DETAILED DESCRIPTION

[0034] ​In order to make the purpose, technical scheme and advantages of the embodiments of the present disclosure clearer, the technical scheme of the embodiments of the present disclosure will be described clearly and completely below in combination with the drawings of the embodiments of the present disclosure. In order to keep the following description of the embodiments of the present disclosure clear and brief, the present disclosure omits the detailed description of known functions and known components to avoid unnecessary confusion of the concept of the present invention.

[0035] Please refer to Figure 1 and Figure 2 and Figure 3 and Figure 4 , the device takes the body 1 as the carrying basis, and the low-temperature sterilization bin 2 is arranged inside the body 1. The inner wall of the sterilization bin is made of a heat preservation material such as a polyurethane foaming layer to ensure that the temperature in the bin is stable in the low-temperature sterilization interval, which is usually-10℃~5℃. The core components include a transmission roller group, a storage cylinder 4, an uncapping structure 5, a gas guiding component 6 and a telescopic guide roller 7.

[0036] A plurality of rows of transmission rollers 3 are arranged in the low-temperature sterilization bin 2 in the horizontal direction. Each row of transmission rollers 3 is distributed up and down and has a parallel axis. The transmission rollers 3 are connected with a driving motor through a chain transmission mechanism and can rotate synchronously and in the same direction. The spacing of the transmission rollers 3 is adapted to the size of the storage cylinder 4, which is used to smoothly drive the storage cylinder 4 to rotate in the low-temperature sterilization bin 2, so as to stir the egg white peptide powder in the storage cylinder 4 and make the sterilization more sufficient.

[0037] Please refer to Figure 5 and Figure 6 The storage cylinder 4 is a cylindrical structure and is adapted to the spacing of two adjacent transmission rollers 3. Specifically, the storage cylinder 4 comprises:

[0038] The cylinder shell 41 is made of ferromagnetic material, has an open front end and a smooth inner wall, and is used to protect the breathable inner liner.

[0039] The plug-in end cover 42 is also made of ferromagnetic material and has a ring-shaped boss at the edge, which can be inserted into the port of the cylinder shell 41 to achieve sealing. The inner side surface is connected with the breathable inner liner at the center.

[0040] The breathable inner liner is composed of an end plate 43, a connecting column 44, a filter screen 45 and a threaded cover 46. The end plate 43 is a circular plastic plate with a diameter adapted to the inner wall of the cylinder shell 41. Six to eight groups of connecting columns 44 are arranged in a ring array between the end plate 43 and the end cover 42 to connect them into one body. The filter screen 45 is a 300-500 mesh stainless steel screen wrapped outside the connecting column 44 to form a cavity for containing the egg white peptide powder, so that the egg white peptide powder cannot pass through the filter screen 45, while the sterilization medium can pass through the filter screen 45 to perform sterilization. A threaded hole is formed in the center of the rear side of the end plate 43, and the threaded cover 46 is connected by threads to close the filter screen cavity. When opened, the powder can be loaded, and the loading amount is 50%-60% of the volume of the cavity, leaving a space for stirring.

[0041] The side surface of the end plate 43 is provided with a piston structure, which is tightly attached to the inner wall of the cylindrical shell 41. When the cylindrical shell 41 rotates, it drives the air-permeable inner container to rotate.

[0042] Referring to Figure 8 The cover opening structure 5 is installed below the middle of every two transmission rollers 3, fixed inside the low-temperature sterilization bin 2, used for automatically opening and closing the storage cylinder 4, and its structure includes a circular guide sleeve 51, a threaded rod 52, a circular sliding block 53, a guide port 54, a first suction accessory 55 and a second suction accessory 56.

[0043] The circular guide sleeve 51 is a fixed base, and a rotatable threaded rod 52 is arranged inside; the circular sliding block 53 is sleeved on the threaded rod 52, and the threaded rod 52 can drive the circular sliding block 53 to move axially along the guide sleeve when the threaded rod 52 rotates; the guide port 54 is arranged on the front end surface of the circular guide sleeve 51, the top of the circular sliding block 53 extends to the outside through the guide port 54 through a support, and the first suction accessory 55 is installed at the end of the support; the second suction accessory 56 is installed at the top of the end of the circular guide sleeve 51 through a support, and cooperates with the first suction accessory 55 to realize the separation and closure of the cylindrical shell 41 and the end cover 42.

[0044] The front end of the guide port 54 is designed in an arc shape, when the circular sliding block 53 drives the first suction accessory 55 to move to the front end of the guide port 54, the first suction accessory 55 can be inclined along the arc-shaped guide port, avoiding interference with the placement process of the storage cylinder 4, and facilitating the smooth placement of the storage cylinder 4 on the transmission roller 3.

[0045] When the storage cylinder 4 is completed sterilization and closed, the circular sliding block 53 will drive the first suction accessory 55 to move to the front end along the guide port 54, and the arc-shaped guide port can guide the first suction accessory 55 to tilt downwardly with the block moving, rather than keeping horizontal, so that the first suction accessory 55 is away from the two transmission rollers 3, so as to form enough space between the two transmission rollers 3, avoiding the collision interference between the first suction accessory 55 and the storage cylinder 4 to be placed; at the same time, the first suction accessory 55 in the inclined state will not block the bearing surface of the transmission roller 3, facilitating the manual or automatic feeding mechanism to place the new storage cylinder 4 smoothly on the two transmission rollers 3, ensuring the continuous and smooth subsequent sterilization process, and solving the problem of the horizontal first suction accessory blocking the feeding path.

