[0032] 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.

[0033] Example 1: This utility model provides the following... Figure 1 and Figure 2 The gradient enzymatic hydrolysis membrane separation device shown includes an enzymatic hydrolysis tank 1. A stirring unit 2 is arranged vertically on the top of the enzymatic hydrolysis tank 1. The stirring unit 2 is used for feeding and stirring during the enzymatic hydrolysis process. The enzymatic hydrolysis tank 1 is configured with an inner and outer double-layer sidewall structure. A first connecting pipe 101 is arranged on the top of the enzymatic hydrolysis tank 1, and a second connecting pipe 102 is arranged on the bottom of the enzymatic hydrolysis tank 1. One end of the first connecting pipe 101 and the second connecting pipe 102 both pass through the space between the double-layer sidewalls of the enzymatic hydrolysis tank 1.

[0034] Specifically, the top of the enzymatic hydrolysis tank 1 is provided with multiple feeding pipes 103, one end of each feeding pipe 103 is connected to the inner wall of the enzymatic hydrolysis tank 1.

[0035] It should be noted that by setting the first connecting pipe 101 and the second connecting pipe 102, the gap between the double-layer sidewalls of the enzymatic hydrolysis tank 1 can be filled with a medium to regulate the temperature of the enzymatic hydrolysis tank 1, thereby making the enzymatic hydrolysis process more stable and orderly. At the same time, the raw materials required for enzymatic hydrolysis can be added into the enzymatic hydrolysis tank 1 through the feeding pipe 103.

[0036] In this scheme, the addition of stirring unit 2 allows the raw materials to be fully mixed under stirring, thereby increasing the contact area for enzymatic hydrolysis and improving the efficiency of enzymatic hydrolysis. Furthermore, a filter or pressure filter structure is set at the discharge end of the enzymatic hydrolysis tank 1 to discharge the hydrolysate for subsequent processing more quickly and efficiently.

[0037] Example 2: This utility model provides the following... Figure 3 and Figure 4 The separation tank 3 shown is used in a gradient enzymatic hydrolysis membrane separation device in Embodiment 1. The separation tank 3 is located at the bottom of the enzymatic hydrolysis tank 1. A connecting structure is provided between the top of the separation tank 3 and the top of the enzymatic hydrolysis tank 1. A supporting structure is provided at the bottom of the separation tank 3. The discharge end of the enzymatic hydrolysis tank 1 is located at the bottom and is sleeved by the separation tank 3. A receiving port is provided at the top of the separation tank 3. A discharge pipe 302 is provided at the bottom of the separation tank 3.

[0038] Specifically, the connection structure includes:

[0039] The first connecting ring 104 is fixedly sleeved on the bottom of the enzymatic hydrolysis vessel 1;

[0040] The second connecting ring 301 is fixedly sleeved on the top of the separation tank 3, and the second connecting ring 301 and the first connecting ring 104 are connected by bolts.

[0041] It should be noted that multiple fixing holes are provided at the top of the first connecting ring 104 and the second connecting ring 301. The first connecting ring 104 and the second connecting ring 301 can be connected by using a bolt structure through the fixing holes, so that the enzymatic hydrolysis tank 1 and the separation tank 3 can be assembled and connected. In order to ensure the sealing of the connection between the enzymatic hydrolysis tank 1 and the separation tank 3, a sealing structure can be set at the connection between the two.

[0042] Specifically, the support structure includes a support ring 4, which is fitted around the bottom of the separation tank 3. Multiple support legs 401 are fixedly connected around the bottom end of the support ring 4. The support legs 401 are used to support the separation tank 3 off the ground, thereby facilitating the discharge pipe 302 to discharge materials.

[0043] Example 3: This utility model provides the following... Figure 5 and Figure 6The membrane separation mechanism shown is applied to the separation tank 3 in Example 2. The membrane separation mechanism is set inside the separation tank 3. Multiple sets of membrane separation mechanisms are vertically stacked for multi-stage separation. The membrane separation mechanism is installed inside the separation tank 3 through the material inlet.

[0044] Specifically, the membrane separation mechanism includes:

[0045] Placement ring 5, with multiple sets of top support members arranged around the side wall of placement ring 5, and the outer ring wall of placement ring 5 is set to be attached to the inner wall of receiving port;

[0046] Separation membrane 6 is disposed at the bottom end of placement ring 5.

[0047] It should be noted that the placement ring 5 is used to support the separation membrane 6. Depending on the required fractionation, the separation membranes 6, positioned at different vertical heights, employ different pore sizes. In this setup, the uppermost separation membrane 6 is an ultrafiltration membrane with a molecular weight cutoff typically between 5000 Da and 10000 Da, used to retain larger peptides (large and medium-sized peptides produced in the first and second stages of enzymatic hydrolysis) and residual trace macromolecular impurities (incompletely degraded proteins and polysaccharide complexes) in the enzymatic hydrolysate. Subsequent separation membranes 6 are nanofiltration membranes with a molecular weight cutoff typically between 200 Da and 1000 Da, used to retain slightly larger peptides (dipeptides and tripeptides), while allowing smaller free amino acids and salts to partially permeate or be partially retained (depending on membrane characteristics).

[0048] Furthermore, the top of the placement ring 5 has multiple storage slots, and the outer wall of the placement ring 5, extending through the storage slots, has multiple support holes 501. The top support includes:

[0049] The top support plate 7 is slidably inserted into the storage slot. The shape of the top support plate 7 is adapted to the opening shape of the storage slot, so as to ensure that the top support plate 7 slides against the wall in the storage slot.

[0050] Support block 701, one end of support block 701 is inserted and connected to the bottom of top support plate 7, and the other end of support block 701 is inserted and connected to one of the support holes 501. Support block 701 is in columnar structure.

[0051] A limiting groove is provided on the inner wall of the intersection of the support block 701 and the top support plate 7. A limiting slider 702 is fixedly connected to one end of the support block 701. The limiting slider 702 is slidably inserted into the limiting groove. A top support spring 703 is provided in the limiting groove.

[0052] It should be noted that by using the top support spring 703 to press the limiting slider 702, the limiting slider 702 always drives the support block 701 to move away from the top support plate 7, thereby ensuring that the support block 701 can stably maintain the insertion connection with the support hole 501, and thus support the top support plate 7. The height of the top support plate 7 can be adjusted by adjusting the height of the top exposed at the top of the storage groove, so that the height gap of the multiple sets of placement rings 5 ​​stacked vertically can be adjusted.

[0053] Furthermore, a support groove 303 is provided on the inner wall of the receiving port. One end of the support block 701 passes through the support hole 501 and is inserted into the support groove 303. Through the insertion of the support block 701 and the support groove 303, the placement ring 5 and the separation tank 3 are assembled and connected, providing guidance for the connection between the two.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
