Description

Technical Field

[0001] This utility model relates to a dehydration device, specifically a low-temperature vacuum dehydration device for seaweed, belonging to the field of seaweed processing technology. Background Technology

[0002] Water hyacinth, commonly known as "water hyacinth," is a perennial submerged herbaceous plant belonging to the genus *Hydrocharitaceae* in the family Hydrocharitaceae. It is endemic to China, primarily found in Yunnan Province, where it is a local specialty ingredient. It is rich in nutrients and has cooling, detoxifying, diuretic, and swelling-reducing effects. Dehydration reduces the water content of the water hyacinth, extending its shelf life and facilitating transportation and storage. Dehydrated water hyacinth also has a crisper texture and less nutrient loss, making it more suitable for subsequent cooking. A dehydration device is required during the dehydration process.

[0003] According to patent CN213848538U, a low-temperature vacuum dehydration device is disclosed, which includes a tank, a heating and circulation system, a rotary stirring mechanism, a vacuum system, and a cooling system. The tank has an inlet and an outlet. The heating and circulation system includes a hot water jacket set in the tank, and the hot water forms an internal circulation in the hot water jacket.

[0004] The above-mentioned solution has the advantages of low environmental pollution, saving space and time, simple structure and low processing cost. However, it is inconvenient to dry the seaweed evenly during the implementation of the above-mentioned solution. The seaweed near the drying area is dried more thoroughly, while the seaweed far away from the drying area is difficult to dry effectively, which affects the final dehydration effect. To this end, we provide a low temperature vacuum dehydration device for seaweed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a low-temperature vacuum dehydration device for seaweed flowers to solve the above-mentioned problems, thereby addressing the issue in the prior art that it is difficult to ensure uniform drying of seaweed flowers in all locations.

[0006] This utility model is achieved through the following technical solution: a low-temperature vacuum dehydration device for seaweed, comprising a vacuum dehydrator, a sealing door hinged to the outer surface of the vacuum dehydrator, a support cylinder fixedly connected to the inner bottom wall of the vacuum dehydrator, a bearing plate movably connected inside the support cylinder, a dehydration cylinder inserted inside the support cylinder, a transmission mechanism for driving the bearing plate being provided inside the support cylinder, the transmission mechanism comprising a transmission column and a driven sleeve, a set of support rods fixedly connected to the bottom surface of the bearing plate, a ball bearing being rotatably installed at the bottom end of each support rod, and a set of lifting blocks fixedly connected to the inner bottom wall of the support cylinder.

[0007] Preferably, the transmission column passes through the support cylinder and is rotatably connected to the support cylinder, the driven sleeve is fixed to the bottom surface of the bearing plate, the transmission column slides inside the driven sleeve, and the transmission column plays the role of driving the driven sleeve to rotate.

[0008] Preferably, the inner bottom wall of the support cylinder is provided with a rolling groove, and both the lifting block and the rolling groove are adapted to the ball bearings. The lifting block drives the ball bearings to move up and down.

[0009] Preferably, two limiting slide rods are fixedly connected to the outer surface of the transmission column, and two sliding grooves adapted to the limiting slide rods are opened inside the driven sleeve. Each limiting slide rod slides in the corresponding sliding groove. The limiting slide rods are used to ensure that the driven sleeve and the transmission column rotate synchronously.

[0010] Preferably, a worm gear is fixedly connected to the bottom surface of the transmission column, and a worm is rotatably connected inside the vacuum dehydrator. The worm gear meshes with the worm, and the worm gear provides power for the transmission mechanism.

[0013] This utility model provides a low-temperature vacuum dehydration device for seaweed flowers, which has the following beneficial effects: This application incorporates components such as a support cylinder, a bearing plate, a dehydration cylinder, and a transmission mechanism.

[0017] This utility model provides a low-temperature vacuum dehydration device for seaweed.

[0018] Please see Figure 1 and Figure 2 The process for low-temperature vacuum dehydration of seaweed, including vacuum dehydrator 1, generally involves: washing, slicing, quick-freezing, and vacuum drying. The quick-freezing process involves rapidly freezing the seaweed to completely crystallize its internal water, and then sending it to vacuum dehydrator 1 for sublimation. Vacuum dehydrator 1 can directly sublimate the ice crystals through its internal heating components and discharge them through vacuum pump 10, thereby achieving dehydration of the seaweed and facilitating the preservation and transportation of the dehydrated seaweed. The structural components shown in the accompanying drawings are illustrative examples. The specific implementation should be adapted and optimized based on the functional requirements, assembly conditions, and process limitations of the actual application scenario, including structural parameters, dimensions, and connection methods.

