Product Overview

The automatic Nut Mixing Weighing Packaging Production Line is a customized integrated packaging solution specially designed for mixed nut packaging requirements. Tailored for four-type mixed nut packaging with a standard net weight of 200g per bag, this fully automated production line realizes full-process automation from material lifting, vibration feeding, precise mixing weighing to quantitative bagging and packaging.

Adopting a combined weighing system of 32-head combination weigher and 4-head linear weigher, matched with multi-stage vibration feeding equipment and an eight-station bag-given packaging machine, the line achieves stable high-speed operation while ensuring ultra-high weighing accuracy. It effectively solves the problems of uneven mixing, large weighing error and low production efficiency in traditional manual or semi-automatic nut packaging, and is an ideal automated packaging equipment for food factories, nut processing enterprises and snack production bases.

Complete System Configuration

This nut mixing packaging production line adopts a modular combined structure, with reasonable equipment matching and smooth production workflow. The complete system configuration is as follows:

• 5 Sets of Lifting Machines with Vibrating Feeders: Responsible for automatic vertical lifting of bulk nut raw materials, equipped with vibration feeding function to ensure uniform and continuous material conveying, avoid material accumulation and blockage, and provide stable material supply for the subsequent weighing system.

• 4 Sets of Transition Vibrating Feeders: Play the role of material buffer and uniform distribution, finely adjust the material conveying speed and flow, ensure the four types of nuts are fed stably in proportion, and lay a foundation for accurate mixing and weighing.

• 1 Set of 32-Head Combination Weigher: Core high-precision weighing equipment, suitable for multi-material mixed weighing, with fast data calculation and high-precision metering capabilities, realizing rapid and accurate batching of mixed nuts.

• 1 Set of 4-Head Linear Weigher: Assist in quantitative fine-tuning of single nut materials, cooperate with the combination weigher to calibrate the proportion of various nuts, effectively improve the uniformity of mixed materials and further optimize weighing accuracy.

• 1 Set of Eight-Station Bag-Given Packaging Machine: Complete automatic bag taking, bag opening, filling, sealing and output of finished products. The eight-station design realizes cyclic continuous operation and greatly improves packaging efficiency.

Core Technical Specifications

This production line is professionally calibrated for 200g mixed nut packaging scenarios, with stable performance, accurate metering and efficient production, and the core technical parameters are standardized as follows:

Key Product Advantages

High-Precision Weighing & Uniform Mixing

The dual weighing system of 32-head combination weigher and 4-head linear weigher realizes dual calibration of mixed materials, with a weighing error controlled within ±1.5g. The multi-stage vibration feeding structure ensures uniform mixing of four nuts, avoiding uneven ingredient ratio of finished products.

Stable High-Speed Production

The eight-station cyclic bagging mechanism cooperates with continuous feeding and rapid weighing system, achieving a stable output of 25 bags per minute. The whole line runs smoothly without material jamming or shutdown failure, greatly improving enterprise production capacity.

Full-Process Automatic Operation

Integrates material lifting, feeding, mixing, weighing, bagging, sealing and finished product output. It supports 24-hour continuous operation, reduces manual intervention, saves labor costs, and improves production standardization.

Wide Compatibility & Customization

The production line is suitable for all kinds of granular nut mixed packaging. On the basis of the standard 200g specification, it can also be adjusted and customized according to customer’s different weight and material mixing ratio requirements.

Food-Grade Safe Design

All material contact parts adopt food-grade stainless steel materials, which are corrosion-resistant, easy to clean, and meet international food safety production standards. The equipment has a closed structure to prevent dust and material pollution.

Low Maintenance & High Durability

Modular assembly design, simple equipment structure, convenient daily maintenance and parts replacement. The core components are made of high-quality materials, with long service life and low operating failure rate.

Application Scenarios

This automatic nut mixing weighing packaging line is widely applicable to the quantitative packaging of various mixed granular nut products, and is perfectly suitable for medium and large food processing factories, nut production enterprises, snack food manufacturers and food packaging processing plants. It is mainly used for mixed packaging of various nuts such as mixed daily nuts, baked nuts, gift box nuts and casual snack nuts, helping enterprises realize standardized and large-scale automated production.

Working Process

1. Material Lifting & Feeding: The lifting machine transports bulk nut raw materials to the vibration feeder, and the vibrating device realizes uniform and continuous material output;

2. Transition Distribution: Four transition vibrating feeders separately convey different types of nuts to the weighing system according to the set proportion;

3. Precision Mixing & Weighing: The 32-head combination weigher and 4-head linear weigher work together to complete high-precision batching and weighing of 200g mixed nuts;

4. Automatic Bagging & Sealing: The eight-station bag-given machine automatically completes bag taking, opening, material filling, heat sealing and cutting;

5. Finished Product Output: The packaged finished nut products are automatically output, realizing continuous cyclic production.
