Description

Technical Field

[0001] This application relates to the field of freeze-drying technology, and more specifically, to a freeze-drying processing apparatus for shellfish. Background Technology

[0002] Freeze dryers originated from vacuum freeze-drying technology in the 1820s. In the 21st century, vacuum freeze-drying technology has been widely used in fields other than medicine, biological products, food, blood products, and active substances. Freeze-drying is a drying technology that uses the principle of sublimation. It involves rapidly freezing the substance to be dried at low temperatures and then, in a suitable vacuum environment, allowing the frozen water molecules to directly sublimate into water vapor and escape.

[0003] Raw materials for freeze-drying usually still contain a lot of moisture. Direct freeze-drying is slow, energy-intensive, and has poor results. Freeze-dried products often stick together due to the slow freezing speed, which affects subsequent packaging operations. There are almost no existing patented technologies to prevent sticking and clumping during freeze-drying. Therefore, how to avoid clumping of products during freeze-drying is an urgent technical problem to be solved. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a freeze-drying processing apparatus for shellfish, wherein the oscillating unit drives the moving block to move back and forth, and the material in the material box can shake with the rotating shaft to solve the problem of shellfish sticking together during freeze-drying.

[0005] The objective of this application is achieved through the following technical solution: A freeze-drying processing apparatus for shellfish includes an organism, a refrigeration mechanism, a vacuum hood, a vacuum pump, a swing unit, a material rack, and a pressure relief valve.

The blocking assembly includes a connecting rod and a stop rod, wherein the stop rod is provided at both ends of the bracket.

[0009] As a further improvement of this application, multiple rotating shafts and material boxes are arranged sequentially from top to bottom, with each rotating shaft corresponding to a material box, and the number of material boxes is 2-5.

[0010] As a further improvement of this application, the freeze-drying processing apparatus further includes a pressure gauge and a thermometer, wherein the pressure gauge and the thermometer are located above the vacuum chamber.

[0011] As a further improvement of this application, the axial direction of the rotating shaft is perpendicular to the extension direction of the slide rail.

The same reference numerals in the accompanying drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the described embodiments of this application without creative effort are within the scope of protection of this application.

[0018] Compared to the embodiments shown in the accompanying drawings, feasible embodiments within the scope of this application may have fewer components, other components not shown in the drawings, different components, differently arranged components, or components with different connections, etc. Furthermore, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0019] This application discloses a freeze-drying processing apparatus for shellfish, comprising an organism 1, a refrigeration mechanism 2, a vacuum hood 3, a vacuum pump 4, a swing unit, a material rack 5, and a pressure relief valve 6. A slide rail 10 is provided above the organism 1. The swing unit includes a hydraulic cylinder 7, a moving block 8, and a sliding block 9. The hydraulic cylinder 7 is fixed above the organism 1, and its output shaft is fixedly connected to the moving block 8. The sliding block 9 is located below the moving block 8 and slides in cooperation with the slide rail 10. When the hydraulic cylinder 7 operates, it drives the moving block 8 to swing left and right along the slide rail 10. (Refer to the attached diagram.) Figure 1The movable block 8 is equipped with a cover bottom 11, which is detachably connected to the vacuum cover 3. A material rack 5 is fixed above the cover bottom 11. The vacuum cover 3 seals the material rack 5 for vacuuming. The material rack 5 is equipped with a rotating shaft 12 and a material box 13. Supports 14 are provided on both sides of the material box 13. The support 14 is rotatably connected to the rotating shaft 12. When the oil cylinder 7 drives the movable block 8 to swing left and right along the slide rail 10, the material box 13 rotates around the rotating shaft 12. The material in the material box 13 can shake with the rotating shaft 12. The vacuum pump 4 is located inside the machine body 1. The air inlet of the vacuum pump 4 is connected to the top of the cover bottom 11 for vacuuming the vacuum cover 3. The refrigeration mechanism 2 is connected to the vacuum cover 3. The refrigeration mechanism 2 is connected to the vacuum cover 3 through a pipe. A valve is provided on the pipe. A pressure relief valve 6 is located above the vacuum cover 3. The pressure relief valve 6 is used to balance the air pressure inside and outside the vacuum cover 3, making it convenient to remove the vacuum cover 3 to take out and put in materials.

[0020] The material box 13 is a cuboid structure with an opening at the top. One side wall of the material box 13 is detachable. The purpose of the detachable side wall is to facilitate the removal of freeze-dried materials later. By tilting the material box 13, all the freeze-dried materials can be poured out from the detachable part.

[0021] Specifically, the bottom of the material box 13 has irregular protrusions. These irregular protrusions ensure that the materials do not stick together, especially for sheet-type freeze-dried materials, as they prevent the sheet-like materials from freezing together.

[0022] The bracket 14 is fixed to the two side walls of the material box 13. The bracket 14 has a certain thickness along the axial direction of the rotating shaft 12. A blocking component 15 is provided on the inner side of the material rack 5 and below the rotating shaft 12. The blocking component 15 includes a connecting rod 16 and a stop rod 17. The stop rod 17 is located at both ends of the bracket 14 and has a certain length. It is used to cooperate with the bracket 14 to prevent the bracket 14 from shaking, thereby adjusting the shaking angle of the material box 13.

[0023] Specifically, multiple rotating shafts 12 and material boxes 13 are arranged sequentially from top to bottom, with each rotating shaft 12 corresponding to a material box 13, and the number of material boxes 13 is 3.

[0024] The freeze-drying processing device also includes a pressure gauge and a thermometer, which are located above the vacuum chamber 3. The pressure gauge is used to detect the air pressure inside the vacuum chamber 3, and the thermometer is used to detect the temperature inside the vacuum chamber 3, so as to facilitate monitoring of the working environment of the vacuum chamber 3.

[0025] Specifically, the axial direction of the rotating shaft 12 is perpendicular to the extension direction of the slide rail 10.

[0026] The freeze-drying processing device also includes a PLC controller 18 and a power supply. The PLC controller 18 is located on one side of the front of the machine body 1, and the power supply is electrically connected to the PLC controller 18, the oil cylinder 7, and the refrigeration mechanism 2.

[0027] Specifically, the bottom of the cover 11 is provided with an insertion slot 19 on one side, and the bottom of the vacuum cover 3 is provided with a locking block 20. The locking block 20 cooperates with the insertion slot 19 to ensure the fixation of the vacuum cover 3 and ensure the sealing effect.

[0028] In use, shellfish are placed into the material box 13, the vacuum cover 3 is fixed to the bottom cover 11, and the refrigeration mechanism 2 is started for freezing. The vacuum pump 4 is started to evacuate the vacuum cover 3. Then the swing unit is started, and the oil cylinder 7 drives the moving block 8 to swing left and right along the slide rail 10. The material box 13 rotates around the rotating shaft 12, and the material in the material box 13 can shake with the rotating shaft 12. When the bracket 14 collides with the stop rod 17, the vibration of the material is better realized. After the freeze-drying is completed, the valve and the vacuum pump 4 are closed, the pressure relief valve 6 is opened, the vacuum cover 3 is removed, and the material is taken out.

[0029] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art, all of which fall within the protection scope of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
