Description

  The present invention relates to an apparatus for disinfecting seeds such as seed pods by immersing them in warm water heated to a predetermined temperature for an appropriate period of time.

  In general, in warm water disinfection of seeds, a method is adopted in which seeds are disinfected by immersing them in warm water heated to a predetermined temperature for an appropriate time, and then cooled by immersing in cold water.

  In this case, the disinfection time by immersion in warm water needs about 10 minutes, whereas the cooling time by immersion in cold water may be about half of the disinfection time, such as about 5 minutes.

Therefore, conventionally, in this disinfection device, for example, as described in Patent Document 1 and the like, two disinfection tanks containing warm water and cold water are placed in a path for transferring a cage containing seeds. Two cooling tanks are arranged side by side along the transfer direction, and the cage containing the seeds is immersed in the first disinfection tank of the two disinfection tanks for about 5 minutes. After being lifted from the disinfecting tank, it is immersed in the second disinfecting tank for about 5 minutes, and then it is lifted from the second disinfecting tank and then immersed in the cooling tank for about 5 minutes. is doing.
JP-A-11-318118

  However, in this conventional disinfection device, the cage containing the seeds is appropriately transferred to the first disinfection tank (approx. Soaked in the first sterilization tank, then moved to the second sterilization tank, and immersed in the second sterilization tank for the appropriate time (about 5 minutes), Next, the second disinfection tank is lifted and then transferred to a cooling tank, and immersed in the cooling tank for the appropriate time (about 5 minutes).

  That is, in the conventional disinfection apparatus, since the time interval of intermittent transfer of the cage containing the seeds is the same as the time of immersion in the cooling tank, the cage can be appropriately transferred to the first disinfection tank. Disinfection work by being configured to obtain a predetermined disinfection time by shifting from the immersion of time (about 5 minutes) to the appropriate time (about 5 minutes) immersion in the second disinfection tank. In the time required for the whole, the cage is transferred from immersion in the first disinfection tank to immersion in the second disinfection tank at the time of hot water disinfection by immersion in each of both disinfection tanks. In other words, the time required for the disinfection work is increased by the time required for the transfer, so that the workability is low and the cost is increased. The entire system is large enough to accommodate the tank. Not only to lead to a reduction, there is a problem that lead to price up.

  This invention makes it a technical subject to provide the disinfection apparatus which eliminated these problems.

In order to achieve this technical problem, the present invention
“A disinfecting tank containing hot water and a cooling tank containing cold water are arranged side by side, and further, a means for sequentially transferring a cage containing seeds along the disinfecting tank and the cooling tank is provided. In a disinfection device consisting of
There is one sterilization tank, and the length of the sterilization tank along the transfer direction of the cage is the length direction in the state where the cage is immersed in the sterilization tank for the time required for hot water disinfection of the seeds. On the other hand, the intermittent transfer means is configured to immerse the cage in the sterilization tank at one end thereof, transfer it to the other end, lift it, and then immerse it in the cooling tank. It is the structure which pulls up. "
It is characterized by that.

  In the present invention, there is one sterilization tank, and the length of the sterilization tank in the sterilization tank is as long as the time required for hot water sterilization of the seed in a state where the cage containing seeds is immersed in the sterilization tank. Since it is configured to move in the direction, it is not necessary to shift the cage containing seeds from immersion in the first disinfection tank to immersion in the second disinfection tank as in the conventional case. Therefore, the time required for disinfection of seeds can be shortened, workability can be improved, and cost can be reduced.

  In addition, since there is only one disinfection tank, the entire apparatus can be reduced in size by this amount, and the cost can be reduced.

In addition, as described in claim 2 , a seed supply stage to the cage is provided on the front side of the disinfection tank in the transfer route of the cage, and a draining stage for the cage is provided on the rear side of the cooling tank. By providing the structure, it is possible to perform seed supply to the cage, disinfection, cooling, and draining in a series of steps, so that the above-described effects can be further promoted.

  An embodiment of the present invention will be described below with reference to the drawing of FIG.

  In this figure, reference numeral 1 denotes a floor surface. The floor surface 1 has a supply stage 2, an open top disinfection tank 3 containing hot water 3a, and an open top cooling tank containing cold water 4a. 4 and the draining stage 5 are arranged in a line.

  Reference numeral 6 denotes the overhead traveling rail. The overhead traveling rail 6 extends above the supply stage 2, the disinfecting tank 3, the cooling tank 4 and the draining stage 5 along the draining stage. The end of the stage 5 side and the start end of the supply stage 2 side are continuously connected so as to be endless.

