Every two hours), each detailed process includes:
All suction hoods 31 are driven to fit with air outlet 13；
Blower 26 is opened, and all valves 28 are opened in turn, and the opening time of each valve 28 is TA (such as 30 seconds), until institute
There is valve 28 to be all previously opened；The effect of this step is in turn to take the hot-air in each chamber 11 away, due at this time only one
Extractor fan 3 can exhausting, therefore its air suction efficiency is high, the hot-air in chamber 11 can preferably be extracted out, make each chamber
Body 11 is cooled down in turn；
Then all valves 28 open simultaneously, duration T B；(such as 1 minute)；All extractor fans 3 can all be taken out at this time
Wind, but blower 26 only has one, so the exhausting ability of each extractor fan 3 is less than previous step, but since most heat is empty
Gas is taken away by previous step, and lesser exhausting remains to lower the temperature in chamber 11 at this time；
Late gate 28 close as follows: when there is 11 temperature of chamber lower than WA, corresponding valve 28 is closed, and works as institute
