Abstract

The study aimed to determine the physical and mechanical properties of wood such as moisture, density, specific gravity, shrinkage of wood, modulus of rupture (MOR) and modulus of elasticity (MOE). Parameters also included the moisture content of pizza tray, fuel content, fuel cost, temperature in the fuel compartment, and the temperature in kiln for 3 baking kilns with each kiln baking pizza trays for seven days. It was found that the wood had an average moisture content of 29.26±2.54 percent, a mean density of 618.19±6.42 kg/m3, specific gravity of 0.65±0.06, an average tactile shrinkage of 6.96±0.43 percent, a mean radial shrinkage of 3.67±0.76 percent, and a front cross-sectional shrinkage of 0.38±0.23 percent. After drying, the MOR was 55.07±1.89 MPa and MOE was 5,050.13±24.72 MPa. It was found that the average moisture content of the pizza tray on day 7 was the lowest at around 15.51 percent, the average fuel used during baking was 21.23 kg, the average baking fuel cost was 30.57 Baht, and the temperature used in baking on day 5 had the highest mean at 72.24 oC and the temperature used for baking on day 5 was 84.14oC.
