(1) ight soil imports: be ready to the breed ight soil of pending fermentative processing, by opening for feed 1 and the feed-pipe 5 that links to each other with opening for feed 1, feed and ferment cavity volume to the first fermentation cavity volume and second of fermentation unit body culturing ight soil, close discharge port 6; Begin to start first transmission mechanism 7 and second transmission mechanism 8, make it drive first fermentor tank 2 and 3 rotations of second fermentor tank respectively; At this moment, control first fermentor tank 2 and second fermentor tank 3 carries out incorgruous rotation, fermentation materials such as ight soil in the first fermentation cavity volume and the second fermentation cavity volume are under the stirring of circular knife 14 drives, constantly assemble to the middle part from the both sides of fermentation unit, by rotation stirring constantly, fermentation materials is able to abundant mixing and can derive from discharge port 6.
(2) ight soil deactivation: close discharge port 6, microbial solution by-pass valve control 15 and scavenging solution by-pass valve control 16 etc., by regulating temperature regulator 9, the temperature of the first fermentation cavity volume in the fermentation unit body and the second fermentation cavity volume is heated to about 121 ℃, meanwhile, Sustainable Control first fermentor tank 2 and second fermentor tank 3 carry out incorgruous rotation, make fermentation materials carry out sufficient deactivation, sterilization under this environment; This deactivation, sterilization process about 30min(consuming time are generally 20min～40min).
(3) fermentation is prepared: stop the rotation of first fermentor tank 2 and second fermentor tank 3 after the ight soil inactivation process finishes, culturing ight soil cools off gradually, continue to close scavenging solution by-pass valve control 16 this moment, but open microbial solution by-pass valve control 15 simultaneously, squeeze into aerobic type microbial solution by volume pump in the microbial solution fluid inlet 12 and (can squeeze into dissimilar microbial solutions according to the difference of fermentation condition, what present embodiment was squeezed into is the EM bacterium liquid that is exclusively used in manure fermentation, this EM bacterium liquid is commercially available), and by sparge pipe 11 microbial solution of squeezing into evenly is ejected on the intrinsic fermentation materials of fermentation unit, restart first transmission mechanism 7 and second transmission mechanism 8 of fermentation unit body before the hydrojet, make first fermentor tank 2 and second fermentor tank 3 carry out incorgruous rotation, the rotation that keeps tank body during hydrojet, so that microbial solution can evenly spray on fermentation materials, after intact by setting dosage hydrojet, close microbial solution by-pass valve control 15; Evenly be laid with jet hole (referring to Fig. 5) on the tube wall of sparge pipe 11, be ejected into the intrinsic microbial solution of fermentation unit and can guarantee carrying out smoothly of follow-up high-temperature aerobic fermentation process better.
(4) fermentation culture: begin after hydrojet is finished to ferment, tank body keeps incorgruous rotation until fermentation ends, and rotating speed generally is no more than 60 r/min; Under the effect of circular knife 14, the tank body of the rotation fermentation materials that constantly stirs, pushes, rolls; Open air-vent 4 this moment, utilizes induced draft fan that the waste gas in the fermentation unit is taken out and draw, and is delivered to wet dust collector after the waste gas that fermentation produces is drawn and handles; Opening for feed 1 also is held open state and (uses as blast inlet, the blast inlet place can arrange air purifying filter core, can intercept airborne particulate matter and microorganism), make the air in the fermentation unit form convection current, to guarantee having fresh Tempeerature-constant air constantly to enter in the fermentation unit, guarantee that the high-temperature aerobic fermentation process is to the demand of oxygen.Meanwhile, by adjusting temperature regulator 9, the temperature of fermentation unit chamber body is controlled at 55 ℃～60 ℃, and opened humidity regulator 10, the humidity of fermentation unit chamber body is controlled at water ratio 55%～65%; When showing that humidity reduces on the humidity regulator 10, start the cleaning function of sparge pipe 11, open scavenging solution by-pass valve control 16, close microbial solution by-pass valve control 15, in fermentation unit, spray clear water to improve the humidity of fermentation unit inner chamber; If humidity regulator 10 shows when humidity is excessive, then by the moisture evaporation effect in the fermenting process, the recycling induced draft fan is taken out unnecessary water vapour and is drawn fermentation unit, to reach the purpose that reduces humidity, so just can guarantee the basic demand that fermentation unit is controlled humidity during the fermentation.The duration of whole high-temperature aerobic fermentation process is approximately 12h～24h.
(5) discharging: after above-mentioned high-temperature aerobic fermentation was finished, breed ight soil was wherein fully become thoroughly decomposed; Closing temperature controller 9 and humidity regulator 10 are closed each valve simultaneously, stop the air inducing at air-vent 4 places, stop the incorgruous rotation of first fermentor tank 2 and second fermentor tank 3.Restart first transmission mechanism 7 and second transmission mechanism 8 by control device, and make first fermentor tank 2 and second fermentor tank 3 keep rotation in the same way, rely on drive and the stirring action of inner chamber circular knife 14 again, the breed ight soil that will become thoroughly decomposed is passed to discharge port 6 gradually, realizes the discharging of fermentation materials in the fermentation unit.
