Technical Field

[0001] This utility model relates to the technical field of freeze-drying and sterilization integrated machines, and in particular to a novel freeze-drying and sterilization integrated machine. Background Technology

[0002] The freeze-drying and sterilization integrated machine is an innovative device that deeply integrates freeze-drying technology and low-temperature sterilization technology. It achieves seamless connection of the entire process of "drying-sterilization" through a single device, avoids contact with external microorganisms, eliminates the risk of cross-contamination, and is conducive to the sterilization and drying of materials.

[0003] Traditional freeze-drying and sterilization machines directly place liquid materials into the machine for freeze-drying and sterilization. However, the materials contain impurities and particulate matter, which may clog the pipes and valves of the freeze dryer, affecting the normal operation of the vacuum system. They may also become hiding places for microorganisms, reducing the sterilization effect. Utility Model Content

A filter tube is installed at the material inlet of the freeze-drying and sterilization integrated machine body. A filter assembly is installed inside the filter tube. The filter assembly includes a filter screen, a sintered metal filter element screen, an mounting ring, and a connecting rod.

[0007] The filter screen, sintered metal filter element screen, and mounting ring are connected by two connecting rods. A polytetrafluoroethylene membrane filter is installed inside the mounting ring. Two limiting blocks are installed at one end of the filter tube by screws, and one end of each limiting block is in contact with the two connecting rods.

[0008] In addition, a preferred structure is that the mounting ring has a mounting groove inside, one end of the mounting ring has four threaded holes that communicate with the mounting groove, and a pressure ring is movably disposed inside the mounting groove.

[0009] Furthermore, in a preferred configuration, the edge of the polytetrafluoroethylene membrane filter is located within the mounting groove, and one end of the pressure ring is in close contact with the edge of the polytetrafluoroethylene membrane filter.

[0010] In addition, a preferred structure is that a threaded rod is inserted into the threaded hole, a knob is provided at one end of the threaded rod, and a pressure block is provided at the other end of the threaded rod, which is located in the mounting groove and is in close contact with the pressure ring.

[0011] In addition, a preferred structure is that a chute is provided around the entrance of the freeze-drying and sterilization machine, magnet blocks are provided at both ends of the chute, and notches are provided at the other two ends of the chute.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1-11 A novel freeze-drying and sterilization integrated machine includes a freeze-drying and sterilization integrated machine body 1. A filter pipe 2 is installed at the material inlet of the freeze-drying and sterilization integrated machine body 1. A filter assembly 4 is installed inside the filter pipe 2. The filter assembly 4 includes a filter screen 41, a sintered metal filter element screen 42, an mounting ring 43, and a connecting rod 44.

[0030] The filter screen 41, the sintered metal filter element screen 42, and the mounting ring 43 are connected by two connecting rods 44. A polytetrafluoroethylene membrane filter 431 is installed inside the mounting ring 43. Two limiting blocks 5 are installed at one end of the filter tube 2 by screws, and one end of each limiting block 5 is in contact with the two connecting rods 44.

[0031] Meanwhile, an installation groove 432 is provided inside the installation ring 43, and four threaded holes 433 are provided at one end of the installation ring 43 to communicate with the installation groove 432. A pressure ring 6 is movably provided inside the installation groove 432.

[0032] Furthermore, the edge of the polytetrafluoroethylene membrane filter 431 is located within the mounting groove 432, and one end of the pressure ring 6 is in close contact with the edge of the polytetrafluoroethylene membrane filter 431, thereby pressing and limiting the polytetrafluoroethylene membrane filter 431 downwards.

[0033] At the same time, the threaded rod 7 is inserted into the threaded hole 433. A knob 72 is provided at one end of the threaded rod 7, and a pressure block 71 is provided at the other end of the threaded rod 7, which is located in the mounting groove 432. The pressure block 71 is in close contact with the pressure ring 6, and the pressure block 71 presses down and limits the pressure ring 6, thereby limiting the polytetrafluoroethylene membrane filter 431.

