Automatic Salad and Leafy Greens Processing Line

Greens Processing Line Product Overview

The Automatic Salad and Leafy Greens Processing Line provides an integrated solution for commercial and industrial fresh-cut vegetable production.The complete system combines vegetable sorting, trimming, cutting, lifting, vortex washing, clean-water rinsing, product collection, and centrifugal dewatering. Each processing stage can be configured according to the type of leafy vegetable, required cutting size, washing requirements, and target production capacity.

The reference line is designed for approximately 500 kg/h to more than 1500 kg/h, allowing the configuration to be adapted to different production scales.

A dual-stage vortex washing system provides gentle but intensive cleaning for delicate leafy products. After washing, excess surface water is removed by centrifugal dewatering, preparing the vegetables for inspection, weighing, packaging, or further processing.

Key Features

1. Complete Processing Solution
Integrates sorting, cutting, conveying, washing, rinsing, collecting, and dewatering into one coordinated production line.

2. Dual-Stage Vortex Washing
Primary and secondary vortex washers provide two-stage washing and rinsing for leafy vegetables.

3. Gentle Washing Process
Water circulation and bubbles move vegetables through the washing tank with limited mechanical impact, making the system suitable for delicate leafy products.

4. Adjustable Cutting Size
The reference vegetable cutter provides an adjustable cutting range of approximately 1–40 mm.

5. Adjustable Dewatering
Centrifugal speed and operating time can be adjusted according to different vegetable characteristics.

6. Flexible Production Capacity
The line can be configured for production capacities from approximately 500 kg/h to over 1500 kg/h according to the reference system.

7. Modular Configuration
Individual machines can be selected, removed, upgraded, or expanded according to the required production process.

8. Suitable for Delicate Leafy Vegetables
The line is designed for lettuce, spinach, parsley, celery, cabbage, chicory, leek, and similar fresh vegetables.

9. Easy Production Line Integration
Additional equipment for inspection, weighing, packaging, chilling, or conveying can be connected according to the final production process.

How to Choose the Right Salad Processing Line

Before selecting the equipment, it is recommended to confirm the following information:

1. What vegetables will you process?
   For example: lettuce, spinach, cabbage, celery, parsley, or mixed salad vegetables.
2. What is the required capacity?
   Please provide the target production rate in kg/h.
3. Will the vegetables be processed whole or cut?
   This determines whether a cutting machine is required.
4. What cutting size is required?
   Different salad products may require different cutting specifications.
5. How dirty are the incoming vegetables?
   Soil level and raw-material condition affect the washing configuration.
6. Is a sanitizing wash required?
   If yes, the sanitizer type, concentration, contact time, and rinse requirements should be confirmed according to the customer’s validated process.
7. Is chilled washing water required?
   A chiller can be incorporated where low-temperature washing is needed.
8. What final moisture level is required?
   This helps determine the centrifugal dewatering configuration.
9. What packaging system will be used?
   The line discharge can be coordinated with downstream weighing and packaging equipment.

FAQ

What is a salad processing line?
A salad processing line combines multiple machines for preparing fresh vegetables, typically including sorting, cutting, washing, rinsing, dewatering, and preparation for packaging.

What vegetables can this line process?
It is suitable for lettuce, iceberg lettuce, spinach, cabbage, parsley, celery, leek, chicory, and other suitable leafy vegetables.

What is the production capacity?
The reference line can be configured from approximately 500 kg/h to more than 1500 kg/h.

Why does the line use two vortex washers?
The first washer provides the main cleaning stage, while the second can provide additional washing and clean-water rinsing. This is particularly useful for leafy vegetables with folds and irregular surfaces.

Will vortex washing damage lettuce leaves?
The system is designed to use circulating water and bubbles for relatively gentle product movement rather than aggressive mechanical agitation. Actual settings should be adjusted according to the vegetable variety and condition.

Can the cutting size be adjusted?
Yes. The reference cutting machine provides an adjustable cutting range of approximately 1–40 mm.

How is water removed after washing?
A centrifugal dehydrator rotates the vegetables inside a perforated basket to remove excess surface moisture. Speed and cycle time can be adjusted according to the product.

Can cold water be used for washing?
Yes. A water chiller can be added when chilled-water washing is required.

Can the production line be customized?
Yes. Capacity, conveyor dimensions, cutting equipment, washing stages, dewatering equipment, line layout, and downstream connections can be configured according to the project.
