During the rotation of the centrifuge tank, the materials can be subjected to a more uniform centrifugal force, which promotes the uniform mixing of the materials and ensures the consistency of the distribution of kiwi enzyme in each centrifuge tank, thereby avoiding the problem of incomplete fermentation or local over-fermentation caused by uneven distribution of materials, thereby improving the overall fermentation efficiency and yield.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] As attached Figure 1 and attached Figure 2 The anaerobic fermentation equipment of kiwi enzyme shown in the figure includes a shell 1, which is divided into an internal cavity and a bottom cavity from top to bottom. The top and bottom cavities of the shell 1 are made of stainless steel, and the internal cavity is made of translucent plastic material, allowing light to penetrate, making it convenient to observe the internal fermentation process and protecting the internal environment from external pollution. A driving motor 2 is provided on the top of the shell 1. The driving motor 2 is a high-efficiency adjustable motor that can adjust the required speed and torque. The driving shaft at the bottom of the driving motor 2 is connected to the rotating bracket 4. The rotating bracket 4 is used to support the centrifugal tank 5 inside the fixed shell 1 and keep its structure stable. There are two groups of centrifugal tanks 5, and the two groups of centrifugal tanks 5 are evenly arranged along the horizontal direction of the rotating bracket 4. They rotate under the action of the driving motor 2, as shown in the attached figure. Figure 3As shown, a limit shaft 7 is provided at the bottom center of the centrifuge tank 5, and a circular track 8 is provided at the bottom of the internal cavity of the shell 1, which can accommodate the movement of the limit shaft 7 therein, thereby making the motion trajectory of the centrifuge tank 5 controllable during rotation. At the same time, a vacuum feeding mechanism 3 for conveying materials to the centrifuge tank 5 is connected to one side of the top of the shell 1, and an inflation pipe 17 connected to the internal cavity of the shell 1 is provided on the side of the shell 1 away from the vacuum feeding mechanism 3. Nitrogen is filled between the internal cavity of the shell 1 and the centrifuge tank 5 through the inflation pipe 17 to maintain strict anaerobic conditions. At the same time, the presence of nitrogen between the shell 1 and the centrifuge tank 5 can keep the temperature of the material in the centrifuge tank 5 stable and reduce the influence of the ambient temperature.

[0024] Illustratively, a feed port 6 is provided at the top of the centrifuge tank 5, and the feed port 6 is equipped with a sealing cover to maintain the sealing of the centrifuge tank 5 during the non-feeding period to prevent air from entering, and a discharge port 9 is provided at the bottom of the centrifuge tank 5 on one side of the limiting ball 7, and the discharge port 9 is equipped with a sealing cover to maintain the airtightness of the inside of the centrifuge tank 5 during the non-discharging period.

[0025] Exemplarily, the vacuum feeding mechanism 3 includes a storage tank 11, a No. 1 vacuum pump 12 and a telescopic tube 13. The storage tank 11 is placed on one side of the shell 1, and the No. 1 vacuum pump 12 is arranged on the top of the storage tank 11, and the pipeline of the No. 1 vacuum pump 12 is connected to the telescopic tube 13. The telescopic tube 13 passes through the top of the shell 1 and can be displaced up and down vertically along the top inner wall of the shell 1. When the equipment is in the feeding state, by starting the No. 1 vacuum pump 12, the air in the storage tank 11 and the telescopic tube 13 is extracted to form a negative pressure environment. At this time, since the interior of the centrifugal tank 5 is also in a negative pressure state, the telescopic tube 13 stretches under the action of the pressure difference and is automatically tightly connected with the feed port 6. The sealing cover of the feed port 6 automatically opens under the action of the pressure difference, allowing the material in the storage tank 11 to enter the centrifugal tank 5 through the feed port 6. After the material is transported, the No. 1 vacuum pump 12 is turned off, the telescopic tube 13 shrinks upward, disconnected from the feed port 6, and the sealing cover of the feed port 6 is automatically closed.

[0026] Exemplarily, the vacuum discharging mechanism 10 includes a connecting pipe 14, a No. 2 vacuum pump 15 and a discharge pipe 16. The connecting pipe 14 is fixed to the bottom of the internal cavity of the shell 1. The two groups of centrifuge tanks 5 are actively controlled to stay on the connecting pipe 14 in turn, so that the discharge port 9 is connected to the connecting pipe 14. The size and shape of the connecting pipe 14 should ensure that it matches the discharge port 9 of the centrifuge tank 5. One side of the connecting pipe 14 is connected to the No. 2 vacuum pump 15, and the other side of the No. 2 vacuum pump 15 is connected to the discharge pipe 16. The inner diameter of the discharge pipe 16 is large enough to facilitate the smooth passage of the fermented kiwi material.

[0027] Furthermore, the storage tank 11 and the discharge pipe 16 are usually made of food-grade stainless steel, with a smooth internal surface to reduce material residue, and have good sealing properties to maintain internal pressure conditions, while the telescopic tube 13 is usually made of food-grade silicone and can expand and contract under the action of vacuum attraction to adapt to the feed port 6 at different positions.

[0028] Illustratively, the centrifuge tank 5 is made of light-transmitting glass material, so that the operator can directly observe the fermentation process, including material mixing, foam generation, etc., which facilitates real-time monitoring and adjustment of fermentation parameters.

[0029] The working principle of the utility model is as follows: first, the processed kiwi fruit material is loaded into the storage tank 11, and the No. 1 vacuum pump 12 is started to extract the air in the storage tank 11 and the telescopic tube 13 to form a negative pressure environment. At this time, the telescopic tube 13 is automatically and tightly connected with the feed port 6 of the centrifuge tank 5 under the action of the pressure difference. Under the action of vacuum attraction, the kiwi fruit material in the storage tank 11 is sucked into the centrifuge tank 5 through the telescopic tube 13. After the material is added to the centrifuge tank 5, the drive motor 2 is started and the centrifuge tank 5 is driven to perform circular motion through the rotating bracket 4 and the circular rail 8 system. This process helps to mix the materials evenly and start fermentation. During the entire fermentation process, nitrogen is filled into the internal cavity of the shell 1 and the centrifuge tank 5 through the inflation pipe 17 to maintain strict anaerobic conditions, which helps to inhibit the growth of aerobic microorganisms, protect sensitive ingredients, and improve product purity and quality. After the fermentation is completed, the No. 2 vacuum pump 15 is started to form a negative pressure inside the centrifuge tank 5 through the connecting pipe 14, which promotes the fermented material to be discharged along the discharge pipe 16.

[0030] Obviously, the above-mentioned embodiments are only preferred embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
