Description

Technical Field

[0001] The invention relates to the technical field of Trichosanthes seeds ripening, and in particular to a Trichosanthes seeds ripening preservation system and a preservation method. Background Art

[0002] Trichosanthes kirilowii is also called medicinal melon, and its scientific name is Trichosanthes kirilowii. It is a treasure from head to toe. The melon shell can be used as medicine. The mature Trichosanthes kirilowii seeds can be used as health and leisure food after being dried. The root of Trichosanthes kirilowii can be made into Radix Trichosanthis, which has great utilization value and high economic benefits. The picking time of Trichosanthes kirilowii is generally after the fruit is fully ripe, the surface of the fruit turns yellow, and even after the turtle back pattern appears. If the Trichosanthes kirilowii is picked too early, the inside of the fruit has not fully developed, the taste is not good, the fragrance is insufficient, and the taste is affected. Due to factors such as season and growth period, the autumn fruit in Trichosanthes kirilowii generally cannot mature normally. Some Trichosanthes kirilowii that are not fully ripe need to be ripened.

[0003] A common ripening method is to place the Trichosanthes fruit into a ripening tank filled with ripening liquid. The chemical substances in the ripening liquid can simulate the hormones released during the natural ripening process of the plant to ripen the Trichosanthes fruit. During the ripening process, the effective ingredients of the ripening liquid at different positions in the ripening tank are consumed at different rates. In order to avoid uneven ripening of the Trichosanthes fruit in the ripening tank, the ripening liquid in the ripening tank needs to be stirred. Stirring the ripening liquid will cause the Trichosanthes fruit to move with the flow of the ripening liquid, causing the Trichosanthes fruit to collide and form physical damage. During the ripening process of the Trichosanthes fruit, the damage to the Trichosanthes fruit will affect the integrity of the Trichosanthes seeds, and will also cause problems such as material loss and pathogen invasion.

The trichosanthes will fall into the inside of the protective sleeve and float on the liquid surface of the ripening liquid. Pull the upper end of the spiral plate upward and lock it; S2: The motor drives the mesh disk and the spiral plate to rotate forward. The trichosanthes are screwed into and gathered at the lower position of the spiral gap formed by the spiral plate. Multiple blocking rods will fall at the lower position of the spiral gap under the extrusion of the trichosanthes.

[0017] 3. During the reverse rotation of the spiral plate of the present invention, it will drive multiple blocking rods and the upper vertical block to slide upward along the upper vertical groove from bottom to top.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] AsFigures 1 to 11 As shown below, the present invention includes the following embodiments: Embodiment 1: A Trichosanthes kirilowii Maxim. seed ripening and preservation system, including a ripening tank 1 and a tank cover 11 at the upper port of the ripening tank 1; a breathable pipe 12 is vertically penetrated through the tank cover 11; the bottom of the ripening tank 1 is fixedly connected with supporting feet 13; a perforated net disk 2 is rotatably connected at a position near the lower part of the inner wall of the ripening tank 1; a central shaft 3 is vertically penetrated and fixedly connected at the center of the net disk 2; the lower end of the central shaft 3 penetrates through the bottom wall of the ripening tank 1 and is fixedly connected with a motor 31; the outer wall of the motor 31 is fixedly connected with the supporting feet 13; a chassis 4 is movably and sealingly connected at a position near the lower part of the inner wall of the ripening tank 1; a liquid outlet pipe 41 with a valve is eccentrically arranged downward on the chassis 4; the center of the chassis 4 is movably and sealingly connected with the outer wall of the central shaft 3; a lower vertical groove 14 is arranged at a position near the lower part of the inner wall of the ripening tank 1; a lower vertical block 15 is slidably and sealingly connected in the lower vertical groove 14; the lower vertical block 15 is fixedly connected with the outer wall of the chassis 4; an annular track 32 is obliquely arranged on the outer wall of the central shaft 3; one end of the annular track 32 is higher than the other end in the vertical direction; a track block 33 is movably and sealingly connected in the annular track 32; the track block 33 is fixedly connected with the chassis 4; the chassis 4 is located below the net disk 2; a spiral plate 5 is connected to the outer wall of the central shaft 3 above the net disk 2; the inner edge of the spiral plate 5 contacts the central shaft 3, and the outer edge contacts the inner wall of the ripening tank 1.

