Description

The present invention relates to conveyance system and purification apparatus sprouts.

  Conventionally, in order to ship the harvested bean sprout, the sprout was refined by the following processes. First, water washing is performed to remove the soil adhering to the harvested bean sprouts. The harvested bean sprouts are put in a basket, and the basket is dipped in a water tank containing a large amount of water to wash away the soil adhering to the bean sprouts, and then the bean sprouts in the basket are placed on the supply belt. The bean sprout is conveyed to the next bean sprout refiner in a state of being piled up on the supply belt. As a refining device, for example, the device described in Patent Document 1 removes unnecessary materials such as shells and debris attached to bean sprouts. The apparatus described in Patent Document 1 drops the sprouts lifted up by the scraping conveyor onto a first endless belt that is inclined upward in the moving direction. The bean sprouts that have dropped onto the first endless belt move downward due to their own weight and vibration and drop onto the second endless belt disposed below. On the other hand, unneeded items such as shells and debris attached to the bean sprout are removed from the bean sprout by vibration, adhere to the surface of the first endless belt, move upward together with the first endless belt, and are removed by the scraper. Even in the second endless belt, unnecessary substances are removed from the bean sprouts by the same operation as the first endless belt, and the second endless belt falls onto the lowermost transport belt. The bean sprouts from which unnecessary substances have been removed are conveyed from the lowermost conveying belt to the next process. The bean sprouts from which the shells, debris, and the like have been removed by the above-mentioned apparatus are removed, for example, by a refining apparatus described in Patent Document 2, or a bean sprouting apparatus described in Japanese Patent Application No. 2002-101800 proposed by the present applicant After being refined, such as arranging the bean sprouts in the same direction, they are packaged in a bag and shipped.

  However, in the apparatus of Patent Document 1, when bean sprouts are thrown into the apparatus in a piled state, the bean sprouts that come into contact with the first and second endless belts are removed by the vibration from the belt. The bean sprouts that were on top were not removed, and slipped down on the bean sprouts and transported to the next process. For this reason, it has been necessary to limit the amount of palm supplied even with the scraping belt. If the supply amount of bean sprouts is limited in this way, the bean sprouts transported in a piled state on the supply belt will stagnate on the scraping belt, resulting in poor purification efficiency. Further, in the above-described refining process, since it is performed by a separate refining device such as an unnecessary material removing device, a root removing device, an aligning device, etc., a transport belt for transporting sprouts processed by a certain refining device to another refining device The purification efficiency was poor, and a lot of space for refining the sprouts had to be secured.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a bean sprout purification apparatus that has high purification efficiency and can be purified in a space-saving manner.

According to invention of Claims 1 thru | or 7 , the bean sprout supplied to a conveying apparatus (conveyance part) is made to contain a water | moisture content in a sprout root part by the means which makes a root part of a sprout contain a water | moisture content. Then, the root part of the bean sprouts containing water is adsorbed on the transport surface of the transport device (transport part) by the capillary phenomenon. The conveyance surface is inclined, and the stem and young leaves having water repellency compared to the root part are less likely to be adsorbed to the conveyance surface through water, and therefore slide down the inclined surface due to the dead weight of the stem and young leaves. However, since the root part is adsorbed to the conveyance surface as it is, bean sprouts are always conveyed with the root facing upward with respect to the inclined surface. Thereby, since the head and root part of a bean sprout are conveyed to the following process toward a fixed direction, when deleting the root of a bean sprout as a next refining process, a root can be deleted easily.

