Automatic Granule Pre-made Pouch Packaging Machine (PBP-G Series) - Advanced Automated Solution

The Automatic Granule Pre-made Pouch Packaging Machine (PBP-G Series) is an advanced automated solution designed for the precise packaging of granular products such as nuts, dried fruits, grains, and pet food. Perfectly suited for deep food processing factories and industrial agricultural lines, this machine streamlines operations with automatic feeding, high-precision combination weighing, and rapid heat sealing. Featuring a robust, corrosion-resistant SUS304 stainless steel construction, the PBP-G series ensures long-term durability in high-frequency environments with a throughput of up to 60 bags per minute and an intelligent no-bag detection system that significantly reduces material waste.

I. Product Overview & Use Scenarios

Widely applicable for automated packaging of granular materials such as nuts, dried fruit, candy, biscuits, grains, pet food, puffed food, plastic granules, and small hardware parts. Suitable for deep food processing factories, primary agricultural processing, and industrial packaging lines, it achieves full-automatic bag feeding, coding, bag opening, high-precision combination weigher or cup filling, automatic heat sealing, and product output through an intelligent PLC control system.

II. Core Advantages

• Multi-Model Adaptability: Available in PBP-G200, PBP-G250, and PBP-G300 models to match production requirements for different granule sizes and bag dimensions.
• High-Precision Metering: Equipped with a highly sensitive combination weigher or volumetric cup metering device to effectively control filling weight errors and reduce material spillage or under-filling.
• Anti-Waste Design: Features an intelligent detection system that automatically stops filling and triggers an alarm when no bag is detected, the bag fails to open, or the seal is defective.
• Robust Structure: The main body is constructed from high-quality SUS304 stainless steel, which is corrosion-resistant, durable, and compact for long-cycle production.
• Rapid Changeover: Equipped with a quick-adjustment mechanism that allows for fast changes to the clamp width, enabling quick transitions between different product specifications.

IV. Workflow

1. Automatic Bag Feeding: The automatic bag feeder transfers the pre-made bag to the rotary table clamps.
2. Coding: Automatically completes the printing of production date and batch codes on the bag surface.
3. Bag Opening Detection: The bag mouth is opened via vacuum suction cups; sensors perform real-time detection before proceeding.
4. Granule Filling: The metering device precisely dispenses the quantified granules into the bag.
5. Heat Sealing: The double-layer heating device completes the heat sealing of the bag mouth, ensuring a tight and smooth seal.
6. Cooling & Discharge: The sealing area is cooled and set, and the finished product is discharged smoothly via a conveyor belt.

V. Frequently Asked Questions (FAQ)

Q: Can the machine package granules of different shapes?
A: Yes, our system has excellent adaptability to granule shapes. If the material is fragile like potato chips, we can lower the discharge height of the elevator to reduce the breakage rate.

Q: How long does it take to change to different bag sizes?
A: This series is equipped with automatic or manual quick-adjustment handles, usually allowing a skilled operator to complete the bag type changeover within 10 to 20 minutes.
