DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the following embodiments are combined with the attached Figure 1 To Attachment Figure 3 The technical solution provided by the utility model is described in detail, but the following content is not intended to limit the utility model.

[0024] Figure 1 This is a structural diagram from one perspective of an embodiment of a high-pressure fermentation barrel with a temperature control structure of the utility model; Figure 2 This is a structural diagram of another perspective of an embodiment of a high-pressure fermentation barrel with a temperature control structure of the utility model. Figure 1 and Figure 2 As shown, the high-pressure fermentation barrel with a temperature control structure provided in this embodiment includes: a fermentation barrel body 1 and a temperature sensor. In addition, in order to ensure that the fermentation barrel can meet the high-pressure use requirements, the fermentation barrel body 1 can be used in conjunction with a barrel cover. At this time, the barrel cover is buckled on the barrel mouth of the fermentation barrel body 1. When high-pressure fermentation is required, the barrel cover can be installed on the barrel mouth of the fermentation barrel body 1, and when high-pressure fermentation is not required, the barrel cover can be removed from the barrel mouth of the fermentation barrel body 1, which has better adaptability.

[0025] Figure 3 1 is a cross-sectional view of an embodiment of a high-pressure fermentation barrel with a temperature control structure of the utility model. Figures 1 to 3 As shown, the fermentation barrel body 1 includes an inner barrel 11 and an outer barrel 12. At this time, the outer barrel 12 is sleeved on the lower part of the inner barrel 11, that is, a double-layer structure is formed at the bottom of the fermentation barrel body 1 through the cooperation of the outer barrel 12 and the inner barrel 11. A gap is provided between the inner wall of the outer barrel 12 and the outer wall of the inner barrel 11 to form a temperature control chamber 13, which provides conditions for the subsequent temperature medium including water to enter the temperature control chamber 13 to adjust the fermentation temperature of the fermentation barrel body 1. At the same time, two connecting flanges 2 are symmetrically arranged on the outer side wall of the fermentation barrel body 1. At this time, the two connecting flanges 2 are arranged in the direction of the central axis of the fermentation barrel body 1 vertically, so that the two connecting flanges 2 can stably support the fermentation barrel body 1, avoiding the problem of the fermentation barrel body 1 tilting. At the same time, the fermentation barrel body 1 can also be supported by the two connecting flanges 2 to achieve the installation of the fermentation barrel body 1. Furthermore, the two connecting flanges 2 are rotatably mounted on the external bracket, that is, the fermentation barrel body 1 is mounted on the external bracket through the connecting flanges 2, and the fermentation barrel body 1 can be deflected relative to the external bracket, which provides conditions for pouring the fermented material in the fermentation barrel body 1 from the barrel mouth after the fermentation barrel body 1 is deflected, and for cleaning the fermentation barrel body 1, and the operation is more convenient. In addition, an inlet 3, an outlet 4 and a temperature measuring hole 5 connected to the temperature control chamber 13 are also provided at the bottom of the fermentation barrel body 1, so that the temperature medium including water can enter the temperature control chamber 13 from the inlet 3, and the temperature medium in the temperature control chamber 13 can be discharged from the outlet 4, which provides conditions for realizing the fermentation temperature regulation of the fermentation barrel body 1, and can meet the use requirements of adjusting the fermentation temperature in the fermentation barrel body 1 by changing the temperature medium in the temperature control chamber 13 during the fermentation process, and realize real-time temperature regulation. In addition, a drain pipe 14 connected to the inner barrel 11 is provided at the bottom of the side wall of the fermentation barrel body 1, so that the liquid substance in the fermentation barrel body 1 can be discharged through the drain pipe 14 at the bottom thereof. At this time, the discharge of the liquid fermentation substance in the fermentation barrel body 1 can be satisfied without the need to deflect the fermentation barrel body 1 as a whole, and the structural design is more reasonable. In addition, a temperature measuring structure is installed through the temperature measuring hole 5, and the fermentation temperature is monitored in real time through the temperature measuring structure to ensure that the fermentation temperature meets the processing requirements.

[0026] Specifically, a temperature sensor is selected as the temperature measuring structure. At this time, the temperature sensor is set at the temperature measuring hole 5 at the bottom of the fermentation barrel body 1, and when the temperature sensor is installed in place, the temperature measuring head of the temperature sensor extends from the temperature measuring hole 5 into the temperature control cavity 13. At the same time, the temperature measuring head of the temperature sensor contacts the bottom of the inner barrel 11, that is, the fermentation temperature is monitored in real time through the temperature sensor, which provides a reference condition for adjusting the fermentation temperature.

