【発明の詳細な説明】 本発明は、精米装置の改良に係わり、高度精白を能率化
し、しかも美麗な光沢白米を鳩糟するために工夫開発し
たものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the improvement of rice milling equipment, and has been devised and developed in order to streamline high-level milling and to mill beautiful, glossy white rice.

従来、全鳩精工程を通して加湿しながら鳩糟するか、ま
たは鳩精工程のある成分に加湿して鴇糟する実験例はあ
るが、前者は、発生糠の倉水率増加によって糠の腐敗を
招くと共に、白米自体までも添加水のために変質させる
危険があり、光沢白米の対象にはならず実施化されてい
ない。Conventionally, there have been experiments in which the pigeon paste is humidified throughout the entire pigeonseed process, or where a certain component of the pigeonseed process is humidified and added to the rice bran. In addition, there is a risk that the polished rice itself may be deteriorated due to the added water, so it is not applicable to glossy polished rice and has not been put into practice.

また、後者は、単に加湿するだけでは光沢を呈するよう
な美麗な白米を得ることは不可能であった。したがって
、前後者とも無洗米に適合する美麗な光沢白米を鳩糟で
きないものである。一般に摩擦式精米作用では、玄米に
対する歩留９０％程度まで鳩精すると精白能率が急低下
してほとんど進行が停止するので、歩留９０％前後の高
白度の白米を単なる乾式摩擦精米機で鳩精するのは非能
率的である。In addition, in the latter case, it was impossible to obtain glossy and beautiful polished rice simply by humidifying the rice. Therefore, in both cases, it is not possible to produce beautiful glossy white rice that is compatible with no-rinse rice. In general, in friction rice milling, if brown rice is milled to a yield of about 90%, the milling efficiency will drop sharply and the progress will almost stop. It is inefficient to do pigeon sperm.

また、研削式精米作用なら歩留９０％でも、それ以下の
歩留でも無制限に高白度の白米を能率的に鳩糟すること
は容易であるが、その代り白米粒面が粗面質になり、無
光沢の白米になるだけでなく、粒面の窪みに糠層と糠粉
が残留し、斑性白の汚ない白米しか得られない。In addition, with grinding rice polishing, it is easy to efficiently grind white rice with an unlimited number of grains, even if the yield is 90% or even lower. Not only does this result in a matte white rice, but also a layer of bran and bran powder remain in the depressions on the grain surface, resulting in a mottled white and clean white rice.

さらに、従来から糟穀装置の前工程に穀粒冷却装置を設
けたものが、例えば特許第１０３９７６号として知られ
ている。Furthermore, a device in which a grain cooling device is provided in a pre-process of a milling device is known as, for example, Japanese Patent No. 103976.

しかし、このものは、外気を用いる空冷装置によって鳩

遊離糠等を除去するものであって、穀粒面の窪みには依
然として糠層と糠粉が残留しており、無洗米に適合する
光沢白米を得るものではなかつた。However, this method uses an air-cooling device that uses outside air to extract heat from the rice grains that have been heated during the pigeon fertilization process, and removes loose bran etc. Since the rice bran and bran powder remained, it was not possible to obtain glossy white rice suitable for washing-free rice.

ようするに、従来の鶏精法では、タルクコーナィング処
理によって白米粒面に光沢を付与する以外に光沢白米を
求めることは不可能とされている。In other words, in the conventional chicken cleaning method, it is impossible to obtain glossy white rice other than by imparting gloss to the surface of the white rice grains through talc cornering treatment.

とができる光沢米精米装置を提供することを目的とする
ものである。The present invention cools milled rice that has been milled to a corresponding polishing rate in a rice mill without using talc or other brightening agents, and sends it to a milling room where friction milling between grains is performed in a separate friction milling device. During the friction polishing action in the polishing chamber of this friction rice milling device, water vapor is applied to the surface of the polished rice at an appropriate polishing level, and at the same time it is atomized to continue friction polishing, and the rice bran is thoroughly removed through the rice bran removal cylinder. It is an object of the present invention to provide a glossy rice milling device capable of milling beautiful glossy white rice suitable for no-rinse rice by performing a bran removal action.

