Description

Technical Field

[0001] This utility model relates to the field of freeze-drying production technology, and in particular to a freeze-dried bird's nest production device. Background Technology

[0002] Freeze-dried bird's nest production equipment is a technological device that enables the low-temperature freeze-drying of bird's nest, preserving its nutritional components and natural form. It typically includes a pre-treatment auxiliary module, a freeze-drying main unit, a vacuum system, a refrigeration system, and an intelligent temperature control unit. During production, the bird's nest raw materials, after being cleaned and trimmed, are first loaded onto trays through the pre-treatment module and then sent into the sealed freeze-drying main unit cavity. The refrigeration system is activated first, rapidly lowering the temperature of the bird's nest within the cavity. A low-pressure environment is then maintained, causing the ice crystals in the low-temperature bird's nest to sublimate directly into water vapor. This water vapor is then captured by the condensation system, ultimately resulting in a freeze-dried bird's nest product that retains its nutritional value and is easy to store. However, most current freeze-dried bird's nest production equipment still suffers from insufficient automation, especially in the unloading process, which often relies on manual labor. After freeze-drying, trays containing the freeze-dried bird's nests must be manually removed from the low-temperature freeze-drying unit one by one, and the products must be sorted. This process is not only repetitive and tedious, slowing down overall production efficiency, but the trays are also made of 304 stainless steel and are quite heavy. Slight carelessness when moving the trays from a height during unloading could cause them to fall, posing a safety hazard. Therefore, the freeze-drying production technology field needs to develop a freeze-dried bird's nest production device that can improve automation, thereby enhancing operational convenience and reducing safety risks. Utility Model Content

[0003] In view of the above-mentioned prior art, the present invention provides a freeze-dried bird's nest production device, which mainly solves the technical problem of how to improve the degree of automation, thereby improving the ease of operation and reducing safety risks.

[0004] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows: A freeze-dried bird's nest production apparatus includes a freeze dryer body, a tray, and a freeze-drying chamber. A support plate is provided inside the freeze-drying chamber, and a transport frame is provided below the tray. The tray and the transport frame are detachably connected to each other, and the transport frame is detachably connected to the support plate. A pushing mechanism is provided inside the freeze-drying chamber for pushing the transport frame to separate from the support plate. The transport frame includes a connecting rod, an L-shaped support frame, and rolling wheels. The L-shaped support frame is symmetrically arranged on both sides of the tray, and the rolling wheels are located at the bottom of the L-shaped support frame. The L-shaped support frames are fixedly connected to each other through the connecting rod. A slit is provided in the middle of the support plate.

[0005] Preferably, a sealing door is provided on one side of the freeze dryer body, one side of the sealing door is hinged to the freeze dryer body, a handle is provided on one side of the sealing door, and the side of the sealing door not hinged to the freeze dryer body is connected to the freeze dryer body through a locking mechanism.

[0006] Preferably, the locking mechanism includes a first connecting seat, a threaded rod, a threaded sleeve, a limiting ring, a rotating rod, a second connecting seat, and a limiting groove. The first connecting seat is fixedly connected to the freeze dryer body, the threaded rod is hinged to the connecting seat, the threaded sleeve is threadedly connected to the threaded rod, the limiting ring is fixedly connected to the threaded sleeve, the rotating rod is fixedly connected to the side of the threaded sleeve away from the threaded rod, the second connecting seat is fixedly connected to the sealing door, and the limiting groove is fixedly connected to the second connecting seat.

[0011] Preferably, the actuation mechanism includes an electrically telescopic rod.

[0012] Preferably, a transport vehicle is provided on one side of the freeze dryer body, and a track adapted to the transport vehicle is provided below the transport vehicle.

[0013] The beneficial effects of this utility model are as follows: This application sets up a transport rack for storing multiple pallets at the same time, and uses an L-shaped support frame to support the bottom of the pallets, so that a certain gap can be left when the bottom of the pallet contacts the support plate, making the temperature change of the pallet more stable during the freeze-drying process and improving the reliability of the device. At the same time, a pushing mechanism is set on the inside of the freeze-drying chamber, which can push out the transport rack so that the pallets on the transport rack can be sent out together, without the need for operators to take out the pallets one by one. The bottom of the L-shaped support frame is also equipped with rollers, making the transport rack smoother when pushed out by the pushing mechanism.

[0014] In summary, by using a transport frame and support plate in conjunction, this application can effectively improve the ease of material unloading and reduce safety risks. Attached Figure Description

[0018] Example 1 See attached document Figure 1-7 This application provides a freeze-dried bird's nest production apparatus, including a freeze dryer body 1, a tray 2, and a freeze-drying chamber 3. A support plate 301 is provided inside the freeze-drying chamber 3. A transport frame 4 is provided below the tray 2. The tray 2 and the transport frame 4 are detachably connected to each other. The transport frame 4 is detachably connected to the support plate 301. A pushing mechanism is provided inside the freeze-drying chamber 3. The pushing mechanism is used to push the transport frame 4 to separate from the support plate 301. The transport frame 4 includes a connecting rod 401, an L-shaped support frame 402, and rolling wheels 403. The L-shaped support frame 402 is symmetrically arranged on both sides of the tray 2. The rolling wheels 403 are arranged at the bottom of the L-shaped support frame 402. The L-shaped support frame 402 is fixedly connected to each other through the connecting rod 401. A slit 302 is provided in the middle of the support plate 301. This device uses a transport frame 4 to simultaneously store multiple pallets 2, and an L-shaped support frame 402 to support the bottom of the pallets 2. This allows for a certain gap when the bottom of the pallet 2 contacts the support plate 301, resulting in more stable temperature changes during the freeze-drying process and improving the reliability of the device. Simultaneously, a pushing mechanism is provided inside the freeze-drying chamber 3 to push out the transport frame 4, facilitating the delivery of the pallets 2 on top of the transport frame 4 without requiring operators to remove each pallet 2 individually. The bottom of the L-shaped support frame 402 is also equipped with rollers, making the push of the transport frame 4 smoother. In this embodiment, the operator can move a trolley or mobile platform outside the freeze-drying chamber 3. After the pushing mechanism pushes the transport frame 4 and pallets 2 together from behind the support plate 301, the trolley or mobile platform is used to receive them and transport them to subsequent operating equipment. In summary, this device, through the combination of the transport frame 4 and the support plate 301, effectively improves the ease of unloading and reduces safety risks.

