However, in the conventional red pepper grinder, since the powdered red pepper powder is decomposed and filtered to be transported in the powder reservoir, a fine powder is exposed to the outside during the powder transfer step, In the case of red pepper powder, there is a problem that the fine spicy powder is scattered in the workplace and the worker feels pain. The decomposition or decomposition of the pulverized water or the filtration part of the filtration part is not a rotating filter network, There is no apparatus, so that the hole of the filter net is easily clogged and must be communicated from time to time, so that there is an inefficiency inconvenience because the crushing operation must be suspended.

The present invention has been developed to solve the above drawbacks.

The present invention relates to a method for grinding grains or peppers in a separate crusher, crushing the crushed grains or pepper to a particle size of 8 to 12 meshes having an average particle size of 8 to 12 meshes, grinding the crushed material in a container of a predetermined size, (1) for supplying a debris,

A pulverized material transferring unit 3 which is provided at the lower end of the pulverizing unit and receives pulverized and dropped pulverized by the pulverizing roller and transfers it to the outside of the pulverizing unit through a transfer pipe equipped with an electric screw made in the powder receiving unit,

The pulverized material is connected to the feed pipe of the feeder through a connection pipe, and a high speed rotary disintegrator is installed in the rotary filter network in which a low speed rotary pipe is installed at the central portion as a circular pipe and a filter net is attached to the outer periphery thereof. The water is decomposed and the decomposed powder is passed through a 20-40 mesh filter net attached to the outer periphery of a low speed rotary pipe to drop the powder having a particle size of 20-40 mesh into the powder receiving part. The powder is placed on the rotating filter net, The air is injected into the filter net to remove the red pepper powder from the filter net, and is disposed on the side opposite to the inlet line through the filtration net to transfer the unfiltered residue to the return pipe, And the remnant for returning the unreacted remnant to the rupturing material supply section is made up of the transfer pipe 1g And a powder receptacle 7 provided with the filtration unit, is connected to the filtering part decomposition receiving a powder that has passed through the filtering net and the lower portion to the outlet tube (7a) and an air inlet (7b) as the external air flows into the discharge pipe opposite side,

A powder storing portion 10 connected to the powder receiving portion and being connected to the connecting pipe 7h at a top loading port of the powder storing portion so as to suck powder in the powder receiving portion, A first cyclone (8) for separating the air from the flue gas, separating the air from the flue, discharging the air to the exhaust pipe, collecting the flue and dropping the flue to the inlet of the powder storage part, A powder injector 9 for injecting the powder collected by the rotating blades into the powder feeder by making a fan mounting part in the tube to form a rotary blade having six blades and a powder feeder 9 installed under the powder feeder for contact with the powder A dust collector 12 which is connected to the exhaust pipe of the first cyclone 8 through a connection pipe to generate a suction force in the first cyclone, A second cyclone 13 (which is connected to the exhaust pipe 11b of the suction blower) for collecting and collecting a minute amount of powder mixed in the exhaust discharged into the exhaust part 11b of the first cyclone, ) So that grains or red pepper powder can be produced at a particle size of 20 to 40 mesh.

In the present invention as described above, the crushed material having a particle size of 8 to 12 meshes with an average particle diameter of 8 to 12 meshes is crushed into a crushing unit (crushing unit) equipped with a crushing roller (2) and pulverized into particles having a particle size of 20 to 40 mesh. The pulverized powder is introduced into the connection pipe of the decomposition and filtration unit (40) through the transfer pipe of the transfer unit (3) (RPM 50 ~ 70 revolutions) equipped with a rotating filter net (4) equipped with a 20 ~ 40 mesh filter net at the center of the channel and a decomposer (5) rotating at a high speed into the rotating filter net are installed, 4), the crushed powder is transported to the rotating filter net 4 along the connection channel. When the crushed powder is transported into the filtration net 4, the compressed gas collides with the screw blade in the transporting step and is partially decomposed. Contact with stirring wing So that the powder is completely decomposed and disintegrated. The powder passes through the vents of the filter net and is filtered, so that the filtered powder falls to the powder receiving part.

Accordingly, the pulverized powder is filtered and decomposed in the decomposition filtration part to be contained in the powder receiving part, and the remnant that has not passed through the filtration net continues to move along the connection pipe and is introduced into the return pipe 41 formed at the end of the pipe, Is supplied to the inlet port 1c of the crusher feeder 1 along the screw of the feeder pipe 1g, so that the process of entering the crusher feeder again and feeding it back to the crusher is repeated.