[0027] More specifically, the drain pipe 14 is tilted downward away from the end connected to the inner barrel 11, so that the drain pipe 14 is in a state where one end is high and the other end is low. At this time, the lowest point of the tube hole of the end of the drain pipe 14 connected to the inner barrel 11 is set to be flush with the bottom of the inner barrel 11, ensuring that the lowest point of the highest end of the tube hole of the drain pipe 14 can be flush with the bottom of the inner barrel 11, so that the fermented material at the bottom of the inner barrel 11 can also be completely discharged through the drain pipe 14, avoiding the problem of residue.

[0028] More specifically, a guide plate 6 is further provided at the barrel mouth of the fermentation barrel body 1. At this time, both sides of the guide plate 6 at one end away from the fermentation barrel body 1 are bent to form side baffles 61, that is, both sides of one end of the guide plate 6 have side baffles 61, and the baffles 61 on both sides are used to guide the subsequent pouring of the fermented material. At this time, the interval between the baffles 61 on both sides is set as the pouring port 62, and the distance between the baffles 61 on both sides at the pouring port 62 is the smallest, so that the baffles 61 on both sides are relatively inclined, so that the fermented material can gather at the pouring port 62 when it reaches the barrel mouth of the fermentation barrel body 1, thereby avoiding the splashing and diffusion of the fermented material during the pouring process, and facilitating the pouring and collection.

[0029] More specifically, a mouth hoop 7 is further provided on the outer edge of the barrel mouth of the fermentation barrel body 1. At this time, the mouth hoop 7 is arranged in a ring shape. Since the outer barrel 12 of the fermentation barrel body 1 is sleeved on the lower part of the inner barrel 11, the upper barrel mouth of the inner barrel 11 is the barrel mouth of the fermentation barrel body 1, that is, the mouth hoop 7 is fixedly installed on the outer edge of the barrel mouth of the inner barrel 11. The mouth hoop 7 effectively strengthens the structural strength of the barrel mouth of the fermentation barrel body 1 to prevent deformation when the fermented material is poured. In addition, a protruding structure can be formed at the barrel mouth of the fermentation barrel body 1, which provides conditions for a snap-on connection with the barrel cover if a barrel cover is used later.

[0030] More specifically, the mouth of the outer barrel 12 is bent toward the inner side of the barrel to form the sealing edge 121, which ensures the structural strength of the sealing edge 121 and the outer barrel 12. At the same time, the width of the sealing edge 121 can be used as the width of the interval for forming the temperature control chamber 13, ensuring that a stable temperature control chamber 13 can be formed between the outer barrel 12 and the inner barrel 11 after the outer barrel 12 and the inner barrel 11 are assembled. In addition, when the outer barrel 12 is sleeved outside the inner barrel 11, the sealing edge 121 abuts against the outer wall of the inner barrel 11 and is welded, so that the outer barrel 12 and the inner barrel 11 are connected and fixed by the sealing edge 121, and the structural design is more reasonable.

[0031] More specifically, a plurality of support columns 8 are further provided in the temperature control chamber 13, and the plurality of support columns 8 are arranged at intervals in the temperature control chamber 13, so that there are intervals between adjacent support columns 8, which facilitates the flow of the temperature medium in the temperature control chamber 13. In addition, the two ends of the support column 8 are respectively abutted against the outer wall of the inner barrel 11 and the inner wall of the outer barrel 12, that is, the inner barrel 11 is supported in the outer barrel 12 by the support column 8, so that the support column 8 plays a major supporting role, avoiding the problem that the temperature medium cannot flow due to the fit between the outer wall of the inner barrel 11 and the inner wall of the outer barrel 12, and also realizing the support of the outer barrel 12 to the inner barrel, thereby improving the bearing capacity of the inner barrel.

[0032] Preferably, a plug is provided on the upper end face of the support column 8, and the cross-section of the plug is smaller than the cross-section of the support column 8, so that a step is formed between the plug and the support column 8, and a plurality of insertion holes are provided on the bottom of the inner barrel 11. During installation, the lower end of the support column 8 is welded to the bottom of the outer barrel 12, and the plug at the upper end of the support column 8 is inserted into the corresponding insertion hole on the inner barrel 11, and the step formed between the plug and the support column 8 rests on the bottom of the barrel outside the inner barrel 11, which can facilitate the installation of the support column 8 on the outer barrel 12 and the inner barrel 11, and at the same time, enable the support column 8 to better support the inner barrel 11, so that the bearing capacity of the inner barrel 11 is stronger and the shape of the temperature control cavity 13 is more stable.