[0019] Specifically, a sealing door 101 is provided on one side of the freeze dryer body 1. One side of the sealing door 101 is hinged to the freeze dryer body 1, and a handle 102 is provided on one side of the sealing door 101. The side of the sealing door 101 not hinged to the freeze dryer body 1 is connected to the freeze dryer body 1 through a locking mechanism 103. This device, by setting the locking mechanism 103 in conjunction with the sealing door 101, can seal or open the freeze drying chamber 3 as needed.

[0020] Specifically, the locking mechanism 103 includes a first connecting seat 104, a threaded rod 105, a threaded sleeve 106, a limiting ring 107, a rotating rod 108, a second connecting seat 109, and a limiting groove 110. The first connecting seat 104 is fixedly connected to the freeze dryer body 1. The threaded rod 105 is hinged to the connecting seat. The threaded sleeve 106 is threadedly connected to the threaded rod 105. The limiting ring 107 is fixedly connected to the threaded sleeve 106. The rotating rod 108 is fixedly connected to the side of the threaded sleeve 106 away from the threaded rod 105. The second connecting seat 109 is fixedly connected to the sealing door 101. The limiting groove 110 is fixedly connected to the second connecting seat 109. When the freeze-drying chamber 3 needs to be sealed, the sealing door 101 closes, the threaded rod 105 rotates around the first connecting seat 104, so that the limiting ring 107 on the threaded sleeve 106 connected to it fits into the limiting groove 110, and the rotating rod 108 fixedly connected to the threaded sleeve 106 rotates, so that the limiting ring 107 moves toward the first connecting seat 104, pressing the limiting groove 110, thereby making the sealing door 101 fit tightly against the freeze dryer body 1, achieving the sealing purpose.

[0021] Specifically, the sealing door 101 is provided with an observation window 111 in the middle, which allows the operator to easily observe the freeze-drying state of the bird's nest in the freeze-drying chamber 3.

[0022] Specifically, a sealing ring 113 is provided on the side of the freeze dryer body 1 near the sealing door 101. The sealing ring 113 can improve the sealing performance of the sealing door 101 and ensure that the freeze drying chamber 3 can be reliably sealed when cooling and depressurizing.

[0023] Specifically, a liquid collection tank 112 is provided at the bottom of the freeze dryer body 1, and the liquid collection tank 112 is detachably connected to the freeze dryer body 1. The liquid collection tank 112 can collect water flowing out of the freeze drying chamber 3, avoiding affecting the working environment.

[0024] Specifically, the L-shaped support frame 402 has blocking bars 404 on opposite sides, and the L-shaped support frame 402 and the blocking bars 404 form a rectangular structure adapted to the tray 2. The blocking bars 404 can prevent the tray 2 from sliding off from the sides of the L-shaped support frame 402.

[0025] Specifically, the pushing mechanism includes an electrically operated telescopic rod. One side of the electric telescopic rod is attached to the transport frame 4, and the other side is located inside the freeze-drying chamber 3. Under the control of the control system, the transport frame 4 can be fully extended, thereby facilitating subsequent processing.

[0026] Example 2 See attached document Figure 8 The difference between this embodiment and Embodiment 1 is that a transport vehicle 5 is provided on one side of the freeze dryer body 1, and a track 502 adapted to the transport vehicle 5 is provided below the transport vehicle 5. The transport vehicle 5 can carry the transport rack 4 and the pallet 2 for transportation without the operator having direct contact with the pallet 2 and the transport rack 4. In this embodiment, the bottom of the transport vehicle 5 is equipped with a control motor 501 and wheels 503. After the control system controls the sealing door 101 to open, the transport vehicle 5 moves along the track 502 to one side of the freeze-drying chamber 3 under the control of the control motor 501 to receive the transport frame 4 and the tray 2. After the transport vehicle 5 has moved, the control system controls the pushing mechanism to push out the transport frame 4 and the tray 2. The transport vehicle 5 receives the transport frame 4 and the tray 2 and moves the transport frame 4 and the tray 2 under the control of the control system. In this embodiment, the control system is set to an 8051 microcontroller. It should be understood that the control system can also be set to any control system commonly used in the art, which can meet the needs of this application. At the same time, in this embodiment, an electromagnet 504 is also provided on the transport vehicle 5, and the transport frame 4 is made of magnetic metal. After the tray 2 is pushed out, the control system controls the electromagnet 504 to be energized to attract the transport frame 4 and prevent the transport frame 4 from sliding and falling during transportation.
