The invention provides a multi-channel metering machine. The multi-channel metering machine comprises a lifting tilter for lifting to-be-weighed materials and pouring the materials into a storage bin,multiple discharge ports are formed in the bottom of the storage bin, a roller material supply mechanism is arranged below each discharge port of the storage bin, metering hoppers are arranged belowthe roller material supply mechanisms, material cups capable of sliding on a transfer mechanism are arranged below the qualified material discharge ports of the metering hoppers, and chutes are formedbelow the disqualified material discharge ports of the metering hoppers. The weighing metering efficiency and the weighing metering precision can be improved, and meanwhile the safety and the environmental protection of production environments are guaranteed.
