ABSTRACT:
The present disclosure provides for a system for feeding biomass into a pressured vessel, the system includes a screw-feeding housing, a drive motor, a rotary airlock, a first conveyor screw, a second conveyor screw, a barrel, a low friction liner attached to a substantial portion of the inside surface of the barrel, a pressure sensor positioned within the screw-feeding housing for monitoring backpressure, a compression disk, an actuator, a function controller which controls the pressure sensor, the drive motor and the actuator, and a control loop which comprises the function controller, the actuator, the drive motor, and the pressure sensor for monitoring backpressure within the screw-feeding housing and for controlling and adjusting the force applied by the actuator to the compression disk and the torque applied by the drive motor to the first conveyor screw, thereby effectuating an effectively sealed biomass plug.