  Hereinafter, the bean refiner of the present invention will be described. 1 and 2 are schematic views showing a bean sprout purification apparatus according to the present embodiment. In this bean sprout refining apparatus 1, a supply conveyor 2 for supplying bean sprouts harvested and washed with water to a supply unit 3 as a supply device is provided on the left side of the supply unit 3 in FIG. The bean sprouts on the supply conveyor 2 are dropped onto the pull-in table 2a. The vibration pulling table 2a is connected to a vibration plate 4 to be described later, and a vibration for moving the sprouts to the supply belt side is given by a vibration device attached to the vibration plate 4. The bean sprouts on the pull-in table are supplied to the supply belt 3a while being loosened by the vibration. The supply belt 3a is an endless belt that is approximately three times as wide as the supply conveyor 2, and is rotatably suspended by a plurality of rollers. One of the rollers is a driving roller, which transmits a driving force from a belt driving motor 100 provided on the right side in FIG. 2 to rotate the supply belt 3a. The supply belt 3a has a curved portion that is inclined in an arc shape that is largely curved upward. A pulley 102 is attached to both ends of the curved portion so that the supply belt 3a is not bent. In the curved portion of the supply belt 3a, a portion that receives the sprouts of the transport unit 5 as a transport device is provided so as to be surrounded by the endless belt. The conveyor 5 is provided with a conveyor belt 5a having the same width as the supply belt 3a. The conveyor belt 5a is an endless belt, and is rotatably suspended by a plurality of rollers. One of the rollers is a driving roller, which transmits a driving force from a driving source (not shown) to rotate the conveying belt 5a. The rear end roller 5d of the transport belt 5a is provided in a portion surrounded by the curved portion of the supply belt 3a, and the front end roller 5c of the transport belt 5a is provided above the rear end roller 5d. The bean sprouts transport surface is inclined. The inclination angle Q of the conveyor belt 5a can be changed by the inclination switching cylinder 5b depending on the type of sprouts. And the diaphragm 4 as a receiving member which receives the bean sprouts which fell from the conveyance part 5 is provided in the diagonally back of the rear-end roller 5d. The diaphragm 4 also has the same width as the supply belt 3a and is inclined upward toward the curved portion. A vibration generating device 4a is attached to the rear surface of the diaphragm 4, and generates vibrations that move the sprouts to the right side in FIG.

  Next, the bean sprouts supply part which supplies bean sprouts to a conveyance part in this embodiment is demonstrated using FIG. The bean sprouts that have been harvested and washed with water are supplied to one end of the supply belt 3 a by the supply conveyor 2 in an overlapped state. The supplied bean sprouts move up to the upper part of the curved portion by using the supply belt 3a to climb the slope curved in an arc shape together with the belt. The sprouts that have moved to the upper part of the curved part fall off from the supply belt 3a due to their own weight and fall off to the transport surface near the rear end roller 5d of the transport part. About 10 liters of water is sprayed on the conveyor belt surface of the conveyor 5 by the shower ring unit 7 per minute to adhere the water. The root part of the bean sprout has high water absorption and is likely to contain a lot of water. When the sprout root part falls on the transport belt 5a, the sprout root adheres to the transport belt 5a due to the capillary phenomenon. At this time, the conveyance belt 5a is made of a hydrophilic material, or coated with a hydrophilic material on the belt surface so as to increase the adhesion of water so that the roots of the sprouts can be easily adsorbed. Yes. Further, when the sprout root is dropped on the transport belt 5a by the shower ring unit 7 while the sprout is dropped on the transport belt of the transport unit 5, the root of the sprout is caused by a capillary phenomenon. Alternatively, it may be attached to the conveyor belt 5a. And the adsorbed bean sprout climbs the slope of the transport unit and is transported to the next step. On the other hand, the bean sprouts that have not been adsorbed to the conveyor belt 5 a slide on the slope of the conveyor belt 5 a and fall on the diaphragm 4. The diaphragm 4 is vibrated in a direction in which the bean sprout is moved to the back side of the supply unit 3, and the bean sprouts that have fallen on the diaphragm 4 are moved to the back side of the supply unit by vibration, and the diaphragm 4 And is returned to the supply belt 3a again. The bean sprout returned to the supply belt 3a again climbs the arc-shaped slope as described above, is supplied to the transport unit 5, and is adsorbed or dropped on the transport belt 5a. The belt is returned to the supply belt 3a while moving to the back side of the supply unit. In this manner, as shown by arrows in FIG. 3, the bean sprouts are dispersed in the width direction of the supply belt 3a while being stirred. Thereby, the bean sprouts supplied to the conveyance part 5 are distributed and supplied in the width direction of the conveyance belt 5a. Further, as shown in FIG. 3, the bean sprouts are agitated many times before adhering to the conveyor belt 5a, and unnecessary substances such as shells, debris and fine roots can be removed from the bean sprouts. The removed unnecessary material is removed by a scraper or the like that contacts the supply belt 3a. At first, since the bean sprouts supplied from the supply conveyor 2 to the supply unit 3 are in a state of being stacked in many layers, the sprouts are excessively supplied to the transport belt 5a, and most sprouts fall off from the transport belt 5a. However, the density of sprouts becomes sparser toward the back side of the supply belt 3a, and can reliably adhere to the transport belt 5a.

