Moreover, since the adhesion of the powder in the processing equipment is gradually accumulated every time the operation is continued, if the powder adheres for a long period of time, for example, the powder that is the raw material of the food product will be corroded or the chemical raw material If it is a powder, its components may deteriorate and become foreign matter, which may adhere and remain on the ceiling of the processing equipment. The foreign matter remaining in the processing machine may fall into and mix with normal powder being processed. When such a situation occurs, there may occur serious troubles such as deterioration of quality of various powders being processed and, in the worst case, loss of commercial value. Therefore,
Generally, the operation of various powder processing equipment is stopped periodically and the ceiling part of the processing equipment to which the powder adheres is blown off by an operator with an air gun or washed with high-pressure jet water. . In addition, with these various types of powder and granular material processing equipment, the treated powder and particulate materials tend to rise in the processing chamber or flow back into the powder supply system. A suction duct (negative pressure suction duct) for applying a negative pressure to form a smooth flow of air is provided outside the housing.

ーサイドからの改良の要望が指摘されていた。However, there are the following drawbacks when cleaning the apparatus for treating various powders by this conventional method. In the case of a mixer, after stopping the processing operation of the granular material,
Since the worker has to enter the inside of the machine to work, it is dangerous and the worker is also dirty, so it will work in an extremely bad working environment, especially in a mixer for processing food granules, On the other hand, workers may bring in germs into the machine and become unsanitary. When washing the inside of the machine with water, take out all the powder inside, including not only the machine that is going to be washed but also various equipment connected before and after, and perform a washing operation. After the cleaning is completed, the inside of the machine is completely dried before it is put into operation.Therefore, a large amount of work and a long downtime are required from the preparation to the cleaning work before restarting operation. The running cost is high and uneconomical. If the powder adhering to the inside of the machine is washed and washed with water, in places where a large amount of powder adheres, it will absorb the water from the washing and solidify, and the solidified powder will remain inside the machine without being washed away. Sometimes. When a large-scale powder treatment equipment such as a plant is washed with water, a large amount of waste liquid is discharged from the powder treatment equipment after cleaning, so a waste liquid treatment equipment for treating this wastewater is required, and the entire equipment Will result in higher costs. Even in the foreign matter filtering performance of the ceiling-mounted dust collector, whether or not the foreign matter was effectively removed was only inefficient for the running cost. In the conventional treatment equipment for various powders, a suction duct (negative pressure suction duct) is provided to prevent the treated powders from rising in the processing chamber or flowing back to the powder supply system. Negative pressure is sucked from the powder dropping chute, which is located below the processing chamber equipped with a suction duct (negative pressure suction duct), in the ceiling of the granular material processing equipment. To the suction duct (negative pressure suction duct), and sucks up various powder particles that have risen in the powder particle dropping chute or cause a backflow phenomenon to the suction duct (negative pressure suction duct). Therefore, all of the various powder particles sucked and collected from the powder drop chute are not guided to the suction duct (negative pressure suction duct), but are communicated from the powder drop chute to the suction duct (negative pressure suction duct). It may adhere to and remain on the inner wall surface of long pipes, and if such a phenomenon occurs, various powder particles remaining on the inner wall surface of the long pipe will corrode and various bacteria will propagate. . If these germs fall and are mixed with various powders being processed, not only the quality of the various powders being processed is deteriorated, but also hygiene is not preferable. It has been pointed out that the user side has requested improvement of this kind of processing apparatus for various kinds of powder and granules.

提供を目的としている。However, as a result of detailed simulation evaluation of the mixing processing operation of the mixing apparatus for various powders and granules among the above-mentioned conventional apparatuses for processing various powders and granules, it has not been pointed out so far. I came to discover a new problem. This is because the conventional method of newly installing an automatic air cleaning system inside the processing chambers of various powder and particle processing devices does not sufficiently clean the stirring member itself, which is an indispensable structure for various powder and particle mixing devices. To be. Various types of powder and granules to be mixed and processed by this kind of equipment are usually 15
Since it has a water content of from 20 to 20%, it is difficult to obtain a uniform mixed state when mechanically mixing with a stirring member. In order to obtain a uniform mixed state with the conventional stirring member, it is necessary to carry out a mixed operation for a long time with a driving motor having a large torque, so that not only the processing efficiency is bad but also the running is expensive. When trying to mix the liquid with various powders during the mixing process, the conventional method sprays from one point on the ceiling of the mixing process chamber, so the liquid content is not uniform and partially solidifies. There is. Such a problem was not solved. Therefore, the present invention has been made to solve these problems, by improving the stirring member is a structure that is essential as a mixing device for various powders, effective mixing chamber Provide a mixing device for various types of powder particles that realizes excellent cleaning and optimizes the mixing state of various types of powder particles during the mixing process to dramatically improve processing efficiency and economic effects. It is an object.

