The invention provides an additive metering and cleaning system and stirring equipment comprising the same. The additive metering and cleaning system comprises an additive metering system and a cleaning system, wherein the additive metering system comprises an additive tank and an additive weighing hopper which are communicated with a receiving device through a pipeline in turn; the cleaning system comprises a water supply device and a first water pump which are communicated with the additive weighing hopper through a pipeline in turn; the cleaning system comprises a first water metering system arranged between pipelines of the first water pump and the additive weighing hopper; and the first water metering system comprises a first water weighing hopper, a first water inlet valve arranged on the upstream thereof and a first drain valve arranged on the downstream thereof. The first water metering system is introduced, and the cleaning can be carried out when the additive metering systemis in a working state, so the work efficiency is effectively improved. The stirring equipment comprises the additive metering and cleaning system.
