Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rice milling apparatus for obtaining ultra-shiny unwashed polished rice.

In order to obtain ultra-shiny polished rice that does not require washing with water before cooking and is free of bran adhesion, a rice polishing device in which the discharge section of a humidified frictional rice miller is connected to the supply section of a rice polishing machine has already been proposed.

However, conventional rice polishing machines simply pass polished rice through a rotating drum for polishing rice, or use a rice polishing cylinder that is rotatably disposed inside the rice polishing cylinder and has a flexible material on its surface. Polished rice is passed between the rice trochanter and the former, the polishing effect on the surface of the polished rice is too weak, and the latter has a polishing effect on the surface of the polished rice that changes due to the flexible material. The flexible material was worn to a large extent, and proper rice polishing action could not be sustained, making it impossible to obtain the desired ultra-glossy, unwashed polished rice.

It is an object of the present invention to provide a rice polishing apparatus that eliminates the above-mentioned drawbacks, allows proper rice polishing to be carried out over a long period of time, and is capable of obtaining ultra-shiny, unwashed polished rice.

In order to achieve this objective, the rice polishing device of the present invention is a rice polishing device in which a rice polishing discharge part of a humidified friction rice polishing machine is connected to a supply part of a rice polishing machine, and the rice polishing machine has a spiral protrusion in a porous wall polished rice cylinder. It is characterized by the arrangement of a polished trochanter.

Embodiments of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a humidified friction rice polishing machine, which has upper and lower perforated wall polishing cylinders 2, 2, and inside these perforated wall polishing cylinders 2, 2, friction polishing trochanters 4, 4 having protrusions 3, 3 in the axial direction are installed. It is arranged so that it can rotate freely.

The friction whitening trochanters 4, 4 have long grooves 5, 5 formed along the protrusions 3, 3, and these long grooves 5, 5 communicate with the mist generating nozzles 7, 7 via hollow whitening trochanter shafts 6, 6. are doing. The fog generating nozzles 7, 7 are connected to a water tank 8 and an air compressor 9, respectively. 10
1 is a rice grain supply section, 11 is a rice grain discharge section, and 18 is a screw conveyor that connects the upper porous wall polishing tube 2 and the lower porous wall polishing tube 2.

12 is a rice polishing machine, with perforated rice polishing cylinders 13 and 1 on the top and bottom.
3, and polishing rice trochanters 15, 15 provided with spiral protrusions 14, 14 are rotatably arranged inside the porous-walled rice polishing cylinders 13, 13.

Reference numeral 16 denotes a rice grain supply section, which is connected to the discharge section 11 of the humidified friction rice mill 1 via a grain lifting machine 17. 19
is the discharge part of the rice polishing machine.

Next, to explain the operation, polished rice with a yield of 94% or less is supplied from the rice grain supply section 10 of the humidified friction rice milling machine 1, and is passed through the nozzle 7 by the water tank 8 and air compressor 9 to the friction milling trochanter 4, 4. Supply humidified air into the room. This water addition is carried out in a range of 0.1 to 2% based on the amount of rice, and humidified air is supplied into the porous wall polishing cylinder 2 from the long grooves 5, 5 of the friction polishing trochanters 4, 4, and is supplied from the supply section 10. Moistens only the surface of polished rice,
The surface of the polished rice softens and immediately generates bran due to the polishing action, and the bran and water are simultaneously expelled from the polishing barrel through the porous-walled polishing barrel. Since this bran has a high starch content, there is less adhesion of bran to the surface of the polished rice grain, making it easier to remove the bran.Additional moisture is not absorbed and permeated into the inner substance of the rice grain, so the inner substance of the rice grain is protected, and the rice grain remains moist. The surface is smoothed by the mutual friction between the grains, giving the surface of the polished rice grains a strong luster. In this way, the polished rice that has been given luster by the upper friction polishing trochanter 4 is further conveyed by the screw conveyor 18 to the porous wall polishing tube 2 located further below, where it is further given luster by the same humidified friction polishing action. The rice grains are then discharged from the rice grain discharge section 11.

The glossy polished rice discharged from the rice grain discharge section 11 of the humidified friction rice milling machine 1 is sent to the rice polishing machine 12 by the grain lifting machine 17.
is sent to the supply section 16 of.

The polished polished rice sent to the supply section 16 of the rice polishing machine 12 is fed by the spiral protrusion 14 of the rice polishing trochanter 15 inside the porous-walled rice polishing tube 13 of the rice polishing machine 12, and is sent to the discharge section 19, 19 and is ejected from the aircraft.

At this time, the polished rice between the spiral protrusions 14 of the polished rice trochanter 15 receives appropriate friction with the polished rice trochanter 15 and friction between the polished rice, and furthermore, the polished rice between the polished rice trochanter 15 and the porous wall The polished rice between the rice cylinder 13 and the rice polishing tube 13 is sequentially rubbed by the polished rice fed between the spiral protrusions 14 of the rice polishing trochanter 15, and is further rubbed by the polished rice fed by the spiral protrusions 14. 13, and in this way, by the rice polishing machine 12, the glossy polished rice is properly friction-polished by the polished rice, by the polishing trochanter 15, and by the porous-walled rice polishing tube 13, and a small amount of rice is generated. The bran is removed to the outside from the porous-wall polished rice cylinder 13, resulting in ultra-shiny unwashed white rice.

As described above, the rice polishing device of the present invention is a rice polishing device in which the rice polishing discharge part of the humidified friction rice polishing machine is connected to the supply part of the rice polishing machine, and the rice polishing machine forms spiral protrusions in the porous wall polished rice cylinder. This rice polishing machine is characterized by the arrangement of a polished rice trochanter, so the glossy polished rice obtained by the humidified friction rice polishing machine becomes ultra-glossy unwashed polished rice in the rice polishing machine, and this rice polishing machine Since the rice polishing trochanter with spiral protrusions is placed inside the porous wall rice cylinder,
Unlike a friction rice polishing machine with friction ridges installed parallel to the rotating shaft, it does not generate large frictional force, but uses a small frictional force close to the screw conveyor to properly polish the surface of glossy polished rice and achieve the desired finish. You can get super glossy unwashed white rice, and the polished rice trochanter is durable.
This allows for uniform polishing work.
