Design and Control of Energy Efficient Drying Processes with Specific Reference to Foods (Quarterly Report for the Period July 1, 1987-October 1,1987)
- Purdue Univ., West Lafayette, IN (United States)
Work on Phase 2 of the drying project was started during the last quarter. Progress on Task 10 (Revision of Drying Models) included a review of fundamental drying theory, and an investigation of experimental methods to determine model coefficients. Models for a drum dryer were also analyzed this quarter. Progress on Task 11 (Dryer Studies) included an analysis of a pressurized drying chamber, and installation of a vacuum drum dryer. Further work is needed to prepare both systems for experimental drying studies. Progress on Task 12 (Food Quality Studies) included collection of data on browning and vitamin A degradation in nonfat dried milk. Analysis and interpretation of the data are planned for the next quarter. Thermal property tests on porous food materials were also investigated during the past quarter. Progress on Task 13 (Recommendations/Strategies for Dryer Design and Control) included a review of dryer control strategies presented in the literature. A survey of available sensors for dryer control is planned for the next quarter.
