Description

[Detailed Description of the Invention] The present invention provides dregs mixed in harvested bean sprouts,
The present invention provides an apparatus for refining bean sprouts by removing shells, thin roots, etc.

Harvested bean sprouts contain about 10% by weight of the raw material bean shells, dregs, and unnecessary substances such as thin roots. In order to remove these unnecessary substances from harvested bean sprouts, the conventional method was to soak the sprouts in a tank containing a large amount of water to allow the bean shells and dregs to settle and be removed.

However, this conventional method not only requires a large amount of water, but also requires a large amount of space to accommodate large-sized water tanks within the industry.
A further disadvantage of the conventional method was that bean sprouts that were washed with water had a significantly shorter shelf life.

The present invention provides a completely new apparatus for refining bean sprouts that is fundamentally different from conventional methods of refining bean sprouts.

The bean sprout refining device according to the present invention does not require a water tank or any water at all, and has the great advantage that it not only significantly saves resources, but also occupies an extremely small amount of space. There is.

Another remarkable feature is that the harvested bean sprouts are not washed with water as many times as in the past, so the shelf life of the commercial product is significantly extended.

Hereinafter, the apparatus according to the present invention will be specifically explained based on the illustrated embodiments.

In FIGS. 1 to 3, reference numeral 1 denotes a frame forming a vibrating frame, and rollers 2 and 3 are rotatably supported on this vibrating frame 1. As shown in FIGS.

A perforated endless belt 4 is stretched around the rollers 2 and 3. The roller 3 is connected by a geared motor 5 and a flexible shaft 6,
It is rotated by the rotation of the geared motor 5, and causes the perforated endless belt 4 to run in the direction of the arrow shown. The vibrating frame 1 is provided with side guides 7 rising along both edges of the perforated endless belt.

A stand frame 8 is provided below the vibrating frame 1, and two crank disks 9 are rotatably supported on the side surfaces of the stand frame 8 in a left-right symmetrical manner.

Below the stand frame 8 is a geared motor 10.
A pulley 11 is fixed to the rotating shaft of this geared motor.

On the other hand, a pulley 12 is fixed to the shaft to which the crank disk 9 on the left side in FIG. 1 is fixed.
A driving belt 13 is stretched between the pulleys 11 and 12, and the rotation of the geared motor 10 causes the crank disk 9 to rotate in the direction of the arrow.

Four bearings 14 are fixed to the lower surface of the vibrating frame 1 in correspondence with the crank disk 9 of the base frame 8, and a pin 15 pivotally supported by the bearings 14 is eccentrically fixed to the crank disk 9. ing. Therefore,
The geared motor 10 is rotated and the drive belt 1
3, when the crank disk 9 rotates in the direction of the arrow, the vibration frame 1 is given vibration by the crank movement between the crank disk 9 and the pin 15 fixed eccentrically from the center of rotation. .

The geared motor 10 is equipped with a periodic transmission device that periodically changes the rotational speed during one rotation, and is adjusted so as to provide a high rotational speed to the pulley 9 when upwardly displacing the vibration frame 1. ing.

Between the upper and lower running areas of the perforated endless belt 4, a slag receiver 16 is disposed in an inclined manner with the discharge side facing down like a sink. Also, perforated endless belt 4
A chute 17 is provided at one end of the upper running area to drop the bean sprouts to be refined onto the belt 4 in this running area, and below this, one edge is connected to the running surface of the endless belt 4. A sludge removal chute 18 equipped with a scraper that comes into contact with the slag chute 18 is provided.

A chute 19 for discharging bean sprouts is provided on the opposite side of the running range of the endless belt 4.

A shower 20 is provided along the higher side wall of the inclined slag receiver 16 to wash away the sludge that falls onto the slag receiver 16.

The operation of the apparatus having the configuration described above will be explained. Bean sprouts to be refined are supplied from a chute 17 to the perforated endless belt 4 which is running in the direction of the arrow by the driving force from the geared motor 5.

Vibration frame 1 with endless belt 4 attached
The bean sprouts placed on the endless belt 4 are vibrated at a large speed when displaced upward by the action of a crank disk 9 rotated by a geared motor 10 with a periodic transmission. is given a vibration thrown diagonally upward as indicated by the arrow in FIG.

Therefore, even though the endless belt 4 travels in the direction of the arrow B, the bean sprouts on the belt 4 are sent in the direction of the arrow M in small increments.

