A look inside HP Hood's Sacramento plant
HP Hood fills 600 bottles a minute on its new aseptic line in its Sacramento, Calif., plant. The company processes dairy and nondairy beverages in aseptic and extended shelf life packages.
The plant’s on-site quality assurance lab is approved by the FDA and the state of California. The lab tests a 2-ounce vial of milk from every tanker. The lab conducts all raw milk testing (except for payment samples), fats and solids tests, composition test, 48-hour hold-and-release testing and end-of-code testing.
The lab also tests ESL start-up samples pulled by filler operators. Line samples are taken by the lab hourly and held for 48 hours in a storage room in the lab. Elsewhere in the plant, samples from every run (including branded and co-packed products) are retained and held in a cold room for seven days past code date.
Aseptic quality protocols are more extensive, and a governmental agency approves the release of product for sale, Hardy said. Two QA technicians work in the aseptic packaging room and are responsible for sampling and testing. Aseptic samples are held for 10 days at 86 degrees before being released. The California Department of Public Health conducts a final document review and approves the product for sale.
HP Hood chairman Kaneb called the decision to buy an aseptic filler for Sacramento a “$40 million bet” for each filler and associated infrastructure. He said, “If you don’t have extremely well-trained people running your system, you are courting big trouble legally and financially.”
Aseptically packaged beverages in portable containers are “useful for the civilization we live in,” he said. And while consumers are on the go seemingly 24/7, they’ll never reach the speed of the rotary aseptic filler.
