Abstract: The problem
that will be
faced in drying
is quite high
relative humidity, therefore
carrageenan drying process using
spray dryer with
zeolite as humidity
absorber becomes alternative
option to achieve heat
effectiveness of air dryer. The research is purposed to examine the effect of
temperature and level of
zeolite to relative
humidity and product
quality on carrageenan
drying process. Spray dryer
is a dryer used to produce powder material from feeds which have liquid and pasta form. The Results indicate
that humidity and
carrageenan product quality
are influenced by
drying air temperature and
zeolite level. Zeolite absorber will influence humidity. The higher zeolite
level is, the lower humidity will be. when zeolite level 25 cm, the initial relative humidity is about
70%. It will be decrease until 27% and the drying air temperature before heater
gets increase from 28áµ’C to 42áµ’C. The higher drying air temperature and zeolite
level are, the better quality of carrageenan product will be. When drying
air temperature is 90 áµ’C and
zeolite level is
25 cm, moisture
content of carrageenan product is 30,17% and the highest
product efficiency is 68,67%.
Carrageenan product efficiency gets increase by increasing drying air
temperature and zeolite level.
