Description

Technical Field

[0001] This disclosure relates to the field of enzymatic hydrolysis of grain husk raw materials. More specifically, it relates to a biaxial enzymatic hydrolysis tank and enzymatic hydrolysis system for grain husk raw materials. Background Technology

[0002] Grain bran has a wide range of sources. Domestically, wheat bran, a byproduct of wheat milling, amounts to 31 million tons, and rice bran, a byproduct of rice processing, amounts to 15 million tons. To fully utilize these grain bran materials for high-value food applications, pretreatment is necessary. This involves semi-solid enzymatic hydrolysis using xylanase, cellulase, and other enzymes. The dry material concentration during hydrolysis is generally higher than 30%, classifying it as a semi-solid enzymatic hydrolysis system. This high-concentration semi-solid material exhibits poor flowability and high viscosity, placing stringent requirements on the mixing uniformity, material mixing efficiency, and sealing performance of the enzymatic hydrolysis equipment.

[0003] Existing enzymatic hydrolysis equipment is mostly traditional single-shaft stirred tanks or vertical reaction devices. When processing such semi-solid materials, dead zones of stirring are prone to occur, resulting in insufficient contact between enzyme and material, low enzymatic hydrolysis efficiency, and material is prone to adhering to the inner wall of the enzymatic hydrolysis tank, causing waste and cleaning difficulties. The processing capacity and continuity of existing equipment are also difficult to meet the requirements of high-efficiency production, which restricts the industrialization process of high-value utilization of grain husks. Summary of the Invention

[0004] The purpose of this disclosure is to provide a biaxial enzymatic hydrolysis tank and enzymatic hydrolysis system for grain husk raw materials that is easy to clean, mixes materials evenly, and has more automated production, so as to solve at least one of the problems existing in the prior art.

[0005] To achieve the above objectives, the present disclosure adopts the following technical solution:

[0006] This disclosure provides an enzymatic hydrolysis system for grain bran raw materials, comprising:

[0007] support;

[0008] One or two biaxial enzymatic hydrolysis vessels are rotatably connected to a support; and,

[0009] A conveying assembly is located below the biaxial enzymatic hydrolyzer; the conveying assembly is used to receive and transport the material after enzymatic hydrolysis in the biaxial enzymatic hydrolyzer;

[0010] The biaxial enzymatic hydrolysis vessel includes an enzymatic hydrolysis vessel body and a lid that are interlocked and fixed together.

[0011] One side of the cover is dampedly hinged to one side of the enzymatic hydrolysis tank body. After the cover and the enzymatic hydrolysis tank body are fastened together, the other side of the cover is fixed to the other side of the enzymatic hydrolysis tank body by fasteners.

[0012] The enzymatic hydrolysis vessel body and the cover are fastened together to form the cavity of the biaxial enzymatic hydrolysis vessel. The cavity includes two adjacent first chambers and second chambers. Both the first chamber and the second chamber are circular in the radial direction. The adjacent sides of the first chamber and the second chamber overlap to form a structure that is interconnected.

[0013] The cavity includes a stirring assembly, which includes:

[0014] A first stirring assembly is located within the first chamber, and the first stirring assembly is coaxial with the first chamber.

[0015] A second stirring assembly is located within the second chamber, and the second stirring assembly is coaxial with the second chamber.

[0016] The first stirring component and the second stirring component are spaced apart.

[0017] Furthermore, the number of the biaxial enzymatic hydrolysis vessels is two sets, and the two sets of biaxial enzymatic hydrolysis vessels are arranged radially side by side on the support;

[0018] The lids of the two sets of biaxial enzymatic hydrolysis vessels are positioned opposite to the bodies of the enzymatic hydrolysis vessels.

[0019] Furthermore, the inner wall of the cover includes two inner arc surfaces that respectively match the shapes of the first chamber and the second chamber.

[0020] Furthermore, the conveying assembly includes a housing and a spiral conveying component located within the housing, which is coaxially aligned with the biaxial enzymatic hydrolysis tank;

[0021] The top of the housing has an opening, and two opposite edges of the opening are respectively provided with receiving baffles extending upward in an oblique direction. The two receiving baffles are arranged in a funnel shape, and the distance between the openings of the two receiving baffles is not less than the width of the cover in the radial direction.

