Description

[Detailed description of the invention] The present invention relates to a rice polishing device.

Conventionally, rice milling machines that supply moist hot air or moist air to the polishing room are disclosed in Japanese Patent Publication No. 34-46, No. 34-47, Japanese Patent Publication No. 345-345y, and Japanese Patent Publication No. 35-11.
It is publicly known from Publication No. 37 and the like.

However, these methods are used alone, and only polish rice under moist hot air or warm air. Since this process is performed for all the polishing steps up to the present time, improvements in polishing efficiency and polishing effect can be achieved, but there is a drawback that the smoothness of the grain surface of the resulting polished rice is impaired.

In addition, a rice milling machine that can switch the air sent to the milling room between hot air, normal ventilation, and cold/warm air is also known in Japanese Patent Publication No. 33-6802, but this machine can always produce evenly high-quality rice throughout the four seasons. The process is carried out by a single machine, and there is the hassle of having to manually change the condition of the air sent to the milling room depending on the outside air condition during the milling process. has not been carried out,
It is not intended to improve milling efficiency and obtain polished rice with a dense surface and gloss. Therefore, the present invention relates to the improvement of the above-mentioned rice milling equipment, and is devised to accelerate the milling degree and to eliminate the grain of beautiful glossy white rice when the pigeon fertility reaches 94% or more. In other words, without any special manual switching operation, the water heated in the process of 94% or more of porosity, in which the filtration accuracy progresses and the filtration efficiency of the friction filtration action decreases, is heated with hot water, hot and humid air, steam, etc. It is added in the form of water, hot air, steam, etc. to soften the grain structure on the surface of the rice grains, making it easier to peel off the hard layer and increasing the polishing efficiency. It sensitizes the hard starchy surface and creates a dense surface due to the friction between the grains, creating a glossy base while immediately removing the generated sugar and moisture from the sugar-refining tube and polishing. This produces beautiful polished rice with strong luster. In addition, the loss rate as used in the present invention is the ratio of the weight of white rice to the weight of brown rice.

An embodiment of the present invention will be described with reference to the accompanying drawings.
The humidified rice polishing device of the present invention is a friction type rice polishing machine 25 having a dry type rice polishing chamber 1, and a friction type rice polishing trochanter 3 mounted in a rotary type perforated wall sugar removal polishing cylinder 2. A high-temperature humidifying rice milling machine 23 connects a fog generator 5 and a moisture pipe 7 connected to a heater 6 to supply hot air to the milling room 4, and then a blower-type porous-wall sugar removal mill. Friction type whitening trochanter 9 inside white tube 8
It consists of a low-temperature humidifying rice polishing machine 24 connected to a friction type rice polishing chamber 10 which is equipped with a friction type rice polishing chamber 10 and a moisture supply pipe 12 leading to a mist generator 11.

A dry rice milling machine 25 having a dry milling chamber 1 has a supply row 3 and a discharge port 14, and friction milling chambers 4 and 10 each have a supply row 5, 16 and a discharge port 17, 18, and a discharge row 4 and a discharge port 14. The row 5 and the discharge row 7 are connected to the supply row 6, and glossy polished rice is discharged from the discharge port 18.

The blowers 19 and 20 are installed for the wind of the whitening rooms 4 and 10, respectively, and the blowers 21 and 22 are installed as the fog generators 5 and 11, respectively.
The moisture pipes 7 and 12 of As described above, this rice polishing device is configured such that the high temperature humidified rice mill 23 to which humidified heated air is added, uses the high temperature humidified air to polish the surface of the polished rice grains polished by the dry rice mill 25. The grain structure of the rice becomes grainy and the hard layer is easily peeled off, so that the milling efficiency can be increased.Furthermore, the rice discharged from the high-temperature humidifying rice milling machine 23 is conveyed to the low-temperature humidifying rice milling machine 24, Because the rice is milled while adding cold water, the rice is cooled and its structure becomes delicate, and the hard starch on the grain surface becomes slightly softer, and the surface becomes denser due to the friction between the grains, resulting in gloss. While producing the base material, the starch and moisture generated are immediately removed from the sugar-refining barrel and polished.
It produces a strong shine and damages beautiful white rice.

As described above, the present invention achieves highly efficient milling in a very rational manner by arranging an efficiency-oriented high-temperature humidifying rice milling machine and a low-temperature humidifying rice milling machine emphasizing dense surface gloss in relation to the previous and subsequent pigeon milling processes. In addition to being able to achieve the purpose of deep-surface gloss polishing, the high-temperature humidifying rice milling machine is installed in the downstream process of the dry rice milling machine, so the humidification is applied to the polished rice. The surface of the rice can be softened by the moisture, and beautiful polished rice can be obtained without requiring any special manual operations during the rice polishing process.
