Description

Technical Field

[0001] The invention belongs to the technical field of vegetable processing, and in particular relates to a dehydration device and a dehydration method for dried vegetable products. Background Art

[0002] At present, there are two common types of dried vegetables on the market: dried vegetables that are cut into pieces and then dehydrated, and dried vegetables that are pickled and then dehydrated. In comparison, the latter has a longer shelf life, tastes better, and retains the original shape of the vegetables, making them more ornamental.

[0003] Regardless of the type of dried vegetables, the commonly used dehydration methods include natural air drying, press dehydration, baking and drying. Natural air drying and drying take a long time and consume less energy; baking takes a short time but consumes more energy; press dehydration takes less time and consumes less energy, but it is difficult to handle the whole vegetable, and it is easy to form lumps and difficult to unload.

[0004] Authorization announcement number CN211334720U discloses a vegetable squeezing and dehydrating machine, which can lift the squeezed vegetables to the upper opening of the squeezing barrel, making it easy to take out the vegetables and avoid manually picking out the vegetables piece by piece. However, the device needs to take and put the squeezing barrel when unloading, which is inefficient and requires more manual operation.

[0005] In summary, the choice of dehydration method directly affects the quality and processing cost of dried vegetables. The processing of whole vegetables adds additional difficulty, which requires the improvement of traditional press dehydrators to improve their automation and continuous production capacity. Summary of the invention

[0006] In view of the above problems, the present invention provides a dehydration device for dried vegetable products. By improving the structure of the filter barrel and setting a transfer mechanism and a discharge mechanism, the automatic operation of the filter barrel is realized, thereby improving the work efficiency of vegetable processing.

[0007] One of the invention objects of the present invention is achieved through the following technical scheme: a dehydration device for dried vegetable products, comprising a device frame, a pressing mechanism in the form of downward pressing installed in the middle of the device frame, a pressing station is located directly below the pressing mechanism in the device frame, and a loading and unloading station is symmetrically arranged on both sides with the pressing station as the center, the pressing mechanism comprises a pressing container, the pressing container comprises a filter barrel and a barrel seat, the filter barrel has a hollow structure and side wall filter holes that pass through from top to bottom, the filter barrel as a whole is composed of a plurality of detachable petals, each of two adjacent petals is hinged at the upper opening, and the lower opening is in an open state, the barrel seat is used to support the filter barrel, and has an upper open section and a lower closed door;

[0008] The device also includes a transfer mechanism installed on the device frame for transferring the pressing container between the loading and unloading station and the pressing station, and a discharge mechanism installed on the device frame for lifting the filter barrel;

[0009] The transfer mechanism is used to transfer the filter barrel between the loading and unloading station and the pressing station;

[0010] The unloading mechanism is used to lift the filter barrel. After the filter barrel is lifted, the lower end thereof is opened, and the vegetable pieces are loosened and fall from the closed door into the aggregate container in the platform.

[0011] During operation, the pressing container is at the loading and unloading station, the closed door is closed, a certain amount of vegetables to be squeezed and dehydrated are put into the filter barrel, and the transfer mechanism transfers the pressing container to the bottom of the pressing mechanism. The pressing mechanism presses down to squeeze the vegetables in the filter barrel, and the moisture of the vegetables is discharged through the filter barrel. After squeezing is completed, the transfer mechanism moves the pressing container to the loading and unloading station, the closed door is opened, and the unloading mechanism lifts the filter barrel. When the filter barrel is lifted to the bottom and reaches the open section, the lower end of the filter barrel gets an open space, and the squeezed shape of the vegetables inside the filter barrel is released. The vegetables fall from the closed door and are received by the aggregate container.

[0012] Preferably, the transport mechanism includes: a guide rail, which is arranged on the outer wall of the filter barrel and the barrel seat; a driving wheel, which can slide and roll in contact with the guide; an elastic telescopic rod, one end of which is fixedly connected to the driving wheel; a rotating mounting seat, which is used to fix the end of the elastic telescopic rod; a walking track, which is used to support the movement of the barrel seat; a limiting wheel, which is arranged on the caster of the barrel seat; and a baffle, which is arranged on the walking track, which is used to limit the movement range of the barrel seat on the walking track.

[0013] This technical solution adopts guide rails, drive wheels, elastic telescopic rods, rotating mounting seats and other components to realize automatic movement of the filter barrel and the barrel seat. This setting automates the movement of the filter barrel and the barrel seat, which is a significant improvement over the existing technical solutions that require manual push to move the filter barrel and the barrel seat. In addition, the limiting wheels and baffles are used to limit the movement range of the barrel seat on the walking track. This setting ensures the stability and accuracy of the barrel seat movement process.

