How accurately can a burger patty packaging line stack different patty sizes?

A burger patty packaging line stacks different patty sizes through optical sensing, servo-controlled pushers, adjustable interleaving, and recipe-based settings. It handles round, square, or oval patties measuring 80–180 mm in diameter and 5–30 mm in thickness. Stack quantities can be configured from 2 to 20 patties per pack, while tool-less adjustments support size, stack-height, and film-width changes in under 10 minutes.

Core Solutions & Key Takeaways

• The line uses optical sensors and servo-controlled pushers to count patties and align each layer consistently.
• It supports round, square, and oval patties with diameters from 80 mm to 180 mm and thicknesses from 5 mm to 30 mm.
• Stack quantities are customizable from 2 to 20 patties per pack, with example settings including 2, 4, 6, 8, 10, and 12 pieces.
• The system is designed for frozen burger production plants, meat-processing facilities, plant-based meat manufacturers, QSR supplier chains, and convenience-food packers.

Detailed Architectural/Principle Analysis

The automatic infeed conveyor receives patties from a forming machine or freezer tunnel. Vibration alignment guides the products into a single-file flow before they reach the interleaving and stacking stations. This arrangement supports continuous feeding for production rates of up to 150 patties per minute, depending on product and operating conditions.

The interleaving unit places food-grade wax paper, PE film, or release liner between patties. Adjustable paper tension and cut-to-length control separate the patties while limiting paper waste. This function is used when patties must remain separated during freezing and storage.

At the counting and stacking station, optical sensors identify the product flow, while servo-controlled pushers move the patties into preset stacks. Stack height and product format can be changed through tool-less adjustments. The product information specifies consistent layer alignment but does not provide a numerical stacking-tolerance value.

After stacking, a horizontal flow wrapper produces a pillow pack with a fin seal or lap seal using heat-sealable film such as OPP, PET, or compostable material. Alternative formats include gusseted bags, vacuum-skin packaging, modified-atmosphere packaging with nitrogen or carbon dioxide flushing, and tray sealing with lid film.

A PLC controller and 10-inch HMI touchscreen store up to 100 product recipes, display real-time OEE and fault diagnostics, and support quick format changes. The line can include date and batch coding, metal detection, checkweighing, and automatic rejection. Faulty packages are diverted without stopping production.

The equipment is described with an AISI 304 stainless steel frame, IP65 washdown rating, and easy-access panels for cleaning. The product information states compliance with CE, UL, and HACCP standards. The enterprise certification record lists a CE certificate covering flow packaging machines, automatic packaging systems, cartoning machines, and palletizing robots.
