Abstract: The objective of this research is to study the influence of wire mesh stainless porous material for Lingzhi mushroom (Ganoderma Lucidum) with hot air drying. Lingzhi mushroom is a drying product and slice at 3 mm thickness. In the experiment LPG burner is a heat source for maintaining hot air temperature at 70 degrees, hot air is flowing through wire mesh stainless porous material at a velocity of 2 m/s before flow into the drying chamber with Pores Per Inch (PPI) is 6, 8 and 12 PPI and wire mesh stainless porous material layer is (WL) 4, 8 and 12 layers. The results are collected in a data logger at intervals of 5 minutes until the final moisture content reaches 12 percent w.b. The variables use in this study are consist of Wet basis moisture content (Mw), Drying rate (R), and Specific energy consumption (SEC). From experimental results, there are shown that the moisture content is decreased, and the drying rate increases with increase PPI and WL and decreases SEC. Drying time is shortest and SEC was lowest at PPI = 8 and WL = 12. The SEC can reduce to 26.18 percent when compared with the drying without wire mesh stainless porous material.
