Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a rice hulling device using a rotary senograph, which is designed to be small in size as a whole, and also to reduce the size of the rotary senograph and fill.
f;') can be implemented using one rotating drum.

A rotary separator is a rotary separator in which a large number of pot holes are formed on the inner surface of a rotating horizontal cylinder, and the grains that have been settled in the lower layer are scooped up through the pot holes, and the grains are transferred to a collecting spiral provided at the center ζ'a14 of the rotating horizontal cylinder. Refers to something that can be caught and taken out by a receiving gutter.

One of the deficiencies of conventional hulling equipment that used a rotary separator for grain sorting was that the rotating drum of the rotary separator was equipped with a two-lower, two-stage system that separated the hulled rice from the unhulled rice and the unhulled brown rice. Because the mixed rice cannot be separated sufficiently, the height of the machine is high and the entire device becomes large.

However, rotary Seno (lake-no lj, !j
If a rotary sieve, which is known to those skilled in the art as a gray sieve, is provided in the rotary drum, it is possible to use the rotary sieve for -・Tsuhikoge+l l, and then perform a secondary sorting using the rotary drum, so that the height can be reduced. The purpose of downsizing can be achieved by (t -1/r).

Therefore, the present invention provides a method for handling rice in the hulling room, the wind sorting room, and the grain sorting section (the grain sorting section of the rice-hulling device is replaced by 7Gl of the rotary drum J.
! A rotary separator is equipped with a collection spiral receiving trough with a roughly U-shaped cross section.The rotary separator scoops out the sorted grains through a pot hole formed on the inner surface of the rotary tram and separates the mixed rice of unhulled unhulled rice and unhulled unhulled rice. A sieve tube having a large number of sorting holes formed on the outer periphery is provided in the rotating drum of the rotary separator, and the mixed rice is first sorted by the sieve tube, and then secondarily sorted by the rotary drum. A rice hulling device using a rotary separator, and the width of the sorting holes in the sieve tube are the same as those of the device described above, in which a part of the screening holes is formed into a small hole through which small rice can be separated.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a loading hopper, and 2 denotes a hulling chamber at the top of the loading hopper 1. Of the rice huller A.2, i:H has a pair of left and right huller rolls 3.3.

” Further, a downflow gutter 5 is provided in the wind selection room 4,
A mixed rice receiving gutter 9 for brown rice and unhulled rice and an immature grain receiving gutter 10 are respectively formed at the bottom of the downflow gutter 5, and these qtt combined rice receiving gutter 9 and immature grain receiving gutter 10'' are Install the spiral conveyor 11 and 12 horizontally. 13 is a suction air path, and 14 is a bottom wall. The above structure constitutes the hulling section 15, a case 16 is provided on the side of the hulling section 15, and a grain sorting section 17 is formed inside the case 16. A rotary separator 18 is horizontally installed in the grain sorting section 17 so as to be rotatable. 19 is a rotating drum of the rotary separator 18;
A large number of pot holes 20 are formed on the inner surface of the pot. At the center of the interior of the rotating 1ζ ram 19, a mixed rice recovery spiral receiving trough 21 and a brown rice recovery spiral receiving trough 22, each having a substantially U-shaped cross section, are arranged side by side. A sieve tube 23, which is referred to as a sieve tube by those skilled in the art, is mounted on the upper part of the five-go rice collection spiral receiving trough 21. Sieve tube 235
It is a hexagonal rectangular tube or cylinder, and its sorting hole 25 is formed with a width of 11 to allow brown rice and some unhulled rice to pass through. In addition to the sorting hole 25, there is a sorting hole 2 for sorting small rice as shown in FIG.
It may also form 6. Usually, a sorting hole 26 for sorting small rice is formed on the D1 outlet side 27. Reference numeral 28 denotes a screening hole for separating small sand and bran, and the screening hole 28 is formed on the supply side 30 (FIG. 6). 24 is QrL combined recovery spiral receiver 4igJ2

Next, I will explain the effect.

First, when the raw material paddy is supplied to the loading hopper l, the raw material paddy flows into the hulling chamber 2, and the left and right pair of hulling rolls 3.3
The paddy is crushed between them, falls on the downflow gutter 5, and flows into the winnowing chamber 4. In the wind selection chamber 4, suction air is blown by the action of the suction fan 6, so that the light rice husks are discharged through the discharge pipe 7 from the slide 1''8. The immature grains collide with the bottom wall 14 and flow into the immature grain receiving trough 10, and are transferred to the helical conveyor 12.
is discharged to the outside. The mixed rice of the unhulled brown rice and the unhulled rice that remains after the hulling flows into the mixed rice receiving trough 9, and is transferred to the 11 rice frying grain thrower 3 by the spiral conveyor 11 on the mixed rice receiving trough 9.
6 is supplied to the grain sorting section 17 in the case 16 from the funnel 29.
is fed into the supply side 30 of the j+B space 23. The core is 1
When 23 has the structure shown in Fig. 5, unpolished rice and -l''a1 (unhulled rice fall from the sorting hole 25, and small rice is sieved by the sorting hole 26 at the discharge side 27 of the sieve tube 23, and from the #Jl outlet side 27. Only the unhulled rice falls and flows into the unhulled rice falling gutter 34, and is returned to the loading hopper 1 by the unhulled rice returning thrower 35.The mixed rice of brown rice and unhulled rice that falls from the sorting hole 25 is horizontally conveyed by the spiral conveyor 24. The rice is fed to the end of the rotating drum 19 through the drop port 37 at the end.Since the rotating drum 19 is rotating clockwise in FIG. In the old case, the scooped brown rice is stopped in the brown rice collection spiral receiving trough 22. However, the brown rice stopped in the brown rice recovery spiral receiving trough 22 is dropped into the finished rice flow down trough 32 by the action of the spiral conveyor 31. The finished rice is taken out by the finished rice take-out thrower 33. The 1-nor rice remaining in the rotating drum 19 is returned to the rice receiver bfJ9 and recirculated.

Conventionally, one of the defects of the rotary separator in hulling equipment that uses a rotary separator for grain sorting is that the rotary separator cannot be adequately sorted unless the rotary separator is installed in two lower tiers. One possible reason is that it becomes large.

In other words, one stage (-) of two rotary separators
1, the entire device 1 could be formed at the same size as conventional products without increasing its size, but since the rotary separator is formed in two stages, upper and lower, the entire device becomes extremely large. However, the price was also high and various defects occurred.

However, the present invention has a rice hulling room 2, a winding room 4, a grain selection ya+
