These are the top 10 largest flour (wheat, durum, rye) milling companies in the United States according to Sosland Publishing Co.’s 2023 Grain & Milling Annual based on daily total capacity (cwts).

Besides being the newest flour mill in the United States, the Ardent Mills flour mill built along the Gulf coast in metropolitan Tampa, Florida, US, has several details that set it apart. Advanced analytics, state-of-the-art equipment, unusually large grain storage capacity and unique supply chain capabilities are among the mill’s distinguishing features.

At 17,500 cwts of daily flour milling capacity, the Port Redwing mill is not Ardent Mills’ largest and is not among the 25 largest flour mills in the United States. With the capacity to receive large quantities of wheat, though, Ardent Mills constructed a large grain elevator at the Port Redwing mill, with 4.1 million bushels of storage capacity.

The elevator may be the largest ever built concurrent with the construction of a US flour mill and, according to the 2022 Grain & Milling Annual published by Sosland Publishing Co., it is the sixth largest elevator of any US flour mill currently operating. The concrete elevator includes 12, 50-foot-concrete bins with 300,000 bushels of grain storage apiece as well as a number of smaller grain bins.

Alicorp SAA, Peru’s largest flour miller and a company with wide-ranging business interests, has expanded its flour production capabilities by nearly 50% at its plant in the Callao district near Lima, the nation’s capital.

The nine-floor, 1,700-square-meter plant now can produce 1,580 tonnes of flour (wheat equivalent) per day, an increase of 500 tonnes. The expansion, which was executed in existing space inside the building, includes a new milling line that features fully automated Bühler equipment.

The project included the installation of 35 Bühler roller mills, 3 plansifters, an automated bagging carousel and an optical grain sorter.

Other highlights of the project are the erection of wheat storage silos, the installation of concrete silos for wheat conditioning, and a truck filling station for flour and byproducts.

To qualify for the Grain & Milling Annual list, companies must have two or more facilities and total storage capacity of at least 6 million bushels. in 2022, there were 103 such companies. The Top 10 companies each exceeded 150 million bushels of storage.

Total corporate storage capacity includes country elevators and may not necessarily equal the sum of individual facility capacities listed in the directory. Total corporate capacity also may include storage at processing plants, which may or may not be listed in the directory.