  The ceiling traveling rail 6 is provided with at least five self-propelled trolleys 7a, 7b, 7c, 7d, and 7e, and each of the trolleys 7a, 7b, 7c, 7d, and 7e is hung on this. The trolleys 7a, 7b, 7c, 7d, and 7e are provided with an elevating mechanism for elevating and lowering the cage 8, and the pitch intervals P are maintained under the same pitch interval P between them. The horizontal movement is performed only along the overhead traveling rail 6, where the lateral movement is stopped for an appropriate time (about 5 minutes) and then moved laterally by the pitch interval P. It is configured.

  That is, the trolleys 7 a, 7 b, 7 c, 7 d, and 7 e move sideways up to a location above the supply stage 2, the cooling tank 4, and the draining stage 5 while moving along the ceiling running rail 6. When moved, the lateral movement is stopped for an appropriate time (about 5 minutes), and the cage 8 is lowered and then raised during that time, and when it reaches one end of the sterilization tank 3, the lateral movement is appropriately performed. When the cage 8 is lowered for a period of time (about 5 minutes) and the cage 8 is lowered, and the cage 8 is moved downward from one end to the other end of the sterilization tank 3, the lateral movement is appropriately performed. After stopping only (about 5 minutes), the cage 8 is raised.

  In this configuration, when each of the trolleys 7a, 7b, 7c, 7d, and 7e moves laterally to the position of the supply stage 2, the cage 8 is lowered and placed on the supply stage 2, and the lateral movement is performed in this state. By stopping for about 5 minutes, an appropriate amount of the target seed to be sterilized in the cage 8 is supplied in the cage 8 while being put in or out of the basket.

  Next, each of the trolleys 7a, 7b, 7c, 7d, and 7e moves up the cage 8 containing the seeds, then moves horizontally to one end in the disinfection tank 3, then moves down the cage 8, and moves horizontally in this state. Is stopped for about 5 minutes, so that the cage 8 is immersed in the warm water in the disinfection tank 3 and predetermined warm water disinfection is started.

  Next, each of the trolleys 7a, 7b, 7c, 7d, and 7e moves sideways to the other end of the disinfection tank 3 while the cage 8 is immersed in warm water, and the other end of the cage 8 After the lateral movement is stopped for about 5 minutes, the cage 8 is lifted to lift the hot water in the disinfecting tank 3 and finish the hot water disinfection.

  Next, when each of the trolleys 7a, 7b, 7c, 7d, and 7e moves sideways to the location of the cooling tank 4 while the cage 8 is raised, the cage 8 is lowered, and in this state, the lateral movement is reduced. By stopping for about 5 minutes, the cage 8 is immersed in the cold water in the cooling tank 4 to perform predetermined cooling.

  When this cooling is completed, each of the trolleys 7a, 7b, 7c, 7d, 7e is lifted up so that the cage 8 rises from the cooling tank 4, and then moves laterally to the location of the draining stage 5 and descends. The seed is drained by placing it on the draining stage 5 and stopping the lateral movement for about 5 minutes in this state.

  When the draining is completed, the trolleys 7a, 7b, 7c, 7d, and 7e are returned from the draining stage 5 to the supply stage 2, and in the middle of the return, seeds from the cage 8 are returned. Take out (unload).

  In this case, the lateral movement from the supply stage 2 to one end of the sterilization tank 3, the lateral movement from one end to the other end of the sterilization tank 3, and the other end of the sterilization tank 3 to the cooling tank 4. The horizontal movement and the horizontal movement of the draining stage 50 from the cooling bath 4 are performed at the same time.

  Furthermore, the cage 8 is lowered at one end of the sterilization tank 3 and the cage 8 is raised at the other end of the sterilization tank 3 at the same time.

  In the present invention, warm water disinfection of seeds is carried out by immersing the cage 8 containing the seeds in one end of the disinfection tank 3 and laterally moving to the other end of the disinfection tank 3 while being immersed. Is what you do.

  Therefore, the length L along the transfer direction of the cage 8 in the sterilization tank 3 is a state in which the cage 8 is immersed in the sterilization tank 3 for a time necessary for the disinfection of the seed (about 10 minutes). By setting the length dimension to be transferred in the length direction, the warm water disinfection of the seed is changed from the immersion in the first disinfection tank to the second disinfection tank as in the conventional case. It can be carried out only by immersion in one disinfection tank 3 without shifting.

It is a figure which shows embodiment of this invention.
