Description
The ZONESUN ZS-AFK120 Automatic Double-Head Vacuum Can Seamer is designed for sealing metal cans used for milk powder, infant formula, nutritional powder, coffee powder, protein powder and other dry products. The machine integrates automatic lid feeding, precise can positioning, vacuum treatment and double-head seaming in one continuous process.
It supports both vacuum sealing and vacuum-nitrogen sealing modes. With a double seaming-head structure, automatic lid feeding system and synchronized conveyor, the ZS-AFK120 is suitable for medium-to-high-value powder packaging lines that require stable airtight sealing, low residual oxygen and continuous production.

Applications
Ideal for vacuum and vacuum-nitrogen sealing of the following powdered products in cans or jars:
- Milk powder & infant formula
- Nutritional powder & health supplements
- Coffee powder & instant beverages
- Protein powder & sports nutrition
Suitable for dairy, food, and nutritional product packaging lines requiring high airtightness, low residual oxygen, and extended shelf life.
Component Details
Intelligent Control Panel
Controls sealing speed, vacuum time, nitrogen flushing duration, and other parameters for precise and stable operation with easy monitoring of production status.
Double Lid Feeder
Stores up to 200 lids and feeds them continuously and accurately to the sealing station, ensuring uninterrupted production without frequent manual lid loading.
Vacuum Sealing Chamber
Performs vacuuming and nitrogen flushing simultaneously with seaming, achieving residual oxygen under 3% in vacuum-nitrogen mode for maximum product freshness and shelf life.
Can Positioning Device
Accurately positions and holds cans during the vacuuming and seaming process, preventing movement and air leakage for consistent, airtight seal quality.
Conveyor Belt & SUS304 Construction
Customizable conveyor belt transports cans smoothly through the sealing process, while the SUS304 stainless steel body ensures food-grade hygiene, corrosion resistance, and long service life.
Vacuum Sealing vs Vacuum-Nitrogen Sealing
Vacuum sealing removes air from the can before seaming and is suitable for applications where reduced internal pressure and airtight closure are required. Vacuum-nitrogen sealing combines vacuum treatment with nitrogen flushing before final seaming, making it suitable for powder products where lower residual oxygen is required.
Best-Suited Packaging Applications
The ZS-AFK120 is mainly used for rigid cans and jars with metal lids in powder packaging lines. Typical applications include milk powder, infant formula, nutritional powder, protein powder, coffee powder and other dry products that require vacuum or vacuum-nitrogen can seaming.
Automatic Lid Feeding and Double-Head Seaming
The automatic lid feeding system continuously supplies lids to the sealing station, while the double-head seaming structure supports continuous can processing. This configuration reduces manual lid placement and is suitable for production lines where stable sealing speed and repeatable can positioning are important.

Frequently Asked Questions
What is the difference between vacuum sealing and vacuum-nitrogen sealing?
Vacuum sealing removes air before the can is seamed. Vacuum-nitrogen sealing adds a nitrogen-flushing step after vacuum treatment and before final sealing.
Can the ZS-AFK120 seal milk powder cans?
Yes. Milk powder and infant formula cans are typical applications for this machine when the can and lid dimensions match the required sealing range.
Does the machine feed lids automatically?
Yes. The ZS-AFK120 is equipped with an automatic lid feeding system with a listed capacity of up to 200 lids.
What can diameter can the machine handle?
The listed sealing diameter range is Φ70–127 mm, with container height from 100–200 mm.
Can it be connected to a powder filling line?
Yes. The machine can be integrated with compatible powder filling, conveying, labeling and downstream packaging equipment as part of a complete can packaging line.
Should can and lid samples be provided before production?
Yes. Providing actual can and lid samples helps confirm the seaming tooling, positioning structure and lid feeding setup.
Need Help Confirming the Can Seaming Setup?
