As shown in FIG. 2, in addition to the above-described gear motor 23, a buckwheat flour collection box 87 and a foreign matter collection box 88 are arranged side by side in the lower part of the housing 20.
The buckwheat flour collection box 87 has an elliptical hole 69 of the flour collection member 68.
From the dust collection path 89 to collect foreign matter
8 is connected through an elliptical hole 64 formed in the powder sieve member 60, a trough 67, and a dust collecting path 65.

Next, the process of milling buckwheat granules using the mill having the above-mentioned structure will be described. First, the buckwheat grains that have been put into the raw material hopper 21 are supplied by a predetermined amount into the raw material supply pipe 34 while the grain amount is adjusted by the supply amount adjusting shutter 27, and the lower opening 41 of the vertical pipe 37 is closed by the opening / closing valve 42. It accumulates in the scrapped raw material supply pipe 34. When the bush 45 provided at the upper end of the vertical pipe 37 reaches the position of the opening / closing dog 47 as the upper mill 22a rotates, it rides on the pressing surface 48 and pushes down the rod 40, and the opening / closing valve 42 descends to move vertically. The lower opening 41 of the pipe 37 opens and the buckwheat grains 33 accumulated in the raw material supply pipe 34 fall. The buckwheat grains 33 that have fallen through the vertical holes 38 of the upper mill 22a are
It falls on the contact surface 51 with b and is crushed between the rotating upper mill 22a.

The crushed buckwheat flour is gradually sent out on the circumference and drops from the circumferential line 52 of the contact surface 51 onto the powder receiving member 53. The buckwheat flour falls over the entire circumference of the powder receiving member 53 and is scraped by the brush tool 70 which moves together with the rotation of the upper mill 22a. The scraped buckwheat flour falls from the opening 54 of the powder receiving member 53 onto the powder sieving member 60, but in that case, the dropping position of the buckwheat flour shifts along the notch 57 of the opening 54 in the front-back direction. In addition to this, the falling position of the buckwheat flour shifts to the left and right due to the outward inclination of the powder receiving guide plate 55 disposed below it, so that the buckwheat flour solidifies in one place and falls in a dumpling shape. Without falling, it falls in the state of being dispersed in the front, back, left and right.

The buckwheat flour that has fallen from the opening 54 onto the powder sieve member 60 is moved by the brush 71 immediately after it falls,
It is rubbed on the net 62 and sieved from the mesh. Most of the buckwheat flour is sifted from the mesh 62 while the brush 71 moves around the powder sieving member 60 about one round. Contaminants such as cuticles and dust that do not pass through the net 62 are carried by the brush 71 to the elliptical hole 64, and then guided to the dust collection path 65 and collected in the contaminant collection box 88 as they are. Unlike the conventional method in which the buckwheat flour is shaken off by horizontal vibration, the buckwheat flour is forcibly rubbed against the mesh 62 and is sieved off.
The buckwheat flour will not bead up or harden on the top.

The buckwheat flour that has been sieved from the powder sieving member 60 onto the powder collecting member 68 moves on the brush tool 72.
Scraped by. In this case, since the brush 72 is attached to the front of the brush 71 of the powder sieving member 60 with respect to the rotating direction of the upper die 22a, the brush 72 was slid onto the powder collecting member 68 by the previous rotation. The buckwheat flour will be scraped, and the buckwheat flour will be dropped into the elliptical hole 69 before the next scraping.

The buckwheat flour collected in the collection box 87 from the elliptical hole 69 of the powder collection member 68 through the powder collection path 89 can be collected by periodically pulling out the collection box 87 from the housing 20, but It is possible to collect smooth buckwheat flour with finer particles compared to the case of using the milling device of No. 1, and the yield of buckwheat flour is 95 to 98% compared to the conventional 80 to 85%.
Can be up to the rank.

In the above embodiment, the case where buckwheat grains are used as grain grains has been described, but it goes without saying that it can be applied to grains other than buckwheat.

[0042]

As described above, according to the grain-graining apparatus of the present invention, the grain powder crushed by the stone mortar is once received on the powder receiving member, and the powder is scraped and collected before the powder sieving member. Since it was dropped onto the net and rubbed against a net with a dusting tool such as a brush, it became difficult for beads and lumps of grain powder to form on the powder sieving member, resulting in better sieving efficiency and Yield improves. In addition, since it is difficult for beads and lumps of grain flour to form, it is possible to reduce the grain size and mesh size during crushing, and grain grain with fine particles can be obtained accordingly.
A smooth product with good texture can be produced.

According to the grain milling apparatus of the present invention,
In addition to the above effects, a feed amount adjusting shutter for feeding a predetermined amount of grain grains is provided at the feed port of the raw material hopper, while an open / close valve is provided in the raw material supply pipe and the opening / closing operation of the open / close valve is performed by rotating a millstone. Since it is interlocked with, it is possible to always keep the supply amount of the grain grains sent from the raw material hopper to the stone mill constant, and to easily adjust the supply amount, though it is a simple means.
