A fluid discharge system and the squeezer, where the squeezer includes a pair of rollers, a driving device, and a mounting bracket. The pair of rolling shafts is rotatably mounted to the mounting bracket, and each rolling shaft has a mounting parts at both ends and a squeezing segment between the mounting parts. The squeezing segment includes a supporting shaft and an elastic body provided around the supporting shaft. A pair of rolling shafts can operatively clamp the object to be clamped between the squeezing segments and can rotate oppositely through a driving device to apply a squeezing force to the clamped object. The driving device includes a motor, wherein the motor is mounted around the rolling shaft. The fluid discharge system and the squeezer are a zero-residue discharge system without liner suspension, have a long effective squeezing length, and are easy to operate.