The high-pressure pulsed air is supplied to the air cleaning nozzle member provided at a predetermined position on the tip of the stirring blade member and at a predetermined position on the outer diameter surface of the rotating shaft of the stirring blade member. As a result, high-pressure pulsed air is discharged into the mixing chamber from the blade tip portion of the stirring blade member and the outer diameter surface of the rotating shaft, and the shock wave generated by this action blows off the powder adhering to the inside of the mixing chamber. And the stirring blade member itself is effectively cleaned. Further, various powder particles being stirred in the mixing chamber are also effectively stirred and mixed to obtain a uniform mixed state. Furthermore, since a buffer layer formed by high-pressure air is formed between the agitating member and the various powder particles in the agitating process in the mixing chamber, the frictional resistance is reduced and the agitating operation can be performed with a small torque. Furthermore, by injecting high-pressure air as a special gas to various powders, it becomes possible to have various gas sterilization, antibacterial, or other functions by the catalytic function of the gas.

As a result, the high-pressure pulse air ejected from the injector nozzle EN provided at the tip of the outer blade F1 and the inner blade F2 of the rotating ribbon screw 1d is spirally ejected into the entire interior of the powder / particle mixing processing chamber 1. Thus, as shown in FIG. 4, a large fluid is formed in the longitudinal direction of the rotary shaft 1c of the ribbon screw 1d. Due to this action, not only the residual powder and granules adhering to the inside of the powder and granular material mixing processing chamber 1 can be cleaned with air very effectively, but also high-pressure air is jetted and mixed during the mixing and processing operation of various powder and granular materials. Normal powders have a moisture content of 15% to 20%,
During the mixing operation, the powder and granules are fluidized and a more uniform mixed state can be obtained. In addition, the fluidization of the powder particles reduces the frictional force of the powder particles hitting the ribbon screw 1d during the stirring operation, so that the torque of the drive motor can be reduced, and the running cost can be greatly increased. It is possible to keep it low and it is possible to dramatically improve durability and reliability. Furthermore, if necessary, the switching valve 12 is switched to the gas accumulator tank 15 to use a catalytic function of a special gas instead of high-pressure air for sterilizing / antibacterial treatment of the powder or granules or changing the powder or granules themselves. It also becomes possible to have a function.

提供を目的としている。However, as a result of detailed simulation evaluation of the mixing processing operation of the mixing apparatus for various powders and granules among the above-mentioned conventional apparatuses for processing various powders and granules, it has not been pointed out so far. I came to discover a new problem. This is because the conventional method of newly installing an automatic air cleaning system inside the processing chambers of various powder and particle processing devices does not sufficiently clean the stirring member itself, which is an indispensable structure for various powder and particle mixing devices. To be. Since various powders and granules to be mixed and processed by this kind of device usually have an optimum moisture content, it is difficult to obtain a uniform mixed state when mechanically mixing with a stirring member. . In order to obtain a uniform mixed state with the conventional stirring member, it is necessary to carry out a mixed operation for a long time with a driving motor having a large torque, so that not only the processing efficiency is bad but also the running is expensive. When trying to mix the liquid with various powders during the mixing process, the conventional method sprays from one point on the ceiling of the mixing process chamber, so the liquid content is not uniform and partially solidifies. There is. Such a problem was not solved. Therefore, the present invention has been made to solve these problems, by improving the stirring member is a structure that is essential as a mixing device for various powders, effective mixing chamber Provide a mixing device for various types of powder particles that realizes excellent cleaning and optimizes the mixing state of various types of powder particles during the mixing process to dramatically improve processing efficiency and economic effects. It is an object.

While rotating the rotary shaft 1c of d, the compressor 14 is operated to supply high-pressure air to the high-pressure air accumulator tank 13 to bring it into a pressurized state, and the sequence controller SC is operated from this state. Then, the sequence controller SC controls opening / closing of the diaphragm solenoid valve 11 according to a sequential program stored in advance in the microcomputer.
