Description

Technical Field

[0001] The utility model belongs to the field, in particular to an industrial enzyme preparation device. Background Art

[0002] The preparation of industrial enzymes is usually carried out in fermenters, which are usually large stainless steel vessels equipped with agitators, temperature and pH controllers, and dissolved oxygen sensors, etc.

[0003] During the fermentation or reaction process, the generation of foam may cause the liquid to overflow from the container, which not only wastes raw materials but also pollutes the environment. In addition, the generation of foam reduces the effective volume of the fermenter and reduces the loading factor, which means that the amount of enzyme that can be produced in the same tank volume is reduced, thereby reducing the efficiency of the equipment. In the current industrial fermentation process, defoamers are usually used to remove bubbles.

[0004] However, defoamers use chemical properties to remove bubbles. On the one hand, during the fermentation process, the fermentation tank is closed, so the defoamer needs to be poured into the fermentation tank in advance. Although it can be added according to the preset ratio, once a problem occurs, it cannot be changed, and the raw materials in the entire fermentation tank will be wasted. On the other hand, most defoamers are silicone-based. Although food-grade defoamers can be considered non-toxic and harmless, long-term consumption will still be harmful to health. Utility Model Content

[0005] Technical problem to be solved: How to eliminate bubbles without using defoaming agents in food additives.

[0006] Technical solution: The utility model provides an industrial enzyme preparation device, including a tank body structure and an integrated structure: the tank body structure includes a fermentation tank, a tank cover is arranged at the top opening of the fermentation tank, a connecting hole is penetrated through the middle of the tank cover, a bearing is installed in the connecting hole, and a vertical rod is penetrated and connected in the bearing; the integrated structure includes a plurality of blades fixed on the vertical rod, which are evenly distributed from top to bottom and located inside the fermentation tank, and the two ends of the blades are bent upward; in addition, on the one hand, a driving mechanism for driving the vertical rod to rotate is also arranged on the tank cover; on the other hand, a ventilation mechanism for ventilation is arranged on the tank cover.

[0007] Furthermore, the driving mechanism includes a servo motor installed on the top of the tank cover, and a reducer is connected between the servo motor and the vertical rod.

[0008] Furthermore, the bearing is a bearing group consisting of two upper and lower bearings, the bearing group forms a bearing seat through the outer shell, the outer wall of the bearing seat is fixedly connected to the inner wall of the connecting hole, and the inner rings of the two bearings on the bearing seat are interference fit with the vertical rod and penetrate through it.

[0009] Furthermore, the ventilation mechanism includes an air pipe connected to the top of the tank cover and communicating with the fermentation tank, the bottom end of the air pipe is located above all the blades, and the top end of the air pipe is connected to an openable plug.

[0010] Furthermore, the plug is composed of a vertical column and a round head. The vertical column is an elastic column, and the diameter of the elastic column is slightly larger than the inner diameter of the trachea; the diameter of the round head is greater than or equal to the diameter of the trachea.

[0011] Furthermore, the bottom end of the vertical column can be constructed to form a hemispherical structure. When the bottom end of the vertical column contacts the bottom end of the trachea, the hemispherical structure can reduce the friction between the bottom end of the vertical column and the top end of the inner wall of the trachea.

[0012] Technical effect: In the utility model, the combination of the vertical rod and the blades forms a stirring frame structure that can maintain the stirring effect on the raw materials. At the same time, the blades that are tilted upward at both ends can form an upward airflow when rotating, so that the lighter bubbles can move upward faster. When the bubbles move to the inside of the fermentation tank, these bubbles can be discharged to the outside through the ventilation mechanism; not only that, because these blades are distributed from top to bottom, the blades can also cut the bubbles in most areas of the fermentation tank when rotating to break the bubbles. In summary, through the above effects, the bubbles in the fermentation tank can be effectively reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The industrial enzyme preparation device provided in this specific embodiment is as follows: Figure 1 and Figure 2 As shown, it includes a tank structure and an integrated structure, wherein:

[0020] The tank structure includes a fermentation tank 1, and a tank cover 2 is arranged at the top opening of the fermentation tank 1. A connecting hole is opened in the middle of the tank cover 2, and a bearing is installed in the connecting hole. A vertical rod 4 is connected through the bearing. Specifically, the bearing 3 is a bearing group composed of two upper and lower bearings. The bearing group forms a bearing seat through the outer shell. The outer wall of the bearing seat is fixedly connected to the inner wall of the connecting hole. The inner rings of the two bearings on the bearing seat are interference-fitted with the vertical rod 4 and penetrate. Such a structural design is more conducive to maintaining the stability of the vertical rod 4.

[0021] The integrated structure includes a plurality of blades 5 fixed on a vertical rod 4 and evenly distributed from top to bottom and located inside the fermentation tank 1, and both ends of the blades 5 are bent upwards; in addition, on the one hand, a driving mechanism 6 for driving the vertical rod 4 to rotate is also provided on the tank cover 2, such as Figure 2 As shown, the driving mechanism 6 includes a servo motor 601 installed on the top of the tank cover 2, and a reducer 602 is connected between the servo motor 601 and the vertical rod 4; on the other hand, a ventilation mechanism for ventilation is provided on the tank cover 2, such as Figure 3 As shown, the ventilation mechanism includes an air pipe 7 connected to the top of the tank cover 2 and communicating with the fermenter 1. The bottom end of the air pipe 7 is located above all the blades 5, and the top of the air pipe 7 is connected to an openable plug 8. In this way, the combination of the vertical rod 4 and the blades 5 forms a stirring frame structure that can maintain the stirring effect on the raw materials. At the same time, the blades 5 with both ends tilted upward can form an upward airflow when rotating, so that the lighter bubbles can move upward faster. When the bubbles move to the inside of the fermenter 1, these bubbles can be discharged to the outside through the air pipe 7 in the ventilation mechanism; not only that, because these blades 5 are distributed from top to bottom, the blades 5 can also cut the bubbles in most areas of the fermenter 1 when rotating to break the bubbles. In summary, through the above effects, the bubbles in the fermenter 1 can be effectively reduced.

[0022] The plug 8 described above is composed of a vertical column and a round head. The vertical column is an elastic column, and the diameter of the elastic column is slightly larger than the inner diameter of the trachea 7; the diameter of the round head is greater than or equal to the diameter of the trachea 7. In addition, the bottom end of the vertical column can be constructed to form a hemispherical structure. When the bottom end of the vertical column contacts the bottom end of the trachea 7, the hemispherical structure can reduce the friction between the top end of the inner wall of the trachea 7 and the vertical column.
