A fixed column 21 is fixedly connected to the lower side of the heating shell 11, and the fixed column 21 slides inside the liquid storage shell 2. The fixed column 21 is used to squeeze the hydraulic oil in the liquid storage shell 2 outward. A spring is fixedly connected between the liquid storage shell 2 and the fixed column 21 to maintain the initial position of the fixed column 21 and drive the fixed column 21 to reset upward after moving. The left part of the lower side of the heating shell 11 is fixedly connected to a multi-stage telescopic rod 22. The multi-stage telescopic rod 2 The fixed part of the multistage telescopic rod 22 is connected with the liquid storage shell 2 through a connecting pipe, and the hydraulic oil in the liquid storage shell 2 is transported to the fixed part of the multistage telescopic rod 22 through the connecting rod by the fixed column 21, so as to drive the telescopic end of the multistage telescopic rod 22 to move upward, and the telescopic part of the multistage telescopic rod 22 passes through the heating shell 11 and is slidably connected thereto, and the telescopic end of the multistage telescopic rod 22 is fixedly connected to the sealing ring 16, and the telescopic end of the multistage telescopic rod 22 synchronously drives the sealing ring 16 to move, so as to change the volume between the heating shell 11 and the liquid storage tank 12.

[0024] Please refer to Figure 2-Figure 4 Reading this paragraph, a driving motor 3 electrically connected to the control terminal is installed on the lower side of the interior of the bracket 1, a connecting shaft 31 is rotatably connected to the interior of the liquid storage tank 12, the connecting shaft 31 passes through the sealing cover 13 and is rotatably connected thereto, a sealing tube 311 is provided at the lower end of the connecting shaft 31, the sealing tube 311 passes through the discharge pipe 18 and is fixedly connected thereto, the connecting shaft 31 is driven to move synchronously by the liquid storage tank 12 during the movement, a first gear 32 is rotatably connected to the lower side of the interior of the bracket 1, the connecting shaft 31 passes through the first gear 32 and is splined thereto to avoid the first gear 32 from affecting the movement of the connecting shaft 31 and ensure that the connecting shaft 31 can move synchronously with the liquid storage tank 12, the output shaft of the driving motor 3 is fixedly connected to the second gear 33 meshing with the first gear 32, The connecting shaft 31 is driven to rotate by the transmission of the second gear 33 and the first gear 32. The connecting shaft 31 is fixedly connected with two fixed frames 34 symmetrically distributed on the left and right. The lower end of the connecting shaft 31 is provided with two connecting frames 35 symmetrically distributed on the left and right. The connecting frame 35 and the fixed frame 34 are both located inside the liquid storage tank 12. The fixed frame 34 is fixedly connected with first stirring blades 36 distributed equidistantly. The connecting frame 35 is fixedly connected with second stirring blades 361 distributed equidistantly. The first stirring blade 36 and the second stirring blade 361 are both arranged in an inclined shape, and the stirring blades 36 on different fixed frames 34 are symmetrically distributed. The second stirring blades 361 on different connecting frames 35 are symmetrically distributed. The stirring blades 36 are driven by the connecting shaft 31 to rotate synchronously, and the stirring blades 36 guide the original liquid in the liquid storage tank 12.

[0025] When using the device, the staff first opens the sealing cover 13, and then injects the original liquid into the liquid storage tank 12 until the liquid level of the original liquid in the liquid storage tank 12 is flush with the upper side of the fixing frame 34. The staff then stops injecting the original liquid into the liquid storage tank 12, and then reinstalls the sealing cover 13 to the upper side of the liquid storage tank 12.

[0026] In the above process of injecting the original liquid into the liquid storage tank 12, as the volume of the original liquid in the liquid storage tank 12 gradually increases, the overall weight of the liquid storage tank 12 gradually increases synchronously, thereby gradually increasing the overall weight of the heating shell 11 and its internal parts, so that the liquid storage tank 12 drives the heating shell 11 and other parts connected thereto to gradually move downward along the bracket 1, and at the same time, the liquid storage tank 12 drives the connecting shaft 31 to move downward along the first gear 32, and the heating shell 11 drives the multi-stage telescopic rod 22 and other parts connected thereto to move downward synchronously.

