1. continuous solid-state fermentation and the product gas-stripping heat-pump isolating method that is coupled, described method comprises the following steps:

  • 1) charging stage;

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

    2) fermentation stage;

    the fermentation material carries out circulation gas and carries solid state fermentation in fermentation tower;

    3) gas-stripping heat-pump coupling separation phase;

    the circulation carrier gas 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 the continuous discharging of one-level spiral conveyer;

    5) tail gas absorption phase;

    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.
