Description

Technical Field

[0001] The invention relates to the technical field of heat treatment of grape puree, in particular to a time control device for heat treatment of grape puree and a sterilization process thereof. Background Art

[0002] Grape puree heat treatment is a common sterilization method that kills microorganisms in grape puree, including yeast, bacteria and mold, by high temperature, thereby ensuring the quality and stability of the wine. Proper heat treatment can effectively reduce the number of these microorganisms and prevent them from having adverse effects during subsequent fermentation and storage.

[0003] However, during the stirring process, if the temperature of the inner wall of the stirring barrel is higher than that of the grape puree, or there is residue on the inner wall, the grape puree will heat up rapidly and adhere to the inner wall when it contacts the inner wall. This adhesion phenomenon will further affect the stirring effect, making the flow of the grape puree in the stirring barrel more uneven, thereby causing uneven stirring preheating. When the grape puree is heated unevenly during the stirring process, the gas therein (such as air or other gases dissolved in the grape puree) may precipitate due to the increase in temperature to form bubbles. The presence of bubbles in the grape puree will interfere with the accurate reading of the temperature sensor, because the gas in the bubbles has different thermal conductivity from the liquid, and the temperature around the bubbles may be different from the actual liquid temperature, which will cause the temperature measured by the temperature sensor to be too high or too low, thereby affecting the accurate control of the preheating time.

[0004] In addition, the stirring rods of the existing grape puree are all stirred at a fixed height. Since the position and angle of the stirring rods are fixed, they cannot be flexibly adjusted according to changes in the viscosity, temperature, volume, etc. of the grape puree, which may cause uneven stirring. Uneven stirring will affect the mixing effect of the grape puree, which will again affect the accurate control of the preheating time. At the same time, the physical and chemical properties of the grape puree may be different in different production batches. If the stirring rod cannot be adjusted, it will be difficult to adapt to these changes, resulting in unstable stirring effect, which will increase uncertainty in the production process and reduce production efficiency.

[0005] Therefore, a grape puree heat treatment time control device and a sterilization process thereof are proposed to solve the above problems. Summary of the invention

[0006] In view of this, the technical problem to be solved by the present invention is to propose a grape puree heat treatment time control device and a sterilization process thereof to solve the problems of uneven preheating stirring and the inability of the stirring rod to adapt to stirring at different heights in the prior art.

[0019] A grape puree heat treatment time-controlled sterilization process comprises the following steps:

[0020] Step 1: Pretreatment: Before heat treatment, the grape puree should be pretreated, such as filtering and removing impurities, to remove impurities and microorganisms;

[0021] Step 2: heating treatment: placing the grape puree in a heat treatment device and performing heating treatment according to preset temperature and time parameters; the heating temperature and time should be determined according to the type of grape puree, the initial microbial content and the required sterilization effect;

[0022] Step 3: Cooling: After the heat treatment is completed, the grape puree should be cooled quickly to prevent it from being heated and deteriorating;

[0023] Step 4: Quality testing: After the heat treatment, the grape puree should be tested for quality, including microbial content, physical and chemical indicators, etc., to ensure that it meets the relevant standards and requirements.

[0024] Compared with the prior art, the present invention provides a grape puree heat treatment time control device and a sterilization process thereof, which have the following beneficial effects:

[0025] 1. The multifunctional stirring and cleaning mechanism can ensure that the grape puree is evenly distributed in the stirring barrel, reduce the temperature gradient, and transfer the heat to the entire grape puree more quickly. The traditional stirring method cannot fully remove the raw material residues on the inner wall of the stirring barrel. These residues are easy to form lumps or thermal resistance layers, which hinder the effective transfer of heat. The multifunctional stirring and cleaning mechanism not only has excellent stirring effect, but also has the function of scraping the inner wall of the stirring barrel. This innovative design can effectively prevent the raw materials from forming lumps or thermal resistance layers on the barrel wall, significantly improve the heat transfer efficiency, enable heat to penetrate the grape puree more quickly, reduce the time and energy consumption required for preheating, and thus help shorten the preheating time and improve production efficiency.

