What is vertical granule packing machine?

Vertical granule packing machine is an automated packing equipment designed for granular materials (such as rice, nuts, candy, fertilizer, pet food, etc.). The equipment integrates multiple processes such as automatic metering, bag making, filling, sealing, and bag cutting of materials into one, greatly improving packing efficiency and consistency. Common vertical granule packing machine models include 320, 420, 520, 720, etc., where the model number mostly refers to the upper limit of the finished bag width (mm). The output corresponding to different models ranges from 30 to 70 bags per minute, which can meet the production needs of different scales. In terms of price, the basic equipment is about $4,000-$6,000, and the mid-to-high-end models with weighing combination scales or multi-function modules are between $10,000-$20,000. The price of customized solutions will be higher.

Technical parameters of vertical granule packing machine

Packing speed: The standard 420 model has a packing speed of 30-60 bags/minute. The specific speed is affected by material fluidity, bag size and feeding method.

Measuring accuracy: Usually combined with a weighing automatic metering system, the metering error is controlled within ±1% to ensure the consistency of the net content of each bag.

Bag size: The bag size range is 50-300mm in length and 80-200mm in width. It can support a variety of bag types such as pillow bags, gusset bags, and punching bags (some need to be customized).

Applicable film materials: Compatible with a variety of heat-sealing film rolls such as OPP/CPP, PET/PE, and nylon composite films. The width of the film roll must match the width of the bag and have good heat-sealing performance.

Power supply: The power of the equipment is generally 2-3KW, supporting 220V single-phase or 380V three-phase power supply, suitable for different industrial production environments.

Optional functions (high-end models): Optional color tracking, automatic coding/inking and nitrogen filling devices are available to achieve functions such as pattern positioning, batch information printing and food preservation.

What are the structural advantages of vertical granule packing machines?

The vertical granule packing machine has a compact and efficient structure, stable operation, and is widely used in automated packing in multiple industries. The following are the main advantages:

Compact structure and small footprint: The vertical design layout is reasonable and space-saving, especially suitable for small and medium-sized factories and production environments with limited space.

Gravity feeding and stable operation: The vertical film walking is combined with the natural falling path of the material, making the packing process smoother and effectively reducing operational problems such as blocking and bag jamming.

Strong functional integration: The vertical structure facilitates the integration of automatic weighing, coding, bag making, sealing, bag cutting and other modules to achieve continuous and efficient packing operations.

Bag shape is straight and seal is beautiful: the vertical forming mechanism makes the packaging bag shape more uniform and the seal is smooth, which improves the consistency of product appearance and enhances market competitiveness.

Easy to maintain and clean: the structure is clear, key parts are easy to inspect, and daily cleaning and maintenance are convenient, reducing downtime and maintenance costs.

Widely applicable industries: especially suitable for industries such as food, daily chemicals, and medicine that have high requirements for cleanliness and packing consistency, and have become an important part of the intelligent packaging system.

How to choose the suitable vertical granule packing machine?

Small production enterprises (start-ups, family factories, etc.)

Focus: low investment cost, simple operation, small footprint

Selection suggestions:

It is recommended to choose the 320 or 420 basic vertical granule packing machine, which is suitable for packing common granule products such as rice, nuts, feed, etc.;

The measuring cup or single bucket weighing system can be optional to meet general measurement needs;

The operation interface should be simple and friendly, and support less people on duty;

Within the budget range ($4,000-$6,000), give priority to mature brand entry-level models with stable structure and perfect after-sales service;

The film material and bag type should choose universal specifications for easy procurement and replacement.

Medium-sized production enterprises (regional brands, factory expansion)

Focus: efficiency improvement, product diversity, functional scalability

Selection suggestions:

It is recommended to use 420 or 520 high-speed models to meet the daily production capacity of 30-60 packages/minute;

Equipped with multi-head combination scales to improve measurement accuracy and adapt to different materials;

Optional auxiliary functions such as color tracking, automatic coding, exhaust holes, and corner formers;

The system should have a certain degree of scalability and can be connected to automated devices such as conveying and testing;

The budget range is recommended to be between $8,000-$15,000, taking into account both cost-effectiveness and functional upgrades.

Large-scale production enterprises (factory assembly lines, OEM)

Focus: high production capacity, automated whole-line docking, intelligent control

Selection suggestions:

It is recommended to use 520 or 720 high-speed vertical packaging machines, with a single machine capacity of 60-80 packages/minute;

Equipped with high-precision electronic weighing system, multi-language touch interface, and networking function, it can realize central control and remote monitoring;

A complete set of configurations includes feeder, automatic weighing, coding machine, metal detection, weight rejection, finished product conveyor belt, etc., to build a fully automatic packaging assembly line;

For industries with high requirements for packaging aesthetics and bag stability (such as food exports, medicine, and daily chemicals), nitrogen filling preservation, dust-proof structure, and clean protective cover can be added;

The budget range is generally $15,000-$30,000 or more, focusing on long-term stable operation and comprehensive operational efficiency.
