<p>PURPOSE:To make the amount of exhausting air constant regardless of the magnitude of a hot air temperature, by controlling the mixture of the used hot air, which is sent to a deodorizing chamber by an odor blower and processed high temperature air so that the temperature of the mixture becomes a preset constant temperature. CONSTITUTION:The temperature of a used hot air 4', which is sent to an odor collecting chamber 15, is 150-200 deg.C. Meanwhile the temperature of high temperature air 31 is about 350 deg.C. When the temperature of the mixture, which is obtained by mixing both airs, is lower than a preset value TS, a temperature adjusting meter 33 sends a signal to a control motor 29, adjusts the opening degree of a damper 30, and increased the hot temperature air 31. Conversely, when the temperature of the mixture is higher than the preset value TS, the opening degree is controlled so that the amount of the hot temperature air 31 is decreased. As a result, the temperature of the air, which is sent to deodorizing chamber 7 by an odor blower 17, becomes the constant value TS.</p> |
