How to Choose the Right Steam Vacuum Capping Machine for Your Production Line
Steam vacuum capping machines are widely used in the food industry for sealing glass jars containing products such as chili sauce, honey, jam, peanut butter, fruit preserves, and pickled vegetables. By injecting steam before capping, these machines create a stable vacuum inside the container, helping extend shelf life and maintain product quality.
However, many buyers face a common question:
Which steam vacuum capping machine is right for my production line?
This guide compares the MR5D30A, MR5D30B, and MR5D30D models to help you make the right decision.

Overview of the MR5D30 Series
The MR5D30 Series is designed for automatic vacuum sealing of glass jars with 3-lug, 4-lug, 6-lug, and twist-off caps.
All three models share the same core performance:
- Production Capacity: 80–150 bottles/min
- Cap Diameter: Φ30–90 mm
- Bottle Diameter: Φ30–100 mm
- Bottle Height: 65–260 mm
- Steam Pressure: ≤0.4 MPa
- Maximum Vacuum Level: 67 kPa (502 mmHg)
The main differences are the machine structure and control system.
Not sure which model fits your production line?
Our engineers can recommend the most suitable steam vacuum capping machine based on your jar size, cap type, production capacity, and factory layout.
