One embodiment of the present invention will be described below.
A seed disinfection facility that is a hot water / cooling facility is provided with a hot water disinfection device A, a seed cooling device B, and a drying device C in order from the previous process to the subsequent process. The hot water disinfection apparatus A is provided with a hot water disinfection tank 1 serving as a box-shaped hot water tank, and a circulating transfer apparatus 3 serving as a hot water transfer apparatus for circulating and transporting a large number of seed buckets 2 is provided above the hot water disinfection tank 1. Yes. In addition, the said hot water disinfection tank 1 becomes a structure which can accommodate 11 seed buckets 2 in a row. In addition, the seed bucket 2 is configured to contain a net-like seed bag P for storing seeds for each predetermined amount.

  The circulating transfer device 3 has a lowering device 3d for lowering the seed bucket 2 which forms a large number of holes on the transfer start end side and immersing the seed bucket 2 in the hot water in the hot water disinfection tank 1, and a seed immersed in the hot water disinfection tank 1. A transfer device 3a for transferring the bucket 2, a raising device 3b for raising the seed bucket 2 immersed in the hot water disinfection tank 1 on the transfer end side, and a seed bucket 2 raised by the raising device 3b to the lowering device 3d And a return device 3c.

  The transfer device 3a includes a guide rail portion 4 that receives an edge portion 2a provided at the upper end of the seed bucket 2 from the lower left and right sides, and a chain-type transfer conveyor 5 for transferring the seed bucket 2 at the transfer start end portion. Provided. The transfer conveyor 5 includes a pressing protrusion 5a that transfers the seed bucket 2 to an appropriate position in the circuit path, and the pressing protrusion 5a is fixed to the right and left of the edge of the seed bucket 2 in the horizontal direction. The seed bucket 2 is transported by pushing it, and the seed bucket 2 on the lower transfer side is sequentially pushed by the seed bucket 2 on the upper transfer side, and the seed bucket 2 is transferred in the hot water disinfection tank 1. Yes.

  The elevating device 3b is provided with a chain type elevating conveyor 6 provided on the right and left with lifting projections 6a on which the fixed shaft 2b of the seed bucket 2 is caught at the end (transfer end) of the guide rail portion 4. Therefore, by driving the lifting conveyor 6, the fixed shaft 2b of the seed bucket 2 at the terminal end (transfer terminal) of the guide rail portion 4 is lifted by the lifting projection 6a, and the seed bucket 2 is lifted. The ascending conveyor 6 is triangular in a side view provided with an oblique movement path (circulation path) that moves in the transfer direction of the transfer device 3a as the seed bucket 2 is raised from the rising start position where the lifting protrusion 6a is caught by the fixing shaft 2b. It goes around with the round path of the shape. Further, reversing cams 7 for reversing the seed bucket 2 in the middle of the oblique movement path are provided on the left and right, and when the seed bucket 2 is lifted, the reversing cam 7 is one of the fixed shafts 2b on the edge 2a of the seed bucket 2. By pressing down on the side (the transfer direction side of the transfer device 3a, the seed cooling device B side) from the upper side, the seed bucket 2 is directed toward the seed cooling device B with the fixed shaft 2b as a fulcrum. The seed bag P in the seed bucket 2 is discharged to the cooling bucket 8 of the seed cooling device B. A guide plate 9 is provided to guide the hot water dripping from the seed bucket 2 rising or reversing from the upper end of the hot water disinfection tank 1 to the position of the reversing cam 7 to the hot water disinfection tank 1. By this guide plate 9, the hot water dripping from the seed bucket 2 is returned to the hot water disinfection tank 1 to suppress the release of heat in the hot water disinfection tank 1, and the hot water dripping into the cooling tank 10 of the seed cooling device B. Decrease in cooling efficiency can be prevented.

  The return device 3c and the lowering device 3d are configured to include a chain-type return conveyor 11 provided on the right and left with a transporting protrusion 11a on which the fixed shaft 2b of the seed bucket 2 is hooked. The conveying protrusions 11a are arranged opposite to the front and rear in the circumferential direction of the return conveyor 11, and are configured to hold the fixing shaft 2b between the front and rear protrusions 11a. Accordingly, the seed bucket 2 that has been raised to the upper end of the lifting conveyor 6 of the lifting device 3b is moved down to the transfer start end side of the transfer device 3a after the return conveyor 11 is inherited, and then lowered to the middle of the lowering path. At the seed bag supply position r. At the seed bag supply position r, the seed bucket 2 is positioned above the hot water disinfection tank 1, and an operator supplies the seed bag P to the seed bucket 2. When the transfer device 3a is actuated to create a space for accommodating the seed bucket 2 at the transfer start end, the return conveyor 11 is actuated to lower the seed bucket 2 at the seed bag supply position r, It is dropped and supplied from the lower end of the return conveyor 11 to the hot water disinfection tank 1. Note that the seed bucket 2 waiting at the seed bag supply position r is inclined such that the lower front side contacts the guide 12 attached to the hot water disinfection tank 1 and the upper opening portion faces the front side. Thereby, an operator can supply seeds (seed bags P) to the seed bucket 2 easily. Further, since the seed bucket 2 is tilted, the seed bucket 2 can be set to a height at which the seed bucket 2 is not immersed in the hot water of the hot water disinfection tank 1 and the height of the opening of the seed bucket 2 can be set as low as possible. It is easy to supply seeds (seed bags P) to the bucket 2.

  Further, when the seed bucket 2 at the seed bag supply position r is lowered and dropped from the lower end of the return conveyor 11 to the hot water sterilization tank 1, the edge 2a of the seed bucket 2 collides with the guide rail portion 4 to generate noise. There is a possibility that the edge 2a is deformed due to the occurrence or impact. Therefore, the ridge raised on a part of the bottom surface of the hot water sterilization tank 1 so that the bottom of the seed bucket 2 contacts the bottom surface of the hot water sterilization tank 1 before the edge 2a of the seed bucket 2 collides with the guide rail part 4. If the bottom part of the seed bucket 2 that falls on the raised part first comes into contact with the raised part, the impacting sound is suppressed because the colliding part is underwater, and the edge 2a is prevented from being deformed and circulated and transferred. The transfer of the seed bucket 2 by the device 3 can be optimized.