[0027] During the downward movement of the heating shell 11, the heating shell 11 drives the fixed column 21 to move downward synchronously along the liquid storage shell 2, so that the spring inside the liquid storage shell 2 is compressed and stored, and the fixed column 21 squeezes the hydraulic oil in the liquid storage shell 2 into the fixed part of the multi-stage telescopic rod 22 through the connecting pipe, so that the telescopic end of the multi-stage telescopic rod 22 moves upward, thereby driving the sealing ring 16 to move upward, so as to change the volume between the heating shell 11, the liquid storage tank 12 and the sealing ring 16, and change the heating area of ​​the liquid storage tank 12.

[0028] Until the injection of the original liquid into the liquid storage shell 2 is stopped, the heating shell 11 and other parts connected thereto move downward to the limit position, and at the same time, the telescopic end of the multi-stage telescopic rod 22 and the sealing ring 16 move upward to the limit position (at this time, the lower side of the sealing ring 16 is located at the upper part of the upper side of the fixing frame 34), and then the control terminal starts the vacuum pump to extract the air in the liquid storage tank 12 through the exhaust pipe 131, so that the interior of the liquid storage tank 12 is in a negative pressure state.

[0029] After the air in the liquid storage tank 12 is extracted, the control terminal starts the hot air pump 14 and the drive motor 3, and the output end of the hot air pump 14 transmits hot air to the heating shell 11 through the first air pipe 15 to heat the liquid storage tank 12, so that the original liquid in the liquid storage tank 12 is heated, and the steam generated by the heated original liquid in the liquid storage tank 12 is sucked by the vacuum pump and flows outward along the exhaust pipe 131, ensuring that the interior of the liquid storage tank 12 is always in a negative pressure state during the use of the device, and the gas after heat exchange is discharged outward along the outlet pipe on the upper side of the sealing ring 16.

[0030] After the control terminal starts the driving motor 3, the output shaft of the driving motor 3 drives the connecting shaft 31 to rotate synchronously through the transmission of the second gear 33 and the first gear 32, and the connecting shaft 31 drives the two fixing frames 34 and the two connecting frames 35 thereon to rotate synchronously, and the two fixing frames 34 and the two connecting frames 35 respectively drive the adjacent stirring blades 36 to rotate synchronously, and the stirring blade 36 on the left side pushes the original liquid in the liquid storage tank 12 close to the connecting shaft 31 in the direction away from the connecting shaft 31, and the stirring blade 36 on the right side pushes the original liquid in the liquid storage tank 12 away from the connecting shaft 31 in the direction close to the connecting shaft 31 (both the left and right sides are Figure 3 For example, the original liquid in the liquid storage tank 12 is heated evenly, and the evaporation rate of the original liquid in the liquid storage tank 12 is increased. The temperature of the hot air is monitored by the temperature detector, and the detection result is transmitted to the control terminal. The control terminal changes the power of the hot air pump 14 according to the value of the temperature detector to realize automatic temperature control.

[0031] In the above-mentioned process of heating and evaporating the original liquid in the liquid storage tank 12, as the water in the original liquid in the liquid storage tank 12 is gradually evaporated, the volume of the original liquid in the liquid storage tank 12 is gradually reduced, that is, the liquid level of the original liquid in the liquid storage tank 12 is gradually reduced, so that the overall weight of the liquid storage tank 12 is gradually reduced, and then the overall weight of the heating shell 11 and other parts connected to it is gradually reduced. At this time, the pressure on the spring in the liquid storage shell 2 is gradually reduced, so as to drive the fixed column 21 to gradually reset upward, and the hydraulic oil in the multi-stage telescopic rod 22 is pumped into the liquid storage shell 2, and the fixed column 21 is used to adjust the hydraulic pressure of the spring. The column 21 drives the heating shell 11 and other parts connected thereto to reset upward synchronously, and at the same time, the telescopic end of the multi-stage telescopic rod 22 drives the sealing ring 16 to gradually move downward (the specific movement process is opposite to the upward movement process of the sealing ring 16), so that the height of the sealing ring 16 is synchronously reduced as the liquid level in the liquid storage tank 12 decreases, thereby changing the volume of hot air stored between the heating shell 11 and the liquid storage tank 12, and then changing the heating position of the liquid storage tank 12, heating the volume of the raw liquid in the liquid storage tank 12, and avoiding wasting hot air.

