Description

Technical Field

[0001] This invention relates to the field of goji berry processing technology, specifically a goji berry freshness-locking and drying device. Background Technology

[0002] Goji berries have high medicinal value and can be processed into goji berry polysaccharides. Goji berry polysaccharides are water-soluble polysaccharides and the most important active ingredients in goji berries. Among them, the immunomodulatory and anti-tumor effects of goji berry polysaccharides have been studied the most. Goji berries need to be dried during the production process. The drying process is usually carried out by vacuum drying equipment. Goji berries are placed on shelves, the shelves are moved into the drying chamber, and the freshness is locked in by vacuum heating.

[0003] To prevent dirt from the ground from entering the drying chamber, existing drying equipment typically does not have floor-mounted rollers on its shelves. This means that when moving the shelves in and out of the drying chamber, a trolley is needed to push them, or the shelves are installed inside the drying chamber via guide rails. This makes it difficult to move the shelves in and out. Furthermore, the mesh panels stacked directly inside the shelves are interconnected. In the early stages of drying, the moisture from the lower layer of goji berries rises and affects the upper layer, resulting in decreased drying efficiency, poor uniformity, and difficulty in quickly removing the mesh panels from the shelves. Summary of the Invention

[0004] The purpose of this invention is to provide a goji berry freshness-locking and drying device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A goji berry freshness-locking and drying device includes a drying chamber and a base at the bottom of the drying chamber, and further includes: The support assembly is located on one side of the base. The support assembly includes multiple U-shaped frames. Threaded sleeves are movably inserted into both ends of the U-shaped frames. Grounding rollers are symmetrically fixed at both ends of the lower surface of the U-shaped frames. The transmission component is located inside the U-shaped frame. A screw is symmetrically and rotatably connected inside the U-shaped frame, and the screw is screwed into a threaded sleeve at a corresponding position. A shelf is movable inside the drying chamber. The shelf includes a frame, and multiple crossbars are fixedly installed at equal intervals on the inner side of the frame. A placement component is disposed inside the frame. The placement component includes a heat-conducting plate fixedly installed between two crossbars at corresponding positions. A fixed frame is movably provided above the heat-conducting plate, and a mesh plate is fixedly installed on the inner surface of the fixed frame.

[0006] Furthermore, the lower surface of the frame is symmetrically provided with multiple connecting slots at equal intervals, and the threaded sleeve is movably inserted into the corresponding connecting slot.

[0007] Furthermore, multiple auxiliary wheels are equidistantly arranged at the bottom of the frame, and multiple sensor plates are connected to the bottom of the frame by studs. An infrared distance sensor is fixedly installed on the upper surface of the U-shaped frame by a bracket.

[0008] Furthermore, the U-shaped frame has symmetrically opened grooves inside, and the outer surface of the threaded sleeve has symmetrically fixed sliders, which are slidably connected to the grooves at the corresponding positions.

[0009] Furthermore, two connecting seats are fixedly installed on the upper surface of the base, and limit seats are fixedly installed on one side of the connecting seats and one side of the U-shaped frame. Limit rods are fixedly installed on the other side of the U-shaped frame. The limit rods are movably inserted into the limit seats at the corresponding positions, and electromagnets are fixedly embedded inside the limit seats.

[0010] Furthermore, the U-shaped frame is internally connected to a rotating shaft, with a first bevel gear fixedly installed at both ends of the shaft and at one end of the screw. The two first bevel gears at corresponding positions are connected by a moving meshing transmission.

[0011] Preferably, a motor is fixedly embedded in the upper surface of the U-shaped frame, and a second bevel gear is fixedly installed on the output end of the motor and the outer surface of the rotating shaft. The two second bevel gears are connected by movable meshing.

[0012] Furthermore, a first guide groove is provided on the lower surface of the heat-conducting plate, and multiple second guide grooves are provided at equal intervals on the lower surface of the heat-conducting plate. One end of each of the multiple second guide grooves is fixedly connected to the first guide groove. Insertion holes are provided at the four corners of the heat-conducting plate. Insert rods are fixedly installed at the four corners of one side surface of the fixing frame. The insert rods are movably inserted into the corresponding insertion holes, and limit plates are fixedly installed on the outer surface of the insert rods.

