Rotary filler technology
Industrial canning machine – Luthi Tuna Filler (LTF)
Rotary precision for chunk-style products and beyond
Luthi Tuna Fillers (LTF) – Rotary Fillers are designed for accurate fill weight, maximum product yield, attractive food appearance and high production speed.
Chunk-style tuna, meat and pet food applications
Chunk-style tuna, meat and pet food applications
This industrial canning machine platform serves diverse sectors across the global food processing industry. From seafood canneries processing albacore and skipjack tuna to poultry processors packing premium chicken breast, the rotary filler design maintains product integrity while maximizing throughput.
There are a series of models available for specific applications to ensure that the accuracy, speed, production rate and end product integrity are maintained.
Model LTF – this rotary filler machine is designed for chunk-style products where ingredients must maintain distinct pieces. The LTF model excels at tuna chunks, tuna salad blends, and certain pet food formulations.
Model MPF – this filler is purpose-built for meat, poultry and pet food products requiring superior visual appeal. When processing, this filler ensures your product looks as good as it tastes.
Key features
Overfilling is minimized
Overfilling has a direct impact on your bottom line. Luthi fillers are the most accurate in the industry, and, in most cases, weight can be maintained within ±2% of target.
Maximum product yield
Uniform density is key to maximizing your product yield – and likewise your profits. Precise adjustment to air pressure control enables you to customize the filling density to the type of product you are packing or other process parameters.
Food appearance is enhanced
Appearance is a key factor in consumer preference. To ensure an attractive presentation, Luthi rotary fillers form your product into the required size and shape before transferring it to the container.
Luthi fillers are fast
Luthi rotary fillers are designed to fill 90 to 600 cans per minute. Faster filling means you are able to maximize plant capacity with fewer machines or install more machines and produce more salable product. Either way, your bottom line benefits.
Container flexibility
When you order a Luthi rotary filler, it is built to your container and fill weight requirements. Consequently, when your market or products change, you can easily change too. Machine parts to accommodate other container sizes are just a phone call away.
Reliability
Our fillers are built to operate 24 hours a day, seven days a week, with minimal downtime. Severe operating and environmental conditions, including very high temperatures and humidity, are not a problem. Fully mechanical in construction, our fillers contain few electronic components.
Sanitation
Luthi fillers are constructed of food-grade-approved materials.