[0026] 2. The reciprocating pressing mechanism is set by pressing the exhaust disk to slide back and forth on the inner wall of the preheating stirring chamber, so that the air pressure in the preheating stirring chamber is constantly changed. At this time, the bubbles overflowing from the original pulp will burst under the action of air pressure. Since the orifice provides an escape path for the bubbles, the accumulation of bubbles during the stirring process is reduced. The reduction of bubbles means that the stirring medium can flow and mix more smoothly, reducing the uneven stirring caused by bubble obstruction. The existing methods for removing bubbles include standing, centrifugal separation, etc., but these methods often require additional equipment or time to achieve bubble removal. By pressing the exhaust disk to slide back and forth on the inner wall of the preheating stirring chamber, not only can the pressure in the stirring barrel be directly changed during the stirring process, but also the bubbles can be quickly broken and released under the pressure change, thereby achieving efficient elimination of bubbles. This method not only simplifies the process flow, but also greatly improves the efficiency of bubble removal. When the grape original pulp is evenly stirred, the heat distribution inside it will be more uniform, which means that during the heat treatment process, the heat can be transferred to each part of the original pulp faster, thereby reducing the time required for the whole to reach the required sterilization temperature.

[0027] 3. Through the setting of the height-adjustable protection mechanism, the stirring device that can be adjusted up and down can be flexibly adjusted according to the actual conditions of the grape puree, such as viscosity, liquid level height, etc. This not only ensures that all parts of the grape puree can be fully mixed during the stirring process, thereby improving the uniformity of stirring, thereby increasing the accurate control of the preheating time, but also uniform stirring can also improve the texture and taste of the grape puree and improve the quality of the final product.

[0028] 4. By adjusting the position of the connecting fixed shaft, the best stirring area can be found according to the characteristics of the grape puree and the shape of the stirring barrel, which is conducive to achieving a more uniform stirring effect, improving the preheating efficiency, and thus shortening the preheating time. Compared with the existing technology, the connecting fixed shaft with adjustable position has higher flexibility than the stirring shaft with fixed position. It can be flexibly adjusted according to different production requirements and process conditions to achieve the best stirring effect and preheating efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0043] First embodiment

[0044] Please refer to Figures 1 to 7 As shown:

[0045] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a grape puree heat treatment time control device and a sterilization process thereof, comprising an operating table 1, a preheating and stirring chamber 11 is fixedly connected to the operating table 1, a puree feed port 12 is fixedly connected to the outer surface of the preheating and stirring chamber 11, a supporting slide plate 13 is slidably connected to the inner wall of the preheating and stirring chamber 11, a connecting fixed shaft 14 is fixedly connected to the middle of the supporting slide plate 13, and a reciprocating pressing mechanism 2, a multifunctional stirring and cleaning mechanism 3 and a height-adjustable protection mechanism 4 are also included, and the height-adjustable protection mechanism 4, the reciprocating pressing mechanism 2 and the multifunctional stirring and cleaning mechanism 3 are respectively arranged on the upper, middle and lower sides of the inner wall of the preheating and stirring chamber 11;

[0046] The reciprocating pressing mechanism 2 is used to discharge the excess gas inside the preheating and stirring chamber 11;

[0047] The multifunctional stirring and cleaning mechanism 3 is used for uniform stirring and cleaning of grape puree;

[0048] The height-adjustable protection mechanism 4 is used to prevent the preheating and stirring bin 11 from being deformed and damaged due to the low air pressure in the preheating and stirring bin 11;

[0049] The reciprocating pressing mechanism 2 includes a rotating disk 21, the middle part of which is rotatably connected to the bottom of the supporting sliding disk 13, an eccentric driving block 22 is rotatably connected to the eccentric driving block 22 at a side away from the supporting sliding disk 13, and an end of the eccentric driving block 22 away from the rotating disk 21 is fixedly connected to a T-shaped sliding gear plate 23, a tooth surface of the T-shaped sliding gear plate 23 is meshed with a meshing gear shaft 24, and a U-shaped guide clamping plate 25 is slidably connected to the non-tooth surface of the outer surface of the T-shaped sliding gear plate 23;

