Description

Technical Field

[0001] This invention relates to the field of green bean processing technology, specifically to a cooling and draining device for quick-frozen green bean processing. Background Technology

[0002] Frozen green beans are a dish made primarily from green beans. Green beans used for quick-freezing should be fresh, bright green, uniform in shape, long and thin, free of spots, pests, diseases, and other contaminants. In the process of making frozen green beans, they need to be blanched first, then placed in cold water for rapid cooling and drained.

[0003] The invention disclosed in CN115486547B is a cooling and draining device for processing quick-frozen green beans, including a support rod, a feeding unit for feeding and sequentially conveying processed green beans, the feeding unit being located on one side of the support rod; and a processing unit for blanching and cooling green beans, the processing unit being connected to the support rod and located on one side of the feeding unit; the processing unit includes a soaking component for processing green beans, the soaking component being located on one side of the support rod.

[0004] The aforementioned application document describes a method of transferring heat from a hot water tank to a heat conduction box. By utilizing the heat conduction function, heat is circulated within the heat conduction box, thereby accelerating the draining of green beans. However, draining green beans by heating them can easily lead to a deterioration in the taste of the beans, making them less suitable for subsequent purchase and consumption. Furthermore, the overall draining method is rather cumbersome and therefore requires improvement. Summary of the Invention

[0005] This invention proposes a cooling and draining device for quick-frozen green soybean processing, which solves the problems mentioned in the above documents.

[0006] The technical solution of the present invention is as follows: A cooling and draining device for quick-frozen green soybean processing includes a cooling cylinder and a draining filter cylinder. A drain pipe is fixedly connected through the bottom of the cooling cylinder, and a water tank is fixedly connected to the side of the cooling cylinder. A rotating draining mechanism and a water inlet mechanism are provided at the bottom of the cooling cylinder, and a quantitative drainage mechanism is provided inside the drain pipe. The rotating draining mechanism includes a motor, a lifting cylinder, and a pressure chamber. The motor is fixedly installed at the bottom of the cooling cylinder, and a rotating shaft is fixedly connected to the motor through its output shaft. The rotating shaft is rotatably connected through the bottom of the cooling cylinder, and a slider is fixedly connected to the surface of the rotating shaft. The top of the lifting cylinder is fixedly connected to the bottom of the draining filter cylinder, and a sliding groove is provided inside the lifting cylinder. A lifting plate is fixedly connected to the surface of the lifting cylinder, and an annular groove is provided inside the lifting plate. An eccentric plate is fixedly connected to the surface of the rotating shaft. The pressure chamber is fixedly connected through the bottom of the cooling cylinder. An air bladder is provided at one end of the pressure chamber, and a piston rod A is slidably connected to the piston inside the other end of the pressure chamber. A round block is fixedly connected to the end of the piston rod A away from the pressure chamber.

[0007] The slider and the slide groove are both set in two sets, and the two sets of sliders are slidably connected in the two sets of slide grooves respectively. When the rotating shaft rotates, the lifting cylinder will rotate synchronously through the cooperation of the two sets of sliders and the two sets of slide grooves.

[0008] The eccentric disk is close to the side of the airbag away from the pressure chamber, and the airbag is initially in an inflated state. When the rotating shaft drives the eccentric disk to rotate, it will repeatedly squeeze the airbag. When the airbag is squeezed, the air pressure inside it will enter the pressure chamber and push the piston rod A to move upward.

[0009] The circular block is slidably connected in the annular groove. The weight of the drain filter cylinder is greater than the friction between the slider and the groove. The circular block remains stationary under the restriction of piston rod A. When piston rod A moves upward, it will drive the lifting plate to move upward through the circular block. The weight of the drain filter cylinder can drive the slider to move downward along the groove.

[0010] The water inlet mechanism includes a rotating gear and a pressure chamber. The rotating gear is fixedly connected to the surface of the rotating shaft, and the pressure chamber is fixedly connected to the bottom of the cooling cylinder. A return spring is installed inside the pressure chamber, and a piston rod B is slidably connected inside the pressure chamber via the return spring piston. A toothed rod is fixedly connected to the end of the piston rod B away from the pressure chamber. A water suction pipe is inserted through and fixedly connected to the bottom of the pressure chamber, and the end of the water suction pipe away from the pressure chamber is inserted through and fixedly connected to the bottom of the water tank. A water outlet pipe is inserted through and fixedly connected to the top of the pressure chamber, and the end of the water outlet pipe away from the pressure chamber is inserted through and fixedly connected to the side of the cooling cylinder. A one-way valve is installed inside both the water suction pipe and the water outlet pipe.

