Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a rice polishing machine.

(Prior Art) A rice milling machine includes a pressure type rice milling machine in which rice is applied by applying pressure so that paddy or brown rice is rubbed against each other. This pressure rice mill has a structure in which a screw roll is placed inside a cylinder installed horizontally at the bottom of the hopper, and the paddy or brown rice dropped from the hopper into the cylinder is rotated forward by rotating the screw roll. It is pumped and pressure is applied to the paddy or brown rice to polish the rice.

Rice husks and bran are produced during rice milling.The methods of discharging the rice husks and bran are as follows: the peeled rice husks and bran are discharged directly to the outside of the rice milling machine, and the rice bran box is placed inside the rice milling machine to receive the rice husks and bran. There are those that are dropped in the box, and those that are equipped with a suction fan to suck the rice husks and bran and discharge them outside the rice milling machine and store them in a bran bag, bran box or the like.

In the rice bran box provided in the above-mentioned rice milling machine, the lower half of the cylinder in which the screw roll rotates is formed by the bran removal mesh, and the rice husk and the bran are formed so as to fall from the bran removal network into the bran box. ing.

(Problems to be solved by the invention) In the type of rice milling machine equipped with a bran box in the main body, as described above, the peeled rice hulls and bran are formed so as to fall into the bran box through the bran removal mesh. However, in the past, rice husks and bran were simply allowed to naturally fall and fall into the bran box, so that the rice husks and bran that fall from the mesh of the bran removal mesh are scattered to clean the rice mill. There was a problem.

This is because the screw roll rotates at a considerably high speed, and the rice husks or bran are scattered to a considerable extent.

Therefore, the present invention has been made to solve the above problems, and its purpose is to provide a rice milling machine of a type in which a rice bran box is housed in the rice milling machine, in which rice hulls or bran are scattered. The present invention intends to provide a rice milling machine that prevents rice bran from falling into the rice bran box and can surely store rice hulls or bran in the rice bran box.

(Means for Solving the Problems) The present invention has the following configuration in order to achieve the above object.

That is, the present invention provides a screw roll for pumping the rice or brown rice supplied from the hopper to polish the rice, a bran removal net for separating the rice husk and bran generated during the polishing by covering the screw roll from the milled rice, and a bran removal bran. In a rice mill having a bran box housed in the main body below the net, a blower port opening toward the outer peripheral surface of the bran removal net and cooling air from the blower port to the outer peripheral surface of the bran removal net. A fan for blowing, a cover portion for covering the bran box so that the bran removal net and the blower opening are included, and a cooling introduced by the fan into a space closed by the bran box and the cover portion. And a filter provided so that air can be exhausted and bran or the like does not scatter.

(Operation) During rice polishing, rice or brown rice is pumped by a screw roll to exfoliate the rice husk or bran, and the exfoliated rice husk or bran falls into the bran box through the bran removal net. At this time, the cooling air is blown to the outer peripheral surface of the bran removal mesh by the fan. The bran removal net is enclosed in the space closed by the bran box and the cover, so that cooling air is blown, but the dehulled rice husks and bran fall into the bran box without fail, and outside the bran box. Do not scatter on. Then, the cooling air introduced into the closed space is exhausted through the filter.

(Embodiment) A preferred embodiment of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is an explanatory view showing a main part of a rice polishing machine according to the present invention, and FIG. 2 is a side view of the main part.

There are two types of rice polishing machines, one is a circulation type in which paddy or brown rice is circulated to polish rice, and the other is a single-pass type in which rice is polished only once.

In FIG. 1, 10 is a bran box that is housed in the body of the rice milling machine, and this bran box 10 is formed in a box shape with only the upper part opened. Bran Box 10
Is formed so that it can be drawn in and out from the rice milling machine body.

12 is a screw roll for pumping and polishing white rice or brown rice, 14 is a frame that covers and covers the upper half of the screw roll in a semi-cylindrical shape, and 16 is a semi-cylindrical bran that covers the lower half of the screw roll 12. It is a net. Reference numeral 19 is a net receiving frame for fixing the side edge of the bran removal net 16 to the side edge of the frame 14.

A cover 18 is extended from both side edges of the frame 14 so as to cover the bran box 10 following the frame, and a peripheral portion of the cover 18 is formed in a lid shape bent downward.

The cover 18 is formed by fitting with the upper edge of the bran box 10 so as to completely close the upper part of the bran box 10 when the bran box 10 is housed in the main body of the rice polishing machine. Frame 14 and cover like this
The bran box 10 is covered by a cover part having 18 as a component so that the bran removal net 16 is contained therein.

Reference numeral 20 denotes a filter that shields an opening provided on the upper surface of the cover 18, and serves to act as an air vent capable of exhausting cooling air introduced by a cooling fin described later.

As shown in FIG. 1 and FIG. 2, the bran box 10 is located almost directly below the screw roll 12, and in the state where the bran box 10 is accommodated, a cover portion having a cover 18 and a frame 14 as constituent elements,
The bran box (10) forms a closed space around the bran removal net (16) where rice husks or bran are accumulated.

FIG. 3 is an explanatory view showing an embodiment of a rice polishing machine in which the bran box 10 is installed.

