Technical Field

[0001] This utility model relates to the field of enzymatic hydrolysis device technology, and more specifically, to an enzymatic decolorization tank for materials. Background Technology

[0002] Enzymatic decolorization tanks are indispensable equipment in the biotechnology and food industries. They are primarily used to remove color components from materials through the action of specific enzymes, thereby purifying the product or improving its appearance. This process is crucial for enhancing the market appeal of products and meeting stringent quality standards.

[0003] However, some enzymatic decolorization tanks currently on the market have certain technical limitations in practical applications. One common problem is insufficient stirring, which directly leads to uneven mixing between the enzymatic hydrolysate and the material. Due to uneven mixing, some materials may not be able to come into contact with enough enzymatic hydrolysate, resulting in insufficient decolorization. This situation not only affects the quality of the final product but may also lead to resource waste, requiring more raw materials or a longer time to achieve the expected decolorization effect. Utility Model Content

[0004] The purpose of this invention is to provide an enzymatic decolorization tank to solve the technical problem of insufficient mixing of the enzymatic hydrolysate and the material in the current enzymatic decolorization process.

[0005] This utility model provides an enzymatic decolorization tank, comprising: a decolorization tank body with a feed inlet at the top and a discharge outlet at the bottom; a back spray mechanism, including a main suction pipe disposed near the bottom of the decolorization tank, at least two first back spray manifolds and a first suction pump, wherein the main suction pipe is connected to the first back spray manifolds through the first suction pump, and the first back spray manifolds are evenly distributed along the circumference of the inner wall of the decolorization tank; a stirring mechanism, including a drive motor and a stirring paddle disposed inside the decolorization tank; and a heating mechanism, including an outer heating sleeve fitted on the outer wall of the decolorization tank body and an inner heating ring spaced apart on the inner wall of the decolorization tank body, wherein the inner heating ring and the outer heating sleeve are connected through a heat transfer oil pipeline, and the inner heating ring and the inner wall of the decolorization tank body enclose each other to form an annular heat exchange channel.

[0006] According to one embodiment of the present invention, the first back spray manifold is symmetrically arranged vertically along the inner wall of the decolorizing tank, and the spray direction of each back spray pipe in the first back spray manifold is tangentially pointed to the inner wall of the tank.

[0007] According to one embodiment of the present invention, it also includes a first guide plate, one end of which is fixed to the bottom end of the first return spray manifold, and the other end extends to the inlet of the heat exchange channel.

[0008] According to one embodiment of the present invention, the surface of the stirring paddle blades is coated with a polytetrafluoroethylene coating.

[0009] According to one embodiment of the present invention, heat-conducting oil is introduced into the outer heating jacket and the inner heating ring, and a temperature sensor is provided on the outer wall of the outer heating jacket.

[0010] According to one embodiment of the present invention, it further includes a plurality of second back spray manifolds arranged opposite each other along the axial direction of the decolorizing tank body.

The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Example 1

[0027] This utility model provides an enzymatic decolorization tank for materials to increase decolorization efficiency.

[0028] Please see Figure 1The enzymatic decolorization tank provided in this embodiment includes: a decolorization tank body 100, with an inlet 110 at the top and an outlet 120 at the bottom. The decolorization tank body 100 serves as the main container for the entire decolorization process. The inlet 110 at the top is used to add materials and enzymatic hydrolysants, and the outlet 120 at the bottom is used to discharge the treated materials. A return spray mechanism includes a main suction pipe 210 located near the bottom of the decolorization tank, at least two first return spray manifolds 220, and a first suction pump 230. The main suction pipe 210 is connected to the first return spray manifolds 220 via the first suction pump 230. The first return spray manifolds 220 are evenly distributed circumferentially along the inner wall of the decolorization tank, forming... The strong circulating flow promotes thorough mixing of materials and enzymatic hydrolysate; the stirring mechanism includes a drive motor 310 and a stirring paddle 320 located inside the decolorization tank. The drive motor 310 drives the stirring paddle 320 to rotate, helping the materials and enzymatic hydrolysate to mix more evenly; the heating mechanism includes an outer heating sleeve 410 fitted on the outer wall of the decolorization tank body 100 and an inner heating ring 420 spaced apart on the inner wall of the decolorization tank body 100. The inner heating ring 420 and the outer heating sleeve 410 are connected through a heat transfer oil pipeline 430. The inner heating ring 420 and the inner wall of the decolorization tank body 100 together form an annular heat exchange channel 440. In this embodiment, valves are provided at the discharge port and the inlet port.

