Technical Field

[0001] The utility model relates to the technical field of high-protein rice bran processing, in particular to an extracting liquid impurity filtering structure for extracting high-protein rice bran. Background Art

[0002] Rice bran is a cheap, low-utilization but nutritious byproduct of rice processing. The protein in rice bran is a high-quality plant protein with low allergenicity and high biological value. Rice bran protein can be directly used to improve the nutrition and texture of food, and can also be used in the production of bioactive peptides, etc., and has a lot of use value.

[0003] The preparation process of high-protein rice bran requires pretreatment, acid leaching, and extraction processes. The extraction process is to mix the acid leaching liquid with the extractant for defatting, extracting, standing, and separating the high-protein rice bran. This is usually done in an extraction tank, and the separated liquids are discharged from different liquid outlets. In order to reduce the impurities in the extract, it is necessary to filter inside the extraction tank or before the liquid is discharged. If it is filtered inside the tank, it is not easy to clean. A simple way is to filter at the liquid outlet of the extraction tank, but it is easy to block the liquid outlet. Therefore, a simple and convenient filtering structure that is not easy to block the liquid outlet is needed. Utility Model Content

The card block 1 passes through the through hole of the filter screen and is located in the card groove 1 of the first fixed plate.

[0008] Furthermore, the filter screen is a screen plate made of a rigid material, and the edge of the raised portion is concave inwardly toward the second fixed plate to form an annular concave portion.

[0010] Furthermore, the edge of the first fixing plate extends toward and wraps the liquid outlet of the extraction tank, and is threadedly connected to the liquid outlet of the extraction tank.

[0011] Furthermore, the first fixing plate has at least two openings adapted to the liquid outlet of the extraction tank and arranged adjacent to each other; the number of the filter screens corresponds one to one to the number of the openings, and the protrusions of the filter screens are located in the openings.

[0012] Furthermore, the number of the second fixing plates corresponds to the number of the filter screens, and the second fixing plates are clamped and fixed to the first fixing plates.

[0013] Furthermore, a second clamping block is arranged on one side of the first fixing plate facing the liquid outlet of the extraction tank and around the opening, and the liquid outlet of the extraction tank has a second clamping groove adapted to the second clamping block.

[0028] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0029] Example 1

[0030] See also Figure 1-2 This embodiment introduces an extract impurity filtering structure for high-protein rice bran extraction, which is mainly composed of a first fixing plate 1, a second fixing plate 2 and a filter screen 3. The first fixing plate 1 is detachably connected to the liquid outlet of the extraction tank, and an external thread can be set at the end of the liquid outlet of the extraction tank. The edge of the first fixing plate 1 extends toward the liquid outlet of the extraction tank and wraps the liquid outlet of the extraction tank. The extended part is provided with an internal thread and is threadedly connected to the liquid outlet of the extraction tank.

[0031] The second fixing plate 2 is located on the outside of the first fixing plate 1, and the two are clamped and fixed, and the filter screen 3 is limited between the two. Specifically, a plurality of clamping blocks 23 are arranged on the side of the second fixing plate 2 facing the first fixing plate 1, a corresponding clamping groove 1 is opened on the outside of the first fixing plate 1, and through holes corresponding to the number of the clamping blocks 23 are opened on the surface of the filter screen 3. The clamping blocks 23 on the second fixing block pass through the through holes of the filter screen 3 and are located in the clamping groove 1 of the first fixing plate 1, so that the first fixing plate 1 and the second fixing plate 2 are clamped and the filter screen 3 is limited at the same time.

[0032] In order to facilitate the liquid at the liquid outlet of the extraction tank to pass through the first fixed plate 1, the filter screen 3 and the second fixed plate 2 in sequence, the middle parts of the first fixed plate 1 and the second fixed plate 2 are hollowed out to form an opening 11, and the size of the opening 11 is adapted to the size of the liquid outlet of the extraction tank. The filter screen 3 is a mesh plate made of a rigid material, the center of the filter screen 3 protrudes toward the first fixed plate 1 to form a protrusion 31, and the edge of the protrusion 31 is concave toward the second fixed plate 2 to form an annular inner recess 32. The inner recess 32 can store some impurities, and the protrusion 31 and the inner recess 32 have a height difference. When there are impurities in the inner recess 32, the liquid can pass through the filter screen 3 through the protrusion 31 and be discharged from the opening 11 of the second fixed plate 2.

