Vacuum Capping Systems: Oxygen-Free Sealing for Sensitive Products
LOCUS ROBOTICS engineers specialized vacuum cappers that create oxygen-free seals for glass jars with metal Twist-Off lids — the superior alternative to pasteurization or nitrogen flushing for food preservation. Ideal for oxygen-degradable foods/chemicals and nutraceuticals.
| Preservation Method | Shelf-Life Extension | Equipment Cost | Ideal Products |
|---|---|---|---|
| Vacuum Capping | 2-3X | $$ | Vegetables, preserves, juices |
| Nitrogen Flushing | 1.5-2X | $$$ | Powders, snacks |
| Pasteurization | 1.5X | $$$$ | High-acid foods |
| Model | Chambers | Capacity | Output | Key Feature |

Extends coffee shelf life from 6 to 24 months by reducing O₂ to <0.05%.
Typical Small-Batch Setup:
Piston Filler → LVCM-100 Vacuum Capper → Semi-Auto Labeler
(Output: 42 jars/min | Footprint: 6m²)
Automated Production Line:
Auger Filler → LVCM-100 Multi-Jar Capper → Rotary Labeler
(Output: 180 jars/min | ROI: <12 months)
| vs. Standard Cappers | LOCUS Custom Edge |
|---|---|
| Standard tooling only | Custom adapters for ANY Twist-Off lid (30-120mm) |
| Fixed jar size capacity | Adjustable bell jars (50ml-3L jars on same unit) |
| Limited vacuum control | Precision O₂ sensors (50-300mbar adjustable) |
Our LVCM-100 achieves 99.2% seal integrity on irregular homemade-style jars – impossible with off-the-shelf systems.