[0023] After making incisions on the pericarp of the Trichosanthes kirilowii Maxim. fruit that extend to the pulp, perform shady drying treatment. Then, after opening the tank lid 11, close the valve in the liquid outlet pipe 41, and pour the ripening liquid along the upper port of the ripening tank 1 into the ripening tank 1. The liquid level height of the ripening liquid does not exceed the height of the upper end of the spiral plate 5. Then, pour the Trichosanthes kirilowii Maxim. into the ripening tank 1. Due to the loose and porous internal tissue of the Trichosanthes kirilowii Maxim., there are a large number of voids, resulting in too low density of the Trichosanthes kirilowii Maxim. itself. The density of the Trichosanthes kirilowii Maxim. is less than the density of the ripening liquid, so the Trichosanthes kirilowii Maxim. will float on the surface of the ripening liquid. The motor 31 will drive the central shaft 3 to rotate, and the rotating central shaft 3 will drive the mesh disk 2 and the spiral plate 5 to rotate. The upper end of the spiral plate 5 is higher than the liquid level of the ripening liquid. As the spiral plate 5 rotates, the Trichosanthes kirilowii Maxim. can be spiraled into the spiral gap 51 of the spiral plate 5 in the forward rotation. The Trichosanthes kirilowii Maxim. entering the spiral gap 51 will approach the mesh disk 2 from top to bottom. The mesh disk 2 will rotate with the rotation of the central shaft 3. As the number of Trichosanthes kirilowii Maxim. entering the spiral gap 51 increases, the Trichosanthes kirilowii Maxim. will converge at the lower position in the spiral gap 51, and multiple Trichosanthes kirilowii Maxim. will be tightly pressed against each other in the spiral gap 51 to achieve positioning. During the rotation of the central shaft 3, the annular track 32 on the outer wall of the central shaft 3 moves relative to the track block 33. The track block 33 is movably and sealingly connected to the annular track 32. Therefore, the ripening liquid above the chassis 4 will not leak along the annular track 32. The annular track 32 moves with the rotation of the central shaft 3, and the track block 33 will circulate in the annular track 32. The track block 33 will circulate from the lowest point of the annular track 32 to the highest point, and then from the highest point to the lowest point. The lower vertical block 15 on the outer wall of the chassis 4 is slidably and sealingly connected in the lower vertical groove 14. Therefore, the chassis 4 will move up and down vertically along the central shaft 3. During the upward movement of the chassis 4, the ripening liquid between the lower surface of the mesh disk 2 and the upper surface of the chassis 4 will flow upward. The ripening liquid will pass through the holes on the mesh disk 2 and enter the spiral gap 51. Since the spiral plate 5 will not stop rotating after spiraling the Trichosanthes kirilowii Maxim. into the spiral gap 51, the Trichosanthes kirilowii Maxim. in the spiral gap 51 is always in a converged and tightly pressed state. Therefore, the ripening liquid will not drive the Trichosanthes kirilowii Maxim. to move with the flow of the ripening liquid during the contact with the Trichosanthes kirilowii Maxim. During the downward movement of the chassis 4, the space between the lower surface of the mesh disk 2 and the upper surface of the bottom disk will become larger to form a negative pressure. In this way, the ripening liquid above the mesh disk 2 will pass through the holes on the mesh disk 2 and enter the space between the lower surface of the mesh disk 2 