The cultivation control is corrected so as to maximize the quality and yield.

  A technique for generating fine fog with a fine fog generator to cool the inside of the cultivation greenhouse (fine fog cooling) is known, but when the fine fog cooling is performed with the ventilation window 15 and the light-shielding curtain 16 closed, the fine fog suddenly increases. There was a problem that it became an excessively humid state and adversely affected the physiology (growth) of cultivated plants. Therefore, in order to solve the problem, FIG. 5 is a flow chart in the case where fine fog generation is provided for each of the cultivation zones Z1 to Z6 to perform fine fog cooling (or when the entire cultivation greenhouse is finely cooled). When the fine fog cooling by the fine fog generating device is started, the ventilation window 15 is automatically opened and the light-shielding curtain 16 is half opened by the operation (ON) for starting the fine fog cooling device. Later, control is performed so that generation of fine fog by the fine fog cooling device is started. Then, since the fine fog generation by the fine fog cooling device is started after the ventilation window 15 is opened and the light-shielding curtain 16 is in the half-open state, the humidity in the cultivation greenhouse is prevented from suddenly becoming excessively humid. Therefore, without adversely affecting the physiology (growth) of the cultivated plant, appropriate fine fog cooling can be performed, and the temperature in the cultivation greenhouse can be lowered.

Next, the configuration of the cultivation bed 9 will be described in detail.
The cultivation bed 9 has a long shape arranged in the direction perpendicular to the passage 5 in the cultivation zones Z1 to Z6, and the steel plate support frame 31 is arranged on the elevated frame 30 made of pipe material. In addition, the culture medium 32 is placed on the steel plate support frame 31.

  The steel plate support frame 31 has a drainage groove 31a at the bottom, left and right step portions 31b and 31b in the middle, and arcuate surface portions 31c and 31c that are curved outward on the left and right of the upper end. . In addition, a large number of through-holes 31d are provided in the left and right side wall surfaces of the drainage groove 31a so that air can freely enter and exit the drainage groove 31a and the humidity of the groove 31a does not increase. ing.

  An expanded metal (a net-like plate made of strip steel) 33 is placed on the left and right step portions 31b and 31b in the middle, and a hydroponic sheet 34 made of nonwoven fabric is laid on the expanded metal 33 and locked therein. A cultivation medium 32 made of wool is placed.

  And the left and right circular arc surface portions 31c and 31c at the upper end receive the hydroponic sheet 34 provided so as to hang down from the left and right sides of the cultivation medium 32 so that the hydroponic sheet 34 forms a gentle arc-shaped surface. Act on.

  35 is a irrigation pipe made of vinyl disposed on the upper surface of the cultivation medium 32, and has small holes formed at predetermined intervals, and the nutrient solution supply device 17 for the seedlings of the pods planted in two rows on the cultivation medium 32. It is the structure which irrigates the nutrient solution supplied from.

Since the persimmon seedlings are determined in the direction in which the persimmons are formed, when the persimmon seedlings are planted in the culture medium 32, the persimmon seedlings are planted so as to face outward of the cultivation medium 32.
As a result, the strawberries hang down on both the left and right sides of the cultivation medium 32. At this time, the hydroponic sheet 34 is received from below by the left and right circular arc surface portions 31c and 31c of the upper end portion of the steel plate support frame 31, and the hydroponic sheet 34 forms a gentle arc-shaped surface to form the left and right sides of the cultivation medium 32. Since it hangs down on both sides, the stalks that are cocooned are received by this gentle arc-shaped surface, preventing them from being broken or damaged, and the cocoons grow well and produce good quality cocoons. Can be harvested.

  In particular, the steel plate support frame 31 is provided with a groove 31a for drainage, the drainage of the cultivation medium 32 is good, and a large number of through holes 31d are provided on the left and right side wall surfaces of the groove 31a. Since the groove portion 31a has an airy structure that allows air to freely enter and exit and the humidity of the groove portion 31a does not increase, the root of the pod seedling can be prevented from causing root rot, Can be cultivated.