[0050] The U-shaped guide clamping plate 25 is rotatably connected to the outer surface of the connecting and fixing shaft 14, the middle of the meshing gear shaft 24 is rotatably connected to the outer surface of the connecting and fixing shaft 14 near the bottom of the U-shaped guide clamping plate 25, and the outer surface of the connecting and fixing shaft 14 is rotatably connected to the bottom of the meshing gear shaft 24 with a multifunctional extrusion cylinder 26, and the upper end of the multifunctional extrusion cylinder 26 is fixedly connected to the middle of the meshing gear shaft 24;

[0051] An extrusion groove 28 is provided on the outer surface of the multifunctional extrusion cylinder 26, an extrusion column 29 is slidably connected in the extrusion groove 28, a pressing exhaust disk 27 is fixedly connected to the bottom of the extrusion column 29, and the middle part of the pressing exhaust disk 27 is sleeved on the outer surface of the multifunctional extrusion cylinder 26;

[0052] Among them: the motor is installed on the upper surface of the support slide plate 13, and the motor drive shaft passes through the support slide plate 13 and is fixedly connected to the middle of the turntable 21. At this time, the turntable 21 starts to rotate in the same direction by rotating the support slide plate 13, pressing the outer section of the exhaust plate 27 to slide and connect to the inner wall of the preheating mixing chamber 11;

[0053] In the prior art, methods for removing bubbles include standing, centrifugal separation, etc., but these methods often require additional equipment or time to achieve bubble removal. Through the implementation of this embodiment, by pressing the exhaust disk 27 to set a reciprocating slide on the inner wall of the preheating stirring chamber 11, not only can the pressure in the stirring barrel be directly changed during the stirring process, but also the bubbles can be quickly broken and released under the pressure change, thereby achieving efficient elimination of bubbles. This method not only simplifies the process flow, but also greatly improves the efficiency of bubble removal. When the grape puree is evenly stirred, the heat distribution inside it will be more uniform, which means that during the heat treatment process, the heat can be transferred to each part of the puree more quickly, thereby reducing the time required for the whole to reach the required sterilization temperature.

[0054] For further examples, please refer to Figures 1 to 7 As shown:

[0055] The multifunctional stirring and cleaning mechanism 3 includes a connecting cylinder 31, the upper end of the connecting cylinder 31 is fixedly connected to the bottom end of the multifunctional extruding cylinder 26, the middle part of the connecting cylinder 31 is fixedly connected to the outer surface of the connecting fixed shaft 14, the outer surface of the connecting cylinder 31 is symmetrically fixedly connected with a scraper 32, the end of the scraper 32 away from the connecting cylinder 31 is in contact with the inner wall of the preheating stirring bin 11, and the outer surface of the bottom of the connecting cylinder 31 is fixedly connected with a first beveled tooth 33, and the first beveled tooth 33 is sleeved on the outer surface of the connecting fixed shaft 14;

[0056] The first beveled teeth 33 are meshed with beveled teeth 34, and a fixed rod is fixedly passed through the connecting and fixing shaft 14 near the lower part of the first beveled teeth 33. The beveled teeth 34 are symmetrically connected to the two ends of the fixed rod of the connecting and fixing shaft 14. The beveled teeth 34 are fixedly connected to the bubble removal stirring shaft 35 on the side away from the connecting and fixing shaft 14.

