An embodiment of the present invention will be described below with reference to the drawings.
As shown in the plan view of FIG. 1 and the side view of FIG. 2, the hot water disinfection facility of the present embodiment has a hot water disinfection device A, a seed cooling device B, and a drying device C in order from the previous step to the subsequent step (see FIG. 13). Are provided sequentially. 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.

  3 is a side view showing a part of the transfer device and the lowering device, FIG. 4 is a side view showing a part of the lifting device, and FIG. 5 is a part of the lifting device and a part of the return device. 6 is a side view showing a seed bag supply position, and FIG. 7 is a side view showing a reversing cam (reversing device) and a guide plate.

  The circulating transfer device 3 has a lowering device 3d that lowers the seed bucket 2 that forms a large number of holes on the transfer start end side and immerses 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 (FIG. 4) provided with lifting projections 6a on which the fixing shaft 2b of the seed bucket 2 at the end (transfer end) of the guide rail portion 4 is hooked. 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 being inherited by the return conveyor 11, and then is lowered to be in the middle of the lowering path. It waits at the seed bag supply position r (FIG. 6). 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 comes into contact with the guide 12 attached to the hot water disinfection tank 1 and the upper opening portion faces the front side (seed input 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, soaked glutinous rice seeds are soaked for 6 minutes, etc.). 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 ejected toward the surface, 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.

  Here, 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) portion in the hot water disinfection tank 1 can be increased, and the hot water is supplied from the seed bucket 2. When seeds are introduced into the sterilization tank 1, it is possible to suppress a decrease in the temperature of the hot water around the charging part, and the temperature of the hot water in the hot water sterilization 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. FIG. 8 shows a sectional side view of the cooling tank 10, FIG. 9 shows a plan view of the cooling tank 10, and FIG. 10 shows a supply path diagram of hot water and cooling water.

  The cooling bucket 8 forms a large number of holes and is supported by a horizontal axis 8x so that the horizontal axis can rotate. Then, when the cooling bucket 8 is rotated and reversed about the shaft 8x (FIG. 2), the seed bag P accommodated in the cooling bucket 8 is accommodated in the next cooling bucket 8. Therefore, the cooling transfer device is constituted by the cooling bucket 8 and the shaft 8x. Note that the cooling bucket 8 is rotated by a small angle twice when reversing so as to reliably discharge the seed bag P. 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.

  Further, 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.

  As shown in FIG. 11, when processing a large amount of seeds such as seed pods, the cooling tank 10 is provided with an odd number of cooling buckets 8 partitioned by the partition walls 16 as a whole, and a belt 63 (cooling bucket driving device). (1st, 263a, 63b) and cooling bucket drive device 64 (first and second cooling bucket drive devices 64a, 64b) are configured in two stations, and the discharge side is provided one more than the input side, In the case of increasing the amount of seeds to be treated, even if the number of buckets 8 is not increased, if the work is performed according to the procedure described below, a sufficient seed cooling time can be secured.

  That is, in the stage shown in the uppermost stage of FIG. 11 (FIG. 11A), the first cooling bucket drive device 64a for driving the three cooling buckets 8 by the first belt 63a is provided on the input side, and the four cooling buckets 8 are provided. The second cooling bucket drive device 64b for driving the second belt 63b is provided on the discharge side.

  As shown in FIG. 11, when the two cooling bucket drive devices 64a and 64b are driven simultaneously, the last cooling buckets 8c and 8g driven by the drive devices 64a and 64b are first driven by the drive devices 64a and 64b, respectively. Then, the seed bags P in the cooling buckets 8c and 8g are transferred to the cooling bucket 8d and the discharge chute 17, respectively (FIG. 11 (b)). Thereafter, the last cooling buckets 8c and 8g are restored.

