３）Effectiveness of one time trial
（１）Gross weight at one time trial
Gross weight was an average of 174.7kg in October 1999.
It was the range of 138-213kg by the quantity of a kitchen garbage.
（２）The total amount of kitchen garbages at one time trial
The total amount of kitchen garbages was an average of 120.7kg in October 1999.
It can be processed in 89-161kg.

４）Difference Between One Time Only Trial and Stop and Go trial（batch system）
（１）4 consecutive times
It performed processing 5 minutes or more at 85 degrees C as a standard of an end.
Then, processing was performed 4 times in 4 hours and 30 minutes.
There was little temperature descent according to a raw-material injection by the heat capacity which a machine holds from the 2nd time.
The temperature of 90 degrees C was obtained on the average from the 2nd
time.
It turns out that an effect goes up this equipment more by intermittent
continuation processing.
(２)6 consecutive times
Processing was performed 6 times in 510 minutes.
The average of one processing was 85 minutes.

The amount of processings per hour was 71.3kg of kitchen garbages since
a kitchen garbage is 606kg.

５）Analysis of a Complete Sealed and Insulated Condition
(１)The fermentation temperature of over 100 degrees C.
Temperature became over 100 degrees C by completely sealing.
Temperature reached to 120 degrees C in about 3 hours.
(２)Cultivation at the fermentation temperature of over 100 degrees C.
（Health Sciences Research Institute, Inc）
It sampled and cultivated in normal temperature in order to check whether
it is sterile. However, it not think this time whether it is a fermentation
bacillus.
①At 102 degrees C Bacillus sp.（Aerotropism）、Anaerobiosis（－）、Pathogenic
microbe（－）
②At 110 degrees C Sph. spiritivorum（Aerotropism）、Anaerobiosis（－）、Pathogenic microbe（－）
As expected, it was negativethere and no pathogenicity. It was surprise
that even the fermentation in the situation where it sealed was aerotropism.
However, it can be aerotropism even if it has sealed.
It may reach by 120 degrees C, changing the situation of a bacillus.
③Cultivation sampled in accordance with the temperature rise by the same
fermentation tub
