Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method for combining polished rice and bran, and an apparatus for applying this method t-4.

<Prior art> As disclosed in Japanese Patent Application Laid-Open No. 58-216653 (it is known that the taste of polished rice can be improved by mixing sugar with it and massaging it. The above-mentioned publication suggests the use of an Engel-type rice mill or a thin-throat rice mill, etc. According to the applicant's various experiments, the mixing ratio of sugar to polished rice is 1:1 for polished rice.
It has been found that the ratio of sugar to 0.00 to 15.00 is good. In other words, sugar is 5 to 1 for every 100 parts of white rice.
A small amount of about 5 is sufficient, and when performing the kneading process as described above, it is necessary to mix the sugar in a state in which it is evenly dispersed in the white rice without being concentrated in one place.

(Problems to be Solved by the Invention) However, since the conventional apparatus merely performs stirring and mixing, it is not possible to expect a significant increase in the efficiency of kneading sugar into white rice. Especially in point 02, where the proportion of sugar is equal and a small amount of sugar is mixed with a large amount of white rice.

It has been found that the use of conventional Engel-type rice milling machines, thin-throat rice milling machines, etc. does not provide very satisfactory conditions. Furthermore, although it is necessary to separate the bran from the polished rice after rolling and finish the polished rice as a finished product, no suitable equipment has been found to efficiently carry out the processes of rolling, separating the bran, and polishing the polished rice in a continuous manner. Development of this was desired.

Therefore, in the present invention (first invention), a small amount of rice bran is evenly dispersed and mixed into a large amount of white rice, making it ideal for kneading, removing bran, and polishing. As a method, rice bran is uniformly divided and mixed while supplying polished rice.Next, a cylindrical body with a screw body for kneading that is used for both stirring and transport is placed horizontally in multiple tiers. The cylindrical body and screw body uniformly mix the polished rice and bran while passing through the kneading machine, which has a serpentine shape and is arranged and connected to the kneading machine. A sugar separator connected to the sugar separator is used to separate and take out the milled white rice on the plate, and the white rice is then polished by passing it through a polisher connected to the sugar separator, and the polished rice is made into a product. This is a method of mixing polished rice and bran, which are taken out or circulated again in a mixing machine and later taken out as a product.

Furthermore, in the second invention (second invention), a small amount of rice bran is evenly mixed into a large amount of white rice in a dispersed state, and a second apparatus for feeding white rice is used as an optimal device for mixing, kneading, removing the rice bran, and polishing the rice. A feeding device having a first hopper and a second hopper for supplying plates, and connecting the outlet of a first screw body for feeding bran facing below the opening of the second hopper to the opening of the first hopper, and stirring.・A second screen for both transportation and kneading, with a cylinder that penetrates through the inside, is arranged and connected in a meandering manner horizontally in multiple stages, and its inlet is connected to the fifth
A kneading machine is connected to the supply device via a screw, and a part of the rearmost cylindrical body of the kneading machine is formed of a net, has a plate in the longitudinal direction, and has a second screw body coaxial with the second screw body. A sugar separator in which a three-rotating body is provided with a rotatable body penetrating the inside, and the outside of the net body is surrounded by a hood connected to a suction fan.

A fourth rotating body for both polishing and transfer is provided inside the cylinder, and is connected to the inlet t-1Iff at one end of the cylinder and the outlet of the sugar separator, and has a pressure plate attached to the other end. This is a device for kneading polished rice and bran, which is integrated with a polishing machine provided with a take-out port and connected downward in a t-sequential manner.

Regarding the first invention, if the rice bran is mixed into white rice in equal proportions and placed in a kneading machine, the kneading machine has a serpentine shape as a whole, and the inside is used for stirring and transporting the rice. The cylinders with the screws passing through them are arranged and connected horizontally in multiple stages, so while the cylinders and screws pass through the cylinders, the rice bran and white rice are evenly distributed between the cylinders and the screws. This results in a state of confusion between the two.

Next, the rice bran that has been rubbed in a sugar separator connected to the rubbing machine is separated from the polished rice and taken out, and the polished rice is passed through a polishing machine connected to the sugar separator to be polished. Then, if the polished rice is taken out as a product, or it is circulated again through the mixing machine and taken out as a product later, the bran removal and polishing can be reliably performed following the mixing of the polished rice and bran. become.

(Regarding the second invention) By supplying white rice from a first hopper for supplying polished rice and supplying bran from a second hopper for supplying bran through a first screw body for sending out bran, bran is mixed into polished rice. It can be passed through the third hopper in an evenly divided/mixed state. Then, if the polished rice containing rice bran is put into the massaging machine through this sixth hopper, this massaging machine has a serpentine shape as a whole, and has a second screw body inside which is used for both stirring and transport, passing through the massaging machine. Since a plurality of cylindrical bodies are arranged and connected horizontally in multiple stages, the bran and polished rice are evenly mixed together by the cylindrical bodies and the second screw body while passing through the interior. When is obtained, it becomes K.

Next, the bran and polished rice enter a sugar separator that is connected to the rearmost cylindrical body of the kneading machine. , inside it,
A third rotary body having a plate in the longitudinal direction and coaxial with the second screw body of the strip-laying machine is provided so as to be rotatable therethrough, and the outside of the mesh body is further surrounded by a hood connected to a suction fan. Because of the rotation of this fifth rotating body, the bran comes out from the rice bran after the mixing process is completed through the net, and is separated and taken out into the hood where it is sucked by the suction fan. It will be done. The polished rice is then fed into a polishing machine connected to the outlet of the sugar separator, but here, a fourth rotary body for both polishing and transfer is provided inside the cylinder, so the fourth rotating body The white rice is polished and transferred by the rotation of the body. At this time, since a polished rice outlet with a pressure plate is provided at the end of the polisher, a certain pressure is applied to the polished rice inside the cylinder through the pressure plate, and after the polished rice is sufficiently polished inside the cylinder, the polished rice is taken out. It is called K so that it can be taken out as a product through the mouth.