  Next, the bean sprouting means will be described. As shown in FIG. 4, the bean sprouts 200 adsorbed on the conveyor belt 5a have a certain slope Q or more in the conveyor so that the roots are aligned in the transport direction. First, the bean sprout 200 supplied from the supply unit 3 and adsorbed onto the transport belt 5a is adsorbed in a discrete direction. The bean sprout root part 200a is water-absorbing and adsorbed on the transport belt, but the sprout head part 200b is a young leaf, so it is more water-repellent than the root part and hardly adsorbs on the belt. . Then, the sprout head 200b slides in the direction opposite to the transport direction due to its own weight. As a result, the bean sprout 200 adsorbed on the transport belt is transported with the root 200a facing the transport direction. Alternatively, the bean sprouts may be supplied to the transport unit so as to vibrate the transport belt 5a in the vicinity of the bean sprout receiving unit to promote the above-described movement so that the palm root part 200a can be more easily directed toward the transport direction. In this way, the bean sprouts whose roots face in a certain direction are transported by the transport belt 5a and are transported to the next process by the transporting conveyor. As described above, the root part of the bean sprout is conveyed in a certain direction, so that the root deletion process of the next process can be easily performed.

In the present embodiment, under flow of transport unit 5 is provided with a root deletion means. This example will be described with reference to FIG. This means is provided with a blade-shaped cutter 8 at a position facing the tip roller 5c. The cutter 8 can contact and separate from the transport belt 5a. Usually, the cutter 8 is located at a position where a slight gap is formed between the cutter 8 and the conveyor belt 5a. This gap is set so that the bean sprout root 200a passes but the bean sprout stem does not pass. The bean sprouts 200 adhering to the conveyor belt 5a move upward as the belt moves, and are sandwiched between the cutter 8 and the conveyor belt 5a, and stop moving. When a certain amount of bean sprouts 200 is sandwiched between the cutter 8 and the conveyor belt 5a, the cutter 8 is brought into contact with the conveyor belt 5a, and the root is cut from the bean sprouts. The bean sprout from which the root portion has been removed (hereinafter, bean sprout body) loses the adsorption force on the conveyor belt and slides down the inclined surface of the conveyor belt. The bean sprouts main body that has been slid down falls again on the diaphragm 4 and is moved to the back side, and then is fed into the supply unit 3. The introduced bean sprout body climbs the curved portion of the supply belt 3a and falls off on the transport belt 5a. However, since the root part of the bean sprout is cut, it does not adhere to the transport belt 5a and slides on the transport belt. Falls and is received by the diaphragm 4. The bean sprout body received by the diaphragm does not move to the back side (right side in FIG. 2) of the supply belt 3a due to the vibration of the diaphragm, but slides down the slope of the diaphragm 4 and again supplies the belt 3a. It is thrown into. By repeating such an operation, the bean sprout from which the root has been removed moves to the innermost side of the supply belt 3a (the rightmost side in FIG. 2). The bean sprout body that has moved to the farthest side is detached from the diaphragm 4 by the above-described operation, and is moved to the vibration carry-out table 9 a connected to the diaphragm 4 by the vibration of the diaphragm 4. The bean sprout body on the vibration carry-out table 9a is oscillated and dropped onto the carry-out belt 9 and conveyed to the next step.
On the other hand, when the root part is removed from the bean sprout, the cutter 8 is slightly separated from the conveyor belt 5a, and again, as described above, a slight gap is formed again between the cutter 8 and the conveyor belt 5a. A palm root is also sandwiched between the belt 5a. Root deleted from sprouts, provided further down stream of the cutter 8, is removed from the conveyor belt by a scraper which is in contact with the conveyor belt.
While continuing the roots removing step as described above, on the surface 8a of the upper stream side of the cutter, the insolubles adhere, it will block the gaps between the cutter 8 and the conveyor belt 5a, the cutter 8 the conveyor belt 5a There was a case where the bean was not sandwiched between and the root part could not be removed from the bean sprout. Therefore, in the present embodiment, a removing means for removing the deposits attached to the cutter 8 is provided. As the removing means, as shown in FIG. 5, the brush 10 is provided so as to contact the surface 8 a of the cutter 8. The brush 10 has an operation trajectory as shown in FIG. 5 so that the brush tip comes into contact with the tip of the cutter 8 and the conveyor belt 5a. After the cutter 8 cuts the bean sprout five times, the tip of the brush 10 is moved so as to take a locus as shown in FIG. 5, and the cutter surface 8a and the cutter tip are brushed. Unnecessary matter blocking the gap between the cutter 8 and the conveyor belt 5a is removed.

