Hamburger Patty Stacker, Counter & Interleaver Machines

Interleaving Hamburger Patties

With a variety of configurations coming from your patty former, you need a flexible solution to match patty sizes and your lane layouts. The Pacproinc® PPI-200 line of interleavers accurately and consistently places a pre-programmed sheet of paper, film, or foil under or around your product at speeds up to 600 pieces per minute. The PPI-200 hamburger patty stacker, counter and interleaver machinery is ideal for interleaving scored patties, whether you select the single-lane configuration, purchase the alignment device for multi-lane setups, or choose a complete single-lane system for interleaving/stacking/tray loading.

The paper, film, or foil sheet can be folded or wrapped around the product for ease of separation, sanitary handling, freeze release, improved shelf life, and portion control.

Interleaved (underleaved) products can be conveyed to one of our modular auto stackers for hands-free counting and auto stacking before introduction to your packaging or wrapping machine.

Gain additional line flexibility with our bypass option. This option is available to accommodate processing of non-interleaved or non-stacked product and allows these products to be introduced to the packaging machine without having to take the interleaver or stacker out of the line.

Interleave Fresh Formed Burgers

Pacproinc®‘s 19″ wide interleaver introduces paper under hamburger patties in multiple lanes for the purpose of freeze release.

Patties & Burgers Alignment

Pacproinc® hamburger patty stacker, counter and interleaver machines correct leading-edge misalignment in multi-lane operations by straightening fresh or frozen food products into neat, even rows for consistent interleaving.

All of our solutions are available as a combination interleaver and stacker or as standalone components designed to fit your application. The PPI-200 product line is a sanitary, washdown-duty, stainless steel system. The streamlined design incorporates leading-edge Programmable Logic Controller (PLC) and servo motor technology, ensuring low maintenance and a long machine life. With compact designs available, the PPI-200 hamburger patty stacker, counter and interleaver equipment requires a minimal amount of floor space and is engineered to exceed the American Meat Industry’s 10 Principles of Sanitary Design.

The PPI-200 product line features rugged, stainless steel construction and climate-controlled (dehumidified), fully gasketed enclosures. Our PLC-based design enables easy production setup and changes, as well as networking with other equipment.

Our equipment designs and superior construction go beyond simply addressing the need for efficient operation—ease of sanitary maintenance is central to our solutions:

  • Stand-off mounted components prevent the trapping of any product scrap improving sanitation
  • Ground and polished welds further eliminate bacteria harborage points, making cleaning to a microbiological level possible
  • All control cabinets and enclosures have sheet metal breaks eliminating the possibility of standing water on flat surfaces
  • We use sealed stainless steel bearings in all food-contact areas to prevent product contamination and offer optional, antibacterial belting
  • All machines are available with casters or leveling pads to meet your plant’s unique requirements
  • Trays keep product scraps out of the paper path and paper tails off the floor to prevent material contamination
  • Welded construction eliminates recessed bolt heads and other areas that could collect product cast-offs and harbor bacteria growth

Pacproinc® equipment is built to accommodate your application, with standard operating widths ranging from 3-40”. These solutions can be configured for single lane, multiple lanes, or unique groupings.

Our patented jam detectors significantly reduce costly downtime, and the PPI-200 includes Allen Bradley controls and touch screens as standard equipment. All programming is done by our in-house automation engineers, and all Pacproinc® systems are supported by our 24/7 service team.

Stand-Alone Counter/Stackers

Don’t need interleaving? No problem. Pacproinc® offers a variety of modular counter/stackers to fit any application, and our custom designs easily interface with upstream production equipment and end-of-line packaging machinery.

High-speed, sanitary, hands-free counting/auto stacking guarantees better, more accurate stacks for easier packaging and improved product presentation.

Counting and auto stacking reduces labor and training expenses, as well as the incidence of repetitive motion injuries. The PPI-200 increases line throughput while cutting operating costs and improving your product presentation and packaging.

Like all of our designs, our stand-alone counters/stackers feature rugged, stainless steel construction and climate-controlled, fully gasketed enclosures. Our PLC design enables easy production setup and changes to parameters like stack count, delay, speed, and portion thickness, and our solutions are easily networked with other equipment to seamlessly interface with production requirements like product changeover or stoppages.

Pacproinc®’s layer pack line will accept product from any slicer or former, group the product flow, interleave with a single sheet of paper or film, and create a final stack that can be fed to a wrapping machine or other packaging equipment to eliminate multi-station layer packing.

The PPI-200 VERSA-STAX stacker can also interleave, stack, and tray load at speeds up to 300 portions per minute. Designed specifically for single-lane, homestyle patty formers, it can be used in conjunction with an automatic tray de-nester or as a standalone stacker, and product can be stacked with or without paper.

Adding a PPI-200 Interleaver to your line will provide the automatic placement of paper under each portion, and the VERSA-STAX features programmable stack counts and tray loading configurations, as well as a loading feature for various tray sizes.

Sausage Patty Auto Stacker

This Pacproinc® solution automates the counting and stacking of formed or sliced burgers. Coupled with a Grouper and/or an Interleaver this solution is capable of automatically generating a finished layer pack.


Whether you are interleaving and stacking or just stacking, many of Pacproinc®’s auto stacking modules have the ability to load your counted and stacked product directly into the package. We have extensive and unique experience handling stacked food products, which allows us to introduce finished stacks directly into trays, cartons, or pockets.

ProLeaver Burger Paper Interleave and Stack

Interleave, Count, Stack, and Tray Load burger patties at speeds up to 100 burgers per minute.

Tray Loading

When used in conjunction with an automatic tray denester and tray-loading module, it eliminates the need to manually interleave and package case-ready patties.