  The transfer device 3a intermittently transfers a plurality of seed buckets 2 simultaneously, whereas the return device 3c and the lowering device 3d continuously transfer a single seed bucket 2 to the seed bag supply position r. It is the composition to do. Therefore, the transfer speeds of the return device 3c and the lowering device 3d are set faster than the transfer speed of the transfer device 3a. By reducing the number of empty seed buckets 2, the cost can be reduced and the temperature of the hot water disinfection tank 1 is increased. Since the number of empty seed buckets 2 is small, the empty seed bucket 2 is less likely to get in the way when the operator visually recognizes the disinfection status and operation status in the hot water disinfection tank 1.

  Moreover, the transfer of the seed bucket 2 that is intermittently transferred by the transfer device 3a is set so that the time in the transfer stop state is longer than the time during the transfer. Therefore, the seed bucket 2 can be retained for a long time above the hot water outlet 13 described later in the hot water disinfection tank 1, and the sterilizing effect of the seed can be enhanced. In addition, by increasing the transfer stop time of the transfer device 3a, the stop time of the ascending device 3b and the descending device 3d can be set longer so that the seed bucket 2 is stopped at the seed bag supply position r. The time can be set longer, and the seed (seed bag P) can be easily supplied to the seed bucket 2 that is stopped. The transfer stop time of the transfer device 3a can be changed by adjusting means, and the total time that the same seed bucket 2 is immersed in the hot water disinfection tank 1 can be changed by changing the transfer stop time. Therefore, the disinfection time of seeds can be changed according to the seed varieties (for example, soaked glutinous rice seeds are soaked for 10 minutes and soaked glutinous rice seeds for 6 minutes). Thereby, immersion time can be changed easily, without changing the transfer speed during transfer of the transfer apparatus 3a. The transfer device 3a, the lifting device 3b, the return device 3c, and the lowering device 3d are operated by a common drive source (motor).

  Further, when an emergency stop occurs due to a failure or inspection of the apparatus during seed disinfection work, control is performed to measure the emergency stop time and add it to the disinfection time. Therefore, the stop time of the intermittent transfer is shortened by the transfer device 3a by the amount of the emergency stop. At this time, if the set disinfection time is reached during an emergency stop, an alarm means such as a lamp warns. Therefore, seed damage such as seed cracking can be prevented by immersing the seed in hot water longer than necessary.

  At the bottom of the hot water disinfection tank 1, hot water jets 13 are arranged at predetermined intervals, and the hot water jet 13 is positioned below the stop position of the seed bucket 2 that is stopped while being intermittently transferred. The hot water is jetted out and the hot water passes through the hole of the seed bucket 2 and acts on the seed (seed pod) accommodated in the net-like seed bag P. In addition, the bottom part of the hot water disinfection tank 1 is configured to be inclined downward toward the intermediate part in the front-rear direction, and the drainage groove 14 is configured in the intermediate part.

  If all the hot water spouts 13 are directed to the front side (seed input side), the temperature of the hot water at the front side (seed input side) in the hot water disinfection tank 1 can be increased, and the hot water disinfection is performed in the seed bucket 2. When seeds are introduced into the tank 1, it is possible to suppress the temperature drop of the hot water around the charging part, and the temperature of the hot water in the hot water disinfection tank 1 can be made uniform.

  In the subsequent process of the hot water disinfection tank 1, a seed cooling device B is provided via a supply chute 15. The seed cooling device B is provided with a seed cooling tank 10 that is long in the front-rear direction on the rear side of the supply chute 15, and the seed cooling tank 10 is provided with a plurality of cooling buckets 8 from the front side toward the rear side. The cooling bucket 8 forms a large number of holes and is supported by a horizontal axis 8a so as to be rotatable in the horizontal axis. Then, when the cooling bucket 8 rotates and reverses about the shaft 8a, the seed bag P stored in the cooling bucket 8 is stored in the next cooling bucket 8. Therefore, the cooling bucket 8 and the shaft 8a constitute a cooling transfer device. In addition, the cooling bucket 8 is rotated twice small when reversed, and the seed bag P is reliably discharged. A partition wall 16 for partitioning the inside of the tank is provided for each storage portion of each cooling bucket 8 in the cooling tank 10, and the partition wall 16 is higher on the seed discharge side (discharge chute 17 side). The cooling water supply port 18 for supplying new water to the cooling tank 10 supplies water at the end of the seed discharge side (discharge chute 17 side) in the seed cooling tank 10. The cooling water from the water supply port 18 is sequentially supplied from the discharge side section partitioned by the partition wall 16 in the cooling tank 10.

  When the sensor detects that the seed bucket 2 has been lifted by the lifting device 3b and arrived just before being reversed by the reversing cam 7, the cooling bucket 8 closest to the hot water disinfection device A is reversed and then returned to its original state. The seed bucket 2 rises and is reversed by the reversing cam 7. Thereby, the seed of the cooling bucket 8 can be supplied to the next cooling bucket 8 immediately before the seed is supplied from the seed bucket 2 to the cooling bucket 8, and the cooling time of the seed by the cooling bucket 8 can be extended. The cooling effect can be enhanced.

  The volume of the cooling bucket 8 is set larger than the volume of the seed bucket 2. Therefore, since the volume of the seed bucket 2 is small, it is possible to efficiently use hot water by reducing unnecessary portions in the hot water disinfection tank 1 where the seed bucket 2 is not supplied. Moreover, since the volume of the cooling bucket 8 is large, stirring of seeds is facilitated by air from an air outlet 19 described later, and the cooling effect is enhanced.

  In addition, an air ejection pipe 20 is provided below the cooling bucket 8 of the cooling tank 10 so that air is supplied to the air ejection port 19 by a blower 21 and the air is ejected toward the cooling bucket 8 being immersed. Yes. Moreover, the hot water disinfection tank 1 is also provided with an air ejection pipe 19, and the air ejection pipe 19 is arranged so as to intersect (orthogonally) in a plan view above the hot water pipe 22 provided with the hot water ejection port 13. . Since the hot water pipe 22 extends in the longitudinal direction (front-rear direction) of the hot water disinfection tank 1 and the hot water outlet 13 ejects hot water to the left and right, convection in the short direction (left-right direction) of the hot water disinfection tank 1 It is generated uniformly over the whole area, and the temperature unevenness in the hot water disinfection tank 1 can be suppressed. The air ejection pipe 19 is located below the various child buckets 2 to be stopped, and all the seeds can be evenly stirred by ejecting air toward the various child buckets 2.

