Automatic Granule Premade Pouch Packing Machine

Product Overview

This automatic premade pouch packing machine is designed for weighing and packing free-flowing granular products into ready-made bags. The upper three-head weighing section uses controlled vibration to portion the material, while the lower packaging section handles the prepared pouch, receives the measured product, seals the opening, and discharges the finished package.

The machine supports a confirmed filling range of 10–500 g and can process several premade pouch formats, including three-side-sealed bags, four-side-sealed bags, back-sealed bags, stand-up pouches, zipper stand-up pouches, eight-side-sealed bags, and shaped pouches. Its touch-screen interface and PLC control system allow operators to set and manage the packaging process from a centralized control panel.

The weighing and packaging sections use a split structure. They can operate together as a complete packing system or be configured separately according to the production arrangement. This design is suitable for snack factories, grain and seed processors, pet food producers, coffee roasters, contract packers, and small-to-medium production facilities.

Final suitability depends on product size, flowability, bulk density, surface condition, and required filling accuracy. Sticky, oily, highly dusty, or irregular materials should be tested before the machine configuration is confirmed.

Applications

This machine is suitable for dry, free-flowing granular products that can be discharged consistently by a vibratory weighing system. The product should fall smoothly into the premade pouch without severe sticking, bridging, excessive dust generation, or irregular blockage.

This machine is suitable for:

• Peanuts
• Mixed nuts
• Sunflower seeds
• Pumpkin seeds
• Coffee beans
• Candy
• Chocolate beans
• Rice
• Beans and pulses
• Cereal granules
• Roasted grains
• Dried fruit pieces
• Pet food granules
• Seasoning granules
• Small snack pellets

A material test is recommended for fragile products, sticky dried fruit, oily nuts, products containing excessive powder, highly irregular pieces, or materials that may bridge inside the hopper.

Main Features

1. Three-Head Vibratory Weighing

Three weighing heads portion granular products through controlled vibration, supporting multi-head operation within the confirmed 10–500 g filling range.

2. Gentle Granule Handling

The vibratory feeding principle transfers products without relying on an auger, helping reduce mechanical compression when handling nuts, seeds, candy, coffee beans, and similar granules.

3. Premade Pouch Packaging

The machine fills ready-made bags rather than forming bags from roll film, making it suitable for retail pouches with different shapes and printed designs.

4. Multiple Pouch Formats

The documented bag options include three-side seal, four-side seal, back seal, stand-up, zipper stand-up, eight-side seal, and shaped premade pouches.

5. PLC-Controlled Operation

The PLC coordinates weighing and packaging actions, while the touch-screen interface provides centralized access to production settings and operating controls.

6. Split Machine Structure

The weighing and packaging sections are constructed as separate modules that can be used together or configured independently according to the production requirement.

7. Compact Floor Space

The compact machine arrangement combines the weighing section above the pouch packaging unit, helping reduce the required installation area in smaller workshops.

8. Adjustable Packaging Range

The machine supports premade pouches from 120 to 300 mm long and 100 to 200 mm wide within the documented specification.

9. Compressed-Air Operation

The packaging section operates with a confirmed working air-pressure range of 0.7–0.8 MPa, requiring a suitable external compressed-air supply.

Working Principle

Granular material is first loaded into the upper feeding and weighing section. Controlled vibration moves the product toward the three weighing heads, where the required portion is measured according to the selected setting.

At the same time, the packaging section positions a premade pouch for filling. Once the weighing cycle is complete, the measured product is discharged through the central outlet and guided into the prepared bag. The pouch is then processed by the packaging section, sealed, and released as a finished package.

The PLC coordinates the weighing and packaging sequence, while the touch screen allows the operator to manage relevant settings. Because the filling and packaging sections use a split design, the two modules can operate as one complete system or be arranged separately where required.

Actual performance depends on product flowability, bulk density, pouch material, pouch opening condition, and filling weight.

Process Flow:

Material Feeding → Vibratory Distribution → Three-Head Weighing → Premade Pouch Positioning → Filling → Pouch Sealing → Finished-Package Discharge

Machine Details

1. Product Feeding Hopper

The upper hopper stores granular material and supplies it to the vibratory distribution section. Product loading should remain controlled to maintain stable weighing performance.

2. Three-Head Weighing System

Three individual weighing heads measure product portions before discharge. The system is designed for granular materials within the specified 10–500 g range.

3. Vibratory Feeding Unit

The vibratory feeding section moves material toward the weighing heads through controlled vibration, helping regulate product flow without using a screw-feeding mechanism.

4. Central Discharge Chute

After weighing, the measured product is released through the central chute and guided into the premade pouch positioned below the filling section.

5. Premade Pouch Handling Section

This lower section receives and positions the selected ready-made pouch during the filling and packaging cycle. Final compatibility depends on the pouch dimensions and construction.

6. Pouch Sealing Section

After filling, the sealing section closes the pouch opening. Sealing settings must be matched to the customer’s actual pouch material and thickness.

7. Touch-Screen Interface

The front-mounted touch screen provides an operating interface for managing weighing and packaging settings and observing the machine’s operating status.

8. PLC Control System

The PLC coordinates the movement and timing of the weighing, filling, pouch-handling, and sealing sections during the automatic operating cycle.

9. Transparent Safety Guard

The machine image on page 1 shows a transparent front protection area around the lower packaging mechanism, allowing operation to be observed while limiting direct access.

10. Mobile Machine Base

Caster wheels visible on the machine base support positioning during installation, workshop adjustment, and cleaning around the equipment.

Technical Parameters

Packaging & Shipping

The supplied document does not confirm the final export packing method, packed dimensions, gross weight, delivery time, or shipping terms. These details should therefore be confirmed after the customer selects the machine configuration, pouch format, power specification, and any required accessories.

Before shipment, the machine configuration should be checked against the confirmed order using the customer’s actual granular product and premade pouch samples where available. The weighing range, pouch dimensions, sealing compatibility, compressed-air requirements, and electrical specification should be verified before dispatch.

The final packing method, shipping dimensions, and gross weight will be confirmed according to the selected machine configuration. Freight, customs clearance, destination charges, import duties, and local delivery arrangements should be agreed separately with the buyer.
