Analysis of Palm Shell Mesh Variations with Increasing Productivity of Liquid Smoke Using Air-Cooled Refrigeration Systems

Liquid smoke increases in demand by the community and research is being carried out related to its various benefits, and is environmentally friendly. The raw material in making liquid smoke comes from waste, which can directly minimize the amount of waste in the world. The process of condensing the smoke into liquid smoke has been carried out using conventional water so that there is still a lot of smoke from pyrolysis that has not been condensed. Smoke condensation can be done with controlled low-temperature air. The refrigeration system is used in this study to increase the productivity of liquid smoke. The air temperature used in the smoke condensing process is between 10°C - 0°C for 360 minutes, with variations in the size of palm shell raw materials -3+4 mesh, -4+5 mesh, and -5+6 mesh. The best results were obtained in the smoke condensing process with -5+6 mesh, with the results of 23.26% liquid smoke, 5.16% tar, 61% charcoal, and 6.33% gas, with the yield of 56.18% phenol. These results indicate that the condensing process using low-temperature air is more effective for maximally condensing smoke than conventional water.