  The blower 21 is common to the cooling tank 10 and the hot water disinfection tank 1, and a long contact tube 23 is provided before and after contacting the air jet pipe 19 of the hot water disinfection tank 1 on the outer surface (side surface) of the hot water disinfection tank 1. Air is supplied through With this contact tube 23, the temperature of the air supplied to the hot water disinfection tank 1 can be raised, and the temperature drop in the hot water disinfection tank 1 is prevented.

Next, the seed disinfection process will be described.
A net-like seed bag P containing seeds is supplied to the seed bucket 2 stopped at the seed bag supply position r in the middle of the lowering device 3d. Then, the seed bucket 2 is lowered from the seed bag supply position r into the hot water disinfection tank 1 by the lowering device 3d and immersed in the hot water.

  In the hot water disinfection tank 1, the seed bucket 2 is transferred by the transfer device 3a, and the transfer device 3a is intermittently driven. The seed bucket 2 stops at a position facing the hot water jet 13 and is exposed to the hot water sprayed in the stopped state, thereby promoting the disinfection action of the seeds in the seed bag P.

  The seed bucket 2 transferred while stopping for a set time at each hot water outlet 13 is pulled up by the lifting device 3b on the transfer end side. Then, the seed bucket 2 is reversed by the reversing device 7 in the middle of the ascending device 3 b, the seed bag P in the seed bucket 2 is discharged, passes through the supply chute 15, and enters the cooling bucket 8 on the start end side of the cooling tank 10. Supplied.

  The emptied seed bucket 2 is subsequently transferred upward by the ascending device 3b, then intermittently transferred above the hot water disinfection tank 1 toward the transfer start end side by the returning device 3c, and again supplied by the descending device 3d to the seed bag. Circulated and transferred to position r.

  The circulating transfer device 3 may be configured to continuously drive at a low speed instead of intermittent driving.

  The seed bag P supplied to the cooling bucket 8 of the cooling tank 10 is cooled by cooling water. The cooling bucket 8 is configured to be interlocked with the intermittent drive of the circulating transfer device 3, and is rotated and reversed before the next seed bag P is supplied from the hot water disinfection tank 1 to the seed cooling tank 10, and the seed is transferred to the next cooling bucket 8. The bag P is supplied and the seed bag P from the hot water disinfection tank 1 is received. That is, the seed bag P is sequentially transferred to the next cooling bucket 8 by sequentially rotating and reversing from the cooling bucket 8 on the cooling end side, and the seed bag P from the hot water disinfection tank 1 is transferred to the cooling bucket 8 on the cooling start end side. I accept it.

  And the seed bag P which passed the several cooling bucket 8 sequentially is discharged | emitted from the discharge chute 17, and is dried with the drying apparatus C of the next process.

  According to this seed disinfection device, it is possible to efficiently disinfect hot water continuously while transferring a plurality of seed buckets 2 by a hot water disinfection tank 1 that is long in the front and back, and seeds are transferred from the hot water disinfection device A to the seed cooling device B. The bag P can be supplied easily.

  In addition, since the circulating transfer device 3 is intermittently driven every set time, the time for one seed bucket 2 to be immersed in hot water can be made constant, and since it is exposed to hot water at every stop, a large number of seed bags P And uniform disinfection can be performed efficiently. Since the cooling bucket 8 and the circulating transfer device 3 are driven in conjunction with each other, the time for immersing the seed bag P in the cooling water can be made constant, and a large number of seed bags P can be uniformly cooled. .

  In addition, by arranging the hot water spout 13 at every set interval over the entire hot water disinfection tank 1, temperature unevenness in the hot water disinfection tank 1 is prevented, and the seeds of the seed bag P in the seed bucket 2 penetrate the hot water. It can equalize and enhance the hot water sterilization effect. In addition, by intermittently transferring the seed bucket 2 in the hot water disinfection tank 1, seed immersion and water separation are quickened, the immersion sterilization time becomes accurate, and the sterilization effect can be enhanced. In other words, in the present embodiment, one seed bucket 2 is stopped and immersed above every 10 hot water jets 13.

  Moreover, by jetting air into the cooling tank 10, the temperature rise of the cooling water in the cooling tank 10 can be prevented from being reduced, and the cooling effect can be increased.

  Further, since the cooling bucket 8 is driven and reversed every predetermined time and the seed bag P is transferred while being cooled for a predetermined time in the cooling water, the cooling effect can be enhanced.

Next, the hot water and cooling water supply paths used for the hot water disinfection tank 1 and the cooling tank 10 will be described with reference to FIG.
A hot water overflow tub 24 is provided in the hot water sterilization tank 1, and the hot water overflowed to the hot water overflow tub 24 is discharged to the outside. Further, a hot water discharge port 25 different from the hot water overflow basket 24 is provided in the hot water disinfection tank 1, and supplied from the hot water discharge port 25 to the switching valve 27 through a hot water return path 26 serving as a return path. Accordingly, the hot water discharge port 25 is switched to a state in which hot water is discharged by switching the switching valve 27.

  Then, hot water from the hot water return path 26 is supplied to a hot water supply path 28 serving as a hot water supply path via a switching valve 27. The hot water supply passage 28 is provided with a pump 29 and an in-line heater 30 serving as a heater. The in-line heater 30 has a configuration in which steam is supplied from a boiler 31 through a steam supply path 32 having various valves to obtain heat. Hot water is supplied from the hot water outlet 13 to the hot water disinfection tank 1 through the hot water supply passage 28. The temperature of the hot water in the hot water disinfection tank 1 is controlled by the hot water temperature sensor 33 to be about 60 ° C.

  Further, the cooling water overflowed from the cooling tank 10 is returned to the recovery tank 36 via a cooling water overflow rod 34 and a reflux path 35 serving as a cooling water overflow path. The cooling water in the collection tank 36 is supplied to a water supply path 37 that serves as a water supply path. The water supply path 37 includes an on-off valve 38 and supplies water to the switching valve 27. And it is the structure which supplies the water of the water supply path 37 to the hot water supply path 28 by switching of the switching valve 27.