[0022] Furthermore, the first stirring assembly includes a first stirring shaft and a first stirring blade disposed on the first stirring shaft, with both ends of the first stirring shaft rotatably connected to the first chamber;

[0023] The second stirring assembly includes a second stirring shaft and a second stirring blade disposed on the second stirring shaft, with both ends of the second stirring shaft rotatably connected to the second chamber;

[0024] The first and second stirring blades are staggered in the axial direction.

[0025] Furthermore, the shortest distance between the first stirring blade and the inner surface of the first chamber is 5mm to 20mm;

[0026] The shortest distance between the second stirring blade and the inner surface of the second chamber is 5mm to 20mm.

[0027] Furthermore, the enzymatic hydrolysis tank body includes, from the inside out, a first insulation layer, a first water bath layer, and a first support layer.

[0028] Furthermore, the outer side of the enzymatic hydrolysis tank body includes a first temperature controller, and the first water bath chamber includes a first heater and a first temperature sensor; the control end of the first temperature controller is connected to the first heater, and the acquisition end is connected to the first temperature sensor.

[0029] Furthermore, the cover includes, from the inside out, a second insulation layer, a second water bath layer, and a second support layer.

[0030] Furthermore, the outer side of the cover includes a second temperature controller;

[0031] The second water bath chamber includes a second heater and a second temperature sensor;

[0032] The control terminal of the second temperature controller is connected to the second heater, and the acquisition terminal is connected to the second temperature sensor.

[0033] The beneficial effects of this disclosure are as follows:

[0034] The enzymatic hydrolysis vessel body and lid are hinged, and the biaxial enzymatic hydrolysis vessel can rotate on the support, facilitating the loading and unloading of high-viscosity materials. For example, rotating the biaxial enzymatic hydrolysis vessel to the lid-up position and opening the lid allows for easy material loading; rotating it to the side and then opening the lid upwards allows for smooth unloading. Furthermore, the side-facing design of the biaxial enzymatic hydrolysis vessel makes it easier for users to remove residual material inside, further reducing operational difficulty and cleaning burden. The lid and enzymatic hydrolysis vessel body are secured with fasteners, ensuring the chamber's airtightness and well-suited for loading and unloading semi-solid materials. The damped hinged lid design makes opening and closing the lid more convenient and smooth.

[0035] In this disclosure, for a biaxial enzymatic hydrolyzer, the hydrolyzer body and the cover, which is damped and hinged to the side surface, are fastened together with fasteners to form two parallel cylindrical chambers with overlapping and interconnected sides. These two parallel cylindrical chambers provide ample space for the enzymatic hydrolysis of semi-solid materials, and the interconnected structure formed by the overlapping sides allows the material to flow freely between the two chambers, reduces dead zones in the stirring, and ensures sufficient contact between the material and the enzyme, greatly improving the hydrolysis efficiency.

[0036] In this disclosure, two stirring components are respectively installed in the two chambers. By using a biaxial stirring method, high-concentration, high-viscosity semi-solid materials can be thoroughly stirred. Compared with traditional single-shaft stirring, biaxial stirring can generate stronger shear force and convection effect, further enhancing the mixing uniformity of materials, preventing materials from adhering to the inner wall of the enzymatic hydrolysis tank, reducing material waste, and also reducing cleaning difficulty.

[0048] To more clearly illustrate this disclosure, the following description, in conjunction with embodiments and accompanying drawings, further clarifies the subject matter. Similar components in the drawings are indicated by the same reference numerals. Those skilled in the art should understand that the specific description below is illustrative rather than restrictive and should not be construed as limiting the scope of protection of this disclosure.

[0049] like Figure 1 , Figure 2 as well as Figure 5 The first embodiment of this disclosure provides an enzymatic hydrolysis system for grain husk raw materials;

[0050] Bracket 40;

[0051] One or two biaxial enzymatic hydrolysis vessels 10 are rotatably connected to the support 40; and

[0052] A conveying assembly 50 is positioned below the biaxial enzymatic hydrolysis tank 10; the conveying assembly 50 is used to receive and convey the material after enzymatic hydrolysis by the biaxial enzymatic hydrolysis tank 10.