On the other hand, since the air injection nozzle for intermittently injecting compressed air of a predetermined pressure is provided at the upper side of the rotary filter net, the powder attached to the filter net is forcibly separated to prevent the holes of the filter net from being clogged, Since the rotating filter network 4 and the powder disintegrator 5 having the same rotation direction are the same, the rotating filter network rotates at a low speed and the powder disintegrator rotates at a high speed, the pulverized material in the rotating filter net is easily decomposed, The filtration action can be quickly achieved.

Thus, the powder contained in the powder receiving portion 7 is sucked into the first cyclone 8 through the connecting pipe 7h connected to the discharge pipe 7a, the air is discharged by the centrifugal action inside the first cyclone, Is charged into the powder storage part 10 by the rotation of the rotary blade 9c of the powder feeder 9 mounted on the lower end connection pipe and is continuously supplied without being sucked into the powder collecting part. At this time, since the flour mixed with the flour is detected and removed by contact with the flour detector 12, the flour does not enter the flour into the flour storage tank, and the exhaust pipe 8b So that the powder in the powder receiving portion can be safely stored in the powder storing portion without being exposed to the outside when the powder in the powder receiving portion is transferred, and clean powder is produced.

The exhaust pipe of the first cyclone 8 is connected to a connecting pipe 11c communicating with the inlet 11a of the suction blower 11 so that the wind blown by the first cyclone is sucked into the suction blower and sucked into the suction blower A small amount of powder mixed in the wind exhausted from the first cyclone 8 is not scattered to the outside but is injected into the dust collecting container 12d of the second cyclone through the outlet 11b, Collect,

This allows the powder contained in the powder receiving portion to be safely stored in the powder storing portion. When powder is stored in the powder storing portion, the dust is drawn out through a discharge pipe 10b having a screw formed laterally at the bottom thereof, So that efficient and hygienic powder production can be achieved.

On the other hand, the flour disintegration section (40) feeds the pulverized powder at a high speed because the flour decomposer (5) having a stirring blade and a feed screw attached thereto is rotated at a high speed rotating shaft at a central portion of the rotating filtration net (4) The filtrate can be passed through the filtration net by the centrifugal force generated in the two stages, so that the pulverized powder can be quickly decomposed while being filtered and accommodated in the powder receiving portion.

In addition, the compressed air injection nozzle installed on the filter network of the decomposition filtration unit intermittently injects the compressed air to drop off the powder adhered to the filter network, thereby preventing the filter network from being blocked, thereby allowing continuous filtration work, The powder is sucked by the suction force acting on the first cyclone and enters the powder storage container. At this time, a fan installation part is formed in the connection pipe formed at the inlet of the powder storage container, and a rotary blade having six blades is installed therein, So that the powder that has been sucked into the storage tank can be quickly introduced into the storage tank without being affected by the external suction force because the rotating blade is rotated in one direction by closing the connection pipe. A flour detector that rotates with a magnet rod on the lower side of the rotating blade Which effectively absorbs the flour mixed with the falling flour, thereby preventing the flour from being mixed with the flour.

The rotating filter network of the present invention is made of stainless steel and is coated on the outer surface of the rotating tube and fixed on the gold mango tongue so that it can be easily attached and detached and the gold mango tongue is coated on both sides of the outer surface of the rotating tube, (B) and the nut (N) interposed between the inner side through holes of the fixing member in a state where the bolt end of the fixing member of one side is in contact with the inner side surface of the outer side of the fixing member, So that the end of the filter net interposed between the rotary pipe and the gold mango tongue is fixed to the surface of the rotary pipe in close contact with each other. Thus, a secure and firm filter network can be formed without leakage of dust due to no gap in the fixing portion of the filter net. There is an advantage in that it is easy to separate when the nut (N) is merely removed when exchanging, so that it is advantageous to exchange the filter net, (7b) and (4g ') in which external air is introduced into the case of the disassembling and filtration unit are formed. Therefore, the suction force acting in the suction conveying step of the pulverized material and the received powder smoothly acts, And a feed water level sensor S1 for detecting the supply amount of the crushed material on the crushing roller of the crushing unit so that the crushed material supplied to the crushing roller is prevented from being continuously supplied and accumulated before being crushed between the crushing rollers So that the crushed material can be prevented from being clogged at the supply part, and the continuous powder production can be automated.
