Description

Technical Field

[0001] The invention relates to the field of separation technology, and in particular to a filtering device and method for producing food additives. Background Art

[0002] Food additives refer to chemically synthesized or natural substances added to food to improve its quality, color, aroma and taste, as well as for preservation and processing needs. Monosodium glutamate is one of the commonly used food additives. Its chemical composition is sodium glutamate, which is a umami seasoning that is easily soluble in water and has a strong umami taste in its aqueous solution. Soybeans, beets, sugar cane, etc. can be used as raw materials to produce monosodium glutamate. When using sugar cane to produce monosodium glutamate, it is usually necessary to extract the juice from the sugar cane, and then treat the liquid and add microorganisms that can produce a large amount of glutamate for fermentation. In this process, the squeezed sugar cane juice needs to be filtered to ensure the efficiency of subsequent work.

[0026] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0027] like Figure 1-Figure 6 As shown, a filtering device for food additive production includes a filter plate 11 fixedly arranged in a barrel body 10, the filter plate 11 is arranged in an inverted cone shape, a feed pipe 16 is provided on the top of the barrel body 10, a discharge pipe 17 is provided at the bottom of the barrel body 10, a shaft rod 20 is rotatably arranged in the barrel body 10, a scraper 21 and a slag removal assembly are arranged on the shaft rod 20 from top to bottom, the scraper 21 is fixedly connected to the shaft rod 20, the scraper 21 contacts the upper side surface of the filter plate 11, the slag removal assembly includes a shell 30 fixedly connected to the shaft rod 20, the upper side surface of the shell 30 contacts the lower side surface of the filter plate 11, along the rotation direction of the shaft rod 20, the scraper 21 is located in front of the slag removal assembly, and the scraper 21 and the shell 30 extend respectively along the generatrix direction of the inverted cone filter plate 11.

[0028] like Figure 4-Figure 8As shown, the housing 30 has a cavity, the upper end of the housing 30 is provided with a liquid injection hole 31 connected to the cavity, a plate 1 32 and a plate 2 33 are provided in the cavity, the plate 1 32 is provided with a one-way valve 1 321, the plate 2 33 is connected to the housing 30 through an elastic member 1 331, the elastic member 1 331 is specifically a first spring, a tube 1 34 for passing sugarcane juice between the plate 1 32 and the plate 2 33 is installed on the housing 30, the end of the tube 1 34 away from the housing 30 extends vertically downward, the tube 1 34 is provided with a one-way valve 2 341, the end of the plate 2 33 away from the shaft 20 is provided with a rack 1 332, and the end of the housing 30 away from the shaft 20 is provided with a rotation device There is a rotating shaft 35, one end of which is provided with a gear 351 cooperating with a rack 1 332, a plurality of racks 13 are fixedly arranged at intervals along the circumference of the barrel body 10, and the other end of the rotating shaft 35 is provided with a gear 352 cooperating with the rack 13; it can be understood that the function of the one-way valve is to allow the liquid to flow in one direction only and prevent the liquid from flowing in the opposite direction; the one-way valve 321 can only allow the sugarcane juice between the plate 1 32 and the plate 2 33 to flow out through the plate 1 32 and spray to the filter plate 11 through the spray hole 31, and the one-way valve 2 341 can only allow the sugarcane juice located below the filter plate 11 in the barrel body 10 to enter between the plate 1 32 and the plate 2 33 through the tube 1 34.

