1. Key Challenges in Jam and Sauce Packaging
Product viscosity, filling temperature, particle content and packaging dimensions influence equipment selection. The filling, capping and labeling stages also need to work at compatible speeds.
Filling Consistency
Changes in viscosity and temperature can affect product flow. Filling settings need to maintain the required quantity while limiting underfilling and product giveaway.
Drips and Jar Rim Contamination
Strings or drips can leave residue around the jar opening. Nozzle design and shut-off control should support clean filling and reliable closure application.
Products with Particles
Fruit pieces, seeds and other solids must pass through the product passages, valves and nozzles without unacceptable blockage or ingredient damage.
Manual Transfers
Moving jars between separate machines adds handling and can create queues. Coordinated conveying helps connect the packaging stages.
Jar and Lid Compatibility
Jar neck dimensions, lid profiles and sealing liners must suit the capping configuration and intended closure process.
Label Placement
Jar spacing, shape and surface condition affect label placement and adhesion. Hot or wet jars may need conditioning before labeling.
2. ZS-FAL180V9 Automatic Packaging Workflow
The line connects jar conveying, filling, cap sorting and feeding, steam vacuum capping and labeling through a coordinated conveyor system.
Glass Jar Conveying
Empty jars move toward the filling section. Conveyor guides and transfer points are adjusted for the jar dimensions. Manual loading or additional jar-feeding equipment should be specified in the final configuration.
Six-Head Servo Tracking Filling
Servo-driven piston pumps dispense measured quantities. Tracking nozzles follow the moving jars, coordinating product dispensing with container travel.
Cap Sorting and Feeding
The sorter organizes compatible lids and feeds them toward the capping section. The feeding mechanism must suit the lid dimensions and maintain the required operating rate.
Steam Vacuum Capping
Steam displaces air in the jar headspace before the closure is secured. Condensation during cooling helps create a vacuum inside the sealed jar.
Automatic Labeling
Filled and capped jars are spaced and positioned for label application. The labeling configuration should match the jar shape, label dimensions and required label position.
Optional Equipment Before and After the Main Line
Additional operations can be considered according to the production process and final packaging requirements.
| Position | Optional Equipment | Purpose |
|---|---|---|
| Before filling | Empty-jar cleaning and drying | Prepare containers for filling. |
| Before labeling, where required | Cooling or surface drying | Bring jars to a suitable condition for label application. |
| After capping or labeling | Date and batch coding | Add production dates, batch numbers or other information. |
| At suitable inspection points | Inspection equipment | Check selected packaging quality criteria. |
| After labeling and inspection | Carton packing and sealing | Prepare finished jars for storage and shipping. |
Optional equipment, conveyor connections and installation space should be confirmed separately in the project scope.
3. Six-Head Servo Piston Tracking Filling System
The filling system combines multiple filling heads, piston dosing, servo control and tracking nozzle movement. Each element serves a different role in the filling process.
Six-Head Configuration
Six filling heads support coordinated filling across multiple jars. Output depends on the quantity per jar, product flow and the operating speed of the connected equipment.
Piston Dosing
A controlled piston stroke measures product by volume. Pump, valve and nozzle selection must suit the product viscosity and any particles it contains.
Servo Control
Servo control regulates dosing movement. Operators adjust the filling quantity through the control panel and establish suitable settings during commissioning.
Tracking Filling Nozzles
The nozzles follow jars during dispensing. Nozzle travel and conveyor settings are coordinated with jar dimensions and the required filling cycle.
Filling Specifications
| Item | Specification |
|---|---|
| Number of filling heads | 6 |
| Standard filling range | 100–1,000 ml |
| Listed filling accuracy | ±1% |
| Other filling ranges | Subject to customization confirmation. |
Confirm the applicable specifications for the quoted configuration. Actual filling performance should be assessed under agreed product and operating conditions.
4. Steam Vacuum Capping for Glass Jars
The capping section is intended for compatible glass jars and metal twist-off lids. Closure performance depends on the packaging components and process settings.
How Steam Vacuum Capping Works
Steam displaces air in the jar headspace before the lid is secured. As the steam condenses during cooling, it helps create a vacuum. Filling temperature, headspace, steam conditions and seal integrity influence the final result.
Matching Jars and Lids
- Jar neck: Dimensions and finish matching the intended closure.
- Metal twist-off lid: Diameter, profile and sealing liner suitable for the process.
- Closure fit: Consistent engagement between the jar and lid.
Similar-looking lids can require different settings. Actual production samples are preferable when assessing closure fit.
Process Conditions and Closure Quality
Confirm the filling temperature, headspace and steam supply requirements during setup. Agree on lid application, seal integrity and vacuum acceptance criteria before production testing.
5. Product Suitability and Application Assessment
Jams, sauces and similar viscous products provide starting points for application assessment. Suitability should be evaluated using representative samples and the intended filling and closure conditions.
Key Factors to Evaluate
| Evaluation Factor | Details to Confirm |
|---|---|
| Product consistency | Smooth product or product containing fruit pieces, seeds, nuts or other particles. |
| Temperature and viscosity | Flow behavior at the intended filling temperature. |
| Product behavior | Any tendency to separate or change consistency during production. |
| Filling quantity | Required volume or net weight per jar. |
| Jar and lid specifications | Jar dimensions, neck finish and closure type. |
| Closure process | Compatibility with the intended steam vacuum capping conditions. |
Evaluating Peanut Butter
Smooth and chunky peanut butter may require different pump, product passage and nozzle configurations. Provide the intended filling temperature and, where applicable, nut particle size and content.
Test with the proposed jars, lids and target filling quantity before confirming suitability.
What Sample Testing Should Confirm
- Consistency of the dispensed quantity.
- Product flow and passage of particles, where applicable.
- Dripping or residue around the jar opening.
- Jar and lid compatibility and closure quality.
- Label placement and adhesion on the intended jar surface.
- Continuous operation across the connected equipment.
Agree on the test conditions, duration and acceptance criteria. Record acceptable output, rejected jars and stoppages so that results can guide the final configuration.
6. Evaluating Actual Line Capacity
The rated speed of an individual machine does not represent the sustained output of the complete line. Capacity should be assessed for the product, filling quantity and packaging format being used.
Understanding the Listed Speeds
Filling Unit
jars per hour · approximately
Listed filling speed, depending on filling volume and material.
Steam Vacuum Capping Unit
