McKee Foods, the US snacks group, is expanding its production capacity at its plant in Tennessee.
The company did not specify by how much production would increase at the site in Collegedale, with a spokesperson insisting the information was "a competitive advantage".
The spokesperson added: "We do not publicly discuss what products are made where because it can speak to our capacity."
In total, around US$102.5m is being spent on the site. McKee plans to invest $78.5m on production, with the remainder on expanding its corporate office in Collegedale.
"When we began seeing near-exponential growth beginning in the 1980s, our tack of building to meet needs transformed into one of building to exceed needs and to somewhat future-proof our capabilities to meet rises in demand. This expansion supports our business goals and makes us more nimble, increases efficiency and reduces waste," the spokesperson said.
McKee, which generates annual sales of $1.4bn, owns brands including Little Debbie snack cakes and Sunbelt granola snacks.