  At the next timing, as shown in FIG. 11C, the cooling buckets 8b and 8f are driven by the driving devices 64a and 64b, respectively, and the seed bags P in the cooling buckets 8b and 8f are moved to the cooling buckets 8c and 8g. As shown in FIG. 11 (d), the driving devices 64a and 64b are driven together at the same timing, so that the cooling buckets 8a and 8e are driven, and the seed bags P in the cooling buckets 8a and 8e are respectively cooled. Moved to 8b and 8f. Next, at the timing shown in FIG. 11 (e), the cooling bucket 8d is driven by the driving device 64b (at this time, the driving device 64a is inactive (the bucket is not driven even if the driving device 64a is driven as another embodiment). The seed bag P in the cooling bucket 8d is moved to the cooling bucket 8e, and then the supply chute 15 into the cooling bucket 8a without the seed bag P as shown in FIG. The seed bag P is supplied from the above, thus solving the following conventional problems.

  It is conceivable that the seed bags P in each cooling bucket 8 are started to be driven at the same time, and the number of cooling buckets 8 can be sufficiently cooled by the processing capacity. Is easy and reliable. However, in order to ensure sufficient seed cooling time, it is necessary to increase the number of cooling buckets 8. However, if the cooling buckets 8 are excessively increased, the driving of the cooling buckets 8 does not end within one cycle. Further, when the operation speed of the cooling bucket 8 is increased, there are problems that discharge errors increase and noise increases, and high-capacity processing cannot be realized.

  Furthermore, 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 relatively small, it is possible to efficiently use hot water by reducing an unnecessary portion 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 (FIG. 10) described later, and the cooling effect is enhanced.

  Further, an air ejection pipe 20 (FIG. 10) is provided below the cooling bucket 8 of the cooling tank 10, and air is supplied to the air ejection pipe 20 by a blower 21, and the air jet is directed toward the cooling bucket 8 being immersed. Air is ejected from the outlet 19. Moreover, the hot water disinfection tank 1 is also provided with an air jet pipe 20 provided with an air jet 19, and this air jet pipe 20 intersects (orthogonal) in plan view above the hot water pipe 22 provided with the hot water jet 13. Are arranged to be. 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, the convection in the short direction (left-right direction) of the hot water disinfection tank 1 is entirely in the front-rear direction. 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 20 is positioned 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 20 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 (FIG. 6) 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 cam 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 empty 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 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 equipment, it is possible to efficiently disinfect the hot water continuously while transferring a plurality of seed buckets 2 by the hot water disinfection tank 1 which is long in the front and back, and the seed is 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 jets 13 (FIG. 2) throughout the hot water disinfection tank 1 at set intervals, temperature unevenness in the hot water disinfection tank 1 is prevented, and the seed bag P in the seed bucket 2 has a seed. Hot water penetrates evenly, and the hot water sterilization effect can be enhanced. 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, the degree of the temperature rise of the cooling water in the cooling tank 10 can be made small by ejecting air in the cooling tank 10, and a cooling effect can be enlarged.
Furthermore, 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. The hot water disinfection tank 1 is provided with a hot water discharge port 25 different from the hot water overflow basin 24, and a hot water return channel 26, a switching valve 27, a pump 29, and a heater serving as a return path from the hot water discharge port 25. The heaters 30 are sequentially provided, and the hot water heated again from the in-line heater 30 returns to the hot water disinfection tank 1.

  On the other hand, the steam from the steam generator (boiler) 31 is supplied from the first steam flow path 32a having the first switching valve 28a to the hot water disinfection tank 1 via the inline heater 30 and the first steam flow path 32a. There is a route that is supplied to the hot water disinfection tank 1 via the second steam flow path 32b having the second switching valve 28b provided at the parallel position.

