Description

Technical Field

[0001] This utility model belongs to the field of fermentation equipment technology, and specifically relates to a raw material fermentation device with a built-in temperature control structure. Background Technology

[0002] Existing raw material fermentation devices generally employ external temperature control structures, a design that makes precise temperature control of the materials inside the pipes difficult. Because the temperature control device is installed outside the pipeline, heat transfer must occur between the pipe wall and the material, resulting in significant heat transfer lag and unevenness, especially noticeable in large-diameter or long-distance pipelines. This temperature control method easily leads to localized overheating or large temperature fluctuations in the material, affecting the stability of the fermentation process and even triggering side reactions, reducing product yield and quality.

[0003] Conventional solutions mainly include increasing the number of temperature measurement points to improve monitoring frequency, optimizing the insulation layer design to reduce external environmental interference, or adjusting the flow rate to improve temperature distribution. However, these measures cannot fundamentally solve the problem of low temperature control accuracy: increasing the number of temperature measurement points can improve the feedback speed, but it also increases system complexity and maintenance costs; optimizing the insulation layer can only alleviate, not eliminate, the temperature gradient; and adjusting the flow rate is limited by process parameter requirements and may adversely affect the overall process. Therefore, we hope to design a raw material fermentation device with a novel structure to solve this problem. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] As the first embodiment of this utility model:

[0024] Please see Figures 1 to 3A raw material fermentation device with built-in temperature control structure includes: a tank 100, a sealing cover movably installed on the upper side of the tank 100, a temperature control component 200 for temperature control of fermentation materials installed inside the tank 100, a drive motor 110 installed at the bottom of the tank 100, and a stirring component 120 rotatably installed inside the tank 100.

[0025] The temperature control component 200 includes a first delivery pipe 210, the right end of which is fixedly connected to the lower right side of the second delivery pipe 220, the left rear side of the second delivery pipe 220 is connected to the third delivery pipe 240 through a first connecting pipe 230, and the left side of the third delivery pipe 240 is connected to the left end of the fourth delivery pipe 260 through a second connecting pipe 250.

[0026] A large gear 130 is rotatably mounted at the bottom of the tank body 100. The large gear 130 is fixedly connected to the lower end of the stirring component 120. The drive motor 110 is connected to the reducer shaft and is connected to the large gear 130 through a small gear.

[0027] The stirring component 120 includes a rotating shaft 121, on which a plurality of stirring blades 122 for stirring are fixed. The top end of the rotating shaft 121 is rotatably connected to a fixed plate 123 via a bearing. The fixed plate 123 is placed on the upper end of the tank 100 and fixedly connected.

[0028] Specifically, by setting a stirring element 120 inside the tank 100 and a hollow rotating shaft 121, which is matched with the conveying pipe 210 in the temperature control component 200, in actual use, after the external refrigerant enters the conveying pipe 210, it is conveyed to the hollow rotating shaft 121 through the rotary joint. This avoids the surrounding material from heating up after the rotating shaft 121 rotates, thus reducing the heat radiation of the rotating shaft 121. At the same time, it can slowly rotate to stir the material in the tank 100, avoiding local heat accumulation in the material.

[0029] As a second embodiment of this utility model:

[0030] Please see Figures 1 to 3 The left end of the conveying pipe 210 is fixedly connected to the lower end of the rotating shaft 121 via a rotary joint. The rotating shaft 121 has a hollow interior. The conveying pipe 210 is connected to an external refrigerant supply device. A switch valve is installed on the right end of the conveying pipe 210. In actual use, refrigerant can be delivered to the interior of the rotating shaft 121 by opening the switch valve, thereby cooling the rotating shaft 121. A discharge pipe is provided on the rotary joint to realize the entry and discharge of refrigerant. The rotary joint can be selected from existing products on the market as needed to meet the requirements of refrigerant entry and discharge.

[0031] A second switch valve is installed on the right side of the second conveying pipe 220. The left side of the second conveying pipe 220 extends into the tank 100 and is equipped with a cooling ring pipe 1. The cooling ring pipe 1 is fitted on the outside of the rotating shaft 121, and its axis is collinear with the axis of the rotating shaft 121.

[0032] A connecting pipe 230 is provided on the rear side of the cooling ring pipe 1. The connecting pipe 230 has a horizontal U-shaped structure. The left side of the conveying pipe 240 extends into the tank 100 and is provided with a cooling ring pipe 2. The cooling ring pipe 2 is located directly above the cooling ring pipe 1 and its rear side is fixedly connected to the upper end of the connecting pipe 230.

[0033] The left side of the fourth conveying pipe 260 extends into the tank 100 and is equipped with a third cooling ring pipe. The third cooling ring pipe is located directly above the second cooling ring pipe. The left side of the second cooling pipe is connected to the left side of the third cooling ring pipe through a horizontally placed U-shaped connecting pipe 250. The first connecting pipe 230 and the second connecting pipe 250 do not contact the rotating stirring blade 122. In actual use, the temperature control component 200 delivers refrigerant to the inside of the tank 100 through the second conveying pipe 220, the third conveying pipe 240 and the fourth conveying pipe 260, thereby enabling direct temperature control of the fermentation material inside the tank 100, which helps to improve the efficiency and effect of temperature control.

[0034] A switch valve is installed on the right side of the three-way conveying pipe 240, and a switch valve is installed on the right side of the four-way conveying pipe 260. The right side of the switch valve is connected to the switch valve 3 through a discharge pipe.

[0035] Based on the first embodiment described above, further, in actual use, when the second switch valve is opened, external refrigerant enters the first cooling ring pipe above it through the second conveying pipe 220 to cool the material at the bottom of the tank 100. Subsequently, the refrigerant in the first cooling ring pipe is transported through the first connecting pipe 230 to the second cooling ring pipe on the third conveying pipe 240 to cool and control the temperature of the material in the middle of the tank 100. At this time, when the switch valve on the second conveying pipe 220 is closed, the refrigerant is transported through the second connecting pipe 250 to the third cooling ring pipe of the fourth conveying pipe, and finally through the right side of the fourth conveying pipe... Side discharge: If valve three is open, no refrigerant passes through pipeline four. This should be used when the material height inside tank 100 is lower than pipeline four 260. Temperature control component 200 can deliver external refrigerant to the inside of tank 100 through pipeline two 220, pipeline three 240 and pipeline four 260, so that it can directly contact the material, thereby effectively and quickly controlling and cooling the material. This effectively solves the problem that optimizing the insulation layer can only alleviate but not eliminate the temperature gradient, and adjusting the flow rate is limited by process parameter requirements, which may have an adverse effect on the overall process.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
