DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice hulling adjusting machine integrally provided with a centrifugal dewatering type hulling means and a rotating rice selection means, which is particularly suitable for in-house treatment of farmers and the like.

[0002]

2. Description of the Related Art In the operation of adjusting rice hulls for shipping brown rice, a process of removing rice hulls to produce brown rice and sorting waste rice from the brown rice is combined. Conventionally, those processes are generally performed using each independent rice huller and rice sorter. However, small-scale and micro-scale farmers do not have machines with small throughput according to scale, and machines with large throughput are expensive and unprofitable. The fact is that it is outsourced.

[0003] On the other hand, in recent years, the number of farmers who store their own rice in paddy storage without deterioration in taste during storage has increased, and this tendency is the same regardless of the size of the rice. This tendency is particularly strong for small-scale farmers who outsource paddy-grinding work. In order to obtain milled rice from the rice stored as their own rice, even large-scale farmers who are permanently equipped with a rice hulling machine and rice sorting machine, because large machines are wasteful and operation is troublesome, After once turning into brown rice with an easy-to-operate small rice crusher, the rice is milled with a hand-held rice mill, or a built-in milling device and milling device, for example, Japanese Utility Model Publication No. 61-10755, Japanese Patent Publication No. 63-20175 U.S. Pat.

[0004]

To ship brown rice,
If the rice is removed with a rice hulling machine, the quality is poor due to the large amount of waste rice mixed in.
For small-scale farmers with small shipments, as described above, the combination of conventional rice hulling and rice selection machines not only takes up space, but also is costly and unprofitable. There is a problem that it takes time and effort.

[0005] Further, in order to whiten the stored own-owned paddy, a rice milling machine disclosed in the above-mentioned gazette or a small-sized centrifugal milling rice mill is used to make brown rice. It has been practiced to use other rice milling machines, but in any of these methods, brown rice without removing waste rice is removed, so the taste of rice is reduced, There is a problem that rice milling is liable to cause rice jams. In addition, if the brown rice after the rice hulling is sorted by a rice sorting machine separately,
Although it is possible to remove waste rice, the operation is very troublesome.

As disclosed in Japanese Unexamined Utility Model Publication No. 1-92241, there is known a rice milling machine which incorporates a rice selection machine for removing scrap rice from brown rice after the milling. This is because after removing the unpolished rice, the milled rice is removed by the built-in rice selection machine and then polished, the taste of polished rice does not decrease,
Since the brown rice after passing through the rice selection machine cannot be separately taken out of the machine, it is unsuitable for work for shipping brown rice.

The present invention has been made in view of such a conventional problem, and a centrifugal dehulling rice huller and a rotary drum type grain sorter are integrally combined to form a compact. , So that it is possible to sort out waste rice removal at the same time as rice hulling work. The aim is to provide an inexpensive paddy rice adjusting machine.

[0008]

SUMMARY OF THE INVENTION The present invention relates to a centrifugal dewatering device for dehulling rice, a rice husk sorting device for separating dehulled brown rice and rice husk, and a powder removal method for brown rice.籾 Equipped with a paddy sorter for removing rice, a thrower for frying the sorted brown rice, and a rotary drum type rice sorter for sorting and removing waste rice in brown rice. The first feature is that the sized rice discharge port is set high and is mounted on the further upper portion of the sorting apparatus. In addition, in the rice sorting machine, the outlet from which the sized brown rice is discharged is provided at a position slightly lower than or higher than the upper end of the paddy hopper into which the paddy to be supplied to the dewatering device is put. This is the second characteristic.
