Through-Circulation Drying of Vegetable Materials

Potts, Charles S (1957) Through-Circulation Drying of Vegetable Materials. PhD thesis, University of Glasgow.

Abstract

Comparison has been made of the drying properties of five different vegetable materials although variation in piece size and initial moisture content made this difficult. The effect of the following variables on the drying rates of the materials has been discussed ; the nature of the material; the method of preparation and size reduction: the loadings, temperatures, huatdities and air velocities practised; the practicability of agitation of the bad and recirculation of the air; the resistance of the bed to the passage, of air. The accuracy of various methods of predicting drying times and rates has been examined. A graphical method for the design of con inuous multi-stage through circulation driers is presented. Seaweed. The drying characteristics of freshly harvested Ascophyllum nodosum, Fucus vesiculosus and F. serratus have been investigated in a through-circulation dryer. All tests were carried out with minced seaweed. Variables studied were bed depth (0.5-6 in. approx), air temperature (100-220
