The inside of the first enzymatic hydrolysis tank is provided with a grinding and screening net above the main gear and the auxiliary gear. The outside of the rotating rod is provided with a pushing mechanism above the grinding and screening net.

[0004] However, the existing enzymatic hydrolysis tank has the following technical defects: incomplete cleaning, enzyme hydrolysis residues are easily left on the shaft seal of the stirring paddle, the bottom arc transition area and the surface of the coil heating pipe in the tank body, especially for sticky substrates such as starch and protein, manual cleaning needs to disassemble the stirring system, and there are still cleaning blind spots. The traditional system uses fixed spray balls, which can only wash the inner wall of the tank in one direction. If there is residual water on the cleaned inner wall of the tank, microorganisms will easily breed, causing the next batch of enzymatic hydrolysis reaction to be contaminated and the purity of the product to decrease.

[0005] In view of this, in view of the above problems, after in-depth research, the present application is produced.

[0011] The above technical solution precisely sets and controls the enzyme hydrolysis temperature through the touch display screen, avoiding the enzyme activity decline caused by temperature fluctuation.

During cleaning, high-frequency vibrations of 20-40 kHz can be generated, which can produce strong stripping effect on sticky residues such as protein clots and starch paste in areas prone to residue accumulation such as the inner wall of the tank and the root of the stirring blade, improving the residue removal rate, reducing the cleaning blind area compared to simple spray cleaning, solving the residue problem at the shaft seal and the surface of the heating coil of traditional equipment, and avoiding microbial growth and pollution of the next batch of reactions.

[0016] Preferably, the upper ends of the driven gears are rotationally connected to the inside of the drive box, and the driven gears are connected with rotating rods below, and the rotating rods are provided with a plurality of stirring blades at the bottom.

[0017] By adopting the above technical scheme, the stirring blades can not only realize the mixing of materials in the horizontal direction during rotation, but also form axial thrust to promote the up-and-down circulation of materials in the tank, so that the deposition of materials at the bottom can be avoided, the uniform dispersion of high-concentration materials is ensured, and the method is especially suitable for the enzymolysis of starch and protein materials with high viscosity.

[0018] Preferably, the front side of the tank shell is provided with a second servo motor, and a bevel gear set is connected between the output end of the rear side of the second servo motor and the tank shell and the enzymolysis tank body.

[0019] By adopting the above technical scheme, the second servo motor converts the horizontal driving force into vertical driving force through the bevel gear set to drive the rotating of the reciprocating screw rod, so that the automatic lifting of the spraying box is realized, the lifting stroke covers the full height of the enzymolysis tank body, the cleaning can be completed without manual disassembly of the stirring system, the pollutants introduced in the disassembly process are avoided, and the sterile detection pass rate of the tank after cleaning is improved.

[0022] Preferably, the bevel gear set is connected with a reciprocating screw rod at the bottom end, the reciprocating screw rod penetrates into the inside of the sleeve pipe, and a lifting block is threadedly connected to the outer side of the reciprocating screw rod.

[0023] By adopting the above technical scheme, the lifting speed can be slowed down or accelerated according to the degree of residue adhesion in different areas of the tank, the cleaning agent consumption is saved compared with fixed speed spraying, and at the same time, the stubborn residues are ensured to be fully washed, and the residual amount after cleaning is reduced.

[0024] Preferably, three supporting rods are fixedly connected to the outer side of the lifting block, the included angle between the three supporting rods and the center of the lifting block is 120°, and the supporting rods are slidingly connected to the sliding grooves on the outer side of the sleeve pipe.

[0025] The three spraying boxes are arranged in an equilateral triangle shape by the support rods distributed at 120° on the outer side of the lifting block, and the guiding effect of the sleeve sliding groove ensures that the spraying range has no overlap and no omission, and solves the problem of cleaning dead angle at the connection between the tank wall and the bottom of the traditional equipment.

[0027] By the above technical scheme, the high-pressure spray heads on the outer side of the spraying box are controlled by electromagnetic valves, which can realize multi-angle spraying and accurately flush the front and back surfaces of the stirring blade, the surface of the rotating rod and the corners in the tank. The hose connection mode ensures that there is no pipeline winding when the spraying box is lifted, reduces the equipment operation failure rate, and the independent design of the cleaning agent tank facilitates the addition of special enzymatic residue cleaning agent, which improves the flushing efficiency of protein and starch residues.

