Description

Technical Field

[0001] This utility model belongs to the field of fruit processing technology, and specifically relates to a freeze dryer for durian shells with a support component. Background Technology

[0002] A freeze dryer is a device that uses the principle of vacuum freeze drying to dehydrate materials. It first freezes the material into a solid state, and then vacuums the environment in which the material is located. The ice crystals in the material sublimate into a gaseous state, thus achieving the purpose of removing water. Durian shells contain rich trace elements and active proteins, and have high medicinal value. When extracting this medicinal part, a freeze dryer is needed to process the durian shells.

[0003] The patent specification with publication number CN217058177U discloses a freeze dryer with a support assembly, including a freeze dryer body, a support platform slidably connected inside the freeze dryer body, a base provided on the bottom wall of the freeze dryer body, a turntable rotatably mounted on the top of the base, an extension arm extending outward from the edge of the turntable, a protrusion provided on the top surface of the extension arm near its end, and a waist-shaped guide ring provided on the bottom surface of the support platform, a guide groove provided on the inner side of the guide ring, and the protrusion inserted into the guide groove;

[0004] In operation, this type of freeze dryer uses a motor with an extension arm installed at the bottom of the main body. A protrusion is located at the end of the extension arm, and a guide ring is placed at the bottom of the support platform. The protrusion is aligned with the guide ring, and the motor is then driven to rotate the extension arm, moving the support platform and thus repositioning the material placed on the support platform within the freeze dryer. However, this technical solution has several shortcomings. First, the material repositioning is a complete displacement of the material on the support platform. Since the freeze-dried material on the support platform is multi-layered, it cannot perform step-by-step displacement of each layer. Second, the extension arm rotates in a circumferential direction, while the support platform moves unidirectionally along the guide ring and slide rail. When the extension arm is aligned with the guide ring at the bottom of the support platform, their directions of movement interfere, meaning the motor cannot drive the support platform to reposition.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] The purpose of this utility model is to provide a durian shell freeze dryer with a support component. The technical problem to be solved is as follows: When the existing freeze dryer moves the internal materials, it is not possible to move each layer of freeze-dried material one by one.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A durian shell freeze dryer with a support assembly includes a main body. A control panel is provided on one side of the top of the main body, and a freeze-drying chamber is provided on the inner side of the top. A chamber door is installed on the outer side of the freeze-drying chamber. Support frames are symmetrically arranged on both sides of the inner wall of the freeze-drying chamber. A freeze-drying box is connected between two support frames at the same horizontal plane. A pushing mechanism is installed on the top side of the freeze-drying chamber away from the chamber door. The pushing mechanism is electrically connected to the control panel. The pushing mechanism includes a shifting component and a positioning component. The shifting component is fixedly connected to the top of the freeze-drying chamber, and the positioning component is installed on one side of the bottom surface of the shifting component. The shifting component is used to push out the freeze-drying box, and the positioning component is used to position the freeze-drying box.

[0009] As a further embodiment of this utility model: a groove is provided on the inner side of each of the support frames near the feeding mechanism, the groove and the positioning component are located on the same vertical plane, and the bottom surface of the shifting component is higher than the top surface of the top freeze-drying box.

[0010] As a further embodiment of this utility model: an inner anti-detachment strip is provided on the outer side of the support frame, and an outer anti-detachment strip is fixedly connected to both sides of the freeze-drying box to the inner anti-detachment strip. The side of the freeze-drying box near the pushing mechanism is a concave arc surface, and air holes are evenly arranged on the bottom surface of the freeze-drying box.

[0011] As a further embodiment of this utility model: the displacement assembly includes a top plate fixedly connected to the top of the freeze-drying chamber, a slide rail is installed on both sides of the top plate, a slide table is slidably connected between the two slide rails, a receiving plate is fixedly connected to the inner side of the slide table, guide rods are slidably connected to both sides of the receiving plate, a base is fixedly connected between the guide rods and the top plate, a cylinder is installed between the middle of the receiving plate and the top plate, and the output end of the cylinder is fixedly connected to the middle of the receiving plate.

