It is widely suitable for large-scale packaging scenarios such as fresh fruit processing factories, fresh food supply chain workshops, e-commerce fruit warehouses and supermarket supporting packaging workshops, enabling standardized, large-scale and refined fruit packaging production.

Product Highlights & Core Advantages

Specially developed for high-volume box packaging of cherry tomatoes and small tomatoes, this fully automatic packaging line is equipped with a high-performance 24-head dual AB combination weigher (12×2 configuration). It realizes integrated automatic operations including feeding, lifting, precision weighing, and box filling. Featuring unmanned operation, minimal weighing error, ultra-low fruit damage rate, adjustable packaging specifications and multi-product compatibility, it serves as an essential automated equipment for fruit processing enterprises to achieve cost reduction, efficiency improvement and standardized mass production.

• Dual-Weighing High-Speed Mass Production:

  The 12×2 AB dual weigher works alternately to avoid jamming and low-capacity issues of single-weighing equipment. It ensures non-stop high-speed weighing and fully meets large-scale continuous production demands.

• Precision Weighing & Loss Control:

  Intelligent quantitative matching technology delivers high weighing accuracy with uniform net weight for each box. It effectively eliminates weight deviation and greatly improves finished product qualification rate.

• Gentle Fruit Protection Design:

  Adopting fully smooth and flexible conveying structure without extrusion or collision, the equipment perfectly protects the appearance integrity of delicate fresh fruits and minimizes material loss.

• Multi-Fruit Compatibility:

  Not limited to cherry tomatoes, it is widely applicable for box packaging of various small round and oval fruits, including kumquats, winter jujubes, plums and small citrus fruits.

• Flexible & Adjustable Specifications:

  Equipment parameters can be freely adjusted according to customer’s box size and weight standards, supporting diversified packaging specifications to fit diverse market orders.

• Intelligent Monitoring & Stable Operation:

  Built-in intelligent monitoring system real-timely tracks feeding, conveying and weighing status. It ensures controllable operation, low failure rate and long-term stable running

Production Line Configuration & System Composition

Featuring scientific layout and modular assembly design, the production line covers a small area with convenient installation and simple daily maintenance. The standard full set of configurations are as follows:

• Horizontal Feeding Conveyor: Delivers stable and uniform automatic feeding with constant speed, effectively preventing material accumulation and blocking to ensure continuous and stable feeding.

• Inclined Lifting Conveyor: Perfectly connects the front feeding system and rear weighing unit, stably lifting materials for continuous and seamless procedure connection.

• 24-Head Combination Weigher (12×2 AB Dual Weigher): The core weighing unit with dual 12-head weighing systems working alternately. It significantly improves weighing speed and accuracy, fully adapting to high-volume mass production.

• Automatic Box Filling Machine: Achieves precise positioning and quantitative filling, ensuring neat box loading without material spilling or leakage.

• Intelligent Monitoring System: Real-timely monitors material blanking and equipment operating status to guarantee uniform feeding, coherent procedures and stable overall operation.

Working Principle & Production Process

Adopting a closed-loop automatic production mode, all modular units operate in precise linkage with smooth and standardized production procedures:

Step 1: Automatic Horizontal Feeding 

Fresh fruits are placed on the horizontal feeding conveyor and delivered at a constant flexible speed. The stable and bump-free conveying effectively avoids skin damage to cherry tomatoes and realizes continuous and uniform material supply.

Step 2: Inclined Lifting & Material Docking:

The conveyed materials are stably lifted by the inclined conveyor and accurately delivered to the feeding end of the weighing machine, solving material disconnection, accumulation and breakage problems to ensure production continuity.

Step 3: Intelligent Quantitative Weighing by AB Dual Weigher:

Materials enter the 24-head combination weigher. The dual 12-head units work independently and alternately. Intelligent algorithm rapid combination matching realizes high-precision quantitative weighing while ensuring high production speed.

Step 4: Precise Automatic Box Filling:

Once the weighing standard is met, the equipment automatically triggers blanking. Materials fall evenly into the packaging boxes with precise positioning calibration, ensuring uniform filling and consistent product appearance of each box.

Step 5: Continuous Closed-Loop Mass Production:

The whole line operates in closed-loop cycle without manual duty. It supports long-term continuous operation, greatly improving fruit box packaging capacity and meeting large-scale production requirements.

Application Scope & Suitable Industries

Applicable Products

Mainly applicable for cherry tomatoes and small tomatoes. It also supports packaging of various small hard round or oval fresh fruits, including kumquats, winter jujubes, green jujubes, plums, small oranges and sugar oranges.

Detailed Technical Advantages

Dual-Weighing Structure for Higher Production Capacity

Different from ordinary single combination weighers, the 12×2 AB dual-weighing structure supports dual-station synchronous and alternate discharging, avoiding equipment idling and jamming. It greatly boosts production efficiency and easily handles high-volume order production.

Flexible Conveying for Ultra-Low Fruit Loss

All conveying, lifting and blanking links adopt flexible protection design without hard collision or extrusion. The original fruit appearance is well preserved with an extremely low damage rate, maximizing the commercial value of fresh fruits.

Adjustable Parameters for Diversified Packaging

It supports free adjustment of filling weight, feeding speed and conveying frequency. Compatible with various box types and weight specifications, it flexibly adapts to diversified customized packaging demands in the market.

Intelligent Operation & Low Maintenance Cost

Equipped with an intelligent visual monitoring system with fault early warning function. The intuitive operation interface allows easy operation after simple training. Daily cleaning, disassembly and maintenance are convenient, effectively reducing later operation costs.

Integrated Structure for Stable & Durable Use

The modular integrated layout features low operation noise and low failure rate. The corrosion-resistant and easy-to-clean body material adapts to humid and dusty fresh food workshop environments, extending the equipment service life.

Product Value & Industrial Benefits

• Cost Reduction & Efficiency Improvement: Full automatic unmanned operation replaces multiple manual packaging positions, greatly cutting labor salary and management costs. The significantly improved production capacity enables fast capital return for enterprises.

• Standardized Quality Upgrade: Machine unified quantitative packaging completely solves the problems of unstable manual weighing and uneven box filling. Uniform packaging specifications and exquisite product appearance effectively enhance market competitiveness.

• High Cost-Performance with Multi-Function: One machine covers multiple types of small fruit packaging production, eliminating repeated equipment procurement and saving enterprise equipment investment and site occupation costs.
