Technology for the poultry industry

Georgia's nation leading poultry industry has been the catalyst and chief beneficiary of the application of technology to the agriculture business. These efforts include the establishment of Agricultural Technology Research Program in 1973.

Reducing Sound Levels in the Plant

It started with a bang or more accurately, noise. Concerned with mitigating the high levels of equipment noise in poultry processing plants, the Georgia Poultry Federation turned to Georgia Tech for help.

GTRI researchers conducted one of the first definitive studies of the noise environment in a poultry plant. Teaming with NASA, researchers developed sound-absorbing fiberglass panels with a special, high-tech film coating. The coating was capable of withstanding frequent washdowns, while also letting the noise penetrate to the soft, absorptive center. When installed on the ceiling of a plant, the panels reduced sound levels by two orders of magnitude. They were later marketed under the name Sanitary AcousTech Sound Panels.

Through the remainder of the energy-conscious 1970s, the Poultry Federation frequently returned to Georgia Tech with concerns that resulted in several demonstration projects. Much of the research focused on energy efficiency and alternative fuel resources, including wood, solar energy and methane.

Efficient Recovery of Skimmings

In the 1980s, interest shifted to systems development projects dealing primarily with environmental compliance, electronic automation and plant maintenance practices. Agricultural Technology Research Program activities included development of a faster and less expensive way to remove water from a valuable poultry byproduct called skimmings. Speeding up the separation process without adding chemicals was a major enhancement in the efficient recovery of skimmings.

Automating Poultry Inspections

In another project, data entry terminals were networked along a processing line, forming the basis for a tracking system to automate post-mortem poultry inspection. Created by Georgia Tech scientists, the innovative information management project enabled plant personnel, under a U.S. Department of Agriculture initiative, to assist with the inspection procedure. It evolved from a similar Georgia Tech created system for monitoring poultry quality.

A Focus on Applied Technology

Building on the foundation set by its previous work, Agricultural Technology Research Program research from the 1990s to the present has focused on applied technology. Projects are divided into five areas:

"We're pushing the technology frontier and starting to deliver breakthroughs in low-cost imaging, robotics and sensor technologies," said Craig Wyvill, chief of GTRI's Food Processing Technology Division. "We're also involved with some really innovative digital signal processing work, and coming up with software that can discriminate scenes and images to make determinations on good and bad quality features, which is not easy."

Water consumption tops the list of environmental issues of concern to the poultry industry. Researchers are studying water-saving approaches to the rinse cycle in poultry and meat processing, as well as ways to get "the most bang for the buck" with new technologies for wastewater treatment, Wyvill added.

Poultry and Beyond

Other major GTRI projects include:

Poultry processing offers a tremendous and relatively untapped opportunity for the application of technology. GTRI is making these technologies more cost-effective and, therefore, available for other industry sectors.
