In order to facilitate the industrial application of enzymes, the enzyme-containing liquid (hereinafter referred to as the original liquid) needs to be concentrated and refined. Since enzymes are active substances and are sensitive to temperature, the original liquid is usually added to a closed container and evaporated under negative pressure during concentration. However, the heating plate of the current heating device is always maintained at the same height, and as the heating time gradually increases, the volume of the original liquid in the closed container continuously decreases, and the liquid level continuously decreases.

[0032] Please refer to Figure 2 and Figure 3Reading this paragraph, the lower side of the support 1 is fixed with a liquid storage shell 2, the liquid storage shell 2 is filled with hydraulic oil, the lower side of the heating shell 11 is fixed with a fixed column 21, the fixed column 21 slides in the inside of the liquid storage shell 2, the fixed column 21 is used for extruding the hydraulic oil in the liquid storage shell 2 outward, the spring is fixed between the liquid storage shell 2 and the fixed column 21, which is used 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 fixed with a multi-stage telescopic rod 22, the fixed part of the multi-stage telescopic rod 22 is communicated with the liquid storage shell 2 through the connecting pipe, the hydraulic oil in the liquid storage shell 2 is transported to the fixed part of the multi-stage telescopic rod 22 through the connecting rod by the fixed column 21, so as to drive the telescopic end of the multi-stage telescopic rod 22 to move upward, the telescopic part of the multi-stage telescopic rod 22 penetrates through the heating shell 11 and is slidably connected with the heating shell 11, the telescopic end of the multi-stage telescopic rod 22 is fixed with the sealing ring 16, and the sealing ring 16 is driven to move synchronously by the telescopic end of the multi-stage telescopic rod 22, so as to change the volume between the heating shell 11 and the liquid tank 12.

[0033] Please refer to Figures 2-4 Reading this paragraph, the lower side of the support 1 is fixed with a liquid storage shell 2, the liquid storage shell 2 is filled with hydraulic oil, the lower side of the heating shell 11 is fixed with a fixed column 21, the fixed column 21 slides in the inside of the liquid storage shell 2, the fixed column 21 is used for extruding the hydraulic oil in the liquid storage shell 2 outward, the spring is fixed between the liquid storage shell 2 and the fixed column 21, which is used 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 fixed with a multi-stage telescopic rod 22, the fixed part of the multi-stage telescopic rod 22 is communicated with the liquid storage shell 2 through the connecting pipe, the hydraulic oil in the liquid storage shell 2 is transported to the fixed part of the multi-stage telescopic rod 22 through the connecting rod by the fixed column 21, so as to drive the telescopic end of the multi-stage telescopic rod 22 to move upward, the telescopic part of the multi-stage telescopic rod 22 penetrates through the heating shell 11 and is slidably connected with the heating shell 11, the telescopic end of the multi-stage telescopic rod 22 is fixed with the sealing ring 16, and the sealing ring 16 is driven to move synchronously by the telescopic end of the multi-stage telescopic rod 22, so as to change the volume between the heating shell 11 and the liquid tank 12.

[0034] In the process of using the device, the sealing cover 13 is first opened by the staff, and then the raw liquid is injected into the liquid storage tank 12. When the liquid level in the liquid storage tank 12 is flush with the upper side of the fixed frame 34, the staff stops injecting the raw liquid into the liquid storage tank 12, and then the sealing cover 13 is reinstalled on the upper side of the liquid storage tank 12.

[0035] In the above process of injecting raw liquid into the liquid storage tank 12, as the volume of the raw liquid in the liquid storage tank 12 gradually increases, the overall weight of the liquid storage tank 12 also gradually increases, thereby gradually increasing the overall weight of the heating shell 11 and its internal parts, causing the liquid storage tank 12 to gradually move downward along the support 1 with the heating shell 11 and other parts connected thereto, and the liquid storage tank 12 to move downward along the first gear 32 with the connecting shaft 31, and the heating shell 11 to move downward synchronously with the multi-stage telescopic rod 22 and other parts connected thereto.