[0057] The lower side of the tooth surface of the beveled tooth 34 is meshed with a second beveled tooth 36, the inner wall of the non-tooth surface of the second beveled tooth 36 is rotatably connected to the connecting and fixing shaft 14, and the lower end of the second beveled tooth 36 is fixedly connected to a multifunctional stirring and cleaning shaft 37, and the inner wall of the multifunctional stirring and cleaning shaft 37 is rotatably connected to the connecting and fixing shaft 14;

[0058] The height-adjustable protection mechanism 4 includes an adjusting wheel 41, a threaded shaft 42 is fixedly connected to the middle of the adjusting wheel 41, the threaded shaft 42 is threadedly connected to the upper surface of the preheating and stirring bin 11, and the lower end of the threaded shaft 42 is rotatably connected to the upper end of the connecting fixed shaft 14;

[0059] The push exhaust disk 27 is symmetrically provided with arc exhaust holes, a bevel plug 43 is slidably connected to the arc exhaust hole on the lower surface of the push exhaust disk 27, a compression spring 44 is fixedly connected to the upper surface of the bevel plug 43, an exhaust cover 45 is fixedly connected to one end of the compression spring 44 away from the bevel plug 43, and the bottom of the exhaust cover 45 is fixedly connected to the upper surface of the push exhaust disk 27;

[0060] Wherein: the bubble removal stirring shaft 35 is composed of a triangular plate and a flow partition plate, and the flow partition plate is evenly provided with bubble holes;

[0061] In the prior art, the stirring rod of the grape puree is stirred at a fixed height during stirring. Since the position and angle of the stirring rod are fixed, it is impossible to flexibly adjust according to changes in the viscosity, temperature, volume, etc. of the grape puree, which may lead to uneven stirring. Uneven stirring will affect the mixing effect of the grape puree, thereby affecting the accurate control of the preheating time again. At the same time, in different production batches, the physical and chemical properties of the grape puree may be different. If the stirring rod cannot be adjusted, it is difficult to adapt to these changes, resulting in unstable stirring effect, which will increase uncertainty in the production process and reduce production efficiency. Compared with the prior art, through the implementation of this embodiment, by setting a stirring device that can be adjusted up and down, it can be flexibly adjusted according to the actual conditions of the grape puree, such as viscosity, liquid level height, etc., which not only ensures that all parts of the grape puree can be fully mixed during the stirring process, thereby improving the uniformity of stirring, thereby increasing the accurate control of the preheating time, but also uniform stirring can improve the texture and taste of the grape puree and improve the quality of the final product.

[0062] Second embodiment

[0063] A grape puree heat treatment time-controlled sterilization process comprises the following steps:

[0064] Step 1: Pretreatment: Before heat treatment, the grape puree should be pretreated, such as filtering and removing impurities, to remove impurities and microorganisms;

[0065] Step 2: heating treatment: placing the grape puree in a heat treatment device and performing heating treatment according to preset temperature and time parameters; the heating temperature and time should be determined according to the type of grape puree, the initial microbial content and the required sterilization effect;

[0066] Step 3: Cooling: After the heat treatment is completed, the grape puree should be cooled quickly to prevent it from being heated and deteriorating;

[0067] Step 4: Quality testing: After the heat treatment, the grape puree should be tested for quality, including microbial content, physical and chemical indicators, etc., to ensure that it meets relevant standards and requirements;

[0068] Everything in the above example works like this:

[0069] In the initial state: the motor is not started and the compression spring 44 is not stretched.

[0070] The following is the working process of the reciprocating pressing mechanism 2 for discharging the excess gas inside the preheating stirring chamber 11 and the multifunctional stirring and cleaning mechanism 3 for uniformly stirring and cleaning the grape puree:

