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 recipe control 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. Pack configurations can be set from 2 to 20 patties, while tool-free adjustments allow operators to change product dimensions, stack height, and film width in less than 10 minutes.

Packaging Capabilities at a Glance

• Optical sensors track patty flow and servo pushers place each product accurately into the programmed stack position.
• The equipment accommodates round, square, and oval patties within the specified 80–180 mm diameter and 5–30 mm thickness range.
• Stack counts are programmable from 2 to 20 pieces per package, including common formats such as 2, 4, 6, 8, 10, and 12 patties.
• The system is suitable for frozen-food factories, meat processors, plant-based patty producers, QSR suppliers, and convenience-food packaging operations.

How the Stacking System Works

Product Infeed and Alignment

Patties enter the line from a forming machine, freezing tunnel, or upstream conveyor. An automatic infeed conveyor transfers the products toward the stacking section, while vibration-based alignment organizes them into a controlled single-file stream. Depending on patty characteristics and operating conditions, the line can handle product throughput of up to 150 patties per minute.

Interleaving and Separation

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

Counting and Stack Formation

Optical sensors monitor the passing products and send counting information to the control system. Servo-controlled pushers then transfer the patties into the required stack arrangement. Operators can adjust the product format, stack height, and related settings without tools, helping the line maintain repeatable layer placement when switching between sizes.

The available product information confirms consistent alignment control, but it does not specify a numerical stacking-tolerance value. Actual alignment performance may therefore depend on patty shape, thickness variation, surface condition, and the final machine configuration.

Wrapping, Inspection, and Control

Once a stack is completed, a horizontal flow wrapper seals it into a pillow-style pack. The machine can use heat-sealable materials such as OPP, PET, or compostable film and may be configured with either fin seals or lap seals. Depending on the packaging requirement, other formats can include gusseted bags, vacuum-skin packs, modified-atmosphere packaging with nitrogen or carbon dioxide flushing, and tray sealing with lidding film.

A PLC and 10-inch HMI touchscreen provide recipe management, operating-status monitoring, fault diagnostics, and real-time OEE information. Up to 100 product recipes can be stored for faster repeat production. Optional equipment includes date and batch printers, metal detection, checkweighing, and automatic rejection. Nonconforming packs can be diverted from the production flow without stopping the entire line.

Construction and Sanitation Features

The line is built with an AISI 304 stainless steel frame and is described with an IP65 washdown rating. Accessible panels support routine cleaning and maintenance in food-processing environments. The stated compliance information includes CE, UL, and HACCP requirements. The enterprise certification record lists a CE certificate covering flow packaging machines, automatic packaging systems, cartoning machines, and palletizing robots.