Next, seed disinfection equipment such as seed pods will be described.
The seed disinfection equipment is provided with a hot water disinfection device X, a seed cooling device Y, and a drying device Z in order from the previous process to the subsequent process. The hot water disinfection apparatus X is provided with a box-shaped hot water disinfection tank 101, and a circulating transfer apparatus 103 that circulates and transfers a large number of seed buckets 102 is provided above the hot water disinfection tank 101. The hot water disinfection tank 101 is configured to accommodate 11 seed buckets 102 in a row. Further, the seed bucket 102 is configured to contain a net-like seed bag P for storing seeds for each predetermined amount.

  The circulating transfer device 103 is located on the transfer start end side and lowers the seed bucket 102 that forms a large number of holes and lowers the seed bucket 102 d in the hot water in the hot water disinfection tank 101, and the seed in a state in which the hot water disinfection tank 101 is immersed. A transfer device 103a for transferring the bucket 102, a raising device 103b for raising the seed bucket 102 immersed in the hot water disinfection tank 101 on the transfer end side, and a seed bucket 102 raised by the raising device 103b to the lowering device 103d And a return device 103c.

  The transfer device 103a includes a guide rail portion 104 that receives an edge portion 102a provided at the upper end of the seed bucket 102 from the lower left and right sides, and a transfer-type transfer conveyor 105 for transferring the seed bucket 102 at the transfer start end portion. Provided. The transfer conveyor 105 includes a pressing protrusion 105a that transfers the seed bucket 102 to an appropriate position in the circuit path, and the pressing protrusion 105a moves the fixing shaft 102b in the left-right direction, which is fixed to the left and right of the edge of the seed bucket 102, in the transfer direction. The seed bucket 102 is transferred to the lower side, and the seed bucket 102 on the lower transfer side is sequentially pushed by the seed bucket 102 on the upper transfer side, and the seed bucket 102 is transferred in the hot water disinfection tank 101. Yes.

  The lifting device 103b is provided with left and right chain-type lifting conveyors 106 each having a lifting projection 106a on which the fixed shaft 102b of the seed bucket 102 at the terminal end (transfer terminal) of the guide rail portion 104 is hooked. Accordingly, the driving shaft 106 lifts the fixed shaft 102b of the seed bucket 102 at the end (transfer end) of the guide rail portion 104 to the lifting projection 106a, and the seed bucket 102 is raised. The ascending conveyor 106 is triangular in a side view provided with an oblique movement path (circulation path) that moves in the transfer direction of the transfer device 103a as the seed bucket 102 is lifted from the rising start position where the lifting protrusion 106a is caught by the fixing shaft 102b. It goes around with the round path of the shape. Further, reversing cams 107 for reversing the seed bucket 102 in the middle of the oblique movement path are provided on the left and right, and when the seed bucket 102 is lifted, the reversing cam 107 is one of the fixed shafts 102b on the edge 102a of the seed bucket 102. The upper side of the seed bucket 102 is directed to the seed cooling device Y side with the fixed shaft 102b as a fulcrum by pressing down on the side (the transfer direction side of the transfer device 103a, the seed cooling device Y side) from above. The seed bag P in the seed bucket 102 is discharged to the cooling bucket 108 of the seed cooling device Y. Further, a guide plate 109 is provided to guide the hot water dripping from the seed bucket 102 rising or reversing from the upper end of the hot water disinfection tank 101 to the position of the reversing cam 107 to the hot water disinfection tank 101. By this guide plate 109, the hot water dripping from the seed bucket 102 is returned to the hot water disinfection tank 101 to suppress the release of heat in the hot water disinfection tank 101, and the hot water dripping into the cooling tank 110 of the seed cooling device Y. Decrease in cooling efficiency can be prevented.

  The return device 103c and the lowering device 103d are configured so as to include a chain-type return conveyor 111 provided on the right and left with a conveying protrusion 111a on which the fixing shaft 102b of the seed bucket 102 is hooked. The conveying protrusions 111a are arranged opposite to the front and rear in the circumferential direction of the return conveyor 111, and are configured to hold the fixing shaft 102b between the front and rear protrusions 111a. Accordingly, the seed bucket 102 that has been raised to the upper end of the lifting conveyor 106 of the lifting device 103b is moved down to the transfer start end side of the transfer device 103a after the return conveyor 111 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 102 is positioned above the hot water disinfection tank 101, and an operator supplies the seed bag P to the seed bucket 102. When the transfer device 103a is actuated to create a space for accommodating the seed bucket 102 at the transfer start end, the return conveyor 111 is actuated to lower the seed bucket 102 at the seed bag supply position r, and the seed bucket 102 is The hot water disinfection tank 101 is dropped from the lower end of the return conveyor 111 and supplied. Note that the seed bucket 102 waiting at the seed bag supply position r is inclined such that the lower front side comes into contact with the guide 112 attached to the hot water disinfection tank 101 and the upper opening portion faces the front side. Thereby, an operator can supply seeds (seed bags P) to the seed bucket 102 easily. Furthermore, since the seed bucket 102 is tilted, the seed bucket 102 can be set to a height at which the seed bucket 102 is not immersed in the hot water of the hot water disinfection tank 101 and the height of the opening of the seed bucket 102 can be set as low as possible. It is easy to supply seeds (seed bags P) to the bucket 102.