[0036] In the process of moving the heating shell 11 downward, the heating shell 11 moves synchronously downward with the fixed column 21 along the liquid storage shell 2, causing the spring inside the liquid storage shell 2 to compress and store energy, and the hydraulic oil in the liquid storage shell 2 to be squeezed into the fixed part of the multi-stage telescopic rod 22 through the connecting pipe by the fixed column 21, causing the telescopic end of the multi-stage telescopic rod 22 to move upward, thereby causing the sealing ring 16 to move upward, to change the volume between the heating shell 11, the liquid storage tank 12 and the sealing ring 16, and to change the heating area of the liquid storage tank 12.

[0037] Until the above-mentioned stop injecting raw liquid into the liquid storage shell 2, the heating shell 11 and other parts connected thereto move downward to the limit position, and 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 on the upper side of the fixed frame 34), and then the control terminal starts the air pump to extract the air in the liquid storage tank 12 through the exhaust pipe 131, so that the inside of the liquid storage tank 12 is in a negative pressure state.

[0038] After the above-mentioned extraction of air in the liquid storage tank 12, the control terminal starts the hot gas pump 14 and the driving motor 3, and the hot gas pump 14 outputs hot gas through the first gas pipe 15 into the heating shell 11 to heat the liquid storage tank 12, so that the raw liquid in the liquid storage tank 12 is heated, and the steam generated by the heating of the raw liquid in the liquid storage tank 12 is extracted by the air pump and flows outward along the exhaust pipe 131, ensuring that the inside 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 gas outlet pipe on the upper side of the sealing ring 16.

[0039] After the control terminal starts the driving motor 3, the output shaft of the driving motor 3 drives the connecting shaft 31 through the transmission of the second gear 33 and the first gear 32, the connecting shaft 31 drives the two fixed frames 34 and the two connecting frames 35 on it to rotate synchronously, the two fixed frames 34 and the two connecting frames 35 drive the adjacent stirring blades 36 to rotate synchronously, and the left stirring blade 36 pushes the raw liquid in the liquid storage tank 12 close to the connecting shaft 31 to the direction away from the connecting shaft 31, and the right stirring blade 36 pushes the raw liquid in the liquid storage tank 12 away from the connecting shaft 31 to the direction close to the connecting shaft 31 (taking the perspective of the left and right sides as an example), so that the raw liquid in the liquid storage tank 12 is evenly heated, the evaporation speed of the raw liquid in the liquid storage tank 12 is increased, the temperature of the hot gas 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 gas pump 14 according to the value of the temperature detector to realize automatic regulation and control of the temperature. Figure 3

[0040] In the above process of heating and evaporating the raw liquid in the liquid storage tank 12, as the water in the raw liquid in the liquid storage tank 12 is gradually evaporated, the volume of the raw liquid in the liquid storage tank 12 gradually decreases, that is, the liquid level of the raw liquid in the liquid storage tank 12 gradually decreases, so that the total weight of the liquid storage tank 12 gradually decreases, and then the total weight of the heating shell 11 and other parts connected thereto gradually decreases. At this time, the pressure on the spring in the liquid storage shell 2 gradually decreases to drive the fixed column 21 to gradually reset upward, the hydraulic oil in the multi-stage telescopic rod 22 is drawn into the liquid storage shell 2, and the heating shell 11 and other parts connected thereto are driven by the fixed column 21 to reset upward synchronously. At the same time, the sealing ring 16 is driven by the telescopic end of the multi-stage telescopic rod 22 to gradually move downward (the specific movement process is opposite to the above-mentioned upward movement process of the sealing ring 16), so that the height of the sealing ring 16 decreases synchronously with the decrease of the liquid level of the raw liquid in the liquid storage tank 12, the volume of the stored hot gas between the heating shell 11 and the liquid storage tank 12 is changed, and then the heating position of the liquid storage tank 12 is changed. The volume of the raw liquid in the liquid storage tank 12 is heated to avoid waste of hot gas.