  When the first switching valve 28a is opened and the second switching valve 28b is closed, the steam from the steam generator (boiler) 31 is heated from the first steam channel 32a via the in-line heater 30 and returned to the hot water. When the hot water is supplied to the hot water disinfection tank 1 via 26, the second switching valve 28b is opened, and the first switching valve 28a is closed, the steam from the steam generator (boiler) 31 is supplied to the second steam flow. The hot water in the hot water disinfection tank 1 can be obtained from the path 32b to the hot water disinfection tank 1 and generate a larger amount of heat than the hot water from the hot water return path 26. In addition, when returning the hot water heated using the in-line heater 30 from the 1st steam flow path 32a to the hot water disinfection tank 1 from the hot water return path 26, the pump 29 is driven.

  Therefore, by switching the first and second switching valves 28a, 28b, the temperature of hot water is adjusted from the hot water discharge port 25 by the in-line heater 30 and then returned to the hot water disinfection tank 1, and new water vapor from the boiler 31 is used. Can be switched to supplying hot water to the hot water disinfection tank 1.

  The conditions for using the heater 30 and / or the boiler 31 as a heating source can be selected as appropriate according to the crop. The parts to which the switching valves 28a and 28b shown in FIG. Can be attached to hot water supply piping.

  In addition, when using a temperature raising method in which raw steam is directly supplied into the hot water of the hot water disinfection tank 1 at the time of sowing treatment, the processing temperature varies greatly, and uniform treatment cannot be performed. It is desirable to supply to the disinfection tank 1.

  In order to prevent clogging of the circulating hot water discharge port 25 of the hot water disinfection tank 1, the seed bucket 2 shown in the perspective view of FIG. 12 and a cleaning brush 69 are provided on the side surface of the bucket 2. . Thus, clogging of the hot water discharge port 25 can be prevented, and the occurrence of uneven temperature and poor disinfection of the hot water can be prevented.

  Although not shown, the water overflowed from the cooling bath 10 can be used as circulating water in the hot water bath 1 by warming the cold water through the overwater piping 67 (FIG. 10) coming out of the hot water bath 1.

  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 return path 26 by the switching of the switching valve 27.

  Accordingly, the switching valve 27 is configured to switch between a water replenishment state in which water from the water supply passage 37 is supplied to the hot water return passage 26 and a hot water circulation state in which hot water from the hot water discharge port 25 is supplied to the hot water return passage 26. ing. In addition, the hot water disinfection tank 1 is provided with a water level meter 39 and a hot water temperature sensor 33.

  Accordingly, when the control unit 40 inputs 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 and the in-line heater 30 are operated, and if necessary, the boiler 31 is operated to replenish the hot water disinfection tank 1 while heating the water in the recovery tank 36. It is controlled as follows.

  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, the inline heater 30 and the boiler 31 are stopped, and the inside of the recovery tank 36 is stopped. Water is supplied to the hot water disinfection tank 1 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 as detected by the water level gauge 39, the on-off valve 38 is closed by the output from the control unit 40, and the boiler 31 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 and the in-line heater 30 are operated, and the boiler 31 is operated as necessary, so that the hot water in the hot water disinfection tank 1 is discharged. Heating while circulating is controlled so that the hot water reaches a desired temperature (about 60 ° C.).

The temperature of the hot water in the hot water disinfection tank 1 is controlled to be about 60 ° C. in the case of seeds and about 100 ° C. in the case of asparagus described later.
The switching valve 27 mixes water from the water supply passage 37 and hot water from the hot water return passage 26 and supplies the hot water to the hot water return passage 26 having a pump 29, and the mixture of water and hot water is supplied to the hot water disinfection tank 1. It can be supplied. Further, in the mixed state of water and hot water, the mixing ratio of water from the water supply passage 37 and hot water from the hot water return passage 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, it is possible to improve thermal efficiency and reduce the amount of water used. 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 supply 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.

