However, the residual moisture of the sludge after dewatering is generally 60

That is, a spiral stirring blade is provided in a cylindrical drying chamber having an inner peripheral surface serving as a heat transfer surface, and the object to be dried (dewatered sludge serving as a raw material for compost) is lifted by rotation of the spiral stirring blade. The object to be dried is dried by repeatedly contacting the object to be dried with the heat transfer surface, and the degree of drying of the object to be dried is detected by a temperature measuring sensor having a temperature measuring unit facing the drying chamber. Such a configuration has been put to practical use.

For this reason, this type of drying apparatus usually determines the required drying time by estimating the residual moisture of the material to be dried by capturing the change in the exhaust gas temperature during drying, and determines the required drying time of the dried material (compost, etc.) I'm trying to get

物の乾燥度合いを検出するような構成となっている。Also, generally, in order to detect the temperature of the exhaust gas, a space near the exhaust port for exhausting the evaporated moisture provided in the upper part of the drying chamber, in other words, in the drying chamber, A temperature measuring sensor such as a thermocouple is provided at an upper position where it does not come into contact with an object so as to face the temperature measuring unit to detect the degree of drying of the object to be dried.

形成してしまう。However, as described above, when a temperature measuring sensor is provided so as to face the temperature measuring section near the exhaust port above the drying chamber, dust or fibrous material discharged from the material to be dried over a long period of operation. Foreign matter adheres to the temperature measuring section and forms a heat insulating layer.

のとなっていた。[0007] Due to the formation of the heat insulating layer, an error occurs between the actual exhaust temperature and the temperature indicated by the temperature measurement sensor.
In addition, since the amount of the error is not constant depending on the degree of adhesion of the foreign matter to the temperature measuring unit, the correction is not effective, and therefore, the residual moisture amount of the object to be dried varies, which is difficult to manage. .

いものであった。As described above, in a drying apparatus in which the degree of drying of the object to be dried is detected by a conventional temperature measuring sensor, dust or fiber is added to the temperature measuring section of the temperature measuring sensor. In some cases, the temperature-measuring sensor cannot accurately detect the exhaust temperature due to the attachment of the foreign matter and the degree of adhesion of the foreign matter, and therefore, the dried matter having a predetermined residual moisture (in this embodiment, In order to obtain (compost), it is not always sufficient in terms of manageability, for example, it is necessary to arrange and manage experienced workers.