[0028] Compared with the prior art, the enzymatic tank with a cleaning device has the following advantages:

[0029] 1. Heating waste heat recovery and fan drying cooperation to reduce residual moisture: During the enzymatic process, the fan introduces the waste heat in the enzymatic tank body into the waste heat recovery tank for storage. After cleaning, the waste heat is reversely transported to the tank by the fan, and the airflow circulation in the tank realizes rapid drying. Not only the heating energy is recycled, but also the residual moisture content in the tank can be controlled below 0.5%, avoiding microbial growth and pollution of the next batch of reactions, and solving the problem of residual moisture after cleaning of traditional equipment.

[0030] 2. Reciprocating lifting spraying box realizes full-area dead-angle-free cleaning: The second servo motor drives the bevel gear set and the reciprocating lead screw to drive the spraying box to reciprocate along the sleeve sliding groove, and cooperates with the multi-directional high-pressure spray head to cover the inner wall of the tank, the stirring blade, the rotating rod and the bottom arc area. Compared with the fixed spraying structure, the cleaning coverage is improved, the flushing efficiency of sticky residues such as starch and protein is improved, and the cleaning blind area can be eliminated without manual disassembly.

[0031] 3. Ultrasonic transducer strengthens residue stripping and improves cleaning thoroughness: The ultrasonic transducers arranged in a ring on the outer side of the enzymatic tank body transmit high-frequency vibration to the tank through titanium alloy transmission sheets, and use cavitation effect to strip stubborn residues attached to the tank wall and heating coil surface. In cooperation with the spraying system, the amount of residual residue can be reduced, the amount of chemical cleaning agent can be reduced, hard scraping damage to the inner wall of the tank can be avoided, and the service life of the equipment can be prolonged.

Detailed Implementation

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figures 1-10 The present invention provides a technical solution:

[0045] An enzymatic hydrolysis tank with a self-cleaning device includes a tank shell 1, three shock-absorbing legs 2 at the bottom of the tank shell 1, a drive box 3 at the top of the tank shell 1, a controller 5 at the front of the tank shell 1 with a touch screen display screen at the front of the controller 5, a feed pipe 4 on the top surface of the tank shell 1, and a discharge pipe 27 at the center of the bottom of the tank shell 1. An enzymatic hydrolysis tank body 10 is disposed inside the tank shell 1, and a heating layer 6 is provided between the enzymatic hydrolysis tank body 10 and the tank shell 1. Furthermore, a heating coil 9 is installed inside the heating layer 6, a waste heat recovery box 7 is installed on the rear side of the tank shell 1, and a fan 8 is installed on the top of the tank shell 1. One end of the fan 8 is connected to the inside of the enzymatic hydrolysis tank body 10, and the other end of the fan 8 is connected to the waste heat recovery box 7. A sleeve 19 is fixedly installed inside the middle of the enzymatic hydrolysis tank body 10, and three support rods 23 are slidably connected to the outside of the sleeve 19. A spray box 24 is connected to the end of the support rods 23, and the support rods 23 drive the spray box 24 to form a reciprocating lifting structure.

[0046] The controller 5 is electrically connected to the heating coil 9, which surrounds the outside of the enzymatic hydrolysis vessel body 10. The enzymatic hydrolysis temperature is precisely set and controlled via a touch screen to prevent enzyme activity degradation caused by temperature fluctuations. The design of the heating coil 9 surrounding the outside of the enzymatic hydrolysis vessel body 10 reduces the temperature difference between different areas inside the vessel, ensuring that the enzymatic hydrolysis reaction takes place in a stable environment and effectively improving substrate conversion rate.

[0047] Several ultrasonic transducers 11 are fixedly installed on the outside of the enzymatic hydrolysis tank body 10. The ultrasonic transducers 11 are arranged in a ring on the outside of the enzymatic hydrolysis tank body 10. The contact parts between the ultrasonic transducers 11 and the outside of the enzymatic hydrolysis tank body 10 are made of titanium alloy conductive plates. The ultrasonic transducers 11 arranged in a ring on the outside of the enzymatic hydrolysis tank body 10, together with the titanium alloy conductive plates, enhance the transmission of ultrasonic energy into the tank. During cleaning, high-frequency vibration of 20-40kHz can be generated. This vibration can produce a strong peeling effect on sticky residues such as protein clots and starch paste in areas that are prone to residues, such as the inner wall of the tank and the root of the stirring blade 16. The residue removal rate is improved, and the cleaning blind spots are reduced compared with simple spray cleaning. It solves the problem of residues at the shaft seal and the surface of the heating coil 9 of traditional equipment, and avoids the growth of microorganisms that contaminate the next batch of reaction.

