Abstract
Description
Technical Field
[0001] This utility model relates to the field of vinegar brewing equipment technology, and in particular to a cooking pot for vinegar brewing. Background Technology
[0002] Vinegar is not only an indispensable condiment in cooking, but its unique flavor and nutritional components are also loved by consumers. In the vinegar brewing process, the steaming and cooking stage is a crucial step. Traditional steaming pots used in vinegar production have significant shortcomings in terms of the uniformity of material heating. Early steaming pots often used simple bottom heating methods, such as setting up a heater at the bottom or introducing steam, with heat conducted upwards from the bottom. Due to this single heat transfer method, the heat conduction speed in the material is slow, resulting in uneven heating between the upper and lower layers. With continuous social development, in order to improve this situation, some steaming pots... The jacketed heating method involves setting up a jacket on the outside of the pot and introducing steam for heating. However, this method also has its drawbacks. During the heating process, the heat is mainly conducted to the material through the pot wall. The heat transfer efficiency varies at different locations on the pot wall. The pot wall temperature is higher near the steam inlet, and the material is heated faster. However, the pot wall temperature is relatively lower further away from the steam inlet, and the material is heated more slowly. This results in uneven heating of the material in the circumferential direction. Although a stirring device is currently installed inside the pot for mixing, there are still dead zones in the stirring, which leads to uneven heating.
[0003] Based on the above situation, it is necessary to design a cooking pot for vinegar production to solve the above problems. Utility Model Content
[0004] This invention provides a cooking pot for vinegar production to solve the problems existing in the prior art.
[0005] The technical problem solved by this utility model is achieved by the following technical solution:
[0006] A cooking pot for vinegar production includes a cooking pot body and an agitator. The cooking pot body includes a pot body and a pot lid. The pot lid is installed on the upper end of the pot body via a telescopic component, and an inner jacket for introducing heating steam is provided on the outer periphery of the pot body. The agitator is rotatably connected to the pot lid, and the pot lid is provided with a drive mechanism for driving the agitator to rotate. The agitator includes a hollow stirring shaft and a hollow stirring paddle connected to the hollow stirring shaft. One end of the hollow stirring shaft is connected to the steam output end of the inner jacket via a connecting hose, for introducing the steam discharged from the inner jacket into the hollow stirring shaft. The hollow stirring paddle and the hollow stirring shaft form a closed steam channel, for conducting the heat of the steam in the agitator to the material in the pot body through its wall surface, so as to achieve uniform heating.
[0007] Preferably, an outer jacket is provided on the outside of the inner jacket, and the output end of the inner jacket and the input end of the outer jacket are connected by a conveying pipe, and a first pressure relief pipe is connected to the outer jacket.
[0008] Preferably, a heat-insulating space is formed between the inner jacket and the outer jacket.
[0009] Preferably, a water collection box is detachably connected to the bottom end of the hollow stirring shaft, and a second pressure relief pipe is provided at the upper end of the hollow stirring shaft.
[0010] Preferably, the hollow stirring paddles are in multiple sets, and the multiple sets of hollow stirring paddles are equidistant from the circumference of the hollow stirring shaft, and each set of hollow stirring paddles is inclined downward toward the hollow stirring shaft.
[0011] Preferably, the driving mechanism includes a drive motor and a drive gear connected to the output end of the drive motor, and the hollow stirring shaft is provided with a driven gear that meshes with the drive gear.
[0012] Preferably, both the inner and outer jackets are connected to a drainage pipe at their lowest points.
[0013] The beneficial effects of this utility model are:
[0014] 1. Part of the heated steam enters the sealed steam channel of the hollow stirring shaft and stirring paddle. The heat of the steam is conducted to the material in the cooking pot through the wall of the stirring component. Combined with the driving mechanism to tumble the stirring component, the contact area between the material and the heating surface can be increased. It can also heat the material near the center of the pot body, reduce the dead zone of heating, and avoid local overheating or undercooking during cooking.
[0015] 2. By setting up an outer jacket, excess steam heat from the inner jacket is discharged into the outer jacket, forming insulation on the outside of the inner jacket, thereby reducing heat loss from the inner jacket. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0024] Reference Figures 1-5 As shown, a cooking pot for vinegar production includes a cooking pot body, which comprises a pot body 1 and a pot lid 2. The cooking pot can be installed via a mounting bracket, on which a telescopic component 3 is provided. The telescopic component 3 can be a hydraulic telescopic component, etc., which opens from the pot body 1 to allow material to be fed in and removed. An inner jacket 4 for introducing heating steam is provided on the outer periphery of the pot body 1. The inner jacket 4 can be connected to a pipe that connects to an external steam output device to input high-temperature steam into the inner jacket 4 to heat the pot body 1. The pot lid 2... The upper part is rotatably connected to the agitator 5, and the pot cover 2 is provided with a drive mechanism for driving the agitator 5 to rotate. The agitator 5 includes a hollow stirring shaft 51 and a hollow stirring paddle 52 connected to the hollow stirring shaft 51. One end of the hollow stirring shaft 51 is connected to the steam output end of the inner jacket 4 through a connecting hose 6, which is used to introduce the steam discharged from the inner jacket 4 into the hollow stirring shaft 51. The hollow stirring paddle 52 and the hollow stirring shaft 51 form a closed steam channel, which is used to conduct the heat of the steam in the agitator 5 to the material in the pot body 1 through its wall surface, so as to achieve uniform heating.