and the upper surface of the chassis 4 for mixing. The mixed ripening liquid will pass through the mesh disk 2 again with the upward movement of the chassis 4. This process is repeated, so that the ripening liquid ripens the Trichosanthes kirilowii Maxim. in the ripening tank 1 during the flow. During the ripening process, the tank lid 11 will be covered on the upper port of the ripening tank 1 to prevent the splashing of the ripening liquid. During the ripening process, the cooperation between the annular track 32 and the track block 33 to realize the up and down movement of the chassis 4 can also be replaced by an electric push rod to push the chassis 4 up and down; during the ripening process of the Trichosanthes kirilowii Maxim., chemical substances in the ripening liquid, such as ethephon, can simulate the hormones released during the natural ripening process of plants and promote the ripening of the Trichosanthes kirilowii Maxim.;During the ripening process, a megasonic transducer can be installed inside the ripening tank 1. By utilizing the physical effect of megasonic vibration, it can promote the more effective penetration of the ripening liquid into the Trichosanthes kirilowii fruits, accelerating the ripening process. After the Trichosanthes kirilowii is ripened, the motor 31 will drive the central shaft 3 to rotate in the reverse direction, and at the same time, the tank cover 11 will be opened. During the reverse rotation of the central shaft 3, the spiral plate 5 will be driven to rotate in the reverse direction. During the reverse rotation of the spiral plate 5, multiple Trichosanthes kirilowii in the spiral gap 51 will be driven to move. In addition, under the action of buoyancy, the Trichosanthes kirilowii will float upward, and the floating Trichosanthes kirilowii will move upward along the spiral gap 51, thus moving out of the spiral gap 51 and floating on the liquid surface of the ripening liquid. Then, the ripened Trichosanthes kirilowii can be fished out. After monitoring that the chemical substances in the ripening liquid are within the standard range, the next batch of Trichosanthes kirilowii ripening can be carried out. Otherwise, the valve in the liquid discharge pipe 41 is opened to replace the ripening liquid. During the ripening process of Trichosanthes kirilowii, due to the forward rotation of the spiral plate 5, multiple Trichosanthes kirilowii are screwed into and converge at the lower position of the spiral gap 51 formed by the spiral plate 5, so that all the Trichosanthes kirilowii are immersed in the ripening liquid, preventing the Trichosanthes kirilowii from floating up and affecting the ripening effect. The rotation of the spiral plate 5 can also stir the ripening liquid, making the chemical substances contained in the ripening liquid in the ripening tank 1 more evenly distributed, ensuring the uniformity of Trichosanthes kirilowii ripening. After ripening, the Trichosanthes kirilowii is separated, dried, sterilized for the pericarp, seeds and peel, and then sealed and stored. In the present invention, through the forward rotation of the spiral plate 5 inside the ripening tank 1, the Trichosanthes kirilowii is screwed into and converges at the lower position of the spiral gap 51 formed by the spiral plate 5. Multiple Trichosanthes kirilowii in the spiral gap 51 are tightly pressed against each other and cannot be washed away by the flowing ripening liquid, so that multiple Trichosanthes kirilowii cannot form mechanical impacts on each other and cause damage, ensuring the integrity of Trichosanthes kirilowii during the ripening process.

