Description

Technical Field

[0001] The invention relates to the technical field of vacuum drying devices, and in particular to a vacuum drying device for seafood based on the coupling of microwaves and dehydration membranes. Background Art

[0002] Microwave vacuum dryer combines microwaves with vacuum. While the microwaves dry the materials inside, the vacuum environment also reduces the boiling point of water in the materials, making it easier to evaporate the moisture in the materials. At the same time, under vacuum conditions, microwaves can penetrate the materials more effectively and accelerate the evaporation of water. Therefore, it is widely used in the fields of seafood drying, vegetable drying, medicinal material drying, chemical product drying, and electronic component drying.

[0003] In the process of using the existing vacuum dryer, a dehydration film is usually covered on the surface of the material, and then the material covered with the dehydration film is placed in the container of the dryer. The dehydration film first absorbs the moisture in the material to reduce the pollution of the moisture in the material to the inside of the dryer, while increasing the specific surface area of ​​the material, shortening the time required for material drying, and also playing a certain moisturizing role on the material to avoid cracking of the surface of the material after drying. However, when drying the material, most of the evaporated moisture comes from the inside of the material. At this time, regardless of whether the dehydration film is used, part of the material will stick to the surface of the container during the drying process, making it more difficult to separate the material from the container later, and then making the material more susceptible to damage during separation, affecting the quality of the material.

DETAILED DESCRIPTION

[0044] The present invention will now be described more fully below with reference to the accompanying drawings, in which currently preferred embodiments of the present invention are shown. However, the present invention can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

[0045] like Figure 1-Figure 9 As shown, the present invention proposes a vacuum drying device for seafood based on the coupling of microwave and dehydration membrane, which is used for dehydrating and drying materials to be dried. The vacuum drying device for seafood based on the coupling of microwave and dehydration membrane comprises: a drying shell 1, the drying shell 1 is externally connected to a vacuum pump, the vacuum pump is an existing device, which is not shown in the figure, and its working process is not described in detail in the text; a heating shell 2, which is installed inside the drying shell 1; a mounting plate 3, which has two symmetrically distributed plates on the left and right, both of which are slidably connected to the inside of the heating shell 2, and the lower sides of the two mounting plates 3 are rotatably connected to a driving shaft 4, and the drying shell 1 is provided with a driving module for driving the driving shaft 4 to rotate, wherein the driving module is an existing device, which is not shown in the figure, and its working process is not described in detail in the text, and the upper sides of the two mounting plates 3 are rotatably connected to a driven shaft; the driven shaft on the mounting plate 3 and the driving shaft 4 are jointly provided with a transmission member 5, and the transmission member 5 rotates counterclockwise (with a rotation direction of 1 / 2) when rotating. Figure 2 The perspective from left to right in the figure is the reference perspective); a connecting shell 21 is rotatably connected between the two transmission members 5, an upper dehydration membrane is detachably connected to the upper side of the connecting shell 21, a moving shell 7 is slidably connected inside the connecting shell 21, a lower dehydration membrane 8 is fixedly connected to the lower side of the moving shell 7, and the moving shell 7 and the lower dehydration membrane 8 cooperate with each other to store materials; a supporting assembly is arranged in the heating shell 2, and the supporting assembly is used to support the lower dehydration membrane 8.

[0046] In the above scheme, in order to reduce the friction between the two mounting plates 3 and the heating shell 2, rolling wheels can be installed at the positions where the two mounting plates 3 contact the heating shell 2 to convert the sliding friction between the two into rolling friction. The transmission member 5 can be selected as a chain or a belt. The specific selection can be made by the staff according to the specific working environment. At the same time, when selecting the transmission member 5, the parts connecting the transmission member 5 with the driving shaft 4 and the two driven shafts should also be specifically adjusted. The specific number of connecting shells 21 can be specifically selected by the staff during use, and it is not specifically mentioned in the text. At the same time, a connecting shell 21 is used as an example for description in the text. The lower dehydration membrane 8 is composed of a selective semipermeable membrane, a high osmotic pressure food and a polymer absorbent, which is used to absorb the moisture in the material, increase the specific surface area of ​​the material, thereby increasing the drying speed of the material, and moisturizing the surface of the material. The material and function of the upper dehydration membrane are the same as the material and function of the lower dehydration membrane 8. The upper dehydration membrane is not initially installed on the connecting shell 21. After placing the material to be dried, the upper dehydration membrane is installed on the connecting shell 21 by the staff. At the same time, in order to ensure that the upper dehydration membrane can be in close contact with the material, it is necessary to place a sufficient amount of material in the movable shell 7 (even if the upper side of the material should be higher than the upper side of the movable shell 7).