[0053] The biaxial enzymatic hydrolysis vessel 10 includes an enzymatic hydrolysis vessel body 101 and a lid 102 that are interlocked and fixed together.

[0054] One side of the cover 102 is dampedly hinged to one side of the enzyme hydrolysis tank body 101. After the cover 102 is fastened to the enzyme hydrolysis tank body 101, the other side of the cover 102 is fixed to the other side of the enzyme hydrolysis tank body 101 by fasteners.

[0055] When the enzymatic hydrolysis vessel body 101 and the cover 102 are fastened together, they together form the cavity 105 of the biaxial enzymatic hydrolysis vessel 10. The cavity 105 includes two adjacent first chambers 1051 and second chambers 1052. In the radial direction, both the first chamber 1051 and the second chamber 1052 are circular. The adjacent side portions of the first chamber 1051 and the second chamber 1052 overlap to form a structure that is interconnected.

[0056] The cavity 105 includes a stirring assembly 103, which includes:

[0057] A first stirring assembly 1031 is located in the first chamber 1051, and the first stirring assembly 1031 is coaxial with the first chamber 1051;

[0058] The second stirring assembly 1032 is located in the second chamber 1052 and is coaxial with the second chamber 1052.

[0059] The first stirring component 1031 and the second stirring component 1032 are spaced apart.

[0060] The enzymatic hydrolysis vessel body 101 is hinged to the lid 102, and the biaxial enzymatic hydrolysis vessel 10 can rotate on the support 40, facilitating the loading and unloading of high-viscosity materials. For example, rotating the biaxial enzymatic hydrolysis vessel 10 to the position where the lid 102 faces upwards and then opening the lid 102 allows for easy material loading; rotating it to the side and then opening the lid 102 upwards allows for smooth unloading. Furthermore, due to the lateral orientation of the biaxial enzymatic hydrolysis vessel 10, users can more easily remove residual materials inside the vessel, further reducing operational difficulty and cleaning burden. The lid 102 is fastened to the enzymatic hydrolysis vessel body 101 with fasteners, ensuring the chamber's airtightness and well-suited for loading and unloading semi-solid materials. The damped hinged design of the lid 102 makes opening and closing the lid 102 more convenient and stable.

[0061] In this disclosure, for the biaxial enzymatic hydrolysis vessel 10, the vessel body 101 and the cover 102, which is damped and hinged to the side surface, are fastened together by fasteners to form two parallel cylindrical chambers with overlapping and interconnected sides. These two parallel cylindrical chambers provide ample space for the enzymatic hydrolysis of semi-solid materials, and the interconnected structure formed by the overlapping sides allows the material to flow freely between the two chambers, reduces dead zones in the stirring, and ensures sufficient contact between the material and the enzyme, greatly improving the enzymatic hydrolysis efficiency.

[0062] In this disclosure, two stirring components 103 are respectively installed in the two chambers. By means of biaxial stirring, high-concentration, high-viscosity semi-solid materials can be thoroughly stirred. Compared with traditional single-shaft stirring, biaxial stirring can generate stronger shear force and convection effect, further enhancing the mixing uniformity of materials, preventing materials from adhering to the inner wall of the enzymatic hydrolysis tank body 101, reducing material waste, and also reducing cleaning difficulty.

[0063] In one specific embodiment, the enzymatic hydrolysis vessel body 101 has a side opening, and the cover 102 is dampedly hinged to one side of the opening of the enzymatic hydrolysis vessel body 101. It should be noted that, in this embodiment, the damped hinge means that no relative rotation occurs between the cover 102 and the enzymatic hydrolysis vessel body 101 when no force is applied, and relative rotation only occurs between the cover 102 and the enzymatic hydrolysis vessel body 101 when force is applied; see reference. Figure 1 In this case, for unloading, the cover 102 needs to be flipped up and opened. The damping hinge connection ensures that the cover 102 will not fall after opening to a preset angle, which facilitates unloading.