[0011] The rotating gear is an incomplete gear, and the teeth on the rack are matched with the teeth on the rotating gear. When the rotating gear rotates and its teeth mesh with the teeth on the rack, it will drive the rack to move to the right.

[0012] The one-way valve in the water suction pipe is open to the inside of the pressure chamber, and the one-way valve in the water outlet pipe is open to the cooling cylinder. When a negative pressure is formed in the pressure chamber, water will be drawn into the pressure chamber through the water suction pipe. When the pressure chamber is squeezed, the water inside will be discharged through the water outlet pipe.

[0013] The quantitative drainage mechanism includes a fixed ring, which is fixedly connected to the inside of the drain pipe. The fixed ring has an elongated groove inside, and a telescopic spring is installed inside the elongated groove. A sliding block is slidably connected inside the elongated groove through the telescopic spring. A sliding rod is fixedly connected to the bottom of the sliding block. A closing block is fixedly connected to the end of the sliding rod away from the sliding block. A pull rod is fixedly connected to the bottom of the closing block.

[0014] The outer diameter of the sealing block is equal to the inner diameter of the fixing ring. In the initial state, one-third of the sealing block is located inside the fixing ring. The sealing block is stuck inside the fixing ring, preventing the water in the cooling cylinder from being discharged through the drain pipe.

[0015] The elastic force of the telescopic spring is greater than the weight of the sealing block. The pull rod passes through and is slidably connected to the bottom of the drain pipe. The sealing block can be pulled downward by the pull rod, while the elastic force of the telescopic spring can drive the sealing block to move upward and return to its original position.

[0016] The working principle and beneficial effects of this invention are as follows:

[0017] 1. In this invention, a rotating draining mechanism is provided so that when it is necessary to cool and drain blanched green beans, the green beans can be placed in the draining filter cylinder, and an appropriate amount of cold water can be added to the cooling cylinder. Then, the motor is turned on to drive the rotating shaft to rotate. The rotation of the rotating shaft will drive the lifting cylinder and the draining filter cylinder to rotate through the cooperation of the slider and the sliding groove. At the same time, through the cooperation of components such as the eccentric plate, air bag, and air pressure chamber, the draining filter cylinder will also move up and down repeatedly during the rotation process, so that the green beans can fully contact the cold water and accelerate the cooling efficiency. When the water in the cooling cylinder is drained, the rotation and repeated up and down movement of the draining filter cylinder can also speed up the draining of the green beans.

[0018] 2. In this invention, by setting up a water inlet mechanism, the motor drives the rotating shaft to rotate, causing the drain filter cylinder to rotate and move up and down repeatedly. During this process, the rotating gear, rack, pressure chamber and other components work together to allow the water suction pipe to draw water from the water tank and discharge it to the green beans in the drain filter cylinder through the water outlet pipe. This further improves the cooling efficiency and prevents the water in the cooling cylinder from contacting the green beans and causing the temperature to rise, which would lead to a poor cooling effect.

