Description
【考案の詳細な説明】 本考案は、製茶蒸機用の蒸気温度測定装置に関する。[Detailed explanation of the idea] The present invention relates to a steam temperature measuring device for a tea steamer.
製茶工程では、茶生葉の性質や外気温等に応じて蒸機へ
供給する蒸気の温度、湿度を変える必要があるため、蒸
機へ供給する蒸気の管理はことのほか重量になる。In the tea manufacturing process, it is necessary to change the temperature and humidity of the steam supplied to the steamer depending on the properties of the green tea leaves and the outside temperature, so managing the steam supplied to the steamer is particularly important.
ところが、この工程では、茶葉に接した際、数秒から数
１０秒で凝縮するような低圧、低温の蒸気が使用される
関係上、この蒸気が管路内の温度計等に接触した場合急
速に凝縮して温度を下げるため、検出温度が実際のもの
より低くなってしまうといった問題を抱えている。However, this process uses low-pressure, low-temperature steam that condenses in a few seconds to several tens of seconds when it comes into contact with tea leaves, so if this steam comes into contact with a thermometer in the pipe, it will quickly condense. The problem is that the detected temperature is lower than the actual temperature because it condenses and lowers the temperature.
本考案はかかる問題に鑑み、蒸機へ供給される蒸気の温
度を正確に測定することのできる改良された温度測定装
置を提供することを目的とするもので、以下に本考案の
詳細を図示した実施例に基づいて説明する。In view of this problem, the present invention aims to provide an improved temperature measuring device that can accurately measure the temperature of steam supplied to a steamer.The details of the present invention are illustrated below. An explanation will be given based on an example.

壁には受座１０ａが形成されている。FIG. 1 shows an electric temperature sensing element 5 which is an embodiment of the present invention, where 31 is a pipe wall of a pipe line 3 leading from a boiler to a steamer, and 10 is a temperature measuring element that penetrates the pipe wall 31. A hot body mounting tube has a seat 10a formed on its inner wall.

が、このスリーブ５１に囲まれた空間に位置している。Reference numeral 51 denotes a sleeve that covers the temperature detection element 52 located in the pipe line 3. This sleeve 51 has a 500-700 mesh (hole size 20 mm) that allows only steam to pass through.
．． ), the detection element 52 at the tip of the lead wire is fixed by filling it with heat-resistant resin 53.
is located in a space surrounded by this sleeve 51.
また、このスリーブ５１の外周には段部５４が形成され

It is fixed at 10.

正確な蒸気温度が検出される。In the above-described embodiment, the steam containing minute water droplets generated in the boiler flows toward the steamer at a speed of about 40 m/s in the pipe 3, and the The temperature is detected by the detection element 52, but since the sleeve 51 described above is composed of a mesh through which only steam passes, minute water droplets cannot enter into the sleeve 51. There is no need to cool down and detect a temperature lower than the steam temperature.
Accurate steam temperature is detected.

ための状態を作り出すことができる。As described above, according to the present invention, the temperature detection element is provided protrudingly in the passage of steam leading to the steamer, and the temperature detection element is surrounded by a mesh body, so that the temperature detection element is covered by the mesh body. This prevents the temperature of the detection element from decreasing due to condensation of steam, and also slows down and uniformizes the speed of the steam that has entered the interior through the mesh, allowing it to reach the detection element. Conditions can always be created for accurate steam temperature detection.