[0041] Until the liquid level of the raw liquid in the liquid storage tank 12 decreases to a certain height (the raw liquid in the liquid storage tank 12 is in a solid-liquid mixed state, at this time, the liquid storage tank 12 does not need to be continuously heated by an external heat source, but only relies on the residual heat in the liquid storage tank 12 to make the remaining solid enzyme in the raw liquid precipitate, which can also avoid the accumulation of solid enzyme in the lower part of the liquid storage tank 12, resulting in the inactivation of the solid enzyme due to heating), the control terminal stops the hot gas pump 14, and after the raw liquid in the liquid storage tank 12 cools down, the control terminal closes the air pump and opens the liquid discharge pipe 18 to discharge the solid-liquid mixture in the liquid storage tank 12 for the next operation. The remaining parts in the liquid storage tank 12 are cleaned for next use.

[0042] ​In this embodiment, the connecting frame 35 is fixedly connected with the connecting shaft 31, in Embodiment 4, the connecting frame 35 is rotatably connected with the connecting shaft 31 through the connecting shell 6; meanwhile, in this embodiment, the lower part of the liquid storage tank 12 is a conical bottom, but in Embodiment 3, the liquid storage tank 12 is a circular tube, and the lower part is not sealed, in Embodiment 3, the conical bottom 5 is used to seal the liquid storage tank 12; meanwhile, in this embodiment, the sealing tube 311 is sealingly and rotatably connected with the connecting shaft 31, in Embodiment 4, the sealing tube 311 is sealingly and rotatably connected with the connecting shaft 31 through the connecting shell 6.

[0043] Embodiment 2: Considering that at present, in the process of heating the container, only the side wall and the bottom side of the container are heated, the raw liquid located at the center of the container is heated slowly, which affects the evaporation rate of the raw liquid, for this, in this embodiment, the problem is solved by the following way:

[0044] On the basis of Embodiment 1, please refer to Figures 2-5The second gas pipe 4 is connected with the heat pump 14 and communicates with the connecting shaft 31. The other end of the second gas pipe 4 is rotatably connected with the connecting shaft 31 and communicates with the cavity of the connecting shaft 31. The heat pump 14 sends hot gas to the cavity of the connecting shaft 31 through the second gas pipe 4, so as to heat the inside of the raw liquid in the liquid storage tank 12. A plurality of groups of exhaust holes 41 are equidistantly arranged on the connecting shaft 31. Each group of exhaust holes 41 includes four exhaust holes 41 which are uniformly distributed in the circumferential direction. A one-way valve (not shown in the figure) is arranged in each exhaust hole 41. The one-way valve in the exhaust hole 41 can only send gas from the cavity of the connecting shaft 31 to the outside. The exhaust hole 41 communicates with the cavity of the connecting shaft 31. The hot gas sent to the connecting shaft 31 is synchronously discharged to the outside through the plurality of groups of exhaust holes 41, so as to blow the inside of the raw liquid in the liquid storage tank 12 to the outside, thereby increasing the heat exchange efficiency. A plurality of fixed shells 42 are arranged in the cavity of the connecting shaft 31. The number of the fixed shells 42 is the same as the number of the groups of exhaust holes 41. The fixed shell 42 is located above the adjacent exhaust hole 41. A shielding ring 43 is sealingly and slidably connected in the inside of the fixed shell 42. The shielding ring 43 is sealingly 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. The shielding ring 43 shields the adjacent exhaust hole 41 in the initial position. The positions of the shielding ring 43 after moving are shown in the figure. The connecting shaft 31 is fixedly connected with a fixed pipe 44. The fixed pipe 44 is filled with hydraulic oil. The fixed pipe 44 communicates with the adjacent fixed shell 42 through a connecting pipe. The upper end of the fixed pipe 44 penetrates the connecting shaft 31. The fixed pipe 44 communicates with the liquid storage shell 2 through the connecting pipe. The hydraulic oil in the liquid storage shell 2 is sent to the fixed pipe 44 and the plurality of fixed shells 42 while being sent to the fixed part of the multi-stage telescopic rod 22, so as to drive the adjacent shielding ring 43 to move. A first elastic member 45 is arranged 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 reset the shielding ring 43 after moving. The elastic coefficient of the first elastic member 45 increases with the decrease of the distance between the first elastic member 45 and the sealing cover 13, so as to ensure that the plurality of shielding rings 43 after moving are reset in the order from top to bottom.