  Further, when the seed bucket 102 at the seed bag supply position r is lowered and dropped from the lower end of the return conveyor 111 to the hot water disinfection tank 101, noise is generated due to the edge portion 102a of the seed bucket 102 colliding with the guide rail portion 104. There is a possibility that the edge 102a is deformed due to the occurrence or impact. Therefore, a bulge raised on a part of the bottom surface of the hot water disinfection tank 101 so that the bottom of the seed bucket 102 contacts the bottom surface of the hot water disinfection tank 101 before the edge 102a of the seed bucket 102 collides with the guide rail section 104. If the bottom part of the seed bucket 102 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 part 102a is prevented from being deformed and circulated and transferred. The transfer of the seed bucket 102 by the apparatus 103 can be optimized.

  The transfer device 103a intermittently transfers a plurality of seed buckets 102 simultaneously, whereas the return device 103c and the lowering device 103d continuously transfer the single seed bucket 102 to the seed bag supply position r. It is the composition to do. Therefore, the transfer speed of the return device 103c and the lowering device 103d is set to be higher than the transfer speed of the transfer device 103a. By reducing the number of empty seed buckets 102, the cost can be reduced and the temperature of the hot water disinfection tank 101 can be increased. Since the number of empty seed buckets 102 is small, the empty seed buckets 102 are less likely to get in the way when an operator visually recognizes the disinfection status and operation status in the hot water disinfection tank 101.

  In addition, the transfer of the seed bucket 102 that is intermittently transferred by the transfer device 103a is set so that the time in the transfer stop state is longer than the time during the transfer. Therefore, the seed bucket 102 can be retained for a long time above the hot water spout 113 described later in the hot water disinfection tank 101, and the sterilizing effect of the seed can be enhanced. In addition, by increasing the transfer stop time of the transfer device 103a, the stop time of the ascending device 103b and the descending device 103d can be set longer so that the seed bucket 102 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 102 that is stopped. Further, the transfer stop time of the transfer device 103a can be changed by adjusting means, and the total time that the same seed bucket 102 is immersed in the hot water disinfection tank 101 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, it is possible to easily change the immersion time without changing the transfer speed during transfer of the transfer device 103a. The transfer device 103a, the lifting device 103b, the return device 103c, and the lowering device 103d 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 103a 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 101, hot water spouts 113 are arranged at predetermined intervals, and the hot water spout 113 is positioned below the stop position of the seed bucket 102 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 102 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 101 is configured to be inclined downward toward the middle part in the front-rear direction, and a drain groove 114 is formed in the middle part.

  A seed cooling device Y is provided via a supply chute 115 in the subsequent process of the hot water disinfection tank 101. In the seed cooling device Y, a seed cooling tank 110 that is long in the front-rear direction is provided on the rear side of the supply chute 115, and the seed cooling tank 110 is provided with a plurality of cooling buckets 108 from the front side to the rear side. The cooling bucket 108 has a large number of holes and is supported by a horizontal axis 108a so as to be pivotable in the horizontal axis. When the cooling bucket 108 rotates and reverses about the shaft 108a, the seed bag P stored in the cooling bucket 108 is stored in the next cooling bucket 108. Note that the cooling bucket 108 is rotated by a small angle twice when reversed, so that the seed bag P is reliably discharged. A partition wall 116 for partitioning the inside of the tank is provided in each cooling bucket 108 in the cooling tank 110, and the partition wall 116 is higher on the seed discharge side (discharge chute 117 side). The cooling water supply port 118 for supplying new water to the cooling tank 110 is configured to supply water at the end position on the seed discharge side (discharge chute 117 side) in the seed cooling tank 110. The cooling water from the water supply port 118 is sequentially supplied from the discharge side section partitioned by the partition wall 116 in the cooling tank 110.

