Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a separation and purification device for natto powder processing. Background Technology

[0002] Natto is a traditional fermented food made primarily from soybeans through fermentation with Bacillus subtilis. It is rich in protein, vitamin K2, polyglutamic acid, and nattokinase, a bioactive component with thrombolytic activity, and has gained widespread attention due to its beneficial health benefits. With the rapid development of the health food market, natto powder, as a processed product that is easy to store, transport, and use, is increasingly being used in the production of functional foods, dietary supplements, and health products. During the processing of natto powder, the fermented natto needs to undergo separation and purification to remove undecomposed soybean residue, bacterial residue, and other insoluble impurities, thereby obtaining a high-purity, high-activity extract to provide qualified raw materials for subsequent drying and powdering.

[0003] Currently, in the production of small and medium-sized natto powder, the common separation methods are simple filtration or static sedimentation, which have problems such as low processing efficiency, incomplete separation, and easy clogging of filter media. Although some equipment has introduced centrifugal or membrane filtration technology, which can improve separation accuracy, the structure is complex, the cost is high, and cleaning and maintenance are inconvenient, making it difficult to meet the needs of food-grade continuous production.

[0004] Therefore, it is necessary to design a separation and purification device for natto powder processing to solve the above-mentioned technical problems. Utility Model Content

The stirring rod is vertically arranged, and multiple sets of stirring paddles are evenly arranged along its length.

[0008] To further explain, it also includes a scraper, with the scraper fixedly connected to the lower part of the stirring rod, and the outer edge of the scraper slidingly adhering to the inner wall of the mixing tank.

[0009] To further explain, it also includes a sealing cap and fastening bolts. Both filter tanks have openings at the top, and each opening has a sealing cap. The sealing caps are detachably connected to the filter tanks by fastening bolts.

[0010] To further explain, the filter assembly includes a limiting ring, a filter frame, and a filter bag. The limiting ring is fixedly connected to the upper part of the inner wall of the filter tank. The filter frame is placed inside the filter tank and is limited and supported by the limiting ring.

Figures 1-5As shown, the system includes a mixing tank 1, a support frame 101, a feed inlet 2, a mixing assembly, a first conveying pipe 4, a feed pump 5, a filter tank 6, a filter assembly, a second conveying pipe 7, a discharge pump 8, a collection tank 9, a valve 10, and an observation window 11. The mixing tank 1, filter tank 6, and collection tank 9 are arranged horizontally as basic components. The bottom of the outer wall of the mixing tank 1, each filter tank 6, and the collection tank 9 are all equipped with a support frame 101. The top of the mixing tank 1 has a feed inlet 2 that communicates with the interior. The mixing assembly is installed inside the mixing tank 1, and the first conveying pipe is located on one side of the lower part of the mixing tank 1. 4. A feed pump 5 is provided on the first conveying pipe 4. The first conveying pipe 4 branches to the right and connects to the upper side of two filter tanks 6 arranged in parallel front and rear, and communicates with the interior of each filter tank 6. Each filter tank 6 is equipped with a filter assembly. Both filter tanks 6 have an outlet at the bottom. The outlets converge and connect to the second conveying pipe 7. The second conveying pipe 7 extends to the right to the upper side of the collection tank 9 and communicates with the interior of the collection tank 9. A discharge pump 8 is provided on the second conveying pipe 7. A valve 10 is provided on the bottom side of the collection tank 9. An observation window 11 is provided on the side wall of the collection tank 9 for observing the internal liquid level.

[0022] like Figure 2 , Figure 3 and Figure 5 As shown, the stirring assembly includes a motor 3, a stirring rod 31, a stirring paddle 32, and a scraper 33. The motor 3 is installed at the bottom of the stirring tank 1. The output axis of the motor 3 extends upward through the bottom of the stirring tank 1 and is connected to the stirring rod 31 by welding. The stirring rod 31 is vertically arranged, and multiple sets of stirring paddles 32 are evenly arranged along its length. The scraper 33 is connected to the lower part of the stirring rod 31 by welding. The outer edge of the scraper 33 slides against the inner wall of the stirring tank 1.

[0023] like Figure 2 , Figure 4 and Figure 5 As shown, it also includes a sealing cap 61, a fastening bolt 62, and a filter assembly. Both filter tanks 6 have openings at the top, and each opening is equipped with a sealing cap 61. The sealing cap 61 is detachably connected to the filter tank 6 by the fastening bolt 62. The filter assembly includes a limiting ring 63, a filter frame 64, and a filter bag 65. The limiting ring 63 is welded to the upper part of the inner wall of the filter tank 6.

[0024] Operators can apply the corresponding technical solutions in this device to the separation and purification technology of fermentation liquid in natto powder processing, depending on the specific circumstances.

[0025] When this device is needed to assist in the removal, purification and collection of natto liquid, firstly, the fermented natto liquid is added into the mixing tank 1 through the feed inlet 2. Then, the motor 3 is started to drive the stirring rod 31 and the stirring paddle 32 to rotate, stirring the material in the tank to keep it in a uniform suspension state and prevent the natto residue from settling. At the same time, the scraper 33 rotates with the stirring rod 31 and slides against the inner wall of the mixing tank 1 to remove the sticky substances adhering to the tank wall, thereby improving mixing efficiency and cleanliness.

[0026] After being stirred and homogenized, the material is fed by the feed pump 5 and then bifurcated through the first conveying pipe 4 to the upper part of the two parallel filter tanks 6. The material flows into the filter tank 6 from top to bottom and passes through the filter frame 64 and the filter bag 65 in sequence. Solid impurities such as soybean residue and fungal residue are intercepted by the filter bag 65, and the clear liquid passes through the filter bag 65 into the lower cavity of the filter tank 6.

[0027] The filtered purified liquid flows from the bottom outlets of the two filter tanks 6 to the second conveying pipe 7, and is then conveyed to the collection tank 9 by the discharge pump 8. The liquid level can be monitored in real time through the observation window 11. The purified liquid in the collection tank 9 can be used for subsequent drying and powdering processes. After filtration, the sealing cover 61 is opened, and the filter bag 65 and the trapped residue are taken out for processing, thus completing one work cycle.

[0028] This equipment is specifically designed for the liquid phase separation and purification stage in natto powder processing. Through the synergistic effect of stirring and homogenization, dual-path filtration and automatic discharge, it achieves efficient solid-liquid separation and extraction of active ingredients from natto fermentation liquid. It features a reasonable structure, simple operation, easy cleaning and stable operation.