[0048] A first servo motor 12 is fixedly installed on the top of the drive box 3, and an active gear 13 is connected to the output end of the first servo motor 12. Three driven gears 14 are meshed on the outside of the active gear 13. The upper ends of the driven gears 14 are rotatably connected to the inside of the drive box 3, and a rotating rod 15 is connected to the bottom of each driven gear 14. Several stirring blades 16 are provided at the bottom of the rotating rod 15. The stirring range can cover the internal space of the enzymatic hydrolysis tank body 10, avoiding the material accumulation problem of single-axis stirring. The uniformity of material mixing is improved, ensuring that the substrate and enzyme are in full contact, effectively solving the phenomenon of incomplete local enzymatic hydrolysis. When the stirring blades 16 rotate, they can not only achieve horizontal material mixing, but also generate axial thrust to promote the vertical circulation of materials in the tank, which can prevent the sedimentation of materials at the bottom and ensure the uniform dispersion of high-concentration substrates. It is especially suitable for the enzymatic hydrolysis of starch and protein materials with high viscosity.

[0049] A second servo motor 17 is installed on the front side of the outer shell 1 of the tank. The output end of the second servo motor 17 passes through the outer shell 1 and the enzymatic hydrolysis tank body 10 and is connected to a bevel gear set 20. The bevel gear set 20 is rotatably connected to the inside of the protective box 18, and the protective box 18 is fixedly installed on the top surface inside the outer shell 1 of the tank. A sleeve 19 is fixedly installed at the bottom of the protective box 18, and three sliding grooves are opened on the outer side of the sleeve 19. The included angle between the three sliding grooves and the center of the sleeve 19 is 120°. A reciprocating lead screw is connected to the bottom end of the bevel gear set 20. 21, and the reciprocating screw 21 passes through the inside of the sleeve 19, and a lifting block 22 is threadedly connected to the outside of the reciprocating screw 21. Three support rods 23 are fixedly connected to the outside of the lifting block 22, and the included angle between the three support rods 23 and the center of the lifting block 22 is 120°. The support rods 23 are all slidably connected in the sliding groove on the outside of the sleeve 19. The second servo motor 17 converts the horizontal driving force into vertical power through the bevel gear set 20, driving the reciprocating screw 21 to rotate, realizing the automatic lifting of the spray box 24. The lifting stroke covers the enzyme. The entire height of the tank body 10 can be cleaned without manual disassembly of the stirring system, avoiding contaminants that may be introduced during disassembly. The sterility test pass rate of the tank after cleaning is improved. The protective box 18 effectively protects the bevel gear set 20, preventing splashed materials from contaminating the transmission components during enzymatic hydrolysis and extending the service life of the equipment. The 120° evenly distributed sliding grooves on the outer side of the sleeve 19 precisely match the support rod 23 to prevent shaking of the spray box 24 during lifting and lowering, avoiding spray blind spots caused by deviation, and ensuring that the cleaning agent spray coverage of each area of ​​the tank wall is consistent. The lifting speed can be slowed down or accelerated according to the degree of residue adhesion in different areas of the tank, saving cleaning agent compared to fixed speed spraying, while ensuring that stubborn residues are thoroughly rinsed, reducing the residue after cleaning. The 120° distributed support rods 23 on the outer side of the lifting block 22 make the three spray boxes 24 arranged in an equilateral triangle. With the guiding effect of the sliding grooves of the sleeve 19, it ensures that the spray range is non-overlapping and without omissions, solving the problem of cleaning dead corners at the connection between the tank wall and the bottom of traditional equipment.

[0050] Several high-pressure spray heads 25 are connected to the outside of the spray box 24 from multiple directions via solenoid valves. The high-pressure spray heads 25 are connected to the cleaning agent tank 26 via hoses. The cleaning agent tank 26 is fixedly installed on the rear side of the top surface of the tank shell 1. The high-pressure spray heads 25 on the outside of the spray box 24 are controlled by solenoid valves to achieve multi-angle spraying, which can accurately wash the front and back of the stirring blades 16, the surface of the rotating rod 15, and the inner corners of the tank. The hose connection method ensures that there is no pipe entanglement when the spray box 24 is raised and lowered, reducing the failure rate of equipment operation. In addition, the independent design of the cleaning agent tank 26 makes it easy to add special enzymatic residue cleaning agent, which improves the washing efficiency of protein and starch residues.