When the bean sprouts are subjected to such movement from the endless belt 4, foreign substances such as bean shells, thin roots, and slag mixed in with the bean sprouts are separated from the bean sprouts and flowed through the holes in the endless belt 4 onto the slag receiver 16. Fall. The thus purified bean sprouts are discharged from the chute 19.

The shells and root chips that have fallen into the slag receiver 16 are washed away by the shower 20.

In addition, bean shells and the like that are stuck in the holes of the perforated endless belt 4 are removed by the sludge removal chute 18 equipped with a scraper that is in contact with the belt, so that the endless belt 4 has a clean surface again. Returning to the driving range.

In the embodiment described above, the bean shells and slag attached to the perforated endless belt 4 are removed by the sludge removal chute 18 equipped with a scraper, but this is done by removing the slag from the belt 4 using a brush or the like. Any suitable form may be adopted as long as it can be removed.

Further, the slag falling into the slag receiver 16 is washed away by the shower 20, but it goes without saying that an appropriate device such as a scraping plate may be used for this as well.

Further, in the illustrated embodiment, the direction in which the endless belt 4 runs and the direction in which the sprouts are transported are reversed, but they may be in the same direction.

In addition, in the embodiment described above, a crank mechanism in which a geared motor 10 with a periodic transmission is used as a drive source is used to vibrate the vibrating frame 1, but this also means that the bean sprouts on the belt 4 are moved in small increments. Any suitable shape may be used as long as it gives vibrations that cause a tossing motion.

FIG. 4 shows another vibration excitation mechanism for the vibration frame 1, which will be explained below.

In FIG. 4, the vibrating frame 1 is connected to the stand frame 8 by being pivoted on each side by three parallel diagonal levers 21, and a compression spring 22 disposed in a direction perpendicular to the levers 21 is connected to the base frame 8. It is interposed between both frames 1 and 8.

23 is a motor attached to the stand frame 8;
Reference numeral 24 denotes a vibrator attached to the vibrating frame 1, and a belt 13 is stretched between pulleys 11 and 12 fixed to a rotating shaft of the motor 23 and the vibrator 24. In addition, 25 is a pulley with a built-in motor.
It provides the driving force for running the belt 4.

The other configurations are the same as those shown in FIGS. 1 to 3, and corresponding parts are given the same reference numerals as in FIGS. 1 to 3, and their explanation will be omitted.

In the apparatus shown in FIG. 4, when the motor 23 is rotated, the vibrating machine 24 is driven and vibration is applied to the vibrating frame 1. Since the vibration frame 1 is connected to the vibration frame 1 and the diagonal spring 22 is interposed, the vibration given by the vibration exciter 24 is transmitted to the vibration frame 1.
, vibration in the direction of the arrow in FIG. 4 is applied.

This causes the bean sprouts on the endless belt 4 to move in the direction of the discharge chute 19, causing a small upward movement as explained in FIGS. 1 to 3.

According to tests conducted by the present inventors using actual equipment, a large number of circular holes with a diameter of 8 mm were made in an endless belt made of rubber or plastic with a spacing of 13 mm between the centers of the holes for ordinary Matupe bean sprouts. When the beans were transferred for 12 to 15 seconds over a distance of 3 meters while applying vibrations of 300 to 450 times per minute with a vibration width of ~15 mm, the bean sprout shells, dregs, root chips, etc. It was surprisingly easy to remove. Incidentally, the shape of the holes in the endless belt 4 does not have to be circular but may be any suitable shape.

As explained in detail above, the device according to the present invention can easily purify bean sprouts without using a large tank and large amounts of water as in the conventional method, and has revolutionary efficacy. .

Moreover, since water is not used as in the conventional method, the bean sprouts have an extremely long shelf life after purification.

Further, according to the present invention, since the belt surface is always kept clean with the belt cleaning tool, bean sprouts can be purified continuously and efficiently.

Although the apparatus described above uses only one perforated endless belt, a plurality of endless belts 4 are used as shown in FIG. 4'', the bean sprouts transported on the endless belt 4 fall in a waterfall shape at these stages 4' and 4'', and the upper layer and lower layer are reversed. Since the warmed bean sprouts come to the lower layer and touch the belt 4, the bean shells and dregs attached thereto are removed evenly and well.