[0047] Furthermore, the supporting component includes: an extrusion shell 22, which is arranged on the movable shell 7, the lower dehydration membrane 8 is located in the adjacent extrusion shell 22, and the lower dehydration membrane 8 is in contact with the extrusion shell 22 to support the lower dehydration membrane 8, and the extrusion shell 22 is slidably connected to the connecting shell 21; a first connecting block 23, which is arranged on the extrusion shell 22, and a tension spring is fixedly connected between the first connecting block 23 and the connecting shell 21 to drive the first connecting block 23 to reset; a trigger component, which is arranged on one side of the mounting plate 3, and the trigger component is used to change the relative position of the movable shell 7 and the connecting shell 21.

[0048] In the above scheme, the extrusion shell 22 is used to provide support force for the adjacent lower dehydration membrane 8. The first connection block 23 is fixedly connected to the adjacent extrusion shell 22, and the first connection block 23 drives the adjacent moving shell 7 to move synchronously through the adjacent extrusion shell 22. The tension spring between the first connection block 23 and the adjacent connection shell 21 is used to maintain the initial position of the extrusion shell 22 and drive the adjacent extrusion shell 22 to reset.

[0049] Furthermore, the trigger assembly includes: a first guide block 31, which is fixed to the front side of the right mounting plate 3, and the mounting plate 3 is fixed with a second guide block 32; a first extrusion block 33, the number of which is consistent with the number of the connecting shells 21, and both are fixed to the right side of the adjacent extrusion shell 22 through a connecting rod, and the first extrusion block 33 and the first guide block 31 and the second guide block 32 are all limited and extruded, and a gap is provided between the first guide block 31 and the second guide block 32 for the connecting rod on the first extrusion block 33 to pass through, so that the connecting rod on the first extrusion block 33 can pass smoothly.

[0050] In the above scheme, the distance between the first guide block 31 and the second guide block 32 is smaller than the length of the longest side of the first extrusion block 33, and the extrusion shell 22 drives the adjacent first extrusion blocks 33 to move synchronously through the connecting rod. After the first extrusion block 33 moves to the front side, the extrusion shell 22 drives the adjacent first extrusion block 33 to move upward, and the first extrusion block 33 will contact the first guide block 31 and the second guide block 32, thereby being deformed by the common extrusion force of the first guide block 31 and the second guide block 32. When the first extrusion block 33 is deformed, its front and rear sides bend downward.

[0051] Furthermore, the first extrusion block 33 is made of rubber material, so that the first extrusion block 33 can be deformed smoothly under the joint extrusion of the first guide block 31 and the second guide block 32. The elastic coefficient of the first extrusion block 33 is greater than the elastic coefficient of the tension spring between the first connecting block 23 and the adjacent connecting shell 21. When the first extrusion block 33 contacts the first guide block 31 and the second guide block 32, the first extrusion block 33 stops moving, and then the first extrusion block 33 drives the extrusion shell 22 to move downward synchronously relative to the connecting shell 21 through the connecting rod, stretching the tension spring between the adjacent first connecting block 23 and the adjacent connecting shell 21, and the projection of the first extrusion block 33 on the mounting plate 3 is an isosceles obtuse triangle, which is used to reduce the resistance encountered by the two acute-angled parts of the first extrusion block 33 when they are deformed.

[0052] In the above scheme, the obtuse angle of the first extrusion block 33 is located on the upper side, and its lower side is parallel to the horizontal plane. At the same time, the inclined surfaces on the front and rear sides are set as friction surfaces. The front inclined surface is extruded and matched with the second guide block 32, and the rear inclined surface is extruded and matched with the first guide block 31.

[0053] Furthermore, a rough surface is provided on one side of the first guide block 31 and the second guide block 32 that are extruded and matched with the first extrusion block 33, so as to increase the friction between the two and the first extrusion block 33. At the same time, the friction between the two and the first extrusion block 33 is greater than the tension of the tension spring between the adjacent first connecting block 23 and the adjacent connecting shell 21, so as to avoid the first connecting block 23 being reset upward under the action of the tension spring when the first extrusion block 33 contacts with the first guide block 31 and the second guide block 32.