[0064] In one specific embodiment, the cover 102 is fixed to the other side of the opening of the enzymatic hydrolysis vessel body 101 by a fastener (not shown in the figure); for example, the fastener may be a first protrusion respectively provided on the edge of the opening of the enzymatic hydrolysis vessel body 101 and a second protrusion provided on the edge of the cover 102 for engaging with the first protrusion, and bolts are inserted into the first protrusion and the second protrusion for clamping and fixing. The cover structure is simple and easy to fix.

[0065] In one specific embodiment, a rubber gasket (not shown in the figure) is fixed to the edge of the opening of the enzymatic hydrolysis tank body 101. The cover 102 and the enzymatic hydrolysis tank body 101 are fastened together to clamp the rubber gasket, so that the edge of the cover 102 and the edge of the enzymatic hydrolysis tank body 101 are sealed together. The sealing connection method ensures sufficient sealing inside the enzymatic hydrolysis tank body 101, and avoids moisture loss of the material due to poor sealing during the material stirring and enzymatic hydrolysis process.

[0066] In one possible implementation, there are two sets of biaxial enzymatic hydrolysis vessels 10, which are arranged radially side by side on the support 40; the covers 102 of the two sets of biaxial enzymatic hydrolysis vessels 10 are arranged opposite to the enzymatic hydrolysis vessel bodies 101.

[0067] In one specific embodiment, two biaxial enzymatic hydrolysis vessels 10 are rotatably connected to the support 40, and the enzymatic hydrolysis vessel bodies 101 of the two biaxial enzymatic hydrolysis vessels 10 are fixed back to back. Specifically, the enzymatic hydrolysis vessel bodies 101 of the two biaxial enzymatic hydrolysis vessels 10 are fixedly connected to opposite sides of the cover 102 and are mirror images of each other; both ends of the biaxial enzymatic hydrolysis vessels 10 are fixedly connected to the connecting plates 20 respectively. Figure 7 The mirror-shaped stacked structure ensures that the covers 102 of the two biaxial enzymatic hydrolysis tanks 10 can be opened upwards simultaneously during the unloading process, thus ensuring unloading efficiency.

[0068] In one specific embodiment, a grain husk raw material enzymatic hydrolysis system includes a support 40; two connecting plates 20 disposed opposite to each other on the support 40 and rotatably connected to the support 40; two biaxial enzymatic hydrolysis tanks 10 respectively disposed between the two connecting plates 20; and a conveying assembly 50 disposed below the two horizontal biaxial enzymatic hydrolysis tanks 10 for receiving and conveying the discharge from the two horizontal biaxial enzymatic hydrolysis tanks 10; the enzymatic hydrolysis tank bodies 101 of the two horizontal biaxial enzymatic hydrolysis tanks 10 are fixedly connected on opposite sides of the opening and are mirror images of each other; the two ends of the horizontal biaxial enzymatic hydrolysis tanks 10 are respectively fixedly connected to the connecting plates 20. This invention utilizes a mirror-symmetrical enzymatic hydrolysis tank body 101, and two biaxial enzymatic hydrolysis tanks 10, in conjunction with a support 40 and a connecting plate 20, to achieve rotation of the two biaxial enzymatic hydrolysis tanks 10. This allows for simultaneous unloading of both biaxial enzymatic hydrolysis tanks 10, improving unloading efficiency (specific operations are described in the working principle). It also enables lateral discharge of the biaxial enzymatic hydrolysis tanks 10. Due to their high viscosity, the material adheres to the inner walls of the enzymatic hydrolysis tank body 101 and the cover 102; lateral discharge facilitates the cleaning of this adhered material. The two biaxial enzymatic hydrolysis tanks 10, with their openings fixedly connected to opposite sides and arranged in a mirror image, prevent condensation of water droplets within the chamber formed by the enzymatic hydrolysis tank body 101 and the cover 102, thus reducing the moisture content of the stirred material, while further minimizing the space occupied. The arrangement of two horizontal biaxial enzymatic hydrolysis tanks increases the material storage capacity per batch.