  Therefore, the switching valve 27 is configured to switch between a water supply state in which water from the water supply passage 37 is supplied to the hot water supply passage 28 and a hot water circulation state in which hot water from the hot water return passage 26 is supplied to the hot water supply passage 28. . Further, the hot water disinfection tank 1 is provided with a water level meter 39 and the hot water temperature sensor 33 described above. Therefore, when it is input to the control unit 40 that the water level in the hot water disinfection tank 1 is lower than the set value by the detection of the water level gauge 39, the on-off valve 38 is opened by the output from the control unit 40, and the water replenishment state is established. The switching valve 27 is switched, the pump 29 is operated, the boiler 31 is operated, the in-line heater 30 is operated, and the hot water disinfection tank 1 is controlled to be replenished while heating the water in the collection tank 36. At this time, when the temperature of the hot water in the hot water disinfection tank 1 reaches a desired temperature as detected by the hot water temperature sensor 33, the boiler 29 and the in-line heater 30 are stopped and water in the recovery tank 36 is added. The hot water disinfection tank 1 is supplied without heating. When it is input to the control unit 40 that the water level in the hot water disinfection tank 1 has reached the set value by the detection of the water level meter 39, the on-off valve 38 is closed by the output from the control unit 40, and the boiler 29 and the in-line heater 30 To stop water supply. When the water level in the hot water disinfection tank 1 has reached the set value, if the control unit 40 inputs that the temperature of the hot water in the hot water disinfection tank 1 is lower than desired by the detection of the hot water temperature sensor 33, control is performed. The switching valve 27 is switched to the hot water circulation state by the output from the unit 40, the pump 29 is activated, the boiler 31 is activated, the in-line heater 30 is activated, and the hot water in the hot water disinfection tank 1 is being circulated. Heating and hot water are controlled to a desired temperature (about 60 ° C.).

  In addition, the switching valve 27 is configured to be able to switch to a mixed state in which water from the water supply passage 37 and hot water from the hot water return passage 26 are mixed and supplied to the hot water supply passage 28. Further, in the mixed state, the mixing ratio of the water from the water supply path 37 and the hot water from the hot water return path 26 can be changed and adjusted. Thereby, according to the water level and water temperature in the warm water disinfection tank 1, it can control to a desired water level and water temperature accurately. Further, even when the water level in the hot water disinfection tank 1 reaches the set value, when the hot water in the hot water disinfection tank 1 is contaminated with seeds, water from the water supply channel 37 is supplied into the hot water disinfection tank 1. The dirty hot water can be overflowed from the hot water overflow tub 24 and discharged to the outside. Therefore, when the hot water in the hot water disinfection tank 1 is dirty, the hot water in the hot water disinfection tank 1 is replaced while performing the seed disinfection operation without interrupting the seed disinfection operation and replacing the hot water. The seeds can be continuously disinfected and the work efficiency can be improved.

  According to this configuration, the heat efficiency can be improved and the amount of water used can be reduced. In particular, the water stored in the recovery tank 36 can be used to fill the hot water disinfection tank 1 at the start of the next seed disinfection operation, or can be applied to the hot water disinfection tank 1 as cleaning water when not working. it can.

  In addition to the above, a disinfecting water supply port 41 serving as a water supplying means for supplying new water to the hot water disinfection tank 1 is provided. As described above, the cooling water supply port 18 serving as a water supply means for supplying new water to the cooling tank 10 is provided. The cooling water supply port 18 is automatically opened by a signal from the cooling control unit 43 when the water temperature is higher than a predetermined temperature based on the detection of the cooling water temperature sensor 42 that detects the water temperature in the cooling tank 10. Water supply. Thereby, the water temperature in the cooling tank 10 can be maintained at a desired temperature, and the cooling effect can be enhanced. Since the cooling water supply port 18 is configured to supply water at the end of the seed discharge side (discharge chute 17 side) in the cooling tank 10, the cooling water from the cooling water supply port 18 is supplied to the cooling tank. 10 is sequentially supplied from the discharge-side compartment partitioned by the partition wall 16 in the inside, and the temperature of the discharge-side compartment is lowered so that the seeds are sequentially conveyed to the compartment having a lower water temperature, thereby enhancing the cooling effect. be able to.

  Next, a drying and storage process is demonstrated based on FIG. The seed bag P taken out from the discharge chute 17 of the cooling device B is dehydrated by the dehydrator 51, and then stacked on the net container 46. The net container 46 is drained and sent to the drying device C or the drying chamber 52 in FIG. dry. Next, the net container 46 is sent to the cool room 53 to cool, and then sent to the low temperature storage 53 for storage. According to this configuration, it is possible to continuously dry, cool and store the seed bags P in the net container 46 while stacking them, thereby shortening the work time and increasing the work efficiency.

Next, the drying apparatus C will be described with reference to FIG.
A drying tray 56 is provided on one side of the drying chamber 55, and a blower fan 57 and a budding heater 58 are provided on the other side. A warm air passage 44 is provided at the bottom of the drying chamber 55, and the air heated by the heater 58 is sent via the hot air passage 44 by the blower fan 57 and sent to the drying tray 56.

  In addition, a container sheet 48 is laid on the net container 46 and a large number of seed bags P are stacked, and the net container 46 is placed on the drying tray 56. A duct hood 47 is placed on the upper part of the net container 46, and the lower part of the duct hood 47 and the upper part of the container sheet 48 are hermetically connected by, for example, a fastener 49 to form a simple drying chamber. The upper part of 47 and the blower fan 57 are connected by a circulation passage 45 so that the drying air is circulated.

  Further, the drying cradle 56 is configured such that a drying air passage 56 a that is narrow on the lower side and gradually expands toward the entire lower surface of the upper net container 46 is partitioned by a partition plate 56 b so that the drying air flows from the hot air passage 44 toward the net container 46. Are uniformly fed and the stacked seed bags P are uniformly dried. According to the above configuration, the uniform drying air flows from the lower side to the upper side in the net container 46, and the seed bag P can be uniformly and efficiently dried.