[0029] In this embodiment, the first return spray manifold 220 is symmetrically arranged vertically along the inner wall of the decolorization tank, and the spray direction of each return spray pipe in the first return spray manifold 220 is tangentially pointed to the inner wall of the tank, which helps to generate vortices and further enhance the mixing effect of the materials.

[0030] In this embodiment, a first guide plate 240 is also included. One end of the guide plate is fixed to the bottom end of the first return spray manifold 220, and the other end extends to the inlet of the heat exchange channel. This guide plate serves to guide the flow of materials, avoid dead corners, and ensure that the materials are treated more evenly throughout the decolorization tank.

[0031] In this embodiment, the surface of the impeller blades of the stirring paddle 320 is coated with polytetrafluoroethylene, which can reduce material adhesion, facilitate cleaning, and improve corrosion resistance.

[0032] In this embodiment, heat-conducting oil is introduced into the outer heating sleeve 410 and the inner heating ring sleeve 420. A temperature sensor is provided on the outer wall of the outer heating sleeve 410 to ensure uniform heat distribution. The temperature sensor on the outer wall of the outer heating sleeve 410 can monitor the temperature in real time to ensure that the enzymatic hydrolysis process is within the optimal temperature range.

[0033] In this embodiment, the inner wall of the decolorizing tank is mirror-polished to reduce the possibility of material residue and facilitate cleaning and maintenance.

[0034] The following is a detailed description of the usage process of the enzymatic decolorization tank of Embodiment 1 of this utility model:

[0035] The material enters the decolorization tank through the top feed inlet 110 and is initially mixed with the enzymatic hydrolysate with the aid of the stirring mechanism. Subsequently, the material is drawn into the main suction pipe 210 by the action of the first suction pump 230 and tangentially sprayed back into the decolorization tank through the first return spray manifold 220, promoting material circulation and enhancing the mixing effect. The heating system ensures a suitable reaction temperature.

[0037] This utility model provides an enzymatic decolorization tank for materials to increase decolorization efficiency.

[0038] Please see Figure 2 The enzymatic decolorizing tank provided in Embodiment 2 of this utility model differs from that in Embodiment 1 only in that, in this embodiment, it further includes multiple second back spray manifolds 510 arranged axially opposite to each other along the main body 100 of the decolorizing tank. The addition of the second back spray manifolds 510 further enhances the circulation flow pattern of the material in the decolorizing tank, which is more conducive to achieving uniform distribution and mixing of the material. The oppositely arranged second back spray manifolds 510 increase the contact of the material. The second back spray manifolds 510 are connected to the main suction pipe 210 through the first suction pump 230.

The end of the second guide plate 520 extends into the heat exchange channel. The design of the second guide plate 520 helps to guide the flow of materials, avoid possible dead zones, and enable the materials to be processed more evenly throughout the decolorizing tank. It also helps to improve the heat exchange efficiency.

[0042] The embodiments of this utility model have at least the following advantages:

[0043] This invention utilizes a back-spray mechanism (main suction pipe, first back-spray manifold, and first suction pump) to create a strong circulating flow of material within the decolorization tank. Especially when the first back-spray manifold is symmetrically arranged vertically along the inner wall of the decolorization tank and the spray direction is tangentially directed towards the inner wall, it promotes more uniform material dispersion, thereby improving the contact efficiency between the enzymatic hydrolysate and the material. The stirring blades are coated with polytetrafluoroethylene, which not only improves corrosion resistance but also reduces the possibility of material adhesion, helping to maintain better stirring effects. The outer heating jacket and inner heating ring are connected by a heat-conducting oil pipeline, forming an annular heat exchange channel, ensuring uniform temperature distribution. Simultaneously, when material enters the annular heat exchange channel, it further ensures temperature control of the material, preventing temperature inconsistencies between materials near the axis and those near the tank body, thus improving enzymatic hydrolysis efficiency. The mirror-polished inner wall of the decolorization tank reduces the possibility of material residue, facilitating cleaning and maintenance.
