White spirit filtering method and automatic system for filtering white spirit

The invention relates to a white spirit filtering method and an automatic system for white spirit filtering. According to the method, diatomite is used for filtering white spirit, and the method comprises an initialization stage and a steady-state working stage. The initialization stage comprises the following steps: proportionally adding diatomite with two granularities into a diatomite adding tank, and stirring for a preset time period, wherein the adding weight of the diatomite is that the diatomite is added according to the volume of the base wine in the diatomite adding tank according to a preset proportion; inputting the stirred base liquor containing the diatomite with at least two granularities into a candle filter, so that the diatomite can be adsorbed on a filter column of the candle filter; and monitoring the turbidity of the wine liquid at the outlet of the candle filter, completing the initialization stage under the condition that the turbidity is lower than a preset threshold value, and filterin
