The present invention is a grinding method for coarsely pulverizing various agricultural products such as barley, soybeans, wheat, pepper, etc. in three-dimensional form or finely pulverizing in powder form; A pulverizing apparatus comprising: a pair of pulverizing rollers installed in a cylindrical rotating drum having a feed-screw formed on an inner wall thereof, so that the pulverized material introduced into the rotating drum is gradually moved toward the discharge port, and then from coarse grinding to fine grinding. It is intended to provide a method and apparatus for crushing agricultural products so that the grinding operation can be performed by a single continuous process up to a large amount of agricultural products within a short time.

Conventionally, in crushing agricultural products, a pair of crushing rollers, which are generally rotated, are installed in an exposed state, and the crushed powder is passed through the pulverized material through a pair of rotating crushing rollers. Since once passing through the grinding roller, it is impossible to accomplish the desired grinding operation due to the function of the grinding machine. Therefore, four to five grinders having different grinding granularities are installed, and the powder is repeatedly supplied several times. It was to be.

That is, since the worker has to carry out the grinding work by directly moving the grind material from the coarse grinding machine to the fine grinding machine, the work efficiency is reduced, and the noise is greatly generated because the grinding work has to be performed while the grinding roller is exposed to the outside. When the pulverized powder pulverized in the powder state is moved from the first crusher to the second crusher, it is scattered to the work place, polluting the surrounding environment with the loss of raw materials, and the worker inhales the scattered powder for hygiene. There was a problem.

The present invention is to provide a pair of grinding rollers in the rotating drum to solve the above problems, and to supply the powder to be repeatedly fed between the grinding rollers while the material to be transported in the rotating drum, the grinding object is ground Hygienic and efficient by allowing the grinding process to proceed gradually from coarse to fine grinding in the process of repeatedly passing through the roller, thereby completing the whole process from coarse to fine grinding in one rotating drum As described below, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

(Example)

Shown in the drawings is a configuration of a pulverizing apparatus for carrying out the present invention, and when the pulverized material 12 injected into the hopper 9 is fed into the rotary drum 1 from the feed inlet 5, it is collected. The pulverized material 12 dropped on the pair of grinding rollers 2 installed in the center of the rotary drum 1 through the cylinder 10 is pulverized while passing through the grinding roller 2 and then bottom surface of the rotary drum 1 It will fall to the negative to complete the primary grinding process.

After the primary grinding process, the pulverized product dropped on the inner bottom surface of the rotating drum 1 is pumped up the pulverized object 12 by the feed screw 3 formed on the inner circumferential surface of the rotating drum 1, and the feed screw ( With the rotation of 3), the crushed material 12 is dropped into the collecting container 10 at the position where the bagets plate 4 is rotated to the upper part of the collecting container 10, thereby performing secondary grinding as in the above-mentioned primary grinding process. The process is going on.

Therefore, each time one baget plate 4 is rotated 180 degrees, the pulverized object 12 falls into the collection container 10 at the position advanced by 1/2 pitch of the feed screw 3, and is again crushed. That is, this is, the grinding object 12 is repeated as many times as the feed screw (3) corresponding to the number of pitches 2 passes through the grinding roller (2), the grinding process proceeds, Water 12 is pulverized again as it progresses by 1/2 pitch as described above from the rear end of the grinding roller 2 toward the front end, and then gradually pulverized from the coarse grinding state to the fine grinding state, and then the outlet 6 is opened. It will be automatically discharged through to complete the grinding process.

The specific method and apparatus of the above-mentioned grinding | pulverization process are demonstrated.

The rotating drum 1 is divided into two parts, the upper and lower parts of the rotating drum 1, and the upper drum 1a and the lower cylinder 1b are assembled to each other. The one side wall of the rotating drum 1 cuts off the center surface of the hopper. The apparatus space part 11 is formed so that the feed-in port 5 connected to (9) may be inserted, and the outlet port 6 in which two opening and closing pipes 13 and 13 'are installed by a hinge is formed near the lower end of the other side wall. On the outer circumferential surface of the rotating drum (1), a tire ring (tire-ring) 14 is fitted to both left and right sides so as to be supported and rotated by the driving roller 8.

In addition, a feed screw 3 is formed on the inner circumferential wall of the rotating drum 1, and several screw plates 4 are formed in the feed screw 3 at every pitch. In the inner space of the rotating drum (1), a pair of grinding rollers (2) were installed in parallel with the rotating shaft of the rotating drum (1), and the upper and lower collecting cylinders (10) were installed above the grinding roller (2). On the lower side of the grinding roller 2, a pair of rotary brushes 7 were installed so as to be rotated to enter into the grinding roller 2.

Particularly, the grinding roller 2 forms grinding blades 2a, 2b, and 2c which are different from each other so that the grinding grains gradually become finer from the feed inlet 5 side toward the outlet 6 side as necessary. It can be configured to be selectively used according to the type of agricultural products by installing the.

In pulverizing the agricultural product by the pulverizing device of the present invention configured as described above, when the pulverized material 12 is supplied into the hopper 9 provided outside the upper side of the rotating drum 1, the pulverized material is transferred through the feed inlet 5. After falling into the collecting container 10, 12 is pulverized primarily while passing through the grinding roller 2, and falls to the inner bottom of the rotating drum 1. As shown in FIG. At this time, the rotating drum 1 is that the one side wall is formed by the device space portion 11 to continue the rotation without interruption of the feed inlet (5), which is accumulated on the inner bottom surface of the rotating drum (1) After the first grinding process, the pulverized object 12 advances the bottom surface of the rotating drum 1 in accordance with the rotation of the feed screw 3, and is formed by the base plate 4 formed at each pitch of the feed screw 3. When the baguette plate 4 is rotated and reaches the upper part of the collecting container 1 while being pumped up, the pulverized material 12 accumulated on the baget plate 4 falls into the collecting container 10 and is again crushed by a roller. Through 2) the grinding operation is repeated.

Therefore, each time the baget plate 4 is rotated 180 ° from the lower side to the upper side, the pulverized object 12 is pulverized in the position moved to the discharge port 6 side by 1/2 the pitch length of the feed screw 2. Since it is to fall down to the regrind action, the pulverized material 12 is repeated a dozen times between the transfer inlet (5) to the discharge port (6), the baguette plate (4) You can also adjust the number of repetitions of grinding as the number of installation of.

Then, the grinding blades (2a) (2b) (2c) of the grinding roller (2) installed in the rotating drum (1) is formed to be differently pulverized so as to gradually finely pulverized toward the discharge port (6) toward the feed inlet (5) side It can be selectively used according to the type of agricultural products by grinding, by grinding off the pulverized matter attached to the surface of the grinding roller (2) by a brush (7) installed on the lower side of the grinding roller (2) In order to maintain the clean state at all times to improve the grinding efficiency, the rotating drum (1) is to be separated up and down to facilitate internal cleaning, as well as two opening and closing plates (13) in the outlet (6) 13 'is installed so that the pulverized powder is prevented from scattering outside the rotating drum 1 while the outlet 6 is opened only downward.

As described above, the present invention is capable of automatically and consistently performing a pulverization operation by one crushing apparatus without installing a plurality of pulverizers having different crushing granularities, and in particular, rotating the crushing roller 2 with a rotating drum 1. By installing inside to reduce the generation of noise, to prevent the processing of the pulverized material 12 to be scattered to the outside is to exhibit a hygienic, efficient grinding action.