[0013] Preferably, the frame has multiple through slots inside and multiple square slots are equally spaced on the outer surface of the frame. The square slots are fixedly connected to the through slots at corresponding positions. A pull rod is slidably inserted into the through slot, and a connecting frame is fixedly connected to the upper end of the pull rod.

[0014] Preferably, multiple top rods are fixedly installed at equal intervals on the outer surface of the pull rod. The top rods slide through the square grooves at corresponding positions, and the top rods are movably inserted into the insertion holes at corresponding positions. A pad is connected to the upper end of the frame through a rope.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The distance between the distance sensing plates is sensed by an infrared distance sensor. When the corresponding infrared distance sensor senses the sensing plate at the corresponding distance, the signal from the infrared distance sensor is transmitted through an external PLC. After processing, the PLC causes the corresponding motor to execute the corresponding control command according to the set control logic.

[0016] 2. The motor operates, causing the threaded sleeve to move up and down, controlling the separation and connection of the grounding rollers with the shelf. By installing detachable grounding rollers at the bottom of the shelf, when the shelf is moved into the drying chamber, the grounding rollers separate from the shelf, and the shelf is supported by the slide rails inside the drying chamber. When the shelf is moved out of the drying chamber, the grounding rollers connect with the shelf to support it. This prevents dirt from the ground from entering the drying chamber and makes the shelf easier to move in and out of the drying chamber, making it more convenient to use.

[0017] 3. In the initial stage of drying, the moisture volatilized from the lower layer of goji berries is blocked by the upper heat-conducting plate, causing the water vapor to flow along the No. 1 and No. 2 guide channels to both sides of the heat-conducting plate. This prevents the lower layer water vapor from directly passing over the upper layer of goji berries, reducing the impact of the lower layer water vapor on the drying of the upper layer of goji berries, improving drying efficiency and the drying uniformity of goji berries at different heights. In addition, the No. 2 guide channel is inclined, which facilitates the water vapor to slide out along the No. 2 guide channel to both sides of the heat-conducting plate when the water vapor condenses at the bottom of the heat-conducting plate, reducing the impact of its condensation and dripping on the drying rate.

[0018] 4. Pull the connecting frame upwards to move the multiple connecting rods connected to it upwards, move the insert rod out of the insertion hole, place the pad between the upper end of the frame and the connecting frame to support the connecting frame, so that multiple fixed frames are all above the heat conduction plate, making it easy for people to pull them out directly from one side of the heat conduction plate, thus making it easy to quickly move the wire mesh and goji berries out of the shelf.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-9 In this embodiment of the invention, a goji berry freshness-locking drying device includes a drying chamber 1 and a base 101 at the bottom of the drying chamber 1, and also includes a support component 2 disposed on one side of the base 101. The support component 2 includes multiple U-shaped frames 202, with threaded sleeves 204 movably inserted into both ends of the U-shaped frames 202. Grounding rollers 203 are symmetrically fixedly installed at both ends of the lower surface of the U-shaped frames 202. A transmission component 3 is disposed inside the U-shaped frames 202, and screws 3 are symmetrically rotatably connected inside the U-shaped frames 202. 01, the screw 301 is screwed into the threaded sleeve 204 at the corresponding position. The shelf 4 is movably installed inside the drying chamber 1. The shelf 4 includes a frame 401. Multiple crossbars 402 are fixedly installed at equal intervals on the inner side of the frame 401. The placement component 5 is set inside the frame 401. The placement component 5 includes a heat-conducting plate 501 fixedly installed between two crossbars 402 at the corresponding position. A fixed frame 505 is movably provided above the heat-conducting plate 501. A mesh plate 508 is fixedly installed on the inner surface of the fixed frame 505.