[0033] More specifically, the inner barrel 11 and the outer barrel 12 are both made of stainless steel. At the same time, the inner barrel 11 and the outer barrel 12 are connected by welding, which not only has stable chemical properties but also ensures structural strength, thereby extending the service life of the fermentation barrel body 1.

[0034] More specifically, each connecting flange 2 arranged on the fermentation barrel body 1 includes a connecting seat 21 and a flange plate 22. At this time, the connecting seat 21 is arranged in a "U" shape so that the middle part of the connecting seat 21 can be arched, which provides conditions for the flange plate 22 to avoid the outer wall of the fermentation barrel body 1 and facilitate the installation of the flange plate 22 on the external bracket and the connection with the rotary drive. In addition, the two ends of the connection seat 21 are respectively fixedly connected to the outer wall of the fermentation barrel body 1, so that the connection seat 21 is installed on the outer wall of the fermentation barrel body 1, and the middle part of the connection seat 21 protrudes outside the outer wall of the fermentation barrel body 1 along the radial direction of the fermentation barrel body 1. At the same time, the flange 22 is fixedly installed in the middle part of the connection seat 21, so that when the flange 22 is installed on the fermentation barrel body 1 through the connection seat 21, the flange 22 can be in the radial direction of the fermentation barrel body 1. At the same time, a gap is set between the flange 22 and the outer wall of the fermentation barrel body 1, so that after the subsequent installation through the connection flange 2, the outer wall of the fermentation barrel body 1 will not be interfered by the external structure, thereby ensuring that the fermentation barrel body 1 can be smoothly deflected. In addition, a plurality of installation holes 221 are set on the flange 22. When installing, the flange 22 can be connected to other matching structures by bolts, etc., which is more convenient for disassembly and assembly. Preferably, a rotating shaft is rotatably mounted on the external bracket via a bearing. At this time, one end of the rotating shaft is dynamically connected to the driving shaft of the rotating driver, and a matching flange is provided at the other end of the rotating shaft, which is connected to the flange plate 22 of the connecting flange 2 through the matching flange, so that the rotating driver can drive the fermentation barrel body 1 to flip on the external bracket.

[0035] More specifically, a safety tube 9 is further provided on the outer wall of the outer barrel 12. At this time, one end of the safety tube 9 is connected to the temperature control chamber 13, so that after the temperature medium enters the temperature control chamber 13, if the temperature of the temperature control chamber 13 is accidentally increased and the pressure thereof is increased, it can be quickly discharged through the safety tube 9 to improve safety. Preferably, a pressure relief valve is installed on the safety tube 9, which can automatically release the pressure when the pressure in the temperature control chamber 13 increases to a predetermined value, and the safety guarantee is higher.

[0036] The high-pressure fermentation barrel with a temperature control structure provided in this embodiment includes a fermentation barrel body 1 and a temperature sensor. The fermentation barrel body 1 including an inner barrel 11 and an outer barrel 12 is provided, and a temperature control chamber 13 is formed at the lower part of the inner barrel 11 through the outer barrel 12, and an inlet 3, an outlet 4 and a temperature measuring hole 5 connected to the temperature control chamber 13 are provided, so that the temperature medium can regulate the fermentation temperature of the inner barrel 11 in the temperature control chamber 13 through the inlet 3 and the outlet 4, so as to meet the use requirement of adjusting the fermentation temperature during the fermentation process. At the same time, a temperature measuring sensor is provided at the temperature measuring hole 5 to monitor the fermentation temperature in real time to ensure that the fermentation temperature meets the processing requirements. In addition, connecting flanges 2 are symmetrically provided on both sides of the fermentation barrel body 1. The fermentation barrel body 1 is rotatably installed on the external bracket through the connecting flanges 2 and is connected to the rotary drive power, so that the fermentation barrel body 1 can be turned over, which is convenient for pouring out the fermented material in the fermentation barrel body 1, and also convenient for subsequent cleaning of the fermentation barrel body 1, which is more convenient to use.
