Bio-ethanol Generator that helps farmers produce bio ethanol fuel by themselves converts the fruits or crops that don't have economic value that are eliminated by farmers into biomass fuels. Bio-ethanol Generator uses the manufacturing method to increase the output efficiency of fuel, and can know whether raw materials and chemical agents need to be added through the return data. The produced biomass alcohol can be added into the car to mix into appropriate biomass fuel to reduce carbon emissions and the problem of excessive leftover food and achieve an effective circulation system.
