Solid-state fermentation method for white spirit

The invention discloses a solid-state fermentation method for white spirit. The method comprises the following steps: step 1, preparing raw materials; step 2, temperature and humidity monitoring; step 3, steaming; step 4, cooling; step 5, primary fermentation; step 6, primary cellar loading; step 7, performing secondary fermentation; step 8, secondary cellar loading; step 9, distilling; according to the solid-state fermentation method for the white spirit, the water content of the raw materials is increased by setting two-time material moistening operation, the crushed and impurity-removed raw materials are mixed with the fermented grains, so that the raw materials can absorb some moisture and organic acids from the fermented grains to facilitate gelatinization, and the steaming time is determined by monitoring the temperature and humidity of the raw materials after one-time material moistening; and during steaming, secondary material moistening is needed, so that the wetting degree of the raw materials is fu