[0069] In a specific example, to improve the stirring volume of the horizontal biaxial enzymatic hydrolysis system, this embodiment sets up two biaxial enzymatic hydrolysis tanks 10. A first motor 104 is connected to the first stirring shaft 10311 and the second stirring shaft 10321 of each biaxial enzymatic hydrolysis tank 10, enabling separate driving of the two shafts. By independently controlling the rotation speed and direction of the two shafts, the rotational speed and direction of the two shafts can be flexibly controlled. For example, different speeds need to be set when stirring high-viscosity materials. When the two stirring shafts rotate in opposite directions at different speeds, the relative speed difference between the blades of the two shafts increases. For example, the high-speed stirring shaft speed is 1.5 to 2 times that of the low-speed stirring shaft, forming a significant speed gradient. This gradient generates strong shear between material layers, which is particularly effective in breaking up agglomerates of high-viscosity materials, accelerating dispersion, saving energy, and improving the stirring effect. A second motor 30 with a reducer is installed on the support 40. The second motor 30 is connected to the connecting plate 20 through the second reducer, and the second motor 30 is used to drive the two biaxial enzymatic hydrolysis tanks 10 to rotate through the connecting plate 20.

[0070] In one possible implementation, the inner wall of the cover 102 includes two inner arc surfaces that respectively match the shapes of the first chamber 1051 and the second chamber 1052. The inner surface of the cover on the top of existing enzymatic hydrolysis mixing equipment is mostly flat. However, the enzymatic hydrolysis process of materials including various enzymes and grain bran raw materials can last up to ten hours. The enzymatic hydrolysis process releases heat, and the internal temperature of the equipment is higher than the external temperature during stirring. If the mixing equipment uses a flat cover for sealing, water droplets will condense on the inner surface of the flat cover; that is, even with the mixing equipment sealed internally, some of the moisture in the material to be hydrolyzed inside the mixing equipment will condense into water droplets. This moisture loss from the material to be hydrolyzed reduces the efficiency of the enzymatic reaction and decreases enzyme activity. Furthermore, general mixing equipment has dead zones, resulting in insufficient material mixing. In addition, due to the high viscosity of the material, it is difficult to remove it from the barrel, leading to low automation and difficult cleaning. In this embodiment, the inner wall of the cover 102 is curved, making it less prone to condensation. Furthermore, it forms a cylindrical chamber with the enzymatic hydrolysis tank body 101. A stirring assembly 103 is coaxially arranged in each of the two chambers. This embodiment employs a dual-shaft stirring assembly 103, resulting in stronger stirring capabilities, and the chambers are cylindrical. On the one hand, in existing enzymatic hydrolysis tanks, the stirring shaft is far from the top cover, preventing the material from touching the top cover during stirring. In contrast, such as... Figure 3 As shown, in this embodiment, the stirring shaft of the stirring assembly 103 is equidistant from the surface of the chamber. During the stirring process, the stirred material can pass through the inner surface of the chamber and absorb moisture that may condense on the chamber surface. In addition, the regular circular cross-section of the chamber surface, which is arranged around the stirring assembly 103, can greatly reduce the dead zones existing in the chamber.

[0071] In one possible implementation, such as Figure 8 As shown, the conveying assembly 50 includes a housing 501 and a spiral conveying component 502 located inside the housing 501 and arranged in the same axial direction as the biaxial enzymatic hydrolysis tank 10.

[0072] The top of the shell 501 has an opening, and two opposite edges of the opening are respectively provided with receiving baffles 503 extending upward in an oblique direction. The two receiving baffles 503 are arranged in a funnel shape, and the distance between the openings of the two receiving baffles 503 is not less than the width of the cover 102 in the radial direction. The setting that the distance between the openings of the receiving baffles 503 is not less than the width of the cover 102 ensures that the receiving baffles 503 can smoothly receive the material after enzymatic hydrolysis in the enzymatic hydrolysis tank, and prevent the material from falling outside the conveying component 50 when the enzyme is unloaded from the biaxial enzymatic hydrolysis tank 10.