  The cooling water overflow rod 34, that is, the cooling water overflow port, may be provided in the cooling tank 10 at the position of the end of the seed input side (hot water disinfection device A side). Thereby, in the cooling tank 10, the cooling water supply port 18 and the overflow port are arranged at the end portions facing each other, and cooling is performed while efficiently discharging the water whose temperature has been increased by cooling the seeds from the overflow port. Since the water from the water supply port 18 can be efficiently supplied into the cooling tank 10 without overflowing, the seed cooling effect can be enhanced. Further, since the water whose temperature has risen can be efficiently recovered from the overflow port into the recovery tank 36, the temperature of the water supplied from the recovery tank 36 to the hot water supply path 28 via the water supply path 37 is increased, and heating by the heater 30 is performed. The amount can be reduced, the fuel consumption of the boiler 31 can be reduced, and the running cost can be reduced. Moreover, since the partition wall 16 is configured such that the water temperature becomes higher in the section on the seed input side of the cooling tank 10, the water whose temperature has been increased can be efficiently discharged from the overflow port. Furthermore, since the supernatant water that has passed through each section can be recovered from the overflow port, clean water can be reused for hot water.

  In the above description, the seed bucket 2 is sequentially transferred in the single hot water disinfection tank 1 to perform the seed disinfection operation. However, a plurality of hot water disinfection tanks are provided and the seed bucket 2 is transferred to each hot water disinfection tank. It is good also as a structure by which it supplies sequentially and seed disinfection work is performed. For example, it is possible to insert a partition plate at an appropriate position in the front-rear direction of the hot water sterilization tank 1 described above, and to separate the hot water sterilization tank in the previous stroke and the hot water sterilization tank in the subsequent stroke in which hot water does not go back and forth. At this time, if the temperature of the hot water in the hot water disinfection tank in the previous stroke is set low (for example, about 50 ° C.) and the temperature of the hot water in the hot water disinfection tank in the subsequent stroke is set high (for example, about 65 ° C.), Since it can be sterilized with high temperature hot water after habituation with low temperature hot water, the germination rate of the seeds can be reduced and the seed disinfection effect can be enhanced. At this time, since the disinfection in the hot water disinfection tank in the previous stroke is accustomed, the partition plate is provided at the front position so that the disinfection time is relatively short (for example, 2 to 3 minutes). What is necessary is just to set so that the front-back length of the disinfection tank may become shorter than the front-back length of the hot water disinfection tank of the front stroke. In the case where the partition plate is provided, the transfer device 3a is provided at the partition plate so that the seed bucket 2 is supplied from the hot water disinfection tank in the previous stroke to the hot water disinfection tank in the subsequent stroke through the partition plate. What is necessary is just to change suitably to the structure which transfers to the upper side. In addition, since the seeds are habituated in the hot water disinfection tank in the previous stroke, the temperature of the hot water in the hot water disinfection tank in the subsequent stroke can be set higher, so that the integrated temperature can be increased even if the entire disinfection time is the same, and the sterilization effect is enhanced. Can do. Furthermore, since it is sterilized at the temperature of multiple types of hot water sterilization tank in the previous stroke and the hot water sterilization bath in the subsequent stroke, it is surely sterilized at 50 ° C. in the hot water sterilization bath in the previous stroke, and the subsequent stroke. Can be surely sterilized at 60 to 65 ° C. in a hot water disinfection tank.

Using this seed disinfection equipment, for example, asparagus which is another processed product can be boiled for food processing such as boiled water and canned food. In addition, when performing the process (hot water process) which boil asparagus, the temperature of the hot water in the hot water disinfection tank 1 is set to about 100 degreeC. At this time, the seed bucket 2 and the cooling bucket 8 are removed. In addition, since the seed bucket 2 is only mounted and locked on the circulating transfer device 3, it can be easily removed. The cooling bucket 8 can be removed together with the shaft 8a. And the container 70 which accommodates asparagus, and the roller-type container supply conveyor 71 which conveys this container 70 are provided. In addition, this container supply conveyor 71 is provided from the hot water disinfection tank 1 to the cooling tank 10, and becomes a container supply apparatus. The container supply conveyor 71 includes a charging conveyor section 71a that conveys the container 70 from the outside of the hot water sterilization tank 1 to the upper side of the hot water sterilization tank 1, and a hot water sterilization tank in a plan view facing the charging conveyor section 71a. 1, a lifting conveyor part 71b provided at a position overlapping with the lifting conveyor part 71b, a takeover conveyor part 71c extending to the front end position of the rear cooling tank 10 following the lifting conveyor part 71b, and a back and forth descending following the takeover conveyor part 71c A cooling introduction conveyor portion 71d that conveys the container 70 into the cooling tank 10 while being inclined, and a cooling conveyor portion 71e that conveys the container 70 backward in the cooling tank 10 following the cooling introduction conveyor portion 71d, It is provided with a carry-out conveyor section 71f that is inclined backward and forward after the cooling conveyor section 71e and carries the container 70 out of the cooling tank 10. A water receiving container 72 for receiving water falling from the container 70 is provided below the terminal end of the carry-out conveyor 71f. In addition, the raising / lowering conveyor part 71b is a structure which raises / lowers from the upper position of the hot water disinfection tank 1 to the inside of the hot water disinfection tank 1 by the raising / lowering motor, and immerses the container 70 to be placed in the hot water in the hot water disinfection tank 1. The container 70 can be transported to the take-up conveyor 71c connected to the rear end at the uppermost position of the lift. Further, an additive supply device 73 for supplying salt as an additive into the hot water disinfection tank 1 is provided above the hot water disinfection tank 1, and salt is added to the hot water in the hot water disinfection tank 1 by the additive supply device 73. By supplying, the temperature of the hot water is easily raised to about 100 ° C. The supply of the additive is performed at predetermined intervals by a timer, or is performed so as to obtain a desired concentration based on the concentration sensor of the additive in the hot water disinfection tank 1, or the amount of hot water supplied to the hot water disinfection tank 1 Or can be done automatically. The concentration sensor can be provided in the hot water supply path 28.