[0054] When using the device to dry materials at low temperature, it is necessary to first pull out the two mounting plates 3, and add a sufficient amount of materials into all the moving shells 7 in turn (at this time, the upper surface of the materials is higher than the upper side of the moving shells 7), and then the staff will cover all the materials with the upper dehydration film, and use the existing device to fix the upper dehydration film and the adjacent connecting shell 21. After fixation, the upper dehydration film is supported by the protruding materials to form a curved surface. The staff will push the two mounting plates 3 into the heating shell 2, and start the vacuum pump and the microwave heating device to reduce the air pressure in the drying shell 1 while also using microwaves to bake the materials at low temperature, so as to dry the materials. Drying treatment: After the upper dehydration film is covered, the upper dehydration film cooperates with the adjacent lower dehydration film 8 to absorb the moisture contained in the material in the adjacent moving shell 7, increase the specific surface area of ​​the material in the moving shell 7, and then increase the drying speed of the material in the moving shell 7. At the same time, the upper dehydration film and the adjacent lower dehydration film 8 cooperate with each other to moisturize the upper and lower surfaces of the material in the moving shell 7 respectively, to avoid cracking of the upper and lower layers of the material in the moving shell 7 during the drying process, affecting the quality of the material after drying. While starting the vacuum pump and the microwave heating device, the staff starts the driving module, and the driving module drives the driving shaft 4 to rotate.

[0055] During the rotation of the driving shaft 4, the driving shaft 4 cooperates with the two driven shafts to drive the two transmission members 5 to rotate synchronously, and then the two transmission members 5 cooperate with each other to drive all the connecting shells 21 to move counterclockwise synchronously (with Figure 3 The perspective of the connecting shell 21 is taken as the reference perspective) to continuously change the relative positions of all the connecting shells 21. Meanwhile, during the rotation process, the connecting shell 21 is affected by gravity and continuously rotates relative to the two transmission members 5. Even if the connecting shell 21 is continuously moving with the two transmission members 5, the lower side of the connecting shell 21 is always kept parallel to the horizontal plane. The following is a description of the movement process of one of the connecting shells 21 as an example:

[0056] During the process of the connection shell 21 rotating with the two transmission members 5, until the connection shell 21 rotates to the front side, the connection shell 21 is driven by the two transmission members 5 to move upward (by Figure 1The front angle of view is the reference angle. At this time, the connecting shell 21 is located at the lowest side of the front side. Therefore, the movement process of the connecting shell 21 at the lower side is described below). Until the first extrusion block 33 at the lower front side moves upward to contact the opposite sides of the first guide block 31 and the second guide block 32, the first guide block 31 and the second guide block 32 jointly squeeze the first extrusion block 33, so that the first extrusion block 33 is deformed by the extrusion force. At the same time, the first extrusion block 33 stops moving upward when it is subjected to the extrusion force, and then the first extrusion block 33 drives the extrusion shell 22 to gradually move downward through the adjacent connecting rod. The extrusion shell 22 drives the moving shell 7 and the lower dehydration membrane 8 to move downward synchronously relative to the connecting shell 21, increasing the distance between the lower dehydration membrane 8 and the upper dehydration membrane, and separating the material in the moving shell 7 from the adjacent upper dehydration membrane. At the same time, in the process of the extrusion shell 22 moving downward relative to the connecting shell 21, the extrusion shell 22 drives the first connecting block 23 at the lower front side to move downward synchronously, and causes the tension spring between the first connecting block 23 and the connecting shell 21 to be stretched and stored.

[0057] Until the above-mentioned extrusion shell 22 moves downward to the limit position, the tension spring between the first connecting block 23 and the connecting shell 21 is synchronously stretched to the limit state. At this time, the connecting shell 21 can continue to drive the first extrusion block 33 to move upward in the gap between the first guide block 31 and the second guide block 32, until the first extrusion block 33 moves upward to lose contact with the first guide block 31 and the second guide block 32 (at this time, the first extrusion block 33 moves upward to the uppermost side of the front side), the first extrusion block 33 returns to its initial state, and at the same time, the tension spring on the connecting shell 21 drives the first connecting block 23 and the extrusion shell 22 to reset upward synchronously, thereby loosening the material in the moving shell 7 due to vibration, thereby preventing the material in the moving shell 7 from sticking due to the loss of liquid during the drying process, affecting the shape and quality of the material after drying.