[0014] Preferably, the unloading mechanism includes: a lifting assembly; a working platform, the lifting and lowering of which is controlled by the lifting assembly; a cantilever, both ends of which are fixedly mounted on the working platform; a gripper, fixedly mounted on one end of the cantilever; a drive rod, horizontally fixedly mounted on the other end of the cantilever; and a contact slope, arranged at the lowest end of the lifting assembly, for driving the cantilever to retract.

[0015] The technical solution adopts a lifting component and a working platform to realize automatic lifting of the filter barrel. This setting automates the lifting operation of the filter barrel. The technical solution is provided with a cantilever, a gripper and a drive rod for grabbing and lifting the filter barrel. This setting makes the grabbing and lifting of the filter barrel more stable. The technical solution is provided with a contact slope for driving the cantilever to retract. This setting ensures the automatic retraction of the cantilever after the filter barrel is lifted.

[0016] Preferably, the filter barrel is provided with a limit piece attached to the caster, one end of the limit piece is sleeved in the caster, and the other end is sleeved through the mounting seat, and the mounting seat is provided with a waist hole at the sleeve position for the limit piece to move along the direction of the outward expansion of the petals of the filter barrel.

[0017] The technical solution is provided with a limiter and a mounting seat attached to the caster, which are used to limit the opening range of the filter barrel flap. This arrangement ensures the accuracy of the filter barrel flap opening process and prevents excessive opening.

[0018] Preferably, the gripper is configured to have a smooth transition with an arc at the bottom.

[0019] The technical solution sets the bottom of the gripper to be a smooth transition of an arc, which allows the gripper to fall from above the filter barrel and slide with the filter barrel as the gripper moves until the grip is completed. In this way, the lifting component can prepare materials or do other work for the vacant loading and unloading stations, that is, the gripper can complete the work that needs to be stopped at a high place.

[0020] Preferably, one side of the closed door is hinged to the barrel seat, and the opening and closing structure of the closed door includes: a fixed track, which is arranged in the device frame; an opening and closing roller, which can slide on the fixed track, and the lower surface of the closed door is against the surface of the opening and closing roller; a driving cylinder, which is used to drive the opening and closing roller to move to open or close the closed door.

[0021] The technical solution sets one side of the closed door to be hinged with the barrel seat. This setting enables the closed door to be opened and closed flexibly, thereby achieving effective closure or opening of the contents of the filter barrel. A fixed track, an opening and closing roller and a driving cylinder are provided to drive the automatic opening and closing of the closed door. This setting automates the opening and closing operation of the closed door. The working method of the technical solution is to drive the opening and closing roller to slide on the fixed track through the driving cylinder, and drive the closed door to open and close. This working method realizes the automation of the opening and closing operation of the closed door. The weight of the material is supported by the opening and closing roller under the closed door, and the support reliability is very high. In addition, the opening and closing of the closed door can be controlled by only driving the cylinder, and the opening and closing roller is supported at any opening angle.

[0022] Preferably, the gripper is designed to be provided with a roller at the position where the upper portion contacts the mounting seat, and the bottom surface of the mounting seat near the filter barrel is an upwardly inclined surface.

[0023] Preferably, the filter barrel is configured as a hollow double-layer structure.

[0024] The present invention also provides a dehydration method using the above dehydration device, the steps are:

[0025] S1. Place the processed vegetable material into the filter barrel at the loading and unloading station, and start the closing door to close the bottom of the filter barrel;

[0026] S2. Start the transfer mechanism to move the loaded filter barrel to the pressing station, which is located directly below the pressing mechanism; another filter barrel comes to the loading and unloading station, and the processed vegetable material is placed in the filter barrel;

[0027] S3. Start the pressing mechanism to apply pressure to the filter material by pressing down to remove the water in the filter material; the water flows out from the hollow structure of the filter barrel and the filter holes on the side wall, and finally gathers and flows out of the device;

[0028] S4. When the preset squeezing time or pressure is reached, the squeezing mechanism is stopped and the pressure is released;

[0029] S5. Start the transfer mechanism to move the filter barrel that has completed pressing to the loading and unloading station; open the closed door and open the filter barrel; at the same time, another filter barrel has been moved to the pressing station and is ready for pressing;

[0030] S6. At the loading and unloading station, start the unloading mechanism, grab and lift the filter barrel with the gripper, and drop the dehydrated vegetable material into the aggregate container;

[0031] S7. Retract the gripper and proceed to step to step to complete the batch continuous vegetable dehydration production;

[0032] S8. The vegetable materials in the aggregate container are dried, packaged and processed into dried vegetable products.