  If the sensor detects that the seed bucket 102 has been lifted by the lifting device 103b and has arrived immediately before being reversed by the reversing cam 107, the cooling bucket 108 closest to the hot water disinfection device X is reversed and then returned to its original state. The seed bucket 102 rises and is reversed by the reversing cam 107. Thereby, the seed of the cooling bucket 108 can be supplied to the next cooling bucket 108 immediately before the seed is supplied from the seed bucket 102 to the cooling bucket 108, and the cooling time of the seed by the cooling bucket 108 can be extended. The cooling effect can be enhanced.

  The volume of the cooling bucket 108 is set larger than the volume of the seed bucket 102. Therefore, since the volume of the seed bucket 102 is small, it is possible to efficiently use hot water by reducing unnecessary portions in the hot water disinfection tank 101 where the seed bucket 102 is not supplied. Moreover, since the volume of the cooling bucket 108 is large, stirring of seeds is facilitated by air from an air outlet 119 described later, and the cooling effect is enhanced.

  In addition, an air ejection pipe 120 is provided below the cooling bucket 108 of the cooling tank 110, and air is supplied to the air ejection port 119 by the blower 121, and the air is ejected toward the cooling bucket 108 being immersed. Yes.

  Further, the hot water disinfection tank 101 is also provided with an air jet pipe 120, and the air jet pipe 120 is arranged to intersect (orthogonal) in a plan view above the hot water pipe 122 provided with the hot water jet outlet 113. . The hot water pipe 122 extends in the longitudinal direction (front-rear direction) of the hot water sterilization tank 101, and the hot water outlet 113 ejects hot water to the left and right, so that the convection in the short direction (left-right direction) of the hot water sterilization tank 101 It is generated uniformly over the entire area, and the temperature unevenness in the hot water disinfection tank 101 can be suppressed. The air ejection pipe 120 is located below the various child buckets 102 to be stopped, and all seeds can be evenly stirred by ejecting air from the air ejection ports 119 toward the various child buckets 102. As another embodiment, an air outlet 119 is provided immediately below the seed bucket 102, and air is blown out from directly below to stir the seed in the seed bucket 102 and the side below the seed bucket 102. When the air outlet 119 is provided at the position and the air outlet 119 for agitating the seeds in the seed bucket 102 by jetting air from the side position below the seed bucket 102 is provided, the seeds in the seed bucket 102 are moved downward. By receiving the air blown from different directions, the seeds are stirred more reliably and the hot water disinfection of the seeds can be performed more appropriately.

  The blower 121 is common to the cooling bath 110 and the hot water disinfection bath 101, and a long contact tube 123 is provided before and after contacting the air ejection pipe 120 of the hot water disinfection bath 101 on the outer surface (side surface) of the hot water disinfection bath 101. Air is supplied through With this contact tube 123, the temperature of the air supplied to the hot water disinfection tank 101 can be raised, and the temperature drop in the hot water disinfection tank 101 is prevented.

Next, the seed disinfection process will be described.
A net-like seed bag P containing seeds is supplied to a seed bucket 102 stopped at a seed bag supply position r in the middle of the lowering device 103d. Then, the seed bucket 102 is lowered by the lowering device 103d from the seed bag supply position r into the hot water disinfection tank 101 and immersed in the hot water.

  In the hot water disinfection tank 101, the seed bucket 102 is transferred by the transfer device 103a, and the transfer device 103a is intermittently driven. The seed bucket 102 stops at a position facing the hot water outlet 113 and is exposed to the hot water jetted in the stopped state, thereby promoting the disinfection action of the seeds in the seed bag P.

  The seed bucket 102 transferred while stopping for a set time for each hot water outlet 113 is pulled up by the lifting device 103b on the transfer end side. Then, the seed bucket 102 is reversed by the reversing cam 107 in the middle of the ascent device 103b, the seed bag P in the seed bucket 102 is discharged, passes through the supply chute 115, and enters the cooling bucket 108 on the start end side of the cooling tank 110. Supplied.