[0032] Until the liquid level of the original liquid in the liquid storage tank 12 drops to a certain height (the original liquid in the liquid storage tank 12 is in a solid-liquid mixed state, and at this time, it is no longer necessary to continue to heat the liquid storage tank 12 through an external heat source. The remaining solid enzyme in the original liquid can be precipitated by relying solely on the residual heat in the liquid storage tank 12. At the same time, it can also avoid the solid enzyme in the original liquid from accumulating on the lower side of the liquid storage tank 12, causing the solid enzyme to be inactivated by heat), the control terminal shuts down the hot air pump 14. After the original liquid in the liquid storage tank 12 is cooled, the control terminal shuts down the vacuum pump and opens the drain pipe 18 at the same time to release the solid-liquid mixture in the liquid storage tank 12 for the next operation, and cleans the remaining parts in the liquid storage tank 12 for next use.

[0033] In the present embodiment, the connecting frame 35 and the connecting shaft 31 are fixedly connected, and in Example 4, the connecting frame 35 and the connecting shaft 31 are rotatably connected via the connecting shell 6; at the same time, in the present embodiment, the lower part of the liquid storage tank 12 is a conical bottom, but in Example 3, the liquid storage tank 12 is a circular tube, and its lower part is not sealed, and in Example 3, the conical bottom 5 is used to seal the liquid storage tank 12; at the same time, in the present embodiment, the sealing tube 311 and the connecting shaft 31 are sealed and rotatably connected, and in Example 4, the sealing tube 311 is sealed and rotatably connected to the connecting shaft 31 via the connecting shell 6.

[0034] Embodiment 2: Considering that only the side wall and bottom of the container are heated during the current heating process, the stock solution at the center of the container is heated relatively slowly, which affects the evaporation rate of the stock solution. In this regard, this problem is solved in the following manner in this embodiment: Based on Example 1, please refer to Figure 2-Figure 5Reading this paragraph, it also includes a second gas pipe 4, which is fixedly connected and communicated with the hot air pump 14, and the connecting shaft 31 is provided with a cavity. The other end of the second gas pipe 4 is rotatably connected to the connecting shaft 31 and communicated with the cavity of the connecting shaft 31. The hot air pump 14 transports hot air to the cavity of the connecting shaft 31 through the second gas pipe 4 to heat the inside of the original liquid in the liquid storage tank 12. The connecting shaft 31 is provided with multiple groups of exhaust holes 41 distributed evenly at intervals, and each group of exhaust holes 41 includes four exhaust holes evenly distributed in the circumferential direction. A one-way valve (an existing device, not shown in the figure) is provided in the exhaust hole 41. The one-way valve in the exhaust hole 41 can only transport gas from the cavity of the connecting shaft 31 to the outside. The exhaust hole 41 is connected to the cavity of the connecting shaft 31. The hot gas transported to the connecting shaft 31 is discharged synchronously through multiple groups of exhaust holes 41, and the inside of the original liquid in the liquid storage tank 12 is blown outward to increase the heat exchange efficiency. A plurality of axially distributed fixed shells 42 are fixedly connected in the cavity of the connecting shaft 31. The specific number of the fixed shells 42 is the same as the specific number of groups of the above-mentioned exhaust holes 41. The fixed shells 42 are located on the upper side of the adjacent exhaust holes 41. The internal sealing sliding connection of the fixed shells 42 is a shielding ring 43. The shielding ring The shielding ring 43 is sealed and slidably connected with the inner wall of the cavity of the connecting shaft 31. The shielding ring 43 is used to shield the adjacent exhaust hole 41. In the initial position, the shielding ring 43 shields the adjacent exhaust hole 41. The figures all show the position of the shielding ring 43 after moving. The connecting shaft 31 is fixedly connected with a fixed pipe 44, and the fixed pipe 44 is filled with hydraulic oil. The fixed pipe 44 is connected to the adjacent fixed shell 42 through a connecting pipe. The upper end of the fixed pipe 44 passes through the connecting shaft 31, and the fixed pipe 44 is connected to the liquid storage shell 2 through a connecting pipe. The hydraulic oil in the liquid storage shell 2 is transported to the fixed part of the multi-stage telescopic rod 22. At the same time, it is also transported into the fixed tube 44 and into multiple fixed shells 42 to drive the adjacent shielding rings 43 to move. A first elastic member 45 is fixedly connected between the fixed shell 42 and the adjacent shielding ring 43. The first elastic member 45 is a tension spring. The first elastic member 45 is used to maintain the initial position of the adjacent shielding ring 43 and drive the moved shielding ring 43 to reset to the initial position. The elastic coefficient of the axially distributed first elastic member 45 increases as the distance between it and the sealing cover 13 decreases, ensuring that the multiple shielding rings 43 after moving follow the order from top to bottom during the resetting process.

