Effect of the Invention

[0006] According to the invention of claim 1 or claim 8, the pure pollen contained in the crude pollen is dispersed in a solvent, and then the anther husks are recovered from the solvent in which the pure pollen has diffused, and furthermore, the pure pollen is recovered from the solvent after the anther husks have been recovered, thereby enabling the pure pollen and the anther husks to be separated with high accuracy, and improving the recovery rate of the pure pollen. According to the invention of claim 2 or claim 9, the solvent after collecting the pure pollen is returned to the pure pollen diffusion section (pure pollen diffusion process), so that a closed system device in which the solvent circulates can be configured.

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0009] [Pure pollen purification method] As shown in Figure 1, a pure pollen refining method according to one embodiment of the present invention is a method for refining pure pollen from crude pollen containing pure pollen and anther shells, and includes a crude pollen supplying process (S1) for supplying crude pollen, a pure pollen diffusing process (S2) for diffusing the pure pollen contained in the crude pollen into a solvent, a first recovery process (S3) for recovering anther shells from the solvent into which the pure pollen has been diffused, and a second recovery process (S4) for recovering pure pollen from the solvent after the anther shells have been recovered.

[0010] According to this method for refining pure pollen, the pure pollen contained in the crude pollen is dispersed in a solvent, the anther husks are then recovered from the solvent in which the pure pollen has diffused, and the pure pollen is then recovered from the solvent after the anther husks have been recovered. This allows the pure pollen and the anther husks to be separated with high accuracy, thereby improving the recovery rate of pure pollen.

[0011] In addition, as shown in Fig. 1, the solvent after collecting the pure pollen is returned to the pure pollen diffusion process (S2), so a closed system in which the solvent circulates can be constructed. This not only makes it possible to make the process highly safe despite using a solvent, but also allows the pure pollen collection process to be carried out continuously.

[0012] The pure pollen collected by the method for refining pure pollen of the present invention is from crops that require artificial pollination, and representative examples include fruit trees such as Japanese pear, kiwi fruit, apple, plum, and cherry, but the method for refining pure pollen of the present invention may also be applied to plants other than fruit trees. In addition, when the size of the anther and the pure pollen of Japanese pear, kiwi fruit, apple, plum, and cherry were measured using an optical microscope, the size of the anther was estimated to be about 1 to 2 mm (however, it may be broken down into smaller pieces), and the size of the pure pollen was estimated to be about 0.024 to 0.043 mm.

[0013] In addition, a volatile organic solvent is suitable as a solvent for collecting pure pollen, and a representative example of this is acetone (CH 3 COCH 3 In the present embodiment, acetone is used. Examples of such volatile organic solvents include diethyl ether (C2 H 5 O.C. 2 H 5 , boiling point 34.6 °C), chloroform (CHCl 3 , boiling point 61.2℃), cyclohexane (C 6 H 12 , boiling point 80.7℃), n-hexane (C 6 H 14 However, it has been confirmed that these organic solvents do not have a significant effect on the pure pollen collected when treated for a short period of time.

[0014] [Pure pollen refining device] Next, a pure pollen refining device 1 that enables the above-mentioned pure pollen refining method will be described with reference to Figs. 2 to 5.

[0015] The pure pollen refinement apparatus 1 shown in Figures 2 to 4 is an apparatus for refining pure pollen from crude pollen containing pure pollen and anther husks, and is equipped with a crude pollen supply section 2 that supplies crude pollen, a pure pollen diffusion section 3 that diffuses the pure pollen contained in the crude pollen into a solvent, a first recovery section 4 that recovers the anther husks from the solvent in which the pure pollen has been diffused, and a second recovery section 5 that recovers pure pollen from the solvent after the anther husks have been recovered.

[0016] 2 to 5, the coarse pollen supply unit 2 includes a hopper 21 into which coarse pollen is fed, a feed roller 22 rotatably arranged at the bottom of the hopper 21, and a motor 23 for rotating the feed roller 22. A plurality of grooves 22a for taking in the coarse pollen are formed on the outer periphery of the feed roller 22. For example, the feed roller 22 of this embodiment has two grooves 22a on the outer periphery along the rotation axis direction.

