[0019]

Next, the operation of each of the above means will be described. By the first means, the kitchen waste is crushed by the rotary blade and the fixed blade and is heated and dried up to the central portion, so that it is less likely to rot. Further, during the drying, since it is stirred by the rotary blade, the drying speed is high and there is no unevenness in drying. Then, the dried garbage is roughly crushed to a proper size by the rotary blade and the fixed blade, so that it can be discharged from the discharge port by the scraping action of the rotary blade and the momentum of rotation.

Further, according to the second means, since the crushing is not carried out at two locations at the same time, it is possible to reduce the crushing torque, and the whole valley of the fixed blade is rotated with the rotation of the rotary blade. Since it can be done, the crushing range is not reduced.

Further, according to the third means, only the uncrushed kitchen waste scraped up by the rotary blade is crushed, so that the crushing can be carried out efficiently.

According to the fourth means, by providing the discharge port at a position higher than the deepest part of the drying chamber, the water adhering to the kitchen waste stored in the deep part of the drying chamber and the water released by crushing. Is hard to leak from the outlet. Further, by allowing the rotary blade to rotate forward and backward, the rotary blade is rotated in the direction of the fixed blade from the deepest part of the drying chamber during pulverization to efficiently pulverize, and is rotated in the direction of the discharge port during discharge, It can be discharged efficiently. In addition, the fixed blade does not get in the way when discharging the kitchen waste stored in the deepest part during discharging.

According to the fifth means, the rotational speed of the rotary blade is reduced during stirring to prevent undried kitchen waste from splashing into the drying chamber and sticking to the inner wall, and during discharging, the rotational speed is reduced. Can be increased to increase the momentum of discharge by the rotary blade and enhance the discharge capacity. Since the kitchen waste is dry at the time of discharge, even if it scatters in the drying chamber, it does not stick to the inner wall and is quickly discharged from the discharge port.

Further, according to the sixth means, when crushing various kinds of garbage, the amount and the state of the garbage sandwiched between the rotary blade and the fixed blade are different each time, and the torque required for crushing is also each time. fluctuate. Therefore, if you try to crush 100% of kitchen waste sandwiched between the rotary blade and the fixed blade each time,
A large rated torque is required, but if a torque greater than the preset value is applied to the rotary blade, the rotation direction of the rotary blade is reversed to gradually advance the crushing with a small torque, and when the drying is completed. The crushing can be finished by.
