Method for producing different grades of alcohol by multi-tower distillation

The invention relates to the technical field of alcohol, in particular to a method for producing different grades of alcohol through multi-tower distillation, which comprises the following steps: S1, material preparation: washing wine brewing raw materials, sterilizing in a boiling water pool, and then drying water; s2, carrying out multiple rounds of continuous fermentation by adopting a continuous slag batching and mixed steaming and mixed burning mode; s3, collecting the white spirit generated by distillation in S2 through a collecting device, and storing the collected white spirit in a storage tank; s4, multi-grade alcohol distillation is carried out in the mode that multiple stages of distillation towers are connected in series and controlled through valves; s5, quality control: detecting products such as alcohol generated in the multi-stage distillation mode; and S6, product packaging, wherein the product is cooled through a pipeline and guided into a storage tank. According to the method for producing