  Therefore, when the container 70 that contains a large number of asparagus so as to face up and down is placed on the charging conveyor portion 71a outside the hot water disinfection tank 1, the charging conveyor portion 71a conveys the container 70 and moves up and down. 71b. And the raising / lowering conveyor part 71b descend | falls, the container 70 is immersed in warm water, and the hot water process which boiles asparagus is performed. When the processing is finished, the elevating conveyor unit 71b rises to the uppermost position, conveys the container 70 to the takeover conveyor unit 71c, and supplies the container 70 from the takeover conveyor unit 71c to the cooling conveyor unit 71e via the cooling introduction conveyor unit 71d. Then, a treatment (cooling treatment) for cooling the heated asparagus by performing immersion in the cooling water in the cooling bath 10 is performed. When the processing is completed, the container 70 is unloaded from the cooling tank 10 via the unloading conveyor unit 71f.

  In addition, although the cooling tank 10 of FIG. 13 has described the long cooling tank before and behind at the time of seed disinfection, the cooling tank same as the time of seed disinfection or another cooling tank is used for the cooling tank at the time of seed disinfection. It is good also as a cooling tank which added and was constituted long before and after.

  Moreover, when processing asparagus, since only the part of the hot water disinfection tank 1 which becomes the space where the elevating conveyor part 71b moves up and down and the container 70 is supplied is used, hot water can be supplied to only this part. Partition plates can be placed before and after the space. As a result, the amount of hot water required for the treatment can be reduced, and as a result, running costs such as operation of the boiler 29 can be reduced. Further, when the seed is processed when the cooling tank 10 is enlarged for asparagus treatment, a partition plate is inserted for each space in which the cooling bucket 8 of the cooling tank 10 is accommodated, and the cooling bucket 8 is accommodated. If the cooling water is supplied only to the space to be used, the amount of cooling water can be reduced and the running cost can be reduced.

Further, as shown in FIGS. 15 and 16, as a container supply device, a suspended conveying device 74 that suspends and conveys the container 70 may be provided instead of the container supply conveyor 71 described above. The suspension transport device 74 includes a transport rail 75 provided from above the hot water disinfection device A (hot water disinfection tank 1) to above the seed cooling device B (cooling tank 10), and a suspension that moves along the transport rail 75. And lowering and conveying mechanisms 76 and 77. The suspension conveyance mechanisms 76, 77 include a suspension wire 79 that hangs downward from a base 78 that is slidably engaged with the conveyance rail 75, and a container 70 is formed by a suspension hook 80 provided at the tip of the suspension wire 79. Is configured to be suspended. Note that two suspension conveyance mechanisms 76 and 77 are provided on the front and rear sides. The hanging wire 79 is configured to elevate and lower the container 70 by being expanded and contracted by an elevating motor provided on the base 78. Moreover, the cooling tank 10 is the structure which provided the additional cooling tank 10-2 adjacent to the rear side of the existing cooling tank 10-1 at the time of seed disinfection. The existing cooling tank 10-1 is large enough to accommodate four containers, and the additional cooling tank 10-2 is large enough to accommodate six containers. , 10-2 are additionally provided with a plurality (ten in total) of container mounting tables 81 for mounting the container 70 above the air ejection pipe 20. Similarly, a single hot water container mounting table 82 for mounting a single container 70 above the air ejection pipe 19 and the hot water pipe 22 is additionally provided at an appropriate position of the hot water disinfection tank 1. . Further, a pre-treatment receiving base 83 for placing the untreated container 70 is provided on the front side of the hot water disinfection tank 1, and a post-treatment receiving base 84 for placing the processed container 70 is provided on the rear side of the cooling tank 10. Provided.

  The suspension conveyance mechanism 76 on the front side (the hot water sterilization tank 1 side) is a container mounting table on the most front side (the hot water sterilization tank 1 side) of the cooling tank 10 (existing cooling tank 10-1) from the position of the pretreatment tray 83. It is configured to move back and forth along the transport rail 75 between the positions 81-1. The rear side (cooling tank 10 side) suspension transport mechanism 77 is processed from the position of the container mounting table 81-1 on the most front side (hot water disinfection tank 1 side) of the cooling tank 10 (existing cooling tank 10-1). It is configured to move back and forth along the transport rail 75 up to the position of the cradle 84. Therefore, as shown in FIG. 18, first, the container 70 placed on the pre-treatment cradle 83 is hooked on the suspension hook 80 of the suspension transport mechanism 76 on the front side (FIG. 18A), and the suspension wire 79. The container 70 is suspended and is moved to the upper position of the container mounting table 82 in the hot water disinfection tank 1 by the front suspension conveyance mechanism 76 (FIG. 18B), and the suspension wire 79 is extended. The container 70 is lowered and placed on the container mounting table 82 in the hot water disinfection tank 1 (FIG. 18C), and hot water treatment is performed in which the container 70 is immersed in hot water and boiled asparagus. When the hot water treatment is finished, the hanging wire 79 is contracted to hold the container 70 (FIG. 18D), and the cooling tank 10 (existing cooling tank 10-1) is moved by the front-side hanging transfer mechanism 76. The container is moved to a position above the most front (hot water sterilization tank 1 side) container mounting table 81-1, the hanging wire 79 is extended and the container 70 is lowered, and the topmost container mounting table 81-1 of the cooling tank 10 is placed. The container 70 is immersed in cooling water to temporarily cool the asparagus, and is then hooked on the suspension hook 80 of the suspension transport mechanism 77 on the rear side to shorten the suspension wire 79. The container 70 is suspended and is moved to a position above the rearmost container mounting table 81-10 of the cooling tank 10 (additional cooling tank 10-2) by the rear suspension transport mechanism 77, and the suspension wire is moved. 79 stretched The container 70 is lowered and placed on the rearmost side of the container placing table 81-10 of the cooling bath 10, for cooling process of earnest asparagus by immersing the container 70 to the cooling water. Note that the front-side suspended transport mechanism 76 places the container 70 after the hot water treatment on the frontmost container placing table 81-1 of the cooling tank 10 and then the next container 70 on the pre-treatment receiving stand 83. Is moved onto the pre-treatment cradle 83, and the carrying operation is performed in the same manner as described above. When the next container 70 is supplied onto the foremost container mounting table 81-1 of the cooling tank 10 by the front suspension conveyance mechanism 76, the rear suspension conveyance mechanism 77 has already moved the container 70 to the container 70. Is transported to the rearmost container mounting table 81 among the container mounting tables 81 of the cooling tank 10 on which no is mounted, and a full-scale cooling process is performed. That is, the second container 70 after the hot water treatment is transferred from the rear side of the cooling tank 10 (additional cooling tank) to the second container mounting table 81-9. Hereinafter, similarly, the container 70 is transported, but when the container mounting table 81 of the cooling tank 10 on which the container 70 is not already mounted is not other than the frontmost container mounting table of the cooling tank 10, the front side suspension is performed. The container 70 transported to the foremost container mounting table 81-1 of the cooling tank 10 by the transport mechanism 76 is subjected to a full-scale cooling process on the container mounting table 81-1 as it is. The container 70 that has been cooled is transported to the post-processing cradle 84 by the rear suspension transport mechanism 77, and the processing is completed.

