Description

Technical Field

[0001] This invention relates to the field of liquid seasoning technology, and in particular to a pressure filter device for the production of liquid seasonings. Background Technology

[0002] In the pressing and filtration stage of soy sauce brewing, the main requirements for mature soy mash are that it be fully fermented, have a uniform texture, moderate moisture content, and be free from contamination by other microorganisms. This ensures efficient filtration and high-quality soy sauce production. Pressing and filtration is a key refining step in soy sauce production, occurring after fermentation. At this point, the soy mash, which has undergone long-term fermentation and is a mixture of solid and liquid states, needs to be physically pressed to separate the liquid soy sauce, i.e., raw soy sauce. This process not only affects the oil yield but also directly impacts the clarity and flavor quality of the soy sauce. Therefore, the raw materials entering the pressing and filtration stage must meet specific conditions.

[0003] Patent document CN202411041190.1 discloses a filtration device and method for handmade soy sauce, including a soy sauce filter press, filter plates, filter cloth, rinsing components, a collection box, a tensioning mechanism, and a replacement mechanism. The soy sauce filter press is slidably connected to axially distributed filter plates, and the filter plates are provided with a replacement mechanism. The filter plates are provided with filter cloth through the replacement mechanism. The soy sauce filter press is slidably connected to a rinsing component, and the soy sauce filter press is fixedly connected to a collection box. The filter plates are provided with a tensioning mechanism.

[0004] However, in actual use, the inventors discovered that high protein precipitation clogged the filter layer, resulting in low efficiency of traditional pressure filtration. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by setting up a sieve unit to screen the raw materials, so that large particles are located in the middle part, thus preventing large particles from getting close to the filter cloth during extrusion and causing filter cloth blockage.

[0006] To address the above technical problems, the following technical solution is adopted: A pressure filtration device for producing liquid seasonings includes a vibrating table, a collection tank mounted on the vibrating table, and a filter cylinder installed inside the collection tank. It also includes a feeding mechanism located above the filter cylinder. The feeding mechanism includes an installation component mounted on a driving component and moving up and down under the drive of the driving component, a directional component swinging up and down on the installation component, and a partition component controlling the automatic output of large particle mixtures from the directional component. After the installation component extends into the filter cylinder, the dilute mixture is guided by the directional component to implant small particles into the central part of the filter cylinder, and then large particles are guided into the filter cylinder and wrapped around the small particles.

[0007] Preferably, the mounting assembly includes: a mounting frame; and a limiting frame, the limiting frame being connected to the mounting frame via a connecting rod and having a circular structure, the diameter of the limiting frame being smaller than the diameter of the filter cartridge.

[0008] Furthermore, the separating component includes: a screen unit, which is mounted on the upper end of the limiting frame and is made of a soft material; a lifting unit, which is mounted on the mounting frame and connected to the middle of the screen unit; and a first driving unit, which drives the lifting unit to move up and down intermittently.

[0009] Optionally, the sieve unit has a filter hole a located on the outer side of the partition assembly and a filter hole b located on the inner side of the partition assembly, wherein the filter hole a is larger than the filter hole b.

[0010] Preferably, the partition assembly includes: a door frame unit, the door frame unit including a sliding frame slidably disposed on the mounting bracket, a door frame with an annular structure mounted on the sliding frame, and a compression spring sleeved on the sliding frame for supporting the door frame on the mounting bracket; and a second drive unit, the second drive unit driving the sliding frame to move up and down intermittently.

[0011] Furthermore, a filter cloth mechanism is also fitted inside the filter cartridge. The filter cloth mechanism includes a clamping component and a rotating component that drives the clamping component to rotate circumferentially. Any filter cloth sleeve is clamped and fixed by the clamping component, and after each filtration action, the rotating component drives the filter cloth sleeve to rotate circumferentially, while two adjacent sets of filter cloth sleeves rotate in opposite directions.

[0012] Optionally, the turnover assembly includes an annular track, a rotating ring that rotates circumferentially on the annular track, a toothed ring disposed outside the rotating ring, a drive wheel that drives the toothed ring to rotate, and a servo unit that drives the drive wheel to rotate.

