Product Overview

The Multi-Nut Weighing, Packaging and Conveyor Production Line is a fully automated, integrated industrial packaging solution specially designed for mixed nuts, single-variety nuts and various granular snack foods. Engineered to solve the pain points of inaccurate manual weighing, low packaging efficiency and unstable product quality in the nut food processing industry, this production line realizes full-process automatic operation from material feeding, precise weighing, quantitative packaging to finished product conveying.

Adopting industry-leading 14-head combination weighing technology and matched with stable vertical packaging equipment and intelligent conveying systems, the entire line features high weighing accuracy, fast running speed, stable operation and wide applicability. It is widely suitable for packaging almonds, cashews, walnuts, pistachios, mixed nuts and other nut products, meeting the large-scale, standardized and high-quality production needs of food processing enterprises.

Complete System Composition

This automatic nut packaging production line adopts a modular integrated design, with each equipment unit perfectly matched and synchronously operated to ensure the continuity and stability of the entire production process. The complete system configuration is as follows:

• Independent Vibrating Feeding Plate: Adopts high-frequency vibration feeding technology, which can evenly and quantitatively transport bulk nut materials, effectively avoid material accumulation and blockage, and ensure uniform material supply for subsequent weighing procedures. It is suitable for irregular granular nut materials with different particle sizes.

• Bucket Elevator: Realizes vertical automatic lifting and conveying of materials, saves factory floor space, features stable lifting, low material damage rate and large conveying capacity, and efficiently transports materials from the feeding link to the weighing system.

• 14-Head Combination Weigher: The core precision weighing component of the production line. It uses intelligent algorithm combination weighing technology to complete rapid sampling and calculation of materials in multiple groups, realizing ultra-precise quantitative weighing and greatly reducing material waste caused by weighing errors.

• Vertical Packaging Machine: Completes automatic bag forming, filling, sealing, cutting and counting of nut products. It supports multiple packaging bag types, with tight sealing and beautiful packaging appearance, meeting the packaging standards of food-grade products.

• Finished Product Conveyor: Automatically transports the packaged finished nut products to the next process (such as sorting, boxing and warehousing), realizing uninterrupted assembly line operation and improving overall production efficiency.

• Supporting Conveyor Line: Connects all equipment modules in the whole line to form a closed-loop automatic production system, ensuring smooth material transmission and synchronous operation of each equipment.

Core Technical Parameters

This nut packaging production line achieves a perfect balance between high precision and high efficiency, with stable and reliable core performance indicators, which can effectively improve enterprise production capacity and product qualification rate:

• Weighing Accuracy: ±0.3g to ±1g

• Maximum Packaging Speed: 90 Bags Per Minute (90 BPM)

Benefiting from the 14-head multi-channel combined weighing technology, the equipment can maintain high-precision weighing control even during high-speed continuous operation. The ultra-low error accuracy effectively reduces material loss, improves product consistency, and helps enterprises reduce production costs and enhance product market competitiveness.

Key Product Advantages

1. Ultra-High Weighing Precision, Zero Waste

Different from traditional single-head weighing equipment with large errors, the 14-head combination weigher independently calculates and matches materials through multiple weighing units, with the accuracy controlled within ±0.3-1g. It effectively avoids excessive material filling or insufficient weighing, ensures consistent net weight of each package, reduces material waste, and improves product qualification rate to over 99%.

2. High-Speed Continuous Production, High Yield

The maximum operating speed reaches 90 bags per minute, realizing efficient and uninterrupted automatic packaging. Compared with semi-automatic and manual packaging lines, it greatly improves production efficiency, meets the large-scale production demand of medium and large food factories, and effectively shortens the production cycle and improves enterprise output value.

3. Full-Automatic Integrated Operation, Labor Saving

The whole production line from feeding, lifting, weighing, packaging to finished product output is fully automated, realizing unmanned continuous operation. It reduces the dependence on manual labor, saves labor costs for enterprises, and avoids product pollution and weighing errors caused by manual operation, ensuring standardized and hygienic production.

4. Stable Operation & Wide Compatibility

The modular integrated structure design makes the equipment operate stably with low failure rate and long service life. It is compatible with various granular nut products and snack foods, including mixed nuts, single nuts, dried fruits and other irregular granular materials, with strong versatility and wide application range.

5. Food-Grade Safety & Easy Maintenance

All parts in contact with materials are made of food-grade stainless steel, which is corrosion-resistant, easy to clean, and meets international food safety production standards. The equipment structure is optimized for easy disassembly and maintenance, reducing daily maintenance time and cost.

Application Scope

This automatic multi-nut weighing and packaging conveyor line is specially tailored for the nut and snack food processing industry, widely applicable to quantitative packaging of various products:

• Various single nuts: cashews, almonds, walnuts, pistachios, hazelnuts, pine nuts, etc.

• Mixed nut combinations and nut snack packs

• Dried fruits, granular snacks and other similar granular food products

It is the preferred automatic packaging equipment for food processing factories, nut production enterprises and snack food manufacturing plants, supporting customized packaging production of different specifications.

Production Line Working Process

1. Automatic Feeding: The independent vibrating feeding plate evenly outputs bulk nut materials to ensure stable and continuous material supply.

2. Material Lifting: The bucket elevator vertically transports materials to the feeding port of the combination weigher.

3. Precision Weighing: The 14-head combination weigher intelligently matches and weighs materials to complete quantitative distribution.

4. Automatic Packaging: The vertical packaging machine completes bag making, filling, sealing and cutting of materials.

5. Finished Product Conveying: The conveyor line outputs the finished packaged products to realize continuous assembly line operation.