[0029] Therefore, when the shaft 20 rotates counterclockwise, the housing 30 can rotate counterclockwise with the shaft 20, so that the gear 2 352 on the housing 30 can mesh with the rack 2 13, thereby driving the plate 2 33 to move downward, and the elastic member 1 331 will be compressed. When the plate 2 33 is driven to move downward, negative pressure will be generated between the plate 1 32 and the plate 2 33. At this time, the sugarcane juice cannot enter between the plate 1 32 and the plate 2 33 through the one-way valve 1 321, and the sugarcane juice below the filter plate 11 in the barrel body 10 can pass through the tube 1 34 and the one-way valve 2 34. 1 enters between the first plate 32 and the second plate 33. During the counterclockwise rotation of the shaft 20, when the second gear 352 moves to the gap between two adjacent racks 13, the racks 13 stop constraining the second gear 352. At this time, the elastic member 1 331 is reset and can push the second plate 33 upward, so that the second plate 33 moves upward quickly. At this time, the sugarcane juice between the first plate 32 and the second plate 33 cannot flow out through the one-way valve 2 341, and can only flow out through the one-way valve 1 321 and spray to the filter holes of the filter plate 11 through the spray hole 31.

[0030] like Figure 1-Figure 8As shown, a feed piece 22 is coaxially rotated in the opposite direction in the shaft 20, and the feed piece 22 has a screw blade. The pitch of the screw blade gradually decreases from bottom to top along the axial direction of the shaft 20. A plurality of through holes 201 are opened on the shaft 20 near its top periphery, and a plurality of through holes 202 are provided on the shaft 20 near the upper side of the filter plate 11. A matching plate 23 capable of moving up and down is installed on the top of the shaft 20 through an elastic member 203. The elastic member 203 is specifically a second spring. The lower end surface of the matching plate 23 has a conical surface 231. A hopper 1 is coaxially provided on the top of the barrel body 10 with the shaft 20. 2. The hopper 12 is fixedly connected to the barrel body 10. The bottom of the hopper 12 has a conical surface 121. The hopper 12 is provided with a discharge pipe 122. The top of the shaft 20 is fixedly provided with a plate 3 24 along its radial direction. The lower end of the plate 3 24 is in contact with the conical surface 121. Therefore, when the shaft 20 rotates, the scraper 21 can collect the bagasse on the filter plate 11 into the shaft 20 through the through hole 202. Then, the feeding member 22 can squeeze the bagasse in the process of conveying the bagasse upward into the hopper 12, and make the squeezed sugarcane juice flow back to the filter plate 11 again through the through hole 1 201.

[0031] In this embodiment, the lower end of the shaft rod 20 is fixedly provided with gear three 204 and gear four 205 in sequence from top to bottom, and a motor 14 for driving gear three 204 to rotate is installed at the bottom of the barrel body 10, and a gear five 221 is fixedly provided at the lower end of the feed piece 22, and a gear six 15 meshing with gear four 205 and gear five 221 is rotatably provided at the bottom of the barrel body 10, so that when the motor 14 rotates, the shaft rod 20 and the feed piece 22 can rotate synchronously in opposite directions.

[0032] Specific working principle: Reference Figure 1-Figure 8 , the squeezed sugarcane juice is injected into the barrel 10 from the feed pipe 16, and the motor 14 is controlled to rotate so that the shaft 20 rotates counterclockwise (looking from top to bottom along the axial direction of the shaft 20). The specific rotation direction of the shaft 20 can be referred to Figure 2During this process, the feeding member 22 can rotate clockwise, the plate 23 can move up and down, and suck the sugarcane juice below the filter plate 11 into the cavity and spray it back and forth from the spray hole 31 to the filter plate 11, so that the bagasse in the filter hole of the filter plate 11 is separated from the filter plate 11 upward, and then the scraper 21 can transport the bagasse on the filter plate 11 to the shaft 20 through the through hole 202, and then the feeding member 22 can transport the bagasse upward. The pitch of the blades gradually decreases, and the auger blades can squeeze the bagasse. The matching plate 23 can apply a downward squeezing force to the bagasse under the action of the elastic member 203, so that the sugarcane juice in the bagasse can be squeezed more fully, and then the sugarcane juice flows back to the filter plate 11 through the through hole 1 201 again. The squeezed bagasse will continue to move upward and enter the hopper 12 through the conical surface 231. The plate 3 24 can collect the bagasse in the hopper 12 again and discharge it from the hopper 12 through the discharge pipe 122.

[0033] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