[0073] In one specific embodiment, the projected area of ​​the top opening of the screw conveyor and the receiving baffle 503 should be greater than the maximum projected area of ​​the two biaxial enzymatic hydrolysis tanks 10, so that the combination of the top opening and the receiving baffle 503 can smoothly receive the material delivered by the biaxial enzymatic hydrolysis tanks 10. It should be noted that the maximum projected area of ​​the two biaxial enzymatic hydrolysis tanks 10 refers to the area along the top opening of the two biaxial enzymatic hydrolysis tanks 10 when they are rotated to the highest point of the damping hinge between the biaxial enzymatic hydrolysis tank 10 and the cover 102, and the cover 102 is opened 90°. Figure 7 The projected area in the x-direction; the material receiving baffle 503 is designed to ensure that the material can be successfully received and prevent material leakage.

[0074] In one possible implementation, such as Figure 3 The first stirring assembly 1031 includes a first stirring shaft 10311 and a first stirring blade 10312 disposed on the first stirring shaft 10311. The two ends of the first stirring shaft 10311 are rotatably connected to the first chamber 1051.

[0075] The second stirring assembly 1032 includes a second stirring shaft 10321 and a second stirring blade 10322 disposed on the second stirring shaft 10321. Both ends of the second stirring shaft 10321 are rotatably connected to the second chamber 1052. The first stirring blade 10312 and the second stirring blade 10322 are staggered in the axial direction. This staggered distribution creates continuous extrusion between the shafts and provides high shearing efficiency. Furthermore, the staggered blades are subjected to symmetrical forces, offsetting uniaxial off-center load vibration and extending bearing life; this also enables high shearing action at low speeds and reduces motor power consumption.

[0076] In one specific embodiment, the shortest distance between the first stirring blade 10312 and the inner surface of the first chamber 1051 is 5mm to 20mm; the shortest distance between the second stirring blade 10322 and the inner surface of the second chamber 1052 is 5mm to 20mm. This makes the stirring blades and the chamber surfaces sufficiently close in this embodiment. Therefore, the stirring blades effectively scrape off the boundary layer material on the wall surface through strong shearing action during stirring, avoiding the deposition and scaling of high-viscosity materials or solid particles, and eliminating fluid dead zones. Furthermore, a high shear rate can be formed within the narrow gap between the blades and the wall surface, accelerating material dispersion and contact with substrate enzymes in the enzymatic reaction. In addition, this distance can also suppress turbulent separation on the wall surface, reduce stirring energy consumption, and form a dynamic barrier with the sealing structure, preventing particles from migrating into the sealed gap. In scenarios such as cellulose enzymatic hydrolysis and starch gelatinization, this improves reaction efficiency and reduces scaling.

[0077] In one possible implementation, such as Figure 1 and Figure 4 As shown, the minimum distance between the first stirring shaft 10311 and the second stirring shaft 10321 is 40mm to 60mm. Because the material has high viscosity, the distance between the stirring blades cannot be too small. A distance greater than or equal to 40mm can prevent the material from flowing and becoming blocked during stirring. Similarly, high material viscosity leads to poor flowability. Therefore, to avoid dead zones that are not thoroughly stirred, this disclosure uses a distance less than or equal to 60mm, causing the material to form vortices between the stirring blades and improving the mixing uniformity.

[0078] In one possible implementation, the two stirring components 103 within the biaxial hydrolysis tank 10 rotate in opposite directions. When the two shafts rotate in opposite directions, a high-intensity shear zone is formed in the intersecting area of ​​the two stirring components 103, causing the material to be compressed and torn in the middle.

[0079] In one possible implementation, such as Figure 3 The enzymatic hydrolysis vessel body 101 includes, from the inside out, a first insulation layer 108, a first water bath layer 109, and a first support layer 1017. The first water bath layer 109 includes a water bath cavity filled with water. It should be noted that the enzymatic hydrolysis vessel body 101 also includes a first water inlet (not shown in the figure) and a first water outlet (not shown in the figure). The first water inlet is connected to the first water bath layer 109 via the first insulation layer 108; the first water outlet is also connected to the first water bath layer 109 via the first insulation layer 108. The first water inlet and the first water outlet can be sealed with rubber stoppers. The first support layer 1017 and the second support layer 1016 are made of metal to improve heat conduction efficiency.

