Penyusunan Skedul Suhu dan Kelembaban Awal untuk Pengeringan di Dalam Tanur Pengering Konvensional bagi Kayu Durian Bersortimen 55 X 195 mm
Abstract: Decreasing supply of
most commercial depterocarp wood as raw material inspirates wood working
industry producing building construction component to look for uncommercial
wood to be utilized. Proper utilization of these woods must be based on wood
properties consisting of wood basic and processing properties. Drying property
is one of the most important wood processing property. Proper drying process
will be the main key to utilize effectively and ensure to get high quality wood
product.
Durian (Durio spp) is one of uncommercial wood grown naturally in
Sulawesi island forest. This wood is used by wood industr to produce building
component to be exported. There is no yet drying schedule formulation of this
wood lumber in dimension of 55mm thick and 195 mm wide. The objective of this
research was to develop drying schedule for durian wood in that dimension.
Drying schedule was developed by the result of quick drying test. The
formulation of drying schedule was elaborated based on Terazawa method.
The research result showed that initial moisture content and specific
gravity of this wood was 103.4% and 0.4 respectively. Theoretically, the first
drying schedule was 54oC as an initial remperature and 80oC as a final
temperature. Web bulb depression for the initial step of drying was 4oC and for
the end step was 30oC. The range of relative himidity were 80% to 17%. These
drying schedule was coded by T5F6.
