The refuse processing machine of the invention reduces the bulk of the waste by heating and drying the waste in the waste container by heating means. The grinding and stirring means is operated while heating and drying, and the waste is ground and stirred. The waste is ground into small pieces by the grinding and stirring means, and heat of the heating means is hence smoothly transmitted to the inside of the waste, so that the moisture in the waste may be removed efficiently.

Refuse processing machine

Refuse 21 in a refuse container 2 is heated by a heater 16, and the steam generated from the refuse 21 is condensed by a condenser 8. The ambient temperature near the refuse container 2 is detected by a first temperature detector 6, and the output of the heater 16 is controlled by the output of the first temperature detector 6 so that the temperature near the refuse container 2 may be a specific temperature, and the temperature of the steam flowing out from the refuse container 2 into the condenser 8 is detected by a second temperature detector 7 at the condenser 8. When the temperature change of the second temperature detector 7 exceeds a specific value, the drying process is terminated, so that the drying end time can be detected accurately without allowing to scorch.

Refuse treating apparatus

A catalyst 1 is provided in a gas passage 4 for communicating between a gas flow-in unit 12 and a gas flow-out unit 13, and the catalyst 1 is heated by a heater 2, and a temperature sensor 3 for detecting the temperature of the heater 2 is provided inside the heater 2. By feeding power to the heater 2, the wall temperature of the heater 2 is raised to heat the catalyst 1, and then malodorous gas containing odor substances is passed in from the gas flow-in unit 12. The malodorous gas passes through the catalyst 1 in the gas passage 4 to be oxidized to be harmless and odorless, and is discharged from the gas flow-out unit 13.

Deodorizing apparatus

A catalytic body contains a base material and, formed on the surface thereof, a catalytic coating layer containing activated alumina, zeolite, a platinum group metal and an inorganic binder. By alternately repeating the step of adsorption of odor components with zeolite and alumina under non-heating condition and the step of heat-regeneration of the zeolite and alumina and catalytic decomposition of odor components under heating condition, offensive odors can be continuously removed over a long period and without excessively raising the temperature in the surroundings of the catalytic body.