[0071] Before preheating and sterilizing the grape puree, firstly, according to the preheating temperature of the grape puree, the grape puree is filled into the preheating stirring bin 11 through the puree feed port 12. At this time, the motor is started to rotate under the control of the operator. Because the motor is installed on the upper surface of the supporting slide plate 13, and the motor drive shaft passes through the supporting slide plate 13 and is fixedly connected to the middle of the turntable 21, the rotation of the supporting slide plate 13 will drive the turntable 21 to start rotating in the same direction. Because the rotation direction has the same effect, only the clockwise rotation of the motor is described. At this time, the clockwise rotation of the motor will drive the turntable 21 to start rotating clockwise in the same direction. Because the eccentric portion of the lower surface of the turntable 21 is rotationally connected to the eccentric drive block 22, as shown in FIG. Figure 3 As shown, at this time, because the T-shaped sliding gear plate 23 is fixedly connected to the end of the eccentric driving block 22 away from the turntable 21, when the turntable 21 rotates, its eccentric part, that is, the part where the center point does not overlap with the eccentric trajectory, will periodically approach and move away from the contact point of the T-shaped sliding gear plate 23. This periodic change makes the T-shaped sliding gear plate 23 slide back and forth along the preset trajectory after being acted upon by the turntable 21. At this time, since the T-shaped sliding gear plate 23 will drive the meshing gear shaft 24 to start rotating during the reciprocating motion, at this time, since the reciprocating motion effect of the T-shaped sliding gear plate 23 is the same, only the sliding of the T-shaped sliding gear plate 23 to the right is described;

[0072] At this time, when the T-shaped sliding gear plate 23 slides to the right, since the meshing gear shaft 24 and the tooth surface of the T-shaped sliding gear plate 23 are meshed with each other, and the non-tooth surface of the outer surface of the T-shaped sliding gear plate 23 slides in the U-shaped guide clamping plate 25, the rightward movement of the T-shaped sliding gear plate 23 will drive the meshing gear shaft 24 to start rotating counterclockwise on the outer surface of the connecting fixed shaft 14. At the same time, because the bottom end of the meshing gear shaft 24 is fixedly connected to the multifunctional extrusion cylinder 26, and the inner wall of the multifunctional extrusion cylinder 26 is connected to the connecting fixed shaft 14, the counterclockwise rotation of the U-shaped guide clamping plate 25 will drive the multifunctional extrusion cylinder 26 to start rotating counterclockwise. Figure 6As shown, because the extrusion column 29 is slidably connected in the extrusion groove 28 starting from the outer surface of the multifunctional extrusion cylinder 26, and the extrusion column 29 is fixedly connected to the upper surface of the pressing exhaust disk 27, and the outer periphery of the pressing exhaust disk 27 is slidably connected to the inner wall of the preheating mixing chamber 11, when the multifunctional extrusion cylinder 26 rotates counterclockwise, the extrusion groove 28 rotates counterclockwise to squeeze the extrusion column 29, so the pressing exhaust disk 27 starts to move downward through the extrusion effect of the extrusion column 29 and the extrusion groove 28. Since the pressing exhaust disk 27 slides on the inner wall of the preheating mixing chamber 11 and has good sealing performance, the vineyard in the preheating mixing chamber 11 and located on the lower surface of the pressing exhaust disk 27 will begin to be compressed when the pressing exhaust disk 27 is in the downward process. At the same time, by pressing the exhaust disk 27 to slide back and forth on the inner wall of the preheating stirring chamber 11, the air pressure in the preheating stirring chamber 11 is constantly changed. At this time, the bubbles escaping from the original slurry will burst under the action of the air pressure. Since the orifice provides an escape path for the bubbles, the accumulation of bubbles during the stirring process is reduced. The existing methods for removing bubbles include standing, centrifugal separation, etc., but these methods often require additional equipment or time to achieve bubble removal. By pressing the exhaust disk 27 to slide back and forth on the inner wall of the preheating stirring chamber 11, not only can the pressure in the stirring barrel be directly changed during the stirring process, but the bubbles can be quickly burst and released under the pressure change, thereby achieving efficient elimination of bubbles. This method not only simplifies the process flow, but also greatly improves the efficiency of bubble removal.

[0073] Moreover, by pressing the exhaust disk 27 to slide back and forth on the inner wall of the preheating mixing chamber 11, not only the pressure in the mixing barrel is changed, but also the flow and mixing of the grape puree are promoted. This dynamic mixing method is not only conducive to breaking up the lumps and clumps in the raw materials, making the grape puree more uniform and delicate, but also the change in pressure helps to enhance the mixing effect, so that the ingredients in the raw materials are better integrated and the overall quality of the product is improved.