[0013] Preferably, the clamping assembly includes several sets of clamps evenly arranged along the circumferential direction of the rotating ring.

[0014] Furthermore, a stamping mechanism is also provided on the other side of the fabric-making mechanism, and the stamping mechanism includes a jack.

[0015] Optionally, the stamping mechanism and the fabric feeding mechanism are both mounted on the transmission frame and arranged symmetrically, and the third drive unit drives the transmission frame to rotate circumferentially to switch between them.

[0016] The beneficial effects of this invention are: (1) In this invention, by setting a sieve unit, the raw materials are sieved so that large particles are located in the middle part, avoiding large particles from getting close to the filter cloth during the extrusion process, which would cause the filter cloth to be squeezed into the filter cloth and cause the filter cloth to be blocked. At the same time, by setting a filter cloth mechanism, multiple sets of filter cloths are set, and after each press, the two filter cloths are rotated in opposite directions and rubbed to bring the blocked parts into contact, which effectively solves the problem of high protein precipitation blocking the filter layer. Compared with traditional filter press equipment, this invention can achieve more efficient filter press work and improve the efficiency of liquid seasoning production.

[0017] In summary, this equipment has the advantages of simple structure and long service life, and is especially suitable for the field of liquid seasoning technology. Attached Figure Description

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] Example 1 like Figures 1-9 As shown, a pressure filtration device for producing liquid seasonings includes a vibrating table 1, a liquid collection tank 2 installed on the vibrating table 1, and a filter cylinder 3 installed inside the liquid collection tank 2. It also includes a material distribution mechanism 4 located above the filter cylinder 3. The material distribution mechanism 4 includes an installation component 42 installed on a drive component 41 and moving up and down under the drive of the drive component 41, a directional component 43 swinging up and down on the installation component 42, and a partition component 44 controlling the automatic output of large particle mixtures on the directional component 43. After the installation component 42 extends into the filter cartridge 3, the dilute mixture is guided by the distribution component 43 to partially implant the small particles 100 into the center of the filter cartridge 3, and then guides the large particles 200 into the filter cartridge 3 and wraps them around the small particles 100.

[0030] However, existing filter press equipment still faces several challenges when processing liquid condiments. First, liquid condiments often contain high levels of protein, which can easily precipitate and clog the filter bed during filtration, significantly reducing filtration efficiency. Second, traditional filter press equipment has limited capacity to separate materials of different particle sizes, failing to effectively separate and rationally distribute particles of varying sizes, resulting in uneven filter cake formation and affecting filtration performance. Third, existing equipment often lacks an effective guiding mechanism during material distribution, leading to uneven material distribution. Small particles cannot effectively concentrate in the center of the filter cartridge, and large particles cannot be evenly coated on the outer layer, thus reducing filtration efficiency. Furthermore, existing equipment is complex to operate in terms of filter cloth replacement and cleaning, resulting in high maintenance costs and making it difficult to meet the demands of continuous production.

[0031] Furthermore, such as Figure 3 As shown, the installation component 42 includes: Mounting bracket 421; and The limiting frame 422 is connected to the mounting bracket 421 via a connecting rod 423 and has a circular structure. The diameter of the limiting frame 422 is smaller than the diameter of the filter cartridge 3.

[0032] The filter cartridge 3 is divided into two parts by using a limiting frame 422. The middle part is used to place the mixture containing large particles, and the outer circumference part is used to place the mixture containing small particles. The two parts are relatively isolated and do not interfere with each other, thus preventing the large particles of the mixture from flowing to the outside and affecting the overall pressure filtration effect in the later stage.

[0033] Furthermore, such as Figures 3-6 As shown, the directional component 43 includes: The screen unit 431 is mounted on the upper end of the limiting frame 422 and is made of a soft material. Lifting unit 432, which is mounted on mounting bracket 421 and connected to the middle of screen unit 431; and The first driving unit 433 drives the lifting unit 432 to move up and down intermittently.

