8.9. APPLICATIONS IN FOOD INDUSTRY

Intense ever increasing international competition and process economics with as-
surance of quality is the main driving force behind the study of industrial drying
processes in food industries. Statistical design techniques can offer wide range of expe-
rimental designs to a broad range of industrial drying problems. Table 8. 3 enlists vari-
