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

A modern burger patty packaging line can handle different patty formats by combining optical detection, servo-driven positioning, adjustable interleaving, and recipe-based controls. Depending on the configuration, the system can process round, square, and oval patties measuring 80–180 mm in diameter and 5–30 mm in thickness. Operators can set the required pack quantity from 2 to 20 patties, while tool-free adjustments allow changes to product size, stack height, and film width in less than 10 minutes.

Performance Overview

The line is designed to maintain consistent product flow and layer alignment across a wide range of burger patty sizes. Optical sensors track each patty, and servo-controlled pushers move the products into accurately defined stacks. Although the available specifications do not state a numerical stacking tolerance, the control system is designed to provide repeatable positioning throughout continuous production.

• Processes round, square, and oval patties with diameters from 80 mm to 180 mm.
• Handles patty thicknesses ranging from 5 mm to 30 mm.
• Supports configurable stacks of 2 to 20 patties per package.
• Uses optical sensing and servo motion control to improve counting and alignment.
• Provides recipe-driven settings and tool-less format changes in under 10 minutes.

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 alignment helps arrange them into a stable single-file stream. Under suitable operating conditions, the line can process up to 150 patties per minute, although the actual rate depends on patty dimensions, product condition, and selected stack quantity.

Interleaving Between Patties

When individual patties must remain separated during freezing, storage, or distribution, the interleaving unit inserts food-grade wax paper, PE film, or release liner between layers. Adjustable paper tension and cut-length controls help match the separator material to the patty format while reducing unnecessary waste.

Counting and Layer Formation

At the stacking station, optical sensors monitor the product stream and identify each incoming patty. Servo-controlled pushers then guide the patties into the programmed stack arrangement. Operators can adjust the product format, number of layers, and stack height without using tools, allowing the same line to support several package specifications.

Packaging and Quality-Control Options

Once the stack is complete, a horizontal flow wrapper forms the package using heat-sealable materials such as OPP, PET, or compostable film. The standard format is a pillow pack with either a fin seal or lap seal. Depending on the production requirement, the equipment can also be configured for gusseted bags, vacuum-skin packs, modified-atmosphere packaging with nitrogen or carbon dioxide flushing, and tray sealing with lidding film.

A PLC-based control system and 10-inch HMI touchscreen allow operators to store up to 100 product recipes. The interface can display real-time OEE information, alarm messages, and fault diagnostics. Optional equipment includes date and batch coding, metal detection, checkweighing, and automatic product rejection. Packages that fail inspection can be diverted from the main flow without requiring a full production stop.

Construction and Operating Environment

The equipment is described as having an AISI 304 stainless steel frame, an IP65 washdown rating, and accessible panels that simplify cleaning and maintenance. The supplied product information references CE, UL, and HACCP compliance. The company certification record also lists CE coverage for flow packaging machines, automatic packaging systems, cartoning equipment, and palletizing robots.

Frequently Asked Questions

How does the machine align different patty sizes?

The system first uses vibration alignment to establish a controlled single-file flow. Optical sensors then track product movement, while servo-driven pushers place each patty into the programmed stack position. Adjustable recipes allow operators to match the settings to the patty dimensions and packaging format.

Can operators change the number of patties in each pack?

Yes. The specified operating range is 2 to 20 patties per package. Common configurations may include 2, 4, 6, 8, 10, or 12 patties, with the final setting selected according to the required retail or foodservice pack format.

Is an exact stacking tolerance provided?

No numerical tolerance value is included in the available product data. The stated design uses optical monitoring, servo positioning, and adjustable stack controls to achieve consistent layer alignment, but exact tolerance should be confirmed for the specific patty recipe and package configuration.

Which businesses can use this type of line?

The equipment is suitable for frozen burger factories, meat-processing plants, plant-based meat producers, QSR supplier networks, and convenience-food packaging operations that need repeatable counting, interleaving, stacking, and wrapping.

Conclusion

A burger patty packaging line can stack multiple patty sizes reliably by coordinating product alignment, optical counting, servo positioning, and recipe-based adjustments. Its stated product range, configurable stack quantities, interleaving capability, inspection options, and fast tool-less changeover make it suitable for flexible high-volume production. Because the published information does not specify a numerical stacking tolerance, buyers should request product trials or a detailed technical specification for their exact patty dimensions and packaging requirements.
