The invention discloses a method for rapid propagation of lactic acid bacteria in industrial production, which comprises equipment sterilization, medium preparation and cultivation production; whereinthe equipment sterilization step comprises: S21: placing a preparation barrel, a stirring rod and a breeding barrel in sequence into a sterilization barrel, and placing the sterilization barrel backinto a sterilization pot; the medium preparation comprises the following steps: S12: weighing seasonal vegetables, white sugar, brown sugar, salt, peptone, and dipotassium hydrogen phosphate at mass ratio of 6:1:1:1:1:0.2 for preparation, and placing in the preparation barrel; the cultivation production includes the following steps: S13: taking pure water, brown sugar, white sugar, medium and lactic acid bacteria stock solution at a mass ratio of 90:1:1:0.8:10, wherein the lactic acid bacteria stock solution is used for standby. By setting the equipment sterilization step, the medium preparation step and the cultivation production step, the method for rapid propagation of lactic acid bacteria in industrial production solves the problems that the cost of direct use of the lactic acid bacteria product sold in the market is high, the existing lactic acid bacteria propagation method cannot effectively control foreign bacteria and lactic acid bacteria cannot grow normally.