[0035] While the hydraulic oil in the above-mentioned liquid storage shell 2 is transported to the fixed part of the multi-stage telescopic rod 22 through the connecting pipe, the hydraulic oil in the liquid storage shell 2 is also transported to the fixed pipe 44 through the connecting pipe, and the hydraulic oil transported to the fixed pipe 44 is transported to the adjacent fixed shell 42 through the connecting pipe. The following description takes the change of the volume of the hydraulic oil in the uppermost fixed shell 42 as an example: The hydraulic oil delivered to the fixed shell 42 causes the shielding ring 43 to move upward along the adjacent fixed shell 42, and causes the adjacent first elastic member 45 to be stretched and force is stored. During the upward movement of the shielding ring 43, the gradual movement of the shielding ring 43 causes the four adjacent exhaust holes 41 to be gradually released, until the shielding ring 43 moves upward to the extreme position, and the four adjacent exhaust holes 41 are synchronously restored to the maximum flow area. The remaining upward movement processes of the shielding ring 43 can refer to the above.

[0036] In the above-mentioned process of heating the raw liquid in the liquid storage tank 12, the hot air pump 14 not only transports hot air to the first air pipe 15, but also transports hot air to the second air pipe 4, and then transports hot air to the cavity of the connecting shaft 31. The hot air transported to the cavity of the connecting shaft 31 is discharged into the liquid storage tank 12 through the exhaust hole 41, and then blows the raw liquid in the liquid storage tank 12, so that the raw liquid in the liquid storage tank 12 moves away from the connecting shaft 31, mixes with the raw liquid away from the connecting shaft 31, and further increases the uniformity of heating of the raw liquid in the liquid storage tank 12.

[0037] During the process of resetting the above-mentioned fixed column 21 to the initial position, the hydraulic oil delivered to the fixed pipe 44 is synchronously pumped back into the liquid storage shell 2, and the hydraulic oil in the fixed shell 42 is synchronously pumped outward, thereby reducing the tension on the adjacent first elastic member 45, so that the shielding ring 43 moves downward under the action of the adjacent first elastic member 45, and the shielding ring 43 re-shields the four adjacent exhaust holes 41. In this process, since the elastic force of the axially distributed first elastic member 45 gradually increases from bottom to top, the shielding ring 43 gradually moves from top to bottom during its downward movement, that is, in the process of blocking the axially distributed exhaust holes 41, it is blocked from top to bottom simultaneously, thereby reducing the height of the hot air ejected from the axially distributed exhaust holes 41, further reducing the waste of hot air.

