Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a powder uniform dispersion device for uniformly dispersing powder and granular materials such as salt and seasonings.

(Prior art and its problems) For example, when making rice balls, it is best to sprinkle salt on the cooked rice and then stir it so that the salt adheres to the surface of the rice grains. ing. However, in places such as school lunch factories where rice is continuously cooked in large quantities, it is difficult to evenly disperse salt into the continuously cooked rice by hand, so water is added to the rice before cooking. Rice was cooked with salt added to it in a rice cooker, or salt water was sprinkled on the cooked rice and then stirred.

Both of these methods allow salt to be added uniformly to the rice, but the former has the problem of leaving a core in the cooked rice, and the latter leaves the rice sticky, resulting in an inferior taste. It was hot.

(Purpose of the invention) In view of the above-mentioned conventional problems, the present invention provides a powder uniform dispersion device capable of uniformly dispersing and supplying salt to, for example, continuously cooked rice in large quantities. With the goal.

(Means for Solving the Problems) In order to solve the above-mentioned conventional problems, the present invention has a cylindrical body 4 having a powder discharge port 5 formed over its entire length on the lower surface and arranged in a horizontal state. The powder supply port 17 of the powder supply device 8 is connected to the center of the upper surface of the cylindrical body 4, and the fan 20 is connected to the center of the side surface of the cylindrical body 4.
A rotary shaft 24 rotated by the prime mover 23 is concentrically arranged in the cylindrical body 4, and a predetermined interval is provided between the center of the rotary shaft 24 and from the center to both ends thereof. At the same time, a large number of blades R ₁ to R ₉ and L ₁ to _{L 9} are arranged for transporting the powder and granular material 25 toward both ends of the rotating shaft 24, and
A configuration is adopted in which the propulsion angle θ of each of the blades R ₁ to _{R 9} and L ₁ to _{L 9} is appropriately displaced toward both ends of the rotating shaft 24.

(Function) In the above configuration, the rotary shaft 2 is
4 is rotated and the powder 25 is supplied to the center of the cylindrical body 4 by the powder supply device 8 and air is blown by the fan 20.
is distributed to the left and right by each of the blades R ₁ to _{R 9} and L ₁ to _{L 9} of the rotating shaft 24, and is conveyed toward both ends of the rotating shaft 24 on an air flow. During the conveyance, the powder 25 gradually loses its flow velocity and falls, and is dispersed and discharged almost uniformly over the entire length of the cylinder 4 from the powder discharge port 5 of the cylinder 4.

In FIG. 1, reference numeral 29 denotes a rice stirring blade disposed above the belt conveyor 2 on the downstream side of the shutter 21.

The operation of the above configuration will be explained. First Hopper 10
When salt 25 is put into the hopper 10 and the electromagnetic device 16 is activated, the trough 11 is vibrated and the hopper 10
The salt 25 inside is sent out in appropriate amounts. The delivered salt 25 falls from the salt supply port 17 and enters the cylindrical body 4, and most of it is distributed to the left and right by vanes R ₁ and L ₁ rotated by the motor 23. Then, only a small amount of the salt 25 that has passed through the gap 27 between the fan-shaped plates 26 forming the blades R ₁ and L ₁ falls as it is and is discharged from the salt discharge port 5 . Next, the salt distributed to the left and right is delivered to each blade R ₂ → R ₃ ... → R ₈ , L ₂ → L ₃ ... L ₈ in order, and during that time, each blade R ₂ to _{R 8} , L ₂
~ Salt 2 that passed through the gap 27 of L ₈ and lost its flow velocity
5 falls and is discharged from the salt outlet 5. Since the blades R ₉ and L ₉ at both ends are attached in opposite directions, the salt 25 is knocked off. As described above, the salt 25 is almost uniformly dispersed over the entire length of the cylindrical body 4, slides on the shooter 21, and is sprinkled onto the rice 1 on the belt conveyor 2. The rice 1 with the salt 25 evenly distributed is the rice stirring blade 2.
9, the salt 25 is evenly attached to the surface of the rice grains.

In the above configuration, the blade R ₁ by the motor 23
- The rotational speed of _R9 , _L1 to _L9 , the amount of air supplied by the fan 20, the propulsion angle θ of each blade _R1 to _R9 , _L1 to _L9 , and the number of fan-shaped plates 26 are set appropriately. Therefore, depending on the length of the cylindrical body 4, the salt 25 can be uniformly dispersed over its entire length.

In the above embodiments, the case where salt is uniformly dispersed has been explained as an example, but it can also be used for sprinkling seasonings evenly on foods, and it can also be used for applications other than foods, such as for example in manufacturing. It can also be used in industry to uniformly sprinkle granules onto raw materials.

(Effects of the invention) As described above, according to the powder uniform dispersion device of the present invention, the powder and granules supplied to the center of the cylinder are distributed to the left and right, and are carried by the air flow to both ends of the rotating shaft. During this time, the water gradually loses its flow velocity and is dispersed and discharged almost uniformly over the entire length of the cylindrical body, making it possible, for example, to uniformly sprinkle salt onto rice that is continuously cooked in large quantities. Yes, you can get delicious food.
