The History of AZO Inc.

feature image

AZO Inc. is celebrating more than four decades in the industry. But we want you to know where it all began. Our company’s rich and storied history is built on the values we exude today.

The word “innovation” may not immediately bring to mind a flour miller and the son of a preacher, but these descriptions fit the two people responsible for starting an exceptional American service, sales and support organization that has lasted 40 years.

Hunt Moore formed a relationship with Adolf Zimmerman, the founder and owner of AZO, by traveling and seeking key German business owners and asking to be their manufacturer’s representative in the United States. At the time, this was an extremely forward-thinking move for a business man in the Bluff City (Tennessee).


Adolf Zimmerman and Hunt Moore shake hands in 1978. For 40 years AZO Inc. has provided exceptional service, sales and support in America as AZO GmbH provides quality German engineering.

After representing Zimmerman for 15 years and cultivating a friendship between the two families, Moore was asked to help start the American subsidiary of Zimmerman’s company. The rest is history.


AZO Inc. is founded in Memphis, Tenn., as a partnership between the Moore and Zimmerman families. The business was set up as a corporation but managed as a partnership.

This food mix facility originally made 10 products, but now produces 120 products thanks to original innovation by AZO Inc.

As then-president Bob Moore noted that "no one spent as much time" in the existing facility as former employee Thorp Callaway, the one-million-dollar facility was renamed the "Thorp Callaway Ingredient Automation Test Facility."

"Up until his retirement in 1993, Thorp Callaway was, without a doubt, a champion for AZO equipment in North America," Moore said at the event. "It's an honor to recognize Thorp since his hard work, in large part, made this facility possible." 

Since then, AZO Inc. has had the ability to capably test ingredients, take samples and evaluate whether the material will be easy to handle in a pneumatic conveying system. Clients are welcome in the testing center to view tests in person, or videos can be sent demonstrating how they're conducted.

AZO Inc. is awarded among the Memphis Top Workplaces by The Commercial Appeal. This annual list is based on employee surveys from hundreds of different companies and organizations. Fifty five are awarded in the end. AZO was also awarded in 2014, 2016, 2017 and 2018.


AZO Inc. begins design and construction of its largest dry mix plant for a global food manufacturer. The first North American ShuttleDos Componenter was planned for this facility.


Special advantages of the CleanDock® include an easy to clean design, reliable contamination prevention and automatic docking of containers, big bags and drums.


The top of the line Componenter, the ShuttleDos, is placed in operation at a global food manufacturer in the U.S. This Componenter contains the “CleanDock ®” feature on top of each shuttle, which prevents dust from entering the process between the container and dosing device. It also separates ingredients from allergens and non-allergens, ensuring cross contamination between the dosing points does not take place.


The Engineer In Training program is formally created and staffed. The three-year program introduces recent college graduates to AZO technology in system design, project management and customer service.


Thanks to a booming economy and the addition of upgraded resources, AZO Inc. reports $42 million orders in a single year. This record was due partly to marketing efforts, sales efforts and project management efforts that allowed the company to take on more business.

In 2018, AZO Inc. was also awarded as the “Corporate Volunteer Partner of the Year” by Memphis Public Libraries, and, in addition to placing in The Commercial Appeal’s Top Workplaces, was presented a special award in recognition of “Work/Life Flexibility.”


AZO Inc. in 2019


Celebrating AZO Inc.’s 40th anniversary, the company renovated its offices to continue the tradition of exceptional service, sales and support in America. AZO provides high-quality German engineering and American customer service — offering the best of both worlds just as the company has for 40 years.


In 1952, 26 years before the American subsidiary of AZO was formed, Adolf Zimmerman launched the first cyclone screener onto the German market. To this day AZO Inc. still sells robust and heavy duty screeners in America that are based on the founding ideas that made Zimmerman’s first machine such a success.
