Description

Technical Field

[0001] This utility model relates to the field of extraction and decolorization, and more specifically to a decolorization device for extracting high-polymerization-degree polylysine. Background Technology

[0002] ε-Polylysine is a polypeptide with antibacterial properties and high safety. It can be digested and broken down into lysine in the human body, making it a nutritional antibacterial agent. It not only inhibits Gram-positive bacteria but also effectively inhibits Gram-negative bacteria, such as *Enterobacter aerogenes* and *Escherichia coli*, thus offering significant advantages in food preservation and spoilage. In Japan and the United States, ε-Polylysine is widely used in food preservation and is recognized as a GRAS product, allowing its unlimited addition to food. In China, ε-Polylysine has also found widespread application, particularly in the fields of food additives and pet food.

[0003] Currently, the general steps for preparing and extracting polylysine are as follows: taking the polylysine fermentation broth, analyzing, decolorizing, washing salts, separating and purifying to obtain high-polymerization polylysine, and then concentrating and drying it. In actual production, activated carbon decolorization devices are generally used. However, the activated carbon in existing decolorization devices reaches saturation during use, so decolorization needs to be stopped frequently to replace the activated carbon, resulting in low decolorization efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a decolorization device for extracting high-polymerization-degree polylysine, which can continuously perform decolorization.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows:

A connecting tube extends from the middle of each C-shaped tube away from the main frame. A connecting ring is provided at the end of each C-shaped tube. A decolorization box is detachably and sealed between the two opposite connecting rings. The decolorization box is used to hold activated carbon. Valves are provided at both ends of the C-shaped tubes.

[0007] The decolorization box includes a cylindrical tube with tapered tubes fixed symmetrically at both ends, and a mesh plate is provided inside the cylindrical tube.

[0008] Each conical tube is fixed with a bellows at the end away from the cylindrical tube, and each bellows is fixed with a retaining ring at the end away from the conical tube. The retaining ring is connected to the connecting ring to form a connection between the decolorizing box and the C-shaped tube.

[0009] The outer end face of the retaining ring is provided with a ring ridge, and the end face of the connecting ring is provided with a ring groove. The ring ridge and the ring groove are connected in a fitting manner.

[0010] A sealing ring is provided between the annular ridge and the annular groove.

[0011] The side of the tube is rotatably connected to a bidirectional screw, and the two ends of the bidirectional screw are respectively threaded to two corresponding retaining rings.

[0014] The insert has limiting edges at both the top and bottom ends. When the insert is inserted into the slot, the slot is located between the two limiting edges.

[0015] The insert block is positioned opposite to the bidirectional screw.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1-7 The following is a detailed description of the decolorization device for the extraction of high-polymerization-degree polylysine:

[0030] A decolorization device for extracting high-polymerization-degree polylysine includes C-shaped tubes 2 symmetrically welded and fixed at both ends of a main frame 1. The ports of the two C-shaped tubes 2 are arranged opposite each other. A connecting tube 3 is welded and fixed to the middle of each C-shaped tube 2 extending away from the main frame 1. A connecting ring 4 is provided at the port of each C-shaped tube 2. A decolorization box is detachably and sealed between the two opposite connecting rings 4. The decolorization box is used to hold activated carbon. Valves are provided at both ends of the C-shaped tubes 2.

[0031] When performing decolorization, the polylysine solution is introduced through the upper connecting tube 3, and then introduced into the decolorization box through the upper C-shaped tube 2. After being decolorized by activated carbon in the decolorization box, it flows into the lower C-shaped tube 2, and finally flows out through another connecting tube 3 to complete the decolorization.