[0058] The movement process of the remaining connecting shells 21 can refer to the above. After the material is dried, the staff pulls out the two mounting plates 3 and takes out the dried materials in all the moving shells 7 in turn. Then, the next batch of materials to be dried is placed in all the moving shells 7 in turn, and the above steps are repeated to dry the next batch of materials.

[0059] Furthermore, Figure 2-Figure 7As shown, it also includes a material turning mechanism, which is arranged in the heating shell 2 and is used to change the position of the material. The material turning mechanism includes: bidirectional screws 40, the number of which is consistent with the number of connecting shells 21, and are rotatably connected to adjacent connecting shells 21 through connecting pieces; driving gears 41, the number of which is consistent with the number of bidirectional screws 40, and are respectively fixed to one end of the adjacent bidirectional screws 40 close to the first guide block 31, the first guide block 31 is provided with a toothed groove, the teeth in the toothed groove of the first guide block 31 mesh with the adjacent driving gear 41, and are used to drive the adjacent bidirectional screws 40 to rotate; guide rods 42, the number of which is consistent with the number of bidirectional screws 40, are respectively fixed to the connecting pieces of the adjacent bidirectional screws 40, the guide rods 42 are slidably connected to the second connecting block 421, the second connecting block 421 is fixedly connected to the second extrusion block 43, the extrusion shell 22 is provided with a slide groove that slidably cooperates with the adjacent second extrusion block 43, and the second connecting block 421 is threadedly connected to the adjacent bidirectional screw 40.

[0060] In the above scheme, after the driving gear 41 contacts the gear groove on the first guide block 31, the driving gear 41 will drive the adjacent bidirectional screw 40 to rotate and then drive the second extrusion block 43 to move. When the bidirectional screw 40 just starts to rotate, the second extrusion block 43 moves to the left. When the bidirectional screw 40 moves upward to the middle of the first guide block 31, the second extrusion block 43 moves to the left to the limit position. Then, when the bidirectional screw 40 continues to move upward, the adjacent second extrusion block 43 starts to reset to the right. When the bidirectional screw 40 moves upward to separate from the first guide block 31, the second extrusion block 43 resets to the initial position. The guide rod 42 is used to maintain the adjacent second extrusion block 43 in a vertical state to prevent the second extrusion block 43 from rotating circumferentially with the adjacent bidirectional screw 40. During the movement of the second extrusion block 43, the adjacent lower dehydration film 8 moves in a wave-like manner.

[0061] Furthermore, the driving gear 41 and the adjacent first extrusion block 33 are spaced unequally from the same mounting plate 3 , so as to avoid the first extrusion block 33 affecting the rotation of the driving gear 41 .

[0062] In the above scheme, the driving gear 41 is arranged on the left side of the adjacent first extrusion block 33, so that the driving gear 41 and the adjacent first extrusion block 33 are staggered in the vertical plane, thereby preventing the first extrusion block 33 from colliding with the adjacent driving gear 41 after deformation, thereby affecting the normal rotation of the driving gear 41.

[0063] Furthermore, the maximum length of the tension spring between the first connecting block 23 and the adjacent connecting shell 21 is equal to the height difference between the lower side surface inside the adjacent extrusion shell 22 and the lower side surface of the adjacent second extrusion block 43 .

[0064] In the above scheme, after the tension spring between the first connecting block 23 and the adjacent connecting shell 21 is stretched to the maximum length, the lower side surface of the second extrusion block 43 is just located on the lower side surface inside the adjacent connecting shell 21, and the two are in contact with each other, so that the second extrusion block 43 can move along the lower side surface inside the adjacent extrusion shell 22 during the lateral movement, thereby preventing the second extrusion block 43 from squeezing the adjacent lower dehydration membrane 8 between the second extrusion block 43 and the extrusion shell 22 during the movement, so as to prevent the adjacent lower dehydration membrane 8 from being damaged by the extrusion force and affecting the normal use of the adjacent lower dehydration membrane 8.