  Moreover, 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 (such as FIG. 2) is dehydrated by the dehydrator 51, then stacked on the net container 46, and the net container 46 is drained, and then the drying apparatus of FIG. It sends to the drying room 52 of C, and dries. Next, the net container 46 is sent into the cool room 53 to cool, and sent to the low temperature storage 54 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 52, 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 52, 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, and is dried from the hot air passage 44 toward the net container 46. The wind is uniformly fed so that the stacked seed bags P are evenly 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 34a, may be provided in the cooling tank 10 at the position of the end portion on 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 34a will be arrange | positioned in the edge part which mutually opposes, While draining the water which raised the temperature by cooling a seed from the overflow port 34a efficiently. Since the water from the cooling 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 collected in the recovery tank 36 from the overflow port 34a, the temperature of the water supplied from the recovery tank 36 via the water supply path 37 to the hot water return path 26 is increased. Therefore, 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 sterilization tank 1 to perform the seed sterilization operation. However, a plurality of hot water sterilization tanks are provided so that the seed bucket 2 is sent to each hot water sterilization tank. It is good also as a structure by which it supplies sequentially and seed disinfection work is performed. For example, a partition plate (not shown) may be inserted at an appropriate position in the front-rear direction of the hot water disinfection tank 1 described above, and separated into a hot water disinfection tank in the previous stroke and a hot water disinfection bath in the subsequent stroke in which hot water does not come and go. it can. At this time, if the temperature of the hot water in the hot water disinfection tank 1 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 1 in the subsequent stroke is set high (for example, about 65 ° C.), Since the seeds can be conditioned with hot water at a low temperature and then disinfected with a hot water at a high temperature, 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 1 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 hot water disinfection tank 1 may become shorter than the front-back length of the hot water disinfection tank 1 of the front stroke.

  In addition, when the above-mentioned partition plate (not shown) is provided, the transfer device 3a is supplied so that the seed bucket 2 is supplied from the hot water disinfection tank 1 in the previous stroke to the hot water disinfection tank 1 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 by the part of a partition plate. Moreover, since the seeds are habituated in the hot water disinfection tank 1 in the previous stroke, the temperature of the hot water in the hot water disinfection tank 1 in the subsequent stroke can be set higher, and as a result, the integrated temperature can be increased even if the entire disinfection time is the same, and the sterilization effect is improved. Can be increased. Furthermore, since the sterilization is performed at a plurality of types of hot water in the hot water sterilization tank 1 in the previous stroke and the hot water sterilization tank 1 in the subsequent stroke, the bacteria that are likely to die at 50 ° C. are surely sterilized in the hot water sterilization bath 1 in the previous stroke. In the hot water disinfection tank 1 in the subsequent process, bacteria that can easily be killed at 60 to 65 ° C. can be surely sterilized.

  Using this seed disinfection equipment, for example, for food processing such as boiled food and canned food, it is possible to boil crops other than straw such as asparagus, which is another processed product. In addition, as shown in the side view of FIG. 15 and the plan view of FIG. 16, when performing the process of boiling asparagus (hot water treatment), the temperature of the hot water in the hot water disinfection tank 1 is about 100 ° C. Set. At this time, the seed bucket 2 and the cooling bucket 8 are removed. Here, since the seed bucket 2 is only placed and locked on the circulation transfer device 3, it can be easily removed. The cooling bucket 8 can be removed together with the shaft 8x.

  And the container 70 which accommodates asparagus, and the roller-type container supply conveyor 71 which conveys this container 70 are provided. The container supply conveyor 71 is provided from the hot water disinfection tank 1 to the cooling tank 10 and serves as a container supply device. 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 inclines to convey the container 70 into the cooling tank 10, a cooling compare portion 71e that conveys the container 70 backward in the cooling tank 10 following the cooling introduction conveyor portion 71d, and a cooling conveyor It is provided with a carry-out conveyor portion 71f that is inclined backward and forward after the portion 71e and carries the container 70 out of the cooling tank 10.

  A water receiving container 72 that receives 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 a predetermined time by a timer, or the additive is supplied at a desired concentration based on a concentration sensor (not shown) of the additive in the hot water disinfection tank 1, or is supplied to the hot water disinfection tank 1. Or automatically based on the amount of hot water supplied. The concentration sensor can be provided in the hot water return path 26.

