Abstract
Description
Technical Field
[0001] This utility model relates to chemical equipment, specifically a natural plant extract filtration device for food preservative processing. Background Technology
[0002] Plant extracts are substances extracted or processed from plants and are widely used in the pharmaceutical, food, and daily chemical industries. Among them, antioxidants found in some plants are widely used in the production of common food preservatives. Plant extraction processes are basically inseparable from crushing and filtration. The purification effect and final quality of the extract are based on this, making it a very basic and important process.
[0003] The existing plant extract filtration equipment has fixed filter materials that require frequent maintenance and replacement, which increases the workload. Once a filter needs to be replaced, the filtration process needs to be paused, indirectly affecting production efficiency.
[0004] To address the aforementioned issues, we propose an improvement: a natural plant extract filtration device for food preservative processing. Utility Model Content

[0020] Example: Figure 1-3 As shown, a natural plant extract filtration device for food preservative processing includes a filter tank 1. A drain valve pipe 3 is fixedly connected to the bottom of the filter tank 1 by bolts. An inlet pipe 5 is fixedly connected to the top of the back of the filter tank 1. The front end of the inlet pipe 5 passes through the filter tank 1 and bends downward. External boxes 6 are fixedly welded to the left and right sides of the filter tank 1. A film roll 9 is rotatably installed inside the two external boxes 6. A geared motor 8 is installed on the back of the external box 6 on the right side of the filter tank 1. A filter frame plate 12 is installed in the middle of the inside of the filter tank 1. A quartz sand layer 14 is installed inside the filter frame plate 12.
[0021] A bracket 2 is fixedly installed on the bottom outer surface of the filter tank 1 by bolts, and a sealing top cover 4 is hinged to the top of the filter tank 1. The drain valve pipe 3 adopts a chemical solenoid valve.
[0022] The front and rear ends of the film roll 9 are rotatably connected to the middle of the front and back sides of the inner wall of the outer casing 6 via bearings. A bracket is fixedly welded to the bottom of the back side of the outer casing 6 on the right side of the filter tank 1. The bottom of the geared motor 8 is fixedly connected to the top surface of the bracket by bolts.
[0023] The shaft of the geared motor 8 is coaxially and fixedly connected to the shaft of the film roll 9. Both sides of the two external boxes 6 are hinged and fitted with sealed box doors 7. The surface of the film roll 9 on the left side of the filter tank 1 is wound with sterile filter membrane. The top of the inner wall of the filter tank 1 has openings on the left and right sides, and limit roller groups 10 are rotatably installed in both openings.
[0024] The limiting roller assembly 10 consists of two limiting rollers of the same size that are in contact with each other. The right end of the sterile filter membrane of the film roll 9 on the left side of the filter tank 1 passes through the limiting roller assembly 10 on both sides of the filter tank 1 and is fixedly connected to the surface of the film roll 9 on the right side of the filter tank 1.
[0025] The bottom front end of the inlet pipe 5 is located above the middle of the sterile filter membrane inside the filter tank 1. An annular bracket 11 is fixedly welded to the middle of the inner wall of the filter tank 1, and the outer bottom edge of the filter frame plate 12 is in contact with the top surface of the annular bracket 11.
[0026] The top and bottom surfaces of the filter frame plate 12 are both fixedly provided with fiber fabric filter screens 13, and the quartz sand layer 14 is located between the two layers of fiber fabric filter screens 13.
[0027] Working Principle: This natural plant extract filtration device for food preservative processing operates as follows: First, the filter frame plate 12, loaded with a quartz sand layer 14, is placed on the annular bracket 11 inside the filter tank 1. Next, the membrane roll 9, containing unused sterile filter membranes, is loaded into the outer box 6 on the left side of the filter tank 1. One end of the sterile filter membrane is pulled out, passes through two sets of limiting rollers 10, and connects to the membrane roll 9 in the outer box 6 on the right side of the filter tank 1. It can be secured with adhesive tape. Then, the sealing top cover 4 and the sealing doors 7 of the two outer boxes 6 are closed. The extract to be filtered is introduced through the inlet pipe 5, and the reduction motor 8 is started and adjusted to a relatively slow speed, which can be adjusted according to the extract condition. At this time, the sterile filter membrane will pass through... As the filter extract is slowly moved, the used filter membrane is continuously collected onto the membrane roll 9 on the right side of the filter tank 1. After the first filtration by the sterile filter membrane, it undergoes a second filtration through the quartz sand layer 14 inside the fiber fabric filter screen 13 to further purify the extract. To maintain and update the filter media, the membrane roll 9 and filter frame plate 12 need to be replaced. Simply pause the equipment, reconnect the end of the membrane roll 9 that is about to be used to the membrane roll 9 with a brand new, unused filter membrane, and the geared motor 8 drives the connection between the old and new filter membranes to be collected onto the empty membrane roll 9 that has been replaced at the other end. The extract can then be reintroduced for filtration without opening the sealed top cover 4, which is only opened when the filter frame plate 12 needs to be replaced.
[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
