Biomass (rice husk) as a fuel for sterilizing oyster mushrooms: a case study of fuel efficiency comparison, temperature distribution and production effectiveness

The study on the efficiency of biomass fuel (rice husk) was carried out in the sterilization of oyster mushrooms by using drums as sterilization media and convection pipes as accelerators for heat transfer throughout the sterilization chamber. Variations in diameter and number of convection pipes were used as a comparison in this study. The measurement of thermal temperature was carried out using a thermo laser. In addition, the interpretation of the thermal distribution of the room was analyzed using Surfer software that was performed as a comparison between the number and diameter of convection pipes and determining the distribution of temperature using numeric interpolation. The use of oyster mushroom production using convection pipes 1 rod with a diameter of 8 cm showed the best results, temperature distribution, the efficiency of fuel use in this study. In addition, the comparison of the number of pipes also proved that convection pipes have a temperature distribution that is more equivalent to the number of convection pipes 3 rods. However, the efficiency in the use of fuel using convection pipes 1 rod with a diameter of 6 cm showed a better value than the other.