[0038] After the required solid-liquid mixture is prepared according to the above operation, the control terminal shuts down the above device and releases the solid-liquid mixture for subsequent operations, and cleans the parts in the liquid storage tank 12 for next use.

[0039] Example 3: Considering that after the solid enzyme precipitates from the stock solution in the container, the solid enzyme will sink to the bottom of the container to form an accumulation. At this time, when the bottom of the container is heated, the solid enzyme accumulated at the bottom of the container affects the thermal conductivity of the container, causing the evaporation rate of the stock solution in the container to decrease. At the same time, the solid enzyme accumulated at the bottom of the container may be locally heated, and even cause the heated solid enzyme to be inactivated, affecting the final quality of the enzyme preparation. In this regard, this problem is solved in the following way in this example: Based on Example 2, please refer to Figure 6 and Figure 7Reading this paragraph, it also includes a conical bottom 5, which is sealed and slidably connected to the lower side of the liquid storage tank 12, and the conical bottom 5 is sealed and slidably connected to the drain pipe 18 to prevent the original liquid in the liquid storage tank 12 from leaking outward during the movement of the conical bottom 5. An air guide groove 51 is arranged on the conical bottom 5, and the air guide groove 51 is connected to the heating shell 11. The air guide groove 51 is used to guide the hot air at the lower part of the heating shell 11 to increase the heating efficiency of the bottom of the original liquid in the liquid storage tank 12. An electric telescopic rod 52 electrically connected to the control terminal is installed on the lower side of the heating shell 11. The telescopic end of the electric telescopic rod 52 passes through the heating shell 11 and is fixedly connected to the lower side of the conical bottom 5. The conical bottom 5 is driven downward by the telescopic end of the electric telescopic rod 52. The upper side of the conical bottom 5 is provided with eight groups of air guide holes 53 evenly distributed in the circumferential direction, and each group of air guide holes 53 includes There are several air guide holes 53 in a linear array, which are connected to the air guide groove 51, and are used to guide the hot air flowing into the air guide groove 51 into the liquid storage tank 12 to directly contact the raw liquid in the liquid storage tank 12, and blow the solid enzyme precipitated in the liquid storage tank 12 upward. The air guide hole 53 is conical, and the diameter of the lower side of the air guide hole 53 is smaller than the diameter of the upper side thereof, which is used to increase the coverage of the hot air blown out by the air guide hole 53, so that the raw liquid in the liquid storage tank 12 is heated more evenly. A pressure valve (an existing device, not shown in the figure) is provided in the air guide hole 53 to prevent the raw liquid from flowing into the air guide groove 51. A sealing ring 54 is fixedly connected to the lower side of the liquid storage tank 12, and the sealing ring 54 is in contact with and cooperates with the conical bottom 5. The sealing ring 54 is fixedly connected to the drain pipe 18, and the sealing ring 54 is in contact with and cooperates with the air guide hole 53, so as to seal the air guide hole 53.

[0040] When solid enzyme begins to precipitate from the original liquid in the above-mentioned liquid storage tank 12, the control terminal starts the electric telescopic rod 52, and the telescopic end of the electric telescopic rod 52 drives the conical bottom 5 to move slowly downward, so that the conical bottom 5 gradually loses contact with the sealing ring 54 and the distance between the two is slowly increased. At this time, the eight groups of air guide holes 53 are gradually released, and the hot air transported to the heating shell 11 flows into the air guide groove 51. At the same time, the distance between the conical bottom 5 and the heating shell 11 gradually decreases, so that the pressure of the hot air between the conical bottom 5 and the heating shell 11 gradually increases, and then the pressure of the hot air flowing into the air guide groove 51 gradually increases. At this time, the hot air with increased pressure pushes up the pressure valve in the eight groups of air guide holes 53, so that the pressure valve no longer blocks the adjacent air guide holes 53.