  In addition, the bean sprout refiner of this embodiment can purify bean sprouts, black mappe sprouts, small soybean sprouts, soybean sprouts, etc., and purify sprouts regardless of the thickness, thinness, and length of the sprouts. Can do. Moreover, when this apparatus is used, it becomes possible to refine | purify a sprout of about 1000 kg per hour.

According to this embodiment, the bean sprouts supplied to the supply part 3 as a supply apparatus climb the curved part by the supply belt 3a. The bean sprout that has moved to the upper part of the curved part is separated from the supply belt 3a by its own weight and falls to the transport unit 5 as a transport device. Some bean sprouts that have fallen to the transport unit are transported to the next process as they are by the transport unit, and some sprouts are dropped from the transport unit 5. The sprouts that fall off are received by the diaphragm 4 as a receiving member. The bean sprouts on the diaphragm 4 are vibrated and moved by a vibration device provided on the diaphragm 4 so as to be uniformly distributed in the width direction on the supply belt 3a. The bean sprout that has been moved by vibration is supplied again from the diaphragm 4 to the supply belt 3a and moves again to the bending portion. By repeating such an operation, the bean sprouts are agitated and shells, debris, fine roots, etc. adhering to the bean sprouts can be removed. Moreover, even if the bean sprouts are put into the apparatus as they are, the sprouts can be dispersed uniformly in the width direction on the supply belt 3a by repeating the above-described operation. As a result, the sprouts that are piled up as in the past do not stagnate on the scraping belt, and the purification efficiency does not deteriorate. Moreover, it is not necessary to provide the above-described scraping belt, the space for the bean sprout refining process can be narrowed, and the cost of the bean sprout refiner can be reduced.
Moreover, according to this embodiment, the bean sprouts supplied to the conveyance part 5 conveyed to the next process are conveyed in the state disperse | distributed to the width direction of the conveyance belt 5a. Thereby, it is not necessary to provide a device for dispersing the bean sprout before purifying the bean sprout in the next step, and the purification efficiency can be increased. Moreover, the space of the refinement process of a bean sprout can be narrowed, and the cost of a bean sprout refiner can be reduced.
Further, according to the present embodiment, the transport unit 5 is also provided with bean alignment means. As a result, the bean sprouts from which unnecessary items such as shells and debris have been removed have their heads and roots oriented in a certain direction. Thereby, a bean sprout root can be easily deleted as the next purification step.
