Description

[Detailed description of the invention] "Industrial Application Field" This invention relates to a continuous bean paste sedimentation device used in the production of raw bean paste.

``Conventional technology'' The bean soup made by boiling and grinding beans has bean paste particles of 60 to 100.
The mixture was sieved into a sieve (9 parts water, 1 part bean paste) and placed alternately in a plurality of batch-type sedimentation tanks (27 m ³ ) to perform sedimentation separation. That is, the supernatant water is drained through an overflow pipe that can be adjusted up and down, and the sediment is discharged from the outlet provided at the bottom to form a thick bean paste, which is then dehydrated with a vacuum filter to produce raw bean paste products. That's what I got. However, in the above-mentioned batch type sedimentation tank, if the bean paste is supplied during sedimentation, the supernatant water and the sedimented bean juice are agitated and separation becomes difficult, so continuous sedimentation cannot be performed. Therefore, a large number (9) of batch-type sedimentation tanks were placed on the floor, and the empty first
While the bean paste is being supplied to the tank, it is necessary to sequentially remove the precipitated bean juice from the 9th tank from the outlet, which requires a large space and requires manual labor to adjust the level of the overflow pipe. It was hot.

``Problems to be solved by the invention'' This invention is capable of continuously supplying bean paste and continuously discharging precipitated bean juice and supernatant water, and which does not take up much space and does not require human power to operate. The purpose is to obtain a precipitation device.

``Means to solve the problem'' This proposal is to install a sedimentation tank with a funnel-shaped lower part in the machine frame, provide an outlet at the lower end of the tank, and provide an overflow weir at the upper end of the tank. A downward supply pipe for bean paste is arranged at the top so that its lower end outlet is located below the water surface below the overflow weir, and its center is located directly below the lower end outlet of the supply pipe. An outflow bean soup baffle plate is provided, and a short upright cylinder is arranged on the outer periphery of the baffle plate at a distance t, the lower end opening of the short cylinder is placed in the middle of the sedimentation tank, and the bean juice is directed downward. It is constituted by a continuous bean paste sedimentation device in which a supply pipe and the above-mentioned short upright tube are supported concentrically.

"Function" Therefore, when the bean paste is made to flow out from the lower end outlet 7 of the downward supply pipe 6, the outflowing bean paste is prevented from being discharged downward by the baffle plate 8 immediately below, and the discharge direction is is oriented horizontally, but it collides with the inner surface of the upright short tube 9 and is guided to the inner surface of the short tube 9 through the gap t without mixing with the supernatant water 21 already stored outside of the short tube 9. It flows down into the lower end opening 10 of. During this period, the descending bean paste flows down through the short tube 9, which has an inner diameter much larger than the inner diameter of the lower end outlet 7 of the supply pipe 6, and below the baffle plate 8. The flow rate of the bean paste decreases, the flow becomes rectified, and the bean paste is slowly supplied from the lower end opening 10 to the middle of the settling tank 3 without disturbing the already stored bean paste. The water that settles in the lower part 2 becomes supernatant water 21 and is discharged to the outside of the tank 3 from the overflow weir 5 at the upper end. That is, the supplied bean soup flowing out from the lower end opening 10 is continuously supplied without affecting the sedimentation and separation phenomenon of the stored bean paste. In addition, as the sedimented bean paste goes downward, the cross-sectional area of the funnel-shaped part 2 gradually decreases, so the interval between the descending bean paste particles also gradually decreases, and the concentration of the sedimented bean soup gradually increases. is discharged.

"Example" The upper part of the bean paste settling tank 3 is supported on the machine frame 1, and the tank 3
The lower part 2 is formed into a funnel shape, and a discharge port 4 is provided at the lower end, and a three-way opening/closing valve 11 is provided in the discharge port 4. A zigzag-shaped overflow weir 5 is provided on the upper edge of the tank 3, but the upper edge itself may be used as the overflow weir 5. On the outside of this overflow weir 5, an outer cylinder 12 is provided on the outer peripheral wall of the tank 3, and the lower end of the outer cylinder 12 and the tank 3 are connected with a bottom plate 13 to form an overflow supernatant water discharge gutter 14.
A discharge pipe 15 is connected to this. A downward supply pipe 6 for bean paste is arranged above the center line of the sedimentation tank 3 along the same center line, and a lower end outlet 7 is opened at the lower level of the overflow weir 5. This supply pipe 6 has an inner diameter of about 75 to 100 mm, and a baffle plate 8 for the discharged bean paste is placed directly below the outlet 7 at the lower end to prevent it from stirring. Then, an upright short cylinder 9 is arranged on the outer periphery of the baffle plate 8 with a gap t therebetween, and the lower end opening 1 of the cylinder 9 is
0 in the middle of the settling tank 3, that is, the upper part and the funnel-shaped lower part 2
It is arranged so that it extends to the boundary between the two.
The short tube 9 has a length of approximately 1000 mm and an inner diameter of approximately 500 mm, and may be either a square tube or a cylinder, and the gap t may be approximately 50 mm. The short tube 9 and the baffle plate 8 are connected to a horizontal rod 15 provided at the upper end, and the horizontal rod 15 is supported by a cross horizontal frame 16 installed on the upper end of the outer tube 12. are supported concentrically around the center line. In addition, what is indicated by 17 in the figure is a connecting rod connecting the horizontal rod 15 and the baffle plate 8.
8 is a glass window for seeing through the internal state; 19 is a water inlet for preventing clogging; 20 is a valve for controlling the amount of bean paste discharged as the water level of the supernatant water 21 rises and falls; 22 is a float for operating the valve 20;
3 is a connecting string, 24 is a bean paste making machine, 25 is a bean paste particle sieve, 2
6 is a pump, 27 is a pipe, 28 is a vacuum dehydrator, 2
9 is a raw bean paste product, 30 is a bagging process, 31 is a measuring process, and 32 is a cold warehouse storage process.

``Effects'' Since the present invention is configured as described above, it is possible not only to efficiently and continuously separate the raw bean soup of 60 to 100 mesh or less, which is made by boiling and grinding beans, into supernatant water and thick bean soup. There is the advantage of being able to obtain a bean juice precipitation device that does not take up a large space, is simple, and does not require human labor. In particular, the present invention provides an outflow bean soup baffle plate so that its center is located directly below the lower end outlet of the downward bean paste supply pipe, and arranges an upright short tube around the outer periphery of the baffle plate at a distance t. Furthermore, since the downward supply pipe for bean paste and the above-mentioned upright short tube are supported concentrically, the bean paste flowing out from the supply pipe is supplied to the center of the baffle plate, and further from the periphery of the baffle plate to the upright short tube. Since the bean paste particles are evenly guided by the inner surface and flow down the short tube, the bean paste particles can be deposited evenly in the funnel-shaped lower part of the settling tank, and the bean paste can be easily taken out from the discharge port.

In addition, the flow rate of the bean paste that flows directly below the water surface from the supply pipe is suppressed by a baffle plate directly below the water surface, and the discharge direction is horizontal, so that the water surface is on the inner surface of a short cylinder whose inner diameter is larger than that of the supply pipe. Collision occurs at the bottom and the flow rate further decreases as it flows downward inside the same short tube, so even if the flow rate from the supply pipe is relatively high, the flow rate of the bean paste supplied into the sedimentation tank is effective. can be suppressed to