[0023] Specifically, after the goji berries are placed inside the frame 401, they are moved into the drying chamber 1 by the support component 2. The threaded sleeve 204 is separated from the frame 401 by the transmission component 3. Then the door of the drying chamber 1 is closed, and the drying equipment is started to dry and preserve the goji berries inside the drying chamber 1. The goji berries are supported and placed by the placement component 5. The heat conduction plate 501 separates each layer of goji berries, reducing the impact of the lower layer of moisture on the drying rate of the upper layer of goji berries. After the shelf 4 is moved out, the top rod 407 is moved up by multiple pull rods 406, which simultaneously lifts multiple mesh plates 508 upwards, making it easy to remove the mesh plates 508 and the goji berries laid on them.

[0024] Example 1 like Figure 3-5 As shown, in this embodiment, a plurality of connecting slots 103 are symmetrically and evenly spaced on the lower surface of the frame 401, and the threaded sleeve 204 is movably inserted into the connecting slot 103 at the corresponding position; a plurality of auxiliary wheels 105 are evenly spaced at the bottom of the frame 401, and the auxiliary wheels 105 provide auxiliary support for the shelf 4 when the shelf 4 moves into the drying chamber 1 and connects with the slide rail inside it; a plurality of sensing plates 104 are screwed to the bottom of the frame 401 through studs; and an infrared distance sensor 209 is fixedly installed on the upper surface of the U-shaped frame 202 through a bracket.

[0025] In this embodiment, the infrared distance sensor 209 senses the distance between the distance sensing plates 104. When the corresponding infrared distance sensor 209 senses the sensing plate 104 at the corresponding distance, the signal of the infrared distance sensor 209 is transmitted through the external PLC. After processing, the PLC causes the corresponding motor 304 to execute the corresponding control command according to the set control logic.

[0026] like Figure 4 and Figure 5 As shown, in this embodiment, the U-shaped frame 202 has symmetrically opened sliding grooves 206 inside, and the outer surface of the threaded sleeve 204 is symmetrically fixedly installed with sliders 205, which are slidably connected to the sliding grooves 206 at the corresponding positions; the U-shaped frame 202 is rotatably connected with a rotating shaft 302, and a first bevel gear 303 is fixedly installed at both ends of the rotating shaft 302 and one end of the screw 301, and the two first bevel gears 303 at the corresponding positions are movably meshed and connected for transmission; a motor 304 is fixedly embedded in the upper surface of the U-shaped frame 202, and a second bevel gear 305 is fixedly installed at the output end of the motor 304 and the outer surface of the rotating shaft 302, and the two second bevel gears 305 are movably meshed and connected for transmission.

[0027] In practice, the motor 304 operates, and through the meshing transmission of the second bevel gear 305, the rotating shaft 302 rotates. Through the meshing transmission of the first bevel gear 303, the two screws 301 rotate. Through the screw 301 and the threaded sleeve 204, under the sliding limit of the slider 205 and the slide groove 206, the threaded sleeve 204 moves up and down, connecting and separating from the connecting groove 103. This controls the separation and connection of the grounding roller 203 with the shelf 4. Thus, by setting a separable grounding roller 203 at the bottom of the shelf 4, when the shelf 4 is moved into the drying chamber 1, the grounding roller 203 separates from the shelf 4, and the shelf 4 is supported by the slide rail inside the drying chamber 1. When the shelf 4 is moved out of the drying chamber 1, the grounding roller 203 connects to the shelf 4 to support the shelf 4. This avoids dirt from the ground entering the drying chamber 1 and makes the shelf 4 easy to move in and out of the drying chamber 1, making it more convenient to use.

[0028] like Figure 7 and Figure 9 As shown, in this embodiment, a first guide groove 502 is formed on the lower surface of the heat-conducting plate 501, and a plurality of second guide grooves 503 are formed at equal intervals on the lower surface of the heat-conducting plate 501. One end of each of the second guide grooves 503 is fixedly connected to the first guide groove 502. Insertion holes 504 are formed at the four corners of the heat-conducting plate 501. Insert rods 506 are fixedly installed at the four corners of one side surface of the fixing frame 505. The insertion rods 506 are movably inserted into the insertion holes 504 at the corresponding positions. The insertion holes 504 are used to limit the position of the insertion rods 506 and to position the fixing frame 505. Limiting pieces 507 are fixedly installed on the outer surface of the insertion rods 506.