[0034] It should be noted that the first driving unit 433 drives the screen unit 431 to move up and down through the lifting unit 432. The screen unit 431 is made of soft or elastic material. When it moves in the vertical direction, the screen unit 431 will deform. During the deformation process, although the filter holes a4311 and b4312 will also deform, when they are in the two extreme states of being spread up and down, the filter holes a4311 and b4312 are in the normal aperture state, which is conducive to the downward flow of the mixture and the upward and downward movement.

[0035] Furthermore, such as Figures 4-6 As shown, the sieve unit 431 has a filter hole a4311 located on the outer side of the partition assembly 44 and a filter hole b4312 located on the inner side of the partition assembly 44, wherein the filter hole a4311 is larger than the filter hole b4312.

[0036] In this process, the filter hole a4311 is set to be larger than the filter hole b4312 to achieve the guiding and diversion of the mixture of different particles.

[0037] Furthermore, such as Figure 7 As shown, the partition assembly 44 includes: Door frame unit 441, the door frame unit 441 includes a sliding frame 4411 slidably mounted on the mounting bracket 421, a door frame 4412 with a ring structure mounted on the sliding frame 4411, and a compression spring 4413 sleeved on the sliding frame 4411 and located between the door frame 4412 and the mounting bracket 421; and The second drive unit 442 drives the sliding frame 4411 to move up and down intermittently.

[0038] In this application, when the middle part of the screen unit 431 bulges downward, the storage cylinder above the feeding mechanism 4 feeds the material into the screen unit 431. Under the action of gravity, the mixture moves along the guide of the screen unit 431 to the downward bulging part of the screen unit 431. At the same time, the larger particles fall into the filter cylinder 3. By setting the partition component 44, the outer circumference of the screen unit 431 is blocked to prevent excess material from overflowing to the outside. Because the material has poor flowability, it needs to be given a certain pause time when flowing downward. Conversely, when the middle part of the screen unit 431 bulges upward, the remaining part of the material containing small particles enters the filter cylinder 3 and is wrapped around the outside of the mixture containing large particles.

[0039] Example 2 like Figures 8-9 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows: Furthermore, a filter cloth mechanism 5 is also sleeved inside the filter cartridge 3. The filter cloth mechanism 5 includes a clamping component 51 and a rotating component 52 that drives the clamping component 51 to rotate circumferentially. Any filter cloth sleeve is clamped and fixed by the clamping component 51, and after each filtration action, the turnover component 52 drives the filter cloth sleeve 6 to rotate in a circle, and the two adjacent filter cloth sleeves 6 rotate in opposite directions.

[0040] Furthermore, the turnover assembly 52 includes an annular track 521, a rotating ring 522 that rotates circumferentially on the annular track 521, a toothed ring 523 disposed outside the rotating ring 522, a drive wheel 524 that drives the toothed ring 523 to rotate, and a servo unit that drives the drive wheel 524 to rotate.

[0041] Furthermore, the clamping assembly 51 includes several sets of clamps 511 evenly arranged along the circumferential direction of the rotating ring 522.

[0042] In this embodiment, by setting the filter cloth mechanism 5, a multi-stage filtration effect is achieved. The filter cloth is clamped by the clamping component 51 and rotated in a circular motion. On the one hand, the two adjacent filter cloths will generate friction during the reverse rotation, which avoids the clogging of the filter holes. On the other hand, it avoids the uneven concentration along the circumferential direction caused by the filter cloth being in one place for a long time, thus improving the service life of the filter cloth.

[0043] Example 3 like Figure 1 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows: Furthermore, a stamping mechanism 6 is also provided on the other side of the fabric-making mechanism 4, and the stamping mechanism 6 includes a jack 61.

[0044] Furthermore, the stamping mechanism 6 and the fabric feeding mechanism 4 are both mounted on the transmission frame 7 and arranged symmetrically, and the third drive unit 8 drives the transmission frame 7 to rotate circumferentially to switch between them.

[0045] It should be noted that in this application, the stamping mechanism 6 is used to complete multiple pressure filtration actions on the raw materials, and the third drive unit 8 is used to switch the work stations of the two processes of pressure filtration and material feeding, so as to improve work efficiency and save downtime waiting time. In addition, the raw liquid after pressure filtration is extracted and collected in a timely manner.