[0025] Specifically, the high-temperature steam inside the inner jacket 4 enters the hollow stirring shaft 51 through the connecting hose 6. The connecting hose 6 and the hollow stirring shaft 51 are sealed together by a rotary joint 61. The rotary joint 61 mainly consists of a fixed end (shell) and a rotating end (spindle). The fixed end is connected to the connecting hose 6 and does not rotate with the hollow stirring shaft 51. The rotating end is coaxially connected to the hollow stirring shaft 51 and rotates synchronously with the shaft. It is in contact with the smooth end face of the rotating ring that rotates with the rotating end and the stationary ring fixed in the shell, and there is a radial distance between the rotating end and the fixed end. An elastic rubber O-ring is installed in the gap, and the medium pressure or pre-tightening force is used to squeeze and seal it to prevent steam leakage. The above is the existing technology and will not be elaborated here. When the steam in the inner jacket 4 enters the hollow stirring shaft 51 and the hollow stirring paddle 52, when it cooperates with the drive mechanism, it can heat the material near the center of the pot body 1 while stirring the material, reducing the heating dead zone and avoiding local overheating or undercooking during cooking. The connecting hose 6 can be spiral-shaped, so that when the telescopic part 3 drives the pot lid 2 to move upward, it will not affect the extension of the connecting hose 6.
[0026] Reference Figure 3 As shown, further, an outer jacket 7 is provided on the outside of the inner jacket 4, and the output end of the inner jacket 4 and the input end of the outer jacket 7 are connected by a conveying pipe 71. A first pressure relief pipe 72 is connected to the outer jacket 7. Some of the hot steam inside the inner jacket 4 enters the outer jacket 7 through the conveying pipe 71, forming a heat wrap on the outside of the inner jacket 4, recovering and reusing the residual heat inside the inner jacket 4, while reducing the heat loss of the inner jacket 4 and improving the cooking effect of the pot 1. Both the inner jacket 4 and the outer jacket 7 can be made of metal to achieve better heat conduction performance. In order to avoid burns to personnel caused by the outer jacket 7, a heat insulation material such as rock wool can also be installed on the outside of the outer jacket 7. Some of the steam inside the outer jacket 7 can be discharged through the first pressure relief pipe 72.
[0027] If the inner jacket 4 and the outer jacket 7 are directly connected, the heat of the inner jacket 4 will be quickly conducted to the outer wall of the outer jacket 7 and then dissipated to the environment, which is equivalent to a "thermal short circuit". Therefore, a heat insulation space 73 is formed between the inner jacket 4 and the outer jacket 7. Since air is a poor conductor of heat, the heat in the inner jacket 4 will not be directly transferred to the outer jacket 7, so that the heat can only be transferred through slow thermal radiation and weak convection, rather than rapid metal heat conduction, thus reducing the heat loss effect.
[0028] Reference Figure 5As shown, a water collection box 54 is detachably connected to the bottom end of the hollow stirring shaft 51. The condensate inside the hollow stirring shaft 51 can be collected in the water collection box 54. Then, when the telescopic component 3 moves the pot lid 2 and the stirring component 5 out of the pot body 1, the water collection box 54 can be removed and poured out to prevent the condensate from being directly discharged into the pot body 1 and coming into contact with the material during cooking. At the same time, a second pressure relief pipe 53 is provided at the upper end of the hollow stirring shaft 51. Some of the steam entering the stirring component 5 can be discharged through the second pressure relief pipe 53 to avoid the stirring component 5 from deforming or cracking due to overpressure and other safety hazards.
[0029] Reference Figure 4 As shown, there are multiple sets of hollow stirring paddles 52. The multiple sets of hollow stirring paddles 52 are equidistant from the circumference of the hollow stirring shaft 51, and each set of hollow stirring paddles 52 is inclined downward towards the hollow stirring shaft 51. The condensate in the hollow stirring paddles 52 can flow into the hollow stirring shaft 51 under the action of gravity and can be collected in the water collection box 54.
[0030] Reference Figure 1 As shown, the drive mechanism further includes a drive motor 8 and a drive gear 81 connected to the output end of the drive motor 8. The hollow stirring shaft 51 is provided with a driven gear 82 that meshes with the drive gear 81. The drive motor 8 drives the drive gear 81 and the driven gear 82 to rotate, thereby realizing the circumferential rotation of the stirring component 5. While stirring the material in the pot, it can also increase the full contact between the material and the heat.
[0031] Reference Figures 1-5 As shown, furthermore, the lowest ends of both the inner jacket 4 and the outer jacket 7 are connected to a drain pipe 9, and a drain valve can be correspondingly installed on the drain pipe 9 to facilitate the discharge of condensate in the inner jacket 4 and the outer jacket 7.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