[0045] While the hydraulic oil in the liquid storage shell 2 is sent 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 sent to the fixed pipe 44 through the connecting pipe. The hydraulic oil sent to the fixed pipe 44 is sent to the adjacent fixed shell 42 through the connecting pipe. The change of the volume of the hydraulic oil in the uppermost fixed shell 42 is described as follows:

[0046] The hydraulic oil delivered into the fixed shell 42 makes the shielding ring 43 move upward along the adjacent fixed shell 42 and makes the adjacent first elastic member 45 be stretched and store force. During the upward movement of the shielding ring 43, the gradual movement of the shielding ring 43 makes the adjacent four exhaust holes 41 be gradually opened, until the shielding ring 43 moves to the limit position, the adjacent four exhaust holes 41 are simultaneously restored to the maximum flow area, and the upward movement of the remaining shielding rings 43 can be referred to the above.

[0047] During the above-mentioned heating of the raw liquid in the liquid storage tank 12, the hot gas pump 14 delivers hot gas into the first gas delivery pipe 15 and also delivers hot gas into the second gas delivery pipe 4, and then delivers hot gas into the cavity of the connecting shaft 31. The hot gas delivered into the cavity of the connecting shaft 31 is discharged into the liquid storage tank 12 through the exhaust holes 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 and mixes with the raw liquid away from the connecting shaft 31, further increasing the uniformity of the heating of the raw liquid in the liquid storage tank 12.

[0048] During the above-mentioned resetting of the fixed column 21 to the initial position, the hydraulic oil delivered into the fixed pipe 44 is simultaneously drawn back into the liquid storage shell 2, and the hydraulic oil in the fixed shell 42 is simultaneously drawn out, thereby reducing the tension on the adjacent first elastic member 45, making the shielding ring 43 move downward under the action of the adjacent first elastic member 45, and the shielding ring 43 re-shields the adjacent four exhaust holes 41. During this process, since the elastic force of the axially distributed first elastic members 45 gradually increases from bottom to top, the shielding ring 43 moves gradually from top to bottom during the downward movement, that is, during the shielding of the axially distributed exhaust holes 41, the shielding is simultaneously performed from top to bottom, thereby reducing the height of the hot gas ejected from the axially distributed exhaust holes 41, further reducing the waste of hot gas.

[0049] Until the required solid-liquid mixture is prepared by the above-mentioned operation, the control terminal stops the above-mentioned device, and the solid-liquid mixture is discharged for subsequent operation, and each part in the liquid storage tank 12 is cleaned for next use.

[0050] Example 3: Considering that after the raw liquid in the container precipitates solid enzyme, the solid enzyme will sink to the bottom of the container and accumulate, at this time, when the bottom of the container is heated, the accumulated solid enzyme at the bottom of the container affects the heat conductivity of the container, reducing the evaporation speed of the raw liquid in the container, and the solid enzyme accumulated at the bottom of the container may be locally heated, even causing the inactivated solid enzyme, affecting the final quality of the enzyme preparation. To solve this problem, the following method is used in this embodiment:

[0051] Based on example 2, please refer to Figure 6 and Figure 7The bottom 5 is sealingly and slidably connected to the lower side of the liquid storage tank 12, and sealingly and slidably connected to the liquid discharge pipe 18, so as to avoid the leakage of the original liquid in the liquid storage tank 12 during the movement of the conical bottom 5. The conical bottom 5 is provided with a gas guide groove 51 which is in communication with the heating shell 11, and the gas guide groove 51 is used to guide the hot gas at the lower part of the heating shell 11, so as to increase the heating efficiency of the bottom of the original liquid in the liquid storage tank 12. The lower side of the heating shell 11 is provided with an electric telescopic rod 52 which is electrically connected to the control terminal, and the telescopic end of the electric telescopic rod 52 penetrates through the heating shell 11 and is fixedly connected to the lower side of the conical bottom 5. The telescopic end of the electric telescopic rod 52 drives the conical bottom 5 to move downward, and the upper side of the conical bottom 5 is provided with eight groups of gas guide holes 53 which are uniformly distributed in a circumferential direction, each group of the gas guide holes 53 includes a plurality of straight-line arrays, the gas guide holes 53 are in communication with the gas guide groove 51, and are used to guide the hot gas flowing into the gas guide groove 51 to the liquid storage tank 12 to directly contact with the original liquid in the liquid storage tank 12, and blow the solid enzyme precipitated in the liquid storage tank 12 upward. The gas guide holes 53 are conical, and the diameter of the lower side of the gas guide holes 53 is smaller than that of the upper side, so as to increase the coverage range of the hot gas blown out of the gas guide holes 53, and make the heating of the original liquid in the liquid storage tank 12 more uniform. The gas guide holes 53 are provided with pressure valves (not shown in the figure), so as to avoid the flow of the original liquid into the gas guide groove 51. The lower side of the liquid storage tank 12 is fixedly connected to a blocking ring 54 which is in contact with the conical bottom 5, and the blocking ring 54 is fixedly connected to the liquid discharge pipe 18 and the gas guide holes 53, so as to seal the gas guide holes 53.

