Say Goodbye to Fragmented Processes and Manual Intervention: Create an Ultra-Fast Automated Experience for Granule Canning

The Complete Granule Canning Production Line (integrating Can Unscrambling $\rightarrow$ Conveying $\rightarrow$ Automatic Weighing & Dosing $\rightarrow$ Can Seaming $\rightarrow$ Labeling $\rightarrow$ Can Collecting) is an industrial-grade, high-efficiency automation system built specifically to solve granule and block product canning pain points, such as slow manual feeding, low weighing accuracy, excessive dust, weak seals, and bubbles during labeling.

LANTU Machinery introduces tailored, full-line automated granule canning solutions. Utilizing precision chain-plate conveying, multi-head computer combination scales, high-precision vacuum/nitrogen-flushing can seamers, and automated labeling heads, the line operates across six core stations (1. Can Unscrambling/Feeding $\rightarrow$ 2. Air Jet Can Cleaning $\rightarrow$ 3. Automatic Weighing & Dosing $\rightarrow$ 4. Automatic Cap Feeding & Seaming/Crimping $\rightarrow$ 5. Precision Positioning Labeling $\rightarrow$ 6. Automatic Can Collecting/Packing). It functions like an expert dedicated to canning and packaging. Whether processing round cans, square cans, paper tubes, PET jars, or tinplate cans, it realizes end-to-end integration: automatic unscrambling, dust removal, precise dosing, tight seaming, clean labeling, and finished container collection with zero weighing errors, zero leakage, and no manual contact required.

As a direct source packaging machinery manufacturer, LANTU Machinery makes this complex automatic unscrambling, air cleaning, scale synchronization, optical positioning, auto-capping/seaming, and smart labeling process as intuitive as using a smartphone. Operators simply adjust parameters on the central PLC touchscreen and load empty cans and bulk material into the unscrambler and hopper. The production line automatically manages can fetching, weighing, dosing, seaming, and labeling to deliver market-ready products. Accommodating a wide range of container diameters and heights (e.g., diameter 50mm to 150mm, height 50mm to 200mm), this line drastically shortens packaging cycles while saving labor, time, and operating costs.

Choosing a reputable source manufacturer is crucial for your return on investment. LANTU Machinery’s mature line-control and automatic seaming/labeling technologies deliver high reliability and material efficiency to keep your canning line running without interruption.

Precision Positioning Labeler: Equipped with high-sensitivity optical sensors and servo labeling heads supporting single, double, or wrap-around positioning labeling without bubbles or wrinkles.

3.Central Control & Safety Protection System

Siemens / Mitsubishi PLC Bus Central Controller: Industrial-grade multi-core CPU provides centralized line control, full-line status monitoring, anti-interference capabilities, and multi-language support.

No Can No Dosing / No Cap No Seaming Protection: Real-time sensors monitor containers and caps. Operations automatically pause if containers or caps are missing, preventing material waste and equipment contamination.

Fully Enclosed Safety Guarding: Key line stations feature transparent safety doors that instantly stop operation when opened, meeting GMP and food/pharma hygiene standards while protecting operators.

Technical Specifications

To meet the diverse production needs of various factories regarding container materials (PET, Tinplate, Paper Cans), dimensional ranges, and packaging speeds, Lanto Machinery offers two core line configurations for the Automatic Granule Canning Line:

Note: Actual line speed depends on material flowability, dose weight, container dimensions, and lid type. Lanto Machinery provides custom engineering for complete turnkey packaging lines.

Complete Granule Canning Line Workflow

Station 1 (Can Unscrambling / Feeding): Bulk empty cans are loaded into the unscrambler, aligned into a single file by rotary or directional mechanisms, and fed onto the main conveyor.

Station 2 (Air Cleaning / Dust Removal): Cans enter the cleaning station where high-pressure ionized air removes static and dust while a vacuum exhaust extracts debris.

Station 3 (Weighing / Dosing): The multi-head scale weighs material with precision, container stoppers position empty cans, and nozzles lower to deliver target charges.

Station 4 (Auto Cap Feeding / Seaming): Caps are sorted and placed on container mouths, where seaming rollers execute high-pressure crimping (or optional vacuum nitrogen sealing).

Station 5 (Precision Labeling / Coding): Containers enter the labeling area, where pressure rollers and rotation mechanisms apply labels. Optional inkjet/laser printers apply codes on can bases or walls.

Station 6 (Finished Can Collection / Packing): Fully labeled cans exit onto a buffering collection turntable for manual casing or integration with downstream automated case packers.

Key Factors to Consider When Purchasing a Granule Canning Line

To select the ideal production line configuration, evaluate the following key purchasing metrics:

Target Output (cans/min):

20–40 cans/min: Single filling head + standard seaming and labeling line.

40–80 cans/min: Dual/multi-head scale filling + high-speed seaming and labeling line.

Container Material & Dimensions: Define maximum/minimum container diameter (e.g., 65mm–100mm) and height to customize unscrambler plates, stopper blocks, and seaming rollers.

Cap Types: Plastic caps, easy-open lids, aluminum peel-off ends, or screw caps (determines cap sorting and seaming/capping mechanisms).

Preservation & Special Functional Needs: Determine requirements for vacuum extraction, nitrogen flushing, bottom coding, sleeve labeling with shrink tunnels, or weight checkweighing/rejection.

Frequently Asked Questions (FAQ)

Q1: Can the production line handle containers of different diameters and heights?

A: Yes. Our line features modular adjustable designs. Height adjustments are made via handwheels or motorized lifts, while diameter changes require only changing star wheels or guide rails, making transitions simple.

Q2: If the material produces dust, will it affect sealing and line cleanliness during dosing?

A: No. We install dust shrouds and negative-pressure vacuum extraction at the dosing nozzles to capture airborne dust during drop, keeping container rims clean for tight seals.

Q3: Can the line flush nitrogen gas to extend product shelf life after seaming?

A: Fully supported. We can integrate a vacuum nitrogen sealing system at the seaming station. Air is evacuated before high-purity nitrogen is injected, reducing residual oxygen levels to below 1% to extend product shelf life.
