洗米するものがある。また、この洗米のための通路は横
設されたものであるため、高さ変化のある搬送にはなら
ないので、高さ変化のある次工程に洗米後の米類を搬送
するのに、別の搬送手段を設けている。There is a conventional rice washing apparatus of this type in which rice is continuously fed by using a screw to supply rice washing water while conveying rice. In addition, since the passage for washing rice is installed horizontally, it does not cause a change in height.Therefore, it is necessary to use a separate passage for conveying the rice after washing in the next step where the height changes. A transport means is provided.

【発明が解決しようとする課題】上記従来のような洗米
装置では、米は搬送路をスクリュウにより搬送されるだ
けで、搬送路や米粒どうし、あるいは洗浄液等との接触
効率が悪く、十分な洗浄のためには、長い洗浄経路と長
い時間が必要であるし、米１ｔに対し４ｔ〜５ｔの洗浄
液が必要である。このため、装置およびランニングコス
トが共に高くつく。In the above-mentioned conventional rice washing apparatus, the rice is simply conveyed by the screw in the conveying passage, and the contact efficiency between the conveying passage and the rice grains or the cleaning liquid is poor and sufficient washing is performed. Therefore, a long washing route and a long time are required, and 4 to 5 t of washing liquid is required for 1 t of rice. Therefore, the cost of the device and the running cost are high.

Independently of the rice and the washing liquid, the suction force is applied to the rice washing liquid, especially to the rice washing liquid, by feeding the rice to the discharging pipe side and sending it to the rice feeding pipe in fixed quantity corresponding to the transfer compartment through this discharging port. There is no difference, and the mixing ratio and mixing state of the rice and the washing liquid supplied to the rice / washing liquid introduction pipe are not disturbed, and the mixing of the washing liquid gives fluidity to the rice, and the rice grains and rice grains are sent together with the washing liquid. It is sent smoothly and surely while preventing excessive contact and pressure on the inner surface of the pipe to sufficiently convey the rice to the predetermined position through the rice sending pipe, and is installed in the middle of the rice sending pipe for carrying this. Was The ribbon-shaped twist of the rice guide imparts a swirl to the fed rice and washing water to disturb both under the smooth fluidity and to promote positive mutual contact. Rice can be efficiently washed while transporting rice with almost no generation of rice, and the mixing ratio of the rice washing liquid to the rice supplied to the rice / rice washing liquid introduction pipe is set to about 1: 1 to save water and save rice. It is possible to improve the rice transfer efficiency by increasing the transfer density. In addition, these rice transfers and washings can be achieved simultaneously with the free and simple piping route of the rice transfer pipe, and by using the existing route that transfers rice to the necessary process, it does not take up a special place and is easy. Moreover, it can be realized at a low cost with a small structure. In the configuration in which the rice washing guides in the rice sending pipe are arranged in the longitudinal direction of the rice sending pipe with the twisting directions reversed, the rice washing guide in the previous stage is added to the mixed flow of rice to be sent and the rice washing liquid. Since the swirling flow given by the above is converted into a swirling flow in the opposite direction by the rice washing guide in the latter stage, the rice and the washing liquid can be further disturbed to further improve the rice washing efficiency.
