Fresh-cut Mango Weighing & Box Packing Production Line

Automate fresh-cut mango packaging with an integrated weighing and box packing solution from LEESOLU. Designed for diced and cubed mangoes, this production line combines an inclined elevator, an 10-head three-layer combination weigher, a synchronized box conveyor, and an automatic box pressing machine to streamline the process from feeding to finished packs.

With a target weight of 500 g per box, a target weighing accuracy of ±5 g, and a rated output of up to 50 boxes per minute, the system helps fresh fruit processors improve portion consistency, reduce repetitive manual handling, and achieve more efficient box packing.

Key Specifications

• Target Pack Weight: 500 g per box

• Target Weighing Accuracy: ±5 g

• Rated Output: Up to 50 boxes/min

• Weighing System: 10-head, three-layer combination weigher

• Product Contact Material: Food-grade 304 stainless steel

• Control System: PLC with touchscreen interface

• Packaging Format: Fresh fruit boxes with customizable dimensions

Actual weighing accuracy and production output depend on fruit condition, cut size, moisture content, box dimensions, and the final line configuration. Performance should be verified through product testing.

1. Automatic Fresh Mango Weighing and Box Packing

Fresh-cut mangoes present specific challenges for automated packaging. The fruit pieces are soft, irregular in shape, and often retain surface moisture or natural juice. These characteristics can affect feeding consistency, weighing stability, and product presentation.

LEESOLU's fresh mango weighing and box packing production line integrates material feeding, combination weighing, box positioning, and box pressing into one coordinated system.

Instead of relying on operators to weigh every portion and fill each box manually, the line uses a multihead combination weigher to calculate suitable weight combinations and discharge the selected portion into a positioned container. The conveyor then transfers the filled box to the pressing station for closure.

This integrated approach is designed to help processors:

• Improve consistency in 500 g fruit portions.

• Reduce repetitive manual weighing and filling.

• Coordinate weighing and box transfer within one production line.

• Minimize unnecessary product handling.

• Support more consistent finished-pack presentation.

• Simplify production management through centralized controls.

The system can also be configured for other diced or cubed fruits following an evaluation of the product characteristics and packaging requirements.

2. Key Features of the Fresh Fruit Packaging Line

10-Head Three-Layer Combination Weigher for Accurate Portioning

The combination weigher is the core weighing unit of the fresh-cut mango packaging line. Eight weighing heads work together with a combination algorithm to identify a suitable combination of measured portions that meets the target weight.

Inclined Elevator for Controlled Material Feeding

Consistent feeding is essential for stable weighing performance. The inclined elevator transfers prepared mango pieces from the loading point to the combination weigher.

Synchronized Box Conveyor for Accurate Positioning

The box conveyor transports empty containers to the filling station and moves filled boxes toward the next operation.

With position detection and coordinated discharge signals, the system is designed to align each box beneath the weighing discharge point before releasing the fruit portion.

Automatic Box Pressing Machine

After filling, the containers move to the box pressing station, where the lids are pressed into position according to the selected box design.

The pressing unit helps reduce the need for repetitive manual lid closing and creates a more continuous packaging workflow.

PLC Control and Integrated Line Management

A PLC-based control system with a touchscreen interface coordinates the main production operations.

The modular layout also allows the main equipment units to be arranged according to available factory space and production requirements.

3. How the Fresh Mango Packaging Line Works

The complete process follows five main stages:

Product Preparation → Inclined Feeding → Combination Weighing → Box Filling → Box Pressing and Discharge

Step 1: Product Preparation and Feeding

Prepared mango cubes or diced mango pieces are loaded into the inclined elevator. The elevator transfers the fruit to the feeding section above the combination weigher.

For better handling, the fruit should be cut to a reasonably consistent size and drained to remove excessive free juice before entering the line.

Step 2: Combination Weighing

The feeding system distributes the mango pieces among the weighing heads. The control system evaluates the available weight combinations and selects a suitable combination for the programmed target weight.

For a standard application, the target is set to 500 g per box. Actual performance depends on the characteristics of the product and the validated operating settings.

Step 3: Automatic Box Filling

An empty box is positioned beneath the discharge point by the box conveyor. Once the box position and weighing cycle are synchronized, the selected mango portion is discharged into the container.

This process reduces the need for operators to manually portion and transfer every batch.

Step 4: Box Pressing

The filled box moves along the conveyor to the pressing machine. The machine presses the lid into place according to the compatible container design.

Step 5: Finished Product Discharge

Closed boxes are transferred to the line outlet for subsequent labeling, inspection, sorting, or manual collection.

Additional equipment can be considered when the application requires a more complete fresh produce packaging solution.

4. Applications and Compatible Products

This fruit weighing and packing machine is primarily designed for fresh-cut mangoes and may be adapted for other fruit products with similar physical characteristics.

Primary Application

Fresh-cut Mango Cubes and Diced Mango

Suitable for evaluating automated portion weighing and box filling for retail fruit packs, prepared fruit products, and fresh-cut fruit processing operations.

Other Potential Applications

• Pineapple cubes.

• Cantaloupe and melon pieces.

• Watermelon cubes.

• Dragon fruit pieces.

• Mixed fresh fruit assortments.

For mixed-fruit packs, a customized feeding and weighing arrangement may be required to control the proportions of different ingredients.

Recommended Product Preparation

For more consistent operation, we recommend:

• Keeping fruit pieces within a reasonably uniform size range.

• Draining excessive free juice before weighing.

• Evaluating the fruit's softness, stickiness, and tendency to cling to metal surfaces.

• Confirming the container dimensions and filling volume.

• Conducting product trials before finalizing the line configuration.

Fresh-cut fruit varies significantly in moisture, maturity, and texture. Compatibility and achievable performance should therefore be assessed using representative production samples.

5.Technical Specifications

The specifications above describe the intended application. Final performance, packaging compatibility, and line configuration are subject to confirmation after reviewing product samples and customer requirements.

6. Why Choose LEESOLU for Fresh Fruit Packaging?

Integrated Equipment Configuration

The inclined elevator, combination weigher, box conveyor, and pressing machine are designed to operate as a coordinated production line rather than as disconnected workstations.

Product-Specific Engineering

Fresh-cut mangoes require careful consideration of product softness, surface moisture, cut dimensions, and discharge behavior. These factors should be assessed when configuring the feeding and weighing system.

Hygienic Equipment Design

Product-contact components are specified in 304 stainless steel, with removable parts where applicable to support cleaning and maintenance. The cleaning method and water-resistance requirements should be confirmed for each machine assembly.

Flexible Packaging Configuration

The conveyor layout, feeding height, and compatible box dimensions can be evaluated against the customer's available factory space and packaging format.

Support for Line Integration

The line can be assessed for connection to downstream equipment such as labeling machines, inspection systems, and sorting stations, depending on the required process and available interfaces.
