(step ST7)
In step ST7, during central control 31 also then continues to the calculating of progress eccentricity (M) under the situation for being more than measurement revolution even at the revolution of roller 2, determine whether eccentricity (M) is less than the dehydration threshold value beta that can not accelerate to highest dehydration revolution.Step is shifted to step ST10 when eccentricity (M) is less than dehydration threshold value beta by central control 31.Step is shifted to step ST8 when eccentricity (M) is dehydration threshold value beta or more by central control 31.
(step ST8)
In step ST8, revolution when central control 31 starts the revolution of roller 2 than in step ST7 reduces the processing of 100rpm.
(step ST9)
In step ST9, central control 31 determines whether roller 2 is decelerated to the revolution set in step ST8.When the 100rpm low revolution of revolution of the central control 31 when the revolution for determining roller 2 is decelerated to than shifting to step ST8 from step ST7, step is shifted into step ST10.
(step ST10)
In step ST10, central control 31 determines whether the revolution of roller 2 is highest dehydration revolution.Step is shifted to step ST13 when the revolution of roller 2 reaches highest dehydration revolution by central control 31.Step is shifted to step ST11 when the revolution of roller 2 is not up to highest dehydration revolution by central control 31.
(step ST11)
In step ST11, central control 31 determines whether the eccentricity (M) of roller 2 is less than as the rising again for revolution that increase the revolution of roller 2 and uses threshold gamma.Step is shifted to step ST12 when the revolution of roller 2 is less than and rises again with threshold gamma by central control 31.Step is shifted to step ST13 when the revolution of roller 2 is to rise again with more than threshold gamma by central control 31.
(step ST12)
In step ST12, the revolution of roller 2 is accelerated to the 800rpm as the highest dehydration revolution in present embodiment by central control 31.
(step ST13)
In step ST13, central control 31 determines whether elapsed time have passed through defined dewatering time after starting dehydration.If starting elapsed time after dehydration have passed through defined dewatering time, central control 31 terminates the processing of dehydration.
In the accelerator for reaching highest dehydration revolution, even once have passed through step ST8, target revolution becomes less than the revolution of highest dehydration revolution, and then in the case where reaching ST13 by step ST12, target revolution becomes maximum number of revolutions.
That is, in the present embodiment, when eccentricity (M) is more than the dehydration threshold value beta as the rotation rising threshold value that increase the revolution of roller 2, increase the revolution of roller 2, continue the rotation of roller up to the stipulated time in dehydration, terminates dehydration.In addition, making revolution rise to highest dehydration revolution if eccentricity (M) is lower than rising again with threshold gamma before the stipulated time, then terminating dehydration.No matter in any situation in these, using step ST13, the time needed for dehydration is not in difference in the present embodiment.