  The suspension hook 80 is configured to be capable of automatic connection and release of automatic connection such as an electromagnetic type, and the controller can connect the suspension hook 80, extend and retract the suspension wire 79, and move the suspension conveyance mechanisms 76 and 77. It is possible to automatically control according to the processing status of the container. At this time, the rear suspending and transporting mechanism 77 separates the container 70 on the foremost container mounting table 81-1 of the cooling tank 10 into another container mounting table 81 in the cooling tank 10 for full-scale cooling processing. It may be configured such that the work of transporting the container 70 that has undergone the full-scale cooling process to the post-processing cradle 84 is prioritized over the work of transporting to the post.

  According to the above-described suspending and conveying device 74, since it is temporarily cooled at the position in the cooling tank 10 closest to the hot water disinfection tank 1 (the container mounting table 81-1 on the foremost side of the cooling tank 10) immediately after the hot water treatment. Asparagus can be cooled quickly, and processing can be performed uniformly while suppressing variations in processing conditions such as boiled asparagus.

  Further, in order to efficiently boil asparagus, when the container 70 is lowered by the above-described lifting conveyor 71b and the hanging wire 79 and immersed in hot water, the asparagus is first lowered so that only the base portion of the asparagus is immersed in the hot water. The container 70 can be stopped during the processing for a predetermined time, and then the container 70 can be lowered and processed for a predetermined time so that the entire asparagus is immersed in hot water. As a result, it is possible to spend more time on the hard root portion than the upper end portion, so that the entire asparagus can be properly cooked. These processes can be automatically performed by controlling the elevation of the container 70 by the controller. Depending on the size of the asparagus such as L, M, S, etc., the larger the size, the longer is the time required to boil only the root part and the longer the total time required to boil the entire asparagus. It can be configured. At this time, the larger the size, the longer the time required for cooking the root portion than the time required for the entire cooking time, so that the root portion can be reliably processed. Further, in the case of asparagus from which the root portion is removed, a configuration may be adopted in which the container is switched so as not to stop during the descent.

  Moreover, although the capability of the boiler 31 is set so that the temperature of the hot water in the hot water disinfection tank 1 can be raised to 100 ° C for the hot water treatment of asparagus, the seed disinfection work is performed when the seed disinfection work is performed. The hot water disinfection tank 1 may be sterilized by raising the temperature of the hot water in the hot water disinfection tank 1 to 100 ° C. and maintaining it for a certain time before or after the seed disinfection work. This makes it possible to reliably sterilize bacteria that do not die with about 60 ° C. hot water during seed disinfection work, and to prevent the bacteria from being transmitted to the seeds in subsequent work. When the sterilization is completed, the hot water in the hot water disinfection tank 1 is discharged. In sterilization, hot water at 100 ° C. is maintained in the hot water disinfection tank 1 for a certain period of time by heating the boiler 31, and then the boiler 31 is stopped and the hot water is held in the hot water disinfection tank 1 for a certain period of time to be naturally cooled. The hot water may be discharged. Thereby, the bad influence to the drainage equipment by discharging high temperature water as it is can be prevented.

  By the way, the seeds treated by this seed disinfection facility can be sown and nurtured in a seedling raising device 85 as shown in FIGS. 19 and 20, for example. The seedling raising device 85 includes a plurality of seedling pots 86 arranged vertically and horizontally, and a plurality of transport holes (square holes) 88 arranged on the left and right end edges 87 along the longitudinal direction. The plurality of seedling pots 86 are arranged at a predetermined pitch on the left and right sides of the seedling raising device 85 with an interval 89 therebetween. The conveying holes 88 are arranged at the same pitch as the arrangement pitch of the seedling pots 86 in the longitudinal direction of the seedling device 85. Each of the seedling pots 86 is connected to each other at the upper end, has an opening at the top, and has a three-pronged bottom hole 90 serving as a drainage hole at the bottom. By using the bottom hole 90, an extrusion pin or the like can be plunged into the seedling pot 86 from below to take out the seedling in the seedling pot 86.

  The above-mentioned three-pronged bottom hole 90 is in the same direction in each seedling pot 86 on the left and right of the seedling device 85, but the bottom hole 90 is shifted by a predetermined angle for each seedling pot 86 arranged on the left and right. be able to. Accordingly, when the seedlings in the seedling pot 86 for the left and right rows are simultaneously pushed out by the plurality of extrusion pins, the direction in which the resistance when the extrusion pins pass through the bottom hole 90 can be dispersed, so that the nursery device 85 can be prevented from being damaged. .

  Drying and raising the floor of the nursery house, further drying and fertilizing and plowing, irrigating the seed bed, squeezing it, arranging the seedling device 85 seeded with the seed pod on the floor, irrigating the seedling device 85, The seedling device 85 is covered with a film. In this seedling raising method, the seedling device 85 is arranged after the placement bed is crushed, so that when the seedling roots extend to the placement bed, the root elongation can be temporarily stagnated to prevent the initial growth of seedlings. Easily cut roots that stretched to the floor when picking up 85. There is no need to lay a root-cutting net before arranging the seedlings as before, or to step on the seedlings after arranging the seedlings. The work of arranging the containers 85 becomes easy. In addition, in the said fertilization, what is necessary is just to use the conventional fertilizer containing a nitrogen component, a phosphoric acid component, and a potassium component, and what is necessary is just to fertilize 30-50g per 1 tsubo. Moreover, if the water content of the bed is set to 30-60% and the clay content of the bed is set to 10-30% before squeezing by irrigation, the soil surface can be hardened easily and the soil can be kept softer than the soil surface. It is possible to grow seedlings well by properly extending the roots on the floor. Moreover, if the organic substance contains 10% or more of the soil in a volume ratio from the soil surface of the floor before the suppression to 10 cm depth, the soil surface can be easily solidified, and the soil can be kept somewhat softer than the soil surface. . In addition, the pH of the placing bed is 4.5 to 5.5, and the electrical conductivity EC (fertilizer concentration) is 0.2 to 0.8 mS / cm, which prevents seedling blight and does not require additional fertilization. If the placement floor is suppressed at a pressure of 500 to 1500 kg per square meter, when the seedling device 85 is arranged, it becomes difficult for the footprint of the operator to be attached to the placement floor, and the seedling device 85 is easily arranged uniformly. In addition, since the seedling device 85 is covered with a film after irrigating the seedling device 85, drying of the seedling device 85 is prevented and germination is stabilized.