[0046] The cylindrical shell 41 and the end cover 42 are both ferromagnetic materials, and the first suction accessory 55 and the second suction accessory 56 are electromagnets, which are attracted by the electromagnets to open the cylindrical shell 41 and the end cover 42.

[0047] The air guide component 6 is installed at the front end of the bottom of the cover opening structure 5, used for introducing the sterilization medium into the air-permeable inner container, ensuring that the sterilization medium can accurately contact the powder in the filter screen 45, and realizing efficient sterilization.

[0048] Referring to Figure 7The telescopic guide roller 7 is installed at the rear end of the bottom of the uncovering structure 5 and used for limiting the storage cylinder 4, and the structure thereof comprises a metal plate 71, a support frame 72, a guide roller 73 and an electromagnet; the top end of the metal plate 71 is hinged to the bottom of the uncovering structure 5, and the bottom end is hinged to the support frame 72; the guide roller 73 is installed on the support frame 72 and can rotate freely; and the electromagnet is installed at the bottom of the telescopic guide roller 7 and used for controlling the overturning state of the support frame 72, facilitating the control of the falling of the guide roller 73 and the contact of the guide roller 73 with the storage cylinder 4, and enabling the telescopic guide roller 7 to be hidden behind the air guide component 6, so that the storage cylinder 4 is not hindered when the storage cylinder 4 is stored.

[0049] When the electromagnet is powered off, the support frame 72 sags under the action of gravity, the guide roller 73 is in contact with the top of the storage cylinder 4, the storage cylinder 4 is limited between the two transmission rollers 3, and the movement deviation is avoided; when the electromagnet is powered on, the support frame 72 in the inclined state is adsorbed to keep it horizontal and lift it up, the guide roller 73 is separated from the storage cylinder 4 and hidden behind the air guide component 6, and the storage cylinder 4 is not affected when it is guided in.

[0050] The low-temperature sterilization method for producing bovine collagen peptide has the following operation specific action logic:

[0051] When the storage cylinder 4 is placed on the transmission roller 3; the driving component of the uncovering structure 5 is started, the threaded rod 52 is rotated, the circular slide block 53 is moved backward, the first suction accessory 55 is moved backward and contacted with the end cover 42 of the storage cylinder 4, and the second suction accessory 56 is moved to the position contacted with the cylinder shell 41. Then, the first suction accessory 55 and the second suction accessory 56 are started to adsorb the end cover 42 and the cylinder shell 41 respectively; the threaded rod 52 is reversely rotated to move the circular slide block 53 forward, the first suction accessory 55 pulls the end cover 42 to move forward, the end cover 42 drives the end plate 43 and the filter screen 45 to be guided out of the cylinder shell 41 through the connecting column 44, so that the breathable inner container is completely exposed in the low-temperature sterilization bin 2, and the preparation for the contact of the sterilization medium with the powder is completed.

[0052] After the storage cylinder 4 is uncovered, the electromagnet of the telescopic guide roller 7 is powered off, the support frame 72 sags, and the guide roller 73 is in contact with the top of the storage cylinder 4 for limiting. The transmission mechanism is restarted to drive all the transmission rollers 3 to rotate synchronously, the transmission roller 3 drives the storage cylinder 4 to rotate slowly, and the air guide component 6 is started to introduce the sterilization medium into the exposed breathable inner container. During the rotation of the storage cylinder 4, the bovine collagen peptide powder in the filter screen 45 is constantly stirred due to the action of gravity, the sterilization medium penetrates through the filter screen 45 and fully contacts with the stirred powder, the overall sterilization is realized, and the local incomplete sterilization caused by the accumulation of the powder is avoided.

[0053] After sterilization is completed and the storage cylinder 4 is closed, the electromagnet of the telescopic guide roller 7 is electrified, the support frame 72 is adsorbed to keep it horizontal and lifted, and the guide roller 73 is separated from the storage cylinder 4. The transmission roller 3 stops rotating, the cover opening structure 5 drives the closed storage cylinder 4 to move to the front end of the transmission roller 3, the threaded rod 52 drives the circular slide block 53 to move backward again, the first suction member 55 pushes the end cover 42, the end plate 43 and the filter screen 45 back into the cylinder shell 41; the second suction member 56 stops working and no longer adsorbs the cylinder shell 41; the first suction member 55 continues to push the end cover 42 and the cylinder shell 41 to be inserted and sealed, and then the first suction member 55 continues to work, the first suction member 55 adsorbs the storage cylinder 4 to move forward, the circular slide block 53 is reset to the front end of the guide port 54, and the first suction member 55 is inclined along the arc-shaped guide port to reserve space for the next storage cylinder 4 to load; at the same time, the storage cylinder 4 moves to the front end of the transmission roller 3, which is convenient for taking out the material to enter the next sterilization process.