[0024] Embodiment 2: A rotating block 34 is rotatably connected to the outer wall of the central shaft 3; the rotating block 34 is fixedly connected to the lower end of the spiral plate 5; the spiral plate 5 is made of an internal elastic metal material and is coated with an elastic non-metal material on the surface, such as rubber.

[0025] In this embodiment, a movable sleeve 6 is movably sleeved on the upper end of the central shaft 3; a movable hole 61 is provided through the inner and outer walls of the movable sleeve 6; a movable block 62 is movably inserted into the movable hole 61; one end of the movable block 62 away from the center of the movable sleeve 6 is connected to the outer wall of the movable sleeve 6 by an elastic cord 63; the movable sleeve 6 is connected to the upper end of the spiral plate 5.

[0026] In this embodiment, an annular block 64 is fixedly connected to the lower position of the outer wall of the movable sleeve 6; the annular block 64 is lower than the upper end of the spiral plate 5 in the vertical direction; the inner edge of the upper end of the spiral plate 5 is in contact with the outer wall of the movable sleeve 6.

[0027] Before pouring the trichosanthes kirilowii maxim into the ripening tank 1, first pull the movable sleeve 6 upward. During the upward movement of the movable sleeve 6, the annular block 64 at the lower position of the outer wall will be driven to move upward. During the upward movement of the annular block 64, it will support the upper end of the spiral plate 5, causing the upper end of the spiral plate 5 to move upward, thereby expanding the spiral gap 51 formed by the spiral plate 5. During the upward movement of the movable sleeve 6, it will move along the outer wall of the upper end of the central shaft 3. After the upward movable sleeve 6 drives the movable hole 61 to pass over the upper end of the central shaft 3, the end of the movable block 62 close to the center of the movable sleeve 6 will be inserted into the inner side of the movable sleeve 6 under the pulling of the elastic cord 63. The end of the movable block 62 close to the center of the movable sleeve 6 will be stuck above the upper end of the central shaft 3 to achieve the positioning after the spiral plate 5 is pulled open. Subsequently, pour the trichosanthes kirilowii maxim into the ripening tank 1. The trichosanthes kirilowii maxim will float on the surface of the ripening liquid. As the spiral plate 5 rotates, the spiral plate 5 can rotate the trichosanthes kirilowii maxim into and converge it at the lower position within the spiral gap 51. After all the trichosanthes kirilowii maxim enter the spiral gap 51 formed by the spiral plate 5, without stopping the spiral plate 5, directly hold the movable sleeve 6 and pull out the movable block 62 radially outward along the movable sleeve 6. The movable block 62 will overcome the elastic force of the elastic cord 63 and move away from the center of the movable sleeve 6. The movable block 62 will move out of the inner side of the movable sleeve 6, enabling the movable sleeve 6 to move downward smoothly after being unlocked. The movable sleeve 6 will move downward along the outer wall of the upper end of the central shaft 3. After the movable hole 61 is vertically lower than the upper end of the central shaft 3, the movable block 62 will abut against the outer wall of the central shaft 3. The movable sleeve 6 will move downward under the elastic force of the spiral plate 5 itself. The spiral plate 5 itself has an elastic force and will tighten downward. During the tightening process of the spiral plate 5, it can clamp the trichosanthes kirilowii maxim within the spiral gap 51, thereby further limiting the position of the trichosanthes kirilowii maxim and making the trichosanthes kirilowii maxim more stable during the ripening process. After the trichosanthes kirilowii maxim is ripened, pull the movable sleeve 6 upward again to expand the spiral pitch formed by the spiral plate 5, so that after the trichosanthes kirilowii maxim is released from the clamping, it can be smoothly removed under the reverse rotation of the spiral plate 5.

[0028] Embodiment 3: The upper surface of the network disk 2 is connected with a protective sleeve 21; the inner wall of the protective sleeve 21 is in contact with the outer edge of the spiral plate 5; the protective sleeve 21 can rotate along with the rotation of the spiral plate 5.

[0029] In this embodiment, there is a gap between the outer surface of the protective sleeve 21 and the inner wall of the ripening tank 1; the upper end of the protective sleeve 21 is vertically lower than the upper port of the ripening tank 1.

