Eliminate Bottlenecks Before and After Retort Sterilization
Manual retort crate loading creates severe bottlenecks in canning facilities. Thermal hazards, container denting, and worker fatigue continuously slow down production. Automating basket handling protects container integrity and keeps continuous retort cycles strictly on schedule. Manual handling slows the entire line.
The LWT automated basket loading and unloading system handles full layers of containers smoothly. It connects directly with your upstream can depalletizer and downstream retort sterilizer machine. Canning plants across Europe, Latin America and Asia rely on LWT systems. This includes proven operations on Turkish and Russian canning lines.
Dual-Mode Handling for Cans, Jars, and Bottles
Different food and beverage packages require dedicated layer gripping technology. Our systems offer tailored transfer heads designed for specific container materials:
- Magnetic Layer Transfer: Electromagnetic tooling lifts full layers of tinplate cans gently without scratching lithography or denting flanges.
- Pneumatic Clamping Head: Multi-segment pneumatic side grippers hold glass jars, glass bottles, and aluminum containers securely across every cycle.
- Automatic Interlayer Management: Integrated vacuum suction cups place and collect plastic or stainless divider pads automatically between container tiers.
Dual handling modes prevent container denting, glass chipping, and surface scratches at high speeds. Each layer moves smoothly right after seam inspection by an automatic can seamer. The handling stays gentle.

Typical Application Examples |
Key Operational Benefits & Value |
| Tinplate / Metal Cans |
Electromagnetic Layer Suction |
Luncheon meat, tomato paste, tuna/sardines, sweet corn, mixed congee, canned mushrooms |
Powerful magnetic transfer protects surface lithography and coatings, preventing flange deformation and can body scratches. |
| Glass Bottles & Wide-Mouth Jars |
Pneumatic / Air Cushion Clamping |
Chili sauces, jams, pickled vegetables/cucumbers, bird's nest, fish maw, condiment sauces |
Flexible pneumatic cushions provide uniform peripheral gripping, completely eliminating glass chipping, micro-cracks, and breakage. |
| Aluminum Cans (2-Piece & 3-Piece) |
Multi-Segment Clamping / Vacuum Suction |
Plant protein beverages, milk drinks, RTD coffee, tea drinks, beer, functional beverages |
Evenly distributed side-clamping pressure prevents thin-walled aluminum cans from denting or collapsing under load. |
| High-Barrier Retort Bowls / Cups / Trays |
Custom Vacuum Cups / Tray Grippers |
Ready-to-eat meal bowls, self-heating rice, sterilized puddings/jellies, stewed soup packs |
Gentle vacuum tooling handles custom-shaped, heat-resistant plastic containers with stable multi-tier layer indexing. |
Key Operational Benefits of LWT Basket Handling Systems
Transitioning to automated basket management delivers quantifiable labor savings. Facilities eliminate physical strain while establishing consistent sterilization schedules.
Synchronized layer indexing cuts retort turnaround times while reducing factory floor labor. After autoclaving, unloaded containers discharge steadily into an automated can labeling machine. The workflow runs uninterrupted.

Comprehensive Production Line Integration
Every handling system integrates seamlessly with upstream filling lines and downstream packaging equipment. LWT engineers design custom conveyor layouts, automated basket shuttles, and buffer tables. Downstream cases feed directly into a high-speed carton packaging machine. Turnkey execution saves setup time.
Frequently Asked Questions
Q1: How does the system adapt to different can and jar heights?
The Siemens PLC stores multiple product recipes with automated vertical stroke positioning. Quick-clamp changeover parts allow your team to switch container sizes within minutes without specialized tools.
Q2: What factory inspection and testing services does LWT provide before dispatch?
Founded in 2009 in Shanghai, LWT operates with 25 dedicated R&D engineers and 14 technical patents. We conduct factory acceptance tests with your sample cans, providing full video verification and on-site inspection before dispatch.
Q3: Can a single system handle both magnetic tin cans and fragile glass containers?
Yes. We configure interchangeable magnetic suction plates and pneumatic clamping heads on the same gantry frame. Operators can swap gripper assemblies rapidly when switching container types.
Q4: What warranty and after-sales technical support are included?
All LWT equipment includes a standard 1-year warranty covering mechanical and electrical components. Our engineers provide lifetime remote technical assistance, overseas on-site commissioning, and rapid spare parts supply.
