How Precisely Can a Burger Patty Packaging Line Stack Multiple Patty Sizes?

A modern burger patty packaging line combines optical detection, servo-driven positioning, adjustable interleaving, and stored production recipes to create uniform stacks from different patty formats. It can process round, square, and oval patties measuring 80–180 mm in diameter and 5–30 mm in thickness. Operators can set pack quantities from 2 to 20 patties, while tool-free adjustments allow changes to product size, stack height, and film width in less than 10 minutes.

Packaging Capability at a Glance

• Optical sensors track incoming patties, while servo-controlled pushers count and position each piece accurately within the stack.
• The equipment accommodates round, square, and oval products ranging from 80 mm to 180 mm in diameter and 5 mm to 30 mm in thickness.
• Pack configurations can be programmed for 2–20 patties, including commonly used formats such as 2, 4, 6, 8, 10, and 12 pieces.
• The system is suitable for frozen food factories, meat processors, plant-based protein producers, QSR suppliers, and convenience-food manufacturers.

How the Stacking Process Works

Product Infeed and Alignment

Patties enter the line from a forming machine, freezing tunnel, or upstream conveyor. An automatic infeed conveyor maintains continuous product delivery, while vibration-based alignment organizes the patties into a controlled single-file flow. Depending on patty dimensions, product characteristics, and operating conditions, the line can handle throughput of up to 150 patties per minute.

Interleaving Between Patties

When individual patties must remain separated during freezing, transport, or storage, the interleaving module inserts food-grade wax paper, PE film, or release liner between product layers. Adjustable tension and cut-length controls help provide consistent separation while reducing unnecessary liner consumption.

Counting and Stack Formation

At the stacking section, optical sensors monitor the product stream and confirm the arrival of each patty. Servo-controlled pushers then transfer the patties into predetermined stacks, helping maintain consistent layer positioning across different sizes and shapes. Operators can modify stack height, product dimensions, and other format parameters without using tools. The available product information confirms repeatable alignment but does not specify a numerical stacking-tolerance value.

Wrapping, Inspection, and Control

Once a stack has been formed, the horizontal flow wrapper packages it in a pillow-style pack with either a fin seal or lap seal. Compatible packaging materials may include heat-sealable OPP, PET, and compostable films. Depending on the production requirement, the line can also be configured for gusseted bags, vacuum-skin packs, modified-atmosphere packaging with nitrogen or carbon dioxide flushing, or tray sealing with lidding film.

A PLC and 10-inch HMI touchscreen manage the operating sequence and can store up to 100 product recipes. The interface provides production monitoring, OEE information, and fault diagnostics to support rapid format changes. Optional equipment includes date and batch printers, metal detection, checkweighing, and automatic rejection. Nonconforming packs can be removed from the product flow without stopping the entire line.

The machine is built with an AISI 304 stainless steel frame and an IP65 washdown rating. Accessible panels support routine cleaning and maintenance. The supplied product information identifies CE, UL, and HACCP compliance, while the enterprise certification record lists a CE certificate covering flow packaging machines, automatic packaging systems, cartoning machines, and palletizing robots.