[0080] In one specific implementation, such as Figure 9A first temperature controller 1010 is provided on the outside of the enzymatic hydrolysis tank body 101, and a first heater 1012 and a first temperature sensor 1011 are provided inside the first water bath chamber. The control terminal of the first temperature controller 1010 is connected to the first heater 1012, and the acquisition terminal is connected to the first temperature sensor 1011. Specifically, in this embodiment, the first water bath chamber is filled with water, and the first temperature controller 1010 can be an ANTHONE 920T electronic temperature controller; the first temperature sensor 1011 uses a PT100 thermocouple, and the first heater 1012 uses a heating rod. Its input interface (the input interface in the above controller includes interface 8, interface 9, and interface 10) is connected to the thermocouple, and its relay output interface (the relay output interface in the above controller includes interface 6 and interface 7) is connected to the heating rod; the user can maintain a constant temperature in the first water bath chamber by setting the desired temperature of the electronic temperature controller.

[0081] In one possible implementation, the cover 102 includes, from the inside out, a second insulation layer 106, a second water bath layer 107, and a second support layer 1016. The second water bath layer 107 includes a water bath cavity filled with water. It should be noted that the enzymatic hydrolysis tank body 101 also includes a second water inlet (not shown in the figure) and a second water outlet (not shown in the figure). The second water inlet is connected to the second water bath layer 107 via the second insulation layer 106; the second water outlet is also connected to the second water bath layer 107 via the second insulation layer 106. The second water inlet and the second water outlet can be sealed with rubber stoppers. The second support layer 1016 is made of metal to improve thermal conductivity.

[0082] Following the above embodiments, as Figure 10 As shown, a second temperature controller 1013 is provided on the outside of the end cap, and a second heater 1015 and a second temperature sensor 1014 are provided inside the second water bath. The control terminal of the second temperature controller 1013 is connected to the second heater 1015, and the acquisition terminal is connected to the second temperature sensor 1014. Similar to the above embodiment, in this embodiment, the second water bath is filled with water, and the second temperature controller 1013 can be an ANTHONE 920T electronic temperature controller; the second temperature sensor 1014 uses a PT100 thermocouple, and the second heater 1015 uses a heating rod. Its input interface (the input interface in the above controller includes interface 8, interface 9, and interface 10) is connected to the thermocouple, and its relay output interface (the relay output interface in the above controller includes interface 6 and interface 7) is connected to the heating rod; the user can maintain a constant temperature in the second water bath by setting the desired temperature of the electronic temperature controller.

[0083] The above controls maintain a constant temperature in the first and second water bath chambers, preventing condensation inside the chambers.

[0084] The working principle of this utility model is as follows:

[0085] At work, such as Figure 5 As shown, rotate the two biaxial enzymatic hydrolysis vessels 10 so that the lid 102 of one of the biaxial enzymatic hydrolysis vessels 10 is facing upwards. Open the lid 102, fill the biaxial enzymatic hydrolysis vessel 10 with material, and after filling, close the lid 102 and tighten it with fasteners. After the lid 102 is tightened, it is as shown. Figure 6 As shown, rotate both biaxial enzymatic hydrolysis vessels 10 clockwise by 180° (before rotation, the hinge between the cover 102 and the vessel body 101 is on the left side of the vessel body 101), so that the cover 102 of the other biaxial enzymatic hydrolysis vessel 10 faces upwards. Open the cover 102, fill the biaxial enzymatic hydrolysis vessel 10 with material, and after filling, close the cover 102 and tighten it with fasteners. Turn on the first motor 104 to drive the stirring shaft for stirring, ensuring thorough stirring and complete enzymatic hydrolysis. After enzymatic hydrolysis is complete, rotate both biaxial enzymatic hydrolysis vessels 10 counterclockwise by 90°, as shown. Figure 7 As shown, the covers 102 of the two biaxial enzymatic hydrolysis tanks 10 face opposite sides. Multiple users simultaneously open the covers 102 of both biaxial enzymatic hydrolysis tanks upwards, allowing the internal material to be poured out and fall into the opening of the screw conveyor via the discharge receiving baffle 503. Multiple users can manually clean the residual material on the body 101 and inner wall of the biaxial enzymatic hydrolysis tanks 10 using a flexible scraper, or they can use a robotic arm with a flexible scraper at its output end (not shown in the figure). The screw conveyor transports the material to the next production line, resulting in a high degree of automation.