[0052] When the original liquid in the liquid storage tank 12 starts to precipitate the solid enzyme, 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 slowly move downward, so that the conical bottom 5 gradually loses contact with the blocking ring 54 and the distance between them slowly increases. At this time, the eight groups of gas guide holes 53 are gradually released, the hot gas transported into the heating shell 11 flows into the gas guide groove 51, and the distance between the conical bottom 5 and the heating shell 11 gradually decreases, so that the pressure of the hot gas between the conical bottom 5 and the heating shell 11 gradually increases, and then the pressure of the hot gas flowing into the gas guide groove 51 gradually increases. At this time, the pressure-increased hot gas lifts the pressure valves in the eight groups of gas guide holes 53 upward, so that the pressure valves no longer block the adjacent gas guide holes 53.

[0053] When the pressure valves no longer block the adjacent gas guide holes 53, the hot gas flowing into the gas guide groove 51 flows into the liquid storage tank 12 through the eight groups of gas guide holes 53, blows the original liquid at the bottom of the liquid storage tank 12 upward, mixes the original liquid at the bottom of the liquid storage tank 12 with the original liquid at the upper part, increases the uniformity of the heating of the original liquid in the liquid storage tank 12, and blows the solid enzyme in the original liquid upward, so as to avoid the solid enzyme in the original liquid from being accumulated on the conical bottom 5, which causes the solid enzyme to be inactivated by heating and affects the quality of the prepared enzyme preparation.

[0054] When the amount of solid enzyme in the stock solution in the storage tank 12 reaches a certain level (i.e. when the liquid level of the stock solution in the 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 return to the initial position. When the conical bottom 5 returns to the initial position, the control terminal simultaneously stops the electric telescopic rod 52 and the hot air pump 14. The residual heat of the stock solution in the storage tank 12 causes the remaining solid enzyme in the stock solution to precipitate. When the stock solution in the storage tank 12 returns to room temperature, the control terminal opens the electromagnetic valve on the liquid discharge pipe 18, discharges the solid-liquid mixture in the storage tank 12, and cleans other parts in the storage tank 12 for the next use.

[0055] In the embodiment 4, the problem is solved by the following method:

