Product Overview

This fully automatic mixed vegetable weighing and packaging line is custom-developed for packaging mixed ingredients including mushrooms, kidney beans, and green beans. It specifically solves common industry pain points of irregular-shaped, fragile, and multi-ingredient mixed vegetables. The production line integrates automatic feeding, precision weighing, intelligent conveying, bag forming, filling and sealing functions, realizing full-process unmanned operation. It effectively eliminates manual weighing errors, low packaging efficiency, high material loss and high labor costs. Widely applicable to fresh mixed vegetables, frozen mixed vegetables and pre-made vegetable packaging scenarios, it serves as core intelligent processing equipment for standardized and large-scale production of vegetable food factories.

Industry Pain Points & Solutions

Mixed vegetable packaging faces prominent industrial difficulties due to huge differences in material shape, specific gravity and texture. Our production line adopts targeted optimized design to completely solve mainstream production bottlenecks and meet the requirements of modern vegetable deep processing:

• Pain Point 1: Unstable Proportion & Weighing Deviation:

  Mushrooms are fluffy, kidney beans are strip-shaped, and green beans are granular. Traditional single-weighing equipment cannot adapt to multi-form mixed materials, resulting in uneven ingredient proportion and inconsistent net weight.

  Solution: Adopt dual-weighing coordination system of 14-head combination weigher + 4-head linear weigher to classify and weigh different materials accurately, ensuring consistent mixing ratio and standardized product specifications.

• Pain Point 2: Fragile Materials & High Breakage Rate:

  Fresh vegetables are tender and easily squeezed, broken or spilled during conveying and feeding, leading to poor finished product appearance and high material waste.

  Solution: Equipped with decentralized vibration feeding, gentle climbing conveying and stable tray feeding structure, realizing low-loss and non-extrusion material transportation to maximize product integrity.

• Pain Point 3: Heavy Labor & Low Efficiency:

  Traditional mixed vegetable packaging relies on manual sorting, weighing, proportioning and bagging, featuring slow speed, large human errors and limited production capacity.

  Solution: Realize full automatic operation from feeding to finished product output, completely reduce manual intervention and significantly improve continuous production capacity.

• Pain Point 4: Disjointed Processes & Unstable Operation:

  Discrete traditional equipment causes frequent material stacking, jamming and material breakage, resulting in discontinuous production and low overall efficiency.

  Solution: Modular integrated design with highly coordinated each unit, ensuring smooth process connection, low failure rate and stable long-term operation.

Core Advantages

Precise Weighing with Stable Accuracy

Equipped with dual-weighing system of 14-head combination weigher and 4-head linear weigher, targeting the different specific gravity and shape characteristics of mixed vegetables. The ultra-high weighing accuracy reaches ±2g, effectively avoiding weight deviation and proportion imbalance, fully complying with international food inspection and supermarket supply standards.

High-Speed Continuous Production

The optimized mechanical structure and intelligent control system support a stable packaging speed of 45BPM (bags per minute). It runs continuously without jamming, greatly improving factory output and meeting the mass production demands of medium and large vegetable processing enterprises.

Specialized Material Protection Design

The entire conveying and weighing system is customized for mushrooms, kidney beans and green beans. Adopting flexible feeding and stable conveying technology, it avoids material extrusion, breakage and spilling, reduces production loss and improves finished product qualification rate.

Fully Automatic & Labor-Saving

Realize one-stop automatic operation including material conveying, quantitative weighing, proportional mixing, bag forming, filling and sealing. No manual intervention is required for core processes, reducing labor costs and human operation errors.

Integrated Structure & Easy Maintenance

Adopt compact modular layout with stable operation and low failure rate. The equipment is easy to clean, maintain and overhaul, fully meeting the hygienic production standards of food processing workshops.

Full Production Process Flow

The mixed vegetable weighing and packaging line features tightly connected processes and classified precise metering for different materials, realizing one-stop closed-loop production from raw materials to finished products. The standard operation flow is as follows:

Raw Material → Vibratory Feeding & Dispersion → Gentle Climbing Conveying → Precise Weighing (14-head Combination Weigher for Granular Main Materials + 4-head Linear Weigher for Fluffy/Strip Materials) → Accurate Material Mixing & Collection → Stable Tray Lifting Feeding → Vertical Packaging Machine (Automatic Bag Forming, Filling & Sealing) → Finished Product Output

Process Description: After raw materials are put into the production line, the vibratory feeder uniformly disperses materials to avoid accumulation and jamming. The climbing elevator gently transports vegetables to the weighing unit without damage. The dual-weighing system works independently and collaboratively: the 14-head combination weigher accurately measures granular green beans, while the 4-head linear weigher precisely weighs fluffy mushrooms and strip-shaped kidney beans. The accurately proportioned mixed materials are collected and conveyed stably to the packaging station via the tray elevator. Finally, the vertical packaging machine automatically completes bag making, filling and sealing, outputting neat and well-sealed finished products with high efficiency and stability throughout the whole process.

Applicable Materials

Specially designed for mixed packaging of mushrooms, kidney beans and green beans. Compatible with packaging of fresh and frozen mixed vegetables, supporting customized material proportion schemes to meet diverse packaging demands of pre-mixed vegetables and frozen vegetable bags.

Production Line Configuration

The whole production line adopts modular integrated design with highly coordinated supporting equipment to realize fully automatic closed-loop operation. The core configuration is as follows:

1. Vibratory Feeder: Realize uniform and controllable material dispersion, prevent material accumulation and blocking, and ensure stable and uniform feeding for subsequent precise weighing.

2. Climbing Elevator: Gently lift and transport vegetable materials, prevent material spilling and abrasion, and adapt to flexible conveying requirements of fragile vegetables.

3. 14-head Combination Weigher: Core high-speed weighing unit, suitable for precise metering of granular and regular vegetable materials with fast weighing speed and high stability.

4. 4-head Linear Weigher: Assist in accurate proportion calibration, adapt to fluffy and irregular materials, and make up for weighing errors caused by different material specific gravity to ensure uniform mixing ratio.

5. Tray Elevator: Stably receive mixed materials after weighing, accurately convey materials to the packaging station, and avoid material spilling and mixing disorder.

6. Vertical Packaging Machine: Complete automatic bag forming, quantitative filling, edge sealing and finished product output, with neat packaging appearance and tight sealing performance.