  The emptied seed bucket 102 is continuously transferred upward by the ascending device 103b, then intermittently transferred above the hot water disinfection tank 101 toward the transfer start end side by the returning device 103c, and again supplied by the descending device 103d to the seed bag. Circulated and transferred to position r.

The circulating transfer device 103 may be configured to continuously drive at a low speed instead of intermittent driving.
The seed bag P supplied to the cooling bucket 108 of the cooling tank 110 is cooled by cooling water. The cooling bucket 108 is configured to be interlocked with the intermittent drive of the circulating transfer device 103, and is rotated and reversed before the next seed bag P is supplied from the hot water disinfection tank 101 to the seed cooling tank 110, and the seed is transferred to the next cooling bucket 108. The bag P is supplied and the seed bag P from the hot water disinfection tank 101 is received. That is, the seed bag P is sequentially transferred from the cooling bucket 108 on the cooling end side to the next cooling bucket 108 by rotating and reversing in turn with the drive motor 161, and from the hot water disinfection tank 101 to the cooling bucket 108 on the cooling start end side. The seed bag P is accepted.

And the seed bag P which passed the several cooling bucket 108 sequentially is discharged | emitted from the discharge chute 117, and is dried with the drying apparatus Z of the next process.
According to this seed disinfection device, hot water disinfection can be performed continuously and efficiently while transferring a plurality of seed buckets 102 by a hot water disinfection tank 101 which is long in the front and back, and seeds are transferred from the hot water disinfection device X to the seed cooling device Y. The bag P can be supplied easily.

  In addition, since the circulating transfer device 103 is intermittently driven every set time, the time for one seed bucket 102 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 108 and the circulation transfer device 103 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 113 at every set interval throughout the hot water disinfection tank 101, temperature unevenness in the hot water disinfection tank 101 is prevented, and the seeds of the seed bag P in the seed bucket 102 are infiltrated with hot water. It can equalize and enhance the hot water sterilization effect. In addition, by intermittently transferring the seed bucket 102 in the hot water disinfection tank 101, seed immersion and water separation are quickened, the immersion sterilization time is accurate, and the sterilization effect can be enhanced. That is, in this embodiment, one seed bucket 102 is stopped and immersed above every 10 hot water jets 113.

Moreover, by ejecting air into the cooling tank 110, the temperature rise of the cooling water in the cooling tank 110 can be prevented from being reduced, and the cooling effect can be increased.
Further, since the cooling bucket 108 is driven and reversed every predetermined time and the seed bag P is transferred while being cooled in the cooling water for a predetermined time, the cooling effect can be enhanced.

Next, the hot water and cooling water supply paths used for the hot water disinfection tank 101 and the cooling tank 110 will be described with reference to FIG.
A hot water overflow tub 124 is provided in the hot water sterilization tank 101, and the hot water overflowed to the hot water overflow tub 124 is discharged to the outside. Further, a hot water discharge port 125 different from the hot water overflow tub 124 is provided in the hot water disinfection tank 101, and the hot water discharge port 125 is supplied to the switching valve 127 through a hot water return path 126 serving as a return path. Accordingly, the hot water discharge port 125 is switched to a state where hot water is discharged by switching the switching valve 127.

  Then, hot water from the hot water return path 126 is supplied to a hot water supply path 128 serving as a hot water supply path via a switching valve 127. The hot water supply path 128 is provided with a pump 129 and an in-line heater 130 serving as a heater. The in-line heater 130 is configured such that steam is supplied from the boiler 131 through a steam supply path 132 having various valves to obtain heat. Hot water is supplied from the hot water outlet 113 to the hot water disinfection tank 101 through the hot water supply path 128. The temperature of the hot water in the hot water disinfection tank 101 is controlled to be about 60 ° C. by the hot water temperature sensor 133.

  In addition, the cooling water overflowed from the cooling tank 110 is returned to the recovery tank 136 via a cooling water overflow trough 134 and a reflux path 135 serving as a cooling water overflow path. The cooling water in the collection tank 136 is supplied to a water supply path 137 serving as a water supply path. The water supply path 137 includes an on-off valve 138 and supplies water to the switching valve 127. And it is the structure which supplies the water of the water supply path 137 to the hot water supply path 128 by switching of the switching valve 127.