[0041] When the pressure valve does not block the adjacent air guide holes 53, the hot air flowing into the air guide groove 51 flows along the eight groups of air guide holes 53 into the liquid storage tank 12, blowing the stock liquid at the bottom of the liquid storage tank 12 upward, so that the stock liquid at the bottom of the liquid storage tank 12 is mixed with the stock liquid at the top, thereby increasing the uniformity of heating of the stock liquid in the liquid storage tank 12, and at the same time blowing the solid enzyme in the stock liquid upward to prevent the solid enzyme in the stock liquid from accumulating downward on the conical bottom 5, causing the solid enzyme to be inactivated by heat, thereby affecting the quality of the prepared enzyme preparation.

[0042] After the amount of solid enzyme precipitated from the stock liquid in the liquid storage tank 12 reaches a certain level (i.e., after the liquid level of the stock liquid in the above-mentioned liquid storage tank 12 drops to a certain height), the control terminal reversely starts the electric telescopic rod 52, and the telescopic end of the electric telescopic rod 52 drives the conical bottom 5 to reset to the initial position, until the conical bottom 5 is reset to the initial position, the control terminal simultaneously shuts down the electric telescopic rod 52 and the hot air pump 14, and the residual heat of the stock liquid in the liquid storage tank 12 precipitates the remaining solid enzyme in the stock liquid, until the stock liquid in the liquid storage tank 12 returns to room temperature, the control terminal opens the solenoid valve on the discharge pipe 18, releases the solid-liquid mixture in the liquid storage tank 12, and cleans other parts in the liquid storage tank 12 for next use.

[0043] Example 4: Considering that when the solid enzyme begins to precipitate from the stock solution, if the temperature of the heat source is maintained unchanged or increased, the precipitation rate of the solid enzyme can be increased, but this is likely to cause heat waste, and the precipitated solid enzyme is also easily affected by the heat source and inactivated. In this regard, this problem is solved in the following way in this example: Based on Example 3, please refer to Figure 2-Figure 4 , Figure 8 and Fig. 9Reading this paragraph, it also includes a connecting shell 6, the connecting shell 6 is sealed and rotatably connected to the lower end of the connecting shaft 31, the connecting shell 6 is sealed and rotatably connected to the sealing tube 311, and the two connecting frames 35 are fixedly connected to the connecting shell 6. The interior of the connecting shell 6 is fixedly connected to a connecting rod 61 that is sealed and rotatably connected to the connecting shaft 31, and the connecting shaft 31 is fixedly connected to a fixing rod 62 that is sealed and rotatably connected to the connecting shell 6. A second elastic member 63 is arranged on the opposite side of the fixing rod 62 and the connecting rod 61. The second elastic member 63 is an arc spring. The second elastic member 63 is used to maintain the distance between the connecting rod 61 and the fixing rod 62, and the connecting shaft 31 passes through the fixing rod 62 and the connecting rod 61. The common transmission of the connecting rod 61 and the second elastic member 63 drives the connecting shell 6 to rotate synchronously. The connecting shaft 31 and the connecting shell 6 are filled with hydraulic oil between the opposite sides of the fixed rod 62 and the connecting rod 61. A liquid storage ring 64 is fixedly connected to the lower side of the discharge pipe 18. The interior of the liquid storage ring 64 is filled with hydraulic oil. The internal sealing and rotational connection of the liquid storage ring 64 is connected to a connecting ring 65. The liquid storage ring 64 and the connecting ring 65 form a liquid storage cavity. A connecting pipe connected to the liquid storage cavity is fixedly connected between the connecting ring 65 and the connecting shell 6. The connecting shell 6 drives the connecting ring 65 to rotate synchronously during the rotation process. A liquid storage pipe 66 is fixedly connected to the lower part of the front side of the bracket 1. 66 is connected to the liquid storage chamber through a connecting pipe, and the connecting rod 61 is driven by the connecting shell 6 to squeeze the hydraulic oil between it and the fixed rod 62 into the liquid storage ring 64, and is transported to the liquid storage pipe 66 through the transfer of the liquid storage ring 64. A pressure detector electrically connected to the control terminal is fixedly connected to the inside of the liquid storage pipe 66, and a push plate 67 is slidably connected to the inside of the liquid storage pipe 66. A third elastic member 68 is fixedly connected between the push plate 67 and the pressure detector. The third elastic member 68 is a spring. The third elastic member 68 is used to maintain the initial position of the push plate 67 and drive the push plate 67 to reset to the initial position after moving. The hydraulic oil transported to the liquid storage pipe 66 causes the push plate 67 to return to the initial position. The disk 67 moves to the left, causing the third elastic member 68 to compress and store force. A solenoid valve (an existing device, not shown in the figure) electrically connected to the control terminal is provided at the connection point between the liquid storage pipe 66 and the adjacent connecting pipe. In the initial state, the solenoid valve on the liquid storage pipe 66 is in a closed state. At this time, the hydraulic oil in the liquid storage ring 64 cannot be transported to the liquid storage pipe 66. The connecting shaft 31 and the connecting shell 6 can be regarded as fixedly connected. The connection points between the first gas pipe 15 and the second gas pipe 4 and the hot air pump 14 are both provided with a solenoid valve (an existing device, not shown in the figure) electrically connected to the control terminal, which is used to change the flow area of ​​the first gas pipe 15 and the second gas pipe 4.

