Automatic Multi-Format Granule Packing Machine

Product Overview

This automatic granule packing machine is a vertical form-fill-seal system designed for small-dose, free-flowing granular products. It can produce triangular three-dimensional sachets, conventional three-side-seal bags, and back-seal bags according to the selected packaging setup.

Granular material is supplied to the upper hopper and measured by a volumetric cup system. Roll-fed packaging film is drawn through the forming section, shaped into the selected bag style, and filled with the measured product. The machine then completes heat sealing, cutting, finished-bag counting, and discharge. An optional coding device can be added when production dates or batch numbers are required.

The documented configuration uses touch-screen operation, PLC control, stepper-motor bag-length control, color-mark detection, and PID temperature regulation. Its 1–100 g filling range makes it suitable for confectionery, food ingredients, beverage granules, small non-hazardous industrial granules, and other compatible products.

The machine is intended for food factories, confectionery producers, contract packers, and manufacturers requiring several small sachet formats without installing separate packaging machines for every bag style.

Applications

This machine is suitable for dry, free-flowing granular materials that can be measured consistently by volumetric cups. Product size, bulk density, surface condition, moisture content, and flowability should be checked before the cup size and filling configuration are finalized.

This machine is suitable for:

• Gummy candy
• Chocolate beans
• Malted chocolate balls
• Granulated sugar
• Salt
• Seasoning granules
• Instant beverage granules
• Coffee granules
• Tea granules
• Granulated sweeteners
• Small cereal pellets
• Desiccant beads
• Bath salt granules
• Cosmetic beads
• Other non-hazardous free-flowing granules

A material test is recommended for sticky candy, oily products, fragile granules, irregular pieces, high-moisture materials, products containing excessive powder, or granules that may bridge inside the hopper.

The supplied document specifically confirms gummy candy, chocolate beans, and malted chocolate balls as representative applications.

Main Features

1. Multiple Sachet Formats

The machine supports triangular three-dimensional sachets, three-side-seal bags, and back-seal bags, allowing different package presentations to be produced with the appropriate machine setup.

2. Automatic Packaging Cycle

Material dosing, bag forming, filling, heat sealing, cutting, counting, and finished-bag discharge are completed through one coordinated automatic operating process.

3. Volumetric Cup Dosing

The volumetric cup system measures free-flowing granules by volume and releases each portion into the formed sachet during the packaging cycle.

4. Adjustable Bag Dimensions

Bag length can be adjusted through the control system, while compatible bag width and format depend on the selected forming and sealing configuration.

5. PLC and Touch-Screen Control

The touch-screen interface and PLC coordinate material dosing, film feeding, bag-length control, sealing, cutting, alarms, and other packaging functions.

6. Stepper-Motor Film Control

A stepper motor controls packaging-film movement and bag length, supporting repeatable film feeding for the selected sachet dimensions.

7. Color-Mark Detection

The documented color-mark sensor can track registration marks on printed film and coordinate the cutting position with the package artwork.

8. PID Temperature Regulation

The intelligent temperature controller uses PID regulation to manage heat-sealing temperature and reduce temperature variation during continuous production.

9. Optional Batch Coding

A coding device can be configured when the customer requires production dates, batch numbers, or other traceability information on the package.

10. Compact Vertical Structure

The vertical forming and filling arrangement integrates dosing, bag making, sealing, and cutting within a relatively compact machine footprint.

Working Principle

Granular product is loaded into the upper hopper and transferred to the volumetric cup dosing system. The selected cup measures a preset volume and prepares the product for discharge.

Packaging film is unwound and advanced by the film-feeding system. The forming mechanism shapes the film according to the selected triangular, three-side-seal, or back-seal package configuration. When the partially formed bag reaches the filling position, the measured granules are released through the filling tube.

The sealing mechanism closes the package using controlled heat. The stepper-driven film system advances the material to the preset bag length, while the color-mark sensor can coordinate printed-film positioning. The cutting unit separates the finished sachet, and the counting system records the completed output before discharge.

Coding can be added as an optional stage when required.

Process Flow:

Material Feeding → Volumetric Cup Dosing → Film Unwinding → Bag Forming → Filling → Heat Sealing → Film Positioning → Cutting → Counting → Discharge

Machine Details

1. Material Hopper

The upper hopper stores free-flowing granular product and supplies it to the measuring section. Stable material flow is important for consistent volumetric dosing.

2. Volumetric Cup System

The measuring cups portion the product by volume. Cup specification should be selected according to the product’s bulk density and required filling weight.

3. Film Unwinding System

The roll-film holder and feeding mechanism continuously supply packaging material to the forming and sealing section.

4. Bag Forming Section

The forming structure shapes the roll film into the selected triangular three-dimensional, three-side-seal, or back-seal package.

5. Filling Tube

The filling tube guides the measured granules from the cup-dosing system into the partially formed sachet.

6. Heat-Sealing Unit

The sealing system applies controlled heat to close the packaging film according to the selected bag format and film structure.

7. Film-Pulling Mechanism

The stepper-driven pulling system advances the packaging film according to the preset bag length and operating cycle.

8. Cutting System

The cutting mechanism separates each completed package after filling and sealing, creating individual finished sachets.

9. Touch-Screen Control Panel

The interface allows operators to manage bag length, operating functions, temperature settings, production controls, and machine status.

10. Coding Device — Optional

An optional coding device can be installed for printing production dates, batch information, or other required package markings.

Technical Parameters

Packaging & Shipping

The supplied quotation lists wooden-case packing as a separately priced item rather than confirming that it is automatically included with every order. The final packaging arrangement should therefore be confirmed in the sales contract.

Before shipment, the machine should be tested using the buyer’s approved granular product, target filling weight, sachet format, packaging film, bag dimensions, and printed-film artwork. The volumetric cup, film feeding, forming system, heat sealing, cutting, color-mark tracking, counting, and optional coding functions should be checked against the confirmed configuration.

Product-contact parts should be cleaned, while the film holder, control panel, sealing mechanisms, and moving components should be secured against transportation damage.

The final packing method, shipping dimensions, gross weight, and number of shipping packages will be confirmed according to the selected machine configuration.

FAQ

Q1: What products can this machine package?

The machine can package gummy candy, chocolate beans, malted chocolate balls, sugar, salt, seasoning granules, coffee granules, and similar dry, free-flowing products. Sticky, oily, fragile, dusty, or irregular materials should be tested before the volumetric cup and feeding configuration are confirmed.

Q2: What package styles can the machine produce?

The documented machine supports triangular three-dimensional sachets, three-side-seal bags, and back-seal bags. Final bag-format compatibility depends on the forming structure, sealing arrangement, bag dimensions, and packaging film selected for the confirmed machine configuration.

Q3: Can the machine switch between bag styles automatically?

The file name refers to one-button switching, but the technical description only confirms that three bag formats are available. The exact switching procedure, required mechanical adjustments, and whether forming parts must be replaced should be confirmed before this function is advertised.

Q4: Is the 1–100 g range suitable for every product?

The confirmed filling range is 1–100 g, but volumetric cups measure by volume. The actual usable weight range depends on product density, particle size, flowability, and cup capacity. Customer material testing is recommended before the final dosing specification is selected.

Q5: What information is required before ordering?

Please provide the product name, product photos or samples, particle dimensions, bulk density, target weight, bag style, bag width and length, film structure, film thickness, roll direction, printed artwork, required output, local voltage, and coding requirements.