  Therefore, the switching valve 127 is configured to switch between a water supply state in which water from the water supply passage 137 is supplied to the hot water supply passage 128 and a hot water circulation state in which hot water from the hot water return passage 126 is supplied to the hot water supply passage 128. . Further, the hot water disinfection tank 101 is provided with a water level meter 139 and the hot water temperature sensor 133 described above. Therefore, when it is input to the control unit 140 that the water level in the hot water disinfection tank 101 is lower than the set value by the detection of the water level gauge 139, the on-off valve 138 is opened by the output from the control unit 140, and the water replenishment state is set. The switching valve 127 is switched, the pump 129 is activated, the boiler 131 is activated, the in-line heater 130 is activated, and the hot water disinfection tank 101 is replenished while heating the water in the collection tank 136. At this time, if the temperature of the hot water in the hot water disinfection tank 101 reaches a desired temperature as detected by the water temperature sensor 133 for hot water, the boiler 131 and the in-line heater 130 are stopped and water in the recovery tank 136 is added. The hot water disinfection tank 101 is supplied without heating. When it is input to the control unit 140 that the water level in the hot water disinfection tank 101 has reached the set value by detection of the water level gauge 139, the on-off valve 138 is closed by the output from the control unit 140, and the boiler 131 and the in-line heater 130 To stop water supply. When the water level in the hot water disinfection tank 101 has reached the set value, if the control unit 140 inputs that the temperature of the hot water in the hot water disinfection tank 101 is lower than desired by the detection of the hot water temperature sensor 133. The switching valve 127 is switched to the hot water circulation state by the output from the section 140, the pump 129 is operated, the boiler 131 is operated, the in-line heater 130 is operated, and the hot water in the hot water disinfection tank 101 is circulated. Heating and hot water are controlled to a desired temperature (about 60 ° C.).

  The switching valve 127 is configured to be able to switch to a mixed state in which water from the water supply passage 137 and hot water from the hot water return passage 126 are mixed and supplied to the hot water supply passage 128. Further, in the mixed state, the mixing ratio of the water from the water supply path 137 and the hot water from the hot water return path 126 can be changed and adjusted. Thereby, according to the water level and water temperature in the warm water disinfection tank 101, it can control to a desired water level and water temperature accurately. Further, even when the water level in the hot water disinfection tank 101 reaches the set value, when the hot water in the hot water disinfection tank 101 is contaminated with seeds, water from the water supply path 137 is supplied into the hot water disinfection tank 101. The dirty hot water can be overflowed from the hot water overflow trough 124 and discharged to the outside. Therefore, when the hot water in the hot water disinfection tank 101 is dirty, the hot water in the hot water disinfection tank 101 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 136 can be used to fill the hot water disinfection tank 101 at the start of the next seed disinfection operation, or can be applied to the hot water disinfection tank 101 as cleaning water when not working. it can.

  In addition to the above, a disinfection water supply port 141 serving as a water supply means for supplying new water to the hot water disinfection tank 101 is provided. Further, as described above, the cooling water supply port 118 serving as a water supply unit for supplying new water to the cooling tank 110 is provided. The cooling water supply port 118 is automatically opened by a signal from the cooling control unit 143 when the water temperature is higher than a predetermined temperature based on the detection of the cooling water temperature sensor 142 that detects the water temperature in the cooling tank 110. Water supply. Thereby, the water temperature in the cooling tank 110 can be maintained at a desired temperature, and the cooling effect can be enhanced. Since the cooling water supply port 118 is configured to supply water at the end of the seed discharge side (discharge chute 117 side) in the cooling tank 110, the cooling water from the cooling water supply port 118 is supplied to the cooling tank. 110 is supplied sequentially from the discharge side compartments partitioned by the partition wall 116, and the temperature of the discharge side compartments is lowered so that the seeds are sequentially conveyed to the compartments having a lower water temperature, thereby enhancing the cooling effect. be able to.

Here, another embodiment of the cooling water supply means of the cooling tank 110 will be described.
When this hot water disinfection equipment is used in a cold district, the tap water is in a very cold state (1 to 5 ° C.), so when the tap water is used as cooling water in the cooling tank 110, the temperature of the cooling water is very low. Become. Then, when the seeds that have been disinfected in the hot water disinfection tank 101 are put on this very cold cooling water, the seeds are rapidly cooled and subjected to stress, which may reduce the germination rate.