[0019] 3. By setting up a quantitative drainage mechanism, the cooling water in the cooling cylinder can be kept at a certain level through the cooperation of components such as the fixed ring, telescopic spring, slide rod, and sealing block. This prevents the water level from being too high due to water entering through the outlet pipe, and also prevents the water level from being too low due to water draining too quickly through the drain pipe, thus further improving the stability of the overall device.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] like Figures 1-5 As shown, this embodiment proposes a cooling and draining device for quick-frozen green soybean processing, including a cooling cylinder 1 and a draining filter cylinder 2. A drain pipe 3 is fixedly connected to the bottom of the cooling cylinder 1, and a water tank 4 is fixedly connected to the side of the cooling cylinder 1. A rotating draining mechanism 5 and a water inlet mechanism 6 are provided at the bottom of the cooling cylinder 1, and a quantitative drainage mechanism 7 is provided inside the drain pipe 3. The rotating draining mechanism 5 includes a motor 511, a lifting cylinder 53, and a pressure chamber 58. The motor 511 is fixedly installed at the bottom of the cooling cylinder 1, and the motor 511 is fixed through its output shaft. A rotating shaft 51 is connected, which passes through and rotatably connects to the bottom of the cooling cylinder 1. A slider 52 is fixedly connected to the surface of the rotating shaft 51. The top of the lifting cylinder 53 is fixedly connected to the bottom of the drain filter cylinder 2. A sliding groove 54 is provided inside the lifting cylinder 53. Both the slider 52 and the sliding groove 54 are configured in two sets, and the two sets of sliders 52 are slidably connected in the two sets of sliding grooves 54 respectively. When the rotating shaft 51 rotates, it will drive the lifting cylinder 53 to rotate synchronously through the cooperation of the two sets of sliders 52 and the two sets of sliding grooves 54. A lifting plate 5 is fixedly connected to the surface of the lifting cylinder 53. 5. An annular groove 56 is provided inside the lifting plate 55. An eccentric plate 57 is fixedly connected to the surface of the rotating shaft 51. The air pressure chamber 58 passes through and is fixedly connected to the bottom of the cooling cylinder 1. An air bag 59 is provided at one end of the air pressure chamber 58. A piston rod A510 is slidably connected to the piston inside the other end of the air pressure chamber 58. The eccentric plate 57 and the side of the air bag 59 away from the air pressure chamber 58 are close together. The air bag 59 is initially in an inflated state. When the rotating shaft 51 drives the eccentric plate 57 to rotate, it will repeatedly squeeze the air bag 59, and the air pressure inside the air bag 59 will be compressed. The piston rod A510 moves upward through the air pressure chamber 58. A circular block 512 is fixedly connected to the end of the piston rod A510 away from the air pressure chamber 58. The circular block 512 is slidably connected in the annular groove 56. The weight of the drain filter 2 is greater than the friction between the slider 52 and the slide groove 54. The circular block 512 remains stationary under the restriction of the piston rod A510. The upward movement of the piston rod A510 will drive the lifting plate 55 to move upward through the circular block 512. The weight of the drain filter 2 can drive the slider 52 to move downward along the slide groove 54.

[0034] In this embodiment, the blanched green beans are placed in the drain filter cylinder 2, and an appropriate amount of cold water is added to the cooling cylinder 1. The motor 511 is turned on, and the motor 511 drives the rotating shaft 51 to rotate through its output shaft. The rotation of the rotating shaft 51 will drive the lifting cylinder 53 and the drain filter cylinder 2 to rotate synchronously through the cooperation of two sets of sliders 52 and two sets of sliding grooves 54. The rotation of the lifting cylinder 53 will drive the lifting plate 55 to rotate. The round block 512 will remain stationary under the restriction of the piston rod A510. The rotation of the rotating shaft 51 will also drive the eccentric plate 57 to rotate. The rotation of the eccentric plate 57 will repeatedly squeeze the air bag 59. The air bag 59 will be squeezed and the air pressure inside will enter the air pressure chamber 58, pushing the piston rod A510 to move upward. The upward movement of the cylinder 0 will cause the lifting plate 55 to move upward through the circular block 512. The upward movement of the lifting plate 55 will cause the lifting cylinder 53 and the drain filter cylinder 2 to move upward. When the eccentric plate 57 leaves the air bag 59, the lifting cylinder 53, the drain filter cylinder 2 and the lifting plate 55 will move downward due to gravity and return to their original positions. The piston rod A510 will move downward and return to its original positions. The air pressure will return to the air bag 59 and the air bag 59 will re-inflate, thus forming a cycle. During the rotation of the drain filter cylinder 2 and its repeated up and down movement, the green beans in the drain filter cylinder 2 can fully contact the cool water in the cooling cylinder 1, which will accelerate the cooling efficiency. When the water in the cooling cylinder 1 is drained, the rotation of the drain filter cylinder 2 and its repeated up and down movement can also speed up the draining of the green beans.

