1. the method for a continuous solid-state fermentation and product gas-stripping heat-pump integrated separation, described method comprises the following steps:

  • 1) charging stage;

    pulverize solid substances through three grades of spiral conveyer continuously feedings;

    2) fermentation stage;

    fermentation material carries out the circulating gas-lifting solid state fermentation in fermentation tower;

    3) the gas-stripping heat-pump integrated separation stage;

    circulating carried is taken out of behind the tunning through heat pump, and tunning condensation in evaporator with heat pump is reclaimed;

    4) the discharging stage;

    fermentation residue is through one-level spiral conveyer continuous discharge;

    5) the tail gas adsorption stage;

    the unnecessary gas that fermentation produces is discharged through absorbent charcoal adsorber, and the tunning of carrying secretly is adsorbed, and reclaims by desorption again;

    Wherein said step

         1) in three grades of spiral conveyer, first step spiral conveyer (2) plays sealing function in mass transport, second stage spiral conveyer (3) the inoculation fermentation bacterium liquid that in mass transport, has been coupled, add nutritive salt, adjust the pH process, and will inoculate, add nutritive salt, mixing of materials behind the adjustment pH is even, third stage spiral conveyer (4) is sent into material in the tower, to be expected evenly by distributor (5), loose spills in the tower, and material belongs to pre-fermentation or prehydrolysis process in the transmission course of second stage spiral conveyer (3).
