Tri-Pak Machinery, Inc. Custom design, engineering and manufacturing of packing house machinery systems for fresh fruits and produce. Tri-Pak Machinery, Inc.

designs and builds high quality, custom packing house equipment for the fresh produce industry, as well as an extensive line of industrial ice crushers, and some of the best shrimp grading machinery available. Beginning in a one-car garage in 1934, our founder J.R. Fitzgerald formed this small family organization after years of working in fruit and vegetable packing sheds across Texas, alongside h

is wife, Vestal. It was a struggling business venture for J.R. (better known in the industry as “Bob”), but he knew that he had a product that the produce industry definitely needed. Tri-Pak soon expanded to its current 4.75-acre location in 1939 as it helped pioneer the mechanization of the produce industry. He envisioned a more efficient system of sorting and packing the produce with his first invention, a sorting conveyor for tomatoes. Where tomatoes were previously being individually wrapped in tissue paper to prevent damage during transit, he discovered that they could be lubricated with a thin film of food-grade wax for the same effect with less packaging waste. He also found that the same number of workers could increase their throughput by dumping the product onto a moving conveyor for a line of workers to sort into finished boxes rather than each worker sorting from box to box directly. Utilizing a conveyor system also allowed for additional modular machinery, leading to the development of an all-inclusive packing line that served to wash, dry, wax, sort by size, grade by ripeness, and pack into a finished product ready to ship to the local grocers. Tri-Pak’s reputation for excellence is built on Bob’s philosophy that the pillars of quality, quantity and uniformity are integral to creating a lasting product and a satisfied customer. These 3 principles were the inspiration for the triangular logo and company namesake. Over the years, more buildings have been added while the Tri-Pak facility has expanded to include the design and manufacture of equipment for packing onions, carrots, potatoes, cucumbers, citrus fruit, cabbage, shrimp and other items. The most modern technology has continued to be incorporated in the manufacturing process and the firm's reputation for quality, dependability and service has grown worldwide. Our machines can be found in operation in Great Britain, Germany, Australia, New Zealand, Canada, Mexico, Saudi Arabia, several countries in Central and South America, Africa, and in the Caribbean Islands as well as all across the United States. Tri-Pak is presently being managed by the third and fourth generations of Fitzgeralds: David, Jim and his son Austin, as well as a few long-time employees who have basically become part of the family. The company continues to look ahead to better and more efficient machinery, utilizing the newest technology and ideas available, keeping with the tradition of quality, quantity and uniformity originally started in that small garage more than 80 years ago.

This Day in History: The “Accidental” Invention That Changed Manufacturing

On August 13, 1913, metallurgist Harry Brearley was trying to solve a problem inside gun barrels: steel that could withstand extreme wear. His experiments led to an unexpected discovery. By adding chromium, he created a steel that resisted corrosion far better than conventional steel.

What began as an attempt to make better gun barrels soon found an entirely different application. The new “rustless steel” became especially valuable for cutlery and food handling, eventually evolving into the stainless steel we rely on throughout modern food processing.

More than a century later, stainless steel remains a workhorse of the produce industry. At Tri-Pak, it’s used throughout our machinery wherever durability, corrosion resistance, and cleanability matter.

Brearley’s story offers a useful lesson for engineers and manufacturers: sometimes the best solution is hiding in the result you weren’t looking for. Good engineering isn’t always just about solving the problem in front of you. It’s about recognizing what your experiments teach you along the way.

Yesterday, Jim Fitzgerald, President/Owner of Tri-Pak Machinery, Inc., and Sam Gonzales, Office Manager, had the pleasure of meeting with City Commissioner Daniel Lopez.

We had a productive and informative discussion about Tri-Pak's history, our manufacturing capabilities, and the role we hope to continue playing in the growth and success of the City of Harlingen.

We appreciate Commissioner Lopez taking the time to visit with us, and we look forward to strengthening our relationship with the City and exploring future opportunities to support our community.

Winter festivals are coming... even if the forecast misses the memo.

If Mother Nature decides to sit this holiday season out, the Tri-Pak G-40 Mobile Ice Slinger is ready to take her place. Just add ice, and turn any celebration into a winter wonderland.

Love seeing Vicencio's Ice spreading holiday magic across El Paso!

El Paso, Texas-- With the holiday’s quickly approaching, Vicencio's Ice Distributors is bringing back a tradition they put on hold for the past 15 years. Snow parties! “I mean this is like a real life fantasy really this is like a daydream or maybe even a dream itself,” said 10-year-old Alessa...

STEM skills are becoming essential in almost every career, and they'll be even more important for the next generation.

It's exciting to see our local library introducing kids to 3D printing—one of the same technologies that's changing the way products are designed and manufactured around the world.

Today's classroom project could be tomorrow's engineering breakthrough. If you have a young maker at home, be sure to sign them up!

Post-Harvest Processing Equipment for Fresh Produce Growers & Packers

07/08/2026

Most people don't think of ice as a concrete ingredient—but on hot summer pours, it can make a big difference.

Concrete doesn't simply "dry" as it hardens. It goes through a chemical curing process that generates heat, and high temperatures can speed that process up more than crews want. Adding crushed ice helps keep the mix cooler and gives crews more workable time.

This short video does a great job explaining the science behind it.

If you didn't know industrial ice crushers are used for concrete production, you're not alone. It's just one of the many industries we serve. Learn more about our ice crushing equipment at www.tri-pak.com/ice/