[0035] Example 2

[0036] like Figures 1-9As shown, based on the same concept as Embodiment 1 above, a second embodiment is also proposed. The water inlet mechanism 6 includes a rotating gear 61 and a pressure chamber 62. The rotating gear 61 is fixedly connected to the surface of the rotating shaft 51, and the pressure chamber 62 is fixedly connected to the bottom of the cooling cylinder 1. A return spring 63 is provided inside the pressure chamber 62. A piston rod B64 is slidably connected to the inside of the pressure chamber 62 through the return spring 63. A gear rack 65 is fixedly connected to the end of the piston rod B64 away from the pressure chamber 62. The rotating gear 61 is an incomplete gear, and the teeth on the gear rack 65 are matched with the teeth on the rotating gear 61. When the gear 61 rotates and its upper teeth mesh with the upper teeth of the rack 65, it will drive the rack 65 to move to the right. A water suction pipe 66 is fixedly connected to the bottom of the pressure chamber 62. The end of the water suction pipe 66 away from the pressure chamber 62 is fixedly connected to the bottom of the water tank 4. A water outlet pipe 67 is fixedly connected to the top of the pressure chamber 62. The end of the water outlet pipe 67 away from the pressure chamber 62 is fixedly connected to the side of the cooling cylinder 1. Both the water suction pipe 66 and the water outlet pipe 67 are equipped with one-way valves. The one-way valve in the water suction pipe 66 allows one-way flow into the pressure chamber 62, and the one-way valve in the water outlet pipe 67 allows one-way flow into the pressure chamber 62. The valve is unidirectionally openable towards the cooling cylinder 1. When a negative pressure is formed inside the pressure chamber 62, water from the water tank 4 is drawn into the pressure chamber 62 through the suction pipe 66. When the pressure chamber 62 is squeezed, the water inside is discharged through the outlet pipe 67. The metering drainage mechanism 7 includes a fixed ring 71, which is fixedly connected to the inside of the drain pipe 3. The fixed ring 71 has a long groove 72 inside, and a telescopic spring 73 is installed inside the long groove 72. A sliding block 74 is slidably connected inside the long groove 72 through the telescopic spring 73. A sliding rod 75 is fixedly connected to the bottom of the sliding block 74. The sliding rod 75 is away from the sliding block 74. One end of block 74 is fixedly connected to a closing block 76. The outer diameter of the closing block 76 is equal to the inner diameter of the fixing ring 71. In the initial state, one-third of the closing block 76 is located inside the fixing ring 71. The closing block 76 is stuck inside the fixing ring 71, preventing water in the cooling cylinder 1 from being discharged through the drain pipe 3. A pull rod 77 is fixedly connected to the bottom of the closing block 76. The elastic force of the telescopic spring 73 is greater than the weight of the closing block 76. The pull rod 77 passes through and slides through the bottom of the drain pipe 3. The closing block 76 can be pulled downward by the pull rod 77, while the elastic force of the telescopic spring 73 can drive the closing block 76 to move upward and return to its original position.

[0037] In this embodiment, while the motor 511 drives the rotating shaft 51 to rotate, causing the drain filter cartridge 2 to rotate and move up and down repeatedly, cold water can be added to the water tank 4. The rotation of the rotating shaft 51 drives the rotating gear 61 to rotate. When the upper teeth of the rotating gear 61 mesh with the upper teeth of the gear rod 65, the gear rod 65 moves to the right. The rightward movement of the gear rod 65 causes the piston rod B64 to move to the right, compressing the return spring 63. The rightward movement of the piston rod B64 squeezes the water in the pressure chamber 62, causing it to be discharged through the outlet pipe 67. When the rotating gear 61 rotates to the toothless part and disengages from the gear rod 65, the return spring 63 rebounds, causing the piston rod B64 and the gear rod 65 to move to the left to return to their original positions. At this time, a negative pressure is formed in the pressure chamber 62, drawing water from the water tank 4 through the suction pipe 66 to replenish the pressure chamber 62, thus forming a cycle. Cold water is then discharged through the outlet pipe 67 into the drain filter cartridge 2 to accelerate the growth of green beans. The cooling process is effective, preventing the water in the cooling cylinder 1 from heating up after contact with the green beans, which would otherwise reduce the cooling effect. As the water in the cooling cylinder 1 increases, the water pressure in the drain pipe 3 increases, causing the sealing block 76 to move downwards away from the fixing ring 71. The sliding rod 75 and the sliding block 74 move downwards, and the telescopic spring 73 is stretched. This ensures that the cool water in the cooling cylinder 1 is kept at a certain level, preventing the water level from being too high due to the water discharged from the outlet pipe 67, and preventing the cool water level in the cooling cylinder 1 from being too low due to the water draining too quickly from the drain pipe 3. This further improves the stability of the overall device. When the water in the water tank 4 is depleted and the water in the cooling cylinder 1 needs to be completely drained, pulling down the lever 77 can cause the sealing block 76 to move away from the fixing ring 71, allowing for complete drainage. When the lever 77 is released, the telescopic spring 73 causes the sliding block 74, the sliding rod 75, and the sealing block 76 to return to their original positions, resealing the drain pipe 3.

[0038] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
