The VTOPS Steam Vacuum Capping Machine Series is designed for automatic vacuum sealing of glass jars with twist-off lug caps. By injecting steam into the container headspace before capping, oxygen is displaced and a natural vacuum is created as the steam cools and condenses. This process helps preserve product freshness, improve shelf life, and ensure reliable sealing quality.
The series is widely used for vacuum sealing glass jars containing chili sauce, honey, jam, peanut butter, tomato sauce, fruit preserves, sesame paste, pickled vegetables, and other food products. It can be integrated with bottle washing systems, filling machines, labeling machines, coding equipment, and carton packaging systems to create a complete automated production line.

Key Features
- Steam Vacuum Sealing Technology
Creates a stable vacuum inside glass jars to improve product freshness and shelf life. - Compatible with Multiple Cap Types
Suitable for 3-lug, 4-lug, 6-lug, and twist-off caps. - High Production Efficiency
Production speed up to 150 bottles per minute for continuous operation. - Food-Grade Construction Options
Available in carbon steel or stainless steel versions to suit different production environments. - Easy Operation
Choose between push-button control or PLC touch screen operation. - Easy Line Integration

Working Principle
- Filled jars enter the machine through the conveyor.
- Steam is injected into the headspace of the container.
- The steam displaces oxygen and air from the bottle.
- The cap is immediately applied and tightened.
- As the steam cools, it condenses and creates a vacuum.
- The sealed jars exit the machine and continue to downstream packaging processes.

Frequently Asked Questions
What is a steam vacuum capping machine?
A steam vacuum capping machine injects steam into a container before capping. As the steam cools and condenses after sealing, a vacuum is naturally created inside the jar.
What cap types can this machine handle?
The machine supports 3-lug, 4-lug, 6-lug, and standard twist-off caps commonly used for glass jars.
What products are suitable for vacuum capping?
Typical products include chili sauce, honey, jam, peanut butter, pickles, fruit preserves, tomato sauce, and other food products packed in glass containers.
Can the machine be integrated into a complete packaging line?
Yes. The machine can be integrated with bottle washing, filling, labeling, coding, and cartoning equipment to form a complete automated production line.
What is the difference between MR5D30A, MR5D30B, and MR5D30D?
All three models offer the same production capacity and vacuum sealing performance. The differences are mainly in machine construction and control systems:
- MR5D30A: Carbon steel construction + push button control
- MR5D30B: Stainless steel construction + touch screen control
- MR5D30D: Stainless steel construction + push button control