[0030] During the rotation of the central shaft 3, the net disk 2 and the spiral plate 5 will be driven to rotate. During the forward rotation of the spiral plate 5, the central shaft 3 will drive the protective sleeve 21 to rotate through the net disk 2, and the spiral gap 51 formed by the spiral plate 5 rotates synchronously with the inner wall of the protective sleeve 21. Therefore, the position where the trichosanthes in the spiral gap 51 contacts the inner wall of the protective sleeve 21 will not cause frictional damage during the ripening process. A layer of rubber material can be coated on the inner wall of the protective sleeve 21 to protect the trichosanthes in the spiral gap 51; during the ripening process, the forward rotation of the spiral plate 5 will drive the ripening liquid inside the protective sleeve 21 to flow downward along the spiral gap 51, and the ripening liquid can also flow along the trichosanthes gap in the spiral gap 51. When the chassis 4 approaches the net disk 2 under the drive of the central shaft 3, the ripening liquid between the lower surface of the net disk 2 and the upper surface of the chassis 4 passes through the net disk 2 and flows into the gap between the outer wall of the protective sleeve 21 and the inner wall of the ripening tank 1. The ripening liquid will flow upward along the gap between the outer wall of the protective sleeve 21 and the inner wall of the ripening tank 1, and finally flow into the inside of the protective sleeve 21 along the upper port of the protective sleeve 21. Under the forward rotation of the spiral plate 5, the ripening liquid inside the protective sleeve 21 will be driven to flow downward along the spiral gap 51 again, thus forming a cycle, so that the ripening liquid in the ripening tank 1 can contact the trichosanthes, improving the ripening effect; in this embodiment, the size of the trichosanthes is larger than the gap between the outer wall of the protective sleeve 21 and the inner wall of the ripening tank 1.

[0031] Embodiment 4: The inner wall of the protective sleeve 21 is vertically provided with an upper vertical groove 22; an upper vertical block 7 is slidably connected up and down in the upper vertical groove 22; a plurality of blocking rods 71 are connected to the upper vertical block 7 close to the central shaft 3; the upper end of the upper vertical groove 22 is lower than the upper end of the protective sleeve 21, and the lower end of the upper vertical groove 22 penetrates downward.

[0032] In this embodiment, anti-slip strips 23 are uniformly arranged along the circumference on the outer wall of the protective sleeve 21; the anti-slip strips 23 are vertically arranged; a limiting groove 16 is penetrated through the inner and outer walls of the ripening tank 1; a limiting strip 17 is slidably connected in the limiting groove 16; one end of the limiting strip 17 away from the central shaft 3 is connected to the outer wall of the ripening tank 1 through a first spring 18.

[0033] After the trichosanthes kirilowii maxim is poured into the inner side of the ripening tank 1, the trichosanthes kirilowii maxim will fall into the inner side of the protective sleeve 21. As the spiral plate 5 rotates forward, the spiral plate 5 will screw the trichosanthes kirilowii maxim into the spiral gap 51. A plurality of blocking rods 71 are located in the spiral gap 51 along with the upper vertical block 7. As the trichosanthes kirilowii maxim moves along the spiral gap 51, the trichosanthes kirilowii maxim will squeeze the blocking rods 71 to move along the gap of the spiral plate 5. When the blocking rods 71 are pressed, they will drive the upper vertical block 7 to slide downward along the upper vertical groove 22. The blocking rods 71 will move to a lower position of the upper vertical groove 22 under the extrusion of the trichosanthes kirilowii maxim. The blocking rods 71 will be stuck at the lower position of the spiral gap 51 and cannot move further. In this way, the protective sleeve 21 will rotate along with the rotation of the spiral plate 5. During the ripening process, when the spiral plate 5 rotates forward, the protective sleeve 21 will rotate synchronously along with the rotation of the spiral plate 5. During the ripening process, the density of the trichosanthes kirilowii maxim may increase due to the infiltration of the ripening liquid. In order to enable the trichosanthes kirilowii maxim to be smoothly removed from the spiral gap 51, the limiting strip 17 is pressed to overcome the first spring 18 and slide along the limiting groove 16. The limiting strip 17 will abut against the outer wall of the protective sleeve 21. During the reverse rotation of the spiral plate 5, the protective sleeve 21 will be driven to rotate in the reverse direction. After the anti-slip strips 23 on the outer wall of the protective sleeve 21 are blocked by the limiting strip 17, the protective sleeve 21 cannot rotate along with the reverse rotation of the spiral plate 5. During the reverse rotation of the spiral plate 5, a plurality of blocking rods 71 and the upper vertical block 7 will be driven to slide upward along the upper vertical groove 22 from bottom to top. The upper vertical block 7 will drive a plurality of blocking rods 71 to push the trichosanthes kirilowii maxim in the spiral gap 51 upward along the spiral gap 51 from bottom to top. In this way, even if the density of the trichosanthes kirilowii maxim increases due to the infiltration of the ripening liquid, the trichosanthes kirilowii maxim can be smoothly removed after ripening, making the use of the ripening tank 1 more stable; after all the trichosanthes kirilowii maxim are removed from the spiral gap 51, the limiting strip 17 is released, and the limiting strip 17 will move away from the protective sleeve 21 along the limiting groove 16 under the action of the first spring 18.