  Therefore, a part of the hot water from the hot water supply path 128 heated by the in-line heater 130, which is the circulating hot water in the hot water disinfection tank 101, is supplied to the cooling water supply port 118 to which tap water is supplied via the control valve. If the control valve is controlled so that the water temperature in the cooling bath 110 is maintained at 10 to 18 ° C. by providing a temperature sensor in the cooling bath 110 and having a configuration in which tap water and hot water are placed in 110, The cooling water is kept at an appropriate temperature, so that appropriate seed cooling can be performed, and it is possible to avoid a decrease in germination rate as described above.

  On the other hand, when this hot water disinfection facility is used in a warm region, the cooling water in the cooling tank 110 rises to an appropriate temperature or more, and appropriate seed cooling cannot be performed, causing hot water failure and reducing the germination rate.

  FIG. 17 shows an example in which a cooling device (chiller) 170 is used. In this example, the cooling device 170 is connected to the divided final tank 110-4 of the cooling tank 110, and the water in the final tank 110-4 is cooled to an appropriate temperature to maintain the water temperature. 1-110-3 is configured such that water is introduced from the cooling water supply port 118 and the water is successively overflowed.

  With such a configuration, the seed sterilized in the hot water disinfection tank 101 is first cooled in the previous three tanks 110-1 to 110-3 where water enters from the cooling water supply port 118 and sequentially overflows, and finally, Further, the cooling can be reliably performed in the final tank 110-4 containing the cooling water maintained at an appropriate temperature by the cooling device 170. Therefore, it is possible to appropriately avoid the reduction of the germination rate as described above. Further, since the cooling device 170 does not cool the water in the entire cooling tank 110 but only the water in the final tank 110-4, a small cooling device may be used, resulting in an inexpensive equipment configuration. However, it can be appropriately handled with a small cooling device, so it becomes an environment-friendly facility.

FIG. 18 is a diagram showing the operation timing of the seed bucket 102 in the hot water disinfection tank 101 and the operation timing of the cooling bucket 108 of the cooling tank 110.
That is, FIG. 18A shows that the operation timing of the seed bucket 102 in the hot water disinfection tank 101 and the operation timing of the cooling bucket 108 in the cooling tank 110 coincide, and the seed bucket 102 in the hot water disinfection tank 101 matches. In the above hot water disinfection equipment, there are 10 stop positions of the seed bucket 102 in the hot water disinfection tank 101, and 10 minutes of hot water disinfection can be performed. Are sequentially transferred to the cooling bucket 108 of the cooling tank 110 to be cooled and sterilized. The glutinous rice can be properly sterilized by performing hot water sterilization for 10 minutes at this operation timing.

  On the other hand, since glutinous rice has an appropriate hot water disinfection time of 5 minutes, the operation timing shown in FIG. 18B is set, and the stop time of the seed bucket 102 in the hot water disinfection tank 101 is set to 30 seconds. In the hot water disinfection equipment described above, there are 10 stop positions of the seed bucket 102 in the hot water disinfection tank 101, and 5 minutes of hot water disinfection can be performed, and after the disinfection is completed, it is sequentially transferred to the cooling bucket 108 of the cooling tank 110, The cooling bucket 108 of the cooling tank 110 is set to a stop time of 1 minute (one operation timing for two movements of the seed bucket 102 in the hot water disinfection tank 101). The glutinous rice can be properly moved to the cooling tank 110 without stagnation, and can be properly sterilized.

  As described above, if the operation timing of the seed bucket 102 in the hot water disinfection tank 101 and the operation timing of the cooling bucket 108 in the cooling tank 110 can be adjusted as appropriate, hot water disinfection work for various seeds becomes possible. Improves.

  The time until the seed bucket 102 at the seed bag supply position r is lowered by operating the return conveyor 111 to drop and supply the seed bucket 102 from the lower end of the return conveyor 111 to the hot water disinfection tank 101 (the seed bucket 102 is If the time until the seed bucket 102 in the hot water disinfection tank 101 is lifted from the hot water by the ascending conveyor 106 (the time until the seed bucket 102 comes out of the hot water) is T2 seconds. When the timing T seconds at which the seed bucket 102 operates from the stop position is set to a value calculated by T = (600 seconds + T1−T2) / 10, the operation timing in FIG. 10 stop positions of the seed bucket 102 can be provided, and hot water disinfection can be accurately set to 10 minutes.