  During the processing of crops other than seed sows such as asparagus, the salt in the hot water in the hot water disinfection tank 1 is mixed as described above, so that the deterioration of the filter and the pump 29 is accelerated. For this reason, the filter and pump are prevented from deteriorating by not circulating the hot water in the hot water disinfection tank 1 when processing crops other than the seeds.

  Accordingly, when the container 70 containing a large number of asparagus and the like 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. To the unit 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 moves the container 70 from the takeover conveyor unit 71c to the cooling conveyor unit 71e via the cooling introduction conveyor unit 71d. The process (cooling process) which supplies and is immersed in the cooling water in the cooling tank 10, and cools the heated asparagus is performed. When the processing is completed, the container 70 is unloaded from the cooling tank 10 via the unloading conveyor unit 71f.

  As shown in FIG. 10, when seeds such as seed pods are treated, the first switching valve 28a is opened, the second switching valve 28b is closed, and the temperature is raised and kept by heating with the in-line heater 30, but asparagus other than seeds such as asparagus is used. At the time of crop processing, the first switching valve 28a is closed and the second switching valve 28b is opened, and steam from the boiler 31 is supplied to the hot water disinfection tank 1 to warm and warm the hot water. In addition, water supply at the time of processing crops other than seeds such as asparagus is supplied with hot water whose temperature is increased by using a pump 29 and an in-line heater 30 from the water supply path 37 via the switching valve 27. At this time, the amount of water supplied to the hot water disinfection tank 1 is determined according to the detected value of the water level gauge 39, and the water supply line supplied from the heater 30 is not operated when water supply is unnecessary.

  In this way, crops such as asparagus other than seeds may have a large amount of soil attached in some cases, and if the heater 30 is used in this state, the filter in the hot water disinfection tank 1 is clogged and normal. Since this hinders operation, the water supply line supplied from the heater 30 is not operated when water supply is unnecessary. In addition, since disinfection of crops other than seeds is performed at a high temperature, if cold water is supplied at the time of water supply, the temperature of the water drops, and the operation needs to be interrupted until the temperature is raised. Is supplied to the hot water disinfection tank 1.

  As shown in FIG. 15, the air outlet 19 for supplying air to the hot water disinfection tank 1 is switched between a seed disinfection process and a disinfection process for crops such as asparagus other than seeds. Adjustment of the air jet 19 used and the air jet 19 not used is performed by opening and closing the valves 60a to 60d.

  The range in which the hot water disinfection tank 1 and the cooling tank 10 are used differs between seed treatment and crop treatment other than seeds. Therefore, since there is a lot of loss if all the air jets 19 are always used, for example, the air jets 19 that are opened and closed by the valve 60a in FIG. 15 are exclusively used for seed disinfection, and the air that is opened and closed by the valve 60b. The air outlet 19... That is opened and closed by the valve 60 c is used in combination with seeds and asparagus, and the air outlet 19 that is opened and closed by the valve 60 d is used exclusively for asparagus.

Although not shown, when opening and closing of the individual air outlets 19 is necessary, it is possible to provide valves in the inlet pipes of the air outlets 19 and adjust the opening and closing thereof.
Moreover, although the cooling tank 10 shown in FIG. 15 has described the long cooling tank before and behind different at the time of seed disinfection, it is the same cooling tank at the time of seed disinfection, or another cooling tank at the time of seed disinfection. It is good also as a cooling tank comprised by adding and lengthening back and forth.

