High-Vacuum Jar Capping Machines
Engineered exclusively for glass jars and lug/twist-off caps. Featuring our patented mold-free adjustment technology for rapid changeovers. Achieve deep, airtight vacuum sealing to dramatically extend your food product’s shelf life.
Overcoming Jar Capping Challenges
Challenge 1: Costly & Slow Mold Changes
Traditional
Switching jar sizes requires purchasing expensive, custom-machined starwheels and molds, causing severe production downtime.
Tengzhuo Solution: Mold-Free Adjustment
Our proprietary multi-format clamping mechanism allows operators to adjust width via handwheels—zero molds required.
Challenge 2: Poor Vacuum & Food Spoilage
Traditional
Inadequate negative pressure leads to oxidation, severely reducing the shelf life of sauces and premium tonics.
Tengzhuo Solution: Deep Vacuum Chamber
Equipped with heavy-duty vacuum pumps to create a fully enclosed, high-negative-pressure environment for a perfect hermetic seal.
Challenge 3: Glass Breakage
Traditional
Rigid mechanical capping heads apply excessive force, crushing delicate glass threads during the tightening process.
Tengzhuo Solution: Flexible Capping Claws
Pneumatic or servo-driven claws apply precise, gentle torque to securely fasten lug caps without damaging the glass.
Advanced Engineering for Vacuum Sealing
Zero Leakage Environment
The capping process occurs within a fully sealed chamber. Operators can precisely adjust the negative pressure to meet the strictest food preservation standards.
1-Minute Changeovers
The universal bottle clamping system adapts to various jar diameters and heights instantly, completing line changeovers in just one minute.
Hot-Fill Compatibility
For specific hot-filling processes, we offer optional steam injection modules that flush the headspace before capping, creating an immediate vacuum upon cooling.
Washdown Ready 304/316 SS
Built to withstand highly corrosive environments containing salt and acidic sauces. The entire frame is constructed from thickened stainless steel for direct water washdowns.

Frequently Asked Questions
No. The intense negative pressure required for deep vacuum sealing will cause standard PET plastic bottles to collapse and deform. This machine is exclusively designed for glass jars and high-rigidity specialized containers.
Because we utilize a patented mold-free adjustment mechanism, the machine can theoretically accommodate an infinite number of jar sizes within its specified width and height range, without requiring you to buy extra parts.
Yes. The vacuum pressure can be precisely adjusted via the touchscreen interface and monitored on the built-in vacuum gauge, allowing you to set the perfect negative pressure for different food preservation needs.
Yes. Depending on your hot-filling process requirements, we can equip the machine with an optional steam injection module to flush the headspace and create a vacuum seal as the product cools.
