Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] Industrial field of application The present invention relates to a horizontal multi-stage compression device for okara for continuously and efficiently recovering raw material components of tofu contained in okara.

Conventional Technology Conventionally, carbohydrates are contained in the okara produced in the process of manufacturing tofu,
It is used as a feed because it contains protein, fat, etc. However, since Okara has a water content of about 85%, it must be dried due to storage and transportation, but the water content is extremely high. However, it has a drawback that it requires a large amount of its heat energy, cannot cost-effectively counter imported feed, and cannot be reused as a raw material for tofu by directly drying it.

The problem to be solved by the present invention is to efficiently recover the tofu raw material contained in okara and reuse it to reduce the cost, reduce the thermal energy required for drying in the next step, and reduce the cost of the conveyor belt. It is intended to provide a horizontal multistage compression device for Okara that enables long-term use.

A roller 24 is arranged above the terminal side of the above so that a certain amount of Okara W is continuously fed onto the conveyor belt 2.

Next, since the compression mechanisms 6, 6a ... Have the same structure, only the compression mechanism 6 disposed on the most upstream side will be described. Such a compression mechanism 6 contacts the back side of the conveyance path of the conveyance belt 2. , The base 26 is fixed between the columns 25, 25a ... Standing on the frame 3, and a hard lower roller 28 made of metal or the like is rotatably mounted on the bearing 27 fixed to the base 26. A pillar 25 above the coaxial conveyor belt 2,

Next, the operation of the horizontal multi-stage compression device for Okara according to the present invention will be described. When the drums 4 and 4a are rotationally driven by the rotation of the drive motor 38 through the chain belt 39, the conveyor 2 circulates in the direction of the arrow in the figure. And the other compression mechanism 6, 6a ...
The lining roller 33 of is driven to rotate in the direction of the arrow in the figure,
The belt conveyor 21 and the roller 24 of the Okara feeding device 5 are driven to sequentially load and place the material from the discharge port 23 of the hopper 19 on the transport conveyor 2 and transfer it downstream.

Then, during the transfer to the downstream, the compression mechanism 6,
The water contained in the okara W is squeezed out by the compression action of the lower roller 28 and the lining roller 33 of 6a ... at the compression portion P and is collected in the liquid collecting tank 40.

Further, in the above-mentioned compressed state, the gap Y between the compression mechanisms 6, 6a ... is gradually reduced to enhance the compression action, and as shown in FIGS. 3 and 4, the lining roller 33 at the compression portion P is formed. By reducing the flat width Z of the elastic member 32, the biting of the Okara W is improved.

Further, when the guide portion 35 provided in front of the compressed portion P is used as the guide roller 35, since the conveyor belt 2 is displaced upward by the guide roller 35, the stagnation of the Okara W at such a portion is reduced and the guide roller 35 is smoothly moved. When the guide part 34 can be supplied to the compression part P, and when the guide part 34 is used as the guide plate material 36, the conveyor belt 2 is supported up to immediately before the compression part P to prevent the sinking downward, and the gap X is sequentially provided to the compression part P. Okara W in front of the compression part P because it is small
It is possible to supply the compressed portion P smoothly by reducing the stagnation.

Further, the variation of the compression friction resistance at the compression portion P when the Okara W is not uniformly applied onto the transportation belt 2 and the variation of the partial frictional resistance between the drum bodies 4 and 4a and the transportation belt 2 cause the transportation belt 2 to move. Regarding the lateral displacement, the press belts 13 and 13a of the lateral displacement prevention devices 10 and 10a constantly press the conveyor belt 2 suspended on the drum bodies 4 and 4a to regulate the displacement. .

In addition, when the displacement of the conveyor belt 2 occurs, the displacement of the conveyor belt 2 is detected by the sensors 18 and 18a, and the swing angle of the correction rollers 17 and 17a is controlled to determine the displacement direction. The side edge of the conveyor belt 2 is pressed in the opposite direction from diagonally above to correct the positional deviation.

Further, when the straightening rollers 17 and 17a are fixedly arranged, the side edge of the transport belt 2 comes into contact with the straightening rollers 17 and 17a due to the positional deviation of the transport belt 2, so that the side edge of the transport belt 2 is The portion is pressed obliquely from above and corrects by acting so as to return the conveyor belt 2 in the direction opposite to the position shift direction.

Further, since the conveyor belt 2 is made of cloth, the compressed okara W is discharged to the next drying step without adhering.

[Effect of device]

In short, the present invention is an endless conveyor belt 2 made of cloth.
And a lower roller 28 that comes into contact with the rear surface side of the conveying path of the conveying belt 2, and a lining in which an elastic member 32 is attached to the outer periphery above the conveying belt 2 coaxial with the lower roller 28. A gap Y is provided between the roller 33 and the conveyor belt 2, and the diameter of the lining roller 33 is set to the lower roller.
Since the compression mechanisms 6, 6a having a larger diameter than the diameter of 28 are provided, the flat width Z of the elastic member 32 can be made small due to the difference in diameter between the lining roller 33 and the lower roller 28. Thereby, even if the pressing force is the same, the pressing force per unit area is increased, and the biting property of the Okara W placed on the conveyor belt 2 is improved, and the moisture containing the tofu raw material contained in the Okara W is improved. Since the tofu raw material contained in Okara W can be reused and the cost can be reduced because it can be efficiently compressed and recovered, and since the water is dehydrated, the heat required for drying in the next step is required. Energy can be reduced.

Further, since the conveyor belt 2 is made of cloth, it does not adhere to the conveyor belt 2 even during compression and has a good releasability of the Okara W, so that it can be smoothly transferred to the next process without providing a separating device or the like. You can

Further, since the guide portion 34 for displacing the conveyor belt 2 slightly upward is disposed in front of the compression portion P between the lining roller 33 and the lower roller 28, the stagnation of the Okara W at such a portion is reduced and the compression portion is smoothly compressed. When the guide portion 34 is the guide plate member 36, the conveyor belt 2 is supported up to immediately before the compression portion P so as to regulate the sinking downward, and the gap X is gradually reduced to the compression portion P. Therefore, the stagnation of the okara W in front of the compression part P can be further reduced and the okara W can be smoothly supplied to the compression part P, so that the compression failure at the compression part P can be eliminated and the compression efficiency can be improved.

Further, since the straightening rollers 17 and 17a that come into contact with both side edges of the return path of the conveyor belt 2 are provided, variations in the compression friction resistance at the compression portion P when the Okara W is not evenly applied on the conveyor belt 2 and For the positional deviation of the conveyor belt 2 due to the partial variation in the frictional resistance between the drum bodies 4 and 4a and the conveyor belt 2, the conveyor belts 2 are corrected by the correction rollers 17 and 17a.
By pressing the side edge of the conveyor belt obliquely from above and correcting it by returning the conveyor belt 2 in the direction opposite to the misalignment direction, an overload (twist or wrinkle) applied while the conveyor belt 2 is circulated. It is possible to extend the life of the conveyor belt 2 and to use the conveyor belt 2 for a long period of time, which is a great practical effect.
