Device for increasing moisture content of thin-cut expanded shreds

The invention discloses a device for improving the water content of thin-cut expanded shreds. The device comprises an instant electric water heater, a rotor flow meter, a self-circulation water pump, a water storage tank, a pressure reducing valve, a first-stage water pre-adding device, a second-stage water pre-adding device and a moisture regaining cylinder. The first-stage water pre-adding device comprises a first rack and a first cooling conveying belt installed on the first rack, and a first atomizing nozzle and a second atomizing nozzle are arranged above the first cooling conveying belt in the conveying direction in a spaced mode. The second-stage water pre-adding device comprises a second rack and a second cooling conveying belt installed on the second rack. A third atomizing nozzle and a fourth atomizing nozzle are arranged above the second cooling conveying belt in the conveying direction in a spaced mode. An electronic belt scale is arranged below the outlet end of the first cooling conveying belt;