[0012] As a further embodiment of this utility model: the positioning component includes a side frame fixedly connected to one side of the bottom surface of the slide table, a motor is installed in the middle of the side frame, a main bevel gear is installed at the output end of the motor, a secondary bevel gear is rotatably connected to one side of the bottom of the side frame, the main bevel gear and the secondary bevel gear mesh, a second slide rail is fixedly connected to the bottom end of the side frame, a gear plate is fixedly connected to one side of the secondary bevel gear, a conveyor belt is sleeved between the gear plate and the bottom end of the second slide rail, a slide block is slidably connected to one side of the second slide rail, and a push rod is fixedly connected to one side of the slide block.

[0013] As a further embodiment of this utility model: the side of the slide away from the push rod is fixedly connected to one side of the conveyor belt, and the push rod is round and fits against the inner side of the freeze-drying box.

[0014] The beneficial effects of this utility model are:

[0015] By installing a control panel on one side of the main body and installing a pusher mechanism with a shifting component and a positioning component at the top corner of the inside of the freeze-drying chamber, after the freeze-drying operation is completed, the positioning component is first manipulated to move its push rod to the freeze-drying box of the target layer. Then, the cylinder of the shifting component is controlled to move the positioning component along the exit direction of the freeze-drying box, so as to realize the fixed-point removal of the freeze-drying box of the target layer. This facilitates the spot inspection of the freeze-drying effect of the durian shells in the freeze-drying box.

[0016] Furthermore, the cylinder's telescopic rod is retracted, and the positioning component is controlled again to adjust the height of the push rod, positioning it to another layer of freeze-drying box. By repeating the pushing action of the shifting component and repeating this process, the function of automatically removing each layer of freeze-drying boxes in the freeze-drying chamber can be realized. This adapts to the actual operation process of the staff removing each layer of durian shells step by step, effectively avoiding the problem that it is not easy for the staff to transfer them together when removing them all at once.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] like Figures 1 to 6 As shown, a durian shell freeze dryer with a support assembly includes a main body 1. A control panel 2 is provided on one side of the top of the main body 1, and a freeze-drying chamber 3 is provided on the inner side of the top. A door 4 is installed on the outer side of the freeze-drying chamber 3. Support frames 5 are symmetrically arranged on both sides of the inner wall of the freeze-drying chamber 3. A freeze-drying box 6 is connected between the two support frames 5 on the same horizontal plane. A pushing mechanism is installed on the top side of the freeze-drying chamber 3 away from the door 4. The pushing mechanism is electrically connected to the control panel 2. The pushing mechanism includes a shifting component 7 and a positioning component 8. The shifting component 7 is fixedly connected to the top of the freeze-drying chamber 3, and the positioning component 8 is installed on one side of the bottom surface of the shifting component 7. The shifting component 7 is used to push out the freeze-drying box 6, and the positioning component 8 is used to position the freeze-drying box 6.

[0027] It should be noted that an exhaust vent is provided on one side of the bottom of the main body 1, and the freezing module of the freeze dryer is located at the bottom of the main body 1, including the condenser, vacuum pump, secondary drying heater and other devices, which is an existing structure. The exhaust vent facilitates the freezing module to extract the internal air of the freeze-drying chamber 3. The control panel 2 is used to control the process of freeze-drying. A sealing ring 9 is provided on the inner side of the chamber door 4, and a locking handle 10 is installed between the chamber door 4 and the main body 1. Through the cooperation of the locking handle 10 and the sealing ring 9, the freeze-drying chamber 3 is in a high-sealing state when the chamber door 4 is closed, which facilitates the improvement of the vacuum degree of the freeze-drying chamber 3 during vacuum treatment and improves the freeze-drying effect.

[0028] like Figure 2 and Figure 6 As shown, each support frame 5 near the feeding mechanism has a through groove 11 on its inner side. The through groove 11 and the positioning component 8 are located on the same vertical plane. The bottom surface of the shifting component 7 is higher than the top freeze-drying box 6.

[0029] An inner anti-detachment strip 12 is provided on the outside of the support frame 5. The inner anti-detachment strip 12 is adapted to the two sides of the freeze-drying box 6 and the outer anti-detachment strip 13 is fixedly connected. The side of the freeze-drying box 6 near the pushing mechanism is concave arc surface. Air holes 14 are evenly arranged on the bottom surface of the freeze-drying box 6.

