Abstract

The objective of this research was to investigate appropriate strategies for

spring onion fixed-bed drying. The criteria to be considered in this study were

specific energy consumption, drying time and quality of spring onion. This research

consists of studies of physical properties of spring onion variables which affect

drying rate and the development of mathematical model for strategies of spring

onion drying.

The experimental results of physical properties of spring onion showed that

specific heat of spring onion varied linearly with moisture content and the modified

Halsey’s (Iglesias & Chirife(l51) equation could predict the moisture equilbrium fairly

well for the temperature from 38 oC to 74 OC and the relative humidity of air

from 10 % to 90 % The drying rate of the spring onion was mainly controlled by

internal diffusion. The temperature and velocity of air were the most important

factors which affected the drying rate. Page’s model could predict fairly well as

compared to the experimental results.

Simulated results obtained from the mathematical model indicated that

appropriate strategy for spring onion drying should be as follows: for the frist stage,

air temperature of 80 OC!, specific air flow rate of 33.9 m3/min-kg dry matter and

drying time of 0.5 h, for the second stage, specific air flow rate of 13.5 m3/min-kg

dry matter, the same temperature and drying time and for the final stage(stage 3)

specific air flow rate of 6.8 m3/min-kg dry matter,drying temperature of 72 OC.