[0032] Because valves are installed on the C-shaped tubes 2, both valves on the same side of the two C-shaped tubes 2 can be closed during use, allowing the elution liquid to pass only through the decolorization tank on the connected side for decolorization. After the activated carbon in this decolorization tank reaches saturation, the valves on the two C-shaped tubes 2 on this side are closed, allowing the elution liquid to flow through the other decolorization tank for decolorization. At this point, the decolorization tank that has reached saturation can be disassembled, the activated carbon replaced, and then reinstalled. When the activated carbon in the other decolorization tank reaches saturation, the above operation is repeated to replace the activated carbon in the decolorization tank. This forms an alternating use of the two decolorization tanks for decolorization, and the activated carbon in the two decolorization tanks is replaced alternately to ensure that the device can continuously perform decolorization.

[0033] Further:

[0034] The decolorization box includes a cylindrical tube 7 with tapered tubes 8 symmetrically welded and fixed at both ends. A mesh plate 9 is provided inside the cylindrical tube 7, thereby forming a holding space for placing activated carbon on the mesh plate 9.

[0035] Each conical tube 8 has one end of a corrugated tube 11 fixed to the end of the conical tube 8 by a clamp. Each corrugated tube 11 has a retaining ring 12 fixed to the end of the conical tube 8. The two can be connected by clamps or by adhesive. The retaining ring 12 is connected to the connecting ring 4 to form a connection between the decolorizing box and the C-shaped tube 2.

[0036] The outer end face of the retaining ring 12 is provided with an annular ridge, and the end face of the connecting ring 4 is provided with an annular groove 5. The annular ridge and the annular groove 5 are connected to each other, so that the retaining ring 12 and the connecting ring 4 can remain coaxial when connected. A sealing ring is provided between the annular ridge and the annular groove 5. When the retaining ring 12 is pressed tightly against the connecting ring 4 for connection, the annular ridge and the annular groove 5 cooperate and press the sealing ring to achieve the purpose of sealing.

[0037] The side of the tube 7 is rotatably provided with a bidirectional screw 13, and the sides of the two retaining rings 12 are provided with support plates. The support plates are provided with through threaded holes, and the two ends of the bidirectional screw 13 are respectively threaded to the through threaded holes on the two corresponding support plates.

[0038] Therefore, when installing or disassembling the decolorizing box, by rotating the bidirectional screw 13, the two support arms can be driven by the thread to move the two retaining rings 12 closer or further away at the same time, so that the two retaining rings 12 are pressed against or away from the two connecting rings 4, thus achieving the purpose of installation or disassembly. Moreover, during installation, the two retaining rings 12 can be driven away by the bidirectional screw 13 to press against the two connecting rings 4 respectively, thereby ensuring that the ring edge and the ring groove 5 are matched and the sealing ring is pressed to achieve the purpose of sealing.

[0039] Further:

[0040] The bidirectional screw 13 has a rubber sleeve in the middle, which facilitates the rotation of the bidirectional screw 13 by rotating the rubber sleeve.

[0041] Further:

[0042] The side of the tube 7 is provided with a plug 10, and the main frame 1 is provided with symmetrical slot seats 6 on the left and right sides of the middle part. The plug 10 can be inserted into the slot seat 6.

[0043] The upper and lower ends of the insertion block 10 are provided with limiting edges. When the insertion block 10 is inserted into the slot seat 6, the slot seat 6 is located between the two limiting edges.

[0044] When installing the decolorizing box, the insert block 10 can be inserted into the slot seat 6 to limit the tube 7, so that the tube 7 is in a coaxial position with the two connecting rings 4. At the same time, the two limiting edges limit the slot seat 6, so that the tube 7 is in the middle position with the two connecting rings 4. Then, by rotating the bidirectional screw 13, the two retaining rings 12 are pressed against the ring groove 5 through the ring edge, so as to complete the quick installation and improve the installation efficiency.

[0045] Further:

[0046] The insert 10 is positioned opposite to the bidirectional screw 13.

[0047] With relative positioning, when the decolorizing box is installed, the bidirectional screw 13 is located on the side away from the main frame 1, which facilitates operation.

[0048] Of course, the above description is not a limitation of this instruction manual, and this utility model is not limited to the examples mentioned above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model are also within the protection scope of this utility model.