[0030] It should be noted that when the positioning component 8 is controlled by the displacement component 7 to move the freeze-drying box 6, it will move along the direction close to the support frame 5. Therefore, the support frame 5 is provided with a through groove 11 on the vertical plane on the side close to the positioning component 8 so that the positioning component 8 can be moved and avoid movement interference. The support frame 5 is made of steel and has high support strength. When the freeze-drying box 6 is installed between two support frames 5, the outer anti-detachment strips 13 on both sides are connected with the inner anti-detachment strips 12 on the adjacent side, so as to prevent the freeze-drying box 6 from being excessively displaced during vacuum treatment, and facilitate the freeze-drying box 6 to move along the predetermined track when the positioning component 8 moves the freeze-drying box 6, thus improving the convenience of material discharge. The air passage 14 is used for airflow during vacuum treatment of each layer of freeze-drying box 6.

[0031] like Figures 3 to 5 As shown, the shifting assembly 7 includes a top plate 71 fixedly connected to the top of the freeze-drying chamber 3. Slide rails 72 are installed on both sides of the top plate 71. A slide table 73 is slidably connected between the two slide rails 72. A receiving plate 74 is fixedly connected to the inner side of the slide table 73 at the top. Guide rods 75 are slidably connected to both sides of the receiving plate 74. A base 76 is fixedly connected between the guide rods 75 and the top plate 71. A cylinder 77 is installed between the middle of the receiving plate 74 and the top plate 71. The output end of the cylinder 77 is fixedly connected to the middle of the receiving plate 74.

[0032] The positioning assembly 8 includes a side frame 81 fixedly connected to one side of the bottom surface of the slide table 73. A motor 82 is installed in the middle of the side frame 81. A main bevel gear 83 is installed at the output end of the motor 82. A secondary bevel gear 84 is rotatably connected to one side of the bottom of the side frame 81. The main bevel gear 83 and the secondary bevel gear 84 mesh. A slide rail 85 is fixedly connected to the bottom end of the side frame 81. A gear plate 86 is fixedly connected to one side of the secondary bevel gear 84. A conveyor belt 87 is sleeved between the gear plate 86 and the bottom end of the slide rail 85. A slide block 88 is slidably connected to one side of the slide rail 85. A push rod 89 is fixedly connected to one side of the slide block 88.

[0033] The side of the slide block 88 away from the push rod 89 is fixedly connected to one side of the conveyor belt 87. The push rod 89 is round and fits against the inner arc surface of the freeze-drying box 6.

[0034] It should be noted that after the freeze dryer completes the freeze drying operation, the door 4 is opened. Then, the operator uses the control panel 2 to operate the positioning component 8 of the feeding mechanism. Specifically, controlling the motor 82 to rotate causes the main bevel gear 83 at the end of the motor 82 to drive the secondary bevel gear 84 to rotate. This, in turn, causes the gear disc 86 at the end of the secondary bevel gear 84 to rotate, driving the conveyor belt 87 between the gear disc 86 and the slide rail 85 to move vertically. This causes the slide block 88, fixedly connected to one side of the conveyor belt 87, to shift, and the push rod 89 to adjust its position in the vertical plane until it reaches the inner side of the freeze-drying box 6 of the predetermined layer. Then, the operator operates the shifting component 7, i.e., the cylinder 77, to shift... The telescopic rod moves along the direction of the freeze-drying box 6 out of the chamber under the limit of the two guide rods 75. When it moves, it drives the slide table 73 to move. The side frame 81, which is fixedly connected to the bottom of the slide table 73, moves synchronously. After the side frame 81 moves, the push rod 89, which is integrated with it and positioned, moves synchronously to fit against the inner concave surface of the freeze-drying box 6 until it is pushed out of the chamber door 4 by the cylinder 77, completing the automatic removal of the target layer freeze-drying box 6. Then the cylinder 77 retracts and retracts in the opposite direction to reset, and the positioning component 8 moves the push rod 89 again to repeat the above operation, completing the layer-by-layer removal of the freeze-drying boxes 6 inside the freeze-drying chamber 3, realizing the function of gradually removing the freeze-drying boxes 6 inside the freeze-drying chamber 3.

[0035] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
