S40205: discharge: when after the time through a feeding study on period, blower fan current reduction amplitude less than its rated current 4% time, no longer carry out supplementing feeding in raw material, when in machine, material water ratio meets the requirements, open the blow-off valve on cyclone dust extractor and the blow-off valve in cleaner unit branch road discharge threeway and close adjustment valve, material in machine is discharged；
In machine material drained after, open adjustment valve to former aperture, the blow-off valve on closedown cyclone dust extractor and the blow-off valve in cleaner unit branch road discharge threeway, re-start S401, S40204, S40205, such iterative cycles operation successively；
S403, technological parameter regulate:
S30301, control enter cleaner unit branch road material moisture content, do not adhere to as principle on sack cleaner cloth bag with it；Regulate rotation speed of fan, atomization quality, charging rate, feeding quantity, change cyclone dust extractor ash discharging hole diameter can regulate enter cleaner unit branch road material moisture content,
S40302, back-blowing device regulate: observe the pressure condition of cleaner unit branch road, the blowback cycle of timely adjustment back-blowing device, blowback time and blowback bleed pressure in operation process, make pressure in cleaner unit branch road be in alap state；
S40303, goods fluid state adjustment: operation process observes the fluidized state of material, regulates rotation speed of fan and feeding quantity so that material is in good fluidized state；
S40304, air heater heat outputting air temperature adjustment, operation process is observed the state of temperature in malleation circulation pipe I, adjusts the hot blast temperature of air heater output to be at less than 60 DEG C in good time；When air heater stop heating can't by malleation circulation pipe I in temperature control less than 60 DEG C time, reduce rotation speed of fan, the minimizing heat that is transformed of blower fan kinetic energy is controlled；
When needing to reduce rotation speed of fan to control the temperature in malleation circulation pipe I, illustrate that dry run early has been enter into the falling-rate periods of drying phase, in this opportunity, the moisture content of material is general lower than 15%, and the fluidizing performance of material improves, it is not necessary to too high wind speed can form good fluidized state；
The judgement of moisture in S40305, material: present device rate of drying quickly, to such an extent as to be can't wait and determined the moisture content of material in machine by sampling detection；After operation process enters deceleration drying section, built-in temperature can go up gradually, humidity then constantly reduces, by the comparative observation of diverse location temperature, humidity and blower fan electric current, feeding quantity and discharge material water ratio in the air-flow that cleaner unit branch road is discharged and machine, the mapping relations of material water ratio and temperature, humidity and blower fan electric current, feeding quantity in machine can be obtained, by the moisture content of material in this relation judgement machine；When in machine, material water ratio reaches requirement, dry；
S5, shutdown: after operation completes; open the blow-off valve on cyclone dust extractor; regulating rotation speed of fan makes blower fan operating current to the 100% of rated current; circulation canal is purged 10 minutes with maximum wind velocity; purging complete after regulate fan power frequency identical with frequency of supply after close blower fan, heater, molecule valve exsiccator, back-blowing device; blow-off valve on cyclone dust extractor, the blow-off valve in discharge threeway, shutdown of cutting off the electricity supply.