  When processing asparagus or the like, since only a part of the hot water disinfection tank 1 that is a space to which the elevating conveyor 71b is moved up and down and the container 70 is supplied is used, the hot water can be supplied only to this part. Partition plates 65 (FIGS. 15 and 16) can be inserted before and after the space. Thereby, the quantity of the hot water required for a process can be reduced, and by extension, running costs, such as a driving | operation of the boiler 31, can be reduced. In addition, when the seed is processed when the cooling tank 10 is enlarged for the asparagus treatment, a partition plate (not shown) for partitioning each space in which the cooling bucket 8 of the cooling tank 10 is accommodated is inserted. If the cooling water is supplied only to the space in which the cooling bucket 8 is accommodated, the amount of the cooling water can be reduced and the running cost can be reduced.

  In order to easily supply the container 70 of crops other than seeds such as asparagus manually to the disinfection facility, driving devices 63 and 64 arranged on the side wall surface of the container 70 in the plan view shown in FIG. Hot water pipes and air pipes arranged on the side wall surface of the disinfection tank 1 are arranged on the same side wall surface of the present disinfection equipment, and the supply area K of the container 70 is arranged in the direction opposite to the side wall surface.

  It is set as the structure which can attach the partition plate 65 for the process of crops other than a seed to the hot water disinfection tank 1 (refer FIG. 15, FIG. 16). The lower part of the partition plate 65 is fixed using the side surface of the drainage groove 66 of the hot water disinfection tank 1, and by installing the partition plate 65, one outlet of the hot water disinfection tank 1 (connected to the drainage groove 66 is connected). ) Can be used for both seeds and non-seed crops. In this way, when processing crops other than seeds, the temperature is high, but since a large volume is not required compared to seeds, water and fuel can be saved without using wasted space. Moreover, drainage piping is simplified by using one drainage port for both seeds and crops other than seeds. By using the side surface of the drain outlet for fixing the lower portion of the partition plate 65, there is no clogging of soil and water, and cleaning becomes easy.

  Further, as shown in FIGS. 17 and 18, respectively, as a side view and a plan view of a seed disinfection facility when processing asparagus, the container supply device shown in the side view of FIG. 15 and the plan view of FIG. Instead of the conveyor 71, a suspended conveying device 74 that suspends and conveys the container 70 may be provided. 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 20 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.

As shown in the schematic side view of the hot water disinfection facility in FIG. 19 and the operation pattern diagram of the suspension conveyance mechanism in FIG. 20, the container 70 is conveyed by the suspension conveyance mechanism 76 in the direction of the arrow.
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.

  Accordingly, as shown in FIG. 20, 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. 20A), and the suspension wire 79. The container 70 is suspended and is moved to a position above the container mounting table 82 in the hot water disinfection tank 1 by the front-side suspension transport mechanism 76 (FIG. 20B), and the suspension wire 79 is extended. The container 70 is lowered and placed on the container placing table 82 in the hot water disinfection tank 1 (FIG. 20 (c)), and the hot water treatment is performed in which the container 70 is immersed in the hot water and the asparagus is boiled. When the hot water treatment is finished, the suspension wire 79 is contracted to hold the container 70 (FIG. 20 (d)), and the cooling tank 10 (existing cooling tank 10-1) is suspended by the front suspension conveyance 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.

  Thereafter, the container 70 is hung by contracting the suspension wire 79 by hooking it on the suspension hook 80 of the rear suspension transport mechanism 77, and the cooling tank 10 (additional cooling tank) is suspended by the rear suspension transport mechanism 77. 10-2) is moved to an upper position of the rearmost container mounting table 81-10, the suspension wire 79 is extended, the container 70 is lowered, and the uppermost container mounting table 81-10 of the cooling tank 10 is moved upward. Then, the container 70 is immersed in cooling water to cool the asparagus in earnest.

  Note that the front-side suspending and transporting mechanism 76 places the container 70 that has been subjected to 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 70. 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 quickly cooled, and it is possible to perform uniform processing while suppressing variations in the processing state 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 the time required for cooking at the root and the time required for 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.

  As shown in FIG. 15, when a cold water supply port 61 is provided near the center of the upstream side surface in the cooling tank 10, and the cold water is ejected from the cold water supply port 61 with a predetermined or higher water pressure, the container 70 is transported. The cooling water flow can be used, and no manual assistance is required when the container 70 is carried into the cooling tank 10.