In the figure, 30 is a hopper for introducing paddy or brown rice to be milled, and a drop opening 32 for dropping the paddy or brown rice from the hopper 30 to the milled rice portion is provided at one end of the bottom portion.

Reference numeral 34 is an introduction path extending obliquely downward from the outlet 32, the lower end of which communicates with the rice polishing section. Reference numeral 36 is an outside air introduction port that opens to the outside of the hopper 30 at the upper part of the introduction path 34.

The screw roll 12 is laterally supported at the lower end of the introduction path 34, and is linked to a rotation drive unit via a pulley 38. The screw roll 12 consists of three parts, and a feed roll that feeds paddy and brown rice forward in the part facing the lower end opening of the introduction path 34.
12a is provided, and a polishing blade 12b for exfoliating the bran is provided in the middle part.
And a whitening roll 12c at the front end.

A spiral for pressure-feeding paddy or brown rice is formed on the outer peripheral surfaces of the feed roll 12a and the whitening roll 12c, and the polishing blade 12b is formed by fixing two plate-like bodies on the outer peripheral surface of the roll. To do.

The bran box 10 is arranged below the screw roll 12.

A space for storing paddy or brown rice is formed at the bottom of the hopper 30 at the front position of the whitening roll 12c, and pressure is applied to the paddy and brown rice accumulated in this space from above by a compression plate 40. Simultaneously, the paddy or brown rice is pressure-fed by the whitening roll 12c, and the paddy or brown rice is rubbed with pressure to polish.

Since the paddy or brown rice is continuously pumped forward, the paddy or brown rice moves around the bottom of the hopper 30 and is circulated again so as to enter the rice polishing section from the outlet 32 again to be whitened.

In addition, when whitening rice or brown rice, the pressure is applied as described above to whiten the rice, and thus the temperature of the rice rises due to friction during whitening. Since this rise in rice temperature deteriorates the taste of polished rice, it is necessary to polish the rice with as little temperature as possible. Therefore, the rice mill of this embodiment is provided with a cooling mechanism.

Reference numeral 42 denotes a bellows that opens to the side wall of the introduction path 34 and extends from the side wall. A suction fan 44 is provided at the end of the bellows 42.
Is installed. A motor 45 drives the fan 44.
An air guide tube 46 extends downward from the side exhaust side of the fan 44,
The lower end of the air guide pipe 46 opens laterally of the bran removal net 16 as a blower opening.

FIG. 4 shows the arrangement of the air guide tubes 46. The air guide tube 46 is opened so as to blow air toward the outer peripheral surface of the bran removal net 16.

The bellows 42 and the air guide pipe 46 form an air passage communicating with each other, and by operating the fan 44, the outside air introduction port
The outside air is introduced from 36, and the outside air is blown onto the outer peripheral surface of the bran removal net 16 through the air guide pipe 46. As a result, the paddy or brown rice fed under pressure inside the bran-removing net 16 is cooled. In addition,
Since the airflow is formed in the introduction passage 34 by sucking the outside air, the paddy or brown rice is cooled even when passing through the introduction passage 34.

In this way, the method of introducing the outside air and applying the outside air to the paddy or brown rice is extremely effective in that the rice temperature is not excessively raised, and is effective in improving the taste of polished rice. is there.

Regarding the bran box 10, the rice or brown rice dropped from the introduction path 34 onto the screw roll 12 is pumped forward on the bran removal net 16 with the rotation of the screw roll 12, and the rotation of the polishing blade 12b. The rice husks and bran are peeled off by, for example, fall into the bran box 10 from the mesh of the bran removal mesh 16, but since the bran box 10 is completely closed by the cover portion including the cover 18, the bran or the rice bran Can be completely prevented from scattering outside the bran box.

The filter 20 provided on the cover 18 acts as an air vent, and the outside air, which is the cooling air blown out from the air guide tube 46, is exhausted through the filter 20.

If the outside air is blown to the bran-removing net 16, the rice husk or the bran will be more easily exfoliated. In this case, the rice husks or bran will be scattered further by the air flow,
Since the periphery of the bran removal net 16 is formed as a closed space by the bran box 10, the cover 18 and the cover part having the frame 14 as constituent elements, there is no problem caused by scattering of rice husks and bran.

Further, the rice milling machine of this embodiment can be similarly used when polishing rice from paddy and when polishing brown rice.

Further, the rice milling machine is not limited to the circulation type or the one-pass type.

Although the present invention has been variously described with reference to the preferred embodiments, the present invention is not limited to the embodiments.
It goes without saying that many modifications can be made without departing from the spirit of the invention.

(Effect of the Invention) In the rice milling machine of the present invention, the bran removal net is enclosed in the space closed by the bran box and the cover part, so that the fan blows the cooling air to the outer peripheral surface of the bran removal net. But,
The peeled off rice husks and bran can be surely prevented from falling into the bran box and scattering outside the bran box. Further, the cooling air introduced into the closed space can be exhausted through the filter.

Therefore, the rice to be milled can be suitably cooled by the cooling air blown to the outer peripheral surface of the bran removal mesh, the deterioration of the taste of the milled rice can be prevented, and the peeled rice husks and bran are surely prevented from scattering. Therefore, it is possible to provide a rice polishing machine that is easy to use and is easy to maintain and manage.