[0017] When the delivery roller 22 is rotated with coarse pollen fed into the hopper 21, the coarse pollen taken into the groove 22a of the delivery roller 22 is carried downward along the outer periphery of the delivery roller 22 and falls from the groove 22a near the lowest point. By repeating this process, a constant amount of coarse pollen can be supplied to the pure pollen spreading section 3. The amount and speed of coarse pollen supplied by the coarse pollen supply section 2 can be adjusted based on the rotation speed of the delivery roller 22, the number and shape (length, width, depth) of the groove 22a, etc.

[0018] The pure pollen diffusion unit 3 includes a solvent storage tank 31 capable of storing a solvent, and a gutter-shaped chute 32 that slides the coarse pollen supplied from the coarse pollen supply unit 2 down into the solvent storage tank 31 on an inclined surface. This allows the coarse pollen supplied from the coarse pollen supply unit 2 to be immersed in the solvent in the solvent storage tank 31, and the pure pollen contained in the coarse pollen to be diffused in the solvent. In FIG. 4, the two-dot chain line L1 in the solvent storage tank 31 indicates the liquid level of the solvent stored in the solvent storage tank 31.

[0019] The solvent tank 31 is supported at an adjustable angle via a plurality of supports 1b on the base 1a of the pure pollen refining device 1. In addition, since the chute 32 is disposed integrally within the solvent tank 31, the angle of the chute 32 can be changed based on the angle adjustment of the solvent tank 31, and the speed at which the crude pollen slides down can be adjusted.

[0020] The first collection section 4 includes a first filter 41 disposed at the inclined lower end of the chute 32, and a pump 42 for sending the solvent that has passed through the first filter 41 to the second collection section 5. The first filter 41 has openings set to pass the solvent in which the pure pollen has been diffused and not to pass the anthers, so that only the solvent in which the pure pollen has been diffused can be sent to the second collection section 5 while collecting the anthers. A metal mesh (e.g., SUS net) can be used as the first filter 41. The openings of the first filter 41 are selected according to the size (type) of the anthers and pure pollen to be collected. For example, in the case of the above-mentioned Japanese pear, kiwi fruit, apple, plum, and cherry, the openings are set to about 0.11 mm, which is sufficiently smaller than the anthers and larger than the pure pollen, in order to collect fine anther pieces resulting from the crushing of the anthers. This allows the solvent in which the pure pollen has been diffused to pass while collecting the anthers and the crushed anthers.

[0021] The pump 42 is, for example, a magnetic pump, which draws in the solvent from the bottom of the solvent storage tank 31 via a suction pipe 43 and delivers the drawn-in solvent to the second recovery section 5 via a delivery pipe 44 .

[0022] The second collection section 5 includes a pure pollen separation tank 51 that stores the solvent in which the pure pollen is dispersed and settles the pure pollen in the solvent, and a second filter 52 that allows the solvent to pass through but does not allow the pure pollen to pass through. The pure pollen separation tank 51 is, for example, a cylindrical resin tank that is arranged in an inclined manner, and a round hole 51a (see FIG. 4) is formed at the bottommost position of the pure pollen separation tank 51 for dripping the solvent containing the settled pure pollen. The pure pollen that settles in the pure pollen separation tank 51 gathers at the bottommost position of the pure pollen separation tank 51 due to the inclination of the pure pollen separation tank 51, the roundness of the bottom, the flow of the inflowing solvent, and the like, and drips from the round hole 51a. The size of the round hole 51a is set according to the capacity of the second filter 52. For example, the size of the round hole 51a is set so that the amount of solvent on the second filter 52 is not too small and does not increase in volume and overflow. In FIG. 4, the two-dot chain line L2 in the pure pollen separation tank 51 indicates the liquid level of the solvent accumulated in the pure pollen separation tank 51.

[0023] The second filter 52 is disposed below the pure pollen separation tank 51, and while collecting pure pollen from the solvent dropped from the bottom of the pure pollen separation tank 51, the second filter 52 passes the solvent after collecting the pure pollen. In other words, the pure pollen is allowed to settle at the bottom of the pure pollen separation tank 51, and then the solvent is dropped from the bottom of the pure pollen separation tank 51 to collect the pure pollen, so that the pure pollen can be collected efficiently. The solvent that has passed through the second filter 52 falls onto the chute 32. A metal mesh (e.g., SUS net) can be used as the second filter 52. The opening of the second filter 52 is selected according to the size (type) of the pure pollen to be collected. For example, in the case of the above-mentioned Japanese pear, kiwi fruit, apple, plum, and cherry, the opening is set to about 0.016 mm, which is smaller than the pure pollen of these fruits. This allows the solvent to pass while collecting the pure pollen of Japanese pear, kiwi fruit, apple, plum, and cherry. In other words, the openings set for the first filter 41 and the second filter 52 are different, and the openings of the second filter 52 are set smaller than those of the first filter 41.

