PEMANFAATAN ZEOLIT ALAM UNTUK PENGERINGAN KARAGINAN DENGAN SPRAY DRYER

Edit
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.