[0074] At the same time Figure 7As shown, when the multifunctional extrusion cylinder 26 rotates counterclockwise, because the upper end of the connecting cylinder 31 is fixedly connected to the bottom of the multifunctional extrusion cylinder 26, and the inner wall of the connecting cylinder 31 is sleeved on the outer surface of the connecting fixed shaft 14, the counterclockwise rotation of the multifunctional extrusion cylinder 26 will drive the connecting cylinder 31 to start rotating in the same direction. At this time, because the scraper 32 symmetrically fixedly connected to the outer surface of the connecting cylinder 31 fits with the inner wall of the preheating mixing chamber 11, when the connecting cylinder 31 rotates counterclockwise, the scraper 32 will start to move in the preheating mixing chamber 11. When rotating counterclockwise, the scraper 32 and the inner wall of the preheating stirring chamber 11 are in contact with each other and rotated, so that the sticky puree on the inner wall of the preheating stirring chamber 11 can be evenly scraped off, so as to prevent the inner wall from sticking during preheating, resulting in uneven preheating effect of grape puree, and further making it difficult to accurately control the preheating time. At this time, the first beveled teeth 33 and the beveled teeth 34 fixedly connected at the lower end of the scraper 32 are meshed with each other. Because the beveled teeth 34 are symmetrically assembled on both sides of the tooth surface of the connecting tube 31 and have the same working principle, only the first beveled teeth 33 and the beveled teeth 34 are meshed with each other. Figure 7 Describe as shown;

[0075] At this time, the counterclockwise rotation of the connecting tube 31 will drive the bevel gear 34 to start rotating in the clockwise direction. At the same time, because the bevel gear 34 is fixedly connected with the bubble removal stirring shaft 35, and the bubble removal stirring shaft 35 is composed of a triangular plate and a flow partition, and the flow partition is evenly provided with bubble holes, when the bubble removal stirring shaft 35 is driven by the bevel gear 34 to start rotating counterclockwise, the bubble removal stirring shaft 35 can be made to stir the original slurry in the clockwise direction. At this time, because the tooth surface of the second bevel gear 36 is meshed with the tooth surface of the bevel gear 34, and because the multifunctional stirring and cleaning shaft 37 is fixedly connected to the bottom end of the non-tooth surface of the second bevel gear 36, the bubble removal stirring shaft 35 is rotated in the clockwise direction through the bevel gear 34. The clockwise rotation will drive the multifunctional stirring and cleaning shaft 37 to rotate clockwise in the preheating stirring chamber 11. At this time, because the stirring blades of the multifunctional stirring and cleaning shaft 37 are respectively in contact with the bottom of the preheating stirring chamber 11 and the inner wall of the preheating stirring chamber 11, and bubble holes are evenly opened in the stirring blades, during the stirring process, the gas inside the liquid is dispersed into small bubbles by the stirring shear force, and these small bubbles will try to rise to the liquid surface and escape during the stirring process. The bubble holes on the stirring blades provide an additional escape path for these bubbles, so that the bubbles can be more easily discharged from the stirring area, thereby reducing the accumulation of bubbles during the stirring process;

[0076] At the same time, by pressing the exhaust disk 27 to slide back and forth on the inner wall of the preheating stirring chamber 11, the air pressure in the preheating stirring chamber 11 is constantly changed. At this time, the bubbles escaping from the puree will burst under the action of the air pressure. Since the orifices provide an escape path for the bubbles, the accumulation of bubbles during the stirring process is reduced, thereby improving the stirring efficiency. The reduction of bubbles means that the stirring medium can flow and mix more smoothly, reducing the uneven stirring caused by bubble obstruction. When the grape puree is evenly stirred, the heat distribution inside it will be more uniform, which means that during the heat treatment process, the heat can be transferred to various parts of the puree more quickly, thereby reducing the time required for the whole to reach the required sterilization temperature. At the same time, preventing the puree from sticking to the inner wall also helps to keep the heating container clean and the heat transfer efficiency, because the sticky inner wall may form an insulating layer that hinders heat transfer.