[0056] Based on the embodiment 3, please refer to Figures 2-4 , Figure 8 and Figure 9As read from this paragraph, the connecting shell 6 is sealingly and rotatably connected to the lower end of the connecting shaft 31. The connecting shell 6 is sealingly and rotatably connected to the sealing tube 311. The two connecting frames 35 are fixedly connected to the connecting shell 6. The interior of the connecting shell 6 is fixedly connected to the connecting rod 61 which is sealingly and rotatably connected to the connecting shaft 31. The connecting shaft 31 is fixedly connected to the fixed rod 62 which is sealingly and rotatably connected to the connecting shell 6. The second elastic member 63 is arranged on the side opposite to the connecting rod 61 of the fixed rod 62. 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 fixed rod 62. The connecting shaft 31 drives the connecting shell 6 to rotate synchronously through the common transmission of the fixed rod 62, the connecting rod 61 and the second elastic member 63. The connecting shaft 31 and the connecting shell 6 are filled with hydraulic oil between the side opposite to the connecting rod 61 of the fixed rod 62. The lower side of the liquid discharge pipe 18 is fixedly connected to the liquid storage ring 64. The interior of the liquid storage ring 64 is filled with hydraulic oil. The interior of the liquid storage ring 64 is sealingly and rotatably connected to the connecting ring 65. The liquid storage ring 64 and the connecting ring 65 form a liquid storage cavity. The connecting ring 65 and the connecting shell 6 are fixedly connected to the connecting pipe which communicates with the liquid storage cavity. The connecting shell 6 drives the connecting ring 65 to rotate synchronously in the process of rotation. The lower part of the front side of the support 1 is fixedly connected to the liquid storage pipe 66. The liquid storage pipe 66 communicates with the liquid storage cavity through the connecting pipe. The hydraulic oil between the connecting rod 61 and the fixed rod 62 is extruded to the liquid storage ring 64 by the connecting shell 6, and is transported to the liquid storage pipe 66 through the liquid storage ring 64. The interior of the liquid storage pipe 66 is fixedly connected to the pressure detector which is electrically connected to the control terminal. The interior of the liquid storage pipe 66 is slidingly connected to the push disc 67. The push disc 67 and the pressure detector are fixedly connected to the third elastic member 68. The third elastic member 68 is a spring. The third elastic member 68 is used to maintain the initial position of the push disc 67 and drive the push disc 67 to reset to the initial position after movement. The hydraulic oil transported to the liquid storage pipe 66 makes the push disc 67 move to the left, and the third elastic member 68 is compressed to store energy. The communication part of the liquid storage pipe 66 and the adjacent connecting pipe is provided with the electromagnetic valve which is electrically connected to the control terminal (it is an existing device and is not shown in the figure). The electromagnetic valve on the liquid storage pipe 66 is in the closed state in the initial 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 communication parts of the first gas conveying pipe 15 and the second gas conveying pipe 4 and the heat gas pump 14 are provided with the electromagnetic valves which are electrically connected to the control terminal (they are existing devices and are not shown in the figure), which are used to change the flow area of the first gas conveying pipe 15 and the second gas conveying pipe 4.

[0057] When the solid enzyme begins to precipitate in the liquid in the liquid storage tank 12, the control terminal opens the electromagnetic valve on the liquid storage pipe 66, and the liquid storage ring 64 is in communication with the liquid storage pipe 66. The precipitated solid enzyme is moved upward by the hot air blown from the air outlet hole 53, but due to the physical factors of the solid enzyme, the solid enzyme still floats in the lower part of the liquid storage tank 12. In this process, the connecting shaft 31 drives the two connecting frames 35 and the stirring blades 36 on them to rotate, and the resistance of the connecting frames 35 and the stirring blades 36 on them increases synchronously with the increase of the amount of precipitated solid enzyme, and then the two connecting frames 35 and the stirring blades 36 on them rotate relative to the connecting shaft 31 under the action of the resistance of the solid enzyme. In this process, the two connecting frames 35 drive the connecting shell 6 to rotate synchronously, the connecting shell 6 drives the connecting rod 61 to rotate synchronously, the second elastic member 63 is compressed and stored, 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, and at the same time, the hydraulic oil is transported to the liquid storage pipe 66 through the connecting pipe from the liquid storage ring 64, so that the push disc 67 is pushed to the left by the hydraulic oil, the third elastic member 68 is compressed and stored, and the value detected by the pressure detector in the liquid storage pipe 66 gradually increases.

[0058] When the value detected by the pressure detector gradually increases, the control terminal changes the flow area of the electromagnetic valves on the first gas conveying pipe 15 and the second gas conveying pipe 4, reduces the volume of hot air conveyed into the first gas conveying pipe 15 and the second gas conveying pipe 4 per unit time, and reduces the precipitation speed of the solid enzyme in the liquid in the liquid storage tank 12. When the liquid in the liquid storage tank 12 begins to precipitate solid enzyme, the initial heating temperature is maintained, which causes the liquid in the liquid storage tank 12 to overheat, which affects the precipitated solid enzyme, and even affects 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 stops the hot air pump 14 according to the above operation, continues to evaporate the remaining liquid by using the residual heat in the liquid storage tank 12, and releases the solid-liquid mixture in the liquid storage tank 12 after the liquid in the liquid storage tank 12 returns to room temperature. The other parts in the liquid storage tank 12 are cleaned for next use.

[0059] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and improvement concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