[0024] In addition, the pure pollen separation tank 51 allows the solvent in the upper layer to overflow while allowing the pure pollen contained in the solvent to settle. The overflowing solvent is returned to the pure pollen diffusion section 3 via the return pipe 53. This allows the flow rate and flow speed of the circulating solvent to be appropriately controlled, allowing efficient continuous operation. In addition, the overflowing solvent is returned to the inclined upstream side of the chute 32 via the return pipe 53, so that not only can the solvent returned to the top of the chute 32 promote the flow of coarse pollen, but also the solvent can be washed off the top of the chute 32, allowing good continuous operation to be achieved. In particular, the chute 32 in this embodiment has a trough shape, and the coarse pollen and solvent are brought to the center (the bottom of the trough) and slide down, allowing the pure pollen contained in the coarse pollen to be well diffused in the solvent.

[0025] Furthermore, the pure pollen refining device 1 of this embodiment is provided with a transparent case 6 that covers the second collection section 5. The case 6 blocks the outflow path of the volatile solvent and forms a closed space from which the solvent does not flow out. This allows the pure pollen to be efficiently collected using a solvent with a low boiling point while maintaining good safety.

[0026] According to the present embodiment configured as described above, the pure pollen purification device 1 purifies pure pollen from crude pollen containing pure pollen and anther husks, and is equipped with a crude pollen supply section 2 that supplies crude pollen, a pure pollen diffusion section 3 that diffuses the pure pollen contained in the crude pollen into a solvent, a first recovery section 4 that recovers the anther husks from the solvent in which the pure pollen has been diffused, and a second recovery section 5 that recovers pure pollen from the solvent after the anther husks have been recovered, thereby making it possible to accurately separate pure pollen and anther husks, thereby improving the recovery rate of pure pollen.

[0027] In addition, the solvent after collecting the pure pollen is returned to the pure pollen diffusion section 3, so a closed system in which the solvent circulates can be constructed. This not only makes it possible to provide a high level of safety despite using a solvent, but also allows the pure pollen collection process to be carried out continuously.

[0028] In addition, the pure pollen diffusion section 3 is equipped with a solvent storage tank 31 capable of storing a solvent, and a chute 32 that slides the coarse pollen supplied from the coarse pollen supply section 2 down into the solvent storage tank 31. The solvent after collecting the pure pollen is returned onto the chute 32, so that the solvent returned onto the chute 32 can promote the flow of the coarse pollen.

[0029] In addition, the first recovery section 4 is equipped with a first filter 41 that allows the solvent in which pure pollen has diffused to pass but does not allow anther husks to pass, and a pump 42 that sends the solvent that has passed through the first filter 41 to the second recovery section 5, so that the anther husks can be recovered while the solvent after the anther husks have been collected can be reliably sent to the second recovery section 5.

[0030] In addition, the second recovery section 5 is equipped with a pure pollen separation tank 51 that stores the solvent in which the pure pollen has been dispersed and causes the pure pollen in the solvent to settle, and a second filter 52 that allows the solvent to pass but not the pure pollen to pass through.The solvent containing the settled pure pollen is dripped from the bottom of the pure pollen separation tank 51 onto the second filter 52, so that pure pollen can be efficiently recovered from the solvent after the anther shells have been recovered.

[0031] In addition, since the solvent that overflows in the pure pollen separation tank 51 is returned to the pure pollen diffusion section 3, the flow rate and flow speed of the circulating solvent can be appropriately controlled, enabling efficient continuous operation.

[0032] In addition, since the solvent that has passed through the second filter 52 is also returned to the pure pollen-diffusing section 3, the flow rate and flow speed of the circulating solvent can be more appropriately controlled.

[0033] It is needless to say that the present invention is not limited to the above embodiment. For example, the openings of the first filter 41 and the second filter 52 are not limited to the above numerical values, and can be arbitrarily selected according to the size (type) of the anther shells and pure pollen to be collected.