[0019] A vacuum pump 10 is fixedly installed on the top surface of the vacuum dehydrator 1, and a temperature controller 11 is fixedly installed inside the sealed door 2. The vacuum pump 10 can perform vacuuming on the vacuum dehydrator 1, maintaining a vacuum state inside the vacuum dehydrator 1. It can also extract the water vapor generated by sublimation, preventing water vapor from accumulating in the vacuum dehydrator 1 and affecting its operation. At the same time, it can also prevent water vapor from corroding the dehydrated vegetables, ensuring the dehydration effect of the device. The temperature controller 11 allows the operator to easily control the heating temperature in the vacuum dehydrator 1. During vacuum drying and dehydration, the vacuum level in the vacuum dehydrator 1 needs to be controlled to be lower than the triple point pressure of water, i.e., 4.6 mmHg / 610 Pa, to ensure that the ice crystals sublimate directly. The temperature is controlled between -25℃ and 0℃ to ensure the sublimation of the ice crystals and to prevent the collapse of the dried layer. After sublimation, the temperature controller 11 readjusts the internal temperature of the vacuum dehydrator 1 to 30-40℃ to remove the bound water. The heating components, servo motor 9 and vacuum pump 10 inside the vacuum dehydrator 1 are all existing technologies and will not be described in detail in this application.

[0020] Please see Figure 2 and Figure 3 The outer surface of the vacuum dehydrator 1 is hinged with a sealing door 2. A support cylinder 3 is fixedly connected to the inner bottom wall of the vacuum dehydrator 1. A bearing plate 4 is movably connected inside the support cylinder 3. A dehydration cylinder 5 is inserted inside the support cylinder 3. The sealing door 2 and the vacuum dehydrator 1 have good sealing performance, which can ensure the vacuum state of the vacuum dehydrator 1. The support cylinder 3 is used to support the placement of the dehydration cylinder 5. The dehydration cylinder 5 is used to hold the seaweed raw material after low temperature freezing. The outer wall of the dehydration cylinder 5 has a mesh with a certain aperture, which can facilitate the device to heat and sublimate the seaweed raw material inside. The bearing plate 4 is used to support the dehydration cylinder 5 and can drive the dehydration cylinder 5 to rotate through the transmission mechanism 6, so that the seaweed raw material in the dehydration cylinder 5 can get a more uniform heating effect during the dehydration process, improving the dehydration effect of the device. After the operator puts the dehydration cylinder 5 into the support cylinder 3, the device can be started to carry out vacuum dehydration operation.

[0021] A worm gear 7 is fixedly connected to the bottom surface of the transmission column 601. A worm 8 is rotatably connected inside the vacuum dewatering machine 1. The worm gear 7 meshes with the worm 8. The rotation of the worm 8 can drive the worm gear 7 to rotate inside the vacuum dewatering machine 1. The rotation of the worm gear 7 can drive the transmission column 601 to rotate. The rotation of the transmission column 601 can drive the bearing plate 4 to rotate in the support cylinder 3, thereby driving the dewatering cylinder 5 to rotate. This facilitates the device to perform uniform dewatering of the seaweed. The top surface of the bearing plate 4 is treated with friction texture to increase the friction between it and the dewatering cylinder 5, so that the bearing plate 4 can drive the dewatering cylinder 5 to rotate during low-speed rotation.

[0022] Please see Figure 1 , Figure 2and Figure 3 A servo motor 9 is fixedly installed on the outside of the vacuum dehydrator 1. The worm 8 is fixedly connected to the output shaft of the servo motor 9. The servo motor 9 provides power for the rotation of the worm 8. When the servo motor 9 starts, it can drive the worm 8 to rotate inside the vacuum dehydrator 1. The rotation of the worm 8 can drive the worm wheel 7 to rotate through meshing, thereby providing power for the operation of the transmission mechanism 6. When the servo motor 9 is in use, its rotation speed is set to be low to ensure that the bearing plate 4 can stably drive the dehydration cylinder 5 to rotate.