[0077] Please refer to the above working process Figures 1 to 7 .

[0078] The following is the working process of the height-adjustable protection mechanism 4 for preventing the preheating and stirring bin 11 from being deformed and damaged due to low air pressure in the preheating and stirring bin 11:

[0079] When in use, when the operator manually rotates the adjustment wheel 41 clockwise as needed, Figure 5As shown, because the threaded shaft 42 is fixedly connected to the bottom of the adjusting wheel 41, and the outer surface of the threaded shaft 42 is threadedly connected to the surface of the preheating stirring bin 11, and the lower end of the threaded shaft 42 is rotatably connected to the connecting and fixing shaft 14, because the supporting slide plate 13 slides on the inner wall of the preheating stirring bin 11 as a whole, the clockwise rotation of the adjusting wheel 41 will drive the upper threaded shaft 42 to rotate clockwise. At this time, the clockwise rotation of the threaded shaft 42 will drive the connecting and fixing shaft 14 to start pulling the supporting slide plate 13 to slide upward on the inner wall of the preheating stirring bin 11, and because the reciprocating pressing mechanism 2 and the multifunctional stirring and cleaning mechanism 3 are both arranged in the connecting and fixing shaft 14, the overall upward movement of the connecting and fixing shaft 14 will cause the stirring reciprocating pressing mechanism 2 and the multifunctional stirring and cleaning mechanism 3 to move up and down as a whole, and by adjusting the connecting and fixing The position of the shaft 14 can be determined according to the characteristics of the grape puree and the shape of the mixing barrel. For example, when the stirring shaft is placed as a whole at a lower position inside the grape puree in the mixing barrel, the stirring shaft can generate a stronger shear force through stirring, which is beneficial to cutting large bubbles in the grape puree into small bubbles and quickly releasing them; when the stirring shaft is placed at a higher position in the grape puree stirring part of the mixing barrel, the vortex generated by the stirring can be used to bring the bubbles to the surface of the liquid and discharge them. By changing the stirring at different positions, a more uniform stirring effect can be achieved, the preheating efficiency can be improved, and the preheating time can be shortened. Compared with the prior art, compared with the stirring shaft with a fixed position, the connected fixed shaft 14 with an adjustable position has higher flexibility. It can be flexibly adjusted according to different production requirements and process conditions to achieve the best stirring effect and preheating efficiency.

[0080] Further Figure 6 As shown, because the push exhaust disk 27 is symmetrically provided with arc exhaust holes, a bevel plug 43 is slidably connected to the arc exhaust hole on the lower surface of the push exhaust disk 27, a compression spring 44 is fixedly connected to the upper surface of the bevel plug 43, and an exhaust hood 45 is fixedly connected to the end of the compression spring 44 away from the bevel plug 43, and the bottom of the exhaust hood 45 is fixedly connected to the upper surface of the push exhaust disk 27. Therefore, at this time, when the preheating stirring chamber 11 is located at the lower surface of the push exhaust disk 27 due to gas compression, the inner wall of the preheating stirring chamber 11 will be affected by the suction generated by the internal high pressure. If this suction becomes too large, It will act on the bevel plug 43, and start to slide downward along the arc exhaust hole by pushing the bevel plug 43. At this time, the compression spring 44 is stretched, and the gas at the bottom of the pressing exhaust disk 27 in the preheating stirring chamber 11 will flow out along the arc exhaust hole to the exhaust hood 45, and be discharged to the upper surface of the pressing exhaust disk 27 through the exhaust hood 45. Since the connecting fixed shaft 14 and the upper end of the preheating stirring chamber 11 are both provided with exhaust holes, the gas will be discharged along the connecting fixed shaft 14 and the exhaust hole of the preheating stirring chamber 11, thereby preventing the preheating stirring chamber 11 from being deformed and damaged due to too low air pressure.