[0065] During the downward movement of the above-mentioned front lower extrusion shell 22, the second extrusion block 43 is gradually inserted into the slide groove of the extrusion shell 22. As the downward movement distance of the extrusion shell 22 increases, the volume of the second extrusion block 43 located in the extrusion shell 22 also increases continuously. Until the extrusion shell 22 moves downward to the limit position, the lower side surface of the second extrusion block 43 is located on the upper side of the lower side surface inside the extrusion shell 22, and the two are tightly fitted. At this time, the upper side of the second extrusion block 43 squeezes the lower dehydration film 8 on the front lower side, causing the lower dehydration film 8 to deform due to the extrusion force, thereby changing the distribution state of the material in the lower dehydration film 8, until the front lower driving gear 41 moves upward to contact the tooth groove on the first guide block 31, while the front lower connecting shell 21 drives the driving gear 41 to continue to move upward, the front lower driving gear 41 drives the front lower bidirectional screw 40 to rotate, and then the bidirectional screw 40 drives the second extrusion block 43 to move left and right through the second connecting block 421.

[0066] When the second extrusion block 43 on the front lower side moves left and right, the contact position of the second extrusion block 43 and the lower dehydration membrane 8 is constantly changing, thereby causing the upward protrusion position of the lower dehydration membrane 8 to constantly change, that is, in the process of the second extrusion block 43 moving left and right, the lower dehydration membrane 8 moves in a wave-like manner, thereby constantly changing the distribution state of the material in the lower dehydration membrane 8, so that the material in the lower dehydration membrane 8 is pushed by the second extrusion block 43 and continuously flows, that is, the material in the lower dehydration membrane 8 is turned over, so that the material in the lower dehydration membrane 8 is separated, and the material is also separated from the lower dehydration membrane 8, so as to avoid the material from sticking to the dehydration membrane.

[0067] The driving gear 41 stops rotating until the front lower driving gear 41 moves upward and loses contact with the first guide block 31. At this time, the second extrusion block 43 moves to the initial position. The movement process of the driving gear 41 at other positions can refer to the above process and will not be described in detail.

[0068] Furthermore, if Figure 4 and Fig. 9As shown, it also includes cleaning components that are distributed at intervals. The cleaning components that are distributed at intervals are all arranged in the heating shell 2. The number of cleaning components is consistent with the number of connecting shells 21. The cleaning components are used to clean the upper dehydration film on the adjacent connecting shells 21. The cleaning components include: a connecting plate 51, which is fixed to one side of the adjacent second connecting block 421, and the connecting plate 51 is fixed with a cleaner 52; a limiting groove 53, which is opened on the adjacent connecting shell 21, and the cleaner 52 passes through the adjacent limiting groove 53. The cleaner 52 is slidably connected to the adjacent connecting shell 21, and the cleaner 52 is in contact with the upper dehydration film on the adjacent connecting shell 21.

[0069] In the above scheme, in order to increase the stability of the cleaner 52 during lateral movement, two connecting plates 51 are set to be symmetrically distributed front and back, and the positions where the cleaner 52 is fixed to the two connecting plates 51 are selected to be rigid materials, and the part in contact with the upper dehydration membrane on the adjacent connecting shell 21 can be selected to be a flexible material (such as a steel wire rope).

[0070] During the movement of the above-mentioned second extrusion block 43 on the front lower side, the second extrusion block 43 on the front lower side drives the adjacent cleaner 52 to move synchronously through the two connecting plates 51 thereon, and the front lower side cleaner 52 scrapes the material sticking to the lower side of the upper dehydration membrane on the front lower side connecting shell 21 during the movement, so that the material sticking to the lower side of the upper dehydration membrane on the front lower side connecting shell 21 is separated therefrom, and even if the material sticking to the lower side of the upper dehydration membrane of the connecting shell 21 falls into the movable shell 7 on the front lower side, it is prevented that the material adheres to the lower side of the upper dehydration membrane on the connecting shell 21 after drying, which increases the difficulty of separating the material from the dehydration membrane in the subsequent process, thereby causing the material to be more easily damaged when separated from the dehydration membrane, resulting in the quality and quality of the material after drying being affected.

[0071] When the second extrusion block 43 on the front lower side is reset to the initial position, the cleaner 52 on the front lower side is reset to the initial position synchronously for subsequent use. The movement process of the cleaner 52 at other positions can refer to the above process and will not be described in detail.

[0072] The above description is only an example of the present invention and is not intended to limit the present invention. Any equivalent substitutions made within the principles of the present invention should be included in the protection scope of the present invention. The contents not elaborated in detail in the present invention belong to the existing technologies known to those skilled in the art.