[0044] After the solid enzyme begins to precipitate from the stock solution in the above-mentioned liquid storage tank 12, the control terminal opens the solenoid valve on the liquid storage tube 66. At this time, the liquid storage ring 64 and the liquid storage tube 66 are in a connected state. Although the precipitated solid enzyme is blown upward by the hot air discharged from the above-mentioned air guide hole 53, the solid enzyme still floats in the lower part of the liquid storage tank 12 due to the physical factors of the solid enzyme itself. At this time, the connecting shaft 31 drives the two connecting frames 35 and the stirring blades 36 on the two to rotate. The resistance of the connecting frame 35 and the stirring blades 36 on the two increases synchronously with the increase of the amount of solid enzyme precipitation, thereby causing the two connecting frames 35 and the stirring blades on the two to rotate. The mixing blade 36 rotates relative to the connecting shaft 31 under the action of the solid enzyme resistance. During this process, the two connecting frames 35 jointly drive the connecting shell 6 to rotate synchronously, and the connecting shell 6 drives the connecting rod 61 to rotate synchronously, so that the second elastic member 63 is compressed and stores force, and the hydraulic oil between the connecting rod 61 and the fixed rod 62 is transported to the liquid storage ring 64 through the connecting pipe. At the same time, the hydraulic oil is transported to the liquid storage pipe 66 through the connecting pipe by the liquid storage ring 64, so that the push plate 67 is pushed by the hydraulic oil to move to the left, and the third elastic member 68 is compressed and stores force, and at the same time, the value detected by the pressure detector in the liquid storage pipe 66 gradually increases.

[0045] When the value detected by the above-mentioned pressure detector gradually increases, the control terminal changes the flow area of ​​the electromagnetic valve on the first gas pipe 15 and the second gas pipe 4, reduces the volume of hot air transported to the first gas pipe 15 and the second gas pipe 4 per unit time, and reduces the precipitation rate of the solid enzyme in the stock solution in the liquid storage tank 12, so as to avoid that after the solid enzyme begins to precipitate from the stock solution in the liquid storage tank 12, the initial heating temperature is still maintained, which causes the stock solution in the liquid storage tank 12 to overheat, thereby affecting the precipitated solid enzyme and even affecting the activity of the prepared enzyme preparation. When a large amount of solid enzyme begins to precipitate in the liquid storage tank 12, the control terminal shuts down the hot air pump 14 according to the above operation, and uses the residual heat in the liquid storage tank 12 to continue to evaporate the remaining stock solution until the stock solution in the liquid storage tank 12 returns to room temperature. The control terminal releases the solid-liquid mixture in the liquid storage tank 12 and cleans other parts in the liquid storage tank 12 for next use.

[0046] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and its improved conception, which should be covered by the protection scope of the present application.