[0033] In summary, the present invention has the following advantages compared with the prior art:

[0034] 1. The technical solution of the present invention adopts a filter barrel with a hollow structure that passes through from top to bottom and filter holes on the side walls, and the filter barrel as a whole is composed of at least two detachable petals, each of which is hinged at the upper opening and the lower opening is open. This structure allows good ventilation during the dehydration process, is conducive to the circulation and escape of water, and is an improvement over the existing completely closed filter barrel structure.

[0035] 2. The technical solution of the present invention is provided with a transfer mechanism for transferring the filter barrel between the pressing station and the loading and unloading station, and a discharge mechanism for lifting the filter barrel. This arrangement makes the movement and operation of the filter barrel more convenient and faster, which is an improvement over the existing technical solution that requires manual operation.

[0036] 3. When the dehydration device of the present invention is working, the filter barrel is transferred to the bottom of the pressing mechanism for pressing by the transfer mechanism, and then the filter barrel is transferred to the loading and unloading station by the transfer mechanism after pressing, and the filter barrel is lifted by the unloading mechanism. After the filter barrel is lifted, the lower end thereof obtains an open space, and the vegetable blocks are loosened and fall from the closed door. This working mode realizes the automatic falling and unloading of the vegetable blocks in the filter barrel, which is a significant improvement over the existing technical solution that requires manual removal of the vegetable blocks from the filter barrel.

[0037] It should be pointed out that the design of the squeezing container of the present invention, the tall filter barrel and the short barrel seat, is designed based on the concept of utilizing the squeezing characteristics of the squeezing mechanism, that is, the pressure is concentrated on the lower part of the filter barrel. This type of filter barrel and barrel seat design can absorb the squeezing pressure by the surrounding support of the barrel seat, and then utilize the expandable structure at the bottom of the filter barrel to unload the material after lifting the filter barrel. After unloading is completed, the filter barrel can be automatically reset by simply lowering it.

[0038] Compared with the existing technology, the design concept of this filter barrel and barrel seat realizes the stability of the pressing container when it is subjected to greater pressure, as well as the rapid unloading and effective sealing of materials. This shows that the present invention has strong innovation in structural design, and the technical effect achieved is to improve the pressing efficiency and work efficiency.

DETAILED DESCRIPTION

[0048] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0049] Example 1

[0050] like Figure 1-Figure 3 As shown, the present invention relates to a dehydration device for dried vegetable products. The device is improved on the basis of CN211334720U, and has improved automation and continuous production capacity.

[0051] The device of the present invention includes a platform 10 with two material receiving stations, a device frame 20 installed on the platform 10, and a pressing mechanism 30 in the middle of the device frame 20. The pressing station is located directly below the pressing mechanism 30 in the device frame 20, and a loading and unloading station is symmetrically arranged on both sides with the pressing station as the center. The pressing mechanism 30 includes a pressing container 31, and the pressing container 31 includes a filter barrel 311 and a barrel seat 312. The filter barrel 311 has a hollow structure that passes through the top and bottom and side wall filter holes. The filter barrel 311 is composed of a plurality of detachable petals. Each adjacent two petals are hinged at the upper opening, and the lower opening is in an open state. The barrel seat 312 is used to support the filter barrel 311, and has an upper open section 01 and a lower closed door 02.

[0052] The device of the present invention further comprises a transfer mechanism 40 disposed on the device frame 20 for transferring the pressing container 31 between the loading and unloading station and the pressing station, and a discharge mechanism 50 installed on the device frame 20 for lifting the filter barrel 311 .

[0053] The transfer mechanism 40 is used to transfer the filter barrel 311 between the loading and unloading station and the pressing station. The power source can be a cylinder, a winch or a crawler to push or pull the barrel seat to complete the transfer; (the cylinder, winch or crawler is not shown in the figure);

[0054] The unloading mechanism 50 is used to lift the filter barrel 311, and a power source such as a cylinder or a winch can also be used to lift the filter barrel (the cylinder and the winch are not shown in the drawings). After the filter barrel is lifted, the lower end thereof is opened, and the vegetable pieces are loosened and fall from the closed door into the aggregate container in the platform.