[0023] Please see Figure 4 The support cylinder 3 is equipped with a transmission mechanism 6 that drives the bearing plate 4. The transmission mechanism 6 includes a transmission column 601 and a driven sleeve 602. The transmission column 601 passes through the support cylinder 3 and is rotatably connected to the support cylinder 3. The driven sleeve 602 is fixed to the bottom surface of the bearing plate 4. The transmission column 601 slides inside the driven sleeve 602. The rotation of the transmission column 601 can drive the bearing plate 4 to rotate through the driven sleeve 602. Under the action of the ball bearing 604 and the lifting block 605, the rotation of the driven sleeve 602 will drive the bearing plate 4 to rotate and rise synchronously inside the support cylinder 3, so that the seaweed in the dehydration cylinder 5 can vibrate to a certain extent, and avoid the seaweed raw material at the center of the dehydration cylinder 5 from reducing the dehydration effect of the device due to pressure accumulation.

[0024] A set of support rods 603 are fixedly connected to the bottom surface of the support plate 4. Each support rod 603 has a ball bearing 604 rotatably mounted at its bottom end. A set of lifting blocks 605 are fixedly connected to the inner bottom wall of the support cylinder 3. A rolling groove 606 is formed on the inner bottom wall of the support cylinder 3. Both the lifting blocks 605 and the rolling groove 606 are adapted to the ball bearing 604. When the support plate 4 rotates within the support cylinder 3, it drives the support rods 603 to rotate. The rotation of the support rods 603 causes the ball bearing 604 to slide in the rolling groove 606. When the ball bearing 604 contacts the lifting block 605, it rises along the lifting block 605 and falls at the other end, thereby causing the support plate 4 to slide up and down inside the support cylinder 3. The sliding of the support plate 4 drives the dehydration cylinder 5 to rise and fall, thus improving the heating and dehydration effect of the seaweed raw material in the dehydration cylinder 5. The ball bearing 604 reduces friction and prevents obstruction to the rotation of the support plate 4.

[0025] Two limiting slide rods 607 are fixedly connected to the outer surface of the transmission column 601. Two sliding grooves adapted to the limiting slide rods 607 are opened inside the driven sleeve 602. Each limiting slide rod 607 slides in the corresponding sliding groove. The limiting slide rods 607 and sliding grooves are designed to ensure that the driven sleeve 602 can rotate with the rotation of the transmission column 601 and to provide a certain degree of limiting effect for the lifting and lowering of the driven sleeve 602, thereby improving the transmission stability of the transmission mechanism 6.

[0026] Working principle: During use, the operator first places the dehydration cylinder 5 containing the seaweed raw material into the support cylinder 3, then closes the sealing door 2, and controls the operation of the vacuum pump 10 and heating components through the temperature controller 11. Finally, the servo motor 9 is started. The vacuum pump 10 extracts air from the vacuum dehydrator 1, creating a vacuum inside. The heating components regulate the temperature inside the vacuum dehydrator 1, causing the ice crystals in the seaweed to sublimate directly. The servo motor 9 drives the worm gear 8 to rotate in the vacuum dehydrator 1. The rotation of the worm gear 8 drives the worm wheel 7 to rotate through meshing. The rotation of the worm wheel 7 drives the transmission column 601 to rotate in the support cylinder 3. The rotation of 601 can drive the driven sleeve 602 to rotate through the limiting slide rod 607 and the slide groove. The rotation of the driven sleeve 602 drives the bearing plate 4 to rotate, thereby causing the dehydration cylinder 5 to rotate slowly inside the vacuum dehydrator 1. This allows the seaweed in the dehydration cylinder 5 to be heated evenly. At the same time, the rotation of the bearing plate 4 can also drive the ball bearing 604 to rotate. When the ball bearing 604 rotates to contact the lifting block 605, it will move up and down along the lifting block 605, thereby pushing the bearing plate 4 to move up and down in the support cylinder 3. The movement of the bearing plate 4 can cause the seaweed in the dehydration cylinder 5 to vibrate, thereby preventing the seaweed in the center of the dehydration cylinder 5 from clumping and improving the dehydration effect of the device on the seaweed.
