Description

Technical Field

[0001] The utility model belongs to the technical field of sterilization devices, and particularly relates to a pea protein flash sterilization device. Background Art

[0002] When discharging materials, part of the protein liquid in the traditional flash sterilization device will stick to the wall, and the staff needs to manually clean and maintain it. The process is difficult to operate and time-consuming. Based on this background, our company has designed a protein flash sterilization device for pea protein production with a publication number of CN213793327U. The slider that clamps the scraper is driven up and down by the lead screw, and the protein liquid hanging on the wall in the sterilization chamber is cleaned by the scraper, which greatly improves the cleaning effect and efficiency. However, in actual application, we found that due to the lack of a barrier between the sterilization chamber and the mounting groove, the steam inside the sterilization chamber will directly contact the reciprocating lead screw when the device is running. Under the influence of high-temperature steam for a long time, the lubricating grease on the surface of the lead screw and the slider (lead screw mother seat) will gradually fall off, resulting in an increasing friction of the lead screw drive, a jam in the movement of the slider, and a shortened life of the lead screw; more seriously, these shed lubricating greases will enter the sterilization chamber and pollute the protein liquid. In response to this, we tried to add a sealing strip between the sterilization chamber and the mounting groove to reduce the intrusion of steam, but there was still a gap between the slider and the sealing strip, and this problem could not be completely avoided. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides a pea protein flash sterilization device which adopts a new structure and can isolate the installation groove and the sterilization chamber to solve the above-mentioned problems.

[0024] It should be noted that the directions "front, back, left, right, up, down" mentioned in the text are based on Figure 1 The directions of “front, back, left, right, up, and down” are used as the basis.

[0025] See also Figures 1 to 4 The utility model discloses a pea protein flash sterilization device, comprising a body 1, wherein a sterilization chamber 2 is arranged in the body 1, and mounting grooves 3 are symmetrically provided in the sterilization chamber 2, and screws 4 are arranged in the mounting grooves 3, and a driving mechanism for driving the screws 4 to rotate forward and reverse is arranged on the body 1; each screw 4 is provided with a screw mother seat 5, and a slider groove 6 is provided on the inner side of each mounting groove 3, and a partition 7 is provided between the slider groove 6 and the mounting groove 3, and a slider 8 is provided in the slider groove 6, and a clamping end is provided on the inner side of the two sliders 8, and the two clamping ends jointly clamp an annular scraper 9 and lock it (such as a stainless steel screw lock); a first strong magnet 10 is provided on the inner side of the screw mother seat 5, and a second strong magnet 11 cooperating with the first strong magnet 10 is provided on the slider 8, and the slider 8 can be magnetically connected with the screw mother seat 5 on which the first strong magnet 10 is installed on the other side of the partition 7 through the magnetic force of the second strong magnet 11. The side of the machine body 1 is provided with a material inlet 12 and a steam outlet 13 connected to the sterilization chamber 2. The bottom of the machine body 1 is in a "funnel" shape, and a liquid outlet 14 connected to the sterilization chamber 2 is provided at the center.

[0026] When the driving mechanism drives the two screws 4 to rotate forward or reverse, the screw nut 5 on the screw 4 reciprocates on the screw 4, and drives the slider 8 on the other side of the partition 7 to reciprocate synchronously through the magnetic connection, so that the annular scraper 9 clamped by the two sliders 8 cleans the protein liquid hanging on the wall of the sterilization chamber 2.

[0027] The preferred technical solution in this embodiment is as follows Figure 1 and Figure 2As shown in , the driving mechanism includes a synchronous wheel 15, a synchronous belt 16 and a motor 17. Arc angle steels are welded on the front, back, left and right sides of the body 1. The arc angle steels and the outer side of the body 1 form a wheel cavity 18. A synchronous wheel 15 is arranged in each wheel cavity 18, wherein the left and right synchronous wheels 15 are coaxially connected to one of the lead screws 4, the synchronous belt 16 connects all the synchronous wheels 15, and the motor 17 is arranged on the body 1 and drives and connects one of the lead screws 4.

[0028] The preferred technical solution in this embodiment is as follows Figure 3 As shown in the figure, in order to make the sterilization chamber 2 completely independent, a sleeve 19 cooperating with the synchronous belt 16 is provided in the sterilization chamber 2, so that the transmission structure such as the synchronous belt 16 and its synchronous wheel 15 will not contact with the steam, and at the same time, it also prevents the rubber of the synchronous belt 16 from falling off and polluting the protein liquid in the sterilization chamber 2 after aging.

[0029] The preferred technical solution in this embodiment is based on a newly designed driving mechanism, which improves the motor 17 that is centrally arranged in the prior art to be arranged on one side of the body 1, thereby freeing up the space at the top center of the body 1; on this basis, the top of the body 1 is open and is provided with a hemispherical top cover 20, and the top of the top cover 20 is provided with a steam outlet 13, so that the steam can be better discharged after being collected at the top. Compared with the prior art in which the top of the body 1 is flat and has a built-in transmission mechanism, resulting in the steam outlet 13 being able to be opened only on the side of the body 1, the steam outlet 13 opened in the center of the hemispherical top cover 20 is more in line with the characteristics of steam and is more conducive to the discharge of steam.

[0030] In the preferred technical solution of this embodiment, the partition 7 is a ceramic plate to ensure that the surface of the partition 7 is smooth. After the slider 8 is connected to the screw base 5 through the magnetic attraction of the second strong magnet 11 and the first strong magnet 10, it can smoothly slide up and down following the rotation of the screw 4 and the screw base 5.

[0032] The preferred technical solution in this embodiment is to limit the sliding track of the slider 8 so that it can only slide up and down in the slider groove 6. Figure 4 As shown in , symmetrical limiting grooves are arranged on both sides of the slider groove 6, and limiting blocks cooperating with the limiting grooves are arranged on the slider 8.

[0033] In the preferred technical solution of this embodiment, the machine body 1 is provided with a safety valve interface connected to the sterilization chamber 2 for connecting the safety valve; the machine body 1 is provided with a pressure gauge interface connected to the sterilization chamber 2 for connecting the pressure gauge.

[0036] Under normal circumstances, the annular scraper 9 is at the top of the sterilization chamber 2. When the inner wall of the sterilization chamber 2 needs to be cleaned, the drive mechanism is controlled to drive the screw 4 to operate, so that the annular scraper 9 moves downward to clean the protein hanging on the wall. The screw base 5 moves back and forth on the screw 4 to clean the sterilization chamber 2.
