part of the free surface water while conveying vegetables toward the discharge outlet. Next, the turnover cart uses three baskets for vegetable collection and transfer. For vegetable products requiring further moisture removal, we recommend adding one or two basket-type centrifugal dehydrators for 15 kg per batch processing operation. Consequently, customers can use these machines for selected vegetables requiring more intensive dewatering. If customers require continuous, higher-intensity dewatering for their entire production output, our engineers will reassess downstream equipment quantities and processing capacities. Accordingly, we will adjust the equipment configuration and overall project budget.

How Much Plant Area and Installed Power Does a 1,500 kg/h Leafy Vegetable Washing Line Need?

For a medium-scale industrial leafy green project, the total equipment length, the operating aisles, the water recycling position, and the rear processing area also affect the real plant space. Accordingly, our engineers suggest a one-way material flow from the raw-material inlet to the clean-product outlet. In this way, the line reduces the cross movement of washed and unwashed vegetables in the operating area.

Leafy Green Cleaning Workshop Layout

☘The main equipment and maintenance area takes about 120–160 m². If you also need raw-material storage, basket cleaning, manual sorting, and packaging, we suggest a total area of about 250–300 m².

☘Освен това, we suggest that the client reserve enough cleaning and maintenance aisles on both sides of the leafy green washing line. The client should also place the dosing, water recycling, and auxiliary equipment in easy-to-service positions. If the client’s plant space is limited, we can also adjust the auxiliary device positions according to the production flow.

☘For an existing food processing workshop, we can adjust the equipment positions according to the client’s CAD floor plan. Междувременно, we can check the vegetable processing plant’s existing water supply, drainage, electrical, and ventilation conditions.

☘Notably, this 1.5 t/h leafy green washing plan uses a 380 V, 50 Hz, three-phase power source for the power supply. We can use about 25 kW as the initial power capacity reference. Въпреки това, the final power distribution design must follow the nameplate parameters of all motors, water pumps, and control devices.

How Does A 1,500KG/H Industrial Leafy Green Washing System Work?

For leafy vegetable processing projects with a capacity of 1,500 кг/ч, we recommend adopting a combination of three-stage bubble cleaning and dehydration, rather than relying on a single large-scale vegetable cleaning machine. This configuration separates preliminary impurity removal, chemical cleaning, and final rinsing, enabling operators to control the water quality, cleaning duration, and material conveying rate. Допълнително, the clean vegetables enter directly into a vibrating drainage unit, with the option of further centrifugal dehydration according to the requirements of the final product.

Primary Bubble Washing: The bubble washing machine agitates water to loosen soil, dust, and field debris from vegetable leaves. Междувременно, the conveyor transfers the vegetables toward the next cleaning stage.
Chemical Dosing: A chemical dosing unit introduces the prepared treatment solution into the second washing section; together with air bubbles and water flow, it ensures that the vegetables come into contact with the cleaning solution. This system requires operators to adjust the dosage and monitor the treatment status via pH/ORP monitoring equipment.
Final Clean Water Rinsing: Then, the final bubble washing machine rinses vegetables with clean water, helping to reduce impurities from earlier processes. We can design the direction of the water circulation based on the customer’s process requirements, thereby preventing wastewater from earlier stages from directly compromising the effectiveness of the final rinsing.
Обезводняване: After washing, the vegetables enter a vibrating drainer. It uses vibration conveying to remove the surface free water. Освен това, operators can use a centrifugal dehydrator for batch processing. Consequently, customers can select an appropriate level of dewatering based on the packaging requirements of different products.

FAQ of the 1,500 kg/h Leafy Vegetable Washing Line

Can This Plan Continuously Process 1,500 kg/h of Leafy Vegetables?

A client cannot judge the final output of a vegetable washing line only by one bubble washing machine’s rated capacity. Следователно, we define 1,500 kg/h as the design level of this washing line. Then, our team confirms the continuous capacity according to the actual process configuration. For different vegetables, the real output also depends on the leaf size, soil content, washing time, and rear dewatering method. To help clients evaluate the capacity, we usually consider the four factors below.

☑Raw material condition: Spinach, lettuce, зеле, and water spinach have different bulk densities and mechanical strengths. Consequently, their real output at the same conveying speed may differ.

☑Washing time: Soil-covered raw material may need a longer washing time. The client cannot raise output only by increasing the conveying speed.

☑Material connection: The feed and discharge heights, the conveying speed, and the buffering method must match. In this way, the line avoids vegetable accumulation.

☑Dewatering requirement: If every product needs centrifugal dehydration, the rear equipment capacity affects the continuous line output.

We suggest that the client define the rated feeding capacity and the real output after all required steps. The client should also test the equipment with real raw material during the acceptance.
Can One Washing Line Process Different Types of Leafy Vegetables?

This set of equipment suits lettuce, спанак, зеле, mustard greens, water spinach, and some leafy herbs. Въпреки това, different vegetables need suitable bubble strength, conveying speed, and dewatering method. Our team can help clients set the operating parameters for different products. Освен това, we can arrange reasonable batch changeovers and cleaning procedures. For soil-covered root vegetables, we usually recommend a dedicated brush washing machine or a peeling machine.
Can This Vegetable Cleaning Line Connect to Vegetable Cutting Machines and Packaging Machines?

Yes. The client can add vegetable cutting, сортиране, weighing, and packaging equipment according to the final product requirements. The client can place these machines at the front or rear of the washing line. For example, a client who produces fresh-cut lettuce can cut the leaves at a suitable position. Then, this client can arrange the fine washing and dehydration. Междувременно, a client who mainly sells whole washed leafy vegetables can finish washing and draining first. Then, the produce moves to sorting and packaging. The specific equipment order depends on the raw material condition, the cutting size, and the hygiene requirements.