[0055] During operation, the pressing container 31 is at the loading and unloading station, and the closed door 02 is closed. A certain amount of vegetables to be squeezed and dehydrated are put into the filter barrel 311, and the transfer mechanism 40 transfers the pressing container 31 to the bottom of the pressing mechanism 30. The pressing mechanism 30 presses down to squeeze the vegetables in the filter barrel 311, and the moisture of the vegetables is discharged through the filter barrel 311. After squeezing is completed, the transfer mechanism 40 moves the pressing container 31 to the loading and unloading station, and the closed door 02 is opened. At this time, the vegetables in the filter barrel 311 are squeezed into blocks and difficult to fall. The unloading mechanism 50 lifts the filter barrel 311. When the filter barrel 311 is lifted to the bottom and reaches the position of the open section 01, the lower end of the filter barrel 311 obtains an open space, and the squeezed shape of the vegetables inside the filter barrel 311 is released. The vegetables fall from the closed door 02 and are received by a receiving container placed on the platform 10.

[0056] In order to improve production efficiency, two sets of squeezing containers 31 are set. When one set is squeezing, the other set is unloading and loading to speed up the overall operation. Based on this design concept, the transfer mechanism 40 refers to Figure 2 , Figure 5 , Figure 6 Designed to include:

[0057] 1. A guide rail 60 of the same size is axially arranged on the outer wall of each filter barrel 311 and barrel seat 312. When the filter barrel 311 and barrel seat 312 are combined, the two guide rails 60 are combined and aligned and connected;

[0058] 2. A driving wheel 61 matched with each assembled guide rail 60 and an elastic telescopic rod 62 whose end is fixedly connected to the driving wheel 61;

[0059] 3. A rotating mounting seat 621 is provided for fixing and connecting the end of the elastic telescopic rod 62, and components and a power source for providing transmission connection for the rotating mounting seat 621;

[0060] 4. The bucket seat 312 is provided with a high and elastic caster 63 and a running track 64 matching the caster 63. At the same time, a limiting wheel 631 is provided on the caster 63, and a baffle 632 covering the limiting wheel 631 is provided in the entire range of the running track 64 to limit the movement of the bucket seat 312 within the translation range. The limiting wheel 631 and the caster 63 can absorb angular force and unbalanced force;

[0061] 5. The filter barrel 311 is provided with a stopper 65 attached to the caster 63 to prevent the filter barrel 311 from rotating relative to the barrel seat 312. One end of the stopper 65 is sleeved in the caster 63, and the other end is sleeved through the mounting seat 66. After the overall installation, the filter barrel 311 cannot rotate relative to the barrel seat 312, so as to ensure that the two sections of the guide rail 60 are aligned. The structure of the mounting seat 66 is Figure 7 It can be seen that the sleeve position is provided with a waist hole in the direction of the outward expansion of the petals of the filter barrel 311, so the assembly and installation of the stopper 65 will not limit the outward expansion of the petals of the filter barrel 311;

[0062] When the rotating mounting seat 621 is driven to rotate, the elastic telescopic rod 62 is driven to rotate, and the driving wheel 61 rolls in contact with the guide rail 60, so that the barrel seat 312 moves along the travel track 64. The rotating mounting seat 621 synchronously drives the two elastic telescopic rods 62, so that the two barrel seats 312 move synchronously and the moving distance is the same. Since the mounting seat 63 drives the two telescopic rods 62 to move synchronously when rotating, the two barrel seats 312 move synchronously and the moving distance is the same. On this basis, the pressing mechanism 30 and the unloading mechanism 50 can be set in a fixed position, and the setting becomes relatively simple.

[0063] The conventional design of the unloading mechanism 50 generally requires two steps of grabbing and lifting, and these two steps generally require two power systems and transmission components to cooperate to complete. In order to optimize the device, a unloading mechanism 50 is set on the side of the device frame 20 corresponding to each loading and unloading station. Figure 2 , Figure 4 , Figure 7 , Figure 8 Designed to include:

[0064] 1. A lifting assembly 51, a work platform 52 whose lifting is controlled by the lifting assembly 51, a cantilever 53 elastically slidably mounted in the work platform 52 is symmetrically arranged with the central axis of the filter barrel 311, a gripper 54 fixedly mounted at one end of each cantilever 53 away from the work platform 52, and a retracting drive rod 55 horizontally fixedly mounted at the other end of the cantilever 53; Figure 2 The gripper 54 is designed to extend into the bottom of the mounting seat 66, and apply force at the bottom of the mounting seat 66 to lift the filter barrel 311;

[0065] 2. A contact slope 56 cooperating with the driving rod 55 is fixedly arranged at the lowest point of the lifting assembly 51 and directly below the cantilever 53. When the working platform 52 descends to the point where the driving rod 55 contacts the contact slope 56, the cantilever 53 overcomes the elastic displacement and retracts, so as to avoid interference caused by the rotation of the elastic telescopic rod 62;

