The invention discloses a fermented condiment intelligent preparation system and method. The fermented condiment intelligent preparation system is characterized by comprising a weighing module, a transmission module, a mashing module, an alarm module, a stirring module, an MCU, a grinding module and a condiment module. The weighing module is used for weighing weight of corresponding condiments. A sensing module is used for sensing that whether the weight of raw materials placed in a container is greater than or equal to a preset value. The MCU controls the transmission module, the mashing module, the alarm module, the stirring module, the grinding module and the condiment module to be connected to perform related operation according to the weighing value and the sensing value through internal judgment and calculation. Effective mashing of the raw materials of the condiments can be performed, the condiments can also be automatically placed according to the proportion, and the raw materials of the condiments and the condiments can be fully stirred so that taste and preparation efficiency of the fermented condiments can be enhanced, manpower resource can be saved and high automation in the preparation process can be realized.