適温は３０℃以下が光沢発生に有効である。However, the humidifier used to perform this humidification includes moist steam,
A generator such as superheated steam is used, but in principle the temperature of the polished rice during humidification is lower than the temperature of the added moisture, and the added moisture comes into contact with the surface of the low-temperature polished rice grains and dews, resulting in extremely fine particles. The water droplets are applied uniformly to the whole grain of polished rice, and only the very thin surface layer is moistened to make it grainy, and the surface of the rice grain is made smooth by the friction rice bran trochanter, and polished while removing the generated bran, making it difficult to peel off. The bran layer, aleurone layer, and adhering rice bran in the depressions on the grain surface are all removed by polishing, resulting in highly glossy white rice that is evenly polished over the entire surface. According to experiments, the optimum temperature for polished rice during humidification is 30°C or lower, which is effective for producing gloss.

行なう場合もある。When the temperature of rice discharged from the rice milling machine in the preliminary process is rising, it must be heated to an appropriate temperature by a cooling device before being supplied to the humidifying rice milling device. Therefore, when the same polished rice is repeatedly processed in a humidifying rice milling device multiple times, it is necessary to lower the rice temperature each time in a cooling device provided in the process of the humidifying rice milling device. The cooling device used in the present invention uses either liquid cooling or air cooling, and rice milling devices are arranged before and after the cooling device in a series-parallel mixing flow process to accommodate a sufficient amount of polished rice. In some cases, the combination as a whole is a continuous flow process, and the same rice grains may be circulated multiple times through the cooling tank of the cooling device, or the same rice grains may be circulated multiple times in the humidified rice milling equipment installed in the cooling tank. In some cases, the cooling device and the humidifying rice milling device are connected intermittently.

滑面光沢白米が鶏精されるものである。A rice lifting machine 8 installed next to the discharge port 7 of the milling room 3 is connected to a cooling tank 11 containing a freezing pipe 10 connected to a refrigerator 9, and the rice is passed through a tin rice machine 12 installed next to the cooling tank 11. Contact humidifying rice milling machine 13. The humidified rice polishing device 13 has a rice feed port 14.
The hot air generation chamber 15 is connected to the moisture absorption port 17 of the moisture pipe 16 from the hot air generation chamber 15 of the steam generator, and the hot air generation chamber 15 is connected to the metal plate 19 heated by the heating wire 18 from the water supply pipe 21 of the water tank 20 to the control valve 22. A suitable amount of water flows down, generating warm air containing water vapor. The first step in the rice milling chamber 26 between the porous-walled bran removal polishing cylinder 23 and the wind friction milling trochanter 25 constitutes a humidification step 29 in which the inhaled warm air is atomized on the polished rice, and the remaining rice in the milling chamber 26 is The process mainly consists of friction whitening, bran removal, dehumidification and polishing process 26. The jacket 27 surrounding the porous-walled bran polishing cylinder 23 is connected to the bran collector 6 through a bran suction pipe 28. The polished rice, which has been milled from brown to 89% grainy in the milling room 3 and whose temperature has risen to 35 o'clock C, is transferred to the cooling tank 11, and after the temperature has dropped to 20 o'clock, it is passed through the milling room 261 and then passed through the rice feed port 14. 6,000 overflow warm air inhaled from the humidifier is guided to the humidification process 29,
Immediately after the grain surface of the polished rice is moistened and softened by contact condensation, the rice grain surface is moderately moistened and softened, and then the process proceeds to the friction polishing, bran removal, dehumidification and polishing step 24, where the surface is uniformly polished over the entire surface through the various actions of friction polishing, bran removal, dehumidification and polishing. Shiny white rice is made from chicken rice.