  By the way, the seeds treated by the seed disinfection facility can be sown and nurtured in a seedling device 85 as shown in a side view of the seedling device 85 in FIG. 21 and a plan view of the seedling device 85 in FIG. 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 roughing the bed in the nursery house, further drying and fertilizing and plowing, irrigating the seed bed, reducing the pressure, arranging the seedling device 85 seeded with the seed pod on the bed, 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, what is necessary is just to use the conventional fertilizer containing a nitrogen component, a phosphoric acid component, and a potassium component in the said fertilization, and should just 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 the timing chart of irrigation control in FIG. 23, when irrigation is started, when it is close to the end time of irrigation control, the irrigation end set value is set as the time is shorter according to the time until the end time. If irrigation is performed with a low correction, excessive irrigation can be prevented and an appropriate irrigation amount 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 the timing chart of the irrigation control of FIG. 24, when the set time (for example, 13:00) immediately before the end time of the irrigation control is reached, regardless of the irrigation start set value, If irrigation is performed until the weight reaches the irrigation end set value, and irrigation is not performed thereafter, excessive irrigation can be prevented.

  Although the irrigation to the seedling device 85 is not shown, the irrigation pipe moves laterally above the seedling device 85 from a plurality of irrigation nozzles provided in the irrigation pipe extending in the horizontal direction in the seedling house, and the lower seedling device However, 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, both ends of the irrigation pipe are increased so that the irrigation amount in this portion increases. It is known to provide more irrigation nozzles than other parts. 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 the side view of FIG. 25 and the plan view of FIG. 26, the main irrigation pipe 91 in which the irrigation nozzles 92 are arranged at equal intervals and the auxiliary irrigation pipe 93 in which the irrigation nozzles 92 are provided only at both ends are provided. If the irrigation amount in the auxiliary irrigation pipe 93 is adjusted as necessary, 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 device 94 as schematically shown in FIG. This irrigation apparatus 94 is provided with a squirting part 96 that squirts water in the form of a shower at the tip of the irrigation hose 95, and the operator irrigates the squirting part 96 appropriately toward the seedling device 85 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 at regular intervals 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. 28, a partial longitudinal sectional view of the seedling boxes 100, 101 is shown, and in FIG. 29, a partial schematic perspective view of the seedling collecting plate 102 is shown. 102, sowing, raising seedlings, taking out the seedlings together with the seedling-removing plate 102 at the time of transfer, and transferring them from the seedling-removing plate 102 to the soft nursery box 101, the seedlings are less likely to collapse and can be easily transferred Become. 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 arranged in parallel along the longitudinal direction of the gripping portion 103 is provided.

  In addition, as shown in FIG. 30 which is a partial schematic perspective view of the seedling plate 102 of another embodiment, different seedling plates are provided with gripping portions 103 at both ends, and seeds are placed on the upper end of the gripping portion 103 at the time of sowing. The convex part 107 pointed upwards is provided so that it may not exist. 31 shows a partial cross-sectional view when the seedling plate 102 of FIG. 30 is placed on the seedling box 100, seeds falling from the seedling convex portion 107 of the seedling plate 102 are transferred from the grip portion 103 to the bottom plate. It is easy to fall to the part 104.

  FIG. 32 shows a seedling treatment including a transport rail 108 that transports the seedling box 101, a cutting blade 109 that cuts the upper end of the seedling such as a rush, and a root removal brush 110 that removes roots on the bottom surface of the seedling box 101. Machine 111. The cutting blade 109 and the root removal brush 110 are arranged at positions facing each other up and down across the transport rail 108 and act on the top and bottom of the seedling box 101. Therefore, it is difficult for extra resistance to be applied to the seedling box 101, and the seedling is properly treated. Processing work can be performed.
