ABSTRACT A biodiesel processes from waste cooking oil are consist of a filtration process, a heat treatment of waste cooking oil process, a trans-esterification reaction process, a glycerin-biodiesel separation process, a water cleaning process, and a heat treatment of a biodiesel process. A comparison of an using time between a heat treatment of a biodiesel process at the atmospheric pressure and a heat treatment of a biodiesel process at the vacuum pressure by using a low pressure humidity reducing machine was investigated. From the experiments, the using time for a heat treatment of a biodiesel process at the vacuum pressure by using a low pressure humidity reducing machine was 53 minutes. And also, the using time for a heat treatment of a biodiesel process at atmospheric pressure was 83 minutes. Moreover, the electrical power was decreasing about 16.45 %, for 50 liters biodiesel process with a heat treatment of a biodiesel process at vacuum pressure by using a low pressure humidity reducing machine.