[0034] Furthermore, a groove 11 is provided around the entrance of the freeze-drying and sterilization machine 1. Magnet blocks 3 are provided at both ends of the groove 11. Notches 111 are provided at the other two ends of the groove 11. The notches 111 are adapted to the metal slider 21. The metal slider 21 can enter or leave the groove 11 through the notches 111 to realize the disassembly and assembly of the filter tube 2.

[0035] Meanwhile, slots 22 are provided on both sides of the inner wall of the filter tube 2, and metal sliders 21 are provided at both ends of the bottom of the filter tube 2. The metal sliders 21 slide in the groove 11 and are attracted to the magnet 3 to limit the position of the filter tube 2.

[0036] Furthermore, the connecting rod 44 is inserted into the slot 22, which facilitates the installation of the filter assembly 4 into the filter tube 2.

[0037] It is worth noting that the specific structure and working method of the freeze-drying and sterilization integrated machine body 1 are existing technologies publicly available on the market, and are not technical problems to be solved in this technical solution. Therefore, they will not be described in detail in this utility model.

[0038] In this embodiment, the liquid material is slowly poured into the filter tube 2. The material falls through the filter screen 41, and larger impurities and particles are intercepted. Then, the liquid material passes through the sintered metal filter screen 42, which intercepts some smaller impurities and particles. After falling through the polytetrafluoroethylene membrane filter 431, the liquid material enters the freeze-drying and sterilization machine body 1. Tiny particles and impurities are intercepted. Then, the freeze-drying and sterilization machine body 1 is started. The liquid material is first frozen in the freeze-drying and sterilization machine body 1, then sublimated and dried, and finally deeply sterilized. This completes the freeze-drying and sterilization of the liquid material.

[0039] The filter assembly 4 inside the filter tube 2 needs to be cleaned and replaced regularly. Twist the filter tube 2 forcefully to release the metal slider 21 from the magnet 3. The metal slider 21 will rotate and slide in the groove 11. When the metal slider 21 rotates to the bottom of the notch 111, pull the filter tube 2 upward to remove it. Then use a screwdriver to remove the screw on the limiting block 5 to remove the limiting block 5. Next, remove the filter assembly 4 and clean the filter screen 41 and the sintered metal filter element screen 42 to remove the particles and impurities adsorbed on the filter screen 41 and the sintered metal filter element screen 42. Then turn the knob 72 to drive the threaded rod 7 to rotate. The threaded rod 7 moves upward in the threaded hole 433, thereby driving the pressure block 71 to move upward synchronously. The pressure block 71 then releases the limiting effect on the pressure ring 6. The pressure ring 6 then removes the limit on the PTFE membrane filter 431. The PTFE membrane filter 431 can then be removed and replaced. The edge of the new PTFE membrane filter 431 is placed into the mounting groove 432. Then, the knob 72 is turned to move the threaded rod 7 downward, and the pressure block 71 presses the pressure ring 6. The pressure ring 6 then presses the PTFE membrane filter 431, thus achieving the limit on the PTFE membrane filter 431. Then, the filter assembly 4 is installed into the filter tube 2. The limiting block 5 is installed into the filter tube 2 with screws. Then, the metal slider 21 at the bottom of the filter tube 2 is inserted into the slide groove 11 through the notch 111. Then, the filter tube 2 is rotated 90 degrees, and the metal slider 21 is attracted to the magnet block 3. The filter tube 2 can then be installed onto the main body 1 of the freeze-drying and sterilization machine.

[0040] In this invention, the liquid material enters the main body 1 of the freeze-drying and sterilization machine after passing through the filter tube 2. The filter component 4 filters the impurities and particulate matter in the liquid material, removing the impurities and particulate matter, so that the vacuum system can operate normally and at the same time improve the sterilization effect.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
