PENGARUH PENYUSUTAN TEMU PUTIH (CURCUMA ZEDOARIA (BERG) ROSCOE) TERHADAP KARAKTERISTIK PENGERINGAN LAPISAN TIPIS
Abstract: The objective of
this study is to analyze the occurrence of shrinkage during thin layer drying
of Temu Putih (Curcuma zedoaria (Berg) Roscoe) and its effects to the drying
characteristics. The experiments were conducted using a laboratory scale dryer
with data acquisition and equipped with machine vision system.The drying
conditions was controlled at temperatures (T) of 50°C, 60°C, 70°C,relative
humidity (RH) 20%,30%, 40%, 50% and air velocity 0.78 m/s – 1.95 m/s with a
specific combinations. The results show that the temu putih’s slices were
shrinking as the moisture content was decreasing with almost linier
correlation.The drying data was used to determine the drying constants using
three models, namely Henderson andPabis, Lewis, and Page model. The effects of
the shrinkage to the drying characteristics is discussed in term of the
relation between surface area ratio (AR) to moisture ratio (MR).