[0029] In practice, the fixing frame 505 increases the stability of the mesh plate 508. After the goji berries are laid on top of the mesh plate 508, the fixing frame 505 is moved above the heat-conducting plate 501, aligning the insertion rods 506 at the four corners of the fixing frame 505 with the corresponding insertion holes 504. Under the action of gravity, the fixing frame 505 moves the insertion rods 506 downwards, inserting them into the corresponding insertion holes 504, thus fixing the fixing frame 505 and the mesh plate 508 inside the frame 401. This improves the stability of the mesh plate 508 when the shelf 4 moves, especially during the initial drying stage. During this period, the moisture volatilized from the lower layer of goji berries is blocked by the upper heat-conducting plate 501, causing the water vapor to flow along the first guide groove 502 and the second guide groove 503 to both sides of the heat-conducting plate 501. This prevents the lower layer water vapor from directly passing over the upper layer of goji berries, reducing the impact of the lower layer water vapor on the drying of the upper layer of goji berries, improving drying efficiency and the drying uniformity of goji berries at different heights. In addition, the second guide groove 503 is inclined, which facilitates the water vapor to slide out along the second guide groove 503 to both sides of the heat-conducting plate 501 when the water vapor condenses at the bottom of the heat-conducting plate 501, reducing the impact of its condensation and dripping on the drying rate.

[0030] like Figure 6-9As shown, in this embodiment, the frame 401 has multiple through slots 403 inside, and multiple square slots 404 are equally spaced on the outer surface of the frame 401. The square slots 404 are fixedly connected to the through slots 403 at corresponding positions. A pull rod 405 is slidably inserted into the through slot 403. The pull rod 405 is stored in the through slot 403, and the movement direction of the pull rod 405 is restricted, so that the pull rod 405 can move up and down in the vertical direction. A connecting frame 407 is fixedly connected to the upper end of the multiple pull rods 405. Multiple top rods 406 are fixedly installed at equal intervals on the outer surface of the pull rods 405. The top rods 406 slide through the square slots 404 at corresponding positions. The square slots 404 restrict the maximum upward and downward movement distance of the top rods 406 to prevent excessive upward movement, which would cause the fixed frame 505 to fall off the top of the heat conduction plate 501. The top rods 406 are movably inserted into the insertion holes 504 at corresponding positions. A pad 408 is connected to the upper end of the frame 401 by a rope.

[0031] In practice, when it is necessary to remove the wire mesh 508 and goji berries from the shelf 4, pull the connecting frame 407 upwards, causing multiple connecting rods 405 connected to it to move upwards inside the through groove 403, and then move the multiple connecting rods 405 upwards inside the square groove 404. At this time, the connecting rods 405 push the corresponding insertion rods 506, moving the insertion rods 506 out of the insertion holes 504. Then, the pad 408 is placed between the upper end of the frame 401 and the connecting frame 407 to support the connecting frame 407, so that the multiple fixed frames 505 are all above the heat conduction plate 501, making it easy for people to pull them out directly from one side of the heat conduction plate 501, thus making it easy to quickly remove the wire mesh 508 and goji berries from the shelf 4.

[0032] Example 2 Based on Embodiment 1, in order to solve the problem that it is not easy to fix the U-shaped frame 202 after it is separated from the shelf 4.

[0033] like Figure 3 As shown, in this embodiment, two connecting seats 201 are fixedly installed on the upper surface of the base 101. Limiting seats 207 are fixedly installed on one side surface of both the connecting seats 201 and the U-shaped frame 202. Limiting rods 208 are fixedly installed on the other side surface of the U-shaped frame 202. The limiting rods 208 are movably inserted into the limiting seats 207 at the corresponding positions. An electromagnet is fixedly embedded inside the limiting seats 207.

[0034] In practice, when the threaded sleeve 204 at a U-shaped frame 202 separates from the shelf 4, the corresponding limiting rod 208 is inserted into the corresponding limiting seat 207. The electromagnet works, attracting the iron limiting rod 208, thus fixing the corresponding U-shaped frame 202 and forming a whole with multiple U-shaped frames 202. Conversely, when the shelf 4 is moved out, the electromagnet is turned off, causing the U-shaped frame 202 to move with the shelf 4 and support the shelf 4.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