[0066] 3. The gripper 54 is designed to have a smooth transition with an arc at the bottom, so that when the cantilever 53 stops at a high position, the gripper 54 can also be lowered to contact the upper part of the mounting seat 66. Under the elastic contraction of the cantilever 53, the gripper 54 can also enter the bottom of the mounting seat 66. In this way, the lifting assembly 51 can prepare materials or do other work for the vacant loading and unloading stations, that is, the gripper 54 needs to stop at a high position for the operation;

[0067] 4. Reference Figure 7 The gripper 54 is designed to be provided with a roller 541 at the position where the upper part contacts the mounting seat 66, and the bottom surface of the mounting seat 66 near the filter barrel 311 is an upward inclined surface. When the roller 541 contacts the inclined surface and lifts up, the bottom of the corresponding petal of the filter barrel 311 generates outward expansion tension, which is conducive to the filter barrel 311 to open quickly when entering the open section 01, and will not be unable to open in time due to the adhesion and adsorption force generated by the squeezing of the dried vegetables.

[0068] This design adopts an elastic cantilever and a gripper to realize automatic grasping and lifting of the filter barrel 311, and considering the interference with other components and the opening of the filter barrel 311, further sets the contact cooperation between the roller 541 and the inclined surface to promote rapid unloading.

[0069] Reference Figure 3 and Figure 8 In order to simplify the opening and closing of the closed door 02 and improve the support reliability of the closed door 02, the opening and closing structure of the closed door 02 is designed to include: a fixed track 70 fixed in the device frame 20, an opening and closing roller 71 sliding along the fixed track 70, and a driving cylinder 72 driving the opening and closing roller 71 to move; the closed door 02 is hinged to the barrel seat 312 on one side close to the center of the device frame 20, and the lower surface of the closed door 02 is abutted against the outer surface of the opening and closing roller 71. When the opening and closing roller 71 is pushed out, the outer surface of the opening and closing roller 71 closes the closed door 02. When the filter barrel 311 is loaded with materials, the weight of the materials is supported by the opening and closing roller 71 under the closed door 02. The support reliability is very high, and the opening and closing of the closed door 02 can be controlled by only driving the cylinder 72, and the opening and closing roller 71 is supported at any opening angle.

[0070] This design adopts an opening and closing roller 71 and a driving cylinder 72 to replace a single hinge to realize the automatic opening and closing of the closed door 02, and takes the support of the material weight into consideration.

[0071] In order to improve the filtration and separation effect, it is convenient to collect the squeezed water. Figure 2 The filter barrel 311 is configured as a hollow double-layer structure, and the squeezed water is collected and flows out from the hollow position of the double-layer structure.

[0072] The dehydration method and steps of dried vegetable products are as follows:

[0073] 1. Put the processed vegetable material into the filter barrel 311 at the loading and unloading station, and start the closing door 02 to close the bottom of the filter barrel 311.

[0074] 2. Start the transfer mechanism 40 to move the loaded filter barrel 311 to the pressing station, which is located directly below the pressing mechanism 30. The other filter barrel 311 comes to the loading and unloading station, and the processed vegetable material is placed in the filter barrel 311.

[0075] 3. Start the pressing mechanism 30 to apply pressure to the filter material by pressing down to remove the water in the filter material. The water flows out from the hollow structure and the filter holes on the side wall of the filter barrel 311, and finally gathers and flows out of the device.

[0076] 4. When the preset squeezing time or pressure is reached, the squeezing mechanism 30 is stopped and the pressure is released.

[0077] 5. Start the transfer mechanism 40 to move the filter barrel 311 that has completed squeezing to the loading and unloading station. Open the closed door 02, and the filter barrel 311 is open. At the same time, another filter barrel 311 has been moved to the squeezing station and is ready for squeezing.

[0078] 6. At the loading and unloading station, start the unloading mechanism 50, grab and lift the filter barrel 311 through the gripper 54, and let the dehydrated vegetable material fall and pour it into the collection container.

[0079] 7. Retract the gripper 54. Continue with steps 1 to 6 to complete the batch continuous vegetable dehydration production.

[0080] 8. The vegetable materials in the aggregate container are dried, packaged and other subsequent processes to be made into dried vegetable products.

[0081] The dehydration method uses the filter barrel 311 to continuously squeeze, move and discharge under the drive of the squeezing mechanism 30, the transfer mechanism 40 and the unloading mechanism 50, and cooperates with the closed door 02 to realize automatic control, so as to realize efficient and continuous production. At the same time, the double-layer filter barrel 311 and the collecting hopper 08 are also used to collect and dehydrate, which is more reasonable than the previous method.