[0034] Embodiment 5: A chute 72 is vertically arranged on one side of the upper vertical block 7 facing the central axis 3; a slider 73 is slidably connected in the chute 72; the blocking rod 71 is rotatably connected to the slider 73; adjacent sliders 73 are connected by a second spring 74.

[0035] When the spiral gap 51 formed by the spiral plate 5 expands, adjacent sliders 73 move away from each other under the action of the second spring 74. The sliders 73 will slide along the chute 72, and adjacent sliders 73 will drive adjacent blocking rods 71 to move away from each other. In this way, when the spiral gap 51 expands, a plurality of blocking rods 71 can also block the trichosanthes kirilowii maxim; when the spiral gap 51 formed by the spiral plate 5 shrinks, adjacent sliders 73 are pressed to overcome the second spring 74 and move closer to each other. Adjacent sliders 73 will drive adjacent blocking rods 71 to move closer to each other. In this way, when the spiral gap 51 shrinks, the blocking rods 71 will not cause blocking interference to the shortening of the spiral gap 51.

[0036] Example 6: A method for accelerating the ripening and preserving of Trichosanthes kirilowii seeds. This method is applicable to the above-mentioned system for accelerating the ripening and preserving of Trichosanthes kirilowii seeds. The steps of this method are as follows: S1: After the tank lid 11 is opened, pour the ripening liquid along the upper port of the ripening tank 1, and then pour the Trichosanthes kirilowii seeds into the inner side of the ripening tank 1. The Trichosanthes kirilowii seeds will fall into the inner side of the protective sleeve 21 and float on the liquid surface of the ripening liquid. Pull the upper end of the spiral plate 5 upward and lock it; S2: The motor 31 drives the mesh disk 2 and the spiral plate 5 to rotate forward. The Trichosanthes kirilowii seeds are screwed and gathered to the lower position of the spiral gap 51 formed by the spiral plate 5. A plurality of blocking rods 71 will fall to the lower position of the spiral gap 51 under the extrusion of the Trichosanthes kirilowii seeds. The protective sleeve 21 rotates with the rotation of the spiral plate 5; Release the upper end of the spiral plate 5; S3: The spiral plate 5 will make the ripening liquid flow downward along the spiral gap 51 into the lower surface of the mesh disk 2 and the upper surface of the chassis 4. The ripening liquid between the lower surface of the mesh disk 2 and the upper surface of the chassis 4 will pass through the mesh disk 2 and flow into the space between the outer wall of the protective sleeve 21 and the inner wall of the ripening tank 1. The ripening liquid between the inner wall of the protective sleeve 21 and the inner wall of the ripening tank 1 will flow into the inner side along the upper port of the protective sleeve 21, completing the process of accelerating the ripening of the Trichosanthes kirilowii seeds; S4: After pulling the upper end of the spiral plate 5 upward, place the limiting strip 17 against the outer wall of the protective sleeve 21. The motor 31 drives the spiral plate 5 to rotate in the reverse direction. The Trichosanthes kirilowii seeds are pushed out of the spiral gap 51 by the blocking rods 71 as the spiral plate 5 rotates, and the ripened Trichosanthes kirilowii seeds are fished out.
