Triangle Package Machinery Co.

Triangle Package Machinery Co., Chicago, took elements from its existing X-Series vertical-form-fill-seal baggers and designed the new Compact Sanitary Bagger, Model CSB.

This smaller bagging machine can fit inside a narrow footprint and run bags up to 13 inches wide, while still offering durability, flexibility and superior sanitation.

Triangle modified components such as the control box, film cage and machine frame to fit into a narrow frame width of only 36 inches. To achieve maximum benefits, two compact baggers can be installed side by side (as a twin on 35-inch centers), sharing the same scale for filling the bags.

Model CSB runs speeds of 70-plus bags per minute, depending on bag length. When set up this way, two compact baggers can fit on one salad line, 35 inches on center, to produce 120-plus retail packages of leafy greens per minute. This also provides the flexibility to run varying film structures or film rolls, or to perform routine maintenance on one machine without disrupting production on the second machine.

To simplify cleaning and maintenance needs, the bagger is designed to be washed in place.

Additional sanitation benefits include:

  • Solid stainless-steel bar, fully welded and electropolished after welding;
  • Frame is solid round bar stock;
  • Internally mounted guard doors pivot on the frame, minimizing parts to improve sanitation;
  • Pivoting control box offers easy accessibility;
  • No slotted fasteners;
  • Sanitary, 3-A approved leveling feet;

Washdown-rated electronics, including IP67 washdown-rated motors for the pull belts, IP65 washdown-rated motor for the film unwind and a minimum IP67 rating for all other electrical components.

In addition, Triangle utilizes Rockwell controls, as well as optional RFID user management.

Finally, Model CSB also offers optional ultrasonic sealing, which is a cold sealing technology that seals right through product such as leafy greens, virtually eliminating package rejects and rework due to product in the seal.

Fortress Technology

Fortress Technology, Canada, unveiled how metal detection sensitivity is accomplished by multi-aperture multi-lane innovation, and showcased the latest Interceptor DF system, which delivers optimal food safety whilst helping to eradicate false product rejects.

Rather than channeling multiple lanes through a single metal detector, one Stealth metal detector is mounted across three conveyor lines. Each conveyor has its own BRC-approved reject system, and each aperture operates like a standalone metal detector. This puts a stop to an entire row of good product being rejected and wasted if a contaminated product is identified on one line.

Each aperture is sized as closely as possible to the product. As a result, the system is more sensitive to smaller metal particles and copes better with orientation and product effect.

Fortress also collaborated with Sparc Systems, UK, to design a 5-aperture metal detector combined with a 5-lane checkweigher, helping to reduce product giveaway through over or under filling of pre-packed foods. The system also features contact data software for enhanced traceability, and a mobile app for remote examination to avoid repeat production stoppages.

Meanwhile, the Interceptor DF returned. Inspecting low-profile, high-value foods vertically and horizontally at the same time, the Interceptor DF increases the probability of identifying and rejecting products containing non-spherical metals by over 100%, including difficult-to-spot flat metal flakes.

GEA North America

GEA North America, Northvale, N.J., optimized its TwinTube packaging machine to promote flexibility and automation

The redesigned high-speed vertical packaging machine GEA SmartPacker TwinTube now boasts a future-proof modular system with increased functional efficiency promoting higher operational uptime and ease of use.

The TwinTube is a continuous motion vertical machine, suitable for packaging small-sized food products and on-the-go products in pillow bags of different sizes. It operates with two parallel forming tubes, achieving combined speeds of up to 500 bags per minute (weighing 10-18 grams each). It also runs a different film reel for each tube, meaning calorie packs of different widths or designs can be simultaneously filled.

A new feature to the machine is the Jumbo Roll, which allows film reels of up to 100 kg to be used for long production runs.

The new SmartPacker TwinTube is also equipped with automated web tracking. This means that if the film deviates from its path, due to variances in the film roll, the feature will correct the direction of the film automatically, without the need of manual adjustment.

The new SmartPacker also features a new jaw closing mechanism, optimized heating unit and a vertical rotational seal unit, promoting tightness of the pack seals. The jaw closing mechanism offers more than triple sealing force as the previous one and can apply 6000N. This gives the opportunity to use thicker films or films with more diverse characteristics in terms of sealing requirements.

The new GEA TwinTube is optionally equipped with a new, fully integrated GEA TiroLabel unit, which makes the machine even more compact on the factory floor. The dedicated labeling unit delivers a speed of up to 180 labels per minute at a width of 150 mm and achieves millimeter precision during labeling. The label roll has a quick-release operation, which means it can be changed in seconds with minimal downtime.