[0033] If the filter 3 needs to be replaced, the second fixing plate 2 can be removed from the first fixing plate 1, and the filter 3 will also be separated from the first fixing plate 1, and the filter 3 can be replaced. Alternatively, the first fixing plate 1 can be rotated to remove the entire filter structure from the liquid outlet of the extraction tank and replace it with a new filter structure.

[0034] In this embodiment, the filter screen 3 can be replaced at any time by means of the clamping connection between the first fixing plate 1 and the second fixing plate 2, which is convenient for replacement and reduces the risk of blockage of the liquid outlet of the extraction tank caused by blockage of the filter screen 3. The raised portion 31 of the filter screen 3 can reduce the probability of the center of the filter screen 3 being covered by impurities, thereby extending the service life of the filter screen 3.

[0035] Example 2

[0036] See also Figure 3-4This embodiment introduces an extract impurity filtering structure for high-protein rice bran extraction, which is basically the same as the extract impurity filtering structure for high-protein rice bran extraction introduced in Example 1. The difference is that the filter screen 3 of this embodiment adopts a mesh plate made of flexible material. Since the flexible material cannot guarantee the continuous state of the protrusion 31. Therefore, the inner wall of the second fixed plate 2 is horizontally connected with a bracket 21, and the number of the brackets 21 is three, which are horizontally fixedly connected to the inner wall of the second fixed plate 2 and are distributed in a triangular shape. The center of the bracket 21 is vertically connected with a support rod 22, and the support rod 22 presses against the center of the filter screen 3 and protrudes toward the first fixed plate 1 to form a protrusion 31. In order to facilitate the press against the protrusion 31, the end of the support rod 22 that contacts the center of the filter screen 3 is an arc surface, and since there is a gap between adjacent brackets 21, the liquid can pass through the filter screen 3 and be discharged through the gap of the bracket 21.

[0037] This embodiment has the same beneficial effects as Embodiment 1.

[0038] Example 3

[0039] See also Figure 5 This embodiment introduces an extract impurity filtering structure for high-protein rice bran extraction, which is basically the same as the extract impurity filtering structure for high-protein rice bran extraction introduced in Example 1. The difference is that the first fixed plate 1 of this embodiment has a certain length, the number of openings 11 is at least two and they are arranged adjacent to each other, and the number of the filter screen 3 and the second fixed plate 2 is consistent with the number of the openings 11. The raised portion 31 of the filter screen 3 is located in the opening 11 and does not exceed the depth of the opening 11. And the first fixed plate 1 is fixed to the liquid outlet of the extraction tank by clamping, that is, the first fixed plate 1 is provided with a clamping block 2 12 on the side facing the liquid outlet of the extraction tank and located around the opening 11, and the liquid outlet of the extraction tank has a clamping groove 2 adapted to the clamping block 2 12.

[0040] When the liquid discharge rate of the filter 3 located at the liquid outlet of the extraction tank is slow, the block 2 12 of the first fixed plate 1 can be detached from the slot 2 of the extraction tank, and another opening 11 with the filter 3 can be aligned and snapped with the liquid outlet of the extraction tank to achieve quick replacement. The filter 3 blocked by impurities can be cleaned and replaced without affecting the drainage of the extraction tank.

[0041] In order to ensure the efficiency of replacing different openings 11, a slider 13 is symmetrically arranged along the length direction of one side of the first fixed plate 1 having the second clamping block 12, and the slider 13 and the second clamping block are staggered, and the height of the slider 13 is higher than the second clamping block 12, and a slide groove is provided at the liquid outlet of the extraction tank, and part of the slider 13 is located in the slide groove. When the second clamping block 12 is separated from the second clamping groove, the slider 13 can also be located in the slide groove, and the other opening 11 can be accurately moved to the liquid outlet of the extraction tank through the guidance of the slider 13 and the slide groove.

[0042] Compared with Embodiment 1, this embodiment can improve the replacement efficiency of the filter screen 3, and the discharge of liquid from the extraction tank is not delayed due to cleaning of the filter screen 3.

[0043] Example 4

[0044] See also Figure 6-7 This embodiment introduces an extract impurity filtering structure for high-protein rice bran extraction, which is basically the same as the extract impurity filtering structure for high-protein rice bran extraction introduced in Example 3. The difference is that the first fixed plate 1 of this embodiment is composed of at least two support plates 14, and the adjacent support plates 14 are connected by hinges. Each support plate 14 has an opening 11, and the filter screen 3 and the second fixed plate 2 correspond to the opening 11 one by one. When one of the support plates 14 is located at the liquid outlet of the extraction tank, the other support plate 14 can be bent without occupying space.

[0045] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