  The irrigation to the seedling device 85 during the raising of the seedling after removing the film is performed by detecting the weight of the sample seedling device 85 with a weight sensor, and starts irrigation when the weight of the seedling device decreases to the irrigation start set value by this weight sensor. If the irrigation increases to the irrigation end set value, the irrigation is stopped. This irrigation control is performed only during the daytime, for example, from 8 o'clock to 15 o'clock. However, if irrigation is performed when the end time of irrigation control is approached, excessive irrigation will occur. Therefore, as shown in FIG. 21, when irrigation is started, if it is close to the end time of irrigation control, the irrigation end set value is corrected to be lower as the time until the end time is shorter. By doing so, excessive irrigation can be prevented, and an appropriate amount of irrigation can be obtained. Conventionally, irrigation was performed until the irrigation end set value was reached regardless of the time.

  As another means, as shown in FIG. 22, when the set time immediately before the end time of irrigation control (for example, 13:00) is reached, the weight of the seedling raising device 85 is set to the irrigation end set value regardless of the irrigation start set value. If irrigation is performed until it reaches the value, and irrigation is not performed thereafter, excessive irrigation can be prevented.

  The irrigation to the seedling device 85 is configured such that the irrigation pipe moves laterally above the seedling device 85 and irrigates the lower seedling device 85 from a plurality of irrigation nozzles provided on the irrigation pipe extending in the horizontal direction. Since the seedling device 85 close to the space where the seedling device 85 is not arranged for the passage in the nursery house and the like is easy to dry, the irrigation nozzles at both ends of the irrigation pipe are set to be larger than other portions so that the amount of irrigation in this portion is increased. It is known to provide many. However, depending on the temperature and humidity environment in the nursery house, on the contrary, an excessive amount of water is irrigated with respect to the nursery device 85 at the end close to the space, and there is a risk of running out of fertilizer. Therefore, as shown in FIGS. 23 and 24, a main irrigation pipe 91 in which irrigation nozzles 92 are arranged at equal intervals and a sub irrigation pipe 93 in which the irrigation nozzles 92 are provided only at both ends are provided side by side. If the irrigation amount in the auxiliary irrigation pipe 93 is adjusted, the irrigation amount to the seedling device at the end can be adjusted appropriately according to the situation. This adjustment can also be performed by switching whether or not the sub-irrigation pipe 93 is irrigated by the reciprocating process when the irrigation pipes 91 and 93 are reciprocated by reciprocating a predetermined area.

  There is also an irrigation apparatus 94 as shown in FIG. This irrigation device 94 is provided with a squirting part 96 that squirts water onto the shower at the tip of the irrigation hose 95, and the operator irrigates the squirting part 96 to the seedling device 85 as appropriate by hand. . Since this irrigation apparatus 94 performs irrigation manually, it is difficult to grasp the irrigation amount, and there is a possibility that the irrigation amount will be excessive or insufficient. Therefore, if the irrigation hose 95 is provided with a flow meter 97 and a notification device 98 that makes a sound notification every time the flow rate reaches a predetermined value is provided, the amount of irrigation can be easily grasped. If it is set as the structure which notifies by quantity, an operator should just irrigate every 4 seedling raising devices 85, whenever it notifies. In place of the notification device 98, an automatic stop valve for automatically stopping irrigation at a predetermined flow rate may be provided, or a notification device for notifying the flow rate every predetermined time may be provided. When the notification timing of the notification device 98 does not match the actual irrigation work and the operator becomes difficult to understand, a reset means (reset button) 99 for resetting the notification timing is provided, and if the operator operates the reset means 99 as appropriate, Good. Moreover, you may use the notification means 98 for the irrigation apparatus provided with the above-mentioned irrigation pipe.

  When raising seedlings in a seedling box, there is a case where a hard seedling box 100 with no flexibility is used at the time of sowing, and after raising to some extent, seedlings are grown in a soft seedling box 101 with low cost and flexibility. When the seedling is transferred to the soft nursery box 101, the seedling tends to collapse, and this transfer is difficult. Therefore, as shown in FIG. 26, a seedling collecting plate 102 is placed in advance in a hard seedling box 100 at the time of sowing, sowing and raising seedlings, and at the time of transfer, the seedling is taken out together with the seedling collecting plate 102 and softened from the seedling collecting plate 102. If the seedling is transferred to the seedling raising box 101, the seedling is not easily broken, and the transfer is facilitated. The seedling plate 102 includes a grip portion 103 that an operator grips and a bottom plate portion 104 on which a seedling is placed, and the upper surface of the bottom plate portion 104 has innumerable drain holes 105 that can grow seedlings, and can be easily transferred. A plurality of ridges 106 are provided. Note that different seedling collecting plates shown in FIG. 28 are provided with gripping portions 103 at both ends, and the upper end of the gripping portion 103 is provided with a convex portion 107 that is pointed upward so that seeds do not rest at the time of sowing.

  FIG. 30 shows a seedling processor 111 provided with a transport rail 108 for transporting a seedling box, a cutting blade 109 for cutting the upper end of a seedling such as a rush, and a root removal brush 110 for removing roots on the bottom surface of the seedling box. It is. The cutting blade 109 and the root removal brush 110 are arranged at positions facing each other up and down across the conveyance rail 108, and act on the top and bottom of the seedling box. Can be done.
